Study on early milk composition and its effect on preweaning growth performance in boer goat crosses
The objective of this study was to evaluate the early milk composition values for Boer goat crosses and to identify relationship between composition of milk values with preweaning ADG (Average Daily Gain) and weaning weight in single and twin type of birth. A total of 30 samples of milk were collec...

| Summary: | The objective of this study was to evaluate the early milk composition values for Boer goat crosses and to identify relationship between composition of milk values with
preweaning ADG (Average Daily Gain) and weaning weight in single and twin type of birth. A total of 30 samples of milk were collected by hand milking. Milk composition was analyzed using a special milk analyzer, 'Ekomilk Total' which is a robust, reliable, automated multi-parameter milk analyzer and providing rapid test result. All milk composition parameters such as fat, SNF, density, protein and lactose decreased through days except percentage of fat which increased. Result showed that respective parameters except percentage of fat differed significantly (P < 0.05) over three days. The milk composition for three days post partum was negatively correlated with preweaning ADG and weaning weight for single kidding. For twin kidding, the
correlation between SNF, density, protein and lactose values with preweaning ADG and weaning weight was significantly positive (P < 0.05). Conversely, the correlations between percentage of fat with preweaning ADG and weaning weight in twin kidding were significantly negative. |
