Enhancing healthy fatty acids (FAs) in ewe milk fat and suckling lamb tissues is an important objective in terms of improving the nutritional value of these foods for the consumer. The present study examined the effects of feeding-protected lipid supplements rich in unsaturated FAs on the lipid composition of ewe milk, and subsequently in the muscle and subcutaneous adipose tissues of lambs suc...

In the present study, a microbiological challenge test in artificially contaminated raw milk Pecorino Umbro cheese during cheese-making was carried out. Raw ewe milk was contaminated by a suspension of particular Listeria monocytogenes strains. The number of L. monocytogenes and L. monocytogenes dynamic growth were evaluated during cheese-making and storage. A significant decrease of the viable...

The digestible protein requirements of lactating ewes were studied with Chios 3 ewes during the declining state of lactation in two nitrogen balance and three feeding trials. A 60 kg ewe producing 1.0 or 2.0 kg milk of 6% protein and maintaining weight equilibrium, required 134 and 230 g digestible protein daily, respectively. These requirements were obtained with ewes receiving 110 Kcal metabo...

background:chronic active adrenocorticotropin hormone (acth) immunization of ewes (with a previous history of immunization) resulted in elevated titres of antibody against acth, which induced a reduction in circulating levels of cortisol. objectives:the aim of the present study was to investigate: a) the influence of active immunization against acth on milk production of the ewe as assessed by ...

Mature pregnant crossbred ewes (n = 90) were used in a randomized complete block design and assigned to 1 of 3 winter-feeding systems differing in primary feed source: haylage (HL), limit-fed corn (CN), or limit-fed dried distillers grains (DDGS). Effects of these winter-feeding strategies on ewe and lamb performance were determined. Diets were formulated to meet or exceed NRC (1985) nutrient r...

The objective of the research was to evaluate effects increasing dietary Zn sulfate concentration for primiparous gestating ewes on subsequent milk SCC, intramammary microbial identifications, and fatty acid composition. Commercial white-face (WF; n = 27) black-face (BF; 24) (age ≈18 mo; BW 87.48 ± 8.37 kg) were sorted into breed-type groups within ranked by BW, then, they randomly divided 3 su...

Three groups of ten lactating Sardinian ewes were used between 3 and 6 month of lactation to determine the effects of supplementing diets with n-3 fatty acids on milk production and milk fat composition. The control group (A) was fed on a mixture of Gramineae hay with a pelleted alfalfa and concentrate; the other groups (B and C) were given the control ration supplemented with graded levels of ...

Two / 2 East Friesian (EF), one / 4 EF, one / 8 EF, and several Dorset rams were mated to crossbred ewes from 1993 through 1996. Growth, reproduction, and lactation performance of their progeny were compared. EF-cross lambs had greater birth, weaning, and postweaning weights than Dorset-cross lambs. When lambing at one and two years of age, EF-cross ewes gave birth to and reared more lambs per ...
