Mulberry grows well in thetropics and subtropics, and is reported to have excellent nutritional value as forage. Itis grown extensively for its leaves, which are used for raising silkworms in thesericulture industry. Mulberry leaves are rich in protein (15-35%), minerals (2.42-4.71% Ca, 0.23-0.97% P) and metabolizable energy (1,130-2,240 kcal kg-1) withabsence of or negligible anti-nutritional factors. Mulberry leaves contain β-carotene, which can be converted with varyingefficiency by animals to vitamin A and the xanthophylls, which can be a good sourceof the pigmentation of egg yolk. Excellent results have beenobtained with using mulberry leaves as ruminant feed (Rojas and Benavides, 1994;Gonzalez et al., 1996; Omar et al., 1999). Information on feeding mulberry to non-ruminants is scanty but it has been used in pigs (Trigueros and Villalta, 1997), layinghens (Narayana and Setty, 1977), and rabbits (Deshmukh et al., 1993). Dot et al.(2000) demonstrated that the intake of mulberry leaves reduced the concentration ofserum lipids and atheromatous thickening of arterial intima in hypercholesterolemicrabbits. Although much work has been done on the utilization of rats, mice andrabbits, reports on the use of mulberry leaves in poultry feeds are limited. Thus thereis a need to study the effect of mulberry leaves inclusion in poultry diets onproduction performance, cholesterol and triglyceride in blood, meat and egg.Antibiotics as feed additives have been used for years.
