The research aimed mainly to study the economics of production and marketing of milk farms in the New Valley Governorate, this can be achieved through statistical estimation of production and costs functions, and estimating the most important indicators of the economic efficiency of milk farms in the sample of the study according to the different production capacities, as well as a study of the marketing pathways for milk farms in the New Valley Governorate, in addition to estimating margins, marketing efficiency, and distributing consumer pound, and to identify the most important production and marketing problems facing milk producers the study sample and proposals for solving them. in achieving its objectives, the research relied on the use of descriptive and quantitative economic analysis methods. It depends on field data for a sample of milk farms in the New Valley Governorate for the agricultural season 2020/2021, where their number reached 158 farms, and they were distributed over three production capacities. The results of the research explained that the most influential factors in the quantity of milk produced are the quantity of green fodder, the quantity of concentrated fodder, veterinary care, the length of the milking season, and estimating the function of total costs at the sample level, the results indicated that the elasticity of costs amounted to about 1.03, and this indicates that the sample producers are working in the economic production stage. Using the criteria of economic efficiency, the results showed that the third production capacity is more economic efficiency than the first and second production capacities, the net return increases by increasing the production capacity of the farms, and this capacity also ranked first in relation to the rate of return on the invested pound, which amounted to about 0.51, the net return to the head in that capacity was higher than the other production capacities, as it amounted to about 7.95 thousand pounds. The results of distributing the consumer's pound indicate an increase in the producer's share of the consumer's pound and the convergence of the share of the wholesaler and the retailer, and the high share of the product is due to the high production costs of feed, veterinary care, and labor. It was also found that the distribution of the consumer's pound is unfair, as the producer receives about 72.1%, while middlemen get about 27.9% of the consumer's pound, and the proportion of mediators distributed by 13.5% for the wholesaler and about 14.4% for the retail trader, this shows the low share of middlemen from the consumer's pound. By estimating the marketing efficiency of milk farms in the study sample was estimated at 66.5%, 69.2%, 71.6%, and 69.1% at the level of the three production capacities and the total sample, respectively. it was clear from this that the marketing efficiency was high at the level of milk farms in the sample of the study. In light of these results, the research recommends the following: (1) Working to provide concentrated feed at reasonable prices, while giving it subsidies, and expanding the agriculture of nontraditional fodders such as silage, rice straw, and corn Stover, (2) Expanding the establishment of milk collection centers to prevent traders from controlling prices, and achieving better prices for producers, in addition to ensuring the safety and quality of milk during its circulation, (3) Work to establish links for milk producers, whose mission is to collect and market milk, and (4) Activating the role of veterinary units and providing fortifications at reasonable prices, with the need to providing guidance services to producers.
