“…The subjective measurements were possibly attributed to the low acceptability of the diets with ammoniated pearl millet silage, which led to lower live weights at slaughter compared with the other diets. Thus, the values obtained of these measurements in the current study corroborates with Silva et al (2012), who described that the carcass conformation is closely related to the body condition, and as the slaughter weight decreases, conformation values will decrease as well.…”

This study aimed to evaluate the effect of pearl millet silage ammoniated with urea on lamb carcass characteristics and meat quality. Thirty-two noncastrated crossbred lambs at 4-5 months of age, with an average initial body weight of 17.39 ± 2.16 kg, were distributed into four treatments in a randomized block experimental design with eight animals per treatment. Experimental diets were composed of pearl millet silage ammoniated with four levels of urea (0%, 2%, 4% and 6%, on dry matter basis (DM). Carcass conformation and fatness decreased linearly (p < 0.05). Except for the fat content, the proximate composition was not influenced (p < 0.05) by the diets. Meat lightness and yellowness increased linearly (p < 0.05). There was no effect of diets (p > 0.05) on cooking losses or shear force. The levels of oleic and erucic fatty acid levels in the meat decreased linearly (p < 0.05), whereas linoleic and eicosadienoic acids, polyunsaturated fatty acids, PUFA:SFA ratio and ω6 contents increased (p < 0.05). Pearl millet silage ammoniated with urea allows for the production of good-quality lamb meat, with greater concentrations of polyunsaturated fatty acids. However, lambs fed diets with pearl millet ammoniated with up to 6% lead to a reduction of carcass characteristics without significantly affecting loin-eye area possibly associated with low palatability of the additive used. The lower acceptance of the silages with higher levels of urea is due to the ammonia retention in the material is attributed to the ammonization process. Thus, in spite of the benefits on lamb meat quality, it is suggested that the use of this additive in the ammonization of tropical forages be carried out with care, in limits of up to 6%.

“…These results are similar to those found by Silva et al (2012), when evaluating the effect of silk flower hay on the body constituents of confined and slaughtered lambs with 75 days of confinement; as well as to those fund by Vieira et al (2010), who evaluated the non-carcass components of sheep fed with castor-based feed and did not observe differences for the variable viscera, FGIT, EGIT, organs, head and paw; except for the skin, which presented a quadratic effect. These results may be related to the chemical composition of the diets, since according to Moreno et al (2011), the diet can affect the GIT.…”

“…The substitution of buffel grass hay by 'jurema preta' hay in the lambs's diet promoted a quadratic effect on the carcass conformation, estimating a maximum point in 25%, confirming the direct relation with the slaughter weight, corroborating with the results described by Silva et al (2012) in a study with effect of silk flower hay on the carcass and body constituents of lambs.…”

The objective of this study was to evaluate the characteristics of carcass and the non-carcass components of lambs fed with different proportions of buffel grass hay (Cenchrus ciliaris L.) and 'jurema preta' (Mimosa tenuiflora (Willd.) Poir.). The study was developed at the Federal University of Campina Grande, Campus of Patos-PB. Twenty-eight uncastrated lambs with initial body weight of 20 ± 2.49 kg were used. The treatments were the different proportions of 'jurema preta' hays (BJH) and buffel grass hay (BGH) in the bulky portion of the diet: 0% of BJH + 100% of BGH; 33% of BJH + 67% of BGH; 67% of BJH + 33% of BGH; 100% of BJH + 0% of BGH. A quadratic effect was observed for loin eye area, conformation and GR measure ("grade rule"). The thickness measurements of subcutaneous fat and marbling presented negative linear behavior, with the substitution of BGH by BJH. The substitution of BGH in the proportion of 20 to 50% by the BJH of the bulky portion in the lambs' diet allows for a good conformation, loin eye area and non-carcass components.Key words: liver, morphometry, sheep, bulky Carcaça e não constituintes de cordeiros alimentados com capim-buffel e jurema-preta RESUMO Objetivou-se avaliar as características de carcaça e seus não constituintes, de cordeiros alimentados com diferentes proporções de feno de capim-buffel (Cenchrus ciliaris L.) e jurema-preta (Mimosa tenuiflora (Willd.) Poir.). O estudo foi desenvolvido na Universidade Federal de Campina Grande, Campus de Patos-PB. Foram utilizados 28 cordeiros, não castrados, com peso corporal inicial de 20 ± 2,49 kg. Os tratamentos foram as diferentes proporções dos fenos de jurema-preta (FJP) e feno de capimbuffel (FCB) na porção volumosa da dieta: 0% de FJP + 100% de FCB; 33% de FJP + 67% de FCB; 67% de FJP + 33% de FCB; 100% de FJP + 0% de FCB. Observou-se efeito quadrático para área de olho de lombo, conformação e medida GR ("grade rule"). As medidas espessura de gordura subcutânea e marmoreio apresentaram comportamento linear negativo, com a substituição do FCB pelo FJP. A substituição do FCB na proporção de 20 a 50% pelo FJP da porção volumosa na dieta de cordeiros permite uma boa conformação, área de olho de lombo e não constituintes da carcaça.

“…Tradicionalmente, os componentes não-carcaça (órgãos, as vísceras e outros subprodutos oriundos do abate dos animais) (Figura 1) eram utilizados para custear os gastos envolvidos durante o processo de abate. Todavia, sua importância comercial encorajou os produtores a adotarem maior eficiência sanitária para utilização de vísceras como opção alimentícia saudável para população, além de geração de receita (Bezerra et al, 2010;Moreno et al, 2011a;, haja visto que, de acordo com Silva et al, (2012), o comércio destes produtos representa cerca de 30% do valor do animal. A comercialização dos componentes não-carcaça além de contribuir com a nutrição humana (Honikel, Nollet e Toldra, 2010), reduz a poluição ambiental diminuindo os resíduos descartados nos abatedouros e confere um incremento na renda do produtor a partir da comercialização dessa porção edível que possui alto valor nutricional .…”
