| Abstract | ||||
| The present study aimed to investigate the effect of different injection levels of selenium plus vitamin E on goat performance, intake, digestibility, nutritive value and body weight of kids. Forty Baladi doe goats 2-3 year old and (20.47±1.82 kg) average live body weight were randomly divided into four groups (10 does each). The first group was a control group, does of 2nd, 3rd and 4th groups received two injections of selenium and Vit. E; at early and late periods of gestation as follows, 0.125 mg Se+ 1.7 IU Vit. E/kg BW for 2nd group (T1), 0.250 mg Se + 3.4 IU Vit. E/kg BW for 3rd group (T2) and 0.310 mg Se + 4.2 IU Vit. E/kg BW for 4th group (T3). Digestibility trials were carried out after each injection. Does were fed a basal ration of concentrate feed mixture and the roughage portion of the diet was Berseem hay. Body weight of dams and kids were recorded. Results revealed that, the injection of both Se and Vit. E did not show any significant effects on TDMI and CPI of treated groups at either period of pregnancy. Control group showed higher (P<0.05) CPD% than treatments. Whereas, EED% was increased with Se supplementation. Supplementation of Se and Vit. E increased TDN% at late period and decreased NB at early and late pregnancy compared to control. Supplementation increased weight gain during pregnancy. Control and T2 recorded higher (P<0.05) average weaning weight, and daily gain than T3 and T1 groups. It could be concluded that lower level (0.125 mg Se plus 1.7 IU Vit. E/ kg /kg BW) injection during early and late gestation improved nutrients digestibility, nutritive values, nitrogen utilization | ||||
