The Lajas Research and Development Center evaluated different methods of forced molting among medium weight, brown-egg-producing hens of the Hisex strain that had been laying 10 months. Second year production, efficiency of feed utilization, egg weight and initial and final body weights did not ...
Enhance the laying rate, reduce the persentage of pimpled eggs, soft shell eggs and shell-less eggs. After 40-week-old, prevent fatty liver syndrome and reduce mortality. RUNEON improve egg production performance and FCR Location: Shandong, China Animals: 23-week-old ISA Brown RUNEON improve...
High AT decreased egg production and composition traits: egg number, laying rate, clutch length, mean egg weight, and shell thickness were reduced significantly. At the same time, the days of pause and the proportion of cracked eggs were increased. Significant genotype × temperature interactions ...
Effect of Different Levels of Manganese and Zinc on Performance Traits and Breaking Eggs in Laying Hens This experiment was conducted to evaluate the effects of supplementing the diet of laying hens with a combination of Zn and Mn on performance traits and br... A Zamani,HR Rahmani,J Pourrez...

Our rod conveyor has an automatic cleaning function to ensure that soft shell eggs and waste are removed in time and not collected. The eggs can travel freely between the rows of cages, without causing congestion obstacles due to lateral collection. We have an advanced defecation ...
We still have two out of five hens laying, but it is molting season and we expect egg production to stop soon. That is why I freeze the abundance of eggs in the spring. I break open the eggs, beat them slightly with a pinch of salt and put four eggs per baggie into the freezer....
Older hens in production lay larger but fewer eggs than younger birds, and the incidence of soft and broken shells is greater in older hens than younger. These changes are attributable at least in part to changing hormone profiles and diminished ability of the hen to transport calcium at the ...
Laying Performance. Mortality was checked daily and dead birds were recorded to adjust estimates of egg laying rate and egg mass as appropriate. Number of total laid eggs, defective eggs (including those with double-yolk, soft-shell, cracked, very small malformed, etc.) and total egg weight ...
