Abstract
Ruminants' milk is commonly used for supplying nutrients to infants when breast milk is unavailable or limited. Previous studies have highlighted the differences between ruminants' milk composition, digestion, absorption, and fermentation. However, whether consuming different ruminants' milk impact the appearance of the circulatory blood metabolites in the early postnatal life is not well understood. The analysis conducted here aimed to determine the effect of feeding exclusively whole milk from bovine, caprine or ovine species to pigs, approximately 7 days-old for 15 days, on circulatory blood plasma metabolites. Relative intensities of plasma metabolites were detected using a liquid chromatography-mass spectrometry based metabolomic approach. Seven polar and 83 non-polar (lipids) metabolites in plasma were significantly different (false discovery rate < 0.05) between milk treatments. These included polar metabolites involved in amino acid metabolism and lipids belonging to phosphatidylcholine, lysophosphatidylcholine, sphingomyelin, and triglycerides. Compared to the caprine or bovine milk group, the relative intensities of polar metabolites and unsaturated triglycerides were higher in the peripheral circulation of the ovine milk group. In contrast, relative intensities of saturated triglycerides and phosphatidylcholine were higher in the bovine milk group compared to the ovine or caprine milk group. In addition, correlations were identified between amino acid and lipid intake and their appearance in peripheral blood circulation. The results highlighted that consuming different ruminants' milk influences the plasma appearance of metabolites, especially lipids, that may contribute to early postnatal life development in pigs.

Abstract
OBJECTIVE To evaluate plasma taurine concentrations (PTC), whole blood taurine concentrations (WBTC), and echocardiographic findings in dogs fed 1 of 3 protein-restricted diets that varied in fat and L-carnitine content. ANIMALS 17 healthy Beagles. DESIGN Baseline PTC and WBTC were determined, and echocardiography was performed in all dogs consuming a maintenance diet. Dogs were then fed 1 of 3 protein-restricted diets for 48 months: a low-fat (LF) diet, a high-fat and L-carnitine supplemented (HF + C) diet, or a high-fat (HF) diet. All diets contained methionine and cystine concentrations at or above recommended Association of American Feed Control Officials (AAFCO) minimum requirements. Echocardiographic findings, PTC, and WBTC were evaluated every 6 months. RESULTS The PTC and WBTC were not significantly different among the 3 groups after 12 months. All groups had significant decreases in WBTC from baseline concentrations, and the HF group also had a significant decrease in PTC. One dog with PT and WBT deficiency developed dilated cardiomyopathy (DCM). Taurine supplementation resulted in significant improvement in cardiac function. Another dog with decreased WBTC developed changes compatible with early DCM. CONCLUSIONS AND CLINICAL RELEVANCE Results revealed that dogs fed protein-restricted diets can develop decreased taurine concentrations; therefore, protein-restricted diets should be supplemented with taurine. Dietary methionine and cystine concentrations at or above AAFCO recommended minimum requirements did not prevent decreased taurine concentrations. The possibility exists that AAFCO recommended minimum requirements are not adequate for dogs consuming protein-restricted diets. Our results also revealed that, similar to cats, dogs can develop DCM secondary to taurine deficiency, and taurine supplementation can result in substantial improvement in cardiac function.

Abstract
Nutritional intake in the patient with hepatobiliary disease provides the cornerstone of balanced medical care. Optimal recommendations require consideration of general nutritional principles, special species requirements and contemporary needs uniquely related to the patient's medical problem. Although general recommendations follow well-established guidelines developed to meet metabolic requirements for normal health, there is little information regarding altered requirements in animals that are ill. Consequently, recommendations for animals have been derived empirically from studies completed in humans, most work having been done in patients with end stage cirrhosis or liver failure complicated by hepatic encephalopathy. This is problematic because most veterinary patients with liver disease are not in hepatic failure and do not suffer from hepatic encephalopathy. Iatrogenic malnutrition can develop in patients when protein-restricted diets are inappropriately recommended. Insufficient energy intake and negative nitrogen balance can complicate a patient's condition, impairing tissue regeneration and recovery from disease. This paper reviews strategies that can be used to individualize nutritional management in small companion animals with hepatobiliary disease. Consideration is given to both the known and controversial issues regarding energy requirements, dietary energy distribution, vitamin and micronutrient supplementation, the special requirements of the cat with hepatic lipidosis, as well as strategies effective for palliation of hepatic encephalopathy.

