Evaluation Of Betaine And Methionine Replacement For Improving Performance And Meat Quality For Broilers Reared Under Higher Temperature Conditions, Malea Graham Frank
Evaluation Of Betaine And Methionine Replacement For Improving Performance And Meat Quality For Broilers Reared Under Higher Temperature Conditions, Malea Graham Frank
Graduate Theses and Dissertations
4,096 broiler chicks were randomly allocated to 128 floor pens (32 birds/pen). 2,048 day-old male broilers were placed in the east end of a barn, and the following week 2,048 day-old male broilers were placed in the west end. At each placement day, half of the chicks were Cobb 500 and half were Ross 708, and each pen contained only one breed source. East end birds received coccidiostat in the feed, west end received coccidial vaccine, and each end was under separate environmental control. Eight diets contained two levels of coccidiostat (0, 1 lb./ton), methionine (deficient, adequate), and betaine (0, …
Evaluation Of Low-Tannin Grain Sorghum In Broiler Chicken Diets, Samantha Aniecia Shelton
Evaluation Of Low-Tannin Grain Sorghum In Broiler Chicken Diets, Samantha Aniecia Shelton
Graduate Theses and Dissertations
Research trials were conducted to evaluate the effects of different levels of dietary grain sorghum on broiler live performance, carcass yield and shank (leg) and breast skin coloring. Iso-caloric diets were formulated where sorghum replaced corn at rates of 0% (control), 20, 40, 60, 80 and 100% for a total of 6 diets. For each of the two trials, 1500 Cobb 500 male broiler chicks were randomly allocated to 60 pens with 25 birds per pen (10 pens/diet) and grown to 46 days for the first research trial and 41 days for the second. There were no differences (P>.05) …
Evaluation Of Phytate And Phytase Interactions And Phytase Phase-Feeding On Bird Performance, Bone Characteristics And Meat Quality In Young Growing Broilers, Chance L. Williams
Evaluation Of Phytate And Phytase Interactions And Phytase Phase-Feeding On Bird Performance, Bone Characteristics And Meat Quality In Young Growing Broilers, Chance L. Williams
Graduate Theses and Dissertations
Two trials were performed using one-day-old male Cobb x Cobb 500 broilers to determine how dietary phytate and phytase levels as well as phytase phase feeding impacted bird performance parameters, tibia characteristics, and malonaldehyde (MDA) content of the liver, breast and thigh tissues. The first experiment consisted of 1,008 birds randomly placed in 48 floor pens within two commercial broiler houses at the Applied Broiler Research Farm (ABRF; 21 birds per pen; 0.76 ft2 per bird). A 2 X 3 factorial design was used with two levels of dietary phytate (0.21 and 0.31 %) and three levels of phytase supplementation …
The Human/Animal Interface: Emergence And Resurgence Of Zoonotic Infectious Diseases, Michael Greger
The Human/Animal Interface: Emergence And Resurgence Of Zoonotic Infectious Diseases, Michael Greger
Michael Greger, MD, FACLM
Emerging infectious diseases, most of which are considered zoonotic in origin, continue to exact a significant toll on society. The origins of major human infectious diseases are reviewed and the factors underlying disease emergence explored. Anthropogenic changes, largely in land use and agriculture, are implicated in the apparent increased frequency of emergence and reemergence of zoonoses in recent decades. Special emphasis is placed on the pathogen with likely the greatest zoonotic potential, influenzavirus A.
