A lower price on poultry meat, compared with other meats (beef, pork etc.), affects the increasing demand for poultry meat. The productivity and production cost of broiler chickens are directly related to the amount of feed fed, the proportion of crude protein in the feed, and the biological value and price of the feed. The EU produces only 30% of the protein crops used for feed; thus, the larg...

the effect of feeding different protein profiles on growth performance, carcass components and nitrogen content of litter in cobb 500 broiler strain was evaluated using 800 chicks in a completely randomized design with four treatments, five replicates groups of 40 birds per each treatment. the treatments were consisted of four protein feeding profiles (based on cobb strain nutrition guide, reco...

Plant proteins are plausible fishmeal substitutes but are deficient in some essential amino acids (EAA) like lysine and methionine. Combination of different plant proteins with complimentary EAA could be useful alternative. Bambaranut (Voandzeia subterranea) contains high amount of lysine while methionine is in sesame seed (Sesamum indicum). This experiment tested effects of combining sesame se...

The aim of this study was to investigate the effects of various doses of essential oils (EO) of thyme (TEO) or cinnamon (CEO) on in vitro rumen degradation of protein of a commercial total mixed ratio (TMR) containing 16.4% crud protein (CP). Treatments were TMR without any of EOs (control); control plus 25 µL of TEO (TEO25); control plus 50 µL of TEO (TEO50); control plus 25 µL of CEO (CEO25) ...

this experiment was designed to evaluate the effect of phenolic components of scrophularia striata powder on feed intake, digestion and fermentation, rumination kinetic and rumen ecosystem in lori-bakhtiari sheep. in this experiment, 12 six months old lambs and average weight 30±1.5 kg were fed with 0 (control), 3 and 6 percent scrophularia striata for one month. feed intake, digestibility, rum...

The price of aqua feed containing Dunaliella salina meal was calculated. Also, the formulated feed’s protein, lipid, and total carotenoid content were examined. shrimp D. higher than commercial with better protein in feed. This indicated that inclusion microalgae may increase coloration growth shrimp. We recommend using these fish aquaculture necessary investment production.

in turkey, it is known that, wastes of fisheries processing plants released to the environment and only a bit of that assessed as fish meal or fish feed by a few plant. it is expected that with the evaluation of these wastes which rich in nutrient content by converted to the various commercial products (chitin, protein hydrolyzate, carotenoprotein and pıgment extraction etc.) to be beneficial i...

A high concentrate diet was fed at 1.2, 1.5, 1.8 and 2.1% of body weight to four Angus steers (258 kg) equipped with cannulas in the proximal duodenum and distal ileum. As level of feed intake increased, flow of N, nonammonia N, microbial N and feed N to the small intestine increased linearly (P less than .05). Bypass of feed N increased from 44 to 71% of fed N. At the highest intake level, rum...
