採卵養鷄農家의 經營分析과 生産性 提高 方案
摘要
1. The primary purpose of this study was to analyse the current status of layer operations in Korea related to management practices and input and output relationship in egg production by surveying 150 egg producers throughout the country. Based on this primary information, this study attempted to illustrate a model layer farming budget. 2. The average size of the layer operations included in this survey was 7,969 hens per farm during the period from September 1, 1980 to August 31, 1981. However, about 80% of the producers started the layer farming with smaller scales than 3,000 layers and less funds than 10 million won during the later half of 1960s and the early half of 1970s. About 72% of the farmers were graduates from high school or college. These egg producers listed that lack of funds and poor production and management skills are the most important problems in the operation. 3. The farmers used to purchase baby chicks from the well-known hatcheries and commercial mixed feeds on one or two months' credit. While the eggs were sold to wholesalers and/or assemblers. Few of the producers market their products directly or cooperatively through the industry organization. 4. On the average, every farmer raised pullets two times a year and approximately 55% of farmers practiced 'All in-all system for the replacement of layers. Dubbing was practiced by a few farmers, debeaking and restricted feeding by 70-80% of farmers and artificial molting by 50% of sampled egg producers. Almost all of the large scale operations have kept fairly reasonable records, but only one half of the small producers have recorded information on feed consumption and financial matters. 5. The labor used per 100 hens a year was 106 man hours on the average, which means one man alone can manage approximately 3,400 hens. Of 106 hours, 40% or 42 hours was allocated for feeding and watering, 30% for collecting, grading and packing of eggs, and16% for cleaning and waste management. The priority for mac
