摘要/Abstract

摘要：

目的该试验旨在测定杜洛克与赣南藏香猪杂交后代的生长性能、屠宰性能、肉质性状等指标，分析杂交后代的生产性能变化。方法通过选取3头杜洛克公猪与3头赣南藏香猪母猪进行杂交，其后代分组进行分栏饲养，至体成熟后每栏选取2头屠宰，并测定各项生产性能指标。结果结果显示，与赣南藏香猪相比，杜赣杂交后代体重明显增大，屠宰率和瘦肉率得到显著提升（P＜0.05）；背最长肌中粗蛋白质含量无显著变化（P＞0.05），但肉色评分显著降低（P＜0.05），且肌纤维直径显著变粗（P＜0.05），肌纤维密度显著下降（P＜0.05）；背最长肌中总氨基酸含量无明显变化（P＞0.05），但呈味氨基酸含量显著下降（P＜0.05）。结论可见，选取杜洛克作为父本进行杂交后，杜赣杂交后代生长性能得到有效提升，但猪肉品质呈现明显下降趋势。

Abstract:

Objective This study aimed to evaluate growth performance, slaughter characteristics, and meat quality traits in hybrid offspring from Duroc and Gannan Tibetan pig crossbreeding, while analyzing changes in production efficiency. Method Three Duroc boars were crossbred with three Gannan Tibetan sows, with their offspring divided into groups for rearing. Upon reaching physical maturity, two pigs from each group were randomly selected and slaughtered to determine the various production parameters. Result The results showed that compared with Gannan Tibetan pigs, the body weight of Dugan hybrid offspring was significantly increased (P < 0.05), the slaughter rate and lean meat rate were significantly increased (P < 0.05). There was no significant change in crude protein content in longissimus dorsi muscle (P > 0.05), but the meat color score was significantly reduced(P < 0.05), and the muscle fiber diameter was significantly thicker (P < 0.05). The muscle fiber density decreased significantly (P < 0.05), but the flavor amino acid content decreased significantly (P < 0.05). Conclusion The findings indicate that using Duroc as the sire effectively enhances growth performance in hybrids, yet leads to a noticeable decline in pork quality.
