Climatic adaptation of laying hens [PDF]

Tropical Animal Health and Production, 1994
Three hundred Warren Isabrown female day old chicks were raised for 18 weeks in 3 distinct artificial climates described as temperate (20 degrees C, 60% RH), hot dry (32 degrees C, 40% RH) and hot humid (32 degrees C, 90% RH). At 18 weeks each group was divided into 3 and re-allocated to 3 similar air-conditioned laying rooms as during the growing ...

Fluoride tolerance of laying hens

British Poultry Science, 1997
1. One thousand Silver Grey Hyline hens were given drinking water containing 5 concentrations of added sodium fluoride (0, 6, 10, 14 and 20 mg/l) over a 17-week growth and 57-week laying period. The natural fluoride content of the water was 0.21 mg/l during the growing period and 0.29 mg/l throughout lay. 2. During the rearing phase, efficiency of food

The effects of lindane on laying hens

British Poultry Science, 1972
Synopsis Feeding lindane, in capsule form, to laying hens at a rate equivalent to 100 mg/kg food for 1 or 2 weeks had little effect on egg production. Longer periods of feeding resulted in a 20 to 30% decrease in the rate of egg production. When treatment was stopped after 4 weeks, the birds recovered and egg production returned to its original rate ...
