Cryopreservation protocols induce partially irreversible damage to mammalian sperm plasma membranes. Previous studies have indicated that adding cholesterol to the plasma membrane, as cholesterol-loaded-cyclodextrins, improves cryosurvival of sperm. Therefore, the purpose of this study was to determine if treating sperm of Markhoz bucks with cholesterol-loaded-cyclodextrins (CLC) (0, 0.75, 1.5,...
Objective: In this study, the effect of diet food (soybeans, egg yolk and chicken manure) on biomass weight and body composition (the amount of protein, fat, moisture and ash) Chironomid larvae were examined. Methods: For this purpose, 2.5 grams of food per Coconut considered in the period, with three replicates and Chironomid larvae during the period of 15 days in plastic pans were kept in nut...
background: a large proportion of patients presenting with lumbar disc disease are opium addicts in our region. it was, therefore, hypothesized that morphine might affect the intervertebral disc. we investigated the histological findings of morphine dependency on intervertebral discs in rat. methods: forty nmri adult male rats (230-250 g) placed on ordinary diet and received aqueous solution ...
Motility of spermatozoa was studied on 12 and 7 specimens of Acipenser persicus and A. stellatus, respectively. The density measured to be 2.22±0.65x109ml-1 in A. persicus and 2.21±0.55x109ml-1 in A. stellatus. Semen samples were diluted with two extenders containing tris 118mM, sucrose 23.4mM, pH=8, egg yolk (20%), dimethyl sulfoxide (15%) and penicillin potassium (500IU/ml) and biociphus exte...
the aim of this study was to determine the effects of ecg, pgf2α and gnrh hormone on improvement of reproduction performance of cidr synchronized zandi ewes in breeding season. 500 ewes with age of 2.5-4 years and same nutritional condition were selected for this study and received cidr for 12 days. then these ewes were assigned to five equal groups. first group received no hormone (control gro...
White leghorn hens were immunized intramuscularly with formalin killed Klebsiella pneumoniae cells to generate Klebsiella pneumoniae antibodies (IgY) in egg yolk. Booster injections of increasing concentrations of antigen were given to raise the antibody level in egg yolk. Amount of protein varied from 0.87 7.4mg/ml in egg yolk throughout the immunization period. The antibodies were partially p...
In the liver and the yolk sack of 6-12 week postfertilization human embryos, we have detected RNA transcripts from the following apolipoprotein genes: AI, AII, B, CII, CIII and E. The mRNA from the apolipoprotein CIII gene was relatively more abundant in the total RNA from the yolk sack than in that from the liver. The gut and adrenals contained transcripts of all these apolipoprotein genes apa...
background: improvement of hatchability in aging broilerbreeder has economic justification. objectives: the main objective ofthis study was to determine the effect of dietary anethum graveolensessential oil on egg quality, some plasma metabolites and hatchability inbroiler breeder hens. methods: a total number of eighty hens and eightcocks from ross 308 strain of 105 weeks old were divided into...
It is well established that in many avian species, prenatal maternal resource allocation varies both between and within clutches and may affect offspring fitness. Differential allocation of maternal resources, in terms of egg weight and yolk composition, may therefore allow the female to adjust brood reduction and to fine-tune reproductive investment in accordance with the expected fitness retu...
