Organic acids can be replaced as effective feed additives with antibiotics. Organic acids and their salts have the potential to retard the development of pathogens in the diets and thus maintain the microbial equilibrium in the gastrointestinal tract. In this study, 225 day-old broiler chicks were used for a period of 21 days in order to examine the effect of different levels of organic acids (...

This study was conducted to determine the effect of different levels organic copper (organic Cu) supplementation on performance, egg quality, serum parameters and incubation characteristics in Japanese quail diets. 120 breeder quails 7 weeks old were used lasted 84 days. Four diets containing (0, 75, 150 225 mg/kg) study. The a random design consisting 20 subgroups with 5 replicates, 4 females ...

Consumer-diet discrimination factors (Δ15N and Δ13C) are often applied without corroboration from laboratory experiments. Deviations in Δ15N and Δ13C that may occur from different diet types were quantified by raising 120 sea urchins Lytechinus variegatus in laboratory tanks on 3 different diets: seagrass Thalassia testudinum, red foliose macroalgae (Grauteloupia sp. and Palmaria palmata) and a...

The objective of this experiment was to quantify intakes, duodenal flows, and ruminal apparent synthesis (AS) of B-vitamins in lactating dairy cows fed diets varying in forage and nonfiber carbohydrate (NFC) contents. Eight (4 primiparous and 4 multiparous) ruminally and duodenally cannulated Holstein cows were assigned to 4 dietary treatments in a replicated 21-d period, 4 x 4 Latin square des...

for this reason the samples were obtained from three area in kerman province that cartivate corn in large amounts (giroft, kahnooj, baft).the amounts of samples were enough for both voluntary consumption and investigation of digestibility. after that samples had been chopped by electric chopper we sampled again from every sample and its chemical compositions were determined with standard method...

OBJECTIVE An experiment was conducted to evaluate effects of inclusion level of palm kernel meal (PKM) and adaptation duration on the digestible energy (DE) and apparent total tract digestibility (ATTD) of chemical constituents in diets fed to growing-finishing pigs. METHODS Thirty crossbred barrows (Duroc×Landrace×Large White) with an average initial body weight of 85.0±2.1 kg were fed 5 die...

Relationships between ammonia levels in rumen liquor and dietary nitrogen (N) intake, the N concentration in the diet, blood urea concentration and urinary N excretion were examined in sheep fed near ad libitum on diets varying widely in chemical composition and digestibility. Rumen ammonia was positively correlated with all measures but the best relationship was with the ratio of N to digestib...

the effects of replacement of alfalfa hay with pistachio by-product (pb) at 0, 25, 50, and 75% (dm basis) on the ruminal parameters, dry matter intake (dmi) of female rayini goats, after kidding, and on the live weight gain (lwg) of their kids were investigated. five single-bearing female rayini goats each with a single kid were employed in each level of replacement. the basal diet contained ba...

Organic milk production has increased rapidly in many European countries during the last decade but the merits of organic dairy products are still disputed. Little unbiased information exists regarding any essential differences in gross composition or other parameters of technological and/or nutritional interest. In order to gather more basic information regarding organic milk, raw milk samples...
