| Abstract |
The present study was designed to estimate the effect of different sources of energy in broiler diets.The feeding experiments were conducted to replace yellow corn by other conventional energy sources such as date seeds, molasses and broken rice.The experiments were carried out at EI-Kanater -Khairia Poultry Research station and Poultry Nutrition Section, Animal Production Research Institute, Agricultural Research Centre, Ministry of Agriculture, Dokki.
In first experiment of date seeds, chicks had feeding
phase 1 (5, 10, 15% date seeds) during starter period and then feeding phase 2 (5, 5/10, 5/l5, 10, 10/15 and 15% date seeds) during finisher period.Adding 5 and 10% date seeds the diet (feeding phase 1) increased live weight significantly .Also differences in live body weight from (7-45 days of age) feeding phase 2, were highly significant.Feeding phase 2 (5/10,5 15,/ and 10/15% date seeds) recorded more improvement comparing with feeding phase 1 (5, l0.and 15%) Feed efficiency in starter period indicates no significance The better feed efficiency was evidenced in 5/10% date seeds (finisher period) mortality from 7-45 days of age were due to accidents. Results indicated no significant differences in weight of inedible parts among treatments.
Similar results were obtained for giblets and total edible meat. Analysis of variance of carcass revealed that differences were significant among groups results showed significant variation in serum total proteins, albumin globulin ratio, serum total lipids and serum cholesterol, but differences in globulin GPT and GOT were significant. However, these results are considered within the normal ranges.
In the second experiment, molasses supplementation showed no significance for body weight among groups 0, 5, 10 and 15% respectively from 7-28 days of age (feeding phase 1). Results at the end of the experiment (feeding phase 2) indicated that the body weight was significantly heavier in 5/10%.
Molasses increased feed intake during starter and finisher periods. Feed efficiency was improved by supplementing broiler diets with molasses (excluding 15%). Mortality data were not influenced by the diets. Data also clarify that the increase that the molasses level from 5% up to 15% had significant effect on inedible parts, similar results were obtained in total edible meat end carcass. Molasses levels had no significant effect on giblets weight. Results showed significant variations in serum total proteins, globulin serum, total lipids (mg/100 ml) serum cholesterol (mg/100 ml), and (GOT) among levels of molasses.
There were differences in live body weight by adding broken
rice in starter and finisher periods The best feed efficiency was in 10% level of broken rice Treatment showed no effect on mortality. Analysis of variance of inedible parts were significant, while they were significant in total edible meat, carcass and giblets. The addition of broken rice caused no significant differences in the serum total protein, albumin. Globulin, albumin/globulin ratio and GPT.But there were significant differences among treatments in cholesterol total lipid and GOT.
A comparison results of levels and sources of energy showed heaviest body weight were obtained in 15/10% date seeds, followed in descending order by those of 5/10% molasses, 30% broken rice and control group respectively. The best feed efficiency were found in level 5/l0% date seeds, followed by 10/15% molasses, control group and broken rice.Results revealed no significant differences among the best weight of carcass in date seeds, molasses, broken rice and control group. Similar results were in total edible meat and giblets.
The addition of date seeds to broiler diets increased the profit against the control and other sources of energy such as molasses and broken rice respectively.
The chemical composition of the tested materials indicated that date seeds, molasses and broken rice contain acceptable levels of (NFE) to be considered as sources of energy. The digestion coefficients nutrients showed that date seeds molasses and broken rice could be used for feeding poultry.
