Abstract

Dried coffee ground waste (Coffea arabica L.) (CGW) was given in digestion trials with castrated male sheeps in the percentages of; 0, 10, 20 and 30% in mixtures with 10 and 20% of cotton seed meal (Gossypium spp., seeds, solv. extd. grnd. IFN 4 - 11 - 744) and 90, 80, 70, 60 and 50% of pangola hay (Digitaria decumbens, hay, s.c. midbloom IFN 1 - 10 - 384). A control treatment was mede with 100% pangola hay. Increasing coffee grounds in the diets resulted in a linear decrease in dry matter consumption and a curvilinear increase in protein digestibilities and TDN values. Calculated TDN values of coffee grounds were respectively; 116.9 and 108.5% for 10 and 20% levels of cotton seed meal. CGW treated wtih 0, 0.5, 1, 2, 2.5, 4.5, 7.5, 8 and 10% of sodium hidroxide and urea at 2ml/20mg of protein, was evaluated by the €œin situ€ nylon bag technique. Treatments were significantly different (P < 0.01) and the extremes values were; 22.8 and 61.6%. CGW (20%) treated with urea (0.5%) in mixture with 60% pangola hay and 20% cotton seed meal, plus corn silage was given to dairy cows. MiIk production had an weekly reduction from 8.5 to 6.5, 4.6 and 4.2kg/day. Taken off CGW from the ration increased production to 6.5kg/day one week later.
