Free faecal liquid (FFL) in horses is characterised by the excretion of faeces in two phases (one solid and one liquid), which may cause dermatitis on the hindlegs. The causes of FFL are not known. Results from previous studies have indicated that feed ration composition and management factors may play important roles in the occurrence of FFL. A case–control study was therefore performed in which data on feed rations, feeding practices and management factors were compared between horses with (case) and without (control) FFL on 50 private farms in Sweden and Norway. The comparisons show that case and control horses were reported to be fed similar average amounts of wrapped forage (p = 0.97) and to be subject to similar management practices, but case horses were fed higher proportions of concentrates in their diet (p< 0.001) and lower average amounts of straw and lucerne (p< 0.05) compared to control horses. Case horses were reported to be fed twice as much concentrate per 100 kg BW and day as control horses and a higher daily intake of starch and water-soluble carbohydrates (p< 0.05). Case horses also had a lower daily intake of digestible crude protein and neutral detergent fibre compared to control horses (p< 0.05). These differences were small but are of interest for further studies of factors causing FFL.

Urban/peri-urban dairying in East Africa used to be typified by elephant grass (Pennisetum purpureum, Schumach) as the primary forage. However, the ever-declining space for farming has made forage cultivation increasingly difficult. As a coping strategy, farmers are harvesting vegetation biomass from natural environment, particularly common reed (Phragmites australis, Cav.) from wetlands. This study aimed to compare elephant grass and common reed in terms of chemical composition and in situ rumen degradation. Samples were collected (in dry and wet seasons) and analyzed for chemical composition, and in situ rumen degradation of dry matter (DM), crude protein (CP), and neutral detergent fiber (NDF) determined. Rumen degradation was determined by incubating triplicate nylon-bagged samples in rumens of three cannulated Ankole–Friesian crossbred steers. The CP content ranged from 10.8% to 16.2% DM (common reed), and 9.9–12.5% DM (elephant grass). Common reed showed lower DM, and ADF compositions, and higher effective rumen degradability of DM, CP, and NDF in both seasons. For both forages, CP content was higher during the dry season, while effective rumen degradability of DM, CP, and NDF were higher in the wet season. In summary, the chemical and rumen degradation results suggest that common reed may be nutritionally superior to elephant grass.

Eight locally available protein source ingredients in Tanzania were selected for assessment of apparent digestibility (AD) in tilapia Oreochromis niloticus, using faeces samples collected by siphoning or stripping. The selected protein source ingredients were Lake Victoria sardines (FM), brewers spent yeast (BSY), moringa leaves (ML), freshwater shrimp (FSH), marine shrimp (MSH), cattle blood (CB), duckweed (DW) and fish frames (FF). The AD (%) of dry matter (DM), organic matter (OM) and crude protein (CP) was unaffected (p > 0.782–0.901) by the faeces collection method (i.e., siphoning or stripping), with correlation coefficient (r) of 0.98, 0.99 and 0.93 between AD values for DM, OM and CP, respectively, following siphoning and stripping. The AD (%) of DM, OM, CP and gross energy (GE) in the test ingredients differed (p < 0.0001). The AD (%) of DM and OM was lowest in BSY and DW, followed in increasing order by ML, MSH, FF, FSH and CB. In general, the AD (%) of CP was high (>76%), but with a low value (46%) for DW. The AD (%) of GE was closely correlated (r = 0.96) with the AD of OM. In conclusion, FSH, MSH, CB, FF, BSY and ML have acceptable protein digestibility to be used in tilapia diet formulation.

An investigative field survey was performed to gather baseline data on locally available feed ingredients and fish farming practices in different regions of Tanzania. More than 80% of respondents relied on locally available feed ingredients as a major feed supplement for their cultured fish, with maize bran being the most commonly used feed ingredient in all regions. Crude protein content in most analyzed local feed ingredients was medium-high, while crude fat content was high in some animal and agricultural by-products, and medium-low in other ingredients. Most respondents were males and the majority of fish farms were owned by individuals. Earthen pond was the most common fish farming system in all regions except Dar es Salaam. Semi-intensively mixed-sex tilapia monoculture was the dominating fish farming practice. The results of the survey presented provide a good platform for future development of culture systems and feeding strategies for tilapia in Tanzania.

