“…The slaughter age of lambs finished in feedlot and semi-feedlot in this experiment corroborates with the first two slaughter ages of feedlot Santa Inês lambs studied by Queiroz et al (2015), which were 145, 156 and 190 days, with live weight of 27.14, 33.84 and 34.85 kg, respecitvely. This indicates that the weight gain verified in this experiment fits the breed standards used, which are breedings that allow for higher meat production, muscle development and carcass conformation, being of great importance and capable of raising productivity in a shorter period of time.…”

“…Nevertheless, loin muscle and fat proportion were influenced by sex; females presented lower muscle proportions and higher fat proportions in relation to males (Table 5). Queiroz et al (2015) found a muscle, bone and fat proportion of 55.9, 20.9 and 23.6, res pectively, in male, uncastrated Santa Inês lambs slaughtered with a 3mm SFT. It is worth highlighting that the lambs were fed a high-concentrate diet, which favors a higher fat deposition in the carcass.…”

“…LEA measurement is important to predict carcass yield because this index correlates with carcass meat percentage, and subcutaneous fat thickness measure, assessed in muscle Longissimus dorsi, highly correlates with carcass fat composition (Cartaxo & Sousa, 2008). Queiroz et al (2015) found higher UFT and SFT values (2.97 mm and 3.02 mm, respectively) in Santa Inês lambs finished in feedlot and slaughtered upon reaching the average live weight of 33 kg, with average age of 155 days. Grandis et al (2016), assessing male, uncastrated Santa Inês lambs fed different amounts of soybean cake, observed average mean value for LEA of 14.60 cm 2 , and 2.53 mm for SFT.…”

This study aimed to assess the influence of lamb finishing systems on zootechnical performance, as well as on carcass and meat quality. The experiment was conducted at the APTA’s experimental farm. Thirty-three lambs were used – both sexes, initial age of 90 ± 3 days, Texel with Santa Inês, each animal being one experimental unit, with 6 males and 5 females per treatment. Treatments consisted of: lambs finished on pasture, in semi-feedlot or in feedlot. The lambs were slaughtered with average live weight of 35 kg. Weight gain and carcass measures were taken by ultrasound. After slaughter, carcass conformation and yield, pH, temperature, color, water retention capacity and tenderness were measured. Animals finished on pasture had lower weight gain, were slaughtered at an older age, with lighter carcass weight, smaller loin area, lower shank compactness index, besides lighter shoulder and shank weights, compared to the other production systems (p < 0.05). There was no difference between the semi-feedlot and the feedlot systems for the assessed characteristics. In conclusion, production systems affect animal performance, as well as carcass and meat quality, especially when it comes to important production aspects, such as slaughter age and yield of premium cuts.

“…Estudos demonstram que, o GMD esperado em animais criados a pasto ou seja com maior teor de volumoso na dieta e suplementados é entre 150-200 g dia -1 (Carvalho et al, 2007;Fernandes et al, 2011;Ribeiro, 2010), enquanto cordeiros confinados, alimentados com maior proporção de concentrado, espera-se ganhos de 350-450 g dia -1 (Poli et al, 2008;Ribeiro et al, 2009 Tabela 3), pois os mesmos apresentaram crescimento uniforme das medidas de comprimento (comprimento corporal) e altura (altura de anterior e posterior). Queiroz et al (2015) observaram AOL de 10,6 ± 1,04 cm 2 para animais com 2 mm de ESPG, trabalhando com cordeiros Santa Inês com aproximadamente 100 dias de idade, alimentados com feno de aveia e concentrado a base de farelo de milho e soja.…”

Palavras Chave: Extrusão. Nutrição. Ovis aries. Ruminantes.Extruded ration with different roughage: concentrate ratios for growing sheep ABSTRACT The provision of total ration to the animals favors a better roughage: concentrated -+985 ratio, preventing the animal from establishing an undesired proportion between the food and ensuring that it meets its nutritional requirement for maintenance and production. The objective was to compare the intake and digestibility of dry matter and nutrients, and the productive and physiological performance of lambs fed with extruded ration in different roughage (R): concentrated (C) ratios, being 30R:70C and 70R: 30C. The experiment was carried out at the Federal University of Uberlândia (UFU), Experimental Farm Capim Branco, between October 2016 and February 2017. For the study of consumption and digestibility were used 10 lambs, mixed races (Santa Inês x Dorper), aged between four and five months, and mean weight of 25 kg. The animals were placed in metabolic cages equipped with feeder, drinking fountain, salt shaker and wooden slatted floor. The treatments consisted of extruded ration in 30R: 70C and 70R: 30C ratios, completely randomized to two treatments and five replicates. The means of treatments were evaluated by the Tukey test at a significance level of 5%. Consumption and digestibility of dry matter and nutrients, water consumption by animals, and nitrogen balance were analyzed. The 30R: 70C treatment showed lower intake of dry matter, crude protein, neutral detergent fiber, acid detergent fiber, hemicellulose and total digestible nutrients, and presented higher dry matter and neutral detergent fiber digestibility. It also presented lower intake and faecal excretion of nitrogen, consequently establishing a greater relation between nitrogen retained and ingested nitrogen. For the study of productive and physiological performance, 30 lambs were used, with age of three months and average weight of 20kg. The animals were allocated in collective stalls, being six stalls with five animals each, with a feeder, drinking fountain, salt shaker and suspended wooden floor. The treatments consisted of extruded ration in 30R: 70C and 70R: 30C ratios, completely randomized to two treatments and 15 replicates. The means of the treatments were evaluated by the Tukey test and a regression study at the significance level of 5%. The dry matter intake, ingestive behavior, ruminal movement, body growth, weight gain, ultrasound carcass evaluation, concentration of energy metabolic, protein and mineral metabolites, and blood concentration of enzymes that indicate hepatic and muscular activity were analyzed. There was lower CMS for 30R: 70C treatment, and reduction of CMS relative to body weight at the end of the experiment. The animals presented a reduction in the time spent with rumination and total chewing and also lower ruminal movement for the two rations analyzed during the experimental period. However, at the beginning of the experiment there was less time spent with rumination and tota...
