Comportamento ingestivo e parâmetros fisológicos de novilhos alimentados com tortas do biodiesel

Abstract: ADDITIONAL KEYWORDSHeart frequency. Respiratory frequency. Rectal temperature. RESUMOCom o objetivo de avaliar o potencial de tortas oriundas da produção de biodiesel (dendê, amendoim e girassol) em substituição ao farelo de soja, avaliou-se o comportamento ingestivo e parâmetros fisiológicos de novilhos Holandês x Zebu submetidos a dietas contendo estes subprodutos. Foram utilizados quatro novilhos Holandês x Zebu, fistulados no rúmen, mantidos em baias individuais e dispostos em um quadrado latino 4 x 4 repe… Show more

“…In this work, the feeding time was shorter than that described by Correia et al (2012), who studied Zebu steers fed diets with peanut cake replacing soybean meal in the concentrate and observed a feeding time of 330 min/day. The result was attributed to the concentrate fraction, which corresponded to 35% of the diet, whereas in the present study it corresponded to 60% of the total diet.…”

“…According to Dantas Filho et al (2007), increased levels of dietary NDF can limit the consumption of DM, and the physical regulation of DM consumption mainly occurs as result of the higher volume of cell wall material, as well as its low density and slower degradation, than of cell contents (NRC, 2001). In the present study, the increase in DM consumption may have resulted from the low granulometry of the PKM and its high transit rate, which reduced its physical effect consumption (GOMES et al, 2012).…”

“…4 Valor-P = probabilidade significativa ao nível de 5%. Correia et al (2012), ao avaliarem os parâmetros fisiológicos de novilhos Holandês x Zebu alimentados com dieta contendo torta de dendê, amendoim e girassol, não constataram efeito das tortas sobre a dieta testemunha constituída com farelo de soja em relação às variáveis temperatura retal e frequência respiratória.…”

“…A torta não sofre extração do óleo pelo uso de solventes, sendo constituída de maior teor de EE que não é fermentável no rúmen, o que poderia vir a reduzir o calor endógeno produzido pela fermentação ruminal, entretanto esta hipótese não ocorreu pela baixa ingestão da torta devido à alta relação volumoso:concentrado (70:30). Correia et al (2012), ao avaliarem os parâmetros fisiológicos de novilhos alimentados Arq. Bras.…”
