In this study, were considered productive performance of juvenile Frăsinet carp, raised in intensive systems in a systematic ciprinicol farm. The inspection fishing activity carried out by an interval of about two weeks, at random, was body weight at different ages, and based on them, increase medium rais up. Also, main measurements were made tangible and corporal indexes have been calculated. Somatometric raw data were statistically processed and the following parameters were calculated: mean, standard error of the mean, variance, standard deviation and coefficient of variability. The summer I growth of populating, average weight of juveniles varied between 0.2-1.0 g/fish, and at the end of growth, fall, summer I juvenile has reached an average weight of 40-90 g/fish. Juveniles showed a good growth rate, according to the pond, the total average increase from populating the tanks until harvest fishing being 39.8-89.7 g/fish in 2009 (body weight increased by 199-299 times), 69.8-89.8 g/fish in 2010 (+349-449 times) and 74.0-89.0 g/fish in 2011 (+74 times). The main phenotypic features of summer carp Frăsinet, differs from the carp native populations, especially in relation to body length (total length and the standard 12.0 cm, respectively 11.5 cm,), the maximum height of the body (5.5 cm), high perimeter 11.5 cm, thickness trunk 5.4 cm, caudal of the peduncle length 3.7 cm. Except large trunk length and perimeter, the other body dimensions population analyzed is quite heterogeneous, as evidenced by the heritability coefficient values (13-28%). In first summer, the Frăsinet carp, demonstrated a correct conformation and a good body the proportionality of the optimal values of corporal indexes: 2% index of fattening, 2.1 profile index, 0.99 quality index, 47% index of thickness and 32.3% carnosity index.

Compared to known anatomical data, we appreciate that our observations underline certain particularities of the coronary arteries and their superficial and deep branches in the pig. The study was conducted in the Department of Comparative Anatomy of the USAMV Cluj-Napoca, in collaboration with the Department of Histology and Embryology of Veterinary Medicine Bucharest, on 4 pig hearts samples. The clinically healthy animals aged between 2 to 4 months were commercially slaughtered by bleeding. The hearts were collected with their vessels intact. Using step-by-step dissection techniques we have harvested the 4 hearts, and in two of them we have underlined the origins of the left and right coronary arteries to inject them with a coloring agent (PALUX and red pigment), and the other two hearts were harvested for histological processing. After injecting the coloring agent in the coronary arteries the two hearts were submerged in a 10% formalin solution over a period of 24 hours, to fixate. Histological processing comprised the following steps: sample harvesting, fixation, wash, dehydration, paraffin inclusion, cutting, paraffin removal, hydration, coloring, clarification and mounting. Aside from the deep branches of the superficial coronary arteries, both the paraconal artery, the circumflex artery and the right coronary artery give off direct deep branches for the myocardium and for all of the papillary formations of the atria and ventricles. The histological aspects of the left and of the right coronary arteries are. The elastic fiber density increases with age, and the fibers are more numerous in the external half of the tunica media. In younger ages, the coronary arteries have a muscular type aspect and they present a tendency to become musculo-elastic arteries along with the ageing. The elastin is produces by the smooth muscle fibers of the internal layer of the tunica media, but also by the fibers of the adventitia, situated at the border with the tunica media.

Avian reovirus infection is prevalent in intensive poultry farming, especially in broilers, wich evolve with many anatomoclinical forms. The researches was carried out in a flock of 10500 broilers,from Cobb hybrid. This flock was monitored until the age of 41 days, by clinical and anatomopathological exams, performed biweekly. The results were processed and graphically presented. The tests performed were identified following anatomoclinical forms of reovirosis: arthritis- tenosynovitis, ascites, hidropericard, proventriculus inflammation, catarrhal enteritis and necrosis of the femoral head uni and bilateral. Arthritis- tenosynovitis appeared at the age of 19 days maintaining in a relatively constant frequency until the end of the experiment. Ascites occurred at the age of 26 days with a frequency of between 12.5% and 20%. The hidropericard appeared at the age of 26 days, with a frequency between 12.5% and 42.85%. Catarrhal enteritis was reported at the age of 12 days, with a maximum frequency of 57.14%. Femoral head necrosis was signaled from the age of six days in both forms(unilateral and bilateral). Unilateral necrosis had a frequency of 42.85% at the age of 41 days and bilateral had necrosis has the frequency of 71.42% at the age of 21 days. The results obtained showed reovirosis evolution in broilers, in several clinical forms, confirmation of the disease was demonstrated by the polymerase chain reactionreverse transcriptase.

