【摘要】 对广西区畜牧研究所陆川猪保种场2004~2006年间纯种陆川母猪产仔资料进行统计分析,发现陆川猪性成熟较早,窝产仔数和活仔数在第5-8胎时达到高峰;同时,研究不同胎次与产活仔数间的内在联系,模拟出陆川猪产仔规律的数学模型y=7.3813+1.5003x-0.1114x2及校正系数,为陆川猪的选育和良种推广提供理论指导。更多还原

【Abstract】 In 2004-2006,the reproductive performance information of 914 litter purebred Luchuan sows in conservation farm of Guangxi Animal Husbandry Research Institute was analyzed.The results showed that the sexual maturity of Luchuan pigs was very early,and the peak of litter size and survival rate of piglets was from fifth to eighth fetus.Moreover,the mathematical model for littering regular of Luchuan sows was simulated as Y=7.3813+1.5003x-0.1114x2,and the correction coefficient was obtained.The research results would provide theoretical guidance on breeding and extension of Luchuan pigs.更多还原
