“…Physical characteristics of meat, such as tenderness, color, and lightness, are important attributes at the time of purchase (Gois et al, 2017). In the present study, these variables did not show significant differences, because, regardless of the amount of forage or supplement consumed, the finishing system was the same.…”

This study aimed to identify the best green-leaf offerings of Urochloa brizantha cv. Marandu for pasture-finished lambs receiving protein-energy supplementation at the rate of 1.6% of their body weights (BW). The animals were assigned into four treatments, which consisted of varied green-leaf offerings, namely, 105, 90, 75, or 60 g of dry matter/kg of body weight (BW). Sixty-eight contemporary Texel × mixed-breed lambs with an average initial BW of 22.6 kg were used over two years of experiment. The experiment was set up in a completely randomized design, the data were evaluated by analysis of variance and the means were compared by Tukey's test at the 0.05 significance level. There was no significant effect of year neither interaction of year with green-leaf offer. There were significant effects of leaf offer on dry matter intake (DMI) with behavior of positively linear (p<0.05). There were significant effects of green-leaf offer on final BW and average daily gain, and lambs receiving of 75 g/kg green-leaf offer showed the highest ADG (179 g/d). There were no significant differences in the carcass, meat, and primal cuts between the groups of lambs receiving different herbage offerings. There were significant effects of leaf offer on slaughter weight, hot carcass weight, and subcutaneous fat thickness. Lambs receiving of 75 g/kg leaf offer showed the highest SFT (5.8 mm). Slaughter weight and hot carcass weight averaged 41.52 kg and 20.07 kg, respectively. We recommend the treatment with leaves offer of 75 g/kg BW of Marandu pasture for the finishing of lambs supplemented at 1.6% of BW.

“…Em geral, os principais fatores que influenciam as perdas por cocção são: o método de transferência de calor da superfície e temperatura interna da carne, pois afetam a quantidade de encolhimento do tecido conectivo, por meio da expulsão de fluidos da carne, e desnaturação das proteínas do musculo através da perda da capacidade de retenção da água (Gois, et al, 2017). Development, v. 9, n. 9, e736997887, 2020 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v9i9.7887 Ortiz Hernández e Rubio Lozano (2001) apresentaram efeito do sexo para as perdas por cocção apenas para a raça Rex, não sendo evidenciado diferenças para a raça Nova Zelândia, Chinchila e Califórnia.…”

Objetivou-se com essa pesquisa avaliar as características de carcaça e qualidade da carne de coelhos machos e fêmeas da raça Lionhead. Foram utilizados 20 coelhos de ambos os sexos, os quais constituíram os tratamentos. Os animais foram alimentados com ração concentrada, volumoso e água à vontade durante 60 dias. Houve pesagem semanal dos animais até o término do período de arraçoamento, quando então, foram submetido ao abate. O delineamento estatístico adotado foi inteiramente casualizado e aplicado o teste de Tukey para avaliação das médias. Os animais não apresentaram diferenças para peso vivo ao abate (1,499kg); peso do corpo vazio (1,00kg); peso da carcaça quente (0,798kg) e fria (0,791kg); rendimento de carcaça quente (53,23%) e fria (52,78%). As fêmeas apresentaram pesos do fígado (75,70g) e trato gastrointestinal (173,90g) superiores àqueles observados nos machos que foram 50,43g e 128,28g, respectivamente; no entanto, não foram verificadas diferenças para peso de coração, rins e pulmões. Não foram observadas diferenças para as variáveis de qualidade da carne: pH 0h (6,77) e 24h pós-abate (5,48); teor luminosidade (49,86), vermelho (4,70) e amarelo (5,78); perdas por cocção (22,26%) e força de cisalhamento (4,45 kgf/cm²). O sexo não influencia na qualidade da carne e características de carcaça de coelhos Lionhead. Coelhos machos e fêmeas da raça Lionhead apresentam potencial para fins de produção de carne, pois suas características de carcaça e qualidade da carne torna-a favorável ao comércio de produtos cárneos.

“…According to Dhanda et al (2003); Kannan et al (2003) and Santos et al (2008) found the more intense color, i.e., higher deposition and concentration of the pigment in the Longissimus muscle myoglobin in older sheep or with greater weights. According to Gois et al (2017) the meat presents a more Research, Society and Development, v. 9, n. 7, e56973717, 2020 (CC BY It is notable that the color is the most obvious freshness and quality index for the consumer. Usually, dark meats are rejected by the buyer, which links these to the old meat or derived from mature animals, so hard flesh.…”

It was proposed to verify the effect of the total substitution of soy by canola and crambe grains in the diet of crossbred lambs, in order to evaluate the chemical, instrumental and sensory characteristics of the meat of the animals fed under these grains. Twenty-three samples of the Longissimus lumborum muscle were used, from SRD lambs (mixed breed), non-castrated males, with an average age of 70 days, average initial body weight of 20.0 ± 4.0 kg. Of the 23 animals used, seven were destined for soybean diet, eight with canola grain and eight with crambe grain. The design was completely randomized with the factor evaluated as the total replacement (100%) of the ground soybeans considered control (GSO) by ground canola beans (GCA) and ground crambe beans (GCR). The sensory analysis data were submitted to Principal Component Analysis and the centesimal and instrumental analyzes were tested in orthogonal contrasts in relation to the different grains. The ration provided was in the form of a complete diet, with 75% concentrate and 25% roughage (Brachiaria brizantha cv Piatã hay). The results showed a higher moisture content in the meat of animals fed with canola, as well as in the instrumental characteristics (loss of cooking and intensity of red). For the other characteristics, there was no effect. The sensory analysis showed that the tasters preferred the meat of animals fed with soy and canola grains, pointing to the market potential. Canola and crambe grains can replace soy in the diet of lambs finished in feedlot, without affecting the centesimal, instrumental and mainly sensory characteristics of the meat, contributing as a new grain alternative in animal production.
