The impact of chosen factors on feeding effectiveness of fodder area in farms specializing in milk cattle breeding

Abstract

This paper identifies and examines land use in the production of animal protein necessary to supply people nutritional demand. As the ratio describing land use, the author assumed the quantity of protein in meat and milk produced per 1 ha of land intended for fodders production for milk cattle in specialist farm /year. The second ratio describing the above mentioned research problem was the number of people whose annual demand for minimum necessary protein quantity can be supplied from protein production on 1 ha cattle fodder area. The levels of the first ratio were analyzed dependently upon the values of five chosen factors. The factors which had the greatest impact on the ratios of land use are as follows: soil quality and cow milk efficiency. The levels of the second analyzed ratio were determined basing upon the value of the first ratio as well as the assumed three possible shares ( 25%, 50% and 75%) of animal protein in total annual protein demand of a person weighing 70 kg. It should be noted that the number of persons for whom one can produce necessary annual protein quantity in milk and meat of cattle from 1 fodder area ha hesitated from 6.9 to 37.3 persons.
