the hypothesis of this experiment was that the various sources of dietary fat with different dietary ratios of polyunsaturated fatty acids (pufas) to saturated fatty acids (sfas) would alter the reproduction parameters of mature rams. twelve mature rams were randomly allotted to one of four dietary treatments in a completely randomized design. dietary treatments were: 1) ration with 4% soybean ...

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...

the effect of barley grain processing and source of supplemental fat on performance of lactating dairy cows were studied in a replicated 4 × 4 latin square design with 21-d periods and a 2 × 2 factorial arrangement. eight holstein cows with mean body weight (bw) of 572 ± 71 kg and 45 ± 10 days in milk were allocated to 4 dietary treatments including 1) ground barley with cottonseed 2) pelleted ...

In an attempt to determine the effect of dietary energy source on the quantity of abdominal fat in broilers, three levels of dietary animal fat (4, 7, and 10%) in isocaloric and isonitrogenous diets were fed in place of a carbohydrate energy source. Three trials were conducted. As dietary animal fat increased, the amount of abdominal fat in broilers increased under both a moderateand a high-tem...

The objective of the current study was to evaluate the effect of dietary fat type and level on broiler meat quality. A 2 × 3 factorial arrangement with 2 types of fat including neutralized sunflower soapstock (NSS) and soybean oil (SO) at 3 levels of fat inclusion (2, 4, and 6%) was used with 5 replicates per treatment using 750 one-day-old broiler chicks in a completely randomized design. At t...

background pancreatic cancer (pc) is classified as one of the most deadly cancers. since the role of diet in modifying the effects of known risk factors of pc has been well established, exploring the dietary intakes in relation to the etiology of pc can be useful for elucidating the mechanisms of the disease progression. methods and materials this study was conducted within the golestan prospec...

The present study investigated the effects of the supplemental dietary energy source on early lactating cows in a positive energy balance. Cows in the control group were fed a basal total mixed ration containing high-quality hay as forage, and the dietary concentrate to forage ratio was 45:65. The corn supplementation resulted in a significant decrease in the milk fat content (P < 0.05) and a l...

BACKGROUND Fatty acids play a vital role in glucose homeostasis; however, studies on habitual dietary fat intakes and gestational diabetes mellitus (GDM) risk are limited and provide conflicting findings. OBJECTIVE We determined whether the total amount and the type and source of prepregnancy dietary fats are related to risk of GDM. DESIGN A prospective study was conducted in 13,475 women w...

We studied the influence of dietary fat source and dl-α-tocopheryl acetate and ascorbic acid supplementation on the sensory quality of cooked dark chicken meat stored at −20 C for different periods. Results showed that dietary fat source and α-tocopheryl acetate supplementation influenced sensory scores (rancid flavor and aroma and acceptability). Ascorbic acid had no influence on these scores....
