Eficiência bioeconômica de bovinos de corte em confinamento

Abstract: RESUMOObjetivou-se avaliar o consumo de matéria seca, o ganho de peso total e a eficiência bioeconômica de bovinos de corte terminados em confinamento com diferentes pesos corporais ao início do confinamento nos períodos de seca e de chuvas. Registros de CMS, ganho de peso total (GPT), conversão alimentar (CA), eficiência alimentar (EA), tamanho de lote e tempo de permanência (TP) no confinamento de 13.686 bovinos de corte machos com predominância de sangue nelore terminados no ano de 2009, foram utilizados pa… Show more

“…The period an animal is kept in the production system is a key factor for efficiency (Nichelle et al, 2015). The pre-weaning development of male calves in intensive systems, has an impact on the efficiency of transformation of feed into weight gain (Gottschall et al, 2007;Vaz et al, 2012).…”

“…Lower body weights of males born at the beginning of grazing forage for high performance delay the achievement of the target weight and degree of finishing. These factors may determine an extended stay of the animals in the system or even the use of feedlots for finishing (Mello et al, 2009), which affects the production efficiency of the system (Nichelle et al, 2015).…”

“…Entretanto, a conversão alimentar foi melhor nos animais recebendo o resíduo amonizado com 8% de ureia em relação a 4 e 6% (P<0,05) (Tabela 4). Como o resíduo de algodoeira é barato na região, não se justifica priorizar a conversão alimentar em detrimento da taxa de ganho de peso diário, exceto se o custo do alimento aumentar significativamente (CERVIERI, 2012;NICHELE et al, 2015).…”

“…In addition, the MBNI, also known as nutritional efficiency (EUCLIDES FILHO et al, 2001;NICHELE et al, 2015;PAZDIORA et al, 2013), was defined by the equation MBNI = (3.97 x ADG) + (-0.06 x DMI). Higher MBNI values indicate more efficient animals because the canonical coefficient associated with ADG was positive and the canonical coefficient associated with DMI was negative.…”

“…Achieving the highest bioeconomic efficiency is primarily associated with the conversion of ingested food into the production of animal protein. In this respect, some studies determined the biological efficiency of confined cattle using different parameters and different statistical analytical methods to identify the best discrimination between different groups (MELLO et al, 2010;NICHELE et al, 2015;PAZDIORA et al, 2013).…”
