Advantages
When laying hens change feather, they need badly methionine. In case deficiency of methionine in the organism of animals and poultry, there appear a loss of appetite, anaemia, atrophy of musculature, fatty liver, dysfunction of kidney, reduction of breeding efficiency, reduction of growth rate of the young animals and of mature poultry productivity, disorder of poultry feathering and ability to get feathering (ruffle feathers, their dullness, frailness and falling out). As a result, a low efficiency of fodder use is observed. The formation of white-egg is retarded and, therefore, reduces mass of eggs. There appear the distortion of lipidic exchange, which is characterized by the fatty infiltration and the dystrophy of liver. At the simultaneous lack of vitamin E the deficit of methionine results in development of chickens’ muscular dystrophy and dermatitis of feet.Specification
