Resumo: Feeding goats with calcium salts of fatty acids (CSFA) can supply ruminants with lipids, with minimal effects on ruminal fermentation and fiber digestibility. However, there is a shortage of information on the effect of CSFA on characteristics of rumen fermentation in grassland goats. Thus, the present study aimed to assess the addition of CSFA to concentrate on the parameters of rumen fermentation of grazing goats. Five rumen cannulated goats were distributed in a Latin square 5x5 design (treatments: 0%, 1.5%, 3.0%, 4.5% and 6.0% CSFA. The pH, ammonia N and volatile fatty acids (VFA) content were analyzed in the ruminal fluid at 0, 2, 4, 6 and 8 hours after concentrate supplementation. The pH and ammonia N concentration showed a linear effect with the addition of CSFA. There was no effect observed for the VFA molar concentration after grazing goats were fed with the experimental diet. In conclusion, further research is needed to investigate the addition of CSFA to goat diets because there is evidence that CSFA increases ruminal pH and decreases excess ruminal ammonia without changing the VFA concentration in the rumen fluid.

No entanto, há escassez de informações sobre o efeito da SCAG sobre as características da fermentação do rúmen em cabras de pastagem. Assim, o presente estudo teve como objetivo avaliar a adição de SCAG no concentrado de cabras na passagem sob nos parâmetros de fermentação ruminal. Cinco cabras canuladas do rúmen foram distribuídas em um quadrado latino 5x5 (tratamentos: 0%, 1,5%, 3,0%, 4,5% ou 6,0% de SCAG). O pH, N-amoniacal e ácidos graxos voláteis (AGV) foram analisado no liquido ruminal coletado às 0, 2, 4, 6 e 8 horas após a suplementação com concentrado. As concentrações de pH e N-amoniacal mostraram um efeito linear com a adição de SCAG. Não houve efeito observado para a concentração molar de AGV quando as cabras foram alimentadas com a dieta experimental. Em conclusão, são necessárias mais pesquisas para investigar a adição de SCAG às dietas de cabra, porque há evidências de que o SCAG aumenta o pH ruminal e diminui o excesso de amônia ruminal sem alterar a concentração de AGV no liquido ruminal.UEL2018-11-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapproachapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3139110.5433/1679-0359.2018v39n6p2621Semina: Ciências Agrárias; Vol. 39 No. 6 (2018); 2621-2634Semina: Ciências Agrárias; v. 39 n. 6 (2018); 2621-26341679-03591676-546Xreponame:Semina.
