- Replacement of corn with pre-dried cassava root silage in the diet for dairy goats Maria Josilaine Matos dos Santos Silva Edneide Rodrigues da Silva Fátima Lira dos Santos Cinthya Mikaelly da Silva Santos Paulo Otávio Silva Cavalcante Kedes Paulo Pereira Vitor Visintin Silva de Almeida Dorgival Morais de Lima Agrociencias goat milk root silage Manihot esculenta ingestive behavior The objective of this study was to evaluate the effect of replacement of corn with pre-dried cassava root silage (CRS) on intake, ingestive behavior, production and composition of goat milk. Five lactating Saanen goats were used, with 42.5 ± 4.2 kg body weight and production of 2 kg milk day-1, distributed in a 5 x 5 Latin square with five treatments: 0, 28.6, 58.0, 81.6 and 100% replacement of corn with CRS in the diet dry matter. Goats were monitored for five periods of 15 days each. The intake of dry matter, crude protein and neutral detergent fiber decreased linearly (p <0.05) with the replacement of corn with CRS. Feeding (348.5 ± 62.1 min.) and rumination (468.8 ± 83.8 min.) times were not influenced (p >0.05) by the replacement of corn with CRS, but the ingestion and rumination efficiencies had a linear increase (p > 0.05). Milk production (2.17 ± 0.45 kg day-1), fat (3.49 ± 0.42%), protein (3.11 ± 0.13%) and lactose (4.47 ± 0,11%) of goat milk were not influenced (p >0.05) by the replacement of corn with CRS. Therefore, it is recommended the total replacement of corn with pre-dried cassava root silage in the diet for dairy goats with an average production of 2 kg day-1. 2022 artículo científico 1806-2636 https://www.redalyc.org/articulo.oa?id=303171455048 https://www.redalyc.org/journal/3031/303171455048/ https://www.redalyc.org/journal/3031/303171455048/html/ https://www.redalyc.org/journal/3031/303171455048/303171455048.epub https://www.redalyc.org/journal/3031/303171455048/movil 10.4025/actascianimsci.v44i1.55947 en http://www.redalyc.org/revista.oa?id=3031 Acta Scientiarum.
