Glicerina bruta em suplementos para bovinos de corte a pasto no período seco

Abstract: Resumo -O objetivo deste trabalho foi avaliar o efeito da substituição do milho pela glicerina bruta (GB) sobre os parâmetros nutricionais e o desempenho de bovinos de corte em pastagem de Urochloa brizantha 'Marandu', no período seco. Para a avaliação dos parâmetros ruminais, foram utilizados cinco bovinos da raça Nelore não fistulados, com peso corporal (PC) inicial de 331,7±29,6 kg, distribuídos em delineamento em quadrado latino 5x5. Para a avaliação do desempenho, foram utilizados 30 bovinos, com PC médio… Show more

“…However, the forage represents a large part of the diet, which favors ruminal buffering. Thus, glycerin had no effect on the ruminal pH, which has also been observed by Botini et al (2015) when replacing up to 100 % of maize by crude glycerin, offering 4 kg in the supplement/animal/day. Similar results were observed by Lage et al (2017), who evaluated the inclusion of 10% crude glycerin in fiber-based diets.…”

“…In the negative control, offering only mineral supplementation, the mean value of the experimental periods was below 5 mg of N-NH 3 /dL of ruminal liquid, below the critical value for the synthesis of microbial protein in animals on forage-based diets (LENG, 1990;DETMANN et al, 2009). In previous studies, Abo El-nor et al (2010), Peripolli et al (2014), and Botini et al (2015) evaluated the replacement of corn by increasing levels of crude glycerin and observed no effects on ruminal NH 3 concentrations. Serum blood glucose was not affected by protein-energy supplementation or the level of crude glycerin inclusion in supplements.…”

“…Tabela 5 -Desempenho Econômico (em R$) dos tratamentos com inclusão de coprodutos da agroindústria do biodiesel na alimentação de novilhas terminadas em pastagens. Para Botini et al (2015), o aumento da glicerina bruta nos suplementos para bovinos de corte em pastagem de brizantha marandu também foi positivo, mostrando que houve retenção de proteína no organismo dos 30 animais utilizados, proporcionando condições para que os mesmos não perdessem peso quando submetidos à suplementos concentrados formulados com Farelo de Soja e 20% de proteína bruta com 0, 33, 66 e 100% de Glicerina Bruta, em substituição ao milho, fornecidos na quantidade de 4,0 kg por animal por dia, indicando que as exigências de proteína nas dietas estiveram acima da mantença.…”

“…Nevertheless, nutritional and metabolic effects of total replacement of maize by CG have not been evaluated. There is still little information on the use of CG in protein-energy supplements for grazing beef cattle, particularly regarding the optimal level of dry ground maize replacement by CG (Botini et al 2015).…”
