Forty Large White barrows were used to determine whether the effects of dietary fat source (tallow or soy oil at 5% of the diet) on lipogenesis and fatty acid profile of porcine adipose and lean tissue were dependent on dietary digestible energy density (8.8 vs 14.0 MJ DE/kg). Barrows were allocated to one of four groups and offered a fixed amount of feed (170 g x BW0.569/d) from 27 to 105 kg B...

Forages and crop residues are inexpensive and easily available feedstuffs for feeding grasscutters in captivity. These feedstuffs are nutritionally poor, not balanced for optimum performance and, therefore, required supplementation. Protein requirement of growing grasscutters was determined using thirty two 10-weeks old male grasscutters of equal weights. The grasscutters were separated into fo...

U N D E R conditions of ad libitum feeding, performance of swine is determined mainly by the voluntary feed consumption and the adequacy of nutrient levels in the diet. Recent emphasis has been on the establishment of optimum relationships between energy concentration and the levels of other nutrients in the diet. The relationship of source and concentration of dietary energy to level and quali...

BACKGROUND It has been reported that walnuts reduce serum cholesterol levels in normal young men. OBJECTIVE To assess the acceptability of walnuts and their effects on serum lipid levels and low-density lipoprotein (LDL) oxidizability in free-living hypercholesterolemic persons. DESIGN Randomized, crossover feeding trial. SETTING Lipid clinic at a university hospital. PATIENTS 55 men an...

A feeding trial of three dietary protein (DP) (25, 35 and 45%) and four dietary lipid (DL) levels (3, 6, 9 and 12%) with different dietary energy to protein (E/P) ratios (from 5.93 to 13.84 kcal/g protein) was conducted to investigate the proper dietary E/P ratio for juvenile grass carp. After acclimation of 2 weeks by a lipid-free diet, fish were reared for 10 weeks in a water recirculation sy...

The main objective of this study was to elucidate the effect of short- term exposure of Japanese quail eggs to acute high incubation temperature on embryonic development and on the ability of post- hatched chicks to cope with subsequent heat stress conditions during the growing period. A total of 998 Japanese quail eggs were divided into two groups, the first group (470 eggs) was maintained at ...

S • A3 expansion of C4 grasses. Mesowear analysis and mandibular measurements were recorded on a suite of common Siwalik ungulate taxa including bovids, tragulids, giraffids, and equids dated before and after 8 Ma. Results are compared to published microwear and stable carbon isotope data. Preliminary data suggest that the dietary reconstruction obtained for some taxa as well as the observation...

The existence of a set-point for homeostatic control of human body weight is uncertain. To investigate its existence, technically difficult determinations of energy expenditure must be performed: this has resulted in contradictory reports. The present study was performed with new methods in two stages (77 and 133 d respectively). Two healthy male subjects with rigorously controlled physical act...
