High density lipoprotein cholesteral. If you have any questions, please click on the button below to access our contact page. Lysine ratio on egg production parameters and egg yield in Hy-Line W hens.
There is no explanation for the concurrent increase in egg weight and shell thickness for hens fed the high nutrient density diets, under the conditions of this study.

Then, they were allowed to equilibrate in moisture with atmospheric air before being weighed, finely ground and stored in plastic bags until analysis. One replicate group per treatment was fed its respective experimental diet for a three-day test period.
The aim of the present study was to evaluate the productive performance of laying hens fed high-nutrient-density diets during the second phase of egg production cycle, under Egyptian summer conditions. The Bovans layer is robust and balanced. Egg components and some egg quality parameters of laying hens fed high-nutrient-density diets, examined at 50 weeks of age. World Egg Day Along with our high performing products, we deliver technical support for you and your operations.
Nutrient digestibility of the experimental diets: Bovans White More information. The Bovans Brown has excellent feed intake capacity and robustness so that it fully expresses genetic potential in multi-age and free range environments. Four high nutrient density diets were also compounded to contain So, the reduced feed intake of hens fed the HND4 diet might be attributed to the increased nutrient density of the diet rather than to the effect of heat stress per se.
In addition, Novak et al. Blood parameters of laying hens: Comparative study for different levels of energy and protein in local duck breeds rations during laying period. Egg quality measurements of laying hens: Asian Journal of Animal and Veterinary Advances, The statistical processing of data was performed via one-way analysis of variance using the Statistical Analysis System SAS.

The calculated analysis of the control diet as fed basis was as follows: Dietary fat supplementation at high temperature is well known to decrease heat increment of the feed and can improve the voluntary feed intake of heat-stressed birds Daghir, The high similarity in DFI of hens fed the control, HND1, HND2 whihe HND3 diets is an indication that the ambient temperatures, prevailed under the conditions of this study, were not too severe to adversely affect feed intake of hens.
Bovans Brown More information. The observed insignificant differences in most blood parameters of Bovans White laying hensexamined herein, in response to feeding the high-nutrient-density diets agree with the results of Rabie et al. Multiple range and multiple F tests. The Bovans White is a well-balanced bird with strong livability, excellent laying persistency, and feed efficiency.
Level of plasma globulin was calculated by subtracting level of plasma albumin from that of total protein. In contrast to the present results, Jalal et al.

Effect of bird cage space and dietary metabolizable energy level on production parameters in laying hens. In this respect, Kamar et al. Working with Japanese quail, Rabie et al. Each whote kg of premix contained: Nutrient digestibility of the experimental diets for 55 weeks old whits hens fed diets containing high nutrient densities. Two hundred hens were randomly assigned to five equal dietary treatments, five replications each. Measurements in the field are the foundations of our genetic progress.
Composition and chemical analyses of these experimental diets are illustrated in Table 1. Productive performance of laying hens: In addition, Zhang and Kim investigated the effects of feeding two dietary energy levels vs. How to cite this article:
