Cost and Benefit Analysis of a Preconditioning Feeder Calf Program AgEcon
Donnell, Jeri; Ward, Clement E..
Objectives were twofold: Determine key factors influencing preconditioning cost and returns; and determine the premium for age and source verified, preconditioned calves sold at a public livestock market. Data provided by the Samuel Roberts Noble Foundation show preconditioning returns depend significantly on number of days preconditioned, average daily gain, and cost of vaccinations, hay, feed, and mineral. Noble Foundation cooperators received a premium for age and source verified, preconditioned feeder cattle when sold at market. Significant coefficients averaged across five sales conclude that Noble Foundation management practices receive a $2.49/cwt premium when compared to all other cattle sold at market.

Determinants of Price Differentials in Oklahoma Value-Added Feeder Cattle Auctions AgEcon
Williams, Galen S.; Raper, Kellie Curry; DeVuyst, Eric A.; Peel, Derrell S.; McKinney, Doug.
Many value-added practices cannot be observed by feeder cattle buyers. Third-party verification can decrease market inefficiency associated with this asymmetric information. We evaluate the effectiveness of a verification program, the Oklahoma Quality Beef Network, in increasing received prices. We estimate the value of verification, weaning, vaccinating, certification and phenotypic traits of feeder cattle at Oklahoma auctions. Results indicate that the OQBN program adds $2.39 to $5.74/cwt. Vaccinating calves adds $1.44/cwt, and weaning calves adds $2.05/cwt. Differential values for lot size, average weight, hide color, frame size, conditioning, Brahman influence, gender and other characteristics are also reported.

Determining the Variation in Certified Preconditioning Premiums for Heifers and Steer AgEcon
Schumacher, Stephanie; Peel, Derrell S..
This study applies separate hedonic models to Oklahoma Quality Beef Network data to determine differences in the value of preconditioning premiums for steers versus heifers. Results indicate that preconditioning values are generally lower for heifers but exceed steer premiums at higher weights. Separate treatment of steers and heifers is validated.

Market Valuation of Preconditioning Feeder Calves AgEcon
Avent, R. Keith; Ward, Clement E.; Lalman, David L..
Preconditioning calf programs, while not new, are becoming more prevalent. They provide benefits to cow-calf producers while adding value for feeder cattle buyers. However, questions remain regarding the economic costs and returns of such programs. A model was estimated with data from three consecutive-day sales, to determine the value that buyers place on preconditioning programs and related feeder cattle traits. Our results indicate that price premiums, although evident, appear to be insufficient by themselves to cover the marginal costs of preconditioning.

PRICE PREMIUMS FROM A CERTIFIED FEEDER CALF PRECONDITIONING PROGRAM AgEcon
Ward, Clement E.; Lalman, David L..
Preconditioning calf programs, while not new, are becoming more prevalent. They provide benefits to cow-calf producers while adding value for feeder cattle buyers. However, questions remain regarding the marginal returns from marketing preconditioned calves exceeds the marginal costs for preconditioning. This paper reports estimates from two models to determine the premium paid by feeder cattle buyers for preconditioned calves in the Oklahoma Quality Beef Network (OQBN) program. One model assumes feeder calf characteristics are independent as most previous research. The other assumes interdependency between several characteristics that are affected by preconditioning. Data were from seven feeder calf sales in Oklahoma in 2001 and another seven sales in...

Procedimento alternativo no teste de tetrazolio em sementes de soja. Repositório Alice
COSTA, N.P. da; FRANCA NETO, J. de B.; KRZYZANOWSKI, F.C.; HENNING, A.A.; OLIVEIRA, M.C.N. de.
O objetivo desse estudo foi desenvolver um procedimento alternativo para reducao do periodo de precondicionamento de sementes de soja no teste tetrazolio. Foram empregados dois tamanhos de sementes de doze cultivares de soja [Glycine max (L.)Merrill], produzidas em Londrina, PR em 1993 e 1994. Os tratamentos utilizados foram dois periodos de embebicao (quatro horas e seis horas) na temperatura de 41 C., tendo como testemunha o procedimento-padrao de dezesseis horas, a 25.C. Os parametros usados para avaliar os tratamentos foram o vigor [TZ (1-3)], a viabilidade [TZ(1-5)], a deterioracao por umidade [TZ(6-8)], o dano mecanico [TZ(6-8)], as lesoes por percevejos \{TZ(6-8)] e o teor de agua das sementes. O periodo de seis horas a 41.C. propiciou condicoes...

Relationships among alcoholic liver disease, antioxidants, and antioxidant enzymes OAK
Han, Kyu-Ho; Hashimoto, Naoto; Fukushima, Michihiro.
Excessive consumption of alcoholic beverages is a serious cause of liver disease worldwide. The meta-bolism of ethanol generates reactive oxygen species, which play a significant role in the deterioration of alcoholic liver disease (ALD). Antioxidant phytochemicals, such as polyphenols, regulate the expression of ALD-associated proteins and peptides, namely, catalase, superoxide dismutase, glutathione, glutathione peroxidase, and glutathione reductase. These plant antioxidants have electrophilic activity and may induce antioxidant enzymes via the Kelchlike ECH-associated protein 1-NF-E2-related factor-2 pathway and antioxidant responsive elements. Furthermore, these antioxidants are reported to alleviate cell injury caused by oxidants or inflammatory...
