CHEMICAL COMPOSITION AND ANTINUTRITIONAL FACTORS IN SILAGES WITH BYPRODUCTS OF COFFEE PROCESSING

Abstract

The shortage of fodder in some regions of Brazil have been blamed for the low productivity of cattle. Aiming to alleviate this problem, several alternatives have been proposed, such as the use of agroindustrial residues, such as coffee husks. Thus, this study aimed to evaluate the chemical composition and antinutritional factors of silages produced with by-products of coffee processing. To achieve this goal were evaluated 13 treatments (T) with the use of wet coffee pods (CCU), dried coffee husk (CCS), with or without the use of molasses to 5% (M) and with or without the use inoculum of Lactobacillus plantarum (I), as follows: T1 (CCU 100%), T2 (90% CCU + 10% CCS ), T3 (80% CCU + 20% CCS), T4 (60% CCU + 40% CCS) , T5 (85% CCU + 10% CCS + 5% M), T6 (90% CCU + 10% CCS + I), T7 (75% CCU + 20% CCS + 5% M), T8 (80% CCU + 20% CCS + I), T9 (55% CCU + 40% CCS + 5% M), T10 (60% CCU + 40% CCS + I), T11 (85% CCU + 10% CCS + 5% M + I) T12 (75% CCU + 20% CCS + 5% M + I), T13 (55% CCU + 40% CCS + 5% M + I). Once the treatments prepared, these prototypes were stored in silos made of PVC measuring 250 mm in diameter and 750 mm in height over a period of 60 days. Analyzes of chemical composition and antinutritional factors were performed in silages. Given the results, it is concluded that the silages from coffee husks have potential for feeding ruminants, however, the presence of some chemical compounds adversely affects the nutritional value of coffee pods and their inclusion in the diet of ruminants must be performed with caution.
