Quality Poultry Meat Production
Korean Journal of Poultry Science, volume 26, issue 1, 1999, Pages 1~25
Concerns about meat quality, including chicken meat, for the human diet has led to many attempts to manipulate the carcass fat and increase the eating quality. For actual eating quality, the birds must be grown and finished in a manner that results in meat that are tender, succulent and of good flavor, as well as being free from any foreign taint, flavor or safety hazard. Tenderization treatment with high voltage(820V) electrical stimulation and prechill muscle tensioning would improve the tenderness of chicken meat. Proper programs for the withdrawal of feed and water require a team approach for maximizing yield of meat and minimizing carcass contamination. Also effding of supplemental levels of-tocopherol to poultry with vegetable or fish oils increases of desirable polyunsaturated fatty acid(PUFA) content and stablizes the meat against rancidity and fish off-flavors. The nutritional effects of varying dietary ingredients on broiler carcass fat content are also important. Increasing the levels of energy in the ration increases the carcass fat content, while increasing the proteing levels decreases carcass fat content. Supplement-tation of poultry diets with amino acids such as methionine, lysine, glycine and tryptophan as well as amino acid such as well as amino acid mixtures can reduce body fat deposition. Normal stress leads to chicken muscular damage resulting in reduced meat quality, but this can be controlled by preslaughter management practices. Feed manufactures can utilize ntilize nutrient modulation to control pale soft exudative(PSE)syndrome. Finally, the success in poultry meat production depends on the consistent achievement of carefully selected levels of quality. Quality assurance should be the wider function of incorporating quality into the production system and the combination of motivating quality into actions and operations.
The Anatomical Study on the Distribution of Oviductal Vessels in Korean Native Pheasants
Korean Journal of Poultry Science, volume 26, issue 1, 1999, Pages 27~33
The distribution of oviductal vessels of eight Korean native pheasants was observed after Latex casts of vessels. Latex was injected into thoracic aorta and posterior vena cava of these birds for cast preparation. The results were as follows: 1. The arteries suppling oviduct of the Korean native pheasants contained A. oviductalis cranialis, media, caudalis and vaginalis. The veins drainaging oviduct were stretched along the following ateries and all of the oviductal vessels were situated on the left side of the body. 2. The anterior oviductal artery arose from the pubic artery of the left external iliac artery and distributed to the infundibulum and the magnum of the oviduct. 3. The middle oviductal artery arose from the left sciatic artery and distributed to the isthmus and shell gland of the oviduct. 4. The caudal artery arose from the left internal pudendal artery of the median sacral artery and distributed to the caudal part of uterus and the cranial part of vagina. 5. The vaginal artery arose from the left internal pudendal artery of median sacral artery and distributed to the caudal part of vagina.
Sales Strategies for Eggs and Special Brand Eggs in Japan I. Meaning of Special Brand Egg Production to Poultry Farm Management and Its Economics
Korean Journal of Poultry Science, volume 26, issue 1, 1999, Pages 35~42
According to the importance(production ratio) of special brand eggs, poultry farma can be classified into four types(Types I to IV). A close relation can be observed between these types and farm scale. Special brand eggs used to be the speciality of small-scale, suburban poultry farms. Recently, however, the production of these eggs has been adopted by medium and large farms, too, and is increasing throughout Japan. In particular, small-scale farms specializing in these eggs have attained a high profit and take a characteristic management from as opposed to large-scale poultry farming that adopts the \"small profit and quick returns\" strategy. Because of this, the meaning of special brand egg production to farm management differs according to farm scale. For small poultry farmers, it means securing a high profitability and for medium and large producers, improving the corporate image or meeting the needs for assortment of retailers.
Sales Strategies for Eggs and Special Brand Eggs in Japan II. Structure of Production Market Strategy of Special Brand Eggs
Korean Journal of Poultry Science, volume 26, issue 1, 1999, Pages 43~50
The features of special brand eggs are growing more and more diverse and it is hard to draw a clear distinction between these and ordinary (no-brand) eggs. Special brand eggs range from those with objectively recognizable characteristics to those given only an unsubstantial product image and price differentials are among them great, too. The relation between product features and prices is unclear. Special brand eggs are the commodity whose characteristics are the vaguest of all livestock products. Farm's brand eggs produce a high profitability to producers is they are directly sold to consumers, by, for example, home-delivery service. But if they are sold to supermarkets, etc., producer's (poultry farmer's) income becomes lower by the amount of distributors' margin, reducing the profitability substantially. Thus how to increase the ration of retailing is important for farmers to secure a high profit. The sales strategies of poultry are the combination of two elements, that is, new product development (product differentiation) and creation of new market. But it is difficult for special brand egg producers to develop products with clear characteristics (use value) distinct form ordinary eggs and so these producers depend on the factors of appearance, such as the color of egg shells and package. Special brand eggs manage to keep their marketable value by the combination of the few product features and product image. Thus NB eggs from feed producers have a great market-ability since they can take advantage of the power of patents and TV commercials. However, market differentiation affects profitability much more than product features and price gaps are very wide between directly sold and wholesaled eggs. The producers of special brand eggs have come to the turning point where they have to decide whether they will content with being the subcontractors for NB and PB eggs or they will continue to keep their independence in production and marketing.
Effects of Red Pepper Seed Oil Meal Supplementation on Performance and Abdominal Fat Accumulation in Broilers
Korean Journal of Poultry Science, volume 26, issue 1, 1999, Pages 51~56
This experiment was conducted to determine the effect of dietary red pepper seed oil meal (RPSOM) on the performance and the fat pad content in broiler chicks. feeding trial was conducted with 360 birds broiler chicks for 8 weeks. The levels of dietary RPSOM were 0, 5, 10 and 15% and mixed in diet consisting of corn and soybean meal. Body weight, feed intake, feed conversion and mixed in diet consisting of corn and soybean meal. Body weight, feed intake, feed conversion and viability were not significantly different among treatments. The percentage of abdominal fat and skin color were not significantly differents among treatments. The results of the feeding trial show that RPSOM can be used within 10% in broiler diet.
