Norfolk Terrier

An appropriate energy intake for healthy growth can reduce the risk of obesity and co-morbidities, such as orthopaedic diseases. The 2006 National Research Council (NRC) universal equation calculates the energy requirement of growing dogs based on predicted adult body weight, but evidence suggests a revision may be required. This study investigates the energy requirements of seventeen Norfolk terrier puppies over their first year (10 to 52 weeks). Puppies were individually fed complete and balanced diets in amounts to maintain an optimal body condition score (BCS), recording intake daily and body weight and BCS weekly. To monitor health a veterinary examination, haematology and plasma biochemistry and serum measures of bone turnover were undertaken every 12 weeks. Skeletal development was assessed using dual-energy X-ray absorptiometry (26 and 52 weeks). Puppies were clinically healthy with normal skeletal development and healthy growth throughout. The energy intake to achieve this was significantly lower than that predicted by the NRC (2006) equation at all time points, with largest mean difference of 285 kJ/kg0·75 per day at 10 weeks. If fed according to the NRC 2006 equation, dogs would have been in positive energy balance, possibly leading to obesity. These data support a revision to the NRC (2006) equation.

AbstractThe 2006 National Research Council (NRC) equation calculating puppy energy requirements does not account for reported breed differences in growth pattern. Energy requirements of toy breed puppies are unknown and it is unclear whether feeding guidelines should differ between breeds. Energy requirements of Yorkshire terrier (YT) puppies were observed over their first year of life and compared with those predicted by the NRC and those previously observed in large (Labrador retriever) and medium (miniature Schnauzer; MS) breed puppies. Twenty-two puppies (from eight litters) were offered complete and balanced diets to maintain ideal body condition score (BCS). Energy intake, body weight and BCS were recorded from 10 to 52 weeks of age. Every 12 weeks, health was monitored by veterinary examination, routine haematology and plasma biochemistry. Puppies remained clinically healthy with normal skeletal development throughout. After analysis by linear mixed models it was observed that the NRC equation overestimates YT energy requirements between 10 and 20 weeks of age by up to 324·3 (95 % CI 390·4, 258·2) kJ/kg0·75. Energy intake was lower (P < 0·05) in YT than Labradors until 29 weeks by up to 376·6 (95 % CI 477·4, 275·3) kJ/kg0·75 and lower than MS between 16 and 25 weeks by up to 216·3 (95 % CI 313·0, 119·7) kJ/kg0·75 (P < 0·05). Data indicate differences in toy, medium and large breed energy requirements for growth. The NRC equation for puppy energy requirements overestimated the requirements of this YT population, suggesting the need for breed-specific feeding guides for growth to avoid overfeeding.

Obesity is a common problem in cats. In the experimental cat family of the institute of animal nutrition besides a “normal” lean phenotype, cats with predisposition to an overweight phenotype are present. To investigate energy requirements and food intake behaviour of intact male cats of different phenotypes, six “normal” lean cats (GL) and six cats disposed to overweight (GO) were used. At the beginning of the experiment, all cats had an ideal body condition score of 5. To reach this the GO cats had to pass a weight-loss program. Energy requirements of the cats were determined using respiration chambers, whereas the amount and frequency of food intake was measured with a feeding station recording the data automatically. Energy requirement at weight constancy of the GO cats was even on fat-free mass (FFM) significantly (P=0.02) lower (162.6 kJ/kg FFM/d) than that of the “normal” lean cats (246 kJ/kg FFM/d). The GO cats also showed a higher food intake34.5±1.5 g dry matter/kg body weight0.67compared to the GL cats (24.0±2.1 g dry matter/kg body weight0.67)(P=0.001). In conclusion quantifiable differences in food intake and behaviour in cats predisposed to overweight compared to “normal” lean cats were found.

