Abstract

: This study was conducted to observe characteristics and preweaning growth traits of calves born from crossbreeding between Wagyu and Belgian Blue (BB) bulls with Brahman Cross (BX) dams. The experiment was conducted to compare two different crosses Belgian Blue (BB) x BX, Wagyu x BX and also with BX pure breed (BX x BX). In the first two crosses, we used Artificial Insemination (AI), while in the third natural mating occurred. The number of calves in the experiment was 18 from the first cross (BB-crossed), 17 from the second cross (Wagyu-crossed), and 15 from the third (BX).BB The calves were raised together with their dams until they reached weaning age in 180 days. The data collected was analyzed by Kruskal-Wallis Test and Mann-Whitney Test for significant differences. The coat colors of BB-crossed calves were predominantly black (77.22%), and all Wagyu-crossed calves were red; whereas BX calves' coat colors vary: 37.5% black, 31.25% red, and 31.25% white. There was no significant difference among groups in body size (except the withers height) and weight at birth. The BB-crossed, Wagyu-crossed and BX calves showed the preweaning growth on body length of 0.15±0.03, 0.17±0.03 and 0.11±0.03 cm/day; withers height of 0.18±0.02, 0.14±0.02 and 0.10±0.02 cm/day; heart girth of 0.32±0.05, 0.24±0.03 and 0.16±0.03 cm/day and daily body weight of 0.74±0.13, 0.62±0.06 and 0.39±0.11 kg/day respectively. The average daily gain of body length on BB-crossed and Wagyu-crossed calves was higher (P<0.05) than that of BX calves. The average withers height, heart girth, and body weight daily gain of BB-crossed calves were higher (P<0.05) than those of Wagyu-crossed calves and Wagyu-crossed calves were higher (P<0.05) than those of BX calves. It is concluded that crossing Brahman Cross dams with Belgian Blue and Wagyu bulls improves body size and weight gain of calves; further, crossbreeding with Belgian Blue bulls gives better improvement than that with Wagyu bulls.

婆罗门杂交坝比利时蓝与和牛杂交特性及断奶前生长

本试验旨在观察婆罗门杂交(BX)和牛与比利时蓝(BB)公牛杂交后犊牛的性状及断奶前生长性状。本试验比较了比利时蓝(BB) × BX、和牛× BX以及与BX纯种(BX × BX)杂交的不同品种。前两次配种采用人工授精，第三次配种采用自然配种。试验犊牛数量:1个杂交(bb杂交)18头，2个杂交(和牛杂交)17头，3个杂交(BX杂交)15头。犊牛与母犊一起饲养，直至180天达到断奶年龄。收集的数据采用Kruskal-Wallis检验和Mann-Whitney检验进行分析，是否存在显著差异。bb杂交犊牛的被毛以黑色为主(77.22%)，和牛杂交犊牛的被毛均为红色;而BX小牛的皮毛颜色各异:37.5%为黑色，31.25%为红色，31.25%为白色。各组间出生时体大小(除肩高外)和体重均无显著差异。bb系、和渝系和BX系犊牛断奶前体长分别为0.15±0.03、0.17±0.03和0.11±0.03 cm/d;残峰高度分别为0.18±0.02、0.14±0.02和0.10±0.02 cm/天;心围分别为0.32±0.05、0.24±0.03和0.16±0.03 cm/d，日体重分别为0.74±0.13、0.62±0.06和0.39±0.11 kg/d。bb杂交和和渝杂交犊牛的平均日增重高于BX犊牛(P<0.05)。bb杂交犊牛的平均肩高、心围和体重日增重均高于和牛杂交犊牛(P<0.05)，和牛杂交犊牛的平均肩高、心围和体重日增重高于BX犊牛(P<0.05)。综上所述，婆罗门十字坝与比利时蓝、和牛杂交可提高犊牛体尺和增重;此外，与比利时蓝牛杂交比与和牛杂交有更好的改良效果。

期刊介绍： American Journal of Animal and Veterinary Sciences, a quarterly, peer reviewed publication and is dedicated for publication of research articles in the field of biology of animals and with the scientific understanding of how animals work: from the physiology and biochemistry of tissues and major organ systems down to the structure and function of bio molecules and cells; particular emphasis would given to the studies of growth, reproduction, nutrition and lactation of farm and companion animals and how these processes may be optimized to improve animal re- productivity, health and welfare. Articles in support areas, such as genetics, soils, agricultural economics and marketing, legal aspects and the environment also are encouraged. AJAVS is an important source of researcher to study articles on protection of animal production practices, herd health and monitoring the spread of disease and prevention in both domestic and wild animals.
