The expression of avian β-defensins (AvBDs), Toll-like receptors (TLRs), and vitamin D receptor (VDR) following in vivo vitamin D3 injection was studied. Healthy 90-day Silky Fowls were abdominally injected with vitamin D3 or untreated. Real-time PCR analyses revealed that injection of vitamin D3 significantly (P < 0.05) up-regulated the expression of TLRs (TLR2, TLR5), VDR, AvBDs (AVBD-6, GAL-1), and 24-hydroxylase (CYP24A1) in the tissues (liver, spleen, and kidney) at various times...

The effect of single and double injections of D-Tle6,Pro9,NEt-mGnRHa (Supergestran®) on advancement and induction of ovulation in Arctic grayling was assessed. Sexually mature wild Arctic grayling females (most 2-4 years old) were caught in the Yenisey River at the beginning of May 2010. After a 4-day acclimatization, the females were randomly divided into four groups and intramuscularly injected as follows: group A, control group, treated with physiological saline only; group B, treated with a single injection (SI) of Supergestran® at 25 µg/kg body weight (BW); group C, injected twice (DI)...

The study investigated the consequences of maternal undernutrition during late pregnancy on hormonal status and metabolic changes in neonatal lambs. Four ewes out of twenty-eight multiparous ewes mated at a synchronized oestrus were slaughtered at day 90 of pregnancy to collect fetal blood to serve as an initial comparison group. Twenty-four animals were divided into three groups and offered 0.18 MJ ME.kg-0.75per day (restricted group 1, RG1), 0.33 MJ ME.kg-0.75per day (restricted group 2, RG2), and control group (ad libitum CG) during late pregnancy, respectively. Immediately after parturition, blood was collected from...

The impact of variation in economic conditions on the economic values of fourteen production and functional traits was examined for the Improved Valachian breed using a bio-economic model implemented in the ECOWEIGHT software. The following economic parameters were investigated: market prices of lambs, milk, and cheese (variation ± 40%), costs for roughage, concentrates, and total feeding rations , costs for labour and veterinary care, fixed costs (variation ± 20% for all costs), and discount rate of revenues and costs (0 and 3%). Results of the analyses were presented in detail for the marginal and relative economic values of the four...

Effects of salmon gonadotropin releasing hormone analogue (sGnRH-A) and antidopaminergic drug, pimozide, on the synthesis of prolactin mRNA in vivo in female Prussian carp (Carassius gibelio Bloch) during two different stages of the reproductive cycle were evaluated. The results showed that the lowest dose of sGnRH-A (5 μg/kg body weight) significantly stimulated the mRNA synthesis in fish during the recrudescence as well as during the preovulatory period, higher doses of this compound having no significant effect on prolactin mRNA synthesis. The blocker of dopamine receptors, pimozide, also potentiated prolactin mRNA synthesis...

Effect of various doses and forms of selenium (organically bound vs. inorganic) on selected parameters of ruminal fluid and blood in sheep was evaluated. The trial was performed with 15 sheep divided into two groups. Animals from group A (n = 8) received a feeding mixture with selenomethionine, while sheep from group B (n = 7) were fed a mixture with sodium selenite. During the first 14 days, animals from both groups were fed a mixture with optimum dose of selenium (1 mg Se/kg dry matter). For another 28 days, all experimental animals received a Se-deficient mixture (0.1 mg Se/kg dry matter), whereas in the last 21 days of the experiment,...
