High dietary taurine effects on feline tissue taurine concentrations and reproductive performance

Article Abstract:

The long-term effects of taurine supplementation on the nutrient's concentration in the brain and its effect on feline reproduction were analysed to determine the impact of taurine supplements in cat food on cat's health and productivity. Significant taurine supplementation over normal levels slightly improved reproductive performance in cats. Cats on high taurine diets also gave birth to heavier kittens with larger brains at weaning. Neither dams nor kittens exhibited adverse reaction to the taurine supplement. Further, it was shown that adult and newborn cats did not accumulate as much taurine in their brain tissues as juvenile kittens had.

Taurine balance is different in cats fed purified and commercial diets

Article Abstract:

Taurine losses were evaluated in six taurine-replete and four taurine-deficient cats maintained on different types of diets using digesta from the terminal ileum. Comparison of the taurine losses of the different cats suggests that taurine lost in the ileum came from endogenous sources because the amount of taurine lost was comparable for both taurine-replete and taurine-deficient cats. Heat processed commercial catfood was shown to cause the highest level of taurine loss. This explains the failure of some heat-processed commercial pet food to maintain adequate serum taurine level.

Dietary protein source (soybean vs. casein) and taurine status affect kinetics of the enterohepatic circulation of taurocholic acid in cats

Article Abstract:

Taurine is a key requirement for proper enterohepatic circulation of bile salts, which is also affected by the amount and type of dietary fiber and protein. The effects of protein source on taurine loss during enterohepatic cycling of taurocholic acid in cats were determined. The results showed that cats fed a soybean diet had a greater taurocholic pool size and had higher entry and irreversible loss rate for taurocholic acid than cats fed with casein diet.
