Abstract

CARRYING CAPACITY OF DRY MATTER, CRUDE PROTEIN AND TOTAL NUTRIENT DIGESTIBILITY OF CROP WASTE AS RUMINANT FEED IN TALAWAAN SUB-DISTRICT OF NORTHERN MINAHASA. A research evaluating nutrient carrying capacity of crop residues as ruminant feed had been conducted since 1^st March – 6^th April 2017 in District Talawaan North Minahasa  Regency. Descriptive method of analysis was used. Secondary data were collected from Balai Pertanian Peternakan dan Perikanan dan Kehutanan in Talawaan district and Statistics Center Bureau (BPS) North Minahasa Regency. Parameters observed were crop residues carrying capacity  and carrying capacity index of dry matter (DM), crude protein (CP) and total digestible nutrient (TDN). The results showed that carrying capacity of DM, CP and TDN were 9664 AU, 5240 AU and 8090 AU, respectively. Carrying capacity indexes were at safe levels (> 2) 13.09, 7.10, and 10.96 for DM, CP and TDN, respectively. It can be concluded that carrying capacity of DM (9664 AU), CP (5240 AU) and TDN (8090 AU) can provide nutrients for additional 8926 AU (DM), 4502 AU (CP) and 7351 AU (TDN) of ruminants in Talawaan District, North Minahasa Regency with carrying capacity index of >2.

Keywords: Food crop residues, nutrient carrying capacity, carrying capacity index, ruminant livestocks.
