this experiment was carried out for a period of 4 weeks with 240 day old straight- run broiler (cobb-500) chicks to investigate the effects of administering electrolytes in drinking water on the productive performance (live weight, body weight gain, feed consumption, feed conversion and water consumption) and to determine the economic impact of using electrolytes. the chicks were randomly distr...

an experiment was conducted with two hundred and twenty day-old male broiler chicks (ross 308) in five groups to investigate the effects of different levels of 0, 0.2, 0.4 and 0.6% thyme extract in drinking water (including 27.4 mg sodium nitrate per liter) on broiler performance and antioxidantstatus and blood gas indices. no significant differences were observed between the treatments for bod...

Dairy waste is a complex mixture of nutrients requiring an integrated strategy for valorization into various products. The present work adds insights into the conversion of fat-rich dairy products into biomass, glycerol, and fatty acids via submerged cultivation with edible filamentous fungi. The pH influenced fat degradation, where Aspergillus oryzae lipase was more active at neutral than acid...

this experiment was conducted to determine the effects of the oral consumption of guggulplant resin on the performance and humoral immunity response of broiler chicks. for doing this experiment, 320 one-day old chicks of the cobb 500 strains, in a completely randomized design with 4 treatments and 4 replicates were used. experimental diets include: control diet (without the guggul), control die...

The project was planed to study the effect of varying dietary cation-anoin balance on the growth performance of broilers. One hundred and twenty day-old (Hubbard) broiler chicks were purchased from a local hatchery and reared in a group for one week of age. At the start of second week, birds were randomly distributed in 12 pens (10 chicks per pen). Four isonitrogenous and isocaloric starter and...

Extralabel drug use of penicillin G in food-producing animals may cause an excess of residues in tissue which will have the potential to damage human health. Of all the antibiotics, penicillin G may have the greatest potential for producing allergic responses to the consumer of food animal products. There are, however, no population pharmacokinetic studies of penicillin G for food animals. The ...

The efficacy of top-dress antiinflammatory drugs ultimately depends on a patient's willingness to consume treated feed. The current study compares the palatability of two phenylbutazone top-dress formulations (Equipalazone Powder, Dechra Pharmaceuticals, and Pro-Dynam, VetXX, Ltd.) and a suxibuzone top-dress formulation (Danilon Equidos, Janssen Animal Health). Results of a three-period, crosso...

To determine the effect of using Aloe vera and protexin probiotic on performance, carcass characteristics and some blood biochemical in Japanese quails, a total 300 ten days old Japanese quails quail chicks with an average weight of 19.5±5 g were divided into 8 treatments with 3 replicates as factorial randomized design experiment. The quails were fed by basal diet as control diet, (0 and 1 g.k...

Nine ewe and eight wether weanling lambs were fed a pelleted diet containing 60% roughage and 40% concentrate for 12 h/day. Feed consumption (FC) was measured during the first 30 and 60 min (FC-30, -60). Total daily consumption (FCT) was also measured. With these data, feed efficiency (FE), eating rate index (ERI = FC/BW.75) and propensity to eat (percentage FC/unit of time) were calculated. Af...

The amino acid requirements of growing animals are predicted to change with time, due to changes in the requirements for maintenance and for growth. Because food intake also changes with time, the question of optimising the dietary concentrations of a m i n o a c i d s d u r i n g t he g rowing period of animals is difficult to rcsolvc w i t h o u t resorting to computer mod&. Even such models ...
