The effects of replacement of maize grain with ancient wheat by-products on intestinal morphometry and enzymatic activity in laying hens was studied. Eighty hens were divided into two groups (40 each, 8 replicates, 5 hens/replicate) fed two isoproteic and isoenergetic diets. In the treated group, part of the maize was replaced by a mix of ancient grains (AGs) middling, in a 50:50 ratio of Triticum aestivum L. var. spelta (spelt) and Triticum durum dicoccum L. (emmer wheat). The AG diet affected the weight of all the large intestine tracts, decreasing the weight of caeca (p< 0.01) and increasing those of colon (p< 0.01), rectum and cloaca (p< 0.05). Villus height in the AG group was higher (p< 0.01) than the control for the duodenum and jejunum, while for the ileum, the control group showed the highest values (p< 0.01). The submucosa thickness was higher (p< 0.01) in the control group for the duodenum and ileum, while the jejunum for the AG group showed the highest (p< 0.05) submucosa thickness. The crypts depth was higher (p< 0.01) in the control group for the duodenum and ileum. Enzyme activity was enhanced by AGs (p< 0.01) in the duodenum. Regarding the jejunum, sucrase-isomaltase and alkaline phosphatase had higher activity (p< 0.05 and p< 0.01, respectively) in the AG group. In the ileum, sucrase-isomaltase showed higher activity (p< 0.01) in the control group, while alkaline phosphatase showed the highest values (p< 0.05) in the AG group. Overall, results suggested that the dietary inclusion of AGs exerted positive effects in hens, showing an improved intestinal function.

The aim of this work was to propose a model of free-range raising for rabbit able to maximize the animal welfare and at the same time the productive performances through the use of mirrors. A total of 81 rabbits were allocated into free-range areas and divided into three groups (nine replicates per group): in the first group (face to face, F2F), the rabbits of each replicate could see each other. In the second group (blind) each replicate was isolated from the others; in the third group (mirrors), the replicates were divided as for the Blind group but two mirrors were placed in a corner of the perimeter. The blind group rabbits showed the lowest final weight (p < 0.05), while rabbits from the mirrors groups showed the best FCR and net dressing out values. The blind group showed the highest production of total short chain fatty acids, acetate (p < 0.05) and propionate (p < 0.01). The F2F rabbits showed higher levels of creatine phosphokinase and lactate dehydrogenase and lower values of blood glucose than those of the other groups, due to the higher locomotion activity. The use of mirrors can improve rabbit’s growth performance and carcass traits by lowering the rabbit’s locomotion activity in comparison to the other tested systems.

Growth performances and meat quality of free-range or cage raised rabbits were compared in 36 male animals. Rabbits were raised in free-range areas (2000 cm2/head) or in open-air cages (800 cm2/head) from weaning to 99 days old. Daily weight gain and final live weight were higher (P < 0.05) for the rabbits raised in cages which presented a more favourable feed conversion ratio (P < 0.05) than in the free-range group. The average feed intake, liver and empty gastro-intestinal tract weights were higher (P < 0.05) in the free-range group, while the interscapular fat percentage was higher (P < 0.05) in the caged rabbits. Loins of free-range rabbits had higher amount of PUFA n-6 in neutral lipids (P < 0.05) whereas their polar lipids were richer in PUFA n-6 and n-3 than in those of the cage group. Muscular fat of free-raised rabbits was found to be less susceptible to be oxidized, having a higher antioxidant capacity than the caged group.

To investigate the effect of two insect meals (from Hermetia illucens, HI and Tenebrio molitor, TM larvae) on productive performance and blood profiles of Barbary partridge, ninety, seven days old partridges were divided into 5 groups (6 replicates, 3 partridges/replicate). Up to 64d, the groups fed 5 isoproteic and isoenergetic diets: the control fed a corn-soybean meal diet (SBM group); in TM25 and TM50 groups the 25 and 50% of SBM proteins were substituted by the protein from TM, respectively; in HI25 and HI50 groups the 25 and 50% of SBM were substituted by the protein from HI, respectively. The birds fed TM25 and both the HI levels reached a higher (P<0.01) live weight at 64d than the control. Considering the entire experimental period the TM groups had a more favorable FCR than SBM. The carcass weights of all the insect groups were higher (P<0.01) than the control. The weight of the full digestive tract in SBM group was the highest (P<0.01). The caecal weight, the intestinal and caecal length were the highest (P<0.01) in the SBM group. The SBM group the highest value of albumin/globulin (P<0.01) and creatinine (P<0.05). TM seems to be more effective than HI in improving FCR. The reduced albumin/globulin ratio in the insect meal fed groups could be ascribed to the chitin content and this result was not affected by the amount of chitin intake, suggesting that also the lowest values are able to express their potential effects in partridges.

