Forty late-lactation Girgentana goats were used to study the effect of diets fed ad libitum and αS1-casein (CSN1S1) genotype on redox balance. The goats genotyped at CSN1S1 locus (A/A, A/F) were subjected to four feeding treatments different for percentage inclusion of dry and fresh forage: DAF100 (98% of Dry Alfalfa Forage), DAF65 (65% of Dry Alfalfa Forage), FSF100 (100% of Fresh Sulla Forage) and FSF65 (65% of Fresh Sulla Forage). Blood samples were analyzed for superoxide dismutase (SOD) and glutathione peroxidase (GPX) activity, reactive oxygen metabolites (ROMs), biological antioxidant potential (BAP) and non-esterified fatty acids (NEFA), beta-hydroxybutyrate (BHBA), albumin, glucose and cholesterol contents. The oxidative stress index (OSI) was calculated as percentage ratio of ROMs to BAP. Redox balance was improved by Sulla inclusion, as reflected in the lower OSI values found in FSF100 and FSF65 groups. DAF100 group displayed the highest GPX activity, while other groups exhibited the highest SOD activity. Fresh forage diets increased albumin concentration while no effect of tested factors was noted on glucose, NEFA, BHBA and cholesterol contents. The interaction diet × genotype was significant only for GPX activity. GPX and albumin were negatively correlated and were correlated positively and negatively with ROMs, respectively. Diet rather than genotype affects redox balance in dairy goats and a possible role of forage polyphenol compounds on oxidative status needs to be tested in future studies.

Durum wheat bran (DWB) is a by-product mostly used in feeding ruminants, contributing to decrease in the utilization of feeds suitable as foods for human consumption, thus improving the sustainability of livestock production. However, the potential benefits of DWB, due to its content in phenolic acids, mainly consisting of ferulic acid with antioxidant properties, have not been well clarified yet. Accordingly, in this experiment, 36 lactating cows divided into three groups received, over a period of 100 days, one of three concentrates including DWB at 0% (DWB0), 10% (DWB10), or 20% (DWB20). The concentrates were formulated to be isoproteic and isoenergetic and, to balance the higher fiber content of the concentrates with DWB, the hay in the diets was slightly reduced. During the trial, the group feed intake and the individual milk production were monitored, and cheese was made with bulk milk from each group. Milk yield and microbiological characteristics of milk and cheese were similar among groups, indicating no DWB effect on cows performance and fermentation process. Milk from DWB20 group resulted slightly higher in casein and curd firmness (a2r). In cows fed DWB, the higher polyphenol intake was responsible for higher blood contents of these bioactive compounds, that seemed to have contributed in reducing the level of reactive oxygen metabolites (ROMs), which were higher in DWB0 cows. DWB20 cheeses showed a higher polyphenol content, lower number of peroxides, and higher antioxidant capacity than DWB0 cheeses. DWB20 and DWB10 diets resulted less expensive. In addition, the DWB20 group showed the best indexes heFCE (human edible feed conversion efficiency = milk/human edible feed) and NFP (net food production = milk − human edible food), expressed as crude protein or gross energy. In conclusion, the DWB fed to dairy cows at 12% of diet dry matter (DM) can lead to benefits, such as the improvement of oxidative status of cows, milk quality, shelf-life, and functional properties of cheese, and might contribute to reduce the feeding cost and limit the human-animal competition for feeding sources.

The study investigated the effects of a polymorphism at the LEP gene intron 1 microsatellite region and its interaction with diet energy level on feed intake, milk traits, milk fatty acid composition, and metabolic state in goats. Sixteen Girgentana lactating goats at mid-lactation, selected on the basis of their genotype (8 goats homozygous 266 bp/266 bp, L genotype; 8 goats heterozygous 266 bp/264 bp, H genotype), were fed ad libitum according to a change-over design, with two diets at different energy levels reached with different hay inclusion: low energy diet (LE)-100% of hay; and high energy diet (HE)-65% of hay. No differences in milk yield and composition or in dry matter intake were found between leptin genotypes or between diets. Leptin genotype had no effect on plasma metabolite concentrations. The differences between diets were recorded for plasma β-hydroxybutyric acid (BHBA) concentrations with higher (p = 0.01) values for the HE compared to the LE diet (0.44 vs. 0.24 mmol/L, respectively). Nonesterified fatty acid (NEFA) values seem to indicate a positive energy balance in goats. No interaction genotype per diet was evident for most of the studied parameters. Fatty acid composition was strongly influenced by LEP genotype: L goats, compared to H goats, showed higher levels of monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), and 14:1/14:0 desaturation index; lower levels of saturated fatty acids (SFA); and a more favorable atherogenic index. These results seem to suggest an improvement of health characteristics of milk with the L genotype.

