Effect of feeding Asystasia gangetica weed on intake, nutrient utilization, and gain in Kacang goat

A high concentration of nitrate and total nitrogen (N) in Chinese violet (CV) weed (Asystasia gangetica) has a potential benefit as a digestible protein source for ruminant production in humid tropical regions. We conducted a study using twelve Kacang goats in a crossover design to investigate the effect of CV weed on intake, nutrient utilization, and growth. Four dietary treatments were tested: Guinea grass (Panicum maximum) ad libitum (GG), GG ad libitum and CV (1% live weight, LW) (GG + CV), CV ad libitum (CV), and CV ad libitum plus cassava chip (1% LW) (CV + CC) (dry matter, DM basis). No sign of nitrite toxicity was observed when the goat fed CV diet while intake, N retention, and LW gain was higher than goats on the GG and GG + CV diets (P
