沙子岭猪肥育性能与肉质特性研究

Research on Sha Zi-Ling Pig's Specific Property of Fatten Capacity Meat Quality

本试验选择16头沙子岭纯种仔猪,随机分成二组,分别饲喂不同能量、蛋白水平的日粮,探讨营养水平对沙子岭猪肥育性能与胴体品质性状的影响。结果表明:低水平和高水平组日增重分别为411.38g、445.75g,差异不显著(P>0.05);饲料报酬分别为4.82∶1、4.48∶1;每公斤增重饲料成本分别为6.60元、6.54元;胴体瘦肉率分别为44.59%、40.82%,差异不显著(P>0.05)。与国内地方猪种比较,沙子岭猪具有生长速度较快、屠宰率较高、眼肌面积较大、背膘较薄、瘦肉率较高的特点。

On experiment, we choose 16 pure Sha ZiLing piglets, divided in two groups at random, raised with forage in different level of energy and protein, to study the influence of different nutrition level on fatten capacity and meat quality of Sha ZiLing pig. The result shows. Low Level and high level groups daily adding weight are 411.38 g, 445.75 g, no obvious difference (P>0.05); Rewards of forage are 4.82∶1, 4.48∶1; Cost of each kg are 6.60, 6.54 Yuan; Rates of lean meat are 44.59%, 40.82%, no obvious difference (P>0.05). Comparing with chinese other local breeds, Sha ZiLing pig has the characteristics of rapid growing, high dressing percentage, large eye muscle, thin back fat, high lean meat percentage etc.\;
