Identification of genes related to growth traits from transcriptome profiles of duck breast muscle tissue

Sarcoplasmic, myofibrillar, and non-protein nitrogen fractions extracted from chicken leg and breast muscle tissue after heating to 40, 50, 60, 70, and 80 C were compared with non-heated samples. The pH modifications that occurred during heating were also observed. The myofibrillar fraction was more heat-sensitive than the sarcoplasmic proteins with a slight difference in sensitivity occurring between the leg and breast muscle tissues. Both of these fractions were only approximately 10% soluble after heating to 70 C with only slight alterations caused by additional heating to 80 C. The non-protein nitrogen fractions decreased slightly during the heating cycle and remained more than 90% soluble after heating to 80 C. Initially, pH of breast muscle was lower (P < .05) than leg muscle and the breast sample increased in pH more rapidly than the leg sample during the heating cycle.

The structure of pigeon breast muscle mitochondria was studied both in whole muscle tissue and in mitochondrial fractions separated by differential centrifugation. No evidence was found to indicate that the mitochondria of pigeon breast muscle differ in any fundamental way from those of other tissues. In particular the absence of an enveloping membrane, claimed in recent reports, was not confirmed. The structure of the lipide bodies present in muscle has been described, and compared with that of similar bodies in other tissues.

Abstract Background: G-protein subunit beta 1 like ( GNB1L ) encodes a G-protein beta-subunit-like polypeptide. Chicken GNB1L is upregulated in the breast muscle of high feed efficiency chickens, and its expression is 1.52-fold that in low feed efficiency chickens. However, no report has described the effects of GNB1L indels on the chicken carcass and growth traits.Results: This study identified a 31-bp indel in the 5' untranslated region (UTR) of GNB1L and elucidated the effect of this gene mutation on the carcass and growth traits in chickens. The 31-bp indel showed a highly significant association with the body weight at 8 different stages and was significantly correlated with daily gains at 0 to 4 weeks and 4 to 8 weeks. Similarly, the mutation was significantly associated with small intestine length, breast width, breast depth and breast muscle weight. Moreover, DD and ID were superior genotypes for chicken growth and carcass traits.Conclusions: These results show that the 31-bp indel of GNB1L significantly affects chicken body weight and carcass traits and can serve as a candidate molecular marker for chicken genetics and breeding programs.

The aim of this study was to determine the effects of organic selenium supplemented to broiler feed on the selenium content and fatty acid profile in broiler breast muscle tissue. The study was carried out on 60 male Ross 308 broilers that were slaughtered at the age of 42 days. After day 21, the broilers were divided into three experimental groups (P1, P2, P3), and each group was given separately prepared finisher diets that contained 18% of crude protein and 14.67 MJ/kg ME (finisher diet contained 6% of oil, of which 3% was sunflower oil, and 3% was linseed oil added for the purpose to increase portion of α-linolenic fatty acid. The content of organic selenium (Sel-Plex®) supplemented in the finisher diet was as follows: no selenium, 0.3 mg Se/kg of feed and 0.5mg Se/kg of feed for P1, P2 and P3 group, respectively. It was determined that the group P3 had a significantly higher (P < 0.05) content of selenium in breast muscle (0.256 mg Se/kg of tissue) than group P2 (0.183 mg Se/kg of tissue) and P1 (0.087 mg Se/kg of tissue). Supplementation of selenium to feed at the amount of 0.3 mg/kg affected the fatty acid profile in breast muscle tissue by increasing portions of α-linolenic, eicosapentaenoic, docosapentaenoic and docosahexaenoic acids and total n3 polyunsaturated fatty acids, and by lowering portion of total saturated and monounsaturated fatty acids.

Thymus Vulgaris

The absorption and metabolism of phytogenic feed additives in poultry is studied related to the metabolism and deposition of their main compounds in tissues intended for food production. Fifty-six non-sexed Ross 308 broilers were allocated to seven dietary treatments and fed a diet containing graded levels of thyme ( Thymus vulgaris L.) essential oil (EO) (0, 0.01, 0.02, 0.03, 0.04, 0.05, 0.1%, w/w). Thymol concentration was measured in plasma, liver, kidney and breast muscle tissue using solid phase micro-extraction followed by gas chromatography/mass spectrometry. We found the highest concentrations of thymol in kidney and plasma, and the lowest in breast muscle and liver. Thymol content in plasma and kidney significantly increased when 0.05 and 0.1%, w/w, EO and in liver and breast muscle only when 0.1%, w/w, EO was added to the diet ( p<0.05). Our results indicate intensive metabolism of thymol in liver and its accumulation in kidney tissue. We confirm low deposition of thymol in the muscle tissue. It is necessary to keep in mind the selection of a sufficient concentration of EO in the feed additive for animals without the risk of thymol residues in edible tissues.
