Comparison Of Reproductive Efficiency Of Beetal Goats In Different Management - 2008

The present study was conducted at two fanns (1) NH goat fann at Raiwind and (2) BN at Okara. The study consist the reproductive efficiency of beetal goats in different management systems. In this study we compared two management systems of goat production i.e. (1) seasonal (2) year round breeding were compared on the basis of reproductive efficiency and growth parameters, moreover cost effectiveness of the both systems were compared on the basis of their outcomes.
In this study, reproductive and productive parameters of n = 72 adult goats + 2 bucks in each flock were collected and analyzed. Data regarding pubertal and twinning of their progeny born during a period of a year were collected and compared. Goats of same breed and comparable ages and body weight, body condition scoring were used in this study. Study was carried out at similar period of time for one year.
The conception rate was higher at NH than BN goat fann. It was 0.809± 0.058 in BN and 0.88 ± 0.066 in NH respectively. The birth weight of male and female kids ofBN fann was higher than NH kids. It was (3.824 ±0.083 kg) in BN kids (3.513 ± 0.20 kg) in NH kids respectively. While the weight of female kids were (3.503 ±0.083 kg) in BN kids and (3.456 ± 0.10 kg) in NH kids. The age at puberty was higher at BN (245.3 ± 2.9 days) than NH goat fann (242.4 ±1.9 days). The kidding interval at BN was higher than NH flock. It was (314 ± 20 day) and (224.8 ± 0.915 days) days respectively. The post partum anestrous exhibited only in NH does, because in this fann the buck was free all around the year and after (50.0± 3.95 days) the does mate if they are in estrous, while in BN fann, bucks were free during the season. The body condition scoring (1-5 point) was higher in NH goats (2.44 ± 0.14) than BN goat fann (1.91 ± 0.11). The Body weight of does between both flocks were higher in BN (42.47 ± 0.92) than in N H goat farm (41.10 ± 1.9). The high concentrate feeding intake between two farms showed that the concentrate feed intake was higher in BN 491.5 ± 8.5 gm per day per goat than N H goat farm (146 ± 30 gm per day.
It is concluded that the reproductive efficiency of Beetal goats in N H goat farm was higher than BN farm~ because the seasonal breeding at BN has limited the kidding frequency. Where as~ all year round breeding was efficient and the kidding distribution almost doubled in the same year. The cost of feeding was higher in BN than NH goat farm~ because they provide concentrate daily~ but the cost of labour and miscellaneous was higher in NH than BN goat farm. The management of feeding~ green fodder was higher and there were sufficient green fodder for whole year in NH goat farm. The reproductive performance of Beetal goats can be improved by good managemental systems and all year round breeding.
Research and development efforts can significantly improve reproductive efficiency of goats and simultaneously enhance the livelihood of the poor. Structuring the whole system via adapted reproductive techniques (thus allowing high levels of productivity). Findings of this study would be useful to determine the viability of systems on the basis of reproductive efficiency and may provide basic guidelines to establish goat farms in the future.
