REPLACEMENT EFFECT OF ROUGHAGE BY KITCHEN WASTE ON GROWTH PERFORMANCES OF RABBIT

Abstract

The present study was conducted to evaluate the replacement effect of roughage by kitchen waste on growth performance, sero-biochemical profile and nutrient digestibility of growing rabbit. There were three dietary treatment groups including 40 gram concentrate and adlibitum fodder, 40 gm concentrate and adlibitum road side grass and 40 gm concentrate and adlibitum kitchen waste of T1 T2 and T3, respectively. Forty five weaned crossbred New Zealand White growing rabbits (aged about 40 days) were distributed into three treatment groups in a completely randomize design for a period of 30 days. Weekly dry matter intake was not significantly influenced by feeding kitchen waste. The feed conversion ratio was not significantly differed among the treatment groups, where highest feed conversion ratio was found in 40 gm concentrate and adlibitum kitchen waste group. Final body weight, cumulative body and weekly body weight gain was not differed significantly in either of three dietary treatments. The nutrient digestibility of different proximate components differed significantly (p<0.05)among different treatment groups. The digestibility of dry matter and crude fiber, and availability of ash were found highest (63.45%, 56.47% and 63.53%, respectively) in T3 group (kitchen waste group). The digestibility of crude protein (63.53%), ether extract (56.78%) and nitrogen free extract (56.71%) were highest in T2 treatment group (Road side grass group). The serum biochemical parameters like- total protein, albumin, phosphorus, calcium, glucose, creatinine, urea and SGPT were varied significantly among the treatment groups but the value was within the normal limits. The study showed that kitchen waste might be efficiently used as a roughage replacer in broiler rabbit diet without affecting the performance of the animals.
