Abstract

To investigate the effect of dietary mulberry leaf meal on body weight, feed conversion efficiency and blood cholesterol level, 240 day-old broiler chicks (Cobb 500) were divided into 6 treatments, each with 4 replications (10 birds/ per replicate) and offered manually prepared diets supplemented with 2.5, 3.5, 4.5% mulberry leaf meal (MLM), MLM Extract and 0.5% for a period of six weeks. Average body weight (g) gain increased (P> 0.05) at 2.5 or 4.5% supplementation of MLM and with MLM extract compared to control and antibiotic group. Feed conversion ratio was better at 4.5% supplementation (1.67) and on addition of MLM extract (1.63) compare to control (1.79). Total cholesterol, HDLcholesterol and triglyceride of broiler chicks in different dietary treatments of during experimental periods were non-significant at day 10 to 15 but total cholesterol and triglyceride decreased significantly (P>0.05) at d 15 to 22 compared to control and antibiotic group. Significant (P<0.05) reduction of total cholesterol and triglyceride with supplementation of mulberry leaf meal at 2.5, 3.5, 4.5% MLM, MLM extract were also observed at d 22 to 42 compared to control and antibiotic group. The result suggests that inclusion of mulberry leaf meal (both 3.5% powder and extract) may be used to formulate low-cost broiler grower diet in order to produce low-cholesterol broiler meat.

Highlights

The cost of feed constitutes is the major proportion between 60-75% of the total cost of poultry production and protein cost account for over 40% of the total feed cost in livestock and poultry farming (Ojewola et al, 2005)
The results shows that average body weight gain did not increased significantly while supplemented with different doses of mulberry leaf meal (MLM) and antibiotic diets
Average body weight gain increased more than 15% in MLM supplemented diets compared to control (To) and antibiotic fed group (T5)

Summary

Introduction

The cost of feed constitutes is the major proportion between 60-75% of the total cost of poultry production and protein cost account for over 40% of the total feed cost in livestock and poultry farming (Ojewola et al, 2005). The list of possible feed alternatives includes tree fodder mulberry leaves (Morus alba) as a source of dietary protein for commercial livestock and poultry operations. Mulberry grows well in the tropics and subtropics, and is reported to have excellent nutritional value as forage. It is grown extensively for its leaves, which are used for raising silkworms in the sericulture industry. Mulberry leaves are rich in protein (15-35%), minerals (2.424.71% Ca, 0.23-0.97% P) and metabolizable energy (1,130-2,240 kcal kg-1) with absence of or negligible anti-nutritional factors (Omar et al, 1999; Sarita et al, 2006). There is a need to study the effect of mulberry leaves inclusion in poultry diets on production performance, cholesterol and triglyceride in blood, meat and egg