Abstract
Taurine kinetics in cats was investigated using a bolus dose of [15N]- and [1,2-13C2]taurine. The comparison of [15N]- and [13C2]taurine kinetics permitted an evaluation of the extent of taurine transamination. A methodology which involves N-pentafluorobenzoyl di-n-butylamine derivatization of taurine and GC/MS measurements of the 15N- and 13C-enrichments in cat urine was developed. Accuracy of the measurements was determined using pure standard compounds and the results showed that [13C2]taurine does not interfere with [15N]taurine. In cats, no differences were observed between both tracers. Therefore, we conclude that taurine reversible transamination does not occur at a significant level in cats.

Abstract
Fourteen American Cocker Spaniels (ACS) with dilated cardiomyopathy (DCM) were studied to determine if individuals of this breed with DCM are systemically taurine- or carnitine-deficient and to determine if they are responsive to taurine and carnitine supplementation. American Cocker Spaniels with DCM were identified using echocardiography, and plasma was analyzed for taurine and carnitine concentrations. Each dog was randomly assigned to receive either taurine and carnitine supplementation or placebos. Echocardiograms and clinical examinations were repeated monthly for 4 months. During this period, the investigators and owners were blinded with respect to the treatment being administered. Each dog was weaned off its cardiovascular drugs (furosemide, digoxin, and an angiotensin converting enzyme inhibitor) if an echocardiographic response was identified. At the 4-month time period, each investigator was asked to decide whether he or she thought his or her patient was receiving placebo or taurine/carnitine, based on presence or absence of clinical and echocardiographic improvement. Unblinding then occurred, and dogs receiving placebos were switched to taurine and carnitine supplementation and followed monthly for 4 additional months. All dogs were reexamined 6 months after starting supplementation; survival time and cause of death were recorded for each dog. Data from 3 dogs were not included because of multiple protocol violations. Each dog had a plasma taurine concentration < 50 nmol/mL (mean +/- SD for the group 15 +/- 17 nmol/ mL) at baseline; normal range, 50-180 nmol/mL. The plasma taurine concentration did not exceed 50 nmol/mL at any time in the dogs receiving placebos (n = 5), but increased to 357 +/- 157 nmol/mL (range 140-621 nmol/mL) during taurine and carnitine supplementation (n = 11). Plasma carnitine concentration was within, only slightly below, or slightly above reported limits of normality at baseline (29 +/- 15 mumol/L); did not change during placebo administration; and increased significantly during supplementation (349 +/- 119 mumol/L; n = 11). Echocardiographic variables did not change during placebo administration. During supplementation, left ventricular end-diastolic and end-systolic diameters, and mitral valve E point-to-septal separation decreased significantly in both groups. Shortening fraction increased significantly but not into the normal range. Echocardiographic variables remained improved at 6 months. All dogs were successfully weaned off furosemide, an angiotensin converting enzyme inhibitor, and digoxin once an echocardiographic response was identified. Nine of the dogs have died since the onset of the study in 1992. One dog died of recurrence of DCM and heart failure 31 months after starting supplementation; six dogs died of noncardiac causes. Two dogs developed degenerative mitral valve disease and died of complications of this disease. Dogs less than 10 years of age lived for 46 +/- 11 months, whereas dogs older than 10 years of age lived for 14 +/- 7 months. Two of the 11 dogs were alive at the time of publication, having survived for 3.5 and 4.5 years, respectively. We conclude that ACS with DCM are taurine-deficient and are responsive to taurine and carnitine supplementation. Whereas myocardial function did not return to normal in most dogs, it did improve enough to allow discontinuation of cardiovascular drug therapy and to maintain a normal quality of life for months to years.

