Regulation of body weight : effects of pharmacological and environmental interventions on energy budget

Zhang, Lina January 2011 (has links)
Pharmacological blockade of the endocannabinoid system via rimonabant (SR141716) induced a sustained reduction in weight and fatness. Rimonabant-treated mice exhibited reduced metabolizable energy intake and increased daily energy expenditure on days 4-6 of treatment. However, these on the energy budget had disappeared by day 22-24. Rimonabant treatment increased daily physical activity levels throughout the study. These data suggested that rimonabant caused a negative energy balance by acting on both energy intake and expenditure. Melanin-concentrating receptor 1 (MCHR1) antagonism via GW803430 produced similar effects on energy  budget. However, only physical activity during the dark phase was increased by GW803430 treatment. MCHR1 antagonism produced a persistent anti-obesity effect and the initiation of weight loss resulted from a decrease in energy intake and an increase in active energy expenditure. With respect to environmental interventions, non-genetic individual variability in weightgain when fed a high fat diet (HFD) was investigated. I found that weight gain induced by HFD was associated positively with fat mass and fast free mass and negatively with physical activity prior to HFD exposure. Furthermore, fat mass and fat free mass were influenced by lactation litter size via weaning weight and post-weaning growth rate. Finally I used intermittent starvation to test whether the risk of starvation determines the lower intervention point as suggested by the dual intervention pointmodel. Overall, mice exhibited different behavioural and physiological responses to intermittent starvation dependent of the duration of treatment. This work contributes to a better understanding of the regulation of energy balance and provide useful insights for the prevention and treatment of obesity.

Nutritional Modulations of Piglet Growth and Survival

Rezaei, Reza 2010 December 1900 (has links)
This thesis research was conducted to test the hypothesis that the survival and growth of both neonatal and postweaning piglets can be improved by nutritional modulations. Two experiments were carried out to 1) evaluate effects of birth weight on mortality, growth performance, and efficiency of sow-reared piglets; and 2) determine the effects of a phytochemical (Yucca schidigera) on growth performance of postweaning pigs. In the first experiment, piglets (n=160) from 18 multiparous sows (Landrace X Large White) were used. Body weight of all piglets were recorded immediately after birth, d 7, d 14, d 21 and d 35 of their age. Individual milk consumption of piglets was estimated using the weigh-suckle-weigh method. Average daily gain and mortality were recorded. To analyze the effects of birth weight on future BW and growth, piglets were classified based on their birth weight into four categories of A: 0.7-1.09 kg, B: 1.10-1.49 kg, C: 1.50-1.89 kg and D: >1.90. Data were statistically analyzed using one-way ANOVA. Results indicated that low birth weight of pigs not only increased (P < 0.05) their incidence of mortality but also negatively impacted (P < 0.05) their whole-body growth. Interestingly, surviving low-birth-weight piglets had a higher (P < 0.05) rate of efficiency to utilize milk nutrients for growth than larger littermates. In the second experiment, two 21-day trials using 21-d-old postweaning piglets (n=111) were performed (d 21 to 42 of age). In the first trial, pigs were assigned to one of the three groups fed diets supplemented with 0 (control), 120 ppm or 180 ppm of Yucca powder (BIOPOWDER). The second trial was conducted as the first trial except that the basal diet contained 0.2 percent L-citrulline (an effective precursor of arginine). Body weight, average daily gain and feed intake of all pigs were measured weekly in both trials. At the last day of experiment, 2 h after the last meal, jugular blood samples were taken from all pigs in both trials for amino acid analysis. One-way ANOVA was used to statistically analyze the data. When the basal diet did not contain citrulline, dietary supplementation with BIOPOWDER did not affect (P > 0.05) any of the measured variables related to growth performance. However, supplementing an appropriate dose of this yucca extract (120 ppm) to a citrulline-fortified diet increased growth performance and feed efficiency in these animals. Adequate availability of arginine is required for BIOPOWDER to exert its anabolic effect on piglet growth and its regulatory action on improving the efficiency of nutrient utilization in young pigs. These findings have important implications for nutritionally modulating the growth of neonatal pigs and, therefore, the swine industry worldwide.

Enhancement of Growth Performance and Bone Mineralization in Market Broilers through Dietary Enzymes

Coppedge, Jacob Ryan 2010 December 1900 (has links)
Four research experiments were conducted to evaluate the influence of dietary enzyme inclusion (phytase and NSPase) on broiler performance parameters, processing yields, and bone mineralization. In Experiment 1, a 35-day grow out trial was conducted to investigate the effect of three commercially available phytase enzymes on growth performance and bone mineralization in phosphorus deficient corn/soy based diets. Increasing the level of available phosphorus (aP) in the control diets resulted in improved bird performance and bone ash data. The presence of dietary phytase in phosphorus deficient diets resulted in improvements in growth parameters and bone mineralization. Regression analysis confirmed that phytase supplementation can potentially increase the bioavailability of phosphorus in broiler diets up to 0.15 to 0.20 percent, however, the responses varied according to the enzyme used and inclusion level. In Experiment 2, a 42-day grow out trial was conducted to analyze the effects of NSPase inclusion on broiler performance and processing parameters when supplemented in diets with varying protein and energy concentrations. Reduced protein and energy levels reduced bird performance throughout the trial. The inclusion of both NSPase enzymes resulted in improvements in feed conversion throughout the starter and grower periods (day 26 of age). The results from this trial showed that NSPase inclusion can improve broiler performance and processing parameters. In Experiments 3 and 4, a battery trial and a floor trial were conducted to determine the effects of phytase and NSPase enzyme co-administration on growth and bone ash in low phosphorus diets. Increasing the level of available phosphorus resulted in increased bird performance and bone ash. The inclusion of phytase enhanced bird performance and bone mineralization. NSPase inclusion in diets containing low levels of phytase had improvements in bird performance during early stages of growth. The enhanced effects associated with dual administration of phytase and NSPase were not observed in a full grow out trial during later stages of growth. These four experiments indicate that phytase and NSPase enzyme inclusion in broiler diets have the ability to enhance bird performance, processing yield, and bone mineralization.
