Effects of distance and barriers between resources on bone and tendon strength and productive performance of broiler chickens.

Lameness or leg weakness is becoming an important problem in broilers selected for rapid growth, and although the causes are not known, sedentary behavior could be a cause. Two experiments were conducted to study the effects of distance and the presence of ramps between resources (feed and water) on bone and tendon strength, ability to stand, and productive performance. In experiment 1, straight run Ross 708 chicks (n = 1,260) were randomly assigned to 1 of 3 treatments: 1.

Dietary supplemented and meat-added antioxidants effect on the lipid oxidative stability of refrigerated and frozen cooked chicken meat.

The oxidation of fatty acids decreases the quality and shelf-life of meats. To reduce this process, dietary supplemented and meat-added antioxidants were evaluated on the lipid oxidative stability of cooked chicken meat. Broilers were fed 2 levels of vitamin E (10 or 100 mg•kg(-1) of feed; VE-10 and VE-100, respectively) or oregano essential oil (100 mg•kg(-1) of feed; OR-100).

Effects of dietary combination of n-3 and n-9 fatty acids on the deposition of linoleic and arachidonic acid in broiler chicken meats.

To minimize the amount of n-6 fatty acids in broiler chicken meat, 120 Cobb × Ross male broilers were divided into 6 different groups and fed a basal corn-soybean meal diet containing 5% fat from 5 different lipid sources: 1) a commercial mix of animal and vegetable oil, 2) soybean oil and olive oil (2.5% each), 3) flaxseed oil and olive oil (2.5% each), 4) flaxseed oil, eicosapentaenoic acid (C20:5; EPA; n-3), and olive oil (2.

Effects of dietary oregano essential oil and vitamin E on the lipid oxidation stability of cooked chicken breast meat.

The antioxidant effect of oregano essential oil and vitamin E was evaluated in cooked chicken breast meat. In total, 480 broilers were randomly assigned to 6 treatments and 4 replications. Broilers were raised with a corn-soybean meal diet including either crude soybean oil or acidulated soybean oil soapstock, each supplemented with vitamin E at 10 or 100 mg or oregano essential oil at 100 mg/kg of feed.

Effect of various refrigeration temperatures on quality of shell eggs.

Background: The objective of this study was to evaluate the effects of low storage temperatures on shell egg quality.

Results: Approximately 2100 shell eggs were collected and stored at - 1.1, 0.
