The objective of this study was to record certain physiological serum chemistry variables viz. Sodium (Na+), Potassium (K+), albumin (ALB), Alanine Transaminase (ALT), Aspartate Transaminase (AST) and Gamma Glutamyl Transferase (GGT), and Brix % (by Brix refractometer) for assessing the status of passive transfer in goat kids (n=26) of Dera Ghazi Khan district, Punjab, Pakistan. The blood samples were collected during January to April, 2018. The kids were divided as per breed (teddy and cross-bred), gender (male and female), age (1-4 days, 5 days, and above 5 days) and parity (1st, 2nd, 3rd and >3). The overall mean (±SE) values for Na+, K+, ALB, AST, ALT and GGT were 82.5±2.2meq/L, 5.0±0.5meq/L, 2.8±0.2U/L, 1444.4±32.1U/L, 735.1±32.3U/L and 223.0±3.7U/L, respectively. Overall mean Brix% value was 11.2±0.9% which coincided with IgG level of 43.25g/L. Only Na+ and K+ were different within teddy and cross-bred kids being higher (P≤0.05) for the latter. Mean Brix% values for cross-bred and teddy were 10.9±0.2 and 11.6±0.3%, respectively coinciding with IgG values of 40.2 and 46.6g/L, respectively. The IgG level decreased as the kids got older, though non-significantly (P ≥0.05). Regarding correlation coefficients, K+ was negatively and ALT was positively correlated to estimated IgG at P≤0.05. In a nutshell, results of our study indicate that teddy and cross-bred goat kids have substantial circulating IgG levels. Furthermore, the study caters for the first time the physiological values for various chemistry attributes, Brix% and calculated IgG levels for cross bred and teddy breed of goats. A substantial correlation between these has also been ascertained.
