Abstract Obesity reduces the quality and length of life of companion animals. Spaying increases risk, but dietary modification may attenuate obesity and related co-morbidities. The objective of this study was to determine the effects of specially formulated diets on apparent total tract macronutrient digestibility (ATTD) and fecal metabolites of female dogs after spay surgery. All procedures were approved by the University of Illinois Institutional Animal Care and Use Committee prior to experimentation. Twenty-four dogs were spayed and randomly allotted to three experimental diets: 1) moderate-protein, moderate-fiber diet (control; COSP), 2) high-protein, high-fiber diet (HP-HF), or 3) high-protein, high-fiber diet plus omega-3 fats (HP-HF-O). Four dogs were sham-operated and fed the control diet (COSH). Dogs were fed to maintain BW for 12 weeks after spay, then allowed to consume twice that amount for another 12 weeks. Change from baseline data were analyzed statistically, with P < 0.05 being significantly different. Food intake in dogs fed HP-HF or HP-HF-O was greater than COSH dogs, but COSP dogs were intermediate. Fat and organic matter digestibilities were lower in dogs fed HP-HF or HP-HF-O compared with COSH and COSP dogs. Fecal dry matter percentage and volume increases were greater in HP-HF and HP-HF-O dogs than COSH and COSP dogs. HP-HF and HP-HF-O dogs had higher fecal acetate than COSH or COSP dogs. Fecal butyrate tended to be greater (P = 0.08) in HP-HF dogs than COSH dogs. COSH and HP-HF-O dogs had lower fecal valerate than COSP dogs, while fecal ammonia tended to be higher (P = 0.05) in HP-HF-O than COSP and HP-HF dogs. Fecal total short-chain fatty acid (SCFA) increases in HP-HF-O dogs were higher than COSH dogs. Our results indicate that a high-protein, high-fiber diet can reduce energy content by reducing fat digestibility without affecting protein digestibility, modulate fecal SCFA concentrations, and decrease fecal branched-chain fatty acid.

Optimal intestinal development in gilts is a prerequisite for a better farrowing and a higher feed intake in lactation, and these are important facets in improving animal welfare for sows in a high-performance situation. The present study aimed to evaluate the effects of a fiber-rich diet on these topics. Studies with 20 male Topigs castrates and a performance study with 38 female siblings were conducted. Pigs in both of the groups were offered either a control diet (CG) or a high fiber diet (FG) during the second half of the rearing phase (~97 kg BW) until 7 days a.p. At the time of the insemination of the gilts (body weight >170 kg), the castrates were slaughtered and the morphological parameters of the gastrointestinal tract were taken. In the performance study, the feed intake as well as the number and weight of the live and stillborn piglets and the weaning weight of the litters were recorded. The results indicated that the high fiber diet with a greater swelling capacity was beneficial to the development of the gastrointestinal tract (stomach weight CG = 714 g, FG = 812 g, p = 0.007), increased the litter weight (CG =15.9 kg, FG = 20.6 kg, p = 0.045) and resulted in a higher feed intake during lactation overall (CG = 196 kg, FG = 211 kg, p = 0.035).

