Study On The Prouduction And Applaction Of Protein Feed For Dairy Cow From Apple Pomace Through Mixed Fermentation

The suitable inoculation proportion and strain combination for fermentation of apple pomace were obtained by single strain and mixed strain combination experiment; the optimum nitrogen source and its inoculation ratio of the culturing medium for apple pomace fermentation were obtained by solid-state fermentation experiment; the suitable cultivate time, the ratio of material to water, the thickness of medium and the fermentation temperature were obtained by perpendicular orthogonal L9(34) test; the influence of milk producing ability and health conditions of the dairy cattle fed by fermented apple poamce were testified by 2-time feeding experiment.Results show that when the fermentation strain ratio of Geotrichum candidum, Candida tropicalis, and Trichodermn Konihgii is 2: 2: 1, and the inoculation is about 10%, Ureal.5%, Ammonium sulfate2%, material to water ratio 1: 0.8, the thickness of medium 30cm, tempreture32C, cultivate time 72h, the content of raw protein in the fermented apple pomace was increased to 31.2%, in which, the 17 amino acids were remarkably increased ; the content of raw cellulose was reduced to 12%, methionine and glutamic acid were increased to 200%.The fermented apple pomace can make each dairy cattle produce more milk by 3.5 kg/day, meanwhile milk fat and milk protein were increased , the somatic cell count and the disease rate of bovine mastitis were decreased. The fermented apple can help improve the dairy cattle's health conditions.There is no discharging of the waste water and residues in the production, which basically solves the problem of environmental pollution of apple pomace, provides new source of feeding protein for stock raising, and bring the significant profits for the enterprises and fruit farmers.
