In vitro fermentation of diets containing sweet potato four as a substitute for corn in diets for ruminants
With the intensifcation of production systems, dairy cow feeding has undergone changes creating the need to increase substitute feed options, focusing on more efcient, modern, and sustainable alternatives.

| description | With the intensifcation of production systems, dairy cow feeding has undergone changes creating the need to increase substitute feed options, focusing on more efcient, modern, and sustainable alternatives. Few researches were carried out evaluating the inclusion of sweet potato four as an energy source in substitution of maize for ruminants. The aim of this study was to evaluate the in vitro gas production of ground corn replacement by sweet potato four at diferent levels. For in vitro gas production, four treatments were performed, consisting of corn replacement by sweet potato four at the levels of 0, 33, 66, and 100%, in a diet consisting of corn silage, soybean meal, and ground corn. In vitro incubations were conducted in sealed bottles containing 50 ml of the inoculum prepared using ruminal fuid and 0.5 g of each treatment. Gas production was determined in 96 consecutive hours. The cumulative gas production was greater when the corn was 100% replaced by SPF (224 [+ or -] 1.45 and 231.9 [+ or -] 1.45 ml/g DMi for 0 and 100% of replacement, P = 0.01). Degradation rates were 7.10, 7.59, 8.08, and 8.59 [+ or -] 0.06% per hour for the 0, 33, 66, and 100% replacement rates, respectively (P |

Fermentacao in vitro de dietas contendo farinha de batata-doce como substituto do milho em dietas para ruminantes Com a intensificacao dos sistemas de producao e o aumento das exigencias alimentares das vacas leiteiras criou-se a necessidade de diversificacao nas opcoes de alimentos, focando em alternativas mais efcientes, modernas e sustentaveis. Poucas pesquisas foram realizadas avaliando a inclusao da farinha de batata-doce como fonte de energia em substituicao ao milho para ruminantes. O objetivo deste trabalho foi avaliar a producao de gas in vitro da farinha de batata-doce (SPF) em substituicao ao milho moido em diferentes niveis. Para a producao de gas in vitro, foram realizados quatro tratamentos, com substituicao de milho por farinha de batata-doce a 0, 33, 66 e 100%, em uma dieta com silagem de milho, farelo de soja e milho moido. As incubacoes foram conduzidas em frascos selados contendo 50 ml do inoculo preparado utilizando o fluido ruminal, solucao tampao e 0,5 g de cada tratamento. A producao de gas acumulada foi maior na substituicao do milho pela SPF em 100% (224 [+ or -] 1.45 e 231,9 [+ or -] 1.45 ml/g MSi para as substituicoes 0 e 100%, P = 0,01). A taxa de degradacao foi 7,10, 7,59, 8,08 e 8,59 [+ or -] 0,06% por hora nas substituicoes 0, 33, 66 e 100%, respectivamente (P<0,001). Houve tambem diferenca (P = 0,002) no lag time, em que as dietas com maior inclusao de SPF tiveram tempo de colonizacao bacteriana menor Em conclusao, a farinha de batata-doce produziu mais gas e foi degradada mais rapidamente que o milho.
