We conducted the study to evaluate the physiological and hematological responses of pregnant Sapera dairy goats on feeding and drinking limitation. Four pregnant Sapera dairy goats were used in a 4 x 4 Latin square design with four feed regimens: group A feeding was in the form of concentrate and elephant grass silage as much as 1400 gr/ day, group B was 1000 gr/day, group C was 700 gr/day, and group D was 500 gr/day. Drinking water was given only for 2 hours from the feeding schedule. The results showed that the physiological and hematological responses of the four groups were in normal condition despite experiencing feeding and drinking limitations. Physiological responses showed differences at several observation points, however pregnant Sapera dairy goat was able to restore thermal balance to the body with no difference in the hematological parameter in the four groups. This shows that the pregnant Sapera dairy goat had adaptive abilities even though it was subjected to feeding and drinking limitation.
The Belgian Blue cattle were imported to Indonesia for increasing beef production. A preliminary study was done to know the birth weight and pre-weaning mortality of BB calves from some recipient dam breed in different altitude. About 86 records of Belgian Blue purebred calves resulted from embrio transfer were used in this study. Data of birth weight were analysed using general linear model with recipient dam breed, altitude and sex of calf as fixed effect. Data of mortality were analysed using chi-square for different altitudeThe birth weight were significantly affected by recipient dam breed and altitude (P<0.05), but not sex of calves (P>0.05). Birth weights were 44.44±1.68 kg, 40.58±2.71 kg, 50.53±1.12 kg, 50.85±1.62 kg and 55.56±1.21 kg for Brahman, Ongole grade, Simental, Limousine and Friesian Holstein (FH) recipient dam, respectively. The birth weights were 43.09±1.46 kg, 51.11±0.92 kg and 54.18±1.29 kg for upland, middleland and lowland areas, respectively. The pre-weaning mortality were affected by altitude (P<0.05). The percentage of mortality were 61.1%, 22.3% and 41.9% for upland, middle land and lowland, respectively. The study concluded birth weight of BB purbred calves were highest in recipient dam of FH. BB calves performed better in middle land and above based on higher birth weight and lower mortality. This result was a preliminary study used as a recommendation in developing Belgian Blue cattle in Indonesia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
