Resumo: Forage conservation processes are fundamentally aimed at maintaining the nutritional quality of forages so that they can overcome the low availability and quality of roughage feed in unfavorable times. The objective of this study was to examine the effect of the number of layers of polyethylene film and storage time on the nutritional value of haylage of Tifton 85 grass (Cynodon spp cv. Tifton 85). Four and six layers of milky white polyethylene film were used in the wrapping of silage bales with a capacity of 400 kg (100 and 150 um in total thickness, respectively), for four different storage times (at baling and 30, 60, and 90 days). The experiment was laid out in a randomized-block design with four replicates, in a split-plot arrangement in time, in which the number of layers of polyethylene film that wrapped the haylage bales constituted the plots and the storage times the sub-plots. Neutral detergent insoluble protein (NDIP) levels were higher in the haylage wrapped with four layers of polyethylene film (35.8 g kg-1 CP). Storage time affected the neutral detergent fiber (NDF), acid detergent fiber (ADF), mineral matter (MM), NDIP, and lignin contents and in vitro dry matter digestibility (IVDMD). The ADF and lignin contents increased linearly, whereas IVDMD decreased linearly. Mineral matter showed a negative quadratic response. The NDIP and NDF contents exhibited a positive quadratic response. Storage time did not influence the dry matter (550.3 g kg-1), crude protein (102.3 g kg-1 DM), or acid detergent insoluble protein (28.9 g kg-1 CP) contents or in vitro NDF digestibility (582.1 g kg-1 DM). In conclusion, the number of layers of polyethylene film does not influence the nutritional value of Tifton 85 grass haylage. Storage for 90 days reduces the nutritional value of Tifton 85 grass haylage.

O objetivo do presente trabalho foi avaliar o efeito de número de camadas de filme de polietileno e tempos de armazenamento sobre o valor nutricional do pré-secado de capim Tifton 85 (Cynodon spp cv. Tifton 85). Foram utilizadas quatro e seis camadas de filme de polietileno branco leitoso no revestimento de silos-fardos com capacidade de 400 kg (100 e 150 um de espessura no total, respectivamente) e quatro diferentes tempos de armazenamento (enfardamento, 30, 60 e 90 dias). Utilizou-se o delineamento experimental em blocos casualizados, com quatro repetições, em esquema de parcelas subdivididas no tempo, sendo que o número de camadas de filme de polietileno que revestiram os fardos do pré-secado constituiu as parcelas e os tempos de armazenamento as subparcelas. Os teores de proteína insolúvel em detergente neutro (PIDN) foram superiores no pré-secado revestido com quatro camadas de filme de polietileno (35,8 g kg-1 PB). Houve efeito de tempo de armazenamento sobre os teores de fibra em detergente neutro (FDN), fibra em detergente ácido (FDA), matéria mineral (MM), PIDN, lignina e digestibilidade in vitro da matéria seca (DIVMS). Constatou-se acréscimo linear para os teores de FDA e lignina, e decréscimo linear para o teor de DIVMS. A MM apresentou comportamento quadrático negativo. Observou-se comportamento quadrático positivo sobre os teores de PIDN e FDN. Para os teores de matéria seca (550,3 g kg-1), proteína bruta (102,3 g kg-1 MS), proteína insolúvel em detergente ácido (28,9 g kg-1 PB) e digestibilidade in vitro da fibra em detergente neutro (582,1 g kg-1 MS) não houve influência de tempo de armazenamento. Coclui-se que o número de camadas de filme de polietileno não influenciou o valor nutricional do pré-secado de capim Tifton 85. O armazenamento durante 90 dias reduz o valor nutricional do pré-secado de capim Tifton 85.UEL2022-05-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de CampoAvaliado por paresPesquisa Empírica de Campo.application/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4505210.5433/1679-0359.2022v43n4p1865Semina: Ciências Agrárias; Vol. 43 No. 4 (2022); 1865-1874Semina: Ciências Agrárias; v. 43 n. 4 (2022); 1865-18741679-03591676-546Xreponame:Semina.
