The aim of this work was to evaluate the effect of bypass fat on milk production and composition in Bergamasca ewes. It was used 77 ewes which were distributed by parity and age orders in two groups: control diet (C): corn silage and concentrate; and bypass fat diet (GP): corn silage + concentrated + bypass fat (35 g/ewe/day) added in the concentrate. Diets were isoenergetic and isonitrogenous with 70% of total digestible nutrients and 16% of crude protein on dry […]

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 […]
