【摘要】：【目的】研究圩猪与三元杂交猪在相同日粮和饲养期内生长性能及肉品质的差异。【方法】选择体质量为(60±2.42)kg的圩猪和三元杂交猪(杜×大×长)各12头,每个品种随机分为2组,每组6个重复,公母各半。按三元杂交猪的营养需要配制试验饲粮,采用种猪自动饲喂系统饲喂35和50d后各屠宰1组,比较其生长性能和肉品质的差异。【结果】饲养50d的圩猪平均日增体质量显著低于三元杂交猪(P0.05),料体质量比显著高于三元杂交猪(P0.05)。相同饲养期内,圩猪肉的大理石纹评分、肌内脂肪、肌苷酸、必需氨基酸以及饱和脂肪酸的含量均显著高于三元杂交猪(P0.05),而其肌肉滴水损失、硬度、肌纤维直径和多不饱和脂肪酸含量则显著低于三元杂交猪(P0.05)。【结论】与三元杂交猪相比,圩猪生长速度缓慢,饲粮转化率低,但具有优良的肉质性状和风味特性。
[Abstract]:[objective] to study the difference of growth performance and meat quality between wewe-pig and three-way crossbred pig in the same diet and feeding period. 12 heads each. Each breed was randomly divided into 2 groups, 6 replicates in each group, half male and half female. The experimental diet was prepared according to the nutritional needs of the three dimensional crossbred pigs, and the breeding pigs were fed with automatic feeding system for 35 days and 50 days later, each group was slaughtered. The difference of growth performance and meat quality was compared. [results] the average daily gain of fair pigs fed for 50 days was significantly lower than that of three-way crossbred pigs (P0.05). The ratio of feed to body weight was significantly higher than that of three-way crossbred pig (P0.05). During the same feeding period, marbling score, intramuscular fat and inosine acid were measured. The contents of essential amino acids and saturated fatty acids were significantly higher than that of P0.05A, but the muscle dripping loss and hardness were also observed. The diameter of muscle fiber and the content of polyunsaturated fatty acids were significantly lower than that of P0.05. [conclusion] compared with the three-way crossbred pigs, the growth rate and the dietary conversion rate of the wee pigs were lower than those of the three-way crossbred pigs. But it has excellent meat quality and flavor characteristics.
