Abstract

The aim of the study was to evaluate the effect of age on the fattening performance qualities and carcasses slaughter value. The assessment covered 99 crossbred pigs (Danish Landrace × Yorkshire × Duroc). The animals were subdivided into two groups with different slaughter age (159 and 169 days). The assessment covered fattening and post-slaughter characteristics. It has been proven that, at slaughter, younger crossbred pigs showed a higher growth rate than older pigs (P < 0.01). In addition, the former were fattened for a shorter period and consumed less feed across the entire fattening period as well as per 1 kg of gain. Carcasses of pigs older at slaughter were characterised by greater warm carcass weight and height of the loin muscle relative to group I carcasses (P < 0.01). Slaughter value of fatteners from both groups studied was very high, as each of the carcasses under assessment was classified under the most valuable categories S, E, and U.
随屠宰年龄变化的杂交育肥猪生长速率和胴体质量
本试验旨在评价年龄对肥育性能品质和胴体屠宰价值的影响。评价对象为99头杂交猪(丹麦长白猪×约克猪×杜洛克猪)。按屠宰日龄(159日龄和169日龄)再分为两组。评估内容包括肥育和屠宰后特征。已经证明,在屠宰时,年轻的杂交猪比年长的猪表现出更高的生长率(P <0.01)。此外,前者育肥期较短,整个育肥期和每千克增重消耗的饲料较少。屠宰年龄较大的猪胴体的特征是相对于I组胴体具有更大的热胴体重量和腰部肌肉高度(P <0.01)。研究的两组育肥猪的屠宰价值都非常高,因为所评估的每具胴体都被归类为最有价值的S、E和U类。
