Frequency Weaning - Fertilization Interval in Large White Sows
Keywords:
frequency, sows, weaning-fertilization intervalAbstract
The time from weaning to fertilization is a non productive interval in sows fertility. The present paper has studied the number of weaned piglets and farrowing rang as factors of influence in sows fertility, based on 1230 deliveries in Large White sows. The purpose of the research is to find end recommend measures for reducing this non productive interval. The analysis of this study showed the following results: 55.04% in first farrowing sows and 80.65% in the older ones were fertilized within 12 days after weaning farrows. The average time of the interval from weaning piglets to fertilization was 9 days in older sows and 16 days in gilts.
