In rations that contain >18.8 kj ME/g, the concentration of all other nutrients should\nbe increased proportionately,- rations <16.7 kj ME/g should not be corrected for energy.\n2 Although a true requirement for fat per se has not been established, the minimum level was based on recognition of fat as a source of\nessential fatty acids, as a carrier of fat-soluble vitamins, to enhance palatability, and to supply an adequate energy density (NRC 1986).\n3 In general, if the mean urine pH of cats fed ad libitum is not below 6.4; the risk of struvite urolithiasis increases as the magnesium\ncontent of the diet increases.\n4 Because of very poor bioavailability,\n\niron from carbonate or oxide sources that is added to the diet should not be considered as contributing\n\nto the level of nutritional iron in the diet.\n5 Add 10 mg vitamin E above minimum level per gram of fish oil per kilogram of diet (NRC 1986).\n6 Vitamin K does not need to be added unless diet contain >25% fish on a dry matter basis.\n7 Because processing may destroy up to 90% of the thiamin in the diet, allowances in formulation should be made to ensure the minimum\nnutrient level is met after processing.\n8 Biotin does not need to be added unless diet contains antimicrobial or antivitamin compounds (NRC 1986).\n9 Methionine may substitute for choline as a methyl donor at a rate of 3.75 pans for 1 part choline by weight when methionine\n6.2 g/kg (NRC 1986).\n\nexceeds\n\n2538S\n","sources":[],"tokens_estimated":1610,"generated_at":null,"tip":"Use /api/v1/topics to discover more topics. /api/v1/nutrient for precise single-point queries. /api/v1/cross_compare for 2-3 standard comparisons."}
