this experiment was carried out in order to study the effect of ionophore anticoccidial drugs (salinomycin, maduramycin and their combination) and the comparison of those effects on the performance, carcass characteristics and concentration of some minerals of serum in broiler chicks. this experiment was included four treatments: 1) basal diet, 2) basal diet with 60 mg/kg salinomycin, 3) basal ...

The study evaluated replacement of Egyptian berseem clover (BC, Trifolium alexandrinum) with spent rice straw (SRS) of Pleurotus ostreatus basidiomycete in diets of lactating Baladi goats. Nine lactating homo-parity Baladi goats (average BW 23.8±0.4 kg) at 7 d postpartum were used in a triplicate 3×3 Latin square design with 30 d experimental periods. Goats were fed a basal diet containing 0 (C...

BACKGROUND Previous military studies have shown an energy deficit during a strenuous field training course (TC). This study aimed to determine the effects of energy bar supplementation on energy balance, physical activity (PA), physical performance and well-being and to evaluate ad libitum fluid intake during wintertime 8-day strenuous TC. METHODS Twenty-six men (age 20±1 yr.) were randomly d...

A twoto four-fold increase in corn prices in recent years over historical trends has prompted many questions about alternatives to corn for dairy rations. As corn is a low protein high energy feedstuff, its continued use even with high prices or concern over its partial replacement is mainly confined to rations for lactating cows where meeting the energy requirements of milk production is impor...

Though various chemical and microbiological methods have been developed for the estimation of vitamin Bs in whole (2-4) or in part (5), animal assays are still necessary for testing the accuracy of these new methods as they apply to animal nutrition. It is also important that the relative potency of pyridoxine, pyridoxamine, and pyridoxal for animals be known. Two different purified rations hav...

this study investigated the effect of dietary supplementation with calcium salts of fatty acids using 48 afshari ewes randomly allocated to four treatments. all groups used in flushing period and only the source of energy were different between rations. the ewes were divided into four groups: a-barely grain; group b-received 5% of csfa with source of flaxseed oil (w3); group c-received 5% of cs...

Phenotypic flexibility is critical in determining fitness. As conditions change during ontogeny, continued responsiveness is necessary to meet the demands of the environment. Studies have shown that subsequent ontogenetic periods of development can interact with one another and shape developmental outcomes. The role genetic variation within populations plays in shaping these outcomes remains un...

This study aimed to compare local dairy farmer ration formula with national research council in producing higher feed efficiency and milk production. This study had two stages. The first stage was in vitro study of dairy farmer rations which have different raw materials (R3, R4, and R5) with NRC based ration (R2) and Demo Farm ration (R1). The variables measured in this stage were proximate com...

In 1938 Schantz, Elvehjem, and Hart (1) reported that rats, calves, and pigs which received liquid skim milk as their sole diet excreted a considerable amount of galactose in the urine. No such excretion occurred when whole milk was fed. In studies with the rat it was found that the addition of 3 to 4 per cent of fat to the skim milk completely prevented the urinary loss of galactose, and furth...
