Consumo, digestibilidade dos nutrientes, produção e composição do leite de vacas alimentadas com resíduo de cervejaria fermentado

Abstract: Objetivou-se avaliar a inclusão de 0, 5, 10 e 15% do resíduo de cervejaria fermentado (RCF) nas rações de vacas leiteiras sobre o consumo e coeficiente de digestibilidade total (CD) dos nutrientes, produção e qualidade do leite. Foram utilizadas 28 vacas da raça Holandesa, com aproximadamente 101  21 dias de lactação, e peso corporal médio de 612  110 kg, alimentadas com silagem de milho, silagem pré-secada de azevém, RCF e concentrado. Foi utilizado o delineamento inteiramente casualizado. Os dados de consu… Show more

“…0.80% BW of NDF intake. Lack of differences were also reported in dairy cows by Geron et al [ 20 ] (inclusion up to 15% of fermented brewer’s residue in diets containing also corn silage, pre-dried ryegrass silage and concentrate), and other authors using WBG up to 16% [ 21 ] and 10% on a DM basis [ 22 ]. As DMI was not affected by treatments, changes in NDF consumption as % BW reflected changes in NDF ration concentration, hence that the high levels of daily DMI recorded (4.03% BW) and the trend to reduce DMI as WBG increased would lead to speculate that animals were within the chemostatic intake regulation range.…”

“…Geron et al (2010) also showed an increase in EE intake (g kg -0.75 d -1 ) of around 8% when lactating cows were fed 15% brewer's grain silage compared with cows fed a diet with 0% brewers' grain silage. Mertens (1992) suggested that NDF intake of an animal up to 12 g kg -1 d -1 of body weight is the main mechanism of physical regulation of DM intake.…”

“…However, data using dried brewers' grains (DBG) in lactating cow diets are scarce. The use of brewer waste in the wet and fermented forms for lactating cows have showed positive results, because it does not affect the dry matter intake (Chiou et al, 1998) and milk production (West et al, 1994;Firkins et al, 2002;Geron et al, 2010;Imaizumi et al, 2015), but causes an increase in fat contents (Davis et al, 1983) and milk protein (West et al, 1994).…”

“…As silagens pré-secadas de gramíneas e leguminosas de clima temperado, apresentam em sua composição, menores teores e melhor qualidade da fração fibrosa, quando comparadas à pré-secados de forrageiras tropicais (Pereira et al 2003). O teor proteico de pré-secados a partir de leguminosas, se equipara aos dos fenos (NRC, 2000;Valadares Filho et al 2006;Geron et al 2010). Pré-secados feitos de maneira adequada, apresentam aroma agradável e são mais palatáveis, tal fato pode explicar, o aumento no consumo de matéria seca, quando esse tipo de volumoso é fornecido aos animais (Ensminger et al 1990).…”
