Effect of feeding pineapple waste with probiotic supplementation on the performance of growing pigs PIGS

Abstract

A 5 month feeding trial was conducted on 24 weaned cross bred piglets (Hampshire newline× Local) pigs (11.53±1.08 to 11.75±1.03 kg body weight) to investigate the effect of newlinefeeding pineapple waste with probiotic supplementation on the growth performance, feed newlineconversion ratio, nutrient utilization, blood biochemical, faecal microbial count, carcass newlinecharacteristics and cost of feeding. Basal rations (BIS, 2001) were assigned as C, T1, T2 and newlineT3. The pineapple waste were sundried, chaffed into small pieces and then mixed with the newlinebasal diet at 10, 20 and 30% level for T1, T2 and T3 respectively. Probiotic (lactobacillus) newlinewas added at the level of 0.35g in all the ration including control. Two digestion trials were newlinecarried out once in the growing phase (18th week) and another one in the finishing phase newline(22nd week). Faeces and blood samples were collected from each treatment group at three newlinestages i.e., initial, grower and finisher stages of the feeding trial for estimation of total newlinebacterial count and for evaluation of haemato-biochemical parameters. For carcass newlinecharacteristics study, three pigs from each treatment were sacrificed at the end of the newlinefeeding trial. Study revealed improvement in feed consumption in the growing and finishing newlinephase and also found that T2 was significantly higher (Plt0.05). Apparent digestibility coefficient newlineof all the nutrients was comparatively higher in T2 followed by C, T1 and T3. newlineSignificant difference was found among the groups (Plt0.05) in apparent digestibility coefficient newlineof CP, EE and NFE in grower phase; whereas in finisher stage significant newlinedifference (Plt0.05) was observed in apparent digestibility co-efficient of DM, CP, EE, NFE newlineand OM among the groups. The average daily body weight gain (ADG) was significantly newlinehigher in T2 groups and resulted significantly higher total gain and final body weights than newlineC, T1 and T3. Significant difference was found in both phases among treatment group on newlinenitrogen balance where T2 was found significantly different from C, T1 and T3 (Plt0.05), newlinewhereas C