This study compared the effects of a short daily grazing time with those of permanent free-stall housing on the behaviour, oxidative status, immune response, and milk production of organically reared cows. During a 63-day period, two homogeneous groups of eight lactating Brown cows were allocated to either housing (H) in a free-stall building for 24 h/day. Feeding was based on a total mixed ration or grazing (G) on barley grass for 5 h/day, and housing in a free-stall structure with feeding was based on the same total mixed ration offered to the H group. With regard to behaviour, H cows spent more time idling, walking, drinking, and self-grooming, whereas G cows showed a greater intent to eat and interact socially. Moreover, G cows exhibited slightly higher reactive oxygen metabolites and similar biological antioxidant potential concentrations than the H group, which indicates that short grazing resulted in an almost negligible increase in oxidative stress and an unchanged antioxidant capacity. Skin tests, performed by injecting phytohemoagglutinin intradermally, indicated that G cows had thicker skin than H cows at the end of the trial, an index of a better cell-mediated immune response. Grazing did not affect milk yield but improved milk quality in terms of an increase in fat and a reduction in urea content, somatic cell count, and total microbial count. Milk from G cows was richer in saturated fatty acids, likely because of the contribution of palmitic acid present in the grazed barley grass, and also showed higher contents of some healthy fatty acids, such as rumenic acid and α-linolenic acid, and a lower omega-6/omega-3 ratio. These results show that including a short grazing time in the diets of organic dairy cows does not have negative consequences for milk production and contributes to improved milk quality as well as to a more efficient immune response in the cows.

As a result of the widespread applications and the use of milk and milk products in human nutrition, intense scientific interest has focused on identifying the components in milk that may be relevant to improving human health. Milk contains a heterogeneous mixture of secretory compounds with a wide variety of chemical and functional activities. Among these compounds, many indigenous minor bioactive compounds are present. This review provides an overview of the available knowledge on the polyamines, oligosaccharides and sphingolipids occurring in goat and sheep milk compared to cow milk. It has been highlighted that goat milk is richer in polyamines than is milk from other mammals and that the former represents a very appealing source of human-like oligosaccharides. Furthermore, it is interesting to note the effect that breed and polymorphism at the CSN1S1 locus exerts on the polar lipid content and oligosaccharides profile. Goat and sheep milk production plays an important role in the nutrition and economy of many countries around the world, especially in the Mediterranean area. Information on the bioactive properties of goat and sheep milk is an important tool for their use as a nutritional source for infants, in medicinal foods and for developing new markets.

The Cinisara is an autochthonous Sicilian bovine breed reared mainly for production of Caciocavallo Palermitano, a typical stretched-curd cheese. The distribution of A and B alleles at both the β-lactoglobulin (LGB) and κ-casein (CSN3) loci in Cinisara cows and their influence on milk traits and cheese yield and composition were analysed. The LGB alleles are associated with significantly different effects on whey protein level (lower for BB genotype, P<0.01), and casein index (higher value for BB genotype, P<0.001), while CSN3 alleles were associated with significantly different effects on milk yield and coagulation properties; the BB genotype showed higher values for milk yield (P<0.01) and curd firmness (a30P<0.01 and a2r P<0.01) and lower values for coagulation and curd firming time (P<0.01) than the AA genotype. Cheese made with LGB BB milk showed higher percentage protein recovery (P<0.01); cheese made with CSN3 BB milk showed higher percentage fat recovery (P<0.05).

This study was carried out to investigate the effects of Yerba Mate (YM) supplementation on nutrients’ degradation, in vitro dry matter disappearance, gas production and rumen ammonia concentration. Three rumen-fistulated Holstein Friesian cows were used for the in situ incubations and provided rumen liquor for in vitro incubations. The inclusion of YM in a control diet (pasture+pellets) affected some in sacco degradation parameters. YM supplementation decreased the effective degradability and degradation rate of pasture crude protein (CP), and it seems to slow down the degradation of pasture neutral detergent fiber. A significant increase of degradation of pasture acid detergent fiber (ADF) was detected after YM inclusion in the control diet. YM supplementation reduced in vitro gas production of pasture and ammonia concentration of pellets. The addition of YM in ruminant diet could decrease ammonia production and increase protein availability for productive purposes. The moderate presence of tannins in YM could have affected the degradation kinetics of pasture CP and ADF and the ammonia production of pellets.

