EFFECTS OF FOCUS FEEDING WITH VITAMIN AD3E INJECTION ON PERFORMANCES IN JAMUNAPARI GOATS

Abstract

The present study was conducted in a goat farm to adopt the strategies for focus feeding and observe the effects of focus feeding with Vitamin AD3E injection on reproductive performances and milk yield in Jamunapari goats. For this study, 30 clinically healthy does were used. All experimental goats were assigned into two groups as Group I and Group II. The goats of Group I were maintained on natural grazing with traditional feeding practice. While goats of Group II were supplemented with concentrate feed along with natural grazing and also vitamin AD3E injection. The supplements were given from 45 days before mating time up to 45 days after kidding. Vitamin AD3E was injected at every alternative day from 30 days before kidding up to kidding. There was no significant difference (p>0.05) in duration of estrous in indigenous does between two group. The observed duration of estrous was 46 ± 3.09 and 43 ± 3.82 hours respectively. Highest pregnancy rate (100%) was observed in does of Group II compare with Group I (86.67%). Though there was no significant differences (p>0.5) in gestation length between two groups, Group I goats showed slightly higher (143.3 ± 1.7 days) value than Group II (142.7 ± 2.7 days). Significantly (p<0.05) higher litter size was found in Group II (1.93± 0.7) than Group I (1.27±0.7). Significantly higher (p<0.5) kidding rate was observed in does of Group II (100%) compared with Group I (86.67%). Single kidding rate was higher (46.15 %) in Group I than Group II (26.67%). Twinning kidding rate were higher in Group II than Group I. Triple kidding rate were observed 7.69 % in Group I and 6.67% in Group II. Quadruple kidding was only observed in Group II (6.67%). Average daily weight gain in kids of Group II was significantly (p<0.01) higher than kids of Group I (0.0733±0.0076 Vs 0.0359±0.0205). Infertility rate was higher (13.33 %) in Group I than Group II (0%). Kid survival rate was significantly (p<0.05) higher (100 %) in Group II and 57.14 % in Group 8 I. The post partum onset of estrous was significantly shorter (p<0.01) in goats Group II (46 ± 0.5 days) than controlled group (78.8 ± 9.17 days). Average milk production was higher in Group II (946.12 ± 146.3 ml) than Group I (535.5 ± 138.3 ml). It could be concluded that focus feeding before breeding along with vitamin AD3E injection is effective, safe and practical technique and it may be used for improving reproductive performance of does, preventing mortality and increasing newborn vitality and increasing milk production. Further work involving large number of animal should be needed.
