Resumo: The objective was to test the hypothesis that ruminal inoculum obtained from slaughtered cattle can replace inoculum from cannulated cattle in trials evaluating animal feedstuffs through in vitro gas production and digestibility. Five adult Holstein × Zebu steers with ruminal cannula were used to collect and compare rumen liquid from in vivo and slaughtered animals. In vitro dry matter digestibility (IVDMD), in vitro neutral detergent fiber digestibility (IVNDFD) and ammoniacal nitrogen concentrations did not differ between inoculum sources (slaughtered × cannulated) for all byproducts and levels tested. Total in vitro gas production in the ruminal inoculum of cannulated animals was greater (P < 0.001) than slaughtered cattle for different levels of licuri cake. However, the greatest total concentrations of in vitro gases for slaughtered animals were observed when evaluating different levels of crude glycerin (P < 0.001). No differences were observed for diets containing castor bean meal (P >0.05). Thus, the ruminal inoculum obtained from the ruminal contents of slaughtered cattle can replace the use of fistulated animals and is a viable alternative to digestibility analysis. This approach is ethically more correct because it alleviates the suffering of animals by avoiding an invasive procedure.

Foram utilizados cinco novilhos adultos Holstein × Zebu com cânula ruminal para coleta e comparação de líquido ruminal provenientes destes animais in vivo e de animais abatidos. A digestibilidade in vitro da matéria seca (DIVMS) e da fibra em detergente neutro in vitro (DIVFDN) e as concentrações de nitrogênio amoniacal não diferiram entre fontes de inóculo (abatidos × canulados) para todos os subprodutos e níveis testados. A produção total de gás in vitro no inóculo ruminal de animais canulados foi maior (P < 0,001) comparado ao inóculo de animal abatido para os diferentes níveis de torta de licuri. No entanto, as maiores concentrações totais de gás in vitro foram observadas para animais abatidos quando o co-produto utilizado foram níveis de glicerina bruta (P 0,05). Assim, o inóculo ruminal obtido a partir do conteúdo ruminal de bovino abatido pode substituir o uso de animais fistulados, sendo uma alternativa viável para a realização da análise de digestibilidade. Esta abordagem é eticamente mais correta porque alivia o sofrimento dos animais evitando um procedimento invasivo.UEL2018-08-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3062910.5433/1679-0359.2018v39n5p2133Semina: Ciências Agrárias; Vol. 39 No. 5 (2018); 2133-2144Semina: Ciências Agrárias; v. 39 n. 5 (2018); 2133-21441679-03591676-546Xreponame:Semina.
