Abstract

The objective of the study was to highlight the morphometric characteristics and conformation of the Nélore bovine breed in order to control their breeding. The animals were all about three (3) years old. The measurements and conformation involved 89 heifers and 28 breeding bulls from a herd of 2,587 heads. The body measurements concerned were evaluated by the traditional method of the measuring board and measuring tape. The average live weight of males was 418.97 kg ± 25.84 kg and that of females 333.67 ± 33.12 kg. The Common coat colour is uniform white, with dark extremities in the males. The conformation indicates good beefing abilities and the males are large. The height at the withers was 1.54 ± 0.01 m and 1.48 ± 0.03 m for males and females respectively. The scapuloischial length of 1.89 ± 0.03 m and 1.81 ± 0.02 for males and females respectively and thoracic perimeter of 1.82 ± 0.03 m and 1.72 ± 0.03 m respectively for males and females. The correlation of body weight was more marked with the height at the withers (r = 0.926) than with the thoracic perimeter (r = 0.81) and the scapuloischial length (r = 0.730). It is therefore important that the breeders study the measurements and conformation in order to appreciate the future breeding abilities of the animals on a farm.

刚果共和国Cuvette地区kira牧场的nelore牛(Bos indicus)的形态

本研究的目的是为了突出nsamolo牛品种的形态特征和构象，以便控制其繁殖。这些动物都大约三岁。测量和构象涉及89头小母牛和28头公牛，这些公牛来自一群2587头牛。采用传统的测量板和卷尺测量方法进行测量。雄性平均活重为418.97 kg±25.84 kg，雌性平均活重为333.67±33.12 kg。常见的毛色是均匀的白色，雄性的末端是深色的。这一构造表明它们具有良好的觅食能力，雄性体型较大。雌马和雄马的肩高分别为1.54±0.01 m和1.48±0.03 m。男女肩胛骨长度分别为1.89±0.03 m和1.81±0.02 m，胸围分别为1.82±0.03 m和1.72±0.03 m。体重与马肩隆高度(r = 0.926)的相关性高于胸围(r = 0.81)和肩胛骨长度(r = 0.730)。因此，育种人员研究测量和构象是很重要的，以便评估农场动物未来的育种能力。Dimi et al.， 2020动物与植物科学杂志(j .
