DIMOVA, N., I. IVANOVA, M. MIHAILOVA, N. TODOROV and N. NAYDENOVA, 2009. Wheat distiller’s grains as a source of protein in dairy sheep. Bulg. J. Agric. Sci., 15: 574-582 The aim of the experiment was to test a simple and cheap system of ewe feeding with forages supplemented with dry distiller’s grain with soluble (DDGS), as a source of protein and whole grains, as the source of energy, compare...

The aim of this study was to examine the expression patterns of SREBP-1 gene in milk somatic cells and its association with milk fat yield during early lactation in Sarda breed sheep. A sample of 20 Sarda ewes, aged between 4 and 5 years, in their third to fourth lactation were chosen. From each ewe 28 days after lambing milk yield was measured, and a 160 ml milk sample for the RNA extraction a...

Background: Mastitis in sheep caused by Staphylococcus spp. is a serious concern for dairy farming. Aims: The objective of this study was to evaluate the impact of the intramammary infection (IMI) caused by Staphylococcus spp. on the long-chain fatty acid profile and composition of ewe’s milk. Methods: The experiment was conducted in a herd of Zoslachtena Valaska sheep. Half-udder milk samples ...

The objective of this study was to investigate the influence meteorological and other factors on quality quantity milk Spanish Churra sheep breed, based an analysis 359,808 controls from 9,904 ewes 15 farms in 8 years. Daily yield (DMY), fat, protein, lactose (%), somatic cell count (SCC) data were obtained monthly alternating controls. Mean, maximum, minimum temperatures (T) (°C), mean relati...

Control of milk composition is of importance in dairy ewes because milk is mostly used for cheese making. Besides numerous factors that alter milk composition, knowledge on the effects of nutrition is useful for it concerns both yield and milk content. Furthermore, modification of nutrition is a powerful and short-term means of altering milk composition. Global effects of nutrition are to be se...

Iodine deficiency can impair the reproductive performance of livestock and affect perinatal mortality of offspring, yet diagnosis of deficiency is complicated and guidelines for I supplementation are imprecise. We challenged pasture-grazing pregnant ewes with a long-acting I supplement and a goitrogenic forage, then monitored their I status during gestation and lactation and in their lambs from...

The aim of this research was to enhance the nutritional quality of ewe milk fat by increasing potentially healthy fatty acids (FA) through diet supplementation with unprotected oil rich in linoleic acid, and without detrimental effects on animal performance. Twenty-four ewes were assigned to two high concentrate diets, control or supplemented with 6% sunflower oil (SO), for 4 weeks. No differen...

This paper describes the particularities of the anatomy and morphology of the dairy sheep udder and the current implications on machine milkability. The sheep mammary gland is an exocrine epithelial gland mainly constituted of tubulo-alveolar parenchyma with alveoli and well differentiated cisterns. Two anatomical compartments are used for milk storage: alveolar and cisternal, the large-cistern...
