Several major chronic diseases that afflict the elderly are in part related to excess dietary fat. This needs to be balanced against the nutritive value of fat and the tendency for elderly people to eat less fat by choice. Recommendations to the elderly on how much fat they should eat are therefore complex. What type of fat to eat is simpler. Food lipids hâve many nutritional and biological fun...
A total of 700 day old female broiler chicks (Ross 308) were distributed into seven groupsin acompletely randomized designwith five replicates, and 20 chicks in each replicate. Dietary treatments, timeof the switch from an unsaturated sunflower oil (SFO) to a saturated tallow (T)dietary fat source, were: 1) SFO for the entire growth period (6 weeks), 2) SFO for 5 weeks followed byT for last wee...
Crossbred pigs (n=288) were used to test the interactive effects of dietary fat source and slaughter weight on dissected carcass composition and fatty acid composition of composite carcass samples. Pigs were blocked by initial BW, and within each of 9 blocks, pens (8 pigs/pen) were randomly assigned to either control corn-soybean meal grower and finisher diets (Ctrl) or diets formulated with 5%...
Two experiments investigated the quantitative relationship between dietary fat and fatty acid composition of pork. Experiment 1 was designed to establish the rate of decline for linoleic acid and iodine value of pork fat during the late fattening phase following a dietary reduction. Gilts (n = 288) were fed diets varying in linoleic acid content from 4.11 to 1.56% for 4, 6, or 8 wk prior to sla...
2. Maximal lactational response in different experiments depended upon wha t Mg source was supplemented and the milk production level (stage of lactation) of cows . For midlactation cows supplemented with feed grad e magnesium phosphate, .48% total dietary Mg resulted in greatest milk yield . When midlactation cows were provided additional dietary Mg as Mg O maximal lactational response was obt...
Crossbred pigs (n = 216) were used to test the interactive effect, if any, of ractopamine (RAC) and dietary fat source on the performance of finishing pigs, pork carcass characteristics, and quality of LM chops during 5 d of simulated retail display (2.6 degrees C and 1,600 lx warm-white fluorescent lighting). Pigs were blocked by BW and allotted randomly to pens (6 pigs/pen), and, after receiv...
Prostate cancer is a growing problem in New Zealand and worldwide, as populations adopt a Western style dietary pattern. In particular, dietary fat is believed to be associated with oxidative stress, which in turn may be associated with cancer risk and development. In addition, DNA damage is associated with the risk of various cancers, and is regarded as an ideal biomarker for the assessment of...
The aim of this experiment was to assess the effects of four different feeding programs designed to include tallow, a saturated fat at 0, 8, 12, and 28 d prior to slaughter on female broiler performance and the deposition, fatty acid profile, and melting point of abdominal fat. The following treatment groups were established according to dietary inclusion--from 21 to 49 d of age--of: sunflower ...
An experiment was conducted to study the effects of major dietary energy source fed from weaning to ovulation or from ovulation to d 35 of pregnancy on reproductive traits in primiparous sows. Dietary energy sources were used to manipulate the plasma insulin concentration. One hundred thirteen sows were used in a split-plot design. From weaning to ovulation sows were fed at two times maintenanc...
Influence of Dietary Fat Source on Growth Performance Responses and Carcass Traits of Broiler Chicks
This study was conducted to determine the effects of three different fat sources and their combination on growth performance, carcass traits and intestinal measurements of broiler chickens reared to 42 d of age. Two hundred day-old male broiler chicks (Ross 308) were randomly assigned to one of five treatments with four replicates of 10 chicks based on a completely randomized design. The dietar...
