Sprouted Soybeans, Mash and Grains for Emergency Feeding of White Leghorn Pullets

Early access to perches in caged White Leghorn pullets.

Osteoporosis, a progressive decrease in mineralized structural bone, causes 20 to 35% of all mortalities in caged White Leghorn hens. Previous research has focused on manipulating the egg laying environment to improve skeletal health, with little research on the pullet. The objective of the current study was to determine the effect of perch access on pullet health, bone mineralization, muscle d...

Effects of perch access and age on physiological measures of stress in caged White Leghorn pullets.

The neuroendocrine system controls animals' adaptability to their environments by releasing psychotropic compounds such as catecholamines [epinephrine (EP), norepinephrine (NE), and dopamine (DA)], corticosterone (CORT), and serotonin (5-hydroxytryptamine or 5-HT). Changes of these neuroendocrine compounds have been used as biomarkers of animals' stress responses associated with their well-bein...

Use of Sprouted Grains for Cattle and Sheep

Effect of genetic selection on growth parameters and tonic immobility in Leghorn pullets.

Four genetic stocks of Leghorn pullets were used to evaluate the effects of genetic selection on growth and fearfulness behavior. Three of the stocks were the Ottawa randombred control stocks from 1950 (CS5), 1959 (CS7), and 1972 (CS10). The fourth stock was a 1993 commercial laying stock (CCS) whose ancestors were involved in the formation of the randombred control stocks. Pullets were reared ...

Effects of Chitosan and Whole Raw Soybeans on Feeding Behavior and Heat Losses of Jersey Heifers

This study aimed to determine the effects of chitosan, whole raw soybeans or their interaction on feeding behavior and heat losses through thermography assay of Jersey heifers fed high concentrate diets. Twelve Jersey heifers (age of 6±0.5 months and 139.50±25.56 kg of live weight, mean±SD) were randomly assigned to a replicated latin square design with 2 × 2 factorial treatment arrangement. Th...
