| Abstract | ||||
| The current study was undertaken to evaluate the physiological responses and productive performance of rabbit does as impacted by hydrolysable tannins (HT) and/or grape seeds extract (GSE) supplementation. A total number of 36 pregnant NZW rabbit does were used. They divided into four equal groups. The first group (G1) fed the basal diet without any supplementation and served as a control group. The other three groups were fed the same basal diet and supplied with HT at rate of 1.5 g/kg diet (G2), GSE at rate of 0.5 g/kg diet and a combination mixture of both supplements at the same rates (G4). Hormones, lipids and antioxidants capacity were quantified at days 14, 21 and at kindling day. Does performance was determined at mating, peak of lactation and weaning age. Litters performance was recorded at days of birth, 7, 14, 21 and weaning age. The present results revealed that, the highest levels of P4 and E2 were observed in G1 at day 14 and in G4 at day 21. Meanwhile, the lowest values of both hormones were noticed in G4 at kindling day. Does in G3 showed the lowest values of both TG and TC compared to the other treatments. All treatments were succeeded in improving the antioxidant capacity than that of G1, by lowering MDA values and increasing GPx activities. Daily milk yield increased in G4 than the other groups. There were no significant differences in does BW among all groups at different ages. Values of litters size and weight were lowest in G3 and highest in in G4 during the whole experimental period. In conclusion, the present results proved that all treatments were succeeded in improving both physiological responses and productive performance of pregnant does. Supplementing does with both HT and GSE together was the best and beneficial treatment followed by HT compared to control group. In conclusion, it was obvious the benefits of using the mix between TH and GSE via the enhancement in antioxidant status, milk production litter size and weight. But it should use it carefully in order to maintain P4 hormone level to complete pregnancy period safely. | ||||