Free faecal liquid (FFL) is a condition in horses where faeces are voided in one solid and one liquid phase. The liquid phase contaminates the tail, hindlegs and area around the anus of the horse, resulting in management problems and potentially contributing to impaired equine welfare. The underlying causes are not known, but anecdotal suggestions include feeding wrapped forages or other feed- or management-related factors. Individual horse factors may also be associated with the presence of FFL. This study, therefore, aimed to characterize horses showing FFL particularly when fed wrapped forages, and to map the management and feeding strategies of these horses. Data were retrieved by a web-based survey, including 339 horses with FFL. A large variety of different breeds, ages, disciplines, coat colours, housing systems and feeding strategies were represented among the horses in the study, meaning that any type of horse could be affected. Respondents were asked to indicate if their horse had diminished signs of FFL with different changes in forage feeding. Fifty-eight percent (n = 197) of the horse owners reported diminished signs of FFL in their horses when changing from wrapped forages to hay; 46 (n = 156) of the horse owners reported diminished signs of FFL in their horses when changing from wrapped forages to pasture; 17% (n = 58) reported diminished signs of FFL when changing from any type of forage batch to any other forage. This indicated that feeding strategy may be of importance, but cannot solely explain the presence of FFL. The results also showed that the horses in this study had a comparably high incidence of previous colic (23%, n = 78) compared to published data from other horse populations. In conclusion, the results showed that FFL may affect a large variety of horse types and that further studies should include detailed data on individual horse factors including gastrointestinal diseases as well as feeding strategies, in order to increase the chance of finding causes of FFL.

This study investigated the effect of providing extra water and nesting material to Moo Lath sows on piglet survival and growth. Three treatments were evaluated in a randomized block design with six sows/treatment. In the Control treatment, sows were not provided with nesting material or extra water apart from that included in the feed (conventional smallholder practice). In treatment NM, nesting material was provided 1–2 days before expected farrowing. In treatment NMW, nesting material as in NM and extra water were provided ad libitum throughout the study. Data on sow feed and water intake, plasma protein concentration (TPP), body weight, and re-mating period, and on litter size, body weight, and survival of piglets, were collected for two reproduction cycles. NMW sows had higher water intake than Control and NM sows (14.7, 4.5, and 4.5 L/day, respectively, SE = 0.2). The weight loss from 2 weeks prior to farrowing until weaning was smaller in NMW than in NM and Control sows (16.0, 23.8, and 22.9 kg, respectively, SE = 0.9). TPP dropped from farrowing until 21 days of lactation in NMW sows, whereas it increased or was unchanged in NM and Control sows. The re-mating period was shorter and the number of litters/year was higher in NMW than in Control and NM sows (2.2, 2.0, and 2.0, respectively, SE = 0.01). Piglet mortality was lower in NMW than in Control and NM (9.5, 43.9, and 26.7%, respectively, SE = 4.9). Piglets in NMW were heavier at weaning and had higher daily weight gain than Control and NM piglets. It was concluded that providing water ad libitum and nesting material improved piglet survival and growth, and that providing water ad libitum improved sow physiological and reproductive fitness. However, provision of nesting material without access to ad libitum water might increase susceptibility to heat stress in sows.

This study evaluated diets including whole or peeled (legs removed) crickets (Teleogryllus testaceus) in terms of diet digestibility, growth and nitrogen retention, using pigs as an animal model. The experiment included three iso-nitrogenous diets (18.4% crude protein) including either whole cricket meal (WC), body cricket meal (legs removed, BC) or fish meal (control) as the main protein source. Castrated male piglets (n=21, 30-45 days) with initial body weight 13.0±0.3 kg were allocated to one of the dietary treatments (7 piglets/treatment) in a fixed block design. The piglets were kept in single bamboo/wooden stalls with slatted floors and were adapted to the feeds and the housing for 5 days before starting the 25-day experiment. The diets were offered ad libitum, but close to appetite (approximately 5% of body weight). Feed intake was recorded and piglets were weighed every 5 days. During days 20-25, total collection of faeces and urine was performed. Dry matter and nutrient intake were higher for piglets fed the WC and BC diets than for those fed the control diet. From day 10, piglets fed BC and WC were heavier than piglets fed the control diet, but there were no differences between WC and BC. Dry matter digestibility was highest for diet WC, and ash, crude fibre and crude fat digestibility was higher for BC and WC than for the control diet. Feed conversion ratio was lower for the WC and BC diets than for the control diet, and nitrogen retention (% of digested) was higher. We concluded that field cricket meal is a nutritious feedstuff for mono-gastric animals, and most likely also for humans. Removal of legs did not facilitate or improve the digestibility values and nitrogen retention. Thus, in order to minimise food waste, crickets should not be peeled in this way if they are going to be processed into meal.

