Abstract

This study determined the effect of Neem Leaf Meal (NLM) based - diets on growth response, haematological and serum biochemical indices of female rabbits (does). Twenty four (24) weaned rabbits (5 - 6 weeks old with average body weight of 600 ±1.05g) were used. The NLM was included in the diets at 0, 5, 10, and 15% levels as treatments TI , T2, T3, and T4, respectively. The rabbits were divided into four groups of six (6) each and randomly assigned to experimental diets using a Completely Randomized Design (CRD). Water was provided ad libitum and the rabbits were housed in disinfected wooden hutches for 56 days. Data on growth response, haematological and serum biochemical indices were collected and analysed using analysis of variance (ANOVA). Results revealed that the growth performance parameters showed significant (P<0.05) differences between dietary treatments with progressive decrease in values as the levels of NLM inclusion increased across the diets. The final weight gain ranged between 860 and 970 g/rabbit. The total weight gain was between 310 and 380 g/rabbit, total feed intake ranged between 2150 and 2221 g/rabbit while FCR ranged between 5.84 and 6.94. Growth parameters beyond 10% inclusion level were least compared with values in the control diet. The haematological indices showed that all parameters were significantly (P<0.05) affected by dietary treatments and within the normal ranges for apparently healthy rabbits. The serum biochemical indices were within normal ranges but not significantly affected (P>0.05) by dietary treatments. The study concluded that 10% NLM can be included in the diets meant for rabbits without fear of compromising growth performance and blood characteristics.Key words: Neem, female rabbit, growth, blood indices

Highlights

Scarcity of feed resources has been the main limitation in the production of livestock products to meet the animal protein requirements of humans and other industrial needs
Source and processing of Neem Leaf Meal (NLM) Fresh neem leaves were harvested from neem trees within the University environment
The growth parameters decreased progressively in value as the NLM inclusion levels increased across the diets

Summary

Introduction

Scarcity of feed resources has been the main limitation in the production of livestock products to meet the animal protein requirements of humans and other industrial needs. To develop balanced and economical feeds to compliment and possibly replace the scarce supplies from the expensive conventional sources, there is the need to search for alternative and readily available cheaper feed stuffs that are not directly consumed by man. There is an urgent need for alternative locally and cheap sources of feed ingredients those that do not attract competition in consumption between humans and livestock or have no direct relevance in human food chain. One of such possible sources of cheap feed stuff is neem leaf meal
