Summary: The objective of this study was to evaluate the effect of different forages preserved in silage form on eating behavior (feeding, rumination and leisure). Twelve Holstein lactating cows with a average 30 kg milk production were used. They were fed with three experimental diets composed by a combination of forages plus concentrate: (T1) 50 % of corn silage + 25 % of ryegrass silage + 25% of barley silage, (T2) 50 % of ryegrass silage +25 % of corn silage +25 % of barley silage and (T3) 50 % of barley silage +25% of corn silage + 25% of ryegrass silage. A latin square design 3 x 3 with extra period in a change over arrangement was used. Animals were submitted to eating behavior evaluation by visual observation every 14 days, during two consecutive days in four experimental periods. In the first day, the average number of chewing per ruminal bolus and the average time spending in the chewing per ruminal bolus were evaluated during three periods of two hours (8 - 10 hours; 14 - 16 hours; and 18 - 20 hours). In the second day, the eating behavior was visually determined during 24 hours with five minutes intervals. These data were used for to determine the eating and rumination spending time. There was not difference of experimental diets on spending time in feeding and rumination (minutes/day), eating efficiency and rumination (gDM/h and gNDF/h). Number of meals/day and number of rumination periods did not showed effect among different diets. It was observed 8.31 meals/day (in average), 36.20 minutes for spending time (in average), and 12.67 rumination periods/day. The eating behavior of the lactating cows was not influenced by the combination of the forages sources in the diets.

Foram utilizadas 12 vacas Holandesas em estágio de lactação com produção média de 30 kg de leite, alimentadas com três dietas compostas pela combinação de forragens mais concentrado, a saber: (1) 50% de silagem de milho + 25% de silagem de azevém + 25% de silagem de cevada; (2) 50% de silagem de Azevém + 25% de silagem de milho + 25% silagem de cevada e (3) 50% de silagem de cevada + 25% de silagem de milho + 25% silagem de azevém. As dietas foram suplementadas com concentrado e fornecidas na forma de dieta total. Utilizou-se um delineamento em quadrado latino 3 x 3 com período extra – changeover.Os animais foram submetidos à observação visual a cada 14 dias para avaliar o comportamento ingestivo, durante dois dias consecutivos nos quatro períodos experimentais. No primeiro dia de observação os animais foram avaliados durante três períodos de duas horas (8 às 10 h; 14 às 16 horas; e 18 ás 20 horas), medindo-se a média do número de mastigações merícias por bolo ruminal e a média do tempo despendido de mastigação merícica por bolo ruminal, utilizando-se cronômetro digital. No segundo dia, o comportamento ingestivo de cada vaca foi determinado visualmente, a intervalos de cinco minutos, durante 24 horas, para determinação do tempo despendido em alimentação e ruminação. Não se verificou diferenças para tempo despendido para alimentação e ruminação (min/dia), eficiência de alimentação e ruminação (g MS/h e g/FDN/h), das vacas em relação às dietas experimentais. Não houve diferenças para o número de refeições/dia, bem como para números de períodos ruminativos. Observou-se média de 8,31 refeições/dia, com duração média de 36,20 minutos e média de 12,67 períodos ruminativos/dia. O comportamento ingestivo das vacas em lactação não foi influenciado pelas combinações das fontes de volumosos nas dietas.UEL2004-05-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/222510.5433/1679-0359.2004v25n2p159Semina: Ciências Agrárias; Vol. 25 No. 2 (2004); 159-166Semina: Ciências Agrárias; v. 25 n. 2 (2004); 159-1661679-03591676-546Xreponame:Semina.
