this experiment was conducted to investigate the effects of various levels of cichorium intybus andcopper on performance and egg yolk cholesterol. total of 324 layer hens (hy-line w-36) were used in arandomized complete blocks with nine treatments, three replications of 12 birds in each from 38 to 50weeks of age. experimental diets include control, four levels of copper (150, 200, 250 and 300 m...

Double-yolked (DY) and single-yolked (SY) duck eggs (n = 1318 for both) were candled and weighed on Days (d) 2, 8, 12, 15, 19, 22 and 25 of incubation and yolk/embryo position was recorded on d2, d8 and at post-mortem. From d8 only eggs with live fertile yolk(s) remained in the incubator. On d2, 99.39% of yolks in DY eggs were in the adjacent position and by d8 yolk positions changed to paralle...

s of papers 9 The objective of this experiment was to determine differences between 10 breed crosses with regards to eggshell properties and embryo metabolism. Eggs from the flocks (51 to 54 weeks of age) were incubated in a single machine, moisture loss measurements were recorded. Additionally, embryo weight with out yolk (EMB) and residual yolk weight (YLK) were determined at 15, 18 and 21 d....

Athens Canadian Random Bred (ACRB) chickens, a 1955 meat-type control strain, were incubated with the 2013 Cobb 500 broiler to determine differences in egg composition, conductance values, incubation duration, hatch performance, and yolk utilization. Unincubated ACRB eggs had greater percentage solids than Cobb 500 eggs. The ACRB eggs had a greater solid portion as yolk, whereas the Cobb 500 de...

The aim of this research was to evaluate the changes in the Gelato ice cream properties at different levels of sweet whey protein concentrate (WPC) substitutions of egg yolk. Samples were made with two levels of egg yolk (4.5 and 9%). For each level one control sample with no WPC addition and four levels of WPC substitutions (20, 50, 80 and 100%) were made. Three replications of each treatment ...

This study was conducted to examine if L-carnitine supplementation in the Tris-egg-yolk extender can improve the motility characteristics, membrane integrity, and in vitro fertilization potential after cryopreservation of ejaculated bovine spermatozoa. It was carried out on January to May 2013 at the University of Wisconsin-Madison. L-carnitine at final concentrations of 0.5, 1, 10, and 30mM we...

experiment was conducted to evaluate the effect of different levels of egg yolk for coating and storing spermatozoa. ejaculates were collected from four rams. in each session, second ejaculates (n=4) were collected in a tube containing 1 ml coating buffers which were prepared by 10, 15 or 20% egg yolk plus tris-fructose. samples were pooled, centrifuged and the supernatant removed in the labora...

It has been shown by a comparison of the relative vapor pressures of egg yolk and egg white before and after the addition of sodium chloride to the white that the osmotic pressure of the yolk is greater than that of the white.

Objective: In this study, the effect of diet food (soybeans, egg yolk and chicken manure) on biomass weight and body composition (the amount of protein, fat, moisture and ash) Chironomid larvae were examined. Methods: For this purpose, 2.5 grams of food per Coconut considered in the period, with three replicates and Chironomid larvae during the period of 15 days in plastic pans were kept in nut...
