The focus of this article is to provide informations about soil enzymatic activity as a biological indicator for impacts of pesticides on soils. In this experiment, an ecological soil was treated with two types of fungicide (Ridomil Gold and Bravo 500) and two of insecticides (Mospilan 20SG and Vertimec 1.8% EC). The pesticides were assessed for their effect on different enzymatic activities. They were administrated over a 28 days period and the samples of soil were taken once every 7 days and analyzed in the laboratory. For each sample was determined the enzymatic activity, pH, humidity. The enzymatic activity was assessed using colorimetrical methods. Enzymes chosen for this study were cellulase, amylase, xylanase, urease, alkaline and acid phosphatase. Results shown that the enzymatic activity can increase or decrease when the soil was treated with the fungicides and insecticides chosen for this experiment.

This research focused on finding the best method for seed in vitro germination in Lavandula angustifolia and optimizing the medium for plant propagation. Seeds were sterilized and subjected to various treatments to break dormancy, then placed on half-strength MS (1/2MS) or distilled H2O + phytagel. Germination percentages were assessed and plantlets propagated on MS without growth regulators or with zeatin (0.5, 1, 2 mg/l), 1 mg/l BA + 0.5 mg/l IBA, 2 mg/l BA + 1 mg/l IBA or 3 mg/l BA + 1.5 mg/l IBA. After 8 weeks growth parameters were recorded and plants were acclimatized. Immersion in 20 mg/100 ml GA3 solution for 24 hours at 4°C was the most effective in breaking dormancy. Stratification at 4°C for 8 weeks and soaking in a solution of 0.5% H2O2 at 23°C for 24 hours also proved beneficial but to a smaller degree. Half-strength MS was the best germination medium. Shoot development was the highest in MS supplemented with zeatin (2 or 1 mg/l) while roots formed only in the control. Callus induction percentage was best in the presence of 3 mg/l BA + 1.5 mg/l IBA but decreasing concentrations increased callus weight. Plant acclimatization was more successful in moss:sand - 1:2 than in vermiculite:perlite:sand - 2:2:1.
本研究旨在寻找薰衣草种子离体萌发的最佳方法，并对植物繁殖的培养基进行优化。对种子进行灭菌，并进行各种处理以打破休眠，然后放置在半强度MS (1/2MS)或蒸馏H2O + phytagel上。在不添加生长调节剂或添加玉米素(0.5、1、2 mg/l)、1 mg/l BA + 0.5 mg/l IBA、2 mg/l BA + 1 mg/l IBA或3 mg/l BA + 1.5 mg/l IBA的培养基上进行繁殖。8周后记录生长参数并进行驯化。在20 mg/100 ml GA3溶液中浸泡24小时，在4°C下打破休眠最有效。在4°C下分层8周，在23°C的0.5% H2O2溶液中浸泡24小时也证明是有益的，但程度较小。半强度MS为最佳萌发培养基。在添加玉米素(2或1 mg/l)的MS中，茎部发育最高，而根只在对照中形成。BA浓度为3 mg/l + IBA浓度为1.5 mg/l时愈伤组织诱导率最高，但浓度越低愈伤组织质量越大。苔藓:沙子:1:2比蛭石:珍珠岩:沙子:2:2:1的植物驯化更成功。

The effects of dietary extruded linseed (ELS):walnut meal (WM) mixture (8:1) on performance and plasma protein profile in weaned piglets was evaluated for 21 d. Topigs piglets (n=40; BW=8.02±0.82 kg), age 30±3 days, were allotted into 2 groups and fed 2 diets: control [C, based on corn-triticale-soybean meal (SBM)] and experimental (ELS:WM, where the ELS:WM mixture (8:1) partially replace SBM). Blood samples were collected at 7d and 21d after weaning. The plasma protein profile (total protein, total bilirubin, albumin, creatinine, uric acid, urea nitrogen-BUN) were determined by a chemistry analyser. Dietary ELS:WM mixture improve the BW (P=0.047) and ADG (P=0.036) of piglets at 21d after weaning vs C, whereas ADFI and F:G ratio were increase (P>0.05). The plasma protein profile of piglets fed dietary mixture was not affected at 7d and 21d after weaning, except plasma BUN concentration that was decrease (P=0.027) at 21d after weaning. Lower BUN concentration indicated higher availability of dietary nitrogen reflected in a higher deposition of protein. We concluded that dietary ELS:WM mixture improve piglets performance and positively afect plasma protein profile, especially BUN in weaning period.

Bee bread is a product of the hive obtained from pollen collected by bees, to which they add honey, digestive enzymes and subsequently is stored in the combs. Increasing evidence suggests bee bread’s potential therapeutic benefits, including antimicrobial properties. Bee bread is characterized by a bactericidal and bacteriostatic activity. The current study was carried out to test the antimicrobial activity of bee bread extracts, in various concentrations, against the bacterial strains: Bacillus cereus, Staphylococcus aureus, Escherichia coli, Salmonella enterica and Pseudomonas aeruginosa. The results of this study indicate that the first two dilutions of bee bread extract, respectively 33% and 16.66%, showed higher antimicrobial activity and the other dilutions had a lower, but visible activity depending on the pathogen on which they are tested. The best antimicrobial activity was manifested on the Staphylococcus aureus strain, where all dilutions had an inhibitory effect both at 8 hours and 12 hours.

