Evaluation of meat meal, chicken meal, and corn gluten meal as dietary sources of protein in dry cat food.

The nutritional value of meat meal (MM), chicken meal (CM), and corn gluten meal (CGM) as dietary sources of protein in dry food formulated for adult cats was evaluated. Twelve healthy adult cats (11 males and 1 female) were used. Dry diets containing MM, CM, or CGM as the main protein source were given for a 3-week period in a 3 x 3 Latin-square design.

Evaluation of effects of dietary carbohydrate on formation of struvite crystals in urine and macromineral balance in clinically normal cats.

Objective: To evaluate effects of dietary carbohydrate on urine volume; struvite crystal formation; and calcium, phosphorus, and magnesium balance in clinically normal cats.

Animals: 21 healthy adult cats (15 sexually intact males and 6 sexually intact females).

Procedure: Diets containing no carbohydrate source (control diet), control plus starch, or control plus fiber were given in a 3 X 3 Latin-square design.

Effects of a high-protein diet versus dietary supplementation with ammonium chloride on struvite crystal formation in urine of clinically normal cats.

Objective: To evaluate the effects of a high-protein diet versus dietary supplementation with ammonium chloride (NH4Cl) on struvite crystal formation in the urine of clinically normal cats by measuring the urine concentration of hydrochloric acid (HCl)-insoluble sediment, urine pH, struvite activity product (SAP), number of struvite crystals in urine, and urine volume.

Animals: 23 healthy adult cats.

Procedure: Urine was fractionated by centrifugation with subsequent extraction of the sediment with 1 N HCl (study 1).

Comparison of corn gluten meal and meat meal as a protein source in dry foods formulated for cats.

Objective: To compare the nutritional value of corn gluten meal (CGM) and meat meal (MM) as a dietary source of protein in dry food formulated for adult cats.

Animals: 8 healthy adult cats (4 males and 4 females).

Procedure: Diets containing CGM or MM as the main protein source were each fed for a 3-week period in a crossover study.
