Effect of Maternal Nutrition at Different Stages of Pregnancy in Goats (Etawa Cross and Kacang) on Performance of Does and Goat Kids

Arrangement nutrients to pregnant of does (nutrition in utero) have implicated the good growth changes during prenatal or postnatal and goat kids performance. Linkage nutritional needs of does to birth weight and physical characteristics of goatling at birth and health status. Birth weight is one of the things that are important in growth patterns, because kids with birth weight heavier than the average normal weight more capable of sustaining life. The research was conducted using the animals of some small farmer holders, District Tamalatea, Jeneponto, South Sulawesi Indonesia. There were Kacang ang Etawa does goats used in the experiment, which were divided into 4 groups (1) pregnant doe early (gestation 1 to 3 months), (2) pregnant doe late (gestation 3 to 5 months), (3) pregnant doe feeding without supplements and U4 Parent bunting with supplementation during pregnancy. The animals were fed native grass ad libitum as basal diet as well as drinking water. Parameters measured were body weight of does, blood metabolites (glucose, urea and creatinine), birth weight goatling. Data were analyzed in accordance with the procedures of variance analysis. The result indicated that UMMB supplementation did improve reproduction performace of does significantly, and the optimum result indicated when UMMB was supplemented from 1 to 3 month of pregnancy age. Feeding UMMB supplements can increase weight gain pregnant does. The optimum time feeding supplements on pregnant does give high weight gain in gestation 1 to 3 months (early). The content of the blood glucose is influenced by the type of goat and gestation. High blood glucose content in the parent fed supplements during pregnancy but not different at the beginning and end of pregnancy. The content of blood metabolites (urea and kreatinine) is not influenced by gestation, and blood metabolite content is relatively higher in animals fed a supplement. Birth weight was higher in kids who were fed supplements parent at the age of 3 to 5 months of pregnancy followed the holding fed supplements during pregnancy.