During the gestation period, canine females go through physiological changes which can influence the way the anesthetics are absorbed, metabolized and excreted. Furthermore, the pharmacokinetics of the drugs vary from mother to newborn. The drugs administered will pass through the placental barrier and carry across from dam to fetuses. For this reason, choosing the right anesthetic protocol for cesarean section can represent a challenge for a doctor, who has to keep in mind the well-being of both the dam and the fetuses. While choosing the anesthetic protocol to be used, the anesthetist will have to consider all of the above criteria, seeking to minimize the cardiological, vascular and neurological depression of the fetuses. The purpose of this paper is to discuss the different anesthetic protocols which can be used, and to assess the benefits, as well of the disadvantages that each of the available medications and methods can present. The options of anesthetic procedures being considered during the caesarean section in canines are represented by general anesthesia or local anesthesia combined with general anesthesia. Of equal importance are the preoperative assessment and the potential recovery time of the mother, which can influence the immediate maternal care given to the newborns.

Introduction: Due to the escalating antimicrobial resistance of numerous frequent pathogens, research on natural antimicrobial compounds is intensively published. One of the most in trend, yet controversial antibacterial natural products, is the Manuka honey. Manuka honey, produced from the Manuka (Leptospermum scoparium or Leptospermum polygafolium) tree, contains a unique antimicrobial factor (Unique Manuka Factor, UMF), which is absent in other types of honey. Aims: Commercial Manuka honey was investigated for assessment of antimicrobial effect against different Gramnegative and Gram-positive bacteria. Materials and Methods: Two types of Manuka honey with different UMF and one local polyfloral honey were assessed for antimicrobial activity against Staphylococcus sp., Streptococcus sp., Listeria sp., E coli, Salmonella sp. Pure broth cultures were pour plated on agar and incubated. Each type of honey was spotted in a marked place on the agar, pending the examination of inhibition areas after another incubation period. Results: Commercial Manuka honey has antimicrobial activity for Staphylococcus sp., E.coli and Salmonella sp., but not for Streptococcus sp. and Listeria sp. No antimicrobial effect was noticed for regular polyfloral honey. Conclusion: Using the described method, Manuka honey revealed an antimicrobial effect against Staphylococcus sp., E.coli and Salmonella sp., the intensity of which was directly proportional with UMF.

The ethanolic extracts of hawthorn (Crataegus monogyna) and dog-rose (Rosa canina) were found to contain polyphenols with antioxidant activity. The aim of this study was to assess the antioxidant properties of hawthorn and dog-rose polyphenols in linoleic acid emulsion model system, comparatively with synthetic antioxidant BHA. Polyphenols and BHA were incorporated in a linoleic acid emulsion at the final concentration of 100 ppm and then incubated at 80°C for 7 days. For determination of the progress of oxidation processes, primary and secondary peroxidation products levels were evaluated at every 24 hours. Hawthorn and dog-rose polyphenols inhibited the formation of lipid hydroperoxides, conjugated dienes and thiobarbituric acid reactive substances. The protective effect of hawthorn and dog-rose polyphenols was superior to the one of BHA synthetic antioxidant.

Honey is a natural food produced by bees from the nectar of flowers and is a mixture of carbohydrates, amino acids, enzymes, vitamins and many bioactive compounds. Due to its special composition, honey is a functional food with antibacterial, anti-inflammatory and antioxidant properties. Studies have shown that honey’s properties depend mainly on the vegetable source from which it is obtained, but also on the processing type and storage. This research aims to evaluate the antioxidant capacity of sunflower honey compared to meadow honey by assessing total phenolic content, total flavonoid content, total antioxidant activity, free radicals scavenging activity and reducing power. For the determination of total phenols and flavonoids, antioxidant capacity and reducing power, spectrophotometric methods were used. To assess free radicals scavenging activity, chemiluminometric methods were used. Meadow honey showed the highest concentration of polyphenols (143.29 ± 9.12 mg GAE / kg) and flavonoids (118.09±8.84 mg CE / kg). DPPH radical scavenging capacity was higher for sunflower honey (78.32 ± 5.11%) compared to meadow honey (45.12 ± 3.26%). The two honey types showed capacity to scavenge superoxide anion and singlet oxygen, with an inhibition rate of over 50%. In conclusion, sunflower honey and meadow honey presented important concentrations of polyphenols and flavonoids and the results suggest a relationship between honey type and total polyphenols and free radicals scavenging activity

