Sow Reproductive Performance in Institutional Herds in Benue State,
This study was carried out to determine the reproductive performance of sows in institutional swine herds which serve as model herds in Benue state, central Nigeria. Herd records on 185 sows that littered 3,995 piglets from three herds were used for the analysis of reproductive and production performance. Management practices including reproductive management, herd structure, breeds of sows, an...
متن کاملLow reproductive performance and high sow mortality in a pig breeding herd: a case study
Sow performance is a key component of the productivity of commercial pig farms. Reproductive failure in the sow is common in pig production. For every 100 sows served, 89 should farrow. In absence of specific diseases such as porcine parvovirus, pseudo-rabies, swine fever, leptospirosis and brucellosis, management failures are the most important causes of loss. A syndrome associated with reprod...
متن کاملReproductive productivity measurements in Japanese swine breeding herds.
To set productivity standards and targets, and investigate inter-relationships between key measurements in swine breeding herds, farm productivity measurements were analyzed on 87 Japanese commercial farms in 14 prefectures. The 87 herds were ranked on the basis of number of pigs weaned per mated female per year (PWMFY), and 23 herds in the upper 25th percentile of this ranking were designated ...
متن کاملReproductive Innovations: Control of Sow Estrus and Breeding
The increasing successful use of artificial insemination is facilitated by a greater knowledge of the biology of the sow during her estrous period. The realization of the importance of establishing an adequate sperm reservoir in the oviduct at an appropriate time relative to ovulation has led to advances in the management of artificial insemination. In particular, knowledge of when a sow is lik...
متن کاملFactors for improving reproductive performance of sows and herd productivity in commercial breeding herds
We review critical factors associated with reproductive performance of female breeding pigs, their lifetime performance and herd productivity in commercial herds. The factors include both sow-level and herd-level factors. High risk sow-level groups for decreasing reproductive performance of female pigs are low or high parity, increased outdoor temperature, decreased lactation feed intake, singl...
