Carcass characteristics of lambs fed diets containing silage of different genotypes of sorghum

Abstract

-Thirty-five feedlot lambs (without defined breed, aged between 5 and 7 months, with average live weight of 17.7±3.7 kg) were used in a completely randomized design to evaluate the effect of diets containing different genotypes of sorghum on morphometric measurements and qualitative characteristics of carcass and yields of primal cuts. The animals stayed in individual indoor pens for 42 days and slaughtered at an average weight of 26.24 kg. No significant differences were observed on morphometric measurements, hot (11.67 kg) and cold (11.39 kg) carcass weight, hot (44.46%) and cold (43.37%) carcass yields, biological yield and on cooling losses. There was also no significant effect of silages of different genotypes of sorghum on the weights and yields of retail cuts (neck, shoulder, rib, loin and leg) and on the subjective evaluation of carcasses. It is possible to finish sheep without defined breed feeding them diets based on silages of sorghum, resulting in carcasses with high yield and good conformation.

Commercial cuts and chemical and sensory attributes of meat from crossbred Boer goats fed sunflower cake‐based diets

“…Thus, consumers prefer healthier meat with better nutritional and sensory qualities and, in many cases, better functional properties (Suassuna et al . ).…”

“…Concern about the eating habits of the population has resulted in a demand for healthier food and higher production standards for food products. Thus, consumers prefer healthier meat with better nutritional and sensory qualities and, in many cases, better functional properties (Suassuna et al 2014).…”

Análise de crescimento da gliricídia submetida a diferentes manejos de corte

“…O cultivo de forrageiras em sequeiro é susceptível as variações climáticas, principalmente os localizados em região de clima tropical. É importante se analisar estratégias para esse ambiente (Suassuna et al, 2014). Neste contexto, Pilau et al (2005) relataram que a disponibilidade e a qualidade da forragem são influenciadas pela espécie forrageira, propriedades do solo, condições climáticas, idade fisiológica e pelo manejo a que está submetida.…”

Exigência de FDN fisicamente efetiva de forragem (FDN>sub<>small<fef>/small<>/sub<) para cordeiros em terminação

“…O efeito negativo da elevação no teor de fibra da dieta sobre o rendimento de carcaça pode ser visto comparando experimentos que forneceram dietas ricas em concentrado (≥90% da MS) e observaram rendimento médio de carcaça de 49% (Ferreira et al, 2014(Ferreira et al, , 2011a com experimentos que forneceram dietas com maiores teores de volumoso e observaram rendimento de carcaça médio de 44,5% (Keles et al, 2018;Manarelli et al, 2019;Mendes et al, 2008;Suassuna et al, 2014). Entretanto, os resultados do presente experimento claramente mostraram que o limite máximo de inclusão de FDNfef na dieta para que não houvesse maior comprometimento no rendimento de carcaça foi 5,2% da MS.…”
