Resumo: | The objective of this study was to evaluate the ingestive behavior of lactating dairy cows grazing on tropical pasture supplemented with different levels of crude glycerin in the diet. Ten lactating cows, ¾ Gir x ¼ Holstein Dairy cows, primiparous, and 109 ± 24 days of lactation, mean age 30 ± 6 months and mean body weight of 426.2 ± 68.29 kg, distributed into five treatments, in double (5x5) Latin square design, were used. The treatments consisted of inclusion levels of crude glycerin in the diet (0.0, 4.5, 9.0, 13.5, and 18.0% dry matter basis). The behavior evaluation was performed on the 14th day of each period, with observations every five minutes for a period of 24 hours. The results were analyzed statistically using analysis of variance and regression at 5% probability. For the grazing time, other activities, rumination, feeding trough, the number of grazing periods, other activities, rumination and feeding trough, as well as bit rate, number and time of chews per bolus, and efficiencies of eating and ruminating were not significant differences among crude glycerin levels in the diet (P>0.05). The inclusion of crude glycerin in diets for lactating cows in tropical pastures does not promote changes in ingestive behavior. The absence of negative effects related to the use of this byproduct in substitution of corn in these conditions allows its use in up to 18% crude glycerin in diets for dairy cows without changing the behavioral parameters related to food intake. |

Objetivou-se com este estudo avaliar o comportamento ingestivo de vacas lactantes mantidas em pastagem tropical suplementadas com diferentes níveis de glicerina bruta na dieta. Foram utilizadas 10 vacas lactantes, ¾ Holandesa x ¼ Gir Leiteiro, primíparas, com 109 ± 24 dias de lactação, idade média de 30 ± 6 meses e peso corporal médio de 426,2 ± 68,29 kg, distribuídas em cinco tratamentos, utilizando-se dois quadrados latinos cinco por cinco (5x5), Os tratamentos foram constituídos pelos níveis de inclusão de glicerina bruta na dieta (0; 4,5; 9; 13,5 e 18%; base matéria seca). A avaliação do comportamento foi realizada no 14º dia de cada período, sendo feitas observações a cada cinco minutos por um período de 24 horas. Os resultados foram analisados estatisticamente por meio de análises de variância e regressão a 5% de probabilidade. Para os tempos de pastejo, outras atividades, ruminação, alimentação no cocho, número de períodos de pastejo, outras atividades, ruminação e alimentação no cocho, assim como taxa de bocado, número de mastigações merícicas e tempo por bolo alimentar, e as eficiências de alimentação e ruminação não foram verificadas diferenças entre os níveis de glicerina bruta na dieta (P>0,05). A inclusão de glicerina bruta na dieta de vacas lactantes em pastagens tropicais não promove variações no comportamento ingestivo. A ausência de efeitos negativos relacionados ao uso deste coproduto em substituição ao milho nestas condições permite a sua utilização em até 18% de glicerina bruta em dietas para vaca leiteiras sem alterar os parâmetros comportamentais relacionados à ingestão de alimentos.UEL2013-06-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpesquisa de campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1104710.5433/1679-0359.2013v34n3p1339Semina: Ciências Agrárias; Vol. 34 No. 3 (2013); 1339-1352Semina: Ciências Agrárias; v. 34 n. 3 (2013); 1339-13521679-03591676-546Xreponame:Semina.
