“…These findings can be considered satisfactory and are explained by the energy concentration of the diet, as well as the genetic potential of the lambs, because all animals had excellent origins. In their study of Santa Inês lambs fed a similar diet, Urano et al (2006) found average to better feed conversion obtained in the present study (3.5).…”

-The objective of this study was to evaluate the performance, qualitative, morphometric and quantitative carcass traits of Santa Inês lambs of different frame sizes finished in a feedlot. Twenty 120-day-old intact lambs with a 25.0±3.1 kg average body weight at the beginning of the experiment were used. Lambs received a diet containing 17% crude protein and 2.70 Mcal/kg dry matter. Frame size influenced performance and tissue composition in the carcasses of the lambs. Lambs with large frame sizes showed better carcass conformation compared with those of medium-sized frames. Frame size was found to have a significant effect on rump perimeter. Large-framed lambs showed higher compactness on the carcass index and carcass dressing area compared with medium-framed lambs. The cuts of large-framed lambs weighed more than those of mediumframed lambs. However, no significant differences were found in dressing.

RESUMO -Objetivou-se com este estudo avaliar os efeitos da adição de bicarbonato de sódio ou de fontes de calcário com diferentes granulometrias na ração, associadas ou não a monensina sódica, sobre o desempenho e as características de carcaça de cordeiros confinados recebendo dietas contendo alta proporção de concentrado. Quarenta e dois cordeiros Santa Inês com peso inicial de 21 ± 3 kg e 88 ± 5 dias de idade foram distribuídos em blocos completos casualizados em arranjo fatorial 2 × 3, com seis tratamentos e sete repetições. Os animais foram alimentados com rações contendo 90% de concentrado, 10% de feno de "coastcross", uma fonte de calcário (calcário calcítico ou calcário calcítico tipo filler) ou bicarbonato de sódio (NaHCO 3 ), com ou sem adição de monensina sódica (30 mg/kg da MS). Não foi observada influência dos agentes tamponantes no consumo de matéria seca e no ganho de peso médio diário. Entretanto, a conversão alimentar dos animais alimentados com as rações contendo monensina sódica (3,32 kg MS/kg de ganho) foi melhor que naqueles que consumiram as rações sem esse aditivo (3,58 kg MS/kg de ganho). Não houve efeito dos agentes tamponantes nos parâmetros de carcaça avaliados, observando-se valores médios de 50,4%; 2,4%; 13,9 cm 2 e 1,9 mm para o rendimento de carcaça quente, a perda por resfriamento, a área de olho-de-lombo e a espessura de gordura, respectivamente. A adição de monensina melhora a conversão alimentar e pode aumentar a rentabilidade do sistema de produção de cordeiros confinados.Palavras-chave: fontes de calcário, ionóforos, monensina sódica, pH, rúmen, terminação Performance and carcass characteristics of feedlot lambs fed high grain diets with buffer compoundsABSTRACT -The objective of this study was to assess the effects of adding sodium bicarbonate or limestone sources with different particle sizes to the diet, and their interaction with sodium monensin, on the performance and carcass characteristics of feedlot lambs fed fed high grain diets. Forty two Santa Ines lambs were used with 21 ± 3 kg initial average body weight and 88 ± 5 days old in feedlot, placed a randomized complete block design in a 2 × 3 factorial arrangement with six treatments and seven replications. Animals were fed diet containing 90% concentrate, 10% "coastcross" hay, with one source of limestone (limestone or "filler" limestone) or sodium bicarbonate (NaHCO 3 ), with or without monensin (30 mg/kg DM). No influence was observed of the buffering agents on dry matter intake or average daily gain. However, the feed conversion of the animals fed diet containing sodium monensin (3.34 kg DM/kg gain) was better than those fed diets containing monensin (3.32 kg DM/kg gain) compared to diets without monensin (3.58 kg DM/kg gain). There was no effect of the buffering agents on the carcass characteristics assessed: the mean values were 50.4%, 2.42%, 13.9 cm 2 and 1.9 mm hot carcass weight, chilling losses, longissimus muscle area and fat thickness, respectively. Adding monensin to the diet improves feed conversion and m...
