Feeding Systems And Fresh Lamb Color Stability, Koushik Mondal

Theses and Dissertations--Animal and Food Sciences

Consumers consider the surface color of fresh lamb as the indicator of freshness and wholesomeness, which affects their purchase decisions. The redox chemistry of myoglobin (Mb) determines the color of fresh lamb. Artificial raising on milk replacer (a pre-weaning strategy) as well as red clover supplementation are management strategies used in lamb production. This thesis focuses on the effects of artificial raising on milk replacer and red clover supplementation on the color and oxidative stability of fresh lamb.

In the first experiment, the effect of pre-weaning with milk replacer on the carcass attributes, color stability and lipid oxidation of lamb …

Effects Of Post-Hatch Holding Time And Early Nutrition Strategies On Growth Performance, Carcass And Skeletal Characteristics Of Young Chickens, Marquisha A. Paul

Theses and Dissertations--Animal and Food Sciences

The study objectives of this thesis were to evaluate the effects of delayed feeding and specific aspects of the Programmed Nutrition (PN) feeding strategy (Alltech, Inc.) on growth performance, carcass characteristics, and skeletal characteristics of commercial broiler chicks through market age, as well as investigate the effects of breed and the PN feeding strategy on early growth and development. When commercial broiler chicks were fed reduced nutrient diets, delayed feeding decreased early growth performance and carcass yield (P<0.05), whereas post-hatch PN conditioning for 72 hours improved early growth performance and alleviated the negative effects of delayed feeding on carcass yield (P<0.05). Through market age, delayed feeding improved Gain: Feed (P<0.05), while PN had the opposite effect. Interactive effects and main effects of delayed feeding and PN were observed for tissue mineral concentration (P<0.05). PN lowered bone ash % (P<0.05) and increased meat oxidation of broiler chicks during storage (P<0.05). PN also had negative effects on early growth performance and bone breaking strength (P<0.05) of various meat-type breeds, but especially for non-commercial, moderate-growing or fast-growing breeds. In conclusion, PN may be suitable for commercial broiler chicks that experience delayed feeding and are fed reduced nutrient diets.

Effects Of Growth-Promoting Technologies On Feedlot Performance And Carcass Characteristics Of Crossbred Heifers, S. M. Ebarb, K. J. Phelps, J. E. Axman, C. L. Van Bibber, J. S. Drouillard, J. M. Gonzalez

Kansas Agricultural Experiment Station Research Reports

The use of growth-promoting technologies has become a common practice in the beef cattle industry as producers strive for efficient growth and greater lean deposition. Two common technologies include exogenous hormonal implants and beta-adrenergic agonists (β-AA). Combination implants containing estrogen and testosterone increase muscle mass by elevating protein synthesis and/or reducing protein degradation. The increase in protein synthesis allows the animal to produce more lean muscle tissue. Optaflexx (Elanco Animal Health, Greenfield, IN) is a popular β-AA that works as a repartitioning agent to redirect nutrients toward muscle deposition and away from adipose tissue production. The two technologies utilize separate …

Growth And Carcass Characteristics Of Three Fat-Tailed Pure Breeds Under Grazing With Concentrate Supplementation, Muhli̇s Maci̇t, Sirri Şahi̇n, Nuri̇ni̇sa Esenbuğa, Mevlüt Karaoğlu

Turkish Journal of Veterinary & Animal Sciences

Growth performance, carcass measurements and carcass characteristics of three fat-tailed Turkish breeds (Awassi = A, Morkaraman = M and Tushin = T) weaned at 2.5 months of age and subjected to semi-intensive feeding during a grazing period on pasture for 70 days were evaluated. At the end of the 70-day grazing period, M lambs showed the highest performance for daily weight gain and the amount of concentrate consumed per bodyweight gain in addition to grazing on pasture. The effects of the breed and sex of lambs on daily weight gain on pasture were significant (P < 0.05) and highly significant (P < 0.01), respectively. Male lambs were superior to female lambs with respect to daily weight gain on pasture. The slaughter traits, carcass measurements and carcass characteristics of 14 male lambs representing three fat-tailed breeds were compared at the end of the grazing period of the year in which they were born. After slaughter, carcasses were chilled at +4 °C for 24 h and measurements were taken on the intact cold carcasses. The carcasses were then dissected into wholesale cuts. The hot carcass weight and hindshank weight of M lambs were heavier than those of A and T lambs. M had a higher hot dressing percentage and larger M. longissimus dorsi (LD) area than those of A and T lambs. Most of the weights of wholesale cuts such as foreshank and breast, sirloin, leg, rib and hindshank were significantly (P < 0.05; P < 0.01) affected by sheep breed. It is recommended either that A, M or T male and female lambs weaned at 2.5 months of age in eastern Turkey should be fed with 450 g concentrate per head per day on pasture for 3 to 3.5 months of grazing season, or lambs should be supplemented with more than 450 g concentrate feed on pasture because native fat-tailed Turkish breeds supplemented with 450 g concentrate on pasture did not give carcasses with an adequate commercial weight at the end of a 70-day fattening period.
