Abstract

For cattle production under grazing conditions, the system characteristic is the multiplicity of elements that interact to make meaningful changes in the eating habits of cattle. This study evaluated diurnal behavior and their productive performance. Grazing cattle were fed with hybrid Brachiaria cv. Mulato II. This study was conducted in a 107 days period between July and October 2010 at Corpoica Turipana Research Center, (Cerete, Colombia). 72 cebu cattle, with an average initial weight of 314 ± 29 kg were used on a 12 hectares field planted with hybrid Brachiaria cv. Mulato II. Two experimental trials were implemented: the first one, using a randomized block design with two replicates using three treatment of 5, 6 and 7 animals/ha. Weight gaining and quality of the fodder were evaluated. The second trial using a randomized block design with three treatments for nine experimental units, monitored daily feeding habits. The quality of the fodder didn’t show any significant difference (P > 0.05), but the time the cattle spent grazing and ruminating while laying down and moving regularly, showed differences (P 0.001). The variables of feeding behavior evaluated, and the weight gaining process were highly influenced by the animal performance.

牛杂交种Mulato II的日摄食行为

对于放牧条件下的牛生产，系统特征是多种因素相互作用，使牛的饮食习惯发生有意义的变化。这项研究评估了他们的日常行为和工作表现。用杂交臂氏菌饲喂放牧牛。Mulato II。本研究于2010年7月至10月在Corpoica Turipana研究中心(哥伦比亚塞雷特)进行，为期107天。试验选用72头平均初始体重为314±29 kg的宿务牛，在12公顷的田中种植杂交臂achiaria cv。Mulato II。试验进行了两项试验:第一项试验采用随机区组设计，设2个重复，分别采用5、6和7只/公顷处理。对饲料增重和品质进行评价。第二项试验采用随机区组设计，分为9个实验单元，采用3种处理，监测日常喂养习惯。饲料质量差异不显著(P < 0.05)，但放牧和反刍时间差异显著(P < 0.001)。饲养行为和增重过程受动物生产性能的影响较大。

期刊介绍： The journal Ciencia y Tecnología Agropecuaria (Science and Agricultural Technology) is a four-monthly scientific publication edited since October 1996 by the Corporación Colombiana de Investigación Agropecuaria - Agrosavia. The journal publishes articles on diverse thematic areas typical of the agricultural sector (multidisciplinary), written in Spanish or English, especially from Latin American and Caribbean researchers. The contributions that apply for the journal must be original and unpublished. The articles are reviewed by national and international peers (peer review). The journal is non-commercial and open access, this means that it doesn’t charge for the reception and/or publication of articles in both, its printed and digital version.
