These investigations aimed to evaluate the influence of acaricides used in Bulgaria (based on amitraz, cumaphos and fluvalinate) on some factors of the non-specific bee immunity in the appearance of chalkbrood. It was found that the changes of protein concentration and lysozyme amount in the haemolymph and the pH of bee intestine depend on different active substances of the drugs. Field trials canied out on 526 colonies revealed that the lower resistance of bees infected with Varroa jacobsoni was a cause of the appearance of chalkbrood. This resistance was additionally decreased by using the anti-Varroa mite product “Perizin”.

Wheat (Triticum aestivum L.) plants exposed to water deficit during ripening show altered agronomic and grain quality characteristics. Drought causes yield losses and seasonal variation in quality creating difficulties in the marketing and processing of grain, so improving the genetic adaptation of wheat cultivars to drought stress is an important objective in breeding programs. Some genotypes have been reported to have a tolerant response and could be used as genetic sources for drought tolerance. Five spring wheat cultivars from South America and two checks were evaluated in Uruguay. One controlled environment experiment was conducted in a split-plot design with two cycles of Progressive drought stress during grain filling. Agronomic characteristics as kernel number and aerial biomass decreased with drought stress. Significant genotype х treatment interaction with a decreasing effect was detected for root width, thousand kernel weight, and grain yield. No significant effect of drought stress was detected for root length or weight. Rheological properties were affected by drought stress increasing mixogram maximum height at peak (МНР) and mixogram time to maximum height (TMH). Significant genotype х treatment interaction was found for grain protein concentration, МНР and TMH. Cultivars with stable agronomic and quality characteristics under drought stress were found in this study. They could be used as genetic sources for resistance to this abiotic stress.

Background. The distillery stillage is a major and arduous byproduct generated during ethanol production in distilleries. The aim of this study was to evaluate the possibility of the stillage recirculation in the mashing process of triticale for non-byproducts production and reducing the fresh water consumption. The number of recirculation cycles which can be applied without disturbances in the ethanol fermentation process was investigated. MateriaL and methods. Winter triticale BOGO and “Ethanol Red” Saccharomyces cerevisiae yeast were used in the experiments. The method of non-pressure cooking was used for gelatinizing the triticale, commercial α-amylase SPEZYME ETHYL and glucoamyl- ase FERMENZYME L-400 were applied for starch liquefaction and saccharification. The process was conducted at 30°C for 72 h, next after distillation the stillage was centrifuged and the liquid fraction was used instead of 75% of process water. Results. Ethanol yield from triticale fermentations during 40 cycles ranged between 82% and 95% of theoretical yield preserving yeast vitality and quantity on the same level. The obtained distillates were characterized with enhanced volatile compounds (fusel oil, esters, aldehydes, methanol) as well as protein and potassium concentrations. Conclusions. The liquid part of stillage was proved that can be reused instead of water in bioethanol production from triticale, without disturbing the fermentation process. This investigated solution of distillery byproducts utilization (liquid phase of stillage) constitutes the way which could significantly decrease the bioethanol production costs by reducing the water consumption, as well as wastewater production.

Oxidative metabolism is essential for the gamete and the embryo energy production and is unavoidably associated with generation of reactive oxygen species (ROS). Enzymatic antioxidant defenses are present in the mammalian oocytes, embryos and follicular fluid (FF). An addition of porcine FF to maturation media have positive effects on the IVM and IVF results. The aim of this study was to study the CAT, SOD and GSH-Px activity, as well as Cu, Mn, and Zn concentration in porcine FF collected from the left and the right ovary. The ovaries were collected from 77 gilts at age 8 months. All the analyzed samples of FF revealed active enzymes (24.2·10–3 U · l–1, 2.65·10–3 U · l–1, and 525 U · l–1 for CAT, GSH-Px, and SOD, respectively) and contained Zn, Cu and Mn (13.8·103mol · l–1, 33.3·103 mol · l–1, and 133·10–9 mol · l–1, respectively). In the pFF collected from the left ovary, SOD and GSH-Px activity was higher compared to pFF from the right ovary. On the contrary, the concentration of Cu and Mn was significantly lower in the left ovary pFF. The concentration of Cu ions was negatively correlated with SOD activity. The CAT activity in pFF form left or right ovary did not show any differences.

The poultry industry in Nigeria keeps expanding on a daily basis and it is faced with the problem of egg glut almost yearly. Most of the poultry are raised in rural environments where there is no available and avoidable power supply for egg preservation. The study was aimed at using locally available and cheap materials for preservation of eggs quality under the hot ambient temperature. The eggs were divided into three groups of 80 eggs each. The first and second groups were treated with vegetable oil (soybean oil) and shea butter, respectively, while the third group served as control. The eggs were stored under the ambient conditions and assessed for their physical and nutritional qualities on days 1, 8, 15, 22, 29, 36, 43 and 50. The physical quality was assessed by determining the albumen height and the Haugh’s unit, while the nutritional quality was appraised through the protein concentration of the albumen. Based on the values of Haugh’s unit, eggs treated with vegetable oil produced excellent results; good quality eggs were obtained up to 50th day of storage. Treatment with shea butter maintained quality eggs up to the 29th day, while with untreated eggs good physical quality was maintained up to 22 nd day of storage. Protein concentrations of eggs in the three groups studied decline with duration of storage, however the protein concentrations of eggs treated with vegetable oil were significantly higher than the other groups (p<0.001). The eggs treated with shea butter recorded a comparative higher protein concentrations than the untreated eggs (p=0.002).

Leptin is a 16-kDa protein hormone encoded by the obese (ob) gene and acts on receptors in the hypothalamus to regulate food intake and energy balance. The identification of leptin and its receptor mRNAs and proteins in human and mouse endometrium and placental trophoblast has attracted attention to the potential role of leptin in implantation. Thus, the aim of this study was to compare the expression levels of porcine leptin mRNA and protein in endometrium and myometrium during mid- and late-luteal phases of the oestrous cycle (days 10 - 12 and 14 - 16) as well as during two stages of pregnancy respondent to the beginning (days 14 - 16) and the end (days 30 - 32) of the implantation process, and in trophoblast during both periods of pregnancy. Leptin gene and protein expression in myometrium, and leptin mRNA expression in endometrium was more pronounced in the mid- and late-luteal phases of the cycle in comparison to studied periods of pregnancy, whereas leptin protein concentration in endometrium was either enhanced on days 30 - 32 of pregnancy in relation to days 14 - 16 of the cycle or there were no changes between pregnancy and luteal phase of the cycle. On days 30 - 32 of pregnancy, expression of the leptin gene in the endometrium, and of the leptin gene and protein in the myometrium was more pronounced in comparison to the earlier stage of pregnancy. Moreover, leptin gene expression in porcine trophoblast increased during the beginning of the implantation process compared to days 30 - 32 of pregnancy, while the protein concentration decreased on days 14 - 16 of pregnancy. In conclusion, the finding of leptin gene and protein expression in porcine endometrium, myometrium and trophoblast indicates that locally synthesised leptin can participate in the control of pig reproduction. The fluctuation of the hormone concentration during pregnancy and changes in its level between pregnancy and the oestrous cycle may indicate leptin's involvement in the implantation process.