Food additives are substances of natural or synthetic origin, which are added to foods to serve a certain technological or sensory function, for example, to counter food perishability and bacterial degradation, give or restore color or impart flavor to foods.These additives generally provide some type of benefit for the food producer, processor or consumer. For example: acids that may be added to prevent the growth of microorganisms that cause spoilage may also prevent the growth of microorganisms that can cause foodborne illness. Some additives are directly added to food and ingredients, while others are added indirectly through contact with packaging materials as are, for example the preservatives BHA and BHT on the inside of breakfast cereal bags.The benefit of some food additives is enhancing health status or prevents disease; most benefits reflect economic considerations for food processors and sensory attributes and convenience for consumer.

The objective of this study was to evaluate the effect of a plant mix (bilberry, black currant, quince, peppermint and fennel essential oil) inclusion into the diets of piglets (18-45 kg) on intestinal microflora equilibrium. An experiment was performed on 8 castrated hybrid TOPIGS (18.69±1.25 kg) divided in 2 groups (C and E). The piglets were kept in an experimental house in individual metabolic cages. Compared to the conventional diet (18% crude protein and 3214 kcal/kg metabolic energy) of group C, the diet of E group had included 789 mg mixture of plants/kg feed. At the final of the experiment the piglets were slaughtered and digesta samples were collected from jejunum and ileum for microbiological analysis. For jejunum, a significant (P<0.05) decrease of Staphylococci spp. (log10 CFU/g) concentration in E group was noticed correlated strongly negative with a statistically significant (P<0.05) increasing concentration of Lactobacillus spp. (log10 CFU/g) concentration. The results were similar for ileum. This dietary mixture of plants had some effects on microbial population of piglets’ jejunum and ileum to help positively the intestinal changes of microbiota.

This research proves the economic effect of Calving Care performance in dairy cow feeding, on Holstein Friesian cows. Group M1 / 2014 of 10 cows in second lactation are the control group in which Calving Care was not administered, monitoring performances throughout the lactation of 2014. Group E / 2015 is the experimental group, where the same cows receivedCalving Care 300 g / cow / day, 21 days before calving. Dietary cation-anion difference was -15.28 mEq / 100 g dry matter. Group M2 / 2016 was the second control group, without Calving Care, productive performance in the following lactation was monitored.After calving, each cow has been monitored for Fat corrected milk (FCM) production per 305 days lactation and dry matter intake, ratio between these parameters being expressed asmilk production efficiency. Milk efficiency was 1.25 in Group M1/2014, 1.3 in Group E/2015 and 1.28 in Group M2/2016 respectively.

Sheep farming always made a special contribution to the development of practicing people, improving the standard of living, effects also known by Romanians, even if the number of sheep and implicitly the amount of wool had fluctuations over time. After the 90s, demand for wool in the textile industry began to decline and the wool has not been widely capitalized in Romania, being abandoned by farmers, even burned. The aim of this study is to provide solutions for wool collection in an organized manner and as profitable as possible for Romanians at national level, avoiding wool waste and chaotic export. The collection centers are unevenly distributed accros the country and there are some counties where sheep wool is not collected. With the proposed solution of locating other collection centers or distributing the authorized ones, it is possible to capitalize the entire wool resource available in Romania.

Sunflower meal with 3 mm particle size (SFM) with 66 or 80% moisture content was inoculated with 1x107 cfu (colony forming unit/g) of Bacillus subtilis ATCC PTA-6737 and fermented for 0, 24, 48 and 72 h. The pH was increased from 5.75 to 9.1 of SFM fermented at both moisture levels with no significant changes in organic acid production. The bacterial growth was peaked at 24 h. Dry matter and crude fibre contents of SFM decreased by 10-13 and 18%, respectively. In contrary, the amount of crude protein, crude ash and soluble amino acid nitrogen increased by 36, 61% and 145%, respectively, with no regard to the effect of moisture content. Phytic acid was degraded up to 42% at both level of moisture content. In conclusion, SFM was enriched with ash and protein and lowered in fibre and phytic acid contents, and can be used as alternative feed material in animal nutrition.

In conclusion, SFM was enriched with ash and protein and lowered in fibre and phytic acid contents, and can be used as alternative feed material in animal nutrition.","PeriodicalId":9587,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca.

Many plants and their constituents (carotenoids, flavonoids and other phenolic compounds), action to inhibit the free radical by the use of antioxidant activity, helping to a better efficiency of nutrients utilization. The purpose of this study was to investigate the antioxidant activity and phenolic content of five different plants, known for their antioxidant potential. Total phenols were determined by FolinCiocalteumethod, with few modifications. The antioxidant capacity was evaluated by DPPH, ABTS radical-scavenging activity and phosphomolybdenum method. The results showed that the highest antioxidant activity was obtained for walnut leaves in terms of ABTS evaluation and for bilberry leaves by DPPH and phosphomolybdenum methods. In the present study, peppermint, walnut and bilberry leaves proved to have an important antioxidant activity and also a total phenolic content.
