Population growth led to an increase in the number of people raising pigs, resulting in increased demand for piglets/pigs for breeding and pork for consumption.
This study was carried out to determine the reproductive performance of pigs raised by the intensive management system in Abuja, Nigeria, with a view to assist farmers in ensuring improved productivity and profitability.
Using an interview-based questionnaire, data from 121 sows and 649 preweaning piglets were collected in 12 herds, from September 2017 to March 2018. Measures of reproductive and production performance assessed in this study were interfarrowing interval (IFI), number of liveborn piglets (NLB), preweaning piglet mortality (PPM), age at weaning (AAW), weaning to service interval (WSI), age at first farrowing (AFF), number of piglets weaned per litter (NPWL), and number of piglets weaned per sow per year (NPWPY).
The results obtained in this study were IFI 6.2±0.84 months, NLB 7.2±1.11, PPM 31%, AAW 40.2±3.12 days, NPWL 5.3±0.73, WSI 39.4±4.59 days, AFF 9.1±0.60 months, and NPWPY 8.1±1.21. The identified causes of PPM were maternal overlay 31.34%, splay leg/hypoglycemia 22.39%, cannibalism 20.40%, starvation 14.93%, and unknown cause 10.94%.
The result showed that the reproductive performance of the sow (especially, NPWPY and PPM) needs to be improved on. There is a need to promote extension and herd health services by veterinarians and livestock personnel to potential and existing farmers in the area. This is more so because organized pig production in the studied area is relatively new and more people are establishing pig farms in the studied area.
人口增长导致养猪人数增加,进而使得用于繁殖的仔猪/猪以及供消费的猪肉的需求上升。
开展本研究以确定尼日利亚阿布贾采用集约化管理系统饲养的猪的繁殖性能,旨在帮助养殖户提高生产力和盈利能力。
2017年9月至2018年3月期间,通过基于访谈的问卷,从12个猪群中收集了121头母猪和649头断奶前仔猪的数据。本研究评估的繁殖和生产性能指标包括胎间距(IFI)、活产仔猪数(NLB)、断奶前仔猪死亡率(PPM)、断奶日龄(AAW)、断奶至配种间隔(WSI)、初产日龄(AFF)、每窝断奶仔猪数(NPWL)以及每头母猪每年断奶仔猪数(NPWPY)。
本研究获得的结果为:IFI 6.2±0.84个月,NLB 7.2±1.11头,PPM 31%,AAW 40.2±3.12天,NPWL 5.3±0.73头,WSI 39.4±4.59天,AFF 9.1±0.60个月,NPWPY 8.1±1.21头。确定的PPM原因包括母猪压死31.34%、八字腿/低血糖22.39%、同类相食20.40%、饥饿14.93%以及原因不明10.94%。
结果表明母猪的繁殖性能(尤其是NPWPY和PPM)有待提高。兽医和畜牧人员有必要向该地区的潜在养殖户和现有养殖户推广推广服务和畜群健康服务。鉴于该研究地区有组织的养猪生产相对较新且越来越多的人在该地区建立猪场,情况更是如此。
