ABSTRACT
The study was carried out to investigate hemato-biochemical profile and blood metabolites during different periods of pre-pubertal growth in summer- and winter-born black Bengal kids of either sexes. The body weight was 8.07 ± 0.21 kg on 180 day with significantly (P < 0.01) higher growth in male kids. The winter born kids exhibited significantly (P < 0.01) higher body weight, packed cell volume (PCV), hemoglobin (Hb), total leukocyte counts (TLC), glucose and cholesterol and significantly (P < 0.01) lower non-esterified fatty acids (NEFA) and α-amino nitrogen (AAN). Both PCV and Hb were lowest on day 15 and then increased significantly (P ≤ 0.01) and reached maximum value at 90 days (PCV) and 180 days (Hb). TEC increased significantly (P ≤ 0.01) from day 15 to 180 days and reached its maximum value at 180 days age. Both glucose and total cholesterol were maximum at day 15 and significantly (P ≤ 0.01) decreased with the advancement of age and found lowest was at day 150. But, total protein was lowest at day 15 and increased significantly (P ≤ 0.01) up to day 150. NEFA and AAN were lowest on day 15 and increased significantly (P ≤ 0.01) with the advancement of age and reached peak value on 180 days.
