The objective of the present study was to examine the effect of dietary n-3 PUFA supplementation on oestrus response in the goat following synchronization with prostaglandin analogue. Parous cycling goats (n=17/group) were fed a concentrate diet supplemented with either fi sh oil (FO) or palm oil (PO). The FO provided n-3 EPA and DHA @ 156 mg kg-1 body weight while PO was given @ 0.6 ml kg-1 bo...

The strategic use of natural shade and iodine supplementation at the time of joining led to an improved fertility of tropical Merino ewes. This was most pronounced when ambient heat stress was greatest (p <O.Ol). A higher incidence of oestrus and a higher pregnancy rate in mated animals both contributed to the improved fertility. Heat' stress conditions experienced during summer in a tropical s...

A dose determination study for the prostaglandin analogue cloprostenol was conducted in the Red Sokoto Does (RSD). 24 RSD were divided into four groups of 6 animals, the first group is the untreated control receiving 0μg of the cloprostenol. The second, third and fourth groups were given 50μg, 75 μg and 100 μg of the drug respectively. No oestrus response was observed in the control. All the an...

The effectiveness of CIDR-B treatment for 12 days compared with the double injections of cloprostenol for oestrus synchronization in Kedah-Kelantan (KK) cows was evaluated. A total of 148 KK cows were used in three trials conducted at MARDI Research Station, Kluang, Johor. Cows were allocated randomly into two groups. Group 1 was given two injections IM of cloprostenol at 12 days apart; group 2...
