Physiologic values of broiler femurs at different growth phases using Bone densitometry and Bone Breaking Strength
(2011-12-01)
The objective of this experiment was to determine the normal values of Bone Radiographic Density (BRD) by using the optical densitometry in radiographic images and the Bone Breaking Strength (BBS) of broiler femurs at ...

Influence of early quantitative food restriction on long bone growth at different environmental temperatures in broiler chickens
(Carfax Publishing, 2000-09-01)
1. This investigation was carried out to study the influence of early quantitative food restriction (40% of ad libitum intake from 7 to 14 d of age) and environmental rearing temperature (thermoneutral, cold and hot) on ...

In ovo feeding with 25-hydroxycholecalciferol influences bone mineral density of chicks
(Sociedade Brasileira de Zootecnia, 2021-06-21)
The purpose of this study was to determine if in ovo feeding with 25(OH)D3 could influence the incubation parameters of bone mineral composition, mineral density, and bone breaking strength in post-hatch broilers. Fertile ...
Phenotypic, genetic and environmental parameters for traits related to femur bone integrity and body weight at 42 days of age in a broiler population
(Poultry Science Association Inc., 2015-11-01)
Intense selection among broilers, especially for performance and carcass traits, currently favors locomotion problems and bone resistance. Conducting studies relating to development and growth of bone tissue in broilers ...
Effects of neonatal castration and androgenization on sexual dimorphism in bone, leptin and corticosterone secretion
(ELSEVIER SCIENCE INCNEW YORK, 2012)
This study investigated the role of neonatal sex steroids in rats on sexual dimorphism in bone, as well as on leptin and corticosterone concentrations throughout the lifespan. Castration of males and androgenization of ...
Neither altered incubation temperature during fetal development nor preferred rearing temperature improves leg bone characteristics of broilers
(2020-10-01)
The present study evaluated whether broiler femoral and tibiotarsal characteristics (as assessed at slaughter age) could be improved if birds were reared under their preferred temperature and whether continuous high or low ...
