Abstract

The main objective of this study was to evaluate the production of meat during the dry period in Brachiaria hybrid cv. Mulato II pasture with three stocking rates, irrigated and spring fertilized. The research was conducted for 140 days at the Center for Research Turipana of the Colombian Corporation of Agricultural Research (Corpoica), located at Cerete, Cordoba (Colombia). Were grazed 48 cattle, commercial zebu with average weight of 339 ± 29 kg in an area of 12 hectares. Three treatments (3, 4, 5 animals/ha) were evaluated with two replications in a randomized block design. Production, chemical and botanical composition, in situ degradability of dry matter and the daily weight gain was determined. Economic feasibility was determined by the benefit/cost ratio. The dry matter production was 1.925.16, 1.111.18 and 884.92 kg ha-1 for treatments 3, 4, 5 animal/ha respectively, detected differences (p 0.05). For daily gain analysis found differences (p<0.05), with gains of 1.07, 0.989 and 0.940 kg animal for treatments 3, 4, 5 animal/ha. The treatment 5 animal/ha provided the best indicators economical.

肉类生产灌溉牧场和流失Brachiaria混合的简历。西努山谷的黑白混血二世

本研究的主要目的是评价腕鱼杂交种在干旱期的肉产量。Mulato II型牧场有三种放养率，灌溉和春肥。该研究在位于哥伦比亚科尔多瓦塞雷特的哥伦比亚农业研究公司(Corpoica)的图里帕纳研究中心进行了140天。在12公顷的土地上放牧了48头平均体重339±29公斤的商品瘤牛。采用随机区组设计，对3个处理(3、4、5只动物/公顷)进行2个重复评价。测定了产量、化学和植物成分、干物质原位降解率和日增重。经济可行性是由效益/成本比决定的。3、4、5头/ha处理的干物质产量分别为1.925.16、1.111.18和884.92 kg ha-1，差异均无统计学意义(p 0.05)。日增重分析差异显著(p<0.05)， 3、4、5头/ha处理的日增重分别为1.07、0.989和0.940 kg。5只/公顷的处理具有最佳的经济指标。

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 The contributions that apply for the journal must be original and unpublished.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.
