In this work, the effect of finishing diet (pasture- or mixed-diet) on lipid and protein oxidation in beef homogenates was evaluated. Oxidation was chemically induced by ferrous iron and hydrogen peroxide. Lipid and protein oxidation were respectively measured by determining TBA reactive substances (TBA-RS) and protein carbonyl groups (DNPH coupling method). Evaluation of the antioxidant status...

Materials and methods: In Trial One (2272 pigs), litters were weaned at 12, 15, 18, and 21 days of age. In Trial Two (3456 pigs), litters were weaned at 15, 16, 18, 19, 21, and 22 days of age and categorized into three treatments (15.5, 18.5, and 21.5 days of age). In Trial Two, pigs in each age group were fed one of two nursery feeding programs. Each trial was conducted as a randomized complet...

T HE reliance on certain cereal grains as sole sources of dietary protein for finishing swine has been successful when supplemental lysine has been provided. Milo and wheat, appropriately supplemented with vitamins, minerals and lysine, have each produced gain and feed/gain equal to that of a 12 % protein cornsoybean meal diet (Jensen, Becker and Harmon, 1965, 1967). Recent introduction of Opaq...

The pork industry is constantly seeking economical methods which will increase production efficiency and carcass quality. Three nutritional management “tools” at pork producer’s disposal that have been demonstrated to improve growth performance and carcass characteristics are: 1) adding rendered animal fats to diets; 2) adding the recently approved feed additive ractopamine to finishing diets; ...

The Merit Partnership is a joint venture between U.S. Environmental Protection Agency (EPA) Region 9, state and local regulatory agencies, private sector industries, and community representatives. The partnership was created to promote pollution prevention (P2), identify P2 technology needs, and accelerate P2 technology transfer within various industries in southern California. One of these ind...

Thanks to high-throughput sequencing technologies, genome sequencing has become a common component in nearly all aspects of viral research; thus, we are experiencing an explosion in both the number of available genome sequences and the number of institutions producing such data. However, there are currently no common standards used to convey the quality, and therefore utility, of these various ...

Angus steers (n = 96; 321 ± 29 kg BW) were used to determine how previous exposure to increased dietary S would affect ruminal hydrogen sulfide concentrations ([H(2)S]) in the feedlot, to investigate the effects of dietary S on ruminal [H(2)S] during transition and finishing, and to determine if dietary S affects the glutathione status of finishing cattle. Steers were strip-grazed on smooth bro...

OBJECTIVE Multifetal pregnancy reduction (MPR) is a technique developed to reduce the risks of a multifetal pregnancy. The objective of this article was to report the outcome of MPR in the largest single-center experience to date. STUDY DESIGN A computerized database was used to determine the outcome of 1000 consecutive cases patients undergoing transabdominal MPR between the years 1986 and 1...

OBJECTIVE This study was conducted to compare growth performance, blood components and carcass traits by two feeding systems (concentrate with roughage separately [CON] vs total mixed ration [TMR]) in Hanwoo steers, and to learn the relationship between blood components during fattening or finishing phases and carcass traits in Hanwoo steers. METHODS Sixty steers aged 8 months were allotted t...

Many Wire-EDM machines have adopted the pulse generating circuit using low power for ignition and high power for machining. However it is not suitable for finishing process since the energy generated by the high voltage sub-circuit is too high to obtain a desired fine surface, no matter how short the pulse on time is assigned. For the machine used in this research, the best surface roughness Ra...
