【摘要】：關(guān)中黑豬作為陜西關(guān)中地區(qū)優(yōu)良的培育品種,具有抗病力強(qiáng)、耐粗飼和肉品質(zhì)好等優(yōu)良特性。但培育成功之后,一直沒有得到較好的保護(hù)和利用,從而導(dǎo)致這一優(yōu)秀培育品種的種質(zhì)性狀逐漸退化。相比于關(guān)中黑豬,二花臉豬優(yōu)秀的繁殖性能一直受到育種工作者的青睞,具有種群數(shù)量大、種質(zhì)特性好等優(yōu)點(diǎn),并且得到了很好的保護(hù)。為了利用關(guān)中黑豬和二花臉豬的優(yōu)良遺傳基礎(chǔ)來培育出更加優(yōu)良的品種(系),本試驗(yàn)以關(guān)中黑豬作為母本、二花臉豬作為父本的二元雜交豬作為研究對象,測定其肥育性能與肉質(zhì)性狀并與關(guān)中黑豬比較分析。結(jié)果表明:1、生長發(fā)育性能:花關(guān)二元雜交豬四月齡體重、體長、體高、胸圍和管圍較關(guān)中黑豬同期分別增長了22.74%、6.27%、1.67%、5.20%、7.09%;花關(guān)二元雜交豬六月齡體重、體長、體高、胸圍和管圍較關(guān)中黑豬同期分別高6.12%、3.28%、9.30%、7.74%、10.53%。2、育肥性能:花關(guān)二元雜交豬育肥效果較為顯著,日增重比關(guān)中黑豬提高15.45%;料重比比關(guān)中黑豬低16.57%。3、胴體品質(zhì):花關(guān)二元雜交豬屠宰率、背膘厚、脂肪率和板油比例均顯著低于關(guān)中黑豬(P0.05)。4、肉質(zhì)性能:花關(guān)二元雜交豬的滴水損失、失水率、總不飽和脂肪酸、必需氨基酸含量和鮮味氨基酸均顯著高于關(guān)中黑豬(P0.05);花關(guān)二元雜交豬熟肉率、剪切力、大理石紋、飽和脂肪酸含量均顯著低于關(guān)中黑豬(P0.05)。綜上所述,花關(guān)二元雜交豬的生長和肥育性能明顯優(yōu)于關(guān)中黑豬,而肉質(zhì)性能較關(guān)中黑豬差。
[Abstract]:Guanzhong Black Pig, as an excellent breed in Guanzhong area of Shaanxi Province, has excellent characteristics such as strong disease resistance, good forage tolerance and good meat quality, but it has not been well protected and utilized since it was successfully cultivated. Compared with Guanzhong black pig, Erhualian pig's excellent reproductive performance has been favored by breeders, with the advantages of large population and good germplasm characteristics. In order to use the excellent genetic basis of Guanzhong Black Pig and Erhualian Pig to develop better breeds, this experiment uses Guanzhong Black Pig as the female parent. The fattening performance and meat quality of Erhualian pig as male parent were measured and compared with that of Guanzhong black pig. The results showed that the growth and development performance of Erhualian crossbred pig was four months old, body length and body height. The body weight, body length and body height of Huaguan binary crossbred pigs were 6.12 ~ 3.285.309.307.7410.535.53.2. the fattening performance of Huaguan crossbred pigs was more significant than that of Guanzhong black pigs in the same period, and the weight, body length and body height of Huaguan binary crossbred pigs were higher than that of Guanzhong black pigs respectively in the same period, and the fattening performance of Huaguan binary crossbred pigs was more significant than that of Guanzhong Black Pigs, and the weight, body length and body height of Huaguan binary crossbred pigs were higher than that of Guanzhong Black Pig respectively in the same period. Daily gain was 15.45% higher than that of Guanzhong Black Pig, feed weight was 16.57% lower than Guanzhong Black Pig, carcass quality: slaughter rate, backfat thickness, fat rate and fat ratio of Huaguan binary crossbred were significantly lower than those of Guanzhong Black Pig P0.050.4.Meat quality performance: drip loss of Huaguan binary crossbred pigs. Water loss rate, total unsaturated fatty acid, essential amino acid content and taste amino acid content were significantly higher than those of Guanzhong Black Pig (P0.05), and the content of cooked meat, shear force, marbling and saturated fatty acid in Huaguan binary crossbred pigs were significantly lower than those in Guanzhong Black Pig P0.050.In conclusion, The growth and fattening performance of Huaguan binary crossbred pig was obviously better than that of Guanzhong black pig, but the meat quality performance was worse than that of Guanzhong black pig.
