Prunus domestica L. is one of the tree fruits threatened by Plum pox potyvirus (PPV), a quarantine disease that causes fruit loss to plums and other stone fruits. HoneySweet is a plum tree created to be resistant to this virus. Beside genetical determinations, chemical composition and nutritional value are important for a future acceptance in the cultivation of this type of fruit trees. Two conventional (Renclod Althan and Stanley) and one genetically engineered (HoneySweet) plum fruits were evaluated for the nutritional value determination. The analyzed samples showed nutritionally valuable features. HoneySweet variety had a balanced content of individual carbohydrates. The total lipid content had values quite close to the HoneySweet and Stanley varieties, far superior to Renclod Althan variety. HoneySweet transgenic plum had the highest total protein content. Also, HoneySweet variety is distinguished by a balanced protein and lipid content. By comparing the three analyzed varieties from the perspective of the most important physic-chemical nutrients (carbohydrates, proteins and lipids), the highest nutritional value was registered in Stanley variety, closely followed by HoneySweet, and then by Reine Claude d’Althan.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

The bioproducts were formulated as concentrated aqueous suspension, each containing one of the following plant beneficial bacteria: Bacillus safensis Rd.b2, Bacillus spp. 75.1s and Cp.b4 strains. These were applied on potato seeding material in order to evaluate plant growth promotion effects. The biocontrol efficacy was also evaluated, using Rhizoctonia solani DSM 63002 as plant pathogen, and Prestige 290FS as reference chemical treatment.In the plant growth-promotion experiments, several biologic parameters were biometrically evaluated. Best results regarding plant growth and vigor were obtained using CropMax, a commercial phytostimulatory product. However, the bacterial treatment with Bacillus spp. Cp.b4 and 75.1s showed an improved plant growth compared to the untreated control. An efficacy of 93.75% against Rhizoctonia dumping-off was registered when using the Prestige 290FS chemical control. Mix treatments based on this pesticide, in low dose, combined with Cp.b4 or 75.1s biocontrol strains significantly reduced the pathogenic attack, showing 85 to 87.5% efficacy.The present research demonstrated that the bacterial bioproducts based on Bacillus spp. 75.1s and Cp.b4 strains increase plant growth and are highly effective in controlling Rhizoctonia attack in potato plants.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

There was a marked decrease in pH with 85% moisture content, associated at higher organic acid production, compared to increased pH at 24 h with 78% moisture content and a gradual decrease hereafter. Bacterial growth peaked at 48 h with both moisture contents. Fermenting SBM increased crude ash level by 65%, soluble amino acid nitrogen by 2.7 folds and degraded phytic acid by 65-75%. Moreover, there was a high level of organic acid production despite of decreased crude protein by 6-7%, but the effect of high moisture level was more pronounced in all case. In conclusion, fermentation SBM with water content of 85% at 35 oC by B. subtilis provided SBM an appreciable amount of bio-functionalities such reduced phytate content, increased soluble amino acid content and more importantly fortified with organic acids. The fermented SBM can therefore be used an antimicrobial agent due to its high organic acid level in animal nutrition.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Research has been expanded to six consecutive lactations, period in which the followed objectives were represented by: quantity of milk sucked by lambs during lactation, the quantity of milk produced in each lactation period when the flock is located in the milking situation exclusively and the total quantity of milk obtained in each controlled lactation. The work methods used are accepted by experimental practice. During the period of lactation was used the control coefficient method; exclusively for milking period was applied the AT4 method respecting the technical specifications specified by the International Committee for Animal Recording. Also, to eliminate the influence of environment, age, nourishment and maintenance conditions, in each season the period was the same (May-September) and had the same conditions of nourishment, maintenance, sheltering etc. Statistical processing of obtained data at the end of evaluation of milk quantity consumed by lambs show that in first 28 days of suckling, Ţigaie breed sheep furnish around 42% from the total milk quantity consumed by lambs during suckling period. Based on this observation we could say that application of selection at sheep on the basis of lambs’ corporal weight at age of 28 days is more indicated and efficient. In case of appreciation of milk quantity gathered by milking could be observed the fact that face to maximum level reached in first lactation the total estimated quantity was higher with 29.29% in second lactation and after that gradually decrease and record negative values in the last controlled lactation. Effectuation of a rate between milk quantity consumed by lambs and milk quantity obtained after their weaning show the existence of a close rate, with the exception of first lactation when sucked milk quantity was higher with 15.8% face to level of milk production gathered by milking. Statistical processing of information highlighting that between the amounts of milk consumed by lambs in the suckling period, there have been significant differences for P<0.01 and for P>0.05. During the six controlled lactations the maximum milk production was recorded in the second lactation and was of 139.67 kg of milk, superior with 29.29% than level obtained in the first lactation and with 5.29% lower to the total estimated production for the third lactation.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Farms from three counties in Apuseni Mountains (Alba, Bihor and Hunedoara) were monitorized for milk production and other reproductive attributes. Age of first calving, service period, calving interval and natality were the parameters monitorized in the study to determine the reproduction trains in the area of Apuseni Mountains. Analyzing the obtained data regarding the average production of milk, lactation duration in the studied counties, it is found that: on total lactation, the largest production was obtained in Bihor county with 4815.26 kg (332.6 days), followed by Hunedoara county with 4796.40 kg (325.6 days) and Alba county with 4528.05 kg ( 321.4 days). The obtained results, which reflect the current level of milk production in Apuseni Mountain area, show that the studied cows have a real productive potential, the average of the lactation yields as well as its duration, being at the upper limit of the breed, according also to specialized literature data. Breeding activity was found to be good but can be improved. Due to the great importance of reproduction, the economic and productive performance of dairy farms requires careful attention to its planning and management.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.