This study evaluated survival and growth of Cambodian field crickets (Teleogryllus testaceus) during captivity when fed a set of local weed species, agricultural and food industry by-products. Wild individuals were caught at two locations in Cambodia, kept in pens and fed commercial chicken feed until the second generation off-spring hatched. First larval stage nymphs from this generation were collected and used in a 70-day feeding trial with one control treatment (chicken feed) and 12 experimental treatments (rice bran, cassava plant tops, water spinach, spent grain, residue from mungbean sprout production, and Alternanthera sessilis, Amaranthus spinosus, Commelina benghalensis, Cleome rutidosperma, Cleome viscosa, Boerhavia diffusa and Synedrela nodiflora). The crickets were kept in plastic cages and feed intake, weight and survival of crickets were recorded weekly. Overall survival did not differ between chicken feed and the experimental treatments with the exception of crickets fed B. diffusa, which had lower survival. From day 35 to day 49, survival on A. sessilis was also lower (P

The feeding experiment was conducted to evaluate the efficacy of locally available feed resources for Tra catfish (Pangasianodon hypophthalmus) cultured a series of 21 hapa net cages installed in the earthen pond during a 4-month period. The reference diet contained fish meal as the main crude protein (CP) source, whilst in the seven test diets 20–100 % of the fish meal CP was replaced with CP from local feed ingredients: groundnut cake (GNC), cassava leaf meal (CSLM), sweet potato leaf meal (SPLM), soybean meal (SBM), golden apple snail meal (GASM) and shrimp head meal. There were differences (p < 0.05) among diets in final body weight, total weight gain, daily weight gain, specific growth rate, viscera-somatic weight (VSI%), hepato-somatic index (HIS%) and intra-peritoneal fat (IPF%). The respective values for the shrimp head meal diet were numerically highest, followed in descending order by the reference, GASM, GNC, SPLM, CSLM and SBM diet. Food conversion ratio, fish survival rate, total feed intake, feed utilisation, fish fillet and kidney proportions did not differ among the reference and test diets (p > 0.05). However, the viscera-somatic, hepato-somatic, kidney and intra-peritoneal fat indices differed among treatments (p < 0.05). These data show that fish meal protein can be replaced with protein from locally available plant and animal feed ingredient resources in feed cultured in net cages in pond for Tra catfish fingerlings in effectively compromising growth performance, feed utilisation or carcass traits of fish.

The aim of this study was to compare the influence of whole-grain rye bread (WGRB), whole-grain wheat bread (WGWB), and refined wheat bread (WB) on the gut metabolic fingerprint to increase the understanding of the mechanism behind health aspects related to whole-grain products. Five pigs with an initial weight of 46 kg were used in a changeover design, with 3 diets and 3 periods. The experimental diets consisted of WGRB, WGWB, and WB and were balanced with similar content of dietary fiber (adjusted with cellulose), protein, and fat. Each diet period lasted for 7 d. Fecal samples were collected during Days 4 through 7 in each experimental period. Nuclear magnetic resonance (NMR) was used to analyze metabolic profiles from the fecal samples. Principal component analysis of metabolic fingerprints showed that the type of bread influenced the metabolic profile and that WGRB influenced metabolic profiles differently compared with WGWB (P = 0.03) and WB (P = 0.04). Quantification of the short-chain fatty acids in the NMR data revealed differences with higher concentrations of lactate (P = 0.04) and lower molar proportions of acetate (P = 0.03) in rye bread compared with wheat breads.

The purpose of this study was to investigate how inclusion of chicory forage or ribwort forage in a cereal-based diet influenced the fecal microbial community (microbiome) in newly weaned (35 days of age) piglets. The piglets were fed a cereal-based diet without (B) and with inclusion (80 and 160 g/kg air-dry forage) of vegetative shoots of chicory (C) and leaves of ribwort (R) forage in a 35-day growth trial. Fecal samples were collected at the start (D0), 17 (D17) and 35 (D35) days after weaning and profiles of the microbial consortia were generated using terminal restriction fragment length polymorphism (T-RFLP). 454-FLX pyrosequencing of 16S rRNA gene amplicons was used to analyze the microbial composition in a subset of the samples already analyzed with T-RFLP. The microbial clustering pattern was primarily dependent on age of the pigs, but diet effects could also be observed. Lactobacilli and enterobacteria were more abundant at D0, whereas the genera Streptococcus, Treponema, Clostridium, Clostridiaceae1 and Coprococcus were present in higher abundances at D35. Pigs fed ribwort had an increased abundance of sequences classified as Treponema and a reduction in lactobacilli. However, the abundance of Prevotellaceae increased with age in on both the chicory and the ribwort diet. Moreover, there were significant correlations between the abundance of Bacteroides and the digested amount of galactose, uronic acids and total non-starch polysaccharides, and between the abundance of Bacteroidales and the digested amount of xylose. This study demonstrated that both chicory and ribwort inclusion in the diet of newly weaned pigs influenced the composition of the fecal microbiota and that digestion of specific dietary components was correlated with species composition of the microbiota. Moreover, this study showed that the gut will be exposed to a dramatic shift in the microbial community structure several weeks after weaning.