AbstractObjectiveTo test equations for calculating infants’ energy requirements as a simple and reliable instrument for estimating the amount of breast milk consumed in epidemiological studies where test-weighing is not possible.DesignInfants’ energy requirements were calculated using three different equations based on reference data and compared with actual energy intakes assessed using the 3 d weighed dietary records of breast-fed infants from the DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD) Study.SettingA sub-sample of 323 infants from the German DONALD Study who were predominantly breast-fed for at least the first four months of life, and who had 3 d weighed dietary records and repeated body weight measurements within the first year of life.SubjectsHealthy, term infants breast-fed for at least 4 months, 0–12 months of age.ResultsThe overall differences between measured energy intake and calculated energy requirements were quite small, never more than 10 % of total energy intake, and smaller than the mean variance of energy intake between the three days of recording. The equation of best fit incorporated body weight and recent growth, while the worst fit was found for the equation not considering body weight.ConclusionsBreast milk consumption in fully and partially breast-fed infants can be reasonably quantified by calculating the infants’ individual energy requirements via simple equations. This provides a feasible approach for estimating infant energy intake in epidemiological studies where test-weighing of breast milk is not possible.

AbstractNeutering is a risk factor for obesity in companion animals. In a study to determine the total energy requirements of kittens (15–52 weeks) the impact of neutering and age when neutered on intake and body weight (BW) was investigated. Females (n 14), neutered when 19 (early neuter; EN) or 31 (conventional neuter; CN) weeks old (n 7/group), were individually fed to maintain an ideal body condition score (BCS). EN kittens gained weight gradually whilst CN kittens’ BW gain slowed from week 24, weighing less than EN kittens from week 30 with a reduced energy intake (kcal/kg BW0·67) in weeks 24–32 (P < 0·05). Following neutering, CN cats’ BW and energy intake increased rapidly (energy intake CN > EN in weeks 36–40). Although EN required earlier diet restriction, acute hyperphagia and increased rate of BW gain following neutering were not observed. Earlier neutering may aid healthy weight management through growth when regulating intake to maintain an ideal BCS.

Objective: This study was conducted to determine the energy intake of adult residents of district 13 of Tehran and compare the results with their energy requirements. Design: In this cross-sectional study, 403 subjects were selected by random sampling, including 145 men and 151 women aged 25–50 years and 57 men and 50 women over 50 years old in the framework of Tehran Lipid and Glucose Study (TLGS). Measurements: Height, body weight, waist and hip circumferences were measured, and the body mass index (BMI) and waist-to-hip ratio (WHR) were calculated. Mean energy requirements for each sex-age group were estimated by multiplying specific coefficients (allocated to each group) by body weight and resting energy expenditure (REE), and the results of both methods were compared with mean energy values recommended by Food and Agriculture Organization (FAO) /World Health Organization (WHO) and the U.S. recommended dietary allowance (RDA). Dietary assessment was performed by 48-hour diet recall. A ratio of energy intake to basal metabolic rate lower than 1.27 was considered as under-reporting. Physical activity was evaluated by standard questionnaire of the Lipid Research Clinics (LRC). Results: Women were significantly more overweight and obese than men (p < 0.001) and older women were more obese than younger ones (p < 0.05). Only one-third of the study population had adequate physical activity. Women had significantly lower physical activity than men (p < 0.01). Energy requirements for both age and sex groups were lower than recommended daily allowances for energy: men 25–50; 2576 vs. 2900; men > 50: 2155 vs. 2300; women 20–50: 2045 vs. 2200 and women > 50: 1817 vs. 1900 kilocalories (kcal). Reported energy intake of men was higher and that of women was lower than the RDA. Forty percent of women and 14% of men under-reported their energy intake. Conclusion: The energy requirement of the average Tehranian is lower than daily allowances; conditions of obesity and overweight are more prevalent in women. There is high frequency of under-reporting of energy intake in women. Lifestyle modifications to improve dietary habits and to increase physical activity are recommended to decrease overweight and obesity in urban population of Tehran.

The apparent digestible energy requirement of the adult female mink for maintenance purposes has been determined and found to be in close agreement with that suggested by the Committee on Animal Nutrition of the United States National Research Council. The energy intake data recorded are best described by the equation, intake = 0.226 weight + 14, under conditions of body weight stasis with the animals housed in ranch-type cages. Cage size had a definite influence on the requirement for energy. The mink appears to have a higher maintenance requirement than would be predictable from work with other species.

