Effect of feeding guava (Psidium guajava) fruit waste on nutrient utilization in crossbred grower pigs

The study was undertaken to evaluate the effect of supplementation of guava (Psidium guajava) fruit waste (GFW) on nutrient utilization in crossbred (Hampshire x Ghungroo) grower pigs. Eighteen grower pigs (weighing 11.4–11.6 kg) of either sex were divided into three groups of six each in randomized block design. The experimental pigs were fed with diets namely standard grower ration (SGR) supplemented with 0% GFW, 5% GFW and 10% GFW, respectively, by replacing maize grain in T_v T₂ and T₃ groups. The average dry matter intake, digestibility co-efficients (%) of nutrients were increased (P<0.01; P<0.05) with increased level of GFW in experimental diet. Nitrogen balance (g/d) was found positive across all groups. The study, concluded that guava fruit waste can be supplemented at 10 percent level in grower crossbred pigs for better nutrient utilization and also to reduce the feed cost.
