An experiment was conducted to compare the effect of dietary sodium selenite and selenomethionine on selenium and α-tocopherol concentration in breast meat, oxidative stability of meat in broilers, and on growth performance, but only as an unimportant criterion in this case. Sexed broiler cockerels Ross 308 were allocated to 3 dietary treatments, each comprising 100 chickens. The basal diet was...

Stools from asymptomatic volunteers on diets containing red meat, whole blood, or high fiber were analyzed for their content of hemes and dicarboxylic (heme-derived) porphyrins by the "HemoQuant" assay, the "Hemoccult" test, and "high-performance" liquid chromatography (HPLC). In 49 subjects, ingestion of red meat increased HemoQuant-determined combined fecal heme plus dicarboxylic porphyrins b...

Modem turkeys, like swine, have been subjected to intense genetic selection for ‘rapid lean muscle growth. Because selection has been based on only a few traits that are primarily of economic importance, little attention has been paid to the functional muscle physiology. Selection to achieve maximal growth performance may partially be responsible for increased incidence of such conditions as le...

Feed costs are a major cost component of pig production and the optimal use of feed for production is therefore of high importance in an economic and sustainable pig industry. The amount of food eaten by the growing pig is used for maintenance and growth which includes lean meat as well as fat growth. The aim in pig production is to produce lean meat most efficiently which is achieved by optimi...

Two experiments were undertaken to study the effects of graded levels of dietary protein and energy on the performance of growing meat-type ducklings. The results of Experiment 1 indicated that meat-type ducklings. gave satisfactory weight gain and feed utilisation on starter and finisher diets containing 18 percent protein with 3.00 Meal ME/kg. There were no marked differences in performances ...

Abstract This review covers the current situation of use Spirulina in poultry diets and discusses its benefits challenges with particular emphasis on effect supplementation production performances meat quality. Feed enriched influences broilers’ health by improving their immune response gut function increasing PUFA pigment content meat. However, despite numerous studies, broiler performance rem...

Betaine is donor of methyl groups and can partially replace methionine in diets for this purpose. The objective of this study was to evaluate three sources of betaine in partial substitution of methionine supplement in broiler diets. The Cobb-500 broiler chickens were allocated in a completely randomized experimental design with 5 treatments and 7 replicates of 49 birds each. The positive contr...

the quality control of microbial contamination in meats consumed in restaurants of university of tehran was taken into consideration. for this reason, 100 sterile samples were taken from 4 central restaurants, from may until october 1995, the samples were as follows: 12 samples of meat, 50 samples of chopped meat and 38 samples of minced meat. all of the samples were examined to search for meso...

Decisions as to the disposition of swine carcasses with lesions attributable to a mycobacterial infection are based upon a lesion criterion which is used as a diagnostic test by federal meat inspectors. Using this criterion, a federal meat inspector classified 58 of 100 pigs as "passed for cooking" and the other 42 pigs passed. Of the 58 pigs passed for cooking and the 42 pigs passed, mycobacte...