Twelve milking Girgentana goats were allocated into 3 groups and fed 3 diets ad libitum in a 3×3 Latin square design with 3 periods. The diets were Sulla fresh forage ad libitum (SUL), Sulla fresh forage ad libitum and 800g/d of barley meal (SULB), and mixed hay ad libitum and 800g/d of barley meal (HB). Changes were observed in total polyphenol intake, plasma oxidative status, plasma polyphenol content, metabolic status, milk polyphenol content, and total antioxidant capacity. The fresh forage diets (SUL and SULB) increased dry matter, total polyphenol, nontannic polyphenol and tannin intakes, and the milk total protein, casein, milk total polyphenols, and milk free polyphenols compared with the HB diet. The intake of condensed tannins was higher in the SUL than in the HB group, and an intermediate value was recorded for the SULB group. Plasma from the SUL- and SULB-fed goats exhibited greater total antioxidant capacity and greater total polyphenol and free polyphenol levels compared with the plasma from the HB group. Positive correlations between plasma total antioxidant capacity and condensed tannins intake (r=0.43), plasma total polyphenol and total polyphenol intake (r=0.61), and plasma free polyphenol and milk total polyphenols (r=0.38) were observed. The correlation between milk free polyphenols and whey total antioxidant capacity (r=0.42) highlights the role of free polyphenols in the determination of the antioxidant activity of milk. These results indicate that Sulla fresh forage exerts an antioxidant activity due to its secondary compounds that provide additional antioxidant value and that Sulla forage appears to be a promising strategy for improving product quality.

This chapter is a survey of recent studies on native sheep and goat breeds with special emphasis on their role as a tool of sustainability. After a short overview, strategies for adding value to the local breeds are described together with a synthesis of measures in support of animal biodiversity in marginal areas of Mediterranean environment. In this direction, three case studies are reported in which the added value of local breeds arising from a typical and/or traditional product is investigated. The first one is on native sheep breeds from Apulian region and the PDO Canestrato Pugliese cheese, and it indicates that Altamurana and Apulian Merino breeds produce milk and cheese having nutritional characteristics and sensory properties distinguishable from non-native breeds. The second and third studies regard local goat breeds and local cheeses, Caciotta and Ricotta cheeses. As it appears from our discussion, Girgentana breed produces milk and Caciotta and Ricotta cheeses with distinguishable fatty acid profile, nutritional index and sensory properties compared to other breeds. These peculiarities add value to the Girgentana breed and therefore give a support in favour of this breed, amplifying its sustainable use. Finally, we point out that the high quantity of sialyloligosaccharides found in local Garganica breed compared to foreign breed appears as an interesting promising feature in the study of adding value to local breeds.

Milk Sialyloligosaccharides (SOS) play an important role in brain development and\ud increasing immunity in infants. The few studies on goat colostrum and milk OS have shown similar profile to human milk and the highest content of SOS in comparison to other\ud ruminants. Considering the large importance given to OS to enrich infant formulas, this work\ud aimed investigating the content of three SOS, 3’-sialyllactose, 6’-sialyllactose and\ud Disialyllactose in colostrum and milk in two Italian goat breeds during lactation. The results\ud obtained showed significant effect of breed and sampling time on SOS content. The results\ud revealed that the Garganica colostrum and milk contained levels of 3’-SL and 6’-SL higher\ud than Maltese breed. The Maltese breed was characterized by interesting content of DSL.\ud Concerning stage of lactation, from Colostrum 0h to 24h the 3’-SL and DSL content\ud increased, while no significant increase of 6’-SL was detected. In milk sampled at 7, 30 and\ud 90 days after kidding, 6’-SL decreased significantly. A significant interaction Breed x\ud Sampling Time occurred for 3’-SL and DSL (P<0.001). Garganica breed showed the highest\ud content of 3’-SL (328.54 mg/L) in Colostrum 24h

