Jersey, Friesian (Fr) and Dutch Red and White (DRW) dairy cows were treated over three lactations with BST, recombinantly derived bovine somatotropin (somidobove), in a sustained-delivery vehicle injected subcutaneously once every 28 days. In the fir

The influence of bovine somatotropin (bST) and two levels of rumen-degradable protein on milk production and composition was investigated in 42 cows. The treatments were given in a factorial design from approx. 9 to 25 weeks post-partum, following a

Twelve trials designed to test the effect of monensin on milk production were carried out at eight different research farms. Data from these studies were evaluated for effects of monensin on health and reproduction. Monensin was added to the concentr

We examined the effects of monensin on feed intake and milk production in Holstein-Friesian cows receiving a total mixed rations in two experiments. In experiment 1, 60 individually fed cows consumed, during wk 7 to 26 of lactation, 1 kg/d of supplem

Effects of the administration of monensin via concentrates to dairy cows were studied in two trials. In one trial, 64 Holstein cows were assigned to four groups that received 0, 150, 300, or 450 mg/d of monensin from 5 to 24 wk postpartum. Milk produ

Jersey, Dutch Red and White, and Friesian cows were subcutaneously injected with 640 mg of recombinant bST at 28-d intervals from 87 to 115 d after calving through four successive lactations. A TMR (6.72 MJ of NEL) and 168 g of CP/kg of DM) was fed f

After calving 16 Friesian, 16 Jersey and 16 Dutch Red and White cows were taken into a 252-day experiment to determine the response in milk production, body weight and feed intake to the administration of somidobove (recombinantly derived bovine soma
