Abstract

Supplementation emerges as a simple strategy to improve animal productivity in systems that adopt deferred grass pasture as the basic diet. This study aimed to evaluate the effect of levels of supplementation of mesquite pod meal on intake, digestibility of nutrients, and body weight (BW) gain of goats in grazing deferred. Thirty-five (35) goat males (24.0 ± 2.9 kg BW) were distributed in a completely randomized design, with five treatments and seven replications. Treatments constituted a supplement control (0.05% BW of protein-mineral salt) and increasing levels at 0.5; 1.0; 1.5, and 2.0% BW of supplementation with mesquite pod meal. Dry matter intake and nutrients of the forage and total diet increased linearly (P<0.0001) as a function of the levels of the supplement. A quadratic effect was observed (P<0.0001) for the digestibility variables, except for ethereal extract and non-fiber carbohydrates, which presented an increasing linear effect (P<0.0001). Supplementation levels increased linearly on the performance variables (P<0.05). It is recommended the concentrate supplementation at 2.0% BW with mesquite pod meal at 30 % in its composition for promoting the reduction of the productive cycle of goats in deferred Urochloa grass pastures.

在半干旱地区的一片推迟放牧的草地(乌洛克洛亚·莫桑比森斯)中添加清真寺豆粉的山羊
在采用延迟草牧场作为基本饮食的系统中,补充营养是提高动物生产力的一种简单策略。本研究旨在评估在推迟放牧的情况下,添加甲硫氨酸豆粕水平对山羊摄入量、营养物质消化率和体重(BW)增加的影响。三十五(35)只山羊雄性(24.0±2.9 kg BW)采用完全随机设计进行分配,共进行五次处理和七次重复。处理构成了补充对照(0.05%BW的蛋白质矿物盐)和在0.5时增加水平;1.0;1.5和2.0%BW。饲料和总日粮的干物质摄入量和营养素随补充剂水平线性增加(P<0.0001)。观察到除乙醚提取物和非纤维碳水化合物外的消化率变量的二次效应(P<0.0001),其呈现出增加的线性效应(P<0.0001)。补充水平对性能变量呈线性增加(P<0.05)。建议在2.0%BW时补充浓缩物,并在其成分中添加30%的梅斯基特荚粉,以促进推迟的乌罗奇洛阿草牧场山羊生产周期的缩短。

期刊介绍: The MEXICAN MAGAZINE OF SCIENCES PECUARIAS is an organ of scientific and technical diffusion of the livestock sector. Its periodicity is quarterly and arbitrated by pairs in the double-blind mode. Its objective is to make known the results of the research carried out by any scientific institution, in Mexico and in any part of the world, related to the livestock sciences, particularly those that refer to the different disciplines of Veterinary Medicine and Animal Science. The Journal is bilingual, publishes the complete articles in Spanish or English and is included in various indexing services and international dissemination platforms, such as the Index of Mexican Journals of Scientific and Technological Research of the National Council of Science and Technology (CONACYT); In the EBSCO Host database; In the Network of Scientific Journals of Latin America and the Caribbean, Spain and Portugal (RedALyC); In the Ibero-American Network of Scientific Journals of Free Access Veterinary Medicine. Indexed in the ISI Journal Citation Report Science Edition; And Elsevier''s SCOPUS and EMBASE indices.
