Genetic analysis of milking ability in Lacaune dairy ewes

Udder Morphology and Machine Milking Ability in Dairy Sheep

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...

Physiologic Factors That Modify the Efficiency of Machine Milking in Dairy Ewes

Machine milking efficiency can be summarized as the recuperation of the maximum amount of milk in the shortest amount of time without causing harm to the udder and without any intervention by the milker. This is to say that once the teat cups have been placed on the dairy ewe, the milking machine should be able to quickly remove all of the secreted milk that has accumulated in the udder. Failur...

Dose response of lactating dairy ewes during suckling and milking to bovine somatotropin.

The objectives were to determine the effect of administering recombinant bovine ST (bST) every 14 d on milk yield and milk composition in dairy ewes and to assess the possible effects of treatment on milk yield loss that occurs at lamb weaning. Seventy-two lactating dairy ewes were separated into 4 groups at lambing, and each group received no bST (control) or 40, 80, or 120 mg of bST every 14 ...

Comparison of external udder measurements of the sheep breeds Improved Valachian, Tsigai, Lacaune and their crosses

Morphological udder traits have recently become of greater interest from farmers to researchers. In dairy ewes, the udder is very important due to its physiological and conformational characteristics. External udder traits were measured in ewes (Ovis aries L.) of nine genotypes (355 ewes) created of the basis of Improved Valachian (IV), Tsigai (T), and Lacaune (LC) breeds (six traits; 1185 data...
