Sažetak

Milk production in sheep seem to be related to lamb weight at birth. This is probably due to the lactogen placental hormone whose secretion depends on the weight of the placenta. 4 experimental trials were carried out, 2 on Sarda ewes (S) and 2 on Merino (M) and Awasi x Merino (A x M) ewes, during the period between 5-th and 8-th week post partum. Data of body weight of ewes, weight at birth weight of lambs and milk production were collecteds. Linear regresion analysis between grams of lamb at birth per kg of ewe's body weight and grams of milk produced per kg of ewe's body weight show that the two variables are positively correlated and that milk removal by twin lambs increased milk yield.
