Abstract


This study aimed to evaluate the effects of includingsun-dried banana peel in diets for F1 Holstein x Zebu cows on intake, digestibility and milk production. Diets were composed of 0, 15, 30, 45 and 60% replacement of sorghum silage with banana peel provided to 10 cows in two simultaneous 5 x 5 Latin squares, with the experiment divided into five periods of 16 days. The dry matter intake showed a quadratic effect with maximum level at 38.30% substitution as well as intake of crude protein expressed in kg-1 day and percentage of body weight, with maximum at the levels of 50.09 and 45.69% inclusion of the peel, respectively. The intake of neutral detergent fiber and the digestibility of neutral detergent fiber and crude protein showed a decreasing linear effect. Variation in weight and body condition score, milk production and feed conversion were not affected. The replacement of 60% sorghum silage with banana peel represents a viable alternative as it causes no change in cows with average production of 16.49 kg milk with 3.5% fat day-1, reducing feeding costs.
