Although dried orange pulp (DOP) as a short-term dietary supplementation has been proven an effective substitute for cereals in goat diets–without impairing milk quality–there have been no studies considering its use over the full lactation period. This study evaluated replacing cereal with DOP in goat diets for the full 180-day lactation period on milk’s fatty acid (FA) and antioxidant composition. Payoya goats were assigned to three diet groups: a control group consuming a commercial concentrate with alfalfa hay as forage; a DOP40 or DOP80 group, wherein 40% or 80% of the cereal in the concentrate was replaced by DOP. The α-tocopherol and phenolic compounds levels and the antioxidant capacity in the milk increased as the DOP percentage increased. Including DOP might improve the FA indices of milk in the context of human health, especially when included at the end of lactation because it contributes to reducing the thrombogenicity index and increasing both the monounsaturated/saturated FA and polyunsaturated/saturated FA indices and the amounts of indispensables α-C18:3 n-3 and C18:2 n-6 cis. Ultimately, DOP presents a plausible alternative to cereals in the diet of goats throughout lactation to improve the nutritional milk quality, especially the healthy antioxidant capacity.

Often the only way to ensure profitability of Lacaune dairy sheep is intensive management, which requires appropriate dry-period treatment to ensure animal productivity and health. The present study aimed to investigate the effects of intramammary antibiotic dry therapy on the performance and health of Lacaune sheep under intensive management. We recorded data for 5981 complete lactation periods that followed a dry period. A total of 2402 lactation periods were preceded by a dry period involving intramammary administration of 300 mg of cephapirin benzathine (antibiotic group) and 3579 lactation periods were preceded by dry periods with no treatment (control group). The following on-farm yield data were collected for individual lactation periods: length of the subsequent lactation period; total milk yield per lactation period; daily milk yield and length of the subsequent dry period. Data on confounding factors that might affect productivity were also recorded, including the individual ewe, number of lactation periods and length of the previous dry period. Milk quality was assessed using data on somatic cell count (SCC) and content of protein and fat taken from the Spanish National Official Milk Yield Recording System. Antibiotic dry therapy significantly improved total yield per lactation period, which was 429±151·1 l in the antibiotic group and 412±165·5 l in the control group, as well as the daily milk yield, which was 1986±497·0 and 1851±543·2 ml/d, respectively (both P<0·0001). The initial dry period was significantly longer in the antibiotic group than in the control group, and dry period length correlated inversely with yield variables such us total yield per lactation period (r=−0·055; P<0·0001) and yield per day in milk (r=−0·039; P<0·0001). As a result, milk yield records systematically underestimated the positive effects of antibiotic dry therapy. Antibiotic dry therapy also significantly improved milk quality. Milk from the antibiotic group showed 50% lower SCC (573±1326 vs. 1022±2126 cells/ml; P<0·0001) and slightly higher content in fat (7·33±0·91 vs. 7·15±0·87%) and protein (5·63±0·44 vs. 5·44±0·4%). The results of this study suggest that cephalosporin dry therapy of Lacaune dairy sheep increases milk production and improves milk quality during subsequent lactation periods.

Abstract Background Foeniculum vulgare (fennel) is traditionally suggested for the fertility improvement in Iranian lore due to its antioxidant and phytoestrogen compounds. The present study aimed to investigate the effects of fennel seed and its hydroalcoholic extract on the serum total antioxidant capacity (TAC) and folliculogenesis in offspring exposed to either of the treatments in utero and 56 days after birth (PND 56). Methods Pregnant NMRI mice were randomly divided into 5 groups of 7: extract-treated groups received 500 and 1000 mg/kg/day fennel extract (FE), seed-treated groups received 500 and 1000 mg/kg/day fennel seed (FS), and the control group (CTL) received no treatment. The treatments started from pregnancy day 1 and continued until PND 56. Body and right ovary weights and ovary dimensions were recorded. Hematoxylin and eosin stained ovary sections were prepared to calculate the proportion of different follicles. The level of TAC in the serums was also measured by fluorescence recovery after photo bleaching. Results A marked rise in the body and ovary weights of treated mice was observed compared to the CTL group. The mean number of primordial, primary, pre-antral, and pre-ovulatory follicles as well as corpus luteum size in the treated offspring was significantly higher compared to those of CTL offspring. The atretic follicle number was nonsignificantly lower in either of the treatment groups compared with that in the CTL. However, treatment of animals with 500 mg/kg FE showed a more pronounced effect. Animals in FS500, FE500 and FE1000 groups had a significantly higher level of serum TAC compared to the CTL group. Conclusions Fennel extract and seed administration in pregnancy and lactation period improve offspring’s folliculogenesis. Higher level of TAC in the serum of offspring might have positively altered the folliculogenesis milieu.

