Abstract

The effect of breed on growth, characteristics, and carcass classification was investigated using 11 Charollais x Pelibuey (ChP) lambs, 10 Dorper x Pelibuey (DP) lambs, and 18 Pelibuey (P) lambs in an intensive production system in a warm-humid climate. A significant effect of genotype ( <0.05) was observed on birth weight (BW), weaning weight (WW), and daily weight gain (DWG), all of which were higher in the ChP genotype. ChP and DP lambs reached commercial weight 35 and 23 d earlier, respectively than P lambs. Genotype has a marked influence on the carcass characteristics, affect conformation and classification of carcass. The probability of obtaining a carcass with good conformation and MEX 1 classification (good: MEX 1) is 72 % higher for the ChP genotype than for the P genotype. The loin and leg yields of the ChP genotype were higher than those of the other genotypes. The pH, temperature, and instrumental color of the carcass, meat, and subcutaneous fat were affected by genotype. ChP lambs showed better growth, characteristics, and carcass classification than lambs of the DP and P genotypes.

在温暖潮湿气候下集约化生产系统下饲养的纯Pelibuey羔羊和杂交羔羊尸体的生产性能和分类

在一个温湿气候的集约化生产系统中，研究了品种对11只夏羊×佩利布羊(ChP)、10只杜珀羊×佩利布羊(DP)和18只佩利布羊(P)生长、性状和胴体分类的影响。基因型对仔猪出生体重(BW)、断奶体重(WW)和日增重(DWG)均有显著影响(<0.05)，且ChP基因型高于ChP基因型。ChP组和DP组分别比P组提前35天和23 d达到商品体重。基因型对胴体性状有显著影响，影响胴体的构象和分类。ChP基因型获得良好构象和MEX 1分类(良好:MEX 1)的胴体的概率比P基因型高72%。ChP基因型的腰、腿产量均高于其他基因型。pH、温度和胴体、肉和皮下脂肪的仪器颜色受基因型的影响。ChP羔羊的生长、性状和胴体分类优于DP和P基因型羔羊。

期刊介绍： The MEXICAN MAGAZINE OF SCIENCES PECUARIAS is an organ of scientific and technical diffusion of the livestock sector. Its periodicity is quarterly and arbitrated by pairs in the double-blind mode. Its objective is to make known the results of the research carried out by any scientific institution, in Mexico and in any part of the world, related to the livestock sciences, particularly those that refer to the different disciplines of Veterinary Medicine and Animal Science. The Journal is bilingual, publishes the complete articles in Spanish or English and is included in various indexing services and international dissemination platforms, such as the Index of Mexican Journals of Scientific and Technological Research of the National Council of Science and Technology (CONACYT); In the EBSCO Host database; In the Network of Scientific Journals of Latin America and the Caribbean, Spain and Portugal (RedALyC); In the Ibero-American Network of Scientific Journals of Free Access Veterinary Medicine. Indexed in the ISI Journal Citation Report Science Edition; And Elsevier''s SCOPUS and EMBASE indices.
