摘要

本试验采用部分双列杂交对3个品种的兔断奶前后性状进行了一般配合力(GCA)和特定配合力(SCA)测定。当地兔(L),佛兰德巨人(F),和雷克斯(R)。体重在0 (BW0) 30 (BW30), 42 (BW42)和63年(BW63)天的年龄、平均每日收益从0到30 d的年龄(ADG0-30),从30 42 d的年龄(ADG30-42), 42 - 63 d (adg42 - 63)岁,从30到63 d的年龄(adg30 - 63),垃圾大小在出生(LS0)和断奶(LS42)和死亡率在断奶(MR42)研究了在十字路口会,FF, RR,低频,LR,和FR。当地品种最高GCA BW0, BW30, BW42,断奶前平均日增重(adg42 ~ 63)、产仔数(LS0、LS42)和死亡率(MR42)的GCA均高于雷克斯，与佛兰芒巨兽相似。杂交LF和LR对BW30、BW42、BW63、ADG0-30、ADG42-63和ADG30-63的SCA均高于FR。综上所述，基于GCA和SCA，印尼地方品种与佛兰德巨人和雷克斯品种杂交具有较高的遗传潜力。

Partial diallel cross for assessing genetic merit of local rabbit breed

This study was carried out to estimate general combining ability (GCA) and specific combining ability (SCA) of pre-and post-weaning traits from a partial diallel cross in three rabbit breeds: Local rabbit (L), Flemish Giant (F), and Rex (R). Body weight at 0 (BW0), 30 (BW30), 42 (BW42), and 63 (BW63) days of age, average daily gains from 0 to 30 d of age (ADG0-30), from 30 to 42 d of age (ADG30-42), from 42 to 63 d of age (ADG42-63), and from 30 to 63 d of age (ADG30-63), litter size at birth (LS0) and at weaning (LS42), and mortality at weaning (MR42) were studied in crossing LL, FF, RR, LF, LR, and FR. Local breed had the highest GCA for BW0, BW30, BW42, and average daily gain before weaning (ADG0-30, and ADG30-42) compared to Flemish Giant and Rex, while GCA of Local breed for average daily gain after weaning (ADG42-63), litter size (LS0, and LS42), and mortality (MR42) was higher than for Rex and similar to that of Flemish Giant. Crossing LF and LR showed higher SCA for BW30, BW42, BW63, ADG0-30, ADG42-63 and ADG30-63 than FR. In conclusion, based on GCA and SCA, the Indonesian Local breed has a high genetic potential in the crossing with Flemish Giant and Rex breeds.

期刊介绍： World Rabbit Science is the official journal of the World Rabbit Science Association (WRSA). One of the main objectives of the WRSA is to encourage communication and collaboration among individuals and organisations associated with rabbit production and rabbit science in general. Subject areas include breeding, genetics, production, management, environment, health, nutrition, physiology, reproduction, behaviour, welfare, immunology, molecular biology, metabolism, processing and products. World Rabbit Science is the only international peer-reviewed journal included in the ISI Thomson list dedicated to publish original research in the field of rabbit science. Papers or reviews of the literature submitted to World Rabbit Science must not have been published previously in an international refereed scientific journal. Previous presentations at a scientific meeting, field day reports or similar documents can be published in World Rabbit Science, but they will be also subjected to the peer-review process. World Rabbit Science will publish papers of international relevance including original research articles, descriptions of novel techniques, contemporaryreviews and meta-analyses. Short communications will only accepted in special cases where, in the Editor''s judgement, the contents are exceptionally exciting, novel or timely. Proceedings of rabbit scientific meetings and conference reports will be considered for special issues. World Rabbit Science is published in English four times a year in a single volume. Authors may publish in World Rabbit Science regardless of the membership in the World Rabbit Science Association, even if joining the WRSA is encouraged. Views expressed in papers published in World Rabbit Science represent the opinion of the author(s) and do not necessarily reflect the official policy of the WRSA or the Editor-in-Chief.
