Twenty-four Saanen goats (15 multiparous and 9 primiparous) from 21 days prepartum to 200 days in lactation were used to evaluate milk yield and composition. Animals were randomly distributed in a 3 × 2 factorial arrangement (3 diets × 2 parity orders) and fed a 40:60 forage:concentrate diet composed of soybean meal, soybean meal + dry yeast or dry yeast as protein source, plus ground corn, mineral supplement and corn silage. The protein source did not influence the body weight […]

This study aimed to identify some performance parameters associated with the farrowing efficiency in sows. From a total of 636 births and 7,100 piglets born, data was collected for: parity (OP), number of piglets born alive (NV), stillborns (NAT), mummified (MUM), total litter size (TN), use of vaginal palpation and oxytocin injection, time of birth for each piglet, and beginning and end of the parturition. The average interval among piglets birth was 16.7 min and the average duration of parturition […]
