The bypass protein feeding study was carried out using twenty-four seven months old Khari goat kids at Sarasawati goat farm, Naubise, Dhading, from June to October, 2014. Goats were grouped randomly in three complete blocks (RCBD) and two goats from each of the block were allocated to each of four treatment. Before starting the experiment, goats were drenched against internal parasites with Fenbendazole@5mg/kg body weight. Four types of ration were formulated marked as T1: Foliage of Stylosanthes guianensis and Leucaena leucocephala (Ad libitum); T2: Foliage of Stylosanthes guianensis 34%, Leucaena leucocephala 33% and commercial concentrate feed 33% (DM basis); T3: Foliage of Stylosanthes guianensis 34%, Leucaena leucocephala 33%, HCHO treated maize meal and commercial concentrate feed 33% (DM basis) and T4: Foliage of Stylosanthes guianensis 34%, Leucaena leucocephala 33%, HCHO untreated maize meal and commercial concentrate feed 33% (DM basis). The average dry matter feed intake was highest for T1 (54.23 kg) followed by T2 (53.13 kg). Similarly, feed conversion efficiency was higher in T1 (4.42) followed by T4, T2 and T3 (3.91; 3.87 and 3.43 respectively). Protein conversion efficiency was not significantly influenced by different concentrate level in diets. The total body weight gain was highest in T2 (2.73 kg) with average daily gain of 27 g followed by T3 with total weight gain of 2.23 kg and daily gain of 22 g. Crude protein intake varies significantly with respect to treatment and highest value of 64 g/day was observed for T3 and lowest value of 57 g/day was observed for T1 treatment. Significant differences in nitrogen intake were observed between different experimental feeds. Rumen pH affects gaseous balances with lower NH3-N losses (12.86 mg/L) and CH4:CO2 (0.018:1) ratio was noted for T3. To get optimize rumen activities and enhancing bypass properties yielding higher benefits, it can be concluded that the supplementation of formaldehyde treated maize meal and concentrate mixture is beneficial for Khari goats in addition to ad libitum feeding of protein roughages like Stylosanthes guianensis and Leucaena leucocephala.
