육용종계의 교배조합이 실용계의 사양과 경제성에 미치는 영향
A Study on Effects of Breeding Combination for Feeding and Economic Analysis in Broiler Stock
초록
브로일러 산육능력 개량을 위한 우량 교배조합을 선발할 목적으로 결합능력추정과 부계통 모계통의 선발 지침을 분석하기 위하여 본 시험은 1978년 9월28일부터 1979년 1월 5일까지 약 14주간 부계통 4계종과 모계통 3계종으로부터 작출된 브로일러 1,440수를 가지고 한협종계장에서 실시되었으며 그 결과를 요약하면 다음과 같다. 1. 브러일러의 생존율에서 잡종강세의 효과는 나타나지 않았고 생존율의 개량을 위해서는 Hubbard를 부계통으로 선발하는 것이 바람직 한 것으로 사료되었다. 2. 8주령시 체중에서 부, 모계통 모두 Ross의 이용이 바람직스럽고 특수결합능력을 이용한 우량교배조합으로는 Hubbard
In order to identify the best superior cross combination of breeder stocks for broiler production, combining ability test and analyses of phenotypic performances for parent stocks were examined on records of 1,440 broiler chicken which were produced from 4 parental strains and 3 maternal strains at Hanhyup Poultry Breeding Farm from September 28, 1978 to January 5, 1979. The results obtained were as follows; 1. There was not found heterosis effect in viability but it seems to be desirable to select Hubbard strain in paternal line to improve viability. 2. As the paternal and maternal lines, selection of Ross strain showed the best paternal and maternal performance and the best general combining ability in body weight at 8 weeks of age is expected to be able to improve body weight of it s crossbred And the most superior cross combinations based on the specific combining ability and performance of rack crossbred were identified as Hubbard x Ross ana Ross x Hypeco crossbreds. 3. The best paternal and maternal lines on the smallest feed consumption for 8 weeks were Hubbard and Ross strains, and Hypeco strain, respectively. Especially Hubbard x Hypeco cross combination was proved as the smallest feed consumption compared with other cross combinations. 4. In feed requirement per Kg body weight increase, Hubbard strain for paternal line, Hypeco strain for naternal line, and cross combinations of Hubbard x Hypeco, Hubbard x Ross and Ross x Hypeco were certified as the most superiors. 5. Also superior cross combinations of Hubbard x Hypeco and Hubbard x Ross earned the most profit per bird through economic analysis. According to results as shown above, this experiment seems to be able to reach a such conclusion that production of superior cross combinations Hubbard x Ross, Hubbard x Hypeco and Ross x Hypeco through selection of Ross and Hubbard strains to paternal line and Hypeco and Ross strains for maternal line may become to considerable improvement for important economic characters of broiler; viability, body weight, feed consumption and feed requirement.