Stearoyl Coa Desaturase

The effects of linseed feeding on the stearoyl-CoA desaturase (SCD) activity were evaluated on grazing dairy goats divided into two homogeneous groups (C, control, and L, treated) fed the same amount of concentrate which, for group L was supplemented with linseed. Milk yield was unaffected by the treatment. Group L showed significantly higher milk fat (4.10% vs 2.94%, p < 0.01) than group S. Within milk fatty acids, group C showed significantly higher levels of saturated fatty acids and lower values of mono-unsaturated and polyunsaturated fatty acids. In group L, total CLAs were higher than in group S (0.646% vs 0.311%; p < 0.01) mainly because of the differences in CLA cis9 trans 11 (0.623% vs 0.304%; p < 0.01). In treated animals, SCD activity, measured as cis9 C14:1/C14:0, was lower than in the control group, mainly in July and August.

Background and Aim: Alpha-tocopherol supplementation influences milk yield, milk quality, and udder health of dairy cows, which needs to be investigated for Jersey crossbred cows at hot-humid climate. Therefore, the present study was framed with an objective to study the effect of pre and postpartum Alpha-tocopherol supplementation on milk yield, milk quality, and udder health status of Jersey crossbred cows at tropical climate. Materials and Methods: For this study, 19 similar parity, body condition score, and production level dairy animals were separated randomly into three groups, namely, Control, T1 and T2. Control group (no supplementation) was compared with two treatment groups, namely, T1 and T2. Supplementation of Alpha-tocopherol was done in concentrate fed to the animals (at 1 g/cow/day) 30 days prepartum to 30 days postpartum in T1 and 30 days prepartum to 60 days postpartum in T2 groups. Observations were taken for different parameters up to 5 months of lactation. Results: Statistically analyzed data revealed that overall significantly (p<0.01) more milk production was found in T2, followed by T1 than the control group. Overall significantly (p<0.01) lower somatic cell counts and modified California mastitis tests were recorded in T2, followed by T1 than the control group. Overall significantly (p<0.01), better milk quality in terms of methylene blue reduction test was found in T2, followed by T1 than control groups. Differences in the milk composition of all three groups were non-significant (p>0.05). Conclusion: Supplementation of Alpha-tocopherol during prepartum to initial lactation period may enhance milk yield, milk quality, and udder health status of Jersey crossbred cows at the tropical lower Gangetic region.

Orange Pulp

Dried orange pulp (DOP) can be incorporated into ruminant diets, but no reports have considered this strategy during the entire lactation period in goats. Two experiments were performed using lactating Payoya goats. In experiment 1, to study the effect, over 180 days, of DOP on milk yield and composition, blood metabolites and economic values, 44 primiparous goats were allocated into three groups: control diet (concentrate plus lucerne) and DOP40 and DOP80 diets, in which DOP replaced 40% and 80%, respectively, of the cereals. Nutrient digestibility and rumen fermentation were also studied (experiment 2). The DOP diets did not affect milk yield and composition. DOP triggered lower intake and digestibility of ether extract and crude protein. Ruminal fermentation was unaffected by DOP, except for a decrease in butyrate for DOP80. The energy balance was unaltered by diet while the balance and retention of nitrogen decreased. Regarding plasma biochemistry, DOP supplementation caused changes that could indicate an improvement in hepatic function and reduced muscular damage and oxidative muscular stress. Moreover, DOP80 provided a profit increase of EUR 3.27/goat. In conclusion, the partial replacement of cereals by DOP is a profitable and healthy nutritional strategy in dairy goats and is suitable for the entire lactation period without compromising productivity.

