There are many studies on the effects of probiotics on performance of broiler chickens, but none of them has evaluated the metabolizable energy (ME) equivalency values of probiotics. The aim of this study was to determine the metabolizable energy equivalency value of Bacillus subtilis spore and its potential for decreasing feed ME content and cost. One hundred seventy-six day-old male broilers ...

the present experiment was conducted to determine metabolizable energy of pomegranate peel and pulp by adult cockerels. the pomegranate peel and pulp samples were gathered from three industries. this study had two experiments. each experiment was done in a completely randomized design with 4 treatments and 4 replicate (1 cockerel each). the cockerels fed conventional addition method (cam). the ...

this study was conducted to determine the chemical composition and metabolizable energy of poultry by-product meal (pbpm) from two slaughterhouses in iran. samples were analyzed for dry matter, crude protein, ash, ether extract and gross energy. the amounts of calcium, phosphorus, sodium, potassium, magnesium, iron, manganese, copper and zinc were determined. the apparent metabolizable energy (...

Two experiments were conducted to determine the chemical composition, metabolizable energy content and effect of grape pomace (GP) with or without tannase enzyme treatment on growth performance of broiler chickens. In experiment 1, the apparent metabolizable energy (AME) and apparent metabolizable energy corrected for nitrogen (AMEn) of GP were determined as 2642.19 and 2641.08 kcal/kg, respect...

Fats and oils are chemically diverse group of compounds, which have the highest energy density among all macro nutrients. Besides having high caloric values, they are major sources of essential fatty acids (Ω-3 and Ω-6), fat soluble vitamins (A, D, E and K) and lecithin. Moreover, supplementation of fats and oils to poultry rations increases the metabolizable energy of the total ration, the cal...

Forty-five energy balances were completed with 12 multiparous, lactating Holstein cows in a study designed to determine the energy content of wet corn distillers grains. Treatments were applied in a repeated switchback design and consisted of total mixed diets containing 31.4% corn silage, 18.4% alfalfa hay, and either 30.7% rolled corn and 16.7% soybean meal or 17.0% rolled corn and 31.2% wet ...

OBJECTIVE Despite the fact that most obesity drugs primarily work by reducing metabolizable energy intake, elucidation of the time course of energy intake changes during long-term obesity pharmacotherapy has been prevented by the limitations of self-report methods of measuring energy intake. METHODS A validated mathematical model of human metabolism was used to provide the first quantificatio...
