Based on the comparative analysis of production performance, egg quality and muscle quality characteristics, the correlation between polydactyly phenotype and product quali- ty of Beijing fatty chickens was analyzed, aiming at providing the reference for development and utilization of product quality and breeding of Beijing fatty chickens. [ Method] Egg laying/meat dual-purpose type Beijing fatty chickens were selected and divided into three groups (bilateral four-toed, unilateral five-toed and bilat- eral five-toed) with four replications, 60 chickens per replications, 240 chickens per group. The production performance (weight, laying rate and egg weight), egg quality (Haugh unit) and muscle quality (pH, water-holding capacity, Warner-Bratzler shear force, TPA, nucleotide metabolites) characteristics of Beijing fatty chickens were determined. [ Result] The weight of 120-d-old and 240-d-old bilateral five-toed Beijing fatty chickens was slightly higher than that of bilateral fourtoed and unilateral five-toed Beijing fatty chickens, with no significant difference (P 〉0.05) ; egg weight of 160-d-old bilateral five-toed Beijing fatty chickens was significantly higher than that of bilateral four-toed and unilateral five-toed individuals ( P 〈 0.05 ). Water-holding capacity of leg muscles of bilateral five-toed Bei- jing fatty chickens was significantly superior to that of unilateral five-toed and bilateral four-toed individuals (P 〈0.05 ). The hardness, gumminess and chewiness of leg muscles of bilateral five-toed Beijing fatty chickens were significantly lower than that of unilateral five-toed and bilateral four-toed individuals ( P 〈 0.05 ), but the coherence and elasticity were remarkably higher compared with unilateral five-toed and bilateral four-toed individuals ( P 〈 0.05 ). Warner-Bratzler shear force of leg muscles of bilateral five-toed Beijing fatty chickens was significantly higher than that of other individuals ( P 〈 0.05 ). There was no significant difference in flavor substances among Beijing fatty chickens with different polydactyly phenotypes (P 〉0.05). [ Conclusion] At early stage, the weight and egg weight of fivetoed Beijing fatty chickens were slightly superior to that of four-toed individuals. In addition, Beijing fatty chickens with different polydactyly phenotypes displayed excellent muscle quality. Overall, leg muscle quality of Beijing fatty chickens exhibited a greater correlation with polydactyly phenotype than chest muscle quality.展开更多

Semi structured questionnaire has been employed to executive and technical managers of manufacturing industries of various size and specialism across the country. Stratified random sample method by region was used to select sample industries for the study. The samples used for this study are industries mainly from Oromiya, Addis Ababa, Tigray, Amara, SNNP and Diredawa regions proportional to their size of the available industries. Methods: Exploratory method and descriptive statistics was used for data analysis. Available documents and reports related to quality control policy of the selected companies were investigated. Results and Discussions: The number of manufacturing industries involved in this study was 44. Of the sampled manufacturing industries about 60% are from Oromiya and Addis Ababa regions. It has been reported that 100% of the respondents said that the importance of quality control tools is very important to their organizations’ productivity and quality improvement (Figure 3). Quality control professionals were also asked the extent to which quality control system is working in their industry and majority of the respondents (45%) have indicated that quality control system is working to some extent in their respective industries (Figure 18). Conclusions and Recommendations: Most of the quality department of the industries did not fully recognize the importance of statistical process control as quality control tools. This is mainly due to lack of awareness and motivation of the top managements, shortage of man power in the area, and others together would make it difficult to apply quality control tools in their organization. In general, the industries in Ethiopia are deficient in vigor and found to be stagnant hence less exposed to a highly competitive market and don’t adopt the latest quality control techniques in order to gain knowledge about systems to improve quality and operational performance. We conclude that quality management system has to be established as an independent entity with a real power and hence the quality control department which is responsible for quality can make an irreversible decision with respect to quality of any given product. Moreover, the concerned bodies (government and ministry of industries) should give attention and work together with universities to ensure how these statistical process control techniques could be incorporated in a curriculum of the universities at higher levels in degree and masters programs. Furthermore, different trainings which could improve quality and efficiency of their respective management system should be given as short and long term to the employees including top and middle managers found in various industries relevant to their process.展开更多

In this study, a survey was conducted on a sample of pig slaughtering and processing firms in Zhejiang, China through personal interviews and emails. The aim of this study was to examine the determinants of firm behavior on the implementation of voluntary traceability systems with more stringent standards and controls than those of the mandatory system in China. The results revealed that motivation based on product quality improvement, capital ability and role perception (business type) had significantly positive relationships with a firm's voluntary traceability. Other incentives, such as operation improvement, recall risk reduction, reduced occurrence of safety issues, and technical strength were not found to be supportive in our study. This study provides an opportunity to better understand the determinants of firm behavior on voluntary traceability, particularly in light of the fact that some Chinese firms are facing the threat of criminal action for the use of illegal additives and the abuse of Clenbuterol. Policy recommendations on encouraging the implementation of pork safety voluntary traceability by hog slaughtering and processing firms are also discussed.展开更多

BCAA(isoleucine, leucine and valine) regulate many key signaling pathways, the most classic of which is the activation of the m TOR signaling pathway. This signaling pathway connects many diverse physiological and metabolic roles. Recent years have witnessed many striking developments in determining the novel functions of BCAA including:(1) Insufficient or excessive levels of BCAA in the diet enhances lipolysis.(2) BCAA, especially isoleucine, play a major role in enhancing glucose consumption and utilization by up-regulating intestinal and muscular glucose transporters.(3)Supplementation of leucine in the diet enhances meat quality in finishing pigs.(4) BCAA are beneficial for mammary health, milk quality and embryo growth.(5) BCAA enhance intestinal development, intestinal amino acid transportation and mucin production.(6) BCAA participate in up-regulating innate and adaptive immune responses.In addition, abnormally elevated BCAA levels in the blood(decreased BCAA catabolism) are a good biomarker for the early detection of obesity, diabetes and other metabolic diseases. This review will provide some insights into these novel metabolic and physiological functions of BCAA.展开更多

BCAA(isoleucine, leucine and valine) regulate many key signaling pathways, the most classic of which is the activation of the m TOR signaling pathway. This signaling pathway connects many diverse physiological and metabolic roles. Recent years have witnessed many striking developments in determining the novel functions of BCAA including:(1) Insufficient or excessive levels of BCAA in the diet enhances lipolysis.(2) BCAA, especially isoleucine, play a major role in enhancing glucose consumption and utilization by up-regulating intestinal and muscular glucose transporters.(3)Supplementation of leucine in the diet enhances meat quality in finishing pigs.(4) BCAA are beneficial for mammary health, milk quality and embryo growth.(5) BCAA enhance intestinal development, intestinal amino acid transportation and mucin production.(6) BCAA participate in up-regulating innate and adaptive immune responses.In addition, abnormally elevated BCAA levels in the blood(decreased BCAA catabolism) are a good biomarker for the early detection of obesity, diabetes and other metabolic diseases. This review will provide some insights into these novel metabolic and physiological functions of BCAA.