Heat shock proteins (HSPs) are a set of highly conserved proteins that can serve as intestinal gate keepers in gut homeostasis. Here, effects of a probiotic, Lactobacillus rhamnosus GG (LGG), and two novel porcine isolates, Lactobacillus johnsonii strain P47‐HY and Lactobacillus reuteri strain P43‐HUV, on cytoprotective HSP expression and gut barrier function, were investigated in a porcine IPEC‐J2 intestinal epithelial cell line model. The IPEC‐J2 cells polarized on a permeable filter exhibited villus‐like cell phenotype with development of apical microvilli. Western blot analysis detected HSP expression in IPEC‐J2 and revealed that L. johnsonii and L. reuteri strains were able to significantly induce HSP27, despite high basal expression in IPEC‐J2, whereas LGG did not. For HSP72, only the supernatant of L. reuteri induced the expression, which was comparable to the heat shock treatment, which indicated that HSP72 expression was more stimulus specific. The protective effect of lactobacilli was further studied in IPEC‐J2 under an enterotoxigenic Escherichia coli (ETEC) challenge. ETEC caused intestinal barrier destruction, as reflected by loss of cell–cell contact, reduced IPEC‐J2 cell viability and transepithelial electrical resistance, and disruption of tight junction protein zonula occludens‐1. In contrast, the L. reuteri treatment substantially counteracted these detrimental effects and preserved the barrier function. L. johnsonii and LGG also achieved barrier protection, partly by directly inhibiting ETEC attachment. Together, the results indicate that specific strains of Lactobacillus can enhance gut barrier function through cytoprotective HSP induction and fortify the cell protection against ETEC challenge through tight junction protein modulation and direct interaction with pathogens.

Apparent digestibility coefficients (ADCs) for four protein‐rich alternative feed ingredients, intact baker's yeast (Saccharomyces cerevisiae), extracted baker's yeast (S. cerevisiae), zygomycetes (Rhizopus oryzae) and blue mussel (Mytilus edulis), were determined for Arctic charr (Salvelinus alpinus) and Eurasian perch (Perca fluviatilis). Diets contained 30% of test ingredients, and ADCs were compared to a reference diet containing fish meal. For Arctic charr, ADCs for dry matter (DM, 71–99%), sum of amino acids (SAA, 84–99%) and gross energy (70–99%) were significantly lower for intact S. cerevisiae than for extracted S. cerevisiae, R. oryzae and M. edulis. The ADCs for the indispensable amino acids (IAA) in Arctic charr varied between 84% and 99%. Significant differences were found in ADCs for IAA between the test ingredients for Arctic charr, with higher values for extracted S. cerevisiae and M. edulis. The ADCs in Eurasian perch varied between 83% and 95% for DM, 89% and 98% for CP, 92% and 100% for SAA, 81% and 96% for gross energy. No significant differences were found for ADCs between the test ingredients in Eurasian perch, indicating a species effect on digestibility. Furthermore, the absence of intact cell walls had a positive effect on digestibility of S. cerevisiae for Arctic charr.

Chitinolytic activity, nutrient uptake and intestinal barrier functions were investigated in gut tissues of Arctic charr (Salvelinus alpinus) fed iso-nitrogenous diets based on fish meal, with or without inclusion of zygomycetes (Rhizopus oryzae). We found that gut tissue of Arctic charr had significant chitinase activity, of both endo- and exo-chitinase iso-forms. Moreover, the distribution pattern along the GI tract of Arctic charr differed between endo-chitinase and exo-chitinase. The endo-chitinase activity in stomach tissue and in the distal intestine was several hundred-fold higher than the exo-chitinase activity in stomach tissue. The greatest exo-chitinase activity was found in the distal intestine. The zygomycete-based diet resulted in higher chitinolytic activity in gut tissue compared to the fish meal-based diet. Disturbed intestinal integrity and increased uptake rate of the amino acid lysine were observed in the distal, but not proximal, intestine of fish fed the zygomycete-based feed.