We report and compare the partial genomic sequence (from part of Intron 1 to part of Exon 3) of goat, sheep, cattle and water buffalo leptin (LEP) genes. Genomic DNA was obtained from leukocytes of 117 goats belonging to six breeds (Angora, Alpine, Garganica, Girgentana, Maltese and Red Syrian); 30 sheep belonging to five breeds (Altamura, Sarda, Apulian Merino, Leccese, Apennine) 50 water buffaloes and 43 Italian Friesian cattle. All the four species had a microsatellite region in Intron 1. According to the results of a population analysis, we observed 10, 5, and 2 alleles, in cattle, water buffalo and goats, respectively, in this region. No nucleotide variation was observed in sheep. The results of this study show that in Red Syrian goats the two alleles are associated with significantly different effects on β-hydroxybutyric acid (P = 0.04) and free thyroxine (P = 0.018) levels, and milk somatic cell counts (P = 0.034). The same microsatellite region was tendentially associated with variation in insulin-like growth factor-1 (P = 0.082) and triglycerides (P = 0.072) levels. The results of this study are further evidence for the role of leptin as an indicator of metabolism and mammary gland health in dairy ruminants.

Polymorphism at the αS1-casein locus (CSN1S1) in goats influences several milk production traits. Milk from goats carrying strong alleles, which are associated with high αS1-casein (αS1-CN) synthesis, has higher fat and casein contents, longer coagulation time and higher curd firmness than milk from goats with weak alleles linked to low αS1-CN content. Nutrition also affects these milk properties; therefore, it is important to better understand the interaction between dietary characteristics and the CSN1S1 genotype in goats. This study aimed to investigate the effect of fresh forage based diet or energy supplement on feeding behavior, milk production, and metabolic and hormonal parameters of Girgentana goats with different genotypes at CSN1S1 loci. From a group of goats genotyped by PCR at the DNA level, 12 were selected because they had the same genotype for αS2-CN, β-CN, and κ-CN but a different genotype for αS1-CN: 6 were homozygous for strong alleles at the CSN1S1 loci (AA) and 6 were heterozygous for a weak allele (AF). Goats of each genotype were allocated to 3 subgroups and fed 3 diets ad libitum in a 3×3 Latin square design. The diets were sulla (Hedysarum coronarium L.) fresh forage, sulla fresh forage plus 800 g/d of barley meal (SFB), and mixed hay plus 800 g/d of barley meal (MHB). Diet had a stronger effect than CSN1S1 genotype. The SFB diet led to the highest energy intake, dry matter (DM) digestibility, and milk yield. The fresh forage diets (SFF and SFB) increased DM and crude protein (CP) intake, CP digestibility, and milk CN compared with the MHB diet. The diets supplemented with energy (SFB, MHB) reduced milk fat and urea, improved CP utilization for casein synthesis, and limited body fat mobilization, in accordance with a lower level of nonesterified fatty acids and higher levels of glucose and IGF-1. With regard to CSN1S1 genotype, AA goats showed higher CP digestibility and lower free thyroxine hormone and cholesterol levels than AF goats. Significant diet × genotype interactions indicated how AA goats, compared with AF goats, showed higher DM digestibility and milk yield when fed the SFB diet, which had more energy. A reduction in free triiodothyronine hormone occurred in AF goats fed the MHB diet, whereas no differences were observed in AA goats. These results demonstrate how goats with a higher capacity for αS1-CN synthesis exhibit more efficient energy and protein utilization, evident at the digestive level, and better productive responses to high-nutrition diets.

This study aimed to monitor the effect of a high (HD; 140% of energy requirements) versus a low diet (LD; 80% energy requirements) on oxidative status in goats during the peripartum period. Blood samples were taken from all goats at 2, 1, 0 (partum), +2 and +4 weeks from delivery. Blood samples were assayed for their content of reactive oxygen metabolites (ROMs), thiol (SH) groups, total antioxidant capacity (OXY) and for glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities. The observation that ROMs levels significantly increased during the peripartum period was accompanied by a decrease of GSH-Px activity at weeks 2 and 4 postpartum, which suggested that the goats might have experienced some degree of oxidative stress and lipid peroxidation. Overall, changes to the nutritional level of the diet had very little or no effect on redox homeostasis. The lack of any correlation between the biomarkers measured indicated that each oxidative stress marker responded differently, indicating that redox homeostasis was impaired in these dairy goats during the peripartum period

