摘要

本文介绍了利用Eurosomy指数对不同杂交分化的大型白猪的育肥性和肉质进行研究的结果,并分析了数量性状的离散系数及其在工业综合体条件下使用的经济效益。根据个体发育、育肥和肉品质的指标进行动物评价,考虑以下特点:对照育肥最后一天仔猪的活重,kg;体长,厘米;肩胛骨后胸围,厘米;对照育肥期平均日增重g;日龄达到活重100公斤,日龄;冷却胴体长度,cm;熏肉在6-7胸椎水平的厚度,mm。Eurosomia指数的计算方法采用S. V. Akimov(2005)的方法,并按照普遍接受的方法进行生物识别处理,对研究结果进行经济效益分析。结果表明,对照群体大白猪的体长、活重达到100 kg的年龄、猪油厚度达到6 ~ 7节胸椎水平、冷冻胴体长度等指标均为1级和精英级。成立第一个实验组的幼猪可靠第二实验组优于同行的活体重的最后一天控制肥胖,身体长度、胸腰围在肩胛骨,日均生活增加体重肥胖控制期间,年龄达到活体重100公斤,长度的冷冻的尸体,培根的长度一半的冷冻尸体以年均2.77%的一半。试验组仔猪个体发育、肥育和肉品质的离散系数在0.427 ~ 0.829点之间。Eurosomia指数、发育指标、育肥和肉质之间存在可靠的联系(87.50%),证明在符合最佳饲养和维护水平和兽医安全的条件下,在选择和育种工作中使用这一综合价值是有效的。第一试验组仔猪的额外产量增幅最大,为+2.35%,增加值为+162.47格里夫纳(4.11美元)。

SIGNS OF FEEDING AND MEAT QUALITIES OF YOUNG PIGS OF DIVERSE INTERBREED DIFFERENTIATION ACCORDING TO THE EUROSOMY INDEX AND THEIR LEVEL OF DISCRETION
The article presents the results of the research on the fattening and meat qualities of young pigs of the large white breed of diverse interbreed differentiation due to the Eurosomy index and the analysis of the coefficients of discreteness of quantitative traits and the economic efficiency of their use in the conditions of the industrial complex. Evaluation of animals according to indicators of individual development, fattening, and meat qualities were carried out taking into account the following characteristics: live weight of young pigs on the last day of control fattening, kg; body length, cm; chest circumference behind the shoulder blades, cm; average daily gain of live weight during the period of control fattening, g; the age of reaching 100 kg live weight, days; length of the cooled carcass, cm; thickness of bacon at the level of 6-7 thoracic vertebrae, mm. The Eurosomia index was calculated due to the methodology of S. V. Akimov (2005), the biometric processing, and the analysis of the economic efficiency of the research results were carried out according to generally accepted methods. It was founded that the young pigs of the large white breed of the controlled population correspond to the 1st class and the elite class in terms of body length, age of reaching a live weight of 100 kg, lard thickness at the level of 6-7 thoracic vertebrae and length of the chilled carcass. It was established that the young pigs of the first experimental group reliably outperformed peers of the second experimental group in terms of live weight on the last day of control fattening, body length, chest girth behind the shoulder blades, average daily increase in live weight during the fattening control period, age reaching a live weight of 100 kg, the length of the chilled carcass, the length of the bacon half of the chilled half carcass by an average of 2.77%. The coefficient of discreteness of signs of individual development, fattening, and meat qualities in young pigs of the experimental groups ranges from 0.427 to 0.829 points. The presence of reliable connections (87.50%) between the Eurosomia index, development indicators, fattening, and meat qualities testify to the effectiveness of using this integrated value in selection and breeding work under conditions of compliance with the optimal level of feeding and maintenance and veterinary safety. The maximum increase in additional production was obtained from young pigs of the 1st experimental group - +2.35%, and its value are +162.47 hryvnias or 4.11 US dollars.
