Mixed Ration Silage Containing Tanzania Grass and Babassu By-Products for Dairy Cows

The use of mixed ration silage (MRS) provides animals with a diet formulation that meets their nutritional requirements. This study aimed to evaluate the fermentative profile, losses, chemical composition and in vitro dry matter digestibility silages, including babassu by-products as feed alternative for dairy cows. A completely randomized design was used, four treatments five replications, which were composed TGS: Tanzania grass silage; MRSS: corn soybean meal; MRSF: corn, meal flour; MRSC: cake. There significant difference between MRS TGS (p < 0.05) variables’ pH, gas (GL) effluent losses (EL), recovery (DMR), water-soluble carbohydrates (WSC), (DM), crude protein (CP) total digestible nutrients (TDN). no statistical buffer capacity (BC), acid detergent lignin, hemicellulose, ether extract (EE) aerobic stability. However, ammonia nitrogen (NH3-N) non-fibre carbohydrate (NFC) content, lower values observed 0.001). by-products, cake flour, can replace by up 50% grass, meeting requirements