The study investigated the effect of low-crude protein (CP), essential aminoacids (EAAs) and conjugated linoleic acid (CLA) on broiler growth performance. From 1 to 6 days of age, 196 male broiler chicks fed the same basal diet containing 22.5% of crude protein. From 7-28 days the chicks were assigned to 7 treatments (4 replicates, 7 birds/replicate). The control group fed a 21.5% CP diet, supplemented with dl-methionine (Met) and l-lysine (Lys). The low-CP diet (19% CP) was supplemented with Met + Lys (2EAAs group) or with Met, Lys, l-arginine, l-tryptophan and l-threonine (5EAAs group); 2EAAs and 5EAAs groups were also supplemented with 0, 2 or 4% CLA. The body weight gain (BWG) was the biggest (p < .01) in the control group; 2EAAs and 2EAAs 4% CLA groups had lower BWG than the three groups fed 5EAAs diets. Diet 5EAAs +2% CLA induced lower (p < .01) feed conversion ratio (FCR) than 5EAAs +4% CLA and also showed the lowest (p < .01) protein intake. Reducing CP in broiler diet increased (p < .01) the digestibility of CP. The total protein content of plasma was greater (p < .01) in 2EAAs +4%CLA and 5EAAs +4%CLA than in the control. Decreasing the protein content of the diet from 21.5 to 19.0% penalised the growth performance of broilers from 7 to 28 days of age and the administration of CLA at 2 or 4% was not able to support growth. However, addition of 5EAAs without or with 2 or 4% of CLA resulted in recovery of FCR and PCR.

The aims of this study were to evaluate the correlation between in vitro crude protein digestibility coefficients of insect meals from Tenebrio molitor (TI) and Hermetia illucens (HI) and their chemical composition traits as well as to develop regression equations able to estimate the in vitro crude protein digestibility (CPd) from proximate analysis of insect meals. Twelve samples of insect meals (6 from TM larvae, TM 1-6 and 6 from HI larvae, HI 1-6) were obtained from different producers and analysed for chemical composition and in vitro crude protein digestibility by a two-step enzymatic method (digestion with pepsin and trypsin-enriched pancreatin). For both insect meal samples, CPd was negatively correlated to ADF and chitin contents, while just for HI there was a positive correlation (P<0.01) between CP percentage of the samples and CPd. For both insect meals the former variable chosen in the stepwise analysis was the chitin, explaining the 79.45% of CPd variability for Tenebrio molitor samples and the 98.30% for Hermetia illucens. In the second step, the amount of protein linked to ADF was added in the model for T. molitor and CP for H. illucens samples. The coefficients chitin is the main constituent of insect body able to affect the crude protein digestibility of Tenebrio molitor and Hermetia illucens larvae meals estimated by an in vitro enzymatic method.

A total of 420 21-day-old broilers were wing banded and randomly distributed among 60 cages of 7 birds per cage during days 21-37 of age. A factorial design (4×3) was used in which there were four feed forms (mash vs. pellet diet with diameter 2-2 mm, 2-3 mm and 3-3.5 mm, respectively) and three enzyme treatments (unsupplemented, phytase, phytase plus multi-enzyme). Each treatment was replicated 5 times with 7 broilers per replicate. Body weight gain of broilers fed 2-3 mm-diet was significantly greater than that of those fed mash diet and 2-2 mm or 3-3.5 mm pellet-diet. Feed conversion ratio was the best in broilers fed 2-3 mm and 3-3.5 mm pellet-diets. However, feed intake was significantly lower in broilers fed pellet-diets than that of those fed the mash diet. The production index and economic efficiency were significantly higher in groups fed 2-3 mm pellet diameter compared to those fed 2-2 mm and 3-3.5 mm pellet diets. Digestibility of crude protein, ether extract, crude fibre and crude ash were significantly and similarly greater in groups fed pellet diets in comparison with those fed mash diet. Enzyme supplementations significantly and similarly increased growth and production index whereas improved feed conversion ratio and economic efficiency than the control group and this concurred with greater digestibility of crude protein, ether extract and crude ash. However, multi-enzymes plus phytase induced greater effect on the production and economic traits than phytase alone showing synergetic effects. Pellet diet at 2-3 mm supplemented with multi-enzyme plus phytase resulted in the highest performance and nutrient digestibility of broilers during day 20-37 d of age.