Abstract Canine obesity can be managed by dietary energy restriction using a specifically formulated weight loss diet. The objective of this study was to determine the effects of weight loss on body composition, voluntary physical activity, and blood metabolites of overweight dogs while being fed a high-protein, high-fiber diet. All procedures were approved by the University of Illinois Institutional Animal Care and Use Committee prior to experimentation. Twelve overweight adult spayed female dogs (BW: 15.3±2.1 kg, BCS: 8.1±0.6) were fed a high-protein (CP: 42.0% DMB), high-fiber (TDF: 22.0% DMB) diet during a 5-wk baseline phase (wk 0) to identify food intake needed to maintain BW. A 24-wk weight loss phase followed. After wk 0, food was initially provided at 80% the amount needed to maintain BW and then adjusted weekly with a goal of 1.5–2% weight loss per wk. Data were analyzed statistically overtime using SAS 9.4. After 24 wk, dogs lost 31.2% of initial BW (P < 0.0001), with 1.4±0.7% weight loss per wk. BCS decreased by 2.8 units (P < 0.0001). During weight loss, dogs consumed an average of 457.5±61.4 kcal/d, with energy intake being reduced by a total of 43.8% by wk 24 compared to baseline. Lean muscle mass, fat mass, and fat percentage were reduced (P < 0.0001) by 1.3 kg, 3.1 kg, and 11.7% respectively. Serum triglycerides, alkaline phosphatase, white blood cell counts, and neutrophils were decreased (P < 0.0001), but serum bilirubin, creatinine, and blood urea nitrogen were increased (P < 0.01) over time. Average daily physical activity changed over time, but was not greatly different due to weight loss. Our results suggest that a high-protein, high-fiber diet promotes fat mass loss, minimizes lean muscle mass loss, and reduces inflammatory marker and triglyceride concentrations in overweight dogs. Therefore, it is a suitable nutritional solution for weight loss programs in dogs.

Abstract. The effects of breed (Hubbard and Anak), sex and diet (two levels of protein (high or low) with two levels of crude fiber (low or high) at each level of protein) on carcass composition and distribution of tissues over the carcass were studied. Carcass composition and ratios of muscle: bone, muscle: fat and meat: bone in the carcass did not differ significantly between breed groups. Male carcasses had more muscle, more bone, more fat-free carcass, higher ratios of muscle: bone, muscle: fat but less fat, less meat and lower meat: bone ratio than female carcasses. Carcasses of chicks fed high protein (with either low or high fiber) diet had more muscle than carcasses of chicks fed low protein (with either low or high fiber) diet. Carcasses of chicks fed high fiber (with either low or high protein) diet had more bone but less meat than carcasses of chicks fed low fiber (with either low or high protein) diet. Increasing both protein and fiber in the diet resulted in lowering carcass fat, consequently raising muscle: fat ratio. Breed and sex did not influence the distribution of muscle and meat throughout the carcass parts. Breed differences in fat weight distribution were not significant. Anak had significantly higher proportions of bone in wing and neck than Hubbard did. The proportion of total carcass muscle in breast, drumstick, wing were not significantly affected by diet. Carcasses of chicks fed high fiber (with either low or high protein) diet had higher proportion of total meat in thigh and neck than carcasses from chicks fed low fiber (with either low or high protein) diet. Diet had no significant effect on bone weight distribution. Increasing crude fiber in diets resulted in lowering proportion of total fat in breast, thigh but increasing proportion of total fat in drumstick and wing. Breed x sex, breed x diet and sex x diet interactions did not significantly influence most of carcass traits indicating that the factors under consideration act independently of each other's. Significant sex x diet interactions was found for carcass fat and boneless carcass relative to live body weight: the sexual dimorphism in low protein diet is more pronounced than in high protein diets.

Cecropin A

We hypothesised that the dietary addition of the bioactive antimicrobial protein lactoferrin (LF) and peptides melittin (MT) or cecropin A (CR) at a dosage of 100 mg/kg to the diet of Wistar rats would result in strong modulatory effects on faecal microbial enzymatic activity, short-chain fatty acid and ammonia concentrations. To date, the changes in bacterial extracellular and intracellular enzymatic activities upon addition of dietary AMPs have not yet been studied. This experiment lasted 15 days; during the first 5 day period, the rats were fed the control diet (S) and diets supplemented with LF, MT or CR. On days 6–15, all rats were fed the control S diet. The faecal fermentation processes were substantially stopped after two days of treatment, on average, in all rats receiving LF and two AMPs. The deepest suppression effect was observed on the last day of treatment (day 5) and persisted through days 5–8. The highest decreases in faecal bacterial β-glucosidase and β-glucuronidase activities as well as in SCFA and ammonia concentrations were observed in the rats fed the CR diet. Only in the CR animals did the mechanism of suppressed microbial fermentation involve diminished enzyme release from bacterial cells to the digesta.
