Abstract:
The present study was conducted to study effect of rumen protected niacin supplementation on erythrogram and leukogram profile of transition Surti goats. Based on parity, body condition score and body weight, 18 pregnant Surti goats were selected and divided equally into two groups as control (CON, n=9) and treatment (RPN, n=9). Treatment group (RPN) was supplemented with rumen protected niacin (RPN) @1.5 gram/animal/day from 2 weeks pre kidding (-2 w) to 6 weeks post kidding (+6 w). At -2 week, at kidding, +2, +4, +6, +8 and +10 week of kidding, collection of blood samples for analysis of hematological parameters were done. RPN supplemented group had significantly (P≤0.05) higher TEC and Hct at 0 as well as +6 week and higher Hb at +6 week. Supplementation of RPN led to significantly (P≤0.05) lowering of neutrophil % as well as neutrophil to lymphocyte ratio at 0 week and significant (P≤0.05) elevation of eosinophil % at +4 week as well as significantly (P≤0.05) lowering of it at +8 week. Due to RPN supplementation there was significantly (P≤0.05) higher lymphocyte% at 0 week. Non-significant differences were observed for MCV, MCH, MCHC, basophil, monocyte and TLC. It was thus concluded that RPN supplementation @1.5g/goat/day in transition Surti goats improved erythrogram parameters as indicated by increased TEC and Hct at kidding and +6 weeks as well as Hb at +6 weeks post-kidding and improved immune status as evident by increased neutrophils, decreased lymphocytes and increased neutrophil to lymphocyte ratio among leukogram parameters at kidding.