Abstract
The effect of dietary protein source (soybean vs. casein) and taurine status on kinetics of [24-14C] and [taurine-2-3H]taurocholic acid was determined by isotope dilution in 10 adult male cats (six taurine-replete and four taurine-depleted). Taurine-replete cats were fed 1500 mg taurine/kg purified diets containing either 435 g/kg casein (1500 Cas) or soybean protein (1500 Soy) in a crossover design. Taurine-depleted cats were fed the soybean protein diet with no taurine (0 Soy). Specific activity of [14C]- and [3H]taurocholic acid in bile was determined for 6 d following a pulse dose of dual-labeled taurocholic acid. Taurocholic acid pool size was significantly greater in cats when fed the 1500 Soy diet than when fed the 1500 Cas or than in cats fed the 0 Soy diet. Total entry rate, irreversible loss rate and recycling rate of [taurine-2-3H]taurocholic acid and the irreversible loss rate of [24-14C]taurocholic acid tended to be greater in cats when fed the 1500 Soy than the 1500 Cas diet. Irreversible loss rates of taurocholic acid in taurine-replete cats fed the 1500 Soy diet were significantly greater than in taurine-depleted cats, 356 vs. 120 mumol/d [24-14C]taurocholic acid and 445 vs. 56 mumol/d [taurine-2-3H]taurocholic acid. The fraction of taurocholic acid was greater, and the fraction of taurochenodeoxycholic and taurodeoxycholic acids lower in cats when fed the 1500 Soy than when fed the 1500 Cas diet. Taurine-depleted cats had less taurocholic, taurochenodeoxycholic, and taurodeoxycholic acids and greater glycocholic and cholic acids than taurine-replete cats fed the 1500 Soy diet. This study demonstrates that both dietary protein source and taurine status affect taurocholic acid kinetics and bile acid composition in cats.

Abstract
M-mode echocardiography was completed and plasma taurine concentrations were determined in 79 healthy cats and 77 cats with dilated cardiomyopathy (DCM). In healthy cats, a relationship was not observed between plasma taurine concentrations and any M-mode echocardiographic measurement. End-systolic and end-diastolic cardiac chamber dimensions were larger; wall thickness measures were smaller; and calculations of fractional shortening were less in cats with DCM than in healthy cats. Plasma taurine concentrations less than 30 nmol/mL were detected in 7/79 healthy cats and in 52/77 cats with DCM. Of the 52 cats with DCM and an initial plasma taurine concentration less than 30 nmol/mL, 23 died or were euthanized during the first post-treatment week, 7 were lost to further study, and 22 improved after taurine supplementation. Of the 25 cats with DCM and an initial plasma taurine concentration greater than or equal to 30 nmol/mL, 9 died or were euthanatized during the first post-treatment week, and 9 were lost to further study. Two cats did not improve, of which one died and one was euthanatized 4 to 8 weeks after initiation of taurine supplementation. Five cats with a plasma taurine concentration greater than or equal to 30 nmol/mL improved after taurine supplementation. Myocardial function subsequently deteriorated in three of these cats. Two of the three cats had signs of congestive heart failure redevelop.

Abstract
Thousands of pet cats die each year with dilated cardiomyopathy, the cause of which is unknown. Although taurine is present in millimolar concentrations in the myocardium of all mammals, taurine depletion has not previously been associated with a decrease in myocardial function in any species. In this study, low plasma taurine concentrations associated with echocardiographic evidence of myocardial failure were observed in 21 cats fed commercial cat foods and in 2 of 11 cats fed a purified diet containing marginally low concentrations of taurine for 4 years. Oral supplementation of taurine resulted in increased plasma taurine concentrations and was associated with normalization of left ventricular function in both groups of cats. Since myocardial concentrations of taurine are directly related to plasma concentrations and low plasma concentrations were found to be associated with myocardial failure in cats, a direct link between decreased taurine concentration in the myocardium and decreased myocardial mechanical function is proposed.
