Expression studies suggest that the incidence and severity of tibial dyschondroplasia (TD) in chickens, Gallus gallus, may be affected by the aggrecan gene, AGC 1. Here, results are described of a scan for single nucleotide polymorphisms (SNP) in AGC

Nutrient equivalency of Natuphos Phytase for minerals, amino acids, and energy has been estimated elsewhere for broiler chickens. The current study was to evaluate equivalent values of 600 FTU/kg Natuphos Phytase for amino acids and energy in 3,150 b

Continued genetic selection for improved BW gain has met an obstacle of skeletal disorders in broiler chickens. Two broiler chicken lines (HTD and LTD) were developed by 10 generations of divergent selection for tibial dyschondroplasia (TD) incidence

Ability to utilize dietary phytate P was evaluated in 1,387 broiler chicks of 45 sire and 180 dam families, by feeding a corn-soybean base diet supplemented with no inorganic P and a low level of Ca. These chicks were the progeny of high and low inci

The effect of 25-hydroxycholecalciferol (25-OH-D3) on tibial dyschondroplasia (TD) incidence was evaluated by a factorial experiment of two broiler lines and three diets. Birds from lines with high (HTD) and a low (LTD) incidence of TD were fed three

Type × collagen is produced exclusively in hypertrophic chondrocytes of the growth plate of the proximal tibiotarsus and is believed to play an important role during normal development from chondrogenesis to osteogenesis. Chondrocytes of chickens wi

Lines selected for high (H) and low (L) incidence of tibial dyschondroplasia (TD) for eight generations and a randombred control (C) line of broiler chickens were fingerprinted by random amplification of genomic DNA mixed from 20 individuals of each

Relationships among the incidence of tibial dyschondroplasia (TD) with 7-wk live BW, carcass component weights (CCW), and abdominal fat weight (AFW) were assessed using high and low incidence of TD lines developed by a seven-generation divergent sele

This study considered the effect of dietary sodium zeolite A (SZA) on processing yields and tibia characteristics of male and female broilers divergently selected over three generations for high and low incidence of tibial dyschondroplasia (TD). Gene

Broiler breeder pullets were subjected to photostimulation (PS) at either 14, 17, or 20 wk of age after attaining greater than recommended BW during rearing in order to determine effects on age at onset of lay, egg weight, and egg production. During
