The pattern of immunoglobulin and Physico-chemical composition of goat (Capra hircus) colostrum

Abstract:

Colostrum composition of 20 primiparous local Pantja goat were evaluated and there was a slight increase in the pH of colostrum from 0 hr. to 64 hr. (i.e. from 6.63±0.078 to 6.88 ±0.027). After that, there was a decrease in pH values. Conductivity values of colostrum also showed an increasing trend. The specific gravity of colostrum showed a decreasing trend from parturition to 96 hr. post-partum. A decreasing trend was also noted for IgG and fat content. Maximum IgG concentration was at 0 hr. (75.52±1.421 mg/ml) while minimum IgG content was noted at 96 hr. post-partum i.e. 36.38 ±1.163 mg/ml. Maximum fat content was at 0 hours (9.57 percent) while minimum fat content was noted at 88 hours post-partum (3.5 percent). The total solids content of colostrum followed the decreasing trend. The maximum total solids content of colostrum was found at 0 hr. (i.e.23.45±0.949 percent) while minimum content was found at 96 hr. (i.e. 12.48±0.303 percent). SNF content of colostrum also showed a decreasing trend. Maximum and minimum SNF content of colostrum were estimated at 0 hr. and 88 hr. (i.e. 14.23±0.519 and 8.37±0.124, respectively). The protein showed a decreasing trend till 80 hr (i.e. 3.39±0.084 percent) after that at 96 hr it showed a slight increase (i.e.3.54±0.09 percent). The lactose content of colostrum had an increasing trend from parturition to 96 hr. post-partum (i.e. from 1.87 ± 0.088 to 4.14 ± 0.168 percent) while there was a decrease in ash content of colostrum as time passed from 0 to 96 hr. The highest and lowest values of ash content were recorded as 2.01±0.175 percent and 0.75±0.018 percent at 0 hr. and 88 hr. respectively.
