Effect of Different Levels of Mineral and Vitamin Premix on Laying Hens Performance during the First Laying Phase

An experiment was conducted to evaluate the effects of different levels of mineral and vitamin premix on performance and egg traits of laying hens from 37 to 49 weeks of age. Two hundred and forty laying hens (Hy-Line W-36 strain) were randomly assigned to 5 dietary treatments of four replicates each with 12 hens per replicate). The levels of mineral and vitamin premixes in the experiment were ...

effect of dietary crude protein and methionine on egg production and egg quality of laying hens during phase ii

an experiment was conducted to evaluate the effect of dietary crude protein and methionine levels on quality and quantity of egg production. fifteen diets formulated with 3 levels of protein (13, 14 and 15%) and 5 levels of methionine (0.25, 0.28, 0.31, 0.34 and 0.37%) and fed to 420 birds in a 3×5 factorial arrangement. each diet was randomly fed to 4 replicates of 7 birds each and fed for 3 p...

Laying hens go undercover to improve production.

DURING 2007, all laying hen producers within the McDonald’s Restaurants UK supply base (McDonald’s Restaurants UK source eggs from free-range UK producers) were required to plant, if not present already, 5 per cent of the total range area in trees. Noble Foods supply free-range eggs into a variety of food retailers not all of which require tree cover on the range. In this study, the authors inv...
