Progestagen is generally used for hormonal treatment in the synchronization program, but the cost of this stuffs is relatively expensive. An alternatif low cost agent for sinchronization is needed and this is a focus of the present study. Forty eight heads of mature does and 4 bucks of Peranakan Etawah (PE) goats was used in two phases of study. In the first phase, three types of composite compounds (TOP-A, TOP-B and TOP-C) were tested on a number of PE does. In the second phase of the study, the best TOP composite of the first phase was compared with Fluogestone Acetate (FGA) which is a commercially made of progestagen for synchronization. FGA was inserted intravaginal for 7 days (FGA-7) and 14 days (FGA-14). Results of the study in phase I showed that only 40-60% of does showed oestrus following TOP composite treatment, and 50-67% of them in groups TOP-A and TOP-B did not ovulate, while all oestrous does in TOP-C group ovulated. Oestrous cycle length was within a normal range of oestrous cycle (15 - 22 days) indicating that TOP composite did not have negative effect on reproductive activity of goats. The best TOP-C in the study phase I was tested in the study phase II and compared with FGA. The results showed that the number of does in oestrus in TOP-C group was only 63.6% which was much lower than those of FGA-7 (81.8%) and FGA-14 (100% ). Imperiority of TOP-C and FGA-7 were shown by a relatively high incident of oestrus without ovulation which were 14.3% and 11.1% for the respective groups. Consequently, ovulation rates in both groups were lower than those of FGA-14 (1.1 vs 1.4 vs 1.8, P<0.05). Pregnancy rate in TOP-C was also the lowest (27.3%) compared with those of group FGA-7 (63.6%) and group FGA-14 (81.8%). Based on the results obtained, it could be concluded that TOP composite used in this study was not as good as FGA in inducing oestrus in goat.

Naturally, progesterone in ruminant is mainly produced by corpus luteum and it is reponsible for maintaining pregnancy, and affecting udder development and milk production. Exogenous progesterone treatment is expected to give similar positive effect on milk production as the endogenous progesterone does. Fourty mature Etawa grade (PE) does were synchronized for oestrus using Controlled Internal Drug Release (CIDR) followed by natural mating. Does then were treated with CIDR intravaginally, as a source of exogenous progesterone, at day 15-75 after mating (Group A), day 75-135 after mating (Group B), and without exogenous progesterone treatment (Control). Blood samples were taken before and after exogenous progesterone treatment for determination of progesterone concentrations. Soon after birth, kids were separated from their respective dams and they were milk fed through milk bottle. Feed consumption and milk production were measured daily, while bodyweight was measured forthnightly. Results showed that response of does following exogenous progesterone treatment was not expressed by an increase in progesterone concentration in the blood plasm. However, treatment group showed kid with birthweight of 10-13% higher compared to Control Group. In relation to milk yield, birthweight and pre-weaning growth of kids, the positive responses of exogenous progesterone treatment were not significant, though there was a substantial decrease (71.2%) in pre-weaning kidâs mortality.

The experiment was conducted to evaluate growth and sexual development of female Etawah-cross kids of the progeny of the does with low (Group L), medium (Group M) and high (Group H) milk production. The does were fed King grass (Pennisetum purpureophoides) (about 2% DM of liveweight) and 400 g/head of concentrate. The amount of concentrate was increased to 600 g/head during the last two months of pregnancy period and during lactation. Kids were weaned at four months of age. Thereafter, they were reared in group and were fed King grass and concentrate. The animals were weighed every two weeks. A mature vasectomized buck were joined in each group to detect the onset of first oestrus (puberty). When kids reached puberty and had a liveweight of about 20 kg, they were mated with intact buck. Ovulation rate, progesterone profiles and fertility were observed. The results showed that pre-weaning growth rates of kids in all three groups were not significantly different (67.0 vs 74.9 vs 70.5 g/day, P>0.05). At six and 12 months of ages, Groups L and M had almost the same liveweight which were higher than Group H. Consequently, Groups L and M reached puberty about 3 - 6 weeks earlier than Group H. The average liveweight at puberty was 19.9, 18.2 and 18.8 kg for Groups L, M and H, respectively, or at about 57.1-69.8% (average 63.2%) of mature liveweight. The pregnancy rate following first mating was relatively high (67-73%) and all does were pregnant in the following mating. Average ovulation rate at conception were low (1.1) in all groups. It was concluded that differences in milk production of the does did not significantly affect post-weaning growth and sexual development and performances of kids. Other factors at certain age or growth phases might be more important to affect growth and reproduction of Etawah-cross goat, and this may warrant further study.
