摘要

仔猪是养猪业中的一个重要类别,应该与母猪一起被认为是必不可少的生产头。在过去的几十年里,养猪生产中的集约化选择优先考虑经济上重要的性状,从而提高饲料利用率,从更少的母猪中获得更多的仔猪。然而,这样的选择并不能提高仔猪的整体活力和它们在出生后或在产房逗留期间的生存能力。体重在生猪生产中占有重要的地位,尤其是仔猪出生时的体重。根据仔猪的出生体重可以预测许多参数:死亡率和生长率、仔猪的生理状态、对外界影响的敏感性、活力等。本文的目的是测定仔猪从出生到断奶的体重变化(出生时、出生后3小时、出生后24小时和断奶时测量),并研究仔猪在过渡到哺乳期间的出生体重与体重之间的关系。本研究共选用F1代母猪105头仔猪,连续8胎。本文介绍了用描述性统计、方差分析和相关分析得到的结果。仔猪不同生命阶段体重与整体生产参数之间的关系强调了猪舍条件的中心地位,因为仔猪出生时的体重对大龄仔猪的体重有很大影响,特别是在仔猪生命的最初几天。因此,在产仔单位对仔猪的适当照顾对生猪生产至关重要,特别是因为现在仔猪出生时的体重比以前低。

Piglet Body Weight Variation and the Influence of Birth Weight on Piglet Growth During Lactation and Weaning
Summary Piglets are an important category in pig farming which should, alongside sows, be considered essential production heads. Over the past decades, the intensive selection in pig production has given priority to economically important traits resulting in greater feed utilization and obtaining more piglets from fewer sows. However, such selection practices have failed to improve the overall vitality of piglets and their ability to survive immediately after birth or during their stay in the farrowing unit. Body weight is of great importance in pig production, especially the piglet body weight at birth. A number of parameters can be predicted according to the piglet birth weight: mortality and growth rate, the physiological status of the heard, sensitivity to external influences, vitality and etc. The purpose of this paper is to determine the piglet body weight variation from birth to weaning (measured at birth, 3 hours after birth, 24 hours after birth and at weaning) and to examine the relationship between the birth weight of piglets and their body weight during the transition into nursing. A total of 105 piglets were enrolled in this study from the F1 generation sows followed through eight consecutive parities. The paper presents the results obtained using descriptive statistics, as well as variance and correlation analysis. The relationship between the piglet body weight at different stages of their life and overall production parameters was found to emphasize the centrality of housing conditions as the piglet weight at birth exerts a great impact on the body weight of older piglets, especially in the first days of the piglet life. Therefore, the proper care of piglets in farrowing units is of paramount importance to pig production, especially because piglets have lower body weight at birth nowadays than before.