ARTIFICIALLY FORCED FERTILITY IN DAIRY CATTLE EMBRYO TRANSFER

Published in Scientific Works. Series C. Veterinary Medicine, Vol. LXI

Forced increased fertility in cattle can be obtained by multiple ovulation embryo transfer (MOET). This paper presents results of a trial to shorten interval between two pollyovulation treatments to the term determined by the natural estrus shown by donors after the previous embryos’ collection. Pollyovulation was provoked using FSH. Experiment started with 4 Romanian Black and White heifers, 17 month aged, but only two of them answered to the treatment for estrus synchronization. Both these heifers have shown heat in the same day, at 11 days after uterine washing. A total number of 27 yellow bodies were counted (14 units in one heifer and 13 in the other), but only 12 embryos were collected (11 embryos from the first heifer and 1embryo from the second). There is no explanation of the fact. The resulted interval between pollyovulation treatments was 53 days, 7 days less than the 60 days interval recommended by literature. More interesting was the presence of a total 26 atretic follicles in the 4 days (diestrus state) of embryo collection. They must pertain to the first wave of follicles starting maturation after prostaglandin injection given at embryo collection to prevent pregnancy. The fact suggests the possibility to stimulate these waves of follicles to have shorter interval between pollyovulation treatments. It is counted that the interval could be shortened up to 25 days. If that is possible MOET could be applied in heifers to increase selection precision of mother of sire dams by progeny testing them. New idea is to use MOET in dams of known genetic merit to discover better compatibility of parental pairs to obtaining the wanted type of the breed. Experiments are needed also to establish if more frequent uterine washings cause or don’t cause alteration of uterine mucosa functions.

ASCOSPHEROSIS INCIDENCE IN BEES INVESTIGATED FOR MAJOR BACTERIOSIS IN THE BEEKEEPING YEAR 2016

Published in Scientific Works. Series C. Veterinary Medicine, Vol. LXIII, Issue 1
Written by Florentin Gheorghe MILEA, Ion RADOI, Agripina ŞAPCALIU, Vasilică SAVU, Ovidiu POPA

Ascospherosis is an invasive mycosis occurring in Apis melifera bees, caused by Ascosphera apis that affects the 1-5 days aged bee larvae of maximum receptiveness at the age of 1-2 days. From the total of 18 apiaries identified in the active-inactive season 2016 in which the evolution of mycotic diseases was diagnosed, the chalk brood was present as a morbid entity with unique evolution in 10 apiaries (55.55 %), stone brood evolved in 2 apiaries (11.11 %), and mycotic diseases of mixed evolution were registered in 3 apiaries (16.66 %), out of which suspicions of major bacterial diseases in one apiary (5.55% cases) and in 2 apiaries evolved together with internal and external parasitoses (11.11 %). Regional incidence of chalk brood places the south-east area on first place having over 2/3 of positive tests. Season incidence of the chalk brood shows that over 38.8 % cases presented it at the end of the beekeeping season, and in the inactive season months (January – February) the incidence is minimum (11.11 % cases). Complex laboratory tests in all the 18 apiaries diagnosed positively with mycotic diseases permitted identification of Ascosphera apis spores in the samples collected from live bees intestines, pollen, bee bread and brood combs. Bee colonies in the monitored apiaries (59.56 %), in which ascopherosis evolved and did not present clinical signs, may be deemed infestation sources.

Taxidermy is the art of dissecting and preserving animals as natural as possible, in order to exhibit them in natural science museums and in individual collections as trophies of the collectors or as decorating objects. In naturalization, minor surgical procedures for changing the mimics of the face are necessary in order to increase the value of the exhibits. The aim of the current work was to improve the technique of taxidermy in order to create valuable exhibits. Based on the bibliographic research and analysing the already existing pieces from different natural science museums and private collections, we noticed that technical improvements, especially of the facial region, were required in naturalizing the trophies coming from large mammals. The study was conducted on two deer heads. The naturalization was obtained by dissecting and removing the skin, excepting the ears, eye lids and oral cavity, where special procedures were required. The used method was systematic skinning. Tanning was made with eulan which insures a high flexibility and durability of the skin. The two prepared exhibits had an increased storage rate because there was no source of food for insects that could damage the material. With the improvement of naturalization technique of the exhibit, its storage life was also increasing. Application of new techniques of conservation and the use of new materials available in taxidermy, offers a long-term economic value to the exhibits in terms of structure and preservation of tissues.
