A Forty-Nine Day Evaluation of Bio-Mos® Replacement of Roxarsone in a Commerically Based Broiler Feeding Program
… on broiler production, gut morphology and bone strength. Three thousand and ten broilers were randomly assigned to 1 of 5 dietary corn-soybean meal based treatments: 1) negative control (NEG), basal diet; 2) positive control (POS; NEG + 27 ppm Bacitracin MD); 3) roxarsone (ROX; POS + 50 ppm …

The Impact Of Dietary Phytase Supplementation On Skeletal Biomechanics And Characteristics In Growing Swine And Mice
The misconception that bone is a static tissue underestimates its importance in human and animal health, as well as the many factors that influence its development and maintenance. Genetic, hormonal, mechanical and nutritional factors all influence bone strength and mass, particularly in early …

Effect of maternal dietary fats on growth rate and bone development of commercial broilers
… of maternal dietary fats on growth rate and bone development of commercial broilers was examined. Addition of fats [soybean oil (SBO), menhaden oil (MO) and chicken fat (CF)] to the maternal diet altered the tissue and yolk composition of the hens to reflect the dietary fat source. Day-old …

Alternate Housing for Laying Hens
… and foot health at the end of trial. Skeletal strength was determined by measuring the ultimate breaking force of tibiae and humeri. Statistical analysis was performed using the General Linear Model program of SAS (1989). Behavioral data were transformed using log transformation prior to the …

Effects of feeding diets varying in nutrient density to Hy-Line W-36 laying hens on production performance and profitability
… fat pad weights, but no effect was noted for bone ash or bone breaking strength due to increasing nutrient density. Significant linear responses due to nutrient density were seen for income, feed cost, and return over feed cost. In general, as nutrient density increased, egg income and feed …

Calcium Dynamics Affecting Egg Production, Skeletal Integrity, and Egg Coloration in Ring-necked Pheasants (Phasianus colchicus)
… pheasants store calcium in medullary bone before an experiment and can draw on this surplus during egg production, possibly skewing experimental results. We measured egg production, egg characteristics, and hen femur ash fraction in a 2-month experiment. Hens in the middle 5 dietary …
