Two experimentswere carried out with the objective of evaluating the performance and carcasstraits of growing and finishing pigs fed rations with sticky coffee hull silage.In experiment 1, the coffee hulls were ground through a 4-mm screen and ensiledwith 30% water and enzymatic-bacterial inoculant and evaluated in digestibilitytrial with 15 crossbred pigs distributed in a completely randomised design.Overall, the ensiling process did not improve the digestibility of the stickycoffee hulls. In experiment 2, it was used 60 pigs (32.52 to 59.58 kg) in thegrowing phase and 55 pigs (61.70 to 90.27 kg) in the finishing phase, distributedin a completely randomised design with five diets (0, 4, 8, 12 and 16% of stickycoffee hull silage) and six replicates. In the growing and finishing phase,inclusion of levels of sticky coffee hull silage did not affect feed intake,weight gain, and plasma urea nitrogen. However, in the finishing phase, feedconversion improved as the levels of sticky coffee hull silage increased. Responsesby backfat thickness and marbling were quadratic, whereas empty stomach weightincreased linearly when sticky coffee hull silage was included in the diet.Sticky coffee hull silage has good nutritional value and if used in levels upto 16% of the diet, it does not impair performance of pigs in the growing andfinishing phases and it results in leaner carcasses. However, the economic feasibilityof its use depends on the price relationship of this by-product with the otherfeedstuffs.
