“…In ruminants, the time spent in feed and rumination activities is influenced by food characteristic, the fiber content and the presence of anti-nutritional compounds (NICORY et al, 2015). The average time spent on rumination was 503 min day -1 , which is between the range of 8 to 9 hours considered normal for the rumination activity (ALVES et al, 2010b;VAN SOEST, 1994).…”

The cottonseed cake is a co-product obtained after extraction of oil cottonseed, and because of their bromatological characteristics has potential use in ruminant feed, can increase the economy efficiency of animal production systems. The objective of this study was to evaluate diets with cottonseed cake in substitution of soybean meal through nitrogen balance, microbial protein synthesis and the ingestive behavior of lambs. Forty crossbred Santa Inês × Dorper non-castrated rams with average initial weight of 20.9 ± 2.5 kg were distributed into a completely randomized design with four treatments and ten replicates, and fed diets containing cottonseed cake in substitution of 0, 33, 66 and 100% of soybean meal. The diets were composed of corn, soybean meal, cottonseed meal and hay, with forage:concentrate reason of 50:50, isonitrogenous, with 14% crude protein. The animals were confined individually in pens with slatted floor, the evaluations of ingestive behavior, which included observations of the feeding, rumination and idle times were performed in a period of 24 hours, in 5-minute intervals. At 82 days of experiment, a spot urine sample was collected from all animals to quantify the concentrations of nitrogen, creatinine, allantoin, uric acid, xanthine and hypoxanthine in the urine. The data were subjected to variance analysis and regression, adopting α= 0.05. There was no significant difference between treatments for nitrogen balance, the synthesis of nitrogen compounds, and microbial efficiency. In addition, there was no effect of replacing soybean meal by cottonseed meal on feeding behavior of animals. Cottonseed cake can replace soybean meal up to 100% in diets for lambs. ResumoA torta de algodão é um coproduto obtido após a extração do oléo do caroço de algodão, e devido às suas características bromatológicas apresenta potencial de uso na alimentação de ruminantes, podendo aumentar a economicidade dos sistemas de produção animal. O objetivo com este estudo foi avaliar dietas com torta de algodão em substituição ao farelo de soja sobre o balanço de nitrogênio, a síntese de proteína microbiana e o comportamento ingestivo de cordeiros. Foram utilizados quarenta cordeiros mestiços Santa Inês x Dorper não castrados, com peso médio inicial de 20,9±2,5 kg, distribuídos em um delineamento experimental inteiramente casualizado, com quatro tratamentos e dez repetições, alimentados com dietas contendo torta de algodão em substituição à 0, 33, 66 e 100% do farelo de soja. As dietas foram compostas de milho, farelo de soja, torta de algodão e feno, com razão volumoso:concentrado de 50:50, isonitrogenadas, com aproximadamente14% de proteína bruta. Os animais foram confinados em baias individuais com piso ripado, as avaliações do comportamento ingestivo, que incluíram observações dos tempos de alimentação, ruminação e ócio foram realizadas em um período de 24 horas, em intervalos de 5 minutos. No 82º dia do período experimental, foram coletadas amostras de urina de todos os animais para quantificar as concentra...

“…Diets with lower percentages of NDF provide a higher dry matter intake, requiring a shorter total feeding time per kg of DM by the animal, which indicates better feed and rumination efficiencies as a function of DM intake and according to Nicory et al (2015) rumination efficiency is an important mechanism to evaluate the use of low-digestibility feeds.…”

The aim of this study was to evaluate the effects of protein-energy or mineral supplementation on the ingestive behavior of dairy steers on pasture in the post-weaning phase during the rainy to dry season transition. Twenty-two ½ Holstein–Zebu dairy steers with an average initial body weight of 234 ± 16 kg were distributed into a completely randomized design into two groups: protein-energy supplementation and mineral supplementation offered ad libitum. The steers receiving protein-energy supplementation showed higher (P < 0.05) intake of dry matter (DM) and neutral detergent fiber (NDF) than those fed diets composed of mineral salt only. In addition, the animals that received protein-energy supplementation had longer period in grazing and spent on average more time per period eating at the trough (P < 0.05), however no significant differences were observed in the time per period in rumination and time per period in idle (P > 0.05). The supply of protein-energy supplement does not change the feeding behavior, except for an increase in the time spent feeding at the trough. The intake of protein-energy supplement improved the of DM and NDF feed efficiencies in grazing cattle during the rainy to the dry season transition.

“…To achieve this purpose, feeding strategies should be better studied aiming to stabilize the supply of this product in the market, which compromises the productive chain of the region. Because of this situation, the use of the feedlot for the ovine species has emerged as a viable option due to the irregular rainfall that reduces the availability of forage, making this an attractive alternative if food sources available in the region are used (Parente et al, 2009, Nicory et al, 2015.…”

ABSTRACT. The objective was to evaluate the correlation between performance and feeding behavior of feedlot castrated Santa Inês lambs fed without roughage diet, weighing 20 ± 1.8 kg and four months of age (± 0.34). A completely randomized design was adopted. Correlations were obtained by Pearson's linear correlation analysis and the t test, and processed on SAS software (version 9.2). The variables number of rumination chews per cud, number of cuds ruminated per day, speed of each chew, and number of rumination cuds per day were positively correlated with the variation in body weight (p < 0.05). For number of cuds ruminated per day, a positive correlation was found with the variations in body weight. Initial and final body weights were positively correlated with the feed and rumination efficiencies of the lambs feeding behavior and with the time per period spent feeding and performing other activities. Feeding time had a positive correlation with variation in body weight per day and the relative variation in body weight. Rumination was positively correlated with performance variables. The correlations show that there is influence between eating behavior and performance.Keywords: concentrate, intake, weight gain, sheep.Correlação entre o desempenho e o comportamento alimentar de cordeiros confinados recebendo dieta sem volumoso RESUMO. Objetivou-se estimar correlações entre desempenho e comportamento alimentar de cordeiros castrados da raça Santa Inês alimentados sem volumoso, com peso médio de 20± 1,8 kg e quatro meses de idade (± 0,34). O delineamento inteiramente casualizado foi adotado. As correlações foram obtidas pela análise de correlação linear de Pearson e o teste t, e processados no software SAS (versão 9.2). Os variáveis números de mastigações ruminação por bolo alimentar, número de bolo alimentar ruminado por dia, velocidade de mastigação, e número de bolo alimentar por dia foram positivamente correlacionados com a variação no peso corporal (p < 0,05). Para o número de bolo alimentar ruminado por dia, a correlação positiva foi encontrada com as variações de peso corporal. O peso corporal inicial e o final foram positivamente correlacionados com eficiências da alimentação e da ruminação do comportamento alimentar dos cordeiros, e com o tempo por período de alimentação e de outras atividades. O tempo de alimentação apresentou correlação positiva com a variação de peso corporal por dia e a variação relativa no peso corporal. O tempo de ruminação foi positivamente correlacionado com variáveis do desempenho. As correlações mostram que há influência entre comportamento alimentar e desempenho.Palavras-chave: concentrado, ingestão, ganho de peso, ovinos.
