Performance of grower pigs raised on kitchen waste based ration supplemented with protein sources

A kitchen waste based system of feeding trial was conducted for a period of 90 days to elucidate the performance of grower pigs in terms of body weight gain as well as cost of production. Twenty four White Yorkshire grower piglets (2.5 months of age and 12 kg body weight) were divided into three equal groups viz Control (supplied with standard concentrate mixture for grower pigs as per BIS 1986), T₁ (supplied with ration having 75% kitchen waste 10% mustard oil cakes, 10% guar korma and 5% mineral. Vitamin, amino acid premixes) and T₂ (supplied with only kitchen waste). The study reveled that kitchen waste contained higher DE in terms of 3300 Kcal/kg than the standard concentrate mixture 3000 kcal/kg. Significantly higher (p<0.05) body weight gain as well as average daily gain in body weight (402.22 ± 0.85) g was recorded in T₁ group in comparison to T₂ group (270.55 ± 1.45) g, which is approximately similar with Control group (400.77 ± 1.23) g. The feed conversion efficiency (kg feed/kg gain in body weight) was also significantly (p<0.05) better in T₁ group (3.25) in comparison to T₂ group (5.70), but almost similar with Control group (3.38). Cost of feed per kg gain in body weight was also lowest in T₁ group (Rs 31.00), followed by T₂ group (Rs 35.68) and highest in Control group (Rs 51.93). The best performance of the animals was observed in T₁ group fed kitchen waste in combination with protein, minerals, vitamins and amino acid supplements.
