Dietary interaction of 1,4-diaminobutane (putrescine) and calcium on eggshell quality and performance in laying hens.
An experiment was conducted to evaluate the potential dietary interaction between 1,4-diaminobutane (putrescine) and calcium on eggshell quality and overall laying performance. One hundred ninety-two 30-wk-old White Leghorn hens were fed a corn-and soybean-meal-based diet supplemented with 0.00, 0.05, 0.10, or 0.15% putrescine and 2.5, 3.0, 3.5, or 4.0% calcium in a factorial design (12 birds p...
متن کاملeggshell formation in Tsaiya ducks and Leghorn hens. DIETARY CALCIUM EFFECT ON CALCIUM AND MAGNESIUM CONTENT IN EGGSHELL
Tsaiya ducks and Leghorn hens are the two major laying birds raised in Taiwan. They are all excellent egg layers. Tsaiya ducks are small in body size (1.3 kg) with bigger egg weight (65 g) and stronger eggshell breaking strength than eggs from hens. The eggshell consists mainly of calcium carbonate, hence calcium plays an important role in the eggshell formation. Magnesium is also present in eg...
متن کاملEffects of Dietary Calcium Levels on Productive Performance, Eggshell Quality and Overall Calcium Status in Aged Laying Hens
This study was conducted to investigate the effects of diets with varying levels of calcium on egg production, shell quality and overall calcium status in aged laying hens. A total of five hundred 70-wk-old Hy-Line Brown layers were divided five groups and fed one of the five experimental diets with 3.5%, 3.8%, 4.1%, 4.4%, or 4.7% Ca, for 10 weeks. There were no significant differences in feed ...
متن کاملEffects of reducing dietary methionine, linoleic acid, choline and increasing energy on performance and eggshell quality in aged laying hens
An experiment was conducted to determine whether egg quality during the late stage of egg production can be improved by using diets that are effective in reducing egg size. The experiment was conducted in completely randomized design with six treatment groups and four replicates each with ten hens from 94 to 106 wk of age. Three 28-d periods used for different dietary factors including: 1) Cont...
متن کاملEffects of Dietary Corticosterone on Yolk Colors and Eggshell Quality in Laying Hens
The objective of this study was to investigate the effects of dietary corticosterone on egg quality. For 2 weeks hens received either control or experimental diet containing corticosterone at 30 mg/kg diet. Feed intake and egg production were monitored daily, and body weight measured weekly. Egg weights and egg quality were measured daily. Corticosterone treatment resulted in a remarkable incre...
