Intake, performance, carcass traits and meat quality of goats grazing in the Caatinga rangeland

Abstract

Spineless cactus provided higher supplement intake for grazing goats. Supplements based on spineless cactus provided greater non-fibrous carbohydrates intake. The highest CP intake occurred in goats supplemented with mororó hay associated with spineless cactus. Food supplementation did not influence goat meat quality.

Native legumes and spineless cactus in supplementation of goats grazing in Caatinga rangeland: intake, performance, carcass characteristics, and meat quality

“…The average values of the post mortem pH at 0 and 24 hours were 6.85 and 5.81, respectively. Final pH values for the goat species grazed in the Caatinga were found by Silva et al (2015), and Silva et al (2020). While the mean values obtained for the color of meat were 38.38 for L* (lightness), 11.75 for a* (redness), and 7.21 for b* (yellowness) (Table 6).…”

“…The dry matter (DM), and organic matter (OM) intakes were higher (p <0.05) for animals supplemented with Leucena hay associated or not with spineless cactus, with increases of 26.50 and 28.48% in the intake of DM and OM in the animals' diet, respectively (Table 2). In previous studies (Souza et al, 2015;Silva et al, 2016;Silva et al, 2020) show that food supplementation maximizes the intake of DM of goats raised on pasture in the Caatinga. Although the supplements increase the intake of DM and OM, the Sabiá hay caused low acceptability by the animals, even associated with the spineless cactus.…”

“…The supplementation strategies to meet the nutritional requirements of goats are extremely important to maintain the weight gain in times of forage scarcity reducing the age of slaughtering. The feed supplementation improves carcass characteristics and meat quality of goats grazing in the Caatinga (Souza et al, 2015;Silva, Guim, Santos, Maciel, & Soares, 2015;Silva et al, 2020). Thus, the aim was to evaluate the effect of supplementation with Leucena hay and Sabiá hay in association or not with spineless cactus on intake, performance, quantitative carcass characteristics, tissue composition, and meat quality of goat grazing in the Caatinga rangeland.…”

Carcass traits of goats finished with different levels of concentrate supplementation and kept on caatinga enriched with Urochloa trichopus

“…Soares et al (30) evaluated the performance of sheep and goats finished on caatinga pasture enriched with buffel grass and supplemented with two types of supplementation (energy and protein-energy), and reported that the performance of these animals was favored by the supply of protein-energy supplementation, which showed higher total weight gain and higher hot and cold carcass weights and empty body weight, indicating the role of protein in the concentrate, meeting the protein deficiency of the pasture. In the study by Silva et al (31) evaluating the carcass traits of non-descript breed goats, raised on caatinga pasture and supplemented with two types of hay: jitirana (Merremia aegyptia) or mororó (Bauhinia cheilanta), combined or not with cactus pear (Nopalea cochenillifera Salm Dick), and a treatment without supplementation (control). Feed supplementation with jitirana and mororó hays, and cactus pear did not improve performance and carcass traits of goats raised on caatinga pasture.…”

Características de carcaça de caprinos terminados com diferentes níveis de suplementação concentrada e mantidos em caatinga enriquecida com Urochloa trichopus

“…Equação de regressão R² CV Parâmetros 0 0,5 Soares et al (30) , ao avaliarem o desempenho de ovinos e caprinos terminados em caatinga enriquecida com capim buffel e suplementados com dois tipos de suplementação (energético e protéico-energético), observaram que o desempenho destes animais foi favorecido pelo fornecimento de suplementação protéicoenergética, os quais apresentaram maior ganho de peso total e maiores pesos de carcaça quente, fria e peso de corpo vazio, indicando o papel da proteína do concentrado, suprindo a deficiência proteica do pasto. Já no trabalho de Silva et al (31) avaliando as características de carcaça de caprinos sem padrão de raça definida, criados em pastejo na caatinga e suplementados com dois tipos de fenos: jitirana (Merremia aegyptia) ou mororó (Bauhinia cheilanta), com ou sem a associação a palma forrageira (Nopalea cochelinifera Salm Dick), e um tratamento sem suplementação (controle). A suplementação alimentar com os fenos de jitirana e mororó, e palma forrageira não proporcionou melhorias no desempenho e nas características de carcaça, de caprinos criados em pastejo em região de caatinga.…”
