| Abstract | ||
| Forty Zaraibi goats having 3 years old and 41 kg live body weight (LBW) were used. Goats were placed into similar five groups based on their age, body weight, (8 does / group) which the control group were fed on basal diet containing 0.17 mg Se/kg DM. The treated goats fed on the same basal diet plus the treatment with Se as follows: First group (G1): as a control group without any treatment. Second group (G2): goats were injected with 0.1 mg of selenium (sodium selenite) per kg LBW. Third group (G3): goats were injected with 0.2 mg of selenium (sodium selenite) per kg LBW. Fourth group (G4): goats were given oral dose of Nano-selenium (Na-Se, 0.1 mg/kg LBW). Fifth group (G5): goats were given oral dose of Na-Se (0.2 mg/kg LBW). Values of the percentage of does that came in estrus following treatment were significantly higher (P<0.05) in G3, G4, and G5 (100%) than G2 treatment group (87.5%), however, relatively low estrous activity for does has occurred on control group G1 (75%). In does treated with Na-Se kidding rate of the highest value in September experiment (2.25) for G4 and G5 while gradually decreased reaching 1.71 and 1.66 for G2 and G3 and the lowest value in kidding rate 1.16 for G1 (control). Does in all treatment groups (G2, G3, G4 and G5) has single birth (16.7, 14.3, 12.5 and 12.5%) compared with those in G1 significantly (P<0.05) produced more single birth (60%). However, does which have the highest value of twins birth was G2 (66.7%) with significantly differences (P<0.05), while G3, G4 and G5 have 57.1%, 50% and 50% compared with the lowest value of twins (40%) on controls (G1). Its worth to note that does which produce triples was 16.6, 28.6, 37.5 and 37.5% for G2, G3, G4 and G5. Does in all treatment groups, except those in G5 significantly (P<0.05) produced more female kids (61.1%) and less male kids (38.9%) than the other treatment or control group. The values were 42.9, 58.3, 40 and 55.5% male for G1, G2, G3 and G4, respectively. On overview, the obtained results indicated that the supplementation positively improved reproduction performance. It was concluded that Na-Se can be used as a alternatively available source in Zaraibi goats | ||
