“…Those authors attributed this result to a decrease in gastrointestinal content at the time of slaughter. Findings similar to those observed in the current study for the hot and cold carcass yields of lambs receiving the corn grain-based treatment were obtained by Borges et al (2011), who examined the effects of different levels of substitution of corn grain for black oat on the performance of feedlot Texel lambs. The authors observed, for control treatment (no substitution; diet containing 84.75% whole grain corn) mean hot and cold carcass yields of 52.33% and 50.59%, respectively.…”

This study aimed to evaluate the effect of using different high-grain diets on the carcass characteristics and tissue composition of the meat of feedlot-finished lambs. Thirty-two male castrated Texel lambs born from single births and weaned at approximately 50 days of age were allotted to treatments that consisted of different unprocessed grains, as follows: corn grain, white oat grain, black oat grain, or grain of rice in the husk. The animals were slaughtered upon reaching the pre-established slaughter weight of 32 kg, which corresponds to 60% of the mature weight of their mothers. Lambs fed the high-corn grain diet had higher weights and yields of hot and cold carcass and larger loin-eye areas than those finished in the feedlot receiving high-grain diets based on white oat, black oat, or rice in the husk. Additionally, they had a higher degree of fatness and a thicker subcutaneous fat layer at slaughter, which lead to decreased cooler shrink loss. The neck, shoulder, ribs, and leg cuts were heavier in lambs fed the high-corn grain diet. By contrast, these lambs had a lower proportion of leg, more rib, and higher meat fat content, which may be undesirable for the consumer market. The use of high-corn grain diets, in comparison with high-grain diets based on black oat, white oat, and rice in the husk, may be recommended for finishing lambs in the feedlot when they are slaughtered at similar weights.

“…Resultados semelhantes foram observados por Borges et al, (2011), que avaliaram o desempenho de 24 animais (12 machos e 12 fêmeas) onde os animais do grupo 1 foram alimentados com uma dieta composta por 84,75% de milho grão e 14,25% de um concentrado proteico, mineral e vitamínico, a dieta fornecida assim como a utilizada nesse trabalho, possuía um alto teor de matéria seca (88,95%) afirmando a importância da mesma na variável supracitada.…”

“…Means followed by the same letter did not significantly differ by Tukey's test at 5% probability. The estimated TDN for ground corn is approximately 82.01% (CLARINDO et al, 2008) and its whole grain TDN may range from 77.21%-78.97% (BORGES et al, 2011). Thus, for some animal species, the partial or total replacement of corn by winter cereals without affecting performance and with increases in gross margins is possible (BORGES et al, 2011).…”

Morphological characteristics, dry matter production, and nutritional values of winter forage and grains were evaluated. This study was conducted from April 24, 2012 to November 7, 2013 in the Western Paraná State University (UNIOESTE), Marechal Cândido Rondon, Brazil. Pastures under one grazing and non-grazing conditions were evaluated under 120 kg N ha-1 fertilization split into two 60 kg N ha-1 treatments. Two pastures received 40 kg N ha-1 three times. IPR 126 oat, BRS Tarumã wheat, and IPR 111 triticale were the test crops. Topdressing with 40 or 60 kg N ha-1 did not change morphological characteristics until 60 d after sowing. Pastures under non-grazing that received 120 kg N ha-1 treatments were taller than the controls, whereas those under grazing that received 80 or 120 kg N ha-1 presented with higher leaf production than did the controls. Total average dry matter (DM) production in 2012 and 2013 was, respectively, 5,275 kg ha-1 and 6,270 kg ha-1 for oat, 3,166 kg ha-1 and 7,423 kg ha-1 for wheat, and 4,552 kg ha-1 and 7,603 kg ha-1 for triticale. Split N fertilization did not cause differences in the levels of crude protein (CP), neutral detergent fiber (NDF), and acid detergent fiber (ADF) in the forage. Nevertheless, increases in in vitro dry matter digestibility (IVDMD) were observed in oat and wheat receiving 60 kg N ha-1 during the first graze. IVDMD did not change in oat, wheat, and triticale forages receiving 80 or 120 kg N ha-1 during the second graze. Grazing did not affect the nutritional values of wheat and triticale grains, but reduced those of oat. Therefore, the results of the present study suggest that grazing lengthens the crop cycles, and so allow the staggered sowing of summer crops.
