Miroshnitcenko I. Efficiency different levels of magnesium in the rations of pigs on fattening

Object of research : sapling of pigs on fattening, mixed fodder, magnesium, excrements, blood, internalss, meat. Purpose of research : experimental determination of the most effective maintenance of magnesium in rations on his influences on the indexes of growth and fattening, digetibility of nutritives, balance of nitrogen, magnesium, calcium, phosphorus, meat productivity, quality of meat and economic efficiency. Methods of researches: generally accepted zootechnic, spectrophotometry, histological, morphometric, biometrics. Teoretical and practical results: the most effective level of magnesium was set in the rations of sapling of pigs on fattening which enables in practical terms to promote their productivity. Novelty of inculcated: in the first grounded the most effective maintenance of magnesium in SV of rations in an amount 4,8 g/kg. Degree of introduction: it is inculcated in economies on the production of pork, mixed fodder industry and educational поцесс. Industry of the use: agriculture and mixed fodder industry
