Effect of substituting concentrate feed with cassava (Manihot esculenta) silage on the performance of Tenyi Vo pig

The research was carried out on 20 weaned Tenyi Vo piglets of 2 months old, which were divided into four different treatment groups i.e. T1, T2, T3 and T4. The treatment groups T1,T2, T3 and T4 were fed with 20 % cassava silage + 80 % concentrated feed(T1), 15 % cassava silage + 85 % concentrate feed (T2), 10 % cassava silage + 90 % concentrated feed (T3) and only 100 %concentrated feed in T4 (control). Analysis of variance showed higher (P<0.05) final body weight in T1 with 7.43 kg followed by T2, T3 and T4. Higher weight gain of 0.64 kg/pig/week and significant difference (P<0.05) with T2, T3 and T4 that was 0.53kg, 0.49kg and0.45 kg, respectively. In the final week of the experimental study period, the average feed intake of T1 treatment group shows higher feed intake with 1.87 kg/pig/week followed by T2, T3 and T4. The overall average feed conversion efficiency of T1 at the final week shows better FCE as compared to T2, T3 and T4. 10 % morbidity and 10 % mortality was record during the whole experimental study period. Net profit per piglet and net profit per kg live weight showed better return value in T1 as compared to the other treatment groups followed by T2, T3 and T4, respectively. The overall performance in body weight, gain in body weight, feed intake, feed conversion efficiency and economics of production was better in T1 (BCR 1.21) as compared to the other treatment groups. Therefore, substitution of 20 % cassava silage into the diet of the Tenyi Vo pigs can be recommended for the farmers of Nagaland.
