| dc.description | Poultry is one of the most important sectors of livestock that provides cheapest
animal protein (nutritious egg and meat) for human consumption within shortest
period of time. Poultry production has greatly flourished during last three
decades in Bangladesh. However, the acute dearth of fluctuating feed supply
and their price are the major constraints to poultry production in developing
countries like Bangladesh. By the year 2020, world population would be lifted
to 8 billions with most of the population growth coming from the developing
countries (Singh ef al., 2001).With increasing demand for livestock products as
a result of rapid growth of population in the world economies and shrinking
land area, future hopes of feeding the millions and safeguarding their food
security will depend on better utilization of unconventional feed resources that
do not compete with food for human beings. Poultry feed ingredients animal
protein sources in particular, are very expensive and scarce due to high
competition among poultry, human and other animals resulting in the escalating
cost of these ingredients. The feed cost usually constitutes the major proportion
which ranges between 60-75% of the total cost of poultry production and
protein cost account for over 15% of the total feed cost in livestock and poultry
farming (Ojewola et al., 2005). The prices of conventional protein source feed
ingredients such as groundnut cake; fish meal and soybean meal are always high
and cannot permit profit maximization in poultry ventures. In view of this,
current research interest in the poultry industry is aimed at finding alternatives
to those elusive feed ingredients. | en_US |
| dc.description.abstract | The objective of this study was to determine the effects of various dietary levels
of mulberry (Morus alba) leaf meal on production performance, egg qualities
and egg yolk cholesterol. The study was conducted at the poultry farm and Dairy
and poultry science laboratory, Hajee Mohammad Danesh Science and
Technology University (HSTU), Dinajpur district. In this study, Forty-eight 30-
wk-old laying hens (Hi-sex brown) were divided into 4 dietary groups each with
4 replications (3birds/replication) and offered manually prepared diets
supplemented with 0, 3, 6 and 9% mulberry leaf meal for 8 weeks. Eggs were
collected and weighted daily. Laying performance, egg quality and feed
conversion ratio were evaluated. Results showed that the feed intake, egg
production, egg weight, egg mass, feed conversion ratio, body weight and egg
qualities were insignificant among the treatment groups. However, the egg yolk
cholesterol concentration was significantly decreased (P<0.05) with higher
levels of mulberry leaf supplementary diets. Egg yolk cholesterol was decreased
at 9.4, 12.5 and 14.8% with 3, 6 and 9% level of mulberry leaf meal
supplementation, respectively. Based on the results, it could be concluded that
the supplementation of mulberry leaf meal up to my investigation level (9%) has
potentiality in reduction of egg yolk cholesterol. | en_US |