The effect of Moringa oleifera essential oils supplementation on milk quality and fatty acid profile was studied in Sicilo-sarde sheep. Twenty-four Sicilo-Sarde ewes were divided into three homogeneous groups (8 animals per group): the control (C), O-M1 and O-M2 groups. The control group (C) received a basal diet of oats hay with complementation to the reason of 500 g/ewe/day of concentrate feed. While, ewes of the experimental batches (O-M1 and O-M2) received further to the basal diet and concentrate, 0.3 ml and 0.6 ml of Moringa oleifera essential oil (EO), respectively. The performance of the milk has been assigned (P less than 0.01) by the incorporation of essential oils (EO) of Moringa oleifera and the dose. The Fat content was significantly high (P less than 0.01) in favor of the group O-M2, while the protein content was statistically comparable (P>0.05) for the three groups. The concentration of urea nitrogen of the milk has been affected by the presence and the dose of EO of Moringa oleifera (P less than 0.01) in favor of the control group. Milk saturated fatty acids decreases (P less than 0.01) with the dose of EO, while PUFA, CLA and UFA/SFA were higher for the group (O-M2) (P less than 0.01). The supplementation of the essential oils of Moringa oleifera has improved milk production and quality of Sicilo-Sarde ewes during lactation period.

Abstract The study was conducted to determine whether the inclusion of algae Chlorella vulgaris in dairy goats’ diets would change the fatty acid profile and increase the proportion of unsaturated fatty acids in goat’s milk. White short-haired dairy goats on 2nd and 3rd lactations were fed 5 and 10 g of dried algae supplementation for six weeks. The fatty acids profile of milk was analyzed using gass chromatography (flame ionization detector (FID)). The addition of dried algae caused changes of the profile of fatty acids in the milk. The more algae were added to the diet, the greater the changes in the fatty acids profile of milk were found. A statistically significant effect (P = 0.0390) was found between the control group and the group supplemented with 10 g of Chlorella vulgaris per goat per day. The greatest effect of dietary treatment was seen in the relative reduction of palmitic acid content and increased oleic, linoleic, and linolenic acids content. Results suggested that the addition of algae also increased the nutritional quality of goat’s milk. There was a positive change in the ratio of SFA:MUFA:PUFA in terms of reducing the proportion of saturated fatty acids, as well as a change in the ratio of n-6 and n-3 PUFAs

Zahter is a traditional product for breakfast containing seeds of watermelon and melon, roasted chickpea, sesame, thyme, cumin, black cumin, fennel, coriander, anise, bulgur, koruk (dried unripe grape), citric acid, sumac, hot red ground pepper and salt although it varies from one factory to another and rely mainly on small scale home productions. All or some of the above mentioned ingredients are mixed and milled at different ratios and served as powder. It is consumed together with natural olive oil making it more attractive with respect to nourishment and health aspects. The objective of this study obtained a functional product which is ready to spread on bread by mixing olive oil, olive oil-turpentine oil and olive oil-turpentine with zahter. There were three products in different ratios. First the ratio of zahter: olive oil in the emulsion was 69:31. Second the ratio of zahter:olive oil, turpentine oil in the emulsion were 69:20:11. Third The ratio of zahter:olive oil, turpentine in the emulsion were 52:17:31. When compared with simple zahter, antioxidant capacity, phenolic compounds of each combination were higher. Furthermore it is thought that these combinations have has the effect of synergy for fat-soluble vitamins (A,D,E,K) because they contain olive oil especially and turpentine oil. According to the results of sensory analysis done, panelists gave the highest score for second emulsion which contained zahter, olive oil and turpentine oil and the lowest score for third emulsion which contained zahter, olive oil and turpentine.