Four hundred-twenty broilers were used in a factorial design (4×3) in which four feed forms (mash vs. pellet diet with diameter of 2 mm, 3 mm and 3.5 mm, respectively) and three enzymes treatments (unsupplemented, phytase, phytase+multi-enzyme) were used. Each treatment was replicated five times (7 broiler/replicate). Feed form had no effects on most of carcass traits and physical characteristics of meat, but pellet diets decreased the relative weight of gizzard and caecum length. Feeding 3.5 mm pellet diets increased abdominal fat compared to that of broilers fed mash diets. Pellet with 3 mm diameter increased and decreased respectively meat fat and moisture. Pellets with 3.5 mm diameter increased meat ash compared to broilers fed mash diet. Levels of plasma glucose and alanine aminotransferase of broilers fed 2 mm pellet, cholesterol of broilers fed 3 mm pellet and albumin/globulin ratio, monocytes and red blood cells of broilers fed 3.5 mm pellet were significantly higher than those of broilers fed mash diet. Haemoglobin, phagocytic activity, heterophils and heterophils/lymphocyte ratio were higher in groups fed mash diets and 2 mm pellet. Packed cell volume and phagocytic index were the highest in group fed mash diets. Phytase or multi-enzyme+phytase increased carcass yield, total edible parts and decreased inedible parts compared to broilers fed diet without enzyme supplementation. Enzyme supplementations significantly and similarly increased plasma glucose, total protein, triglycerides, red blood cells and phagocytic activity and decreased phagocytic index in comparison to the control group. However, phytase alone decreased cholesterol and increased monocytes by contrast with the control group. Multi-enzymes+phytase induced greater effect on white blood cells than phytase alone.

The aim of this study was to improve knowledge on the effect of group size on productive performance and egg quality of hens raised in furnished cages equally designed. A total of 520, 15-week-old Lohmann Brown laying hens were divided into 2 groups to have a similar initial body weight (average 1392±16.3 g). The cages of S25 group (240 L x 78 W x 50 H cm, 749 cm2/hen) hosted a total of 200 hens, while those of S40 group (462 L x 65 W x 50 H, 751 cm2/hen) included 320 birds. Experimental data were recorded after an adaptation period of 5 weeks (20 to 36 weeks of age). Hens were submitted to 15 h of light/d. The average temperature inside the building was 24.6±2.5°C over the entire experimental period with higher values at 24, 26, 28 and 30 weeks of age. The relative humidity recorded inside the building was 55% at week 20 and 60% all through the experimental period. Hens raised from S40 group had lower percentage of egg production (84.91 vs 88.90%, P<0.01) and higher feed conversion ratio (2.70 vs 2.25, P<0.0001) than S25 group. The percentage of eggs laid out of the nest was higher in S25 than S40 group (0.26 vs 0.19%, P<0.01). As expected, the week of age affected almost all the parameters (feed intake, body weight, laying percentage, egg weight, yolk, shell and albumen indexes, shell thickness, Haugh unit). However, the effect of group size was particularly evident during the hot period.

One hundred forty-four sharpsnout seabream of about 100 g initial body weight were randomly stocked in 12 experiment tanks (180 L). Testing conditions included 12 fish per tank, with triplicate tanks for treatment. The experimental period lasted 150 days. Average water temperature was 21.9±1.6°C, salinity was 30.0‰ and pH ranged from 7 to 8, throughout the experiment. A control diet (FM) was made from fish meal. One similar diet (SBM) was made with approximately 40% of the protein supplied by soybean meal. The remaining two diets (SBM-MOS and SBM-INU) were formulated adding 8 g of mannanoligosaccharide (MOS) and inulin (INU) per kg of the SBM diet, respectively. The results showed that mean final weight (average values 234.4 g), specific growth rate (average values 0.585), feed conversion rate (average values 2.05) and protein efficiency ratio (average values 1.01) were unaffected by MOS or INU supplementation to SBM diet. Body proximate composition was affected by MOS and INU supplementation. Fish fed SBM-MOS and SBM-INU diets showed the highest moisture level and the lowest lipid content. Also the total polyunsaturated fatty of the lipids was reduced by MOS and INU in comparison to SBM diet alone.

