The objective of this work was to estimate milk production through hand milking, using different doses (1; 2; 3; 4; and 5 IU) of oxytocin intramuscularly. Ten adult Hampshire Down ewes were assigned to a 5 x 5 repeated Latin square design, with five ewes and five days. Milking was performed after a 4-hour lamb separation period, and then corrected to 24 hours. On the last day of estimation, the ewes were milked at four different times, 12:30 p.m.; 06:30 […]

The aim of the experiment was to evaluate the effect of two stocking rates (CA280= 280 kg and CA360= 360 kg of live weight/ha) on natural pasture and of two breed compositions (½ Nelore ½ Hereford and ¼ Nelore ¾ Hereford) on milk production of primiparous beef cows and on growth of their calves. The stocking rate did not affect milk production (CA280 = 6.16 and CA360 = 5.88 kg/cow/day). Breed composition of cows significantly affected milk production, with ½ […]
