Cotton is traditionally the most important natural fibre in the apparel industry because of the comfortable wearing comfort and durability of cotton textiles. The chemical finishing of cotton aims to further improve the quality of the cotton fibre, either to overcome some disadvantages of the apparel or to establish additional desirable properties. This paper highlights some current trends in c...

Angus-cross steers (n = 198; 270 kg of BW; 8 mo) were used in a 3-yr study to assess the effects of winter stocker growth rate and finishing system on LM proximate, fatty acid, cholesterol, vitamin, and mineral composition. During the winter months (December to April), steers were randomly allotted to 3 stocker growth rates: low (0.23 kg/d), medium (0.45 kg/d), or high (0.68 kg/d). At the compl...

Nutrient management plans are used to reduce non-point source pollution from animal operations. These plans require manure analysis and use indices to determine nutrient availability. This study evaluated a modified method for determining nitrogen fractions in swine slurry stored under slatted floors, calculating plant available nitrogen, and characterizing nitrogen fractions by holding pit dep...

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...
