Abstract


In order to evaluate the effect of taro tuber silage with natural yogurt on the productive performance of commercial pigs, a total of 60 castrated male pigs from the commercial hybrid Pietrain x Duroc x Landrace, of 70d of age, with initial average live weight of 25.45 ± 0.69 kg were used. The animals were distributed at a rate of 30 pigs in two treatments: T1 control diet (maize and soybean), T2 (substitution of 100 % of maize by taro tubers silage in the diet) according to a completely randomized design. The mean comparison was performed with the Fisher test(P≤0.05). There was no significant differences (P >0.05) for live weight (kg) at 4d (T1: 60.94; T2: 60.96) and 84 days (T1: 101.47; T2: 101.63), food intake (kg d-1) at 42 (T1: 2.19; T2: 2.19) and 84 days (T1: 2.79; T2: 2.79), weight gain (kg pig-1 d-1) at 42 (T1: 0.84; T2: 0.85) and 84 days (T1: 0.96; T2: 0.97) and feed convertion (kg kg-1) at 42 (T1: 2.60; T2: 2.60) and 84 days (T1: 2.90; T2: 2.89). In the feeding of commercial fattening pigs, it is possible to completely replace the maize by taro tubers silage with natural yogurt without affecting the animals productive performance.
Key words: fattening pigs, taro tubers yogurt, productive indexes.
