abstract: large quantities of beef and mutton tallow are available in iran every year. if these products are processed and formulated properly and scientifically, the need to import oils and fats in a substantial quantities might be reduced. the aim of this study is to fractionate beef tallow into different fractions and carry out physical and chemical tests on each isolated fraction. beef fat ...

Due to its high lipid content and intricate constitution, food waste poses a considerable challenge for biotreatment. This research aims investigate the potential influence of diverse species on anaerobic fermentation, induced by varying dietary patterns observed in distinct regions. The investigation involved incorporating 5% (w/w) beef tallow, mutton fat, soybean oil, peanut rapeseed separate...

Thirty eight veal calves aged 7 weeks were fed milk replacers containing either coconut fat or tallow for a period of 15 weeks. Body weight gain was 114.2 10.3 and 115.7 22.5 kg (mean SD, n = 19, P > 0.05) for the calves fed the diets with either coconut fat or tallow, respectively. Faeces were collected during the last week of the trial. Apparent digestibility of crude fat was 93.3 4.9 and 91....

The Wnt signaling pathway plays an essential role in carcinogenesis, and the amount of fat intake and composition of dietary fatty acids are crucial factors for colon carcinogenesis. We investigated whether various dietary fats affected the Wnt signaling pathway of colon tumorigenesis in azoxymethane (AOM)-treated rats. Male Sprague-Dawley rats were given intraperitoneal injections of AOM and s...

BACKGROUND Evidence indicates that different types of fat have different effects on the postprandial plasma triacylglycerol response. Therefore, the type of fat may influence the appearance of beta-carotene in postprandial triacylglycerol-rich lipoproteins, which is used as an indicator of intestinal beta-carotene absorption. OBJECTIVE We compared in female subjects the appearance of beta-car...

This work was designed to investigate the effect of different lipid sources on ob gene expression and serum leptin levels in rats with two different feeding protocols: (1) free access to food; or (2) energy-controlled feeding. Male Wistar rats were fed diets containing 40 % energy as fat (olive oil, sunflower oil or beef tallow), for 4 weeks. In Expt 1 rats had free access to food, and in Expt ...

A 2 x 2 x 2 factorial experiment was conducted to evaluate the effects of fat type (beef tallow [50 g/kg diet] or canola oil [50 g/kg of diet]), carbohydrase addition (none or carbohydrases [0.4 g/kg diet]), and lipase addition (none or lipase [0.2 g/kg of diet]) on growth performance and nutrient utilization of male broilers fed a wheat-based diet from 5 to 18 d. The carbohydrase supplement co...

two hundred eighty days old male broiler chicks(ross strain) were randomly distributed into seven groups with four replicates (10 birds in each replicate) and were fed diets supplemented with different dietary fat sources.the results indicated that the different dietary treatments did not affect weight gain, feed intake and feed conversion ratio at 21 d (p>0.05). however, addition of dietary fa...

The effects of source of energy and energy restriction during lactation on sow and litter performance were investigated in an experiment with 90 primiparous sows. At parturition, the sows were randomly assigned to diets containing either tallow or cornstarch as a major energy source. Energy intake was restricted to 8 Mcal of metabolizable energy X sow-1 X d-1 during a 28-d lactation. All sows r...
