the effects of different levels of whole cottonseed (wcs) on feedlot performance and morphology of small intestine were studied in a completely randomized design with four diets containing 0, 4, 8 and 16 percent wcs on 20 chaal male lambs for 90 days. the metabolisable energy and proteins contents of rations were equal. number and dimensions of different types of villi and depth of crypt gland ...

the effects of different levels of whole cottonseed (wcs) on feedlot performance and on themorphology of small intestine, in 20 chaal male lambs were studied for a duration of 90 days. acompletely randomized design of four diets containing 0, 4, 8 and 16 percent wcs was employed.number and dimensions of different types of villi and depths of crypt gland were evaluated. themetabolisable energy a...

abstract: this study was conducted to investigate the effects of diets containing different levels of hull-less barley on caecal microflora of broiler chicks. two hundred and forty one-day old male broiler chicks (arbor acres strain) were used in a completely randomized design with 4 tratments, and 3 replicates were allocated to each treatment. different levels of hull-less barley in diets had ...

The study was conducted with a completely randomized design consisting of four treatments in triplicates. Experimental diets were formulated to contain four different lipid levels (8, 10, 12 and 14%) at constant protein level (46.8%) and different gross energy of 4314, 4417, 4519 and 4622kcal/kg, respectively. Kutum fry (average weight, 203±4mg) were randomly assigned and distributed at a densi...

In the course of the 19th century, chemists and physiologists studying the composition of foods and the nutritional requirements of humans and animals found that our diets needed to include the complex nitrogenous compounds called "proteins" (that, with water, form the bulk of our lean tissues), together with fats, starch and sugars that all provide usable energy during their oxidation in the b...

Twelve (12) weeks feeding trial was conducted to determine the effect of fatty acid content/total lipid and carcass characteristics/organoleptic qualities of broiler fed diets supplemented with dietary fat sources at levels of 5% saturated and 5% unsaturated. Three experimental diets identified as T1, T2 and T3 were formulated, the control diet T1 was with 0% fat, T2 contained palm oil at 5% in...

The study was conducted to evaluate the effect of feeding different levels of Guar germ on fattening performance of sheep. Twelve Sudan desert lamps of an average body weight (17.6 kg) were used in feedlot performance trial for 60 days. Four rations: A control, B, C and D were formulated, they consist different levels of guar germ (0, 15, 25 and 32%, respectively). The rations were prepared to ...

Citric acid has been reported to increase utilization efficiency of dietary phytate-bound phosphorus and protein. Objective of this study was to determine the effects of citric acid on growth performance and nutrient retention of broiler chickens fed diets having two levels of non-phytate phosphorus and rice bran. Giving a completely randomize design in 2 × 2 × 2 factorial arrangement, 144 broi...

To determine if previously observed ef fects of dietary protein on hepatic cysteine metabolism were due specifically to increases in dietary protein or to the accompanying decreases in dietary carbohydrate, two experiments were conducted. In one experiment, rats were fed diets that contained different levels of protein vs. an isocaloric mixture of fat + cellulose and a constant amount of carboh...
