宗地花猪产区保种选育基础群繁殖性能测定

Determination of the Reproductive Performance of the Conservation and Breeding Base Population of Zongdihua Pig

以产区的农户为单位组建宗地花猪保种选育基础群,并进行繁殖性能研究测定。结果表明:宗地花猪母猪性成熟早、受胎率高、母性好、泌乳力强,初情期为97.5±8.6日龄,发情周期为19±1.5天,初配年龄为139.5±10.3日龄,妊娠期为113.5±1.2天。初产母猪窝产仔数5.42±1.71头,初生窝重3.19±1.09kg,断奶头数5.05±1.15头,断奶头重8.11±0.57kg。经产母猪窝产仔数8.71±1.99头,初生窝重6.29±1.98kg,断奶头数7.51±2.34头,断奶头重10.02±0.96kg。公猪性成熟早,性欲旺盛,55±8.5日龄就有爬跨行为,性成熟期90日龄左右,适配年龄150日龄左右。研究测定结果为宗地花猪基础群的选种选育提供了参数。

In the Zongdihua Pigs producing areas, We set up a Zongdihua Pigs Foundation Group of Breeding and Selection, and researched the reproductive performance. The results show that Zongdihua Pigs sows have more sexual maturation, higher conception rate, earlier maternity, and lactation stronger than others, puberty for 97.5 ±8.6 days, pregnancy 113.5±1.2 days, the number of brood primipareus sows 5.42 ± 1.71 pigs, new - bombrood weight 3.19 ± 1.09 kg, the number of weaning 5.05 ± 1.15 pigs, the number of weaning 8.11 ±0.57 kg; the broodnumber of producing sows 8.71 ± 1.99 pigs, new - born brood weight 6.29 ± 1.98 kg, the number of Weaning 7.51 ± 2.34 pigs, the number of weaning 10.02 ± 0.96 kg. These Boars possess early sexual maturation, sexual vitality, and mounting behavior 55 ± 8.5 days, sexual maturity around 90 days, adapters around the age of 150 days. The results of research will offer reference data for breeding and selection foundation group of Zongdihua Pigs.
