Abstract:

In this paper published economic analysis of the impact of the four food factors in the milk production and average weight of newborn calves and use of the mathematical models in the livestock sector. The main purpose of this paper is the use of modern methods in economic analysis of use of resources in a farming complex. Livestock development in general and milk production in particular is closely linked to many factors which are the main breeding. This study analyzes the economic impact of four components ration (wet food, dry food, concentrate and mineral salts) used for milk production and average weight of newborn calves. The study was conducted in Lushnje district. Are analyzed and processed data feeding phases (1-up in 150 days lactation, 2over 150 days lactation and 3- period of drying), milk production and average weight of newborn calves for a period of 6 years. This study used approaches through approximation with the method of undetermined coefficients to solve systems of constraints and production function to analyze the impact of the three components of the ration on milk production, weight of calves and quantity of manure. This study confirms that balanced nutrition is a major factor in increasing economic efficiency of farms. In proportion to the daily ration we have to be awarded: 56.8 % wet food, dry food 29.43% , 13.56 % koncetrat and 0.21 % mineral salts of 48.8 kg food per day.

Keywords: optimal structure; milk production; nutritive factors; Bernstein polynomial approximation; the food ration.