A total of 210 unsexed 1-day old Arbor Acres broiler chicks were wing banded and randomly distributed among 30 cages of 7 birds per cage keeping equal initial BW during days 1–20 of age. A factorial design (2×3) was used in which there were two feed forms (mash vs crumble diet) and three enzyme treatments (unsupplemented, phytase, phytase plus multienzyme). Each treatment was replicated 5 times with 7 chicks per replicate. Body weight (BW), body weight gain (BWG) and feed conversion ratio (FCR) of fed chicks were significantly improved when the crumble diet was administered. However, feed intake of chicks fed on the crumble feeds was significantly lower than those fed the mash diet. Digestibility of ether extract and crude fiber was significantly greater in groups fed the crumble diet than those fed the mash diet. Enzyme supplementation significantly and similarly increased growth and production index, and improved FCR. Also greater digestibility of crude protein and crude ash was observed but growth during days 8–14 of age and crude fibre digestibility were significantly greater in chicks receiving the multienzyme plus phytase supplement than those receiving phytase alone. Crumble feed supplemented with multienzyme resulted in the highest performance and nutrient digestibility of broilers during days 1–20 of age.

One-hundred-forty-four sharpsnout seabream of about 100 g initial body weight were randomly divided in 12 experimental tanks (180 litre each). Testing conditions included 12 fish per tank, with triplicate tanks for treatment. The experimental period lasted 114 days. Average water temperature was 21.9±1.6°C, salinity was 30.0‰ and pH ranged from 7 to 8. Four isonitrogenous-isolipidic diets were tested: a control diet (FM) with fish meal as the sole protein source; a second diet (SBM) with approximately 40% of the protein supplied by soybean meal. The remaining two diets were formulated adding 8 g of MOS and FOS per kg of the SBM diet respectively. Average final weight, specific growth rate, feed conversion ratio and protein efficiency ratio remained unaffected by partial fish meal substitution and by MOS or FOS supplementation. Also apparent digestibility coefficients values for organic matter, protein, lipid and energy were not significantly affected by dietary treatment.

After a brief discussion on the chemical-nutritional characteristics of the diets currently used in aquaculture, the authors focus attention on the problems associated with the replacement of fish meals with vegetable protein sources. The chemical composition of vegetable sources has a high variability and it is necessary to know the exact energy content and digestibility of amino-acids for each source. Another question is the occurrence of anti-nutritional factors in vegetable protein sources and their effect on diet palatability. The authors also underline that the use of high levels of vegetable sources increases the risk of contamination by mycotoxins of which the effects on the health of fish are not yet completely clear.

SummaryThe in vitro gas production technique was used to observe the fermentation characteristics of three feedstuffs (barley, dried alfalfa meal, and dried beet pulp). Inocculum was provided from the caecal contents of suckling rabbits (23, 26, 31 and 35d old) which had access to their dams’ food. Mean OM degradation increased progressively with the age of the rabbits (Pin vitro gas production technique is a valid tool for the study the development of caecal microbial activity in rabbits.

The effects of collection regimen and time of year on rabbit semen production were determined in this study. A total of 14 crossbreed Hyla bucks were used in winter and summer. In each season, rabbits were assigned to two groups. In group 1, (n = 7) rabbits were subjected to an extensive collection regimen (two ejaculates per male, once daily/week) and in group 2, (n = 7) a semi-intensive semen collection regimen was performed (two ejaculates per male, twice weekly). The traits recorded for each sample were libido, volume, pH, motility, sperm concentration, percentage of alive spermatozoa and sperm abnormalities. The results obtained in this study indicate that when increasing collection frequency, the rate of useful collections decreased (from 0.81 +/- 0.017 to 0.69 +/- 0.016; p < 0.01). The rate of useful collection also decreased in the transition from winter to summer (from 0.79 +/- 0.018 to 0.70 +/- 0.017; p < 0.01). Among the ejaculate characteristics studied, only volume/ejaculate (from 0.64 +/- 0.015 to 0.53 +/- 0.017; p < 0.01) and spermatozoa/ml (from 406 +/- 15 to 359 +/- 13 million; p < 0.01) appeared negatively affected by collection. In winter fewer volume/ejaculates were produced (0.55 +/- 0.015 vs 0.60 +/- 0.016 ml; p < 0.01) and fewer spermatozoa/ml (360 +/- 14 vs 394 +/- 16 million; p < 0.01) than in summer. The doses produced per ejaculate decreased as collection frequency increased, but the number of doses produced per week was higher in the semi-intensive than the extensive rhythm (26.5 +/- 2.1 vs 20.9 +/- 1.5; p < 0.01). The results suggest that a semi-intensive rhythm may be viewed favourably.
