Suplementación con borra de cerveza y maíz amarillo en engorde de toretes (Bos taurus L.) pastoreados en pradera native

The present research work was carried out in the Chirioco Canton Patamanta Community of the Municipality of Pucarani,with the objective of evaluating the effect of supplementation with beer and yellow corn on fattening of bulls grazedon native pasture, with three different rations during the time of transition (April, May and June). 9 Holstein mestizobulls of approximately 2 years of age have been used. The design used for increasing daily live weight and carcassperformance was randomized complete design. The average daily live weight increase was 1.21 kg for ration III), 0.99 kgfor ration II and 0.74 kg for ration I. The average requirement of the amount of water from a bull to produce 1 kg of meatwas of 95 L. The performance of the channel of bulls fed with different rations was 49.6%, 49.7% and 50.1% withrations I, II and III respectively. The reported values indicate that there are no significant differences, which can beattributed to the fact that the treatments were not homogeneous, since the bulls had a weight variation of 60 kg, as well asthe distance traveled for grazing.