A study was carried out to evaluate how the energy level of the diet can affect milk production and quality in Girgentana lactating goats in relation to polymorphism at the αs1-casein (CSN1S1) genotype locus. Twenty-seven goats, homogeneous for milk production (1·5±0·3 kg/d), days of lactation (90±10 d) and body weight (35·8±5·5 kg) were selected on the basis of their CSN1S1 genotype, as follows: nine goats homozygous for strong (AA) alleles, nine goats homozygous for weak alleles (FF) and nine goats heterozygous (AF). The goats were used in a 3×3 factorial arrangement of treatments, with three genotypes (AA, FF, AF) and three diets at different energy levels (100%, 65% and 30% of hay inclusion). The experiment consisted of three simultaneous 3×3 Latin squares for the three genotypes, with one square for each level of hay inclusion in the diet. All the animals were housed in individual pens. Each experimental period lasted 23 d and consisted of 15 d for adaptation and 8 d for data and sample collection, during which the goats received the scheduled diet ad libitum. The animals were fed three different diets designed to have the same crude protein content (about 15%) but different energy levels: a pelleted alfalfa hay (H100) and two feeds including 65% (H65) and 30% (H30) of alfalfa hay (respectively 1099, 1386 and 1590 kcal NE for lactation/kg DM). All the diets were ground and pelleted (6 mm diameter). AA goats were more productive than AF and FF goats (respectively: 1419 v. 1145 and 1014 g/d; P=0·002). Indeed the interaction energy level×genotype was significant (P=0·018): in fact AA goats showed their milk increase only when fed with concentrates. Differences in protein and in casein levels between the three genotypes were in line with results expected from the different allele contribution to αs1-casein synthesis. Milk urea levels were significantly lower in AA goats compared with AF and FF genotypes (respectively 32·7 v. 40·4 and 40·4 mg/dl; P=0·049) and significantly lower when goats were fed with 65H and 30H diets than with 100H diet (respectively 37·4 and 34·3 v. 41·7 mg/dl; PP=0·043) occurred for milk urea, which was significantly lower in AA goats but only when fed with concentrates (65H and 30H). Blood concentrations of energy indicators (glucose, non-esterified fatty acids and beta-hydroxybutyric acid) were not influenced by genotype. The results confirm that strong alleles are associated with a greater efficiency of feed utilization and seem to show that a high energy level of the diet can further improve this efficiency.

The aim of the present work was to monitor the effect of a high versus a low diet on the metabolic and hormonal profiles of dairy goats and the progeny. Starting from the last month of pregnancy, 14 goats were randomly allocated to two groups: Low Diet (LD) and High Diet (HD) that received a diet that covered 80% and 140% of their energy requirements, respectively. Blood samples were taken from all goats, at −4, −3, −2, −1, 0 (partum), +1, +2, +3, +4, and +5 weeks from delivery. Blood samples were collected from goat kids on the day of birth prior to colostrum feeding (week 0) and then at 1, 2, 3, 4 and 5 weeks of age. Blood samples were assayed for their content of: urea, triglycerides, cholesterol, total protein, albumin, calcium and inorganic phosphorus, globulin, non-esterified fatty acids (NEFA), beta-hydroxy butyric acid (BHBA), insulin, free triiodothyronine (fT3), free thyroxine (fT4), leptin and prolactin (PRL). Kids’ live weights (LW) and growth rate were not affected by maternal nutrition. Milk yield was significantly (P < 0.05) higher in the HD goats. A significant (P < 0.001) effect of time was noted on plasma glucose, total protein, albumin, globulin and phosphorus concentrations. Concentration of plasma NEFA, BHBA, triglycerides and calcium were significantly (P < 0.01, P < 0.05, P < 0.001 and P < 0.05, respectively) higher in the LD goats than those in HD goats. Plasma insulin and PRL levels were higher in the HD goats than those in LD goats (P < 0.05 and P < 0.01, respectively). Plasma leptin level were lower on the day of partum (P < 0.05). Plasma glucose and insulin concentrations were higher in the HD kids than those in LD kids (P < 0.01) while plasma NEFA and triglycerides concentrations were higher (P < 0.05) in the LD kids than in the HD kids. Plasma leptin concentrations increased (P < 0.001) soon after kids began suckling but its values were not influenced by the dietary treatments. The thyroid hormones increased over time and their values were significantly higher in HD kids than those in LD kids at week 5. Our results showed that perinatal nutrition affects goats’ and kids’ metabolic and hormonal profiles; however this did not have an effect on foetal and kids’ growth. Nutrient restriction during pregnancy shifted nutrient partitioning towards the uterus to sustain foetal growth. This homeorhetic adaptation was continued during early lactation; however, it was not sufficient to sustain milk production.
