Restriction fragments analysis was conducted post PCR amplification, and cleaved with HaeIII, HinfI, HhaI, MseI and SduI restriction enzymes. Differences in the lengths of the obtained amplicons were detected after gel electrophoresis, and restriction analyses of the PCR fragments led to identification of six out of eight isolates as belonging to fungi T. parceramosum/ T. reesei/ T. longi, Polyporus squamosus, Fusarium oxysporum and Trichoderma atroviride groups. The PCR ITS-RFLP molecular identification technique can be used successfully for routine screening of fungal isolates from various environments.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

The food conversion ratio was lower for the Guar 70 PFR and Guar 60 PF groups. Other authors reported that guar meal administered in low doses (2.5% and 5%) in feeds had no negative effects on the growth performances of broiler chickens, whereas higher doses (7.5 and 10%) negatively influenced both growth performances and broiler chickens’ health.

The presence of invasive species is often associated with acclimatization of new species of fish, activities correlated with the absence of effective control and quarantine programs. In other words, when new desired species are imported, other accompanying species are also brought in often in the form of embryonated eggs or juveniles.The brown bullhead, which we have studied, is also an invasive species of fish in Stejeris Lake, Cluj County. This species is of interest, both scientifically and economically. From the scientific point of view, brown bullhead has a high capacity of resistance to environmental changes, unfavourably conditions, which ensures a perpetuation of the species in almost every aquatic environment. Even though it is recognized that the economic impact of this invasive species is significant, not much information is available at present, and neither is there much data about the topography of its internal organs, which is being studied in this paper.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

The current economic importance of breeding Bucovina Shepherd dogs is very well highlighted by the fact that in the area of origin there appeared a number of kennels, in which selection programs and routed mating are applied in order to increase the quality of genetic material and to enhance the skills of this dog. From this point of view, we analyse the existence of genetic correlations between certain morphometric characteristics in Bucovina Shepherd dogs, and carry out a comprehensive study on some elements that make the difference among the four breeds of shepherd dogs raised in Romania. These endeavours are part of current concerns addressed in animal husbandry. Biological material subject to investigation was represented by the canine population belonging to the Bucovina Shepherd Dog breed, raised in the North-Eastern part of Romania. As a result of statistical data processing and interpretation, it was established that for most attributes, in the couples analysed, the correlation coefficient exceeds 0.400 which means, in general, that the analysed characteristics are well correlated. However, there are also weakly correlated characteristics (r< 0.2) as is the case of dorsum height and hip height. Instead, the correlation between the height of the base of the tail and back height was positive and intense (r = 0.98), which means that the selection applied for one of these two characteristics leads to the improvement of the other characteristic. Also, as a general conclusion of the study, the results could be applied in the improvement of this sheepdog population because the correlation coefficient values recorded between the main characteristics analysed have been statistically distinctly significant (p < 0.01%).","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Therefore, pelt quality assessment and studying of the mode of colour transmission are on-going activities for purposes of improvement. Lambs are obtained from the breeding of genitors belonging to the black colour variety. Breeding was based on matching pairs, involving 193 females, taking into account their line of origin and the pursued goal of the improvement. The appraisal method of transmission of colour and characteristics on which the quality of pelts depend was made in the first 24 hours after birth, based on the technical specifications and instructions in the certificate of origin, and productive values. Classification of lambs in relation to productive performances was done on the basis of the total final score. The study was conducted over a period of five generations of lambs obtained in calving seasons between 2010 and 2014. From the crossbreeding analysis of the genitors of black colour variety over several generations, it was established that 98% of the offspring had uniform black colour, but with different shades, and only 2% had other colours. This data allow us to conclude that the black colour specific of the Karakul of Botosani sheep is a dominant type.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

In this purpose, a number of 14 biological samples were collected from two breeds : Semigreu Romanesc and Lipitan. The genomic DNA was isolated from hair samples with Quick-gDNA Mini Prep kit, according to the manufacturer’s protocol. A 229 bp fragment, targeting the polymorphic region of GYS1 gene, was amplified with a set of specific primers and the PCR products were digested with HpyCH4 V restriction enzyme. The resulting fragments were separated in 3% agarose gel. Two fragments, of 151 and 78 bp, which correspond to the GG genotype, were identified, while four fragments (151, 97, 78 and 54 bp) were obtained in the case of heterozygous AG genotypes. All analysed Lipitan horses were homozygous for the G allele, while all Semigreul Romanesc horses were heterozygous, carrying the A allele which are associated with PSSM.
