China Title: Effects of vitamin D3 on expression of defensins, Toll-like receptors, and vitamin D receptor in liver, kidney, and spleen of Silky Fowl Abstract: 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 8-24 h post injection. These results suggest that expression of VDR, AvBDs, and TLRs seems to be induced by vitamin D3 and it was concluded that the tissues expressing TLRs and VDR respond to vitamin D3 and in turn upregulate these tissues cellular functions to synthesize AvBDs. Intraperitoneal injection of vitamin D3 likely resulted in enhancing the expression of AvBDs, TLRs, and VDR, which providedinsight into factors important for the control of the innateimmune response in the chickens.

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) with 25 µg/kg BW 3 days apart; group D, injected twice with 10 µg/kg BW 3 days apart. After stripping, the pseudo-gonadosomatic index was calculated, and an eggs sample from each female was fertilized. Only fish in the groups treated with DI protocols ovulated. No differences between the two groups were found in the timing of ovulation, ovulation rate, or mean time to ovulation. No females in either group A or B ovulated, since the experiment had to be prematurely terminated due to technical problems at the field hatchery. The DI of 10 µg/kg proved sufficient to induce and advance ovulation in Arctic grayling. Hormone treatments seem to be a promising tool to obtain viable eggs of Arctic grayling in a short time window and thereby to ensure satisfactory numbers of fry for restocking programs.

China Title: Effect of maternal undernutrition during late pregnancy on hormonal status and metabolic changes in neonatal lambs Abstract: 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 neonatal lambs in each group and analyzed for growth hormone (GH), insulin-like growth factor I (IGF-I), IGF-II, insulin (INS), thyroxine (T4), triiodothyronine (T3), glucose (GLU), nonesterified fatty acids (NEFA), and total amino acid (TAA), respectively. The results indicated that the maternal undernutrition during late gestation decreased the average lamb birth weight in both RG1 (P < 0.01) and RG2 (P < 0.05) compared to CG. During the late fetal development period, the concentrations of T4, INS, and IGF-I of neonatal lambs in CG were increased (P < 0.05) compared to those at day 90 of pregnancy; the secretions of T4, INS, and IGF-I in RG1 and RG2 during restriction were suppressed. The neonatal INS concentrations in RG1 and RG2 were decreased (P < 0.05), but the neonatal GH concentration in RG1 was greater than that of CG (P < 0.05). The GLU concentrations of neonatal lambs in RG1 were lower than those of CG (P < 0.05). However, the neonatal NEFA (P < 0.05) and TAA (P < 0.01) concentrations in RG1 were greater than those of CG. Thus, maternal undernutrition can change the hormonal and metabolic status of neonatal lambs, which may have significant implications on postnatal growth and adult health.

Wolfová Author-Workplace-Name: Institute of Animal Science, Prague-Uhříněves, Czech Republic Title: Impact of economic parameters on economic values in dairy sheep Abstract: 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 most important traits: milk yield in the 150-day milking period, conception rate of ewes, litter size per lambed ewe, and productive lifetime of ewes. Furthermore, cumulative relative economic values of the four trait complexes - milk production, growth, functional, and wool traits - were presented. Prices for sheep products were found to be the most important factor for both the marginal and the relative economic values of the evaluated traits. The four traits with the highest relative economic values in the base calculation stayed the most important for all investigated economic parameters ranges. The relative economic values of the remaining 10 traits did not exceed 6.1%. The relative economic values of milk yield and litter size were the most sensitive to the variation in economic circumstances. For the investigated range of economic parameters, the relative economic value for the complex of milk production traits ranged 30.6-48.1%, for growth traits 6.3-9.4%, and that for functional traits 45.4-59.7%. The relative economic value for the wool trait did not exceed 0.3%.

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 - in recrudescent females it increased mRNA levels at the dose of 1 mg/kg, while in the preovulatory period all of the used pimozide doses (1, 5, and 10 mg/kg) were responsible for the increase of prolactin mRNA levels. Taken together, the above results suggest that gonadotropin releasing hormone (GnRH) is the factor responsible for the stimulation of prolactin synthesis, while dopamine has an inhibitory influence on the prolactin production.

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, animals were fed a high-Se diet (5.0 mg Se/kg dry matter). Throughout the trial, 4 samples of blood and ruminal fluid were taken from each animal. The samples of ruminal fluid were analyzed to determine the concentration of Se and identify other parameters of ruminal fermentations. Selenium levels were also determined in ruminal biomass. In blood, Se concentration, glutathione peroxidase (GSH-Px) activity, and other selected biochemical parameters were measured. The results of the present study demonstrate that the actual intake of both organic and inorganic Se is reflected in Se concentration in ruminal fluid and ruminal biomass and, similarly, in Se content and GSH-Px activity in blood. The form of supplemented selenium did not have a significant effect on ruminal fermentation parameters in dependence on different doses of Se contained in feeding rations (except for the negative effect of a sudden start of feeding high levels of organically bound Se on infusoria count, which was accompanied by the increase of GMT, LDH, and AST enzymes activity in ruminal fluid). The results also suggest possible negative interaction between the intake of organically bound selenium and the concentration of copper in blood of sheep.