The gastrointestinal (GI) tract of mammals is inhabited by trillions of microorganisms, resulting in exceedingly complex networking. The interaction between distinct bacterial species and the host immune system is essential in maintaining homeostasis in the gut ecosystem. For instance, the gut commensal microbiota dictates intestinal mucosa maturation and its abundant immune components, such as cytoprotective heat shock proteins (HSP). Here we examined physiological expression of HSP in the normal porcine GI tract and found it to be gut region- and cell type-specific in response to dietary components, microbes, and microbial metabolites to which the mucosa surface is exposed. Correlations between HSP72 expression and ileal Lactobacillus spp. and colonic clostridia species, and between HSP27 expression and uronic acid ingestion, were important interplays identified here. Thus this study provides novel insights into host-microbe interactions shaping the immune system that are modifiable by dietary regime.

Fish meal is the major source of animal protein in feed for cultured salmonid fish, but its availability is limited and it must eventually be replaced by alternative protein-rich feed ingredients. Zygomycetes (Rhizopus oryzae) is a fungus with protein-rich biomass that could replace fish meal protein in fish feed. Using an 1H NMR spectroscopy approach, we studied the metabolic pattern in liver tissues of Arctic charr (Salvelinus alpinus) fed a commercial diet with unknown composition (ST), a diet with all protein from fish meal (FM) and a diet with most of the protein from zygomycetes biomass (FZ). No significant difference (p ≥ 0.05) was found in spectral data between FM and FZ using the OPLS-DA fitted model. However, other models showed that diet ST clearly differed (p

Dietary fiber is associated with impaired nutrient utilization and reduced net energy values. However, fiber has to be included in the diet to maintain normal physiological functions in the digestive tract. Moreover, the negative impact of dietary fiber will be determined by the fiber properties and may differ considerably between fiber sources. Various techniques can be applied to enhance nutritional value and utilization of available feed resources. In addition, the extent of fiber utilization is affected by the age of the pig and the pig breed. The use of potential prebiotic effects of dietary fiber is an attractive way to stimulate gut health and thereby minimize the use of anti-microbial growth promoters. Inclusion of soluble non-starch polysaccharides (NSP) in the diet can stimulate the growth of commensal gut microbes. Inclusion of NSP from chicory results in changes in gut micro-environment and gut morphology of pigs, while growth performance remains unaffected and digestibility was only marginally reduced. The fermentation products and pH in digesta responded to diet type and were correlated with shifts in the microbiota. Interestingly, fiber intake will have an impact on the expression of intestinal epithelial heat-shock proteins in the pig. Heat-shock proteins have an important physiological role in the gut and carry out crucial housekeeping functions in order to maintain the mucosal barrier integrity. Thus, there are increasing evidence showing that fiber can have prebiotic effects in pigs due to interactions with the gut micro-environment and the gut associated immune system.

Trillions of microorganisms that inhabit the intestinal tract form a diverse and intricate ecosystem with a deeply embedded symbiotic relationship with their hosts. As more detailed information on gut microbiota complexity and functional diversity accumulates, we are learning more about how diet-microbiota interactions can influence the immune system within and outside the gut and host health in general. Heat shock proteins are a set of highly conserved proteins that are present in all types of cells, from microbes to mammals. These proteins carry out crucial intracellular housekeeping functions and unexpected extracellular immuno-regulatory features in order to maintain the mucosal barrier integrity and gut homeostasis. It is becoming evident that the enteric microbiota is one of the major determinants of heat shock protein production in intestinal epithelial cells. This review will focus on the interactions between diet, gut microbiota and their role for regulating heat shock protein production and, furthermore, how these interactions influence the immune system and the integrity of the mucosal barrier.

Chicken production is popular in Kampala City, Uganda. Indeed about 70 % of all poultry products consumed in Kampala are produced locally. However, the high cost of feed is a major limiting factor. As a consequence, chicken farmers are formulating and mixing their own feeds. However, these own-mixed feeds may not meet recommended nutrient levels. We therefore studied five classes of own-mixed chicken feeds: broiler starter, broiler finisher, chick mash, grower mash, and layer mash. Samples of the chicken feeds were collected from farmers in and around Kampala City. We analyzed crude protein, ether extract, crude fiber, total starch, ash, calcium, phosphorus, and gross energy contents of the feeds. The apparent metabolizable energy content was calculated. We compared data with dietary requirements recommended for chickens in the tropics. Results show that own-mixed rations contained 21.9–36.3 % less protein than minimum recommendations. Broiler rations contained 16.2–20 % less metabolizable energy than minimum recommendations, and their crude fiber content was 37.5–50 % higher than the maximum recommendation. Layer mash contained 66.7 % less calcium and 17.5 % less metabolizable energy than minimum recommendations. All the five classes of own-mixed chicken rations were very high in ash content, ranging from 17.0 to 21.2 %. We conclude that own-mixed chicken rations do not conform to the dietary recommendations. There is therefore a need to give chicken farmers training on feed formulation and mixing.
