| Popis: | We have shown that dietary supplementation of n-3 polyunsaturated fatty acid (n-3 PUFA)-rich fish oil (FO) around the breeding time improved the utero-ovarian functions in the goat. Here, we investigated the effect of FO supplementation during the periparturient period on serum n-3 PUFA, prostaglandin F2α metabolite (PGFM), placental expulsion, uterine involution, resumption of oestrus and neonatal vigour. Rohilkhandi goat in advanced gestation (n = 16) was divided into two equal groups. One group was supplemented with FO containing 26% n-3 long-chain PUFA at the rate of 156 mg per kg body weight, while the control group was fed isocaloric palm oil (PO) from -3 to +3 week of kidding. Dietary FO increased serum concentration of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) by 7.3- and 6.6-fold, respectively, after 6 weeks of supplementation. Goats in FO group expelled the foetal membranes 99.1 min earlier (p < .01) than those of PO group. Further, dietary FO significantly decreased the serum PGFM on day 7 post-partum. However, no difference was found on uterine involution, which was complete by day 20 post-partum in either group. Resumption of follicular activity by day 5 post-partum was 87.5% in the FO as compared to 25% in the PO group (p < .05). Similarly, occurrence of behavioural oestrus by day 90 post-partum was 57.1% in goats of the FO group while none of does was in the PO group (p < .01) expressed oestrus. It was concluded that feeding FO-rich diet during -3 to +3 weeks of kidding decreased the PGFM till day 7 post-partum, hastened the expulsion of foetal membranes and reduced the time from kidding to first post-partum oestrus in Rohilkhandi does. |