Twelve adult (10 months old) castrated Korean black goats, with an average initial body weight of 24.98 ± 3.7 kg, were used in this experiment to determine their maintenance energy requirements. Dry matter intakes (g/d, p = 0.945) were not affected by energy levels, but metabolic energy intake (kcal/d, p < 0.002) and average daily gain (g/d, p < 0.001) were significantly increased at higher energy levels. Nutrient digestibility was similar in the treatments, but crude fat digestibility increased with the addition of protective fat powder (p = 0.001). The energy required for fattening the castrated Korean black goats was estimated using the correlation between metabolic energy intake per dietary body weight and average daily gain per dietary body weight. The Y-axis intercept value was calculated to be 108.76 kcal/kg BW0.75 (p < 0.05, r2 = 0.6036), which was the metabolic energy requirement for maintaining the lives of the fattening Korean black goats. The estimated energy requirements of the black goat can improve specification techniques, such as the energy level and the amount of feed supply required for domestic black goats.

Ad Libitum

Sugar-sweetened beverage (sugar-SB) consumption is associated with body weight gain. We investigated whether the changes of (Δ) circulating leptin contribute to weight gain and ad libitum food intake in young adults consuming sugar-SB for two weeks. In a parallel, double-blinded, intervention study, participants (n = 131; BMI 18–35 kg/m2; 18–40 years) consumed three beverages/day containing aspartame or 25% energy requirement as glucose, fructose, high fructose corn syrup (HFCS) or sucrose (n = 23–28/group). Body weight, ad libitum food intake and 24-h leptin area under the curve (AUC) were assessed at Week 0 and at the end of Week 2. The Δbody weight was not different among groups (p = 0.092), but the increases in subjects consuming HFCS- (p = 0.0008) and glucose-SB (p = 0.018) were significant compared with Week 0. Subjects consuming sucrose- (+14%, p < 0.0015), fructose- (+9%, p = 0.015) and HFCS-SB (+8%, p = 0.017) increased energy intake during the ad libitum food intake trial compared with subjects consuming aspartame-SB (−4%, p = 0.0037, effect of SB). Fructose-SB decreased (−14 ng/mL × 24 h, p = 0.0006) and sucrose-SB increased (+25 ng/mL × 24 h, p = 0.025 vs. Week 0; p = 0.0008 vs. fructose-SB) 24-h leptin AUC. The Δad libitum food intake and Δbody weight were not influenced by circulating leptin in young adults consuming sugar-SB for 2 weeks. Studies are needed to determine the mechanisms mediating increased energy intake in subjects consuming sugar-SB.

Background: Population exposed to chronic undernutrition in early life seems to be more susceptible to obesity in adulthood due to the development of mechanisms that improve the efficiency of energy use. Therefore, these individuals have relatively reduced energy requirements (thrifty phenotype). Objective: To investigate, among women living on severe socioeconomic vulnerability, whether short stature, a marker for undernutrition in early life, is associated with excess body weight but not with a high energy intake. Methods: This cross-sectional study, carried out between July and November 2008, evaluated 1308 women from all (N = 39) Quilombola communities of Alagoas. Adequacy of energy intake was estimated by the ratio between energetic ingestion and the estimated energy requirement (EER). Results: The prevalence of short stature (≤ 154.8 cm) was 43.0% and 52.4% had excess body weight (body mass index ≥ 25 kg/m2), being that 33.1% were overweight and 19.3% obese. Excess body weight was higher among women with short stature (56.6% vs 49.2%; P = .008), even after adjusting for age, energy intake, and per capita income (prevalence ratio = 1.16; 95% confidence interval = 1.04; 1.28). The ratio of energy intake/EER was independent of women’s stature. Conclusion: Excess body weight among Quilombola women represents a serious health problem. Short stature was significantly associated with excess body weight but not with a high energy intake. “Thrifty phenotype” may be one of the plausible explanations for this finding.
