We compared fat distribution and lipoprotein lipase (LPL) activity in steers differing in adaptability to the subtropics. Steers were fed a grain diet (3.13 Mcal ME/kg DM) at limited (150 kcal ME x kg[-.75] x d[-1]; .23 kg ADG) or ad libitum levels for 140 d, then slaughtered. Sixteen British- (8 Angus, 8 Hereford; S), 16 Boran- (R), 16 Brahman- (B), and 16 Tuli- (T) cross steers from MARC III ...
BACKGROUND Intermittent severe energy restriction is popular for weight management. To investigate whether intermittent moderate energy restriction may improve this approach by enhancing weight loss efficiency, we conducted a study in mice, where energy intake can be controlled. METHODS Male C57/Bl6 mice that had been rendered obese by an ad libitum diet high in fat and sugar for 22 weeks wer...
The effect of forage and breed of lambs on the fatty acid profile of intramuscular fat in m. longissimus lumborum (LL) and depot fat (SCF) above this muscle was investigated. The study was carried out in two replications on 36 Koluda sheep (KS) and Ile de France×KS (IF×KS) ram-lambs fattened intensively to 32–37 kg of body weight. Lambs were fed ad libitum the same concentrate mixture and diffe...
Ninety-six Yorkshire males at 28 d of age were placed on a pre-test feeding regimen (22% CP) of either ad libitum (A) access to feed or a restricted (R, 85% of A) diet. All pigs were housed in groups of four until approximately 30 kg body weight. The boars were then placed under test and assigned to a group pen (GP) containing eight boards or to individual pens (IP) and fed a 16% CP diet at A o...
The present study was undertaken to examine the effect of recombinant chicken leptin administered to fed ad libitum and feed-restricted immature chickens of a layer strain on ovarian development and the timing of sexual maturity. In the first experiment 11-week-old pullets (77 days of age) fed ad libitum were injected daily with leptin at four dose levels (4, 16, 64 and 256 microg/kg body weigh...
________________________________________________________________________________ Abstract The study tested the performance of intact male pigs from a selected genetic line subjected to differing feeding regimens and penning conditions. The trial was a 2 x 3 x 2 x 3 factorial design, consisting of winter and summer periods, three sire lines, two diets and three feeding regimens. The pigs were in...
This study investigated the effects of hydration status and fluid availability on appetite and energy intake. Sixteen males completed four 24 h trials, visiting the laboratory overnight fasted on two consecutive days. Standardised foods were provided during the 24 h and on day two an ad-libitum semi-solid porridge breakfast was provided. Water intake during the 24 h (0 or 40 mL⋅kg(-1)) and flui...
Juvenile Chinese three-keeled pond turtles (Chinemys reevesii) were subjected to one of four different feeding regimens: ad libitum (AL), restricted (R), ad libitum-restricted (AL-R), or restricted-ad libitum (R-AL) for 13 weeks, to assess the compensatory growth (CG) response to food restriction and subsequent re-alimentation. After switching to ad libitum feeding, the turtles in R-AL group at...
Higher-protein meals decrease hunger and increase satiety compared to lower-protein meals. However, no consensus exists about the different effects of animal and vegetable proteins on appetite. We investigated how a meal based on vegetable protein (fava beans/split peas) affected ad libitum energy intake and appetite sensations, compared to macronutrient-balanced, iso-caloric meals based on ani...
