Recent studies have indicated that egg yolk immunoglobulins (Ig) can be used for therapeutic purposes and that yolk Ig levels are increased after molting of laying hens. The present study was performed to compare between the effects of two methods of induced molting namely alfalfa and zinc methods on serum and yolk IgY concentrations as well as their effects on the egg quality and immune status...

Abstract The aim of this study was to assess the effect adding different levels date fruit in ration on accelerated puberty and sexual maturity Frisian heifers raises South Iraq. Sixty-four (4 months-old) were equally allocated four groups (16 each). All fed same ration, first group (T1) without any additive, while second (T2), third (T3), fourth (T4) 0.5, 1, 2 kg fruits/head/day, respectively ...

The purpose of this study was to assess the compensatory responses to food restriction and subsequent increased food availability in juvenile green turtles (Chelonia mydas). Turtles were fed an ad libitum ration for 12 weeks (AL), a restricted ration for 12 weeks (R), or a restricted ration for 5 weeks and an ad libitum ration for 7 weeks (R-AL). Analysis of covariance was used to test the rela...

Forages are the most important ingredient in a dairy cow’s ration. She is a ruminant and to be a healthy, productive cow she needs a healthy, productive rumen. High quality forages are the key to achieving a healthy rumen and a productive cow. However, because of the importance of forages in maintaining rumen health and cow performance, when deficiencies in the amount or quality of the forage i...

Two experiments were conducted to determine apparent ileal DM and crude-protein (CP) digestibilities in rations fed to pigs. An evaluation was made of Cr2O3 and HCl-insoluble ash as digestive markers. In addition, the effects of body weight (BW) on apparent ileal DM and CP (N x 6.25) digestibilities were studied. In Expt 1, thirteen barrows averaging 35 kg BW were fitted with post-valve T-caecu...

BACKGROUND Gut microbiota provide functions of importance to influence hosts' food digestion, metabolism, and protection against pathogens. Factors that affect the composition and functions of gut microbial communities are well studied in humans and other animals; however, we have limited knowledge of how natural food web factors such as stress from predators and food resource rations could aff...

Growth, feed conversion ratio and fillet composition of rainbow trout (initial weight of 9.99±0.109)were investigated in a 6x2 factorial design experiment employing two levels of digestible energy (DE) (2900 and 3500kcal.kg-1) and six feeding rates (1.0%, 2.0%, 3.0%, 4.0%,5.0% of the body weight,(BW) day-1 and to satiation) for 60 days. Specific growth rate (SGR) was highest at 5.0% ration in b...

Several reports in the literature suggest a possible relationship between riboflavin deficiency and anemia. Intramuscular administration of purified flavin prepared from liver was reported by Stare and Thompson (1) to have no effect on hemoglobin, erythrocyte, or reticulocyte response in patients with pernicious anemia. However, Miller and Rhoads (2) were able to produce in dogs a syndrome simi...

Micronutrient deficiencies occur frequently in refugee and displaced populations. These deficiency diseases include, in addition to the most common Fe and vitamin A deficiencies, scurvy (vitamin C deficiency), pellagra (niacin and/or tryptophan deficiency) and beriberi (thiamin deficiency), which are not seen frequently in non-emergency-affected populations. The main causes of the outbreaks hav...
