Different clinical and paraclinical methods were used to investigate some reproductive indices. In this work 42 Holstein cows, between 21 and 62 days in milk (DIM), were examined by rectal palpation (RP), vaginoscopy (V), endocervical (ECC) and endometrial (EMC) cytological exam. Cervicitis was diagnosed when the second cervical fold was swollen and prolapsed with or without reddening. Cytobrush technique and cotton swab technique were used to take cytology samples at 21-33 DIM (PMN ≥8%), at 34-47 (PMN ≥6%) DIM and 48-62 DIM (PMN ≥4%) and stained using Diff-Quick. The percentage of neutrophils in the uterus and the cervix as indicators of inflammation was determined. Also, for reproductive management it was used uterine histopathologial (HPT) exam in another 12 puerperal cows. Conventional microscopic examination of the tissue sections allowed visualization of histological changes such as normal structure, infiltrate of polymorphonuclear neutrophils (PMN), hiperemia, moderate acute endometritis, periferal hemorragies secundar to biposy and hemosiderosis. In total, 78.57% (11/14) of femals had a normal cervix and, after using cytobrush method it was observed that 5 from 14 cows had over 91.08% of PMN. The incidence of subclinical endometritis was recorded as 60.71% (17/28). Another conclusion is that cervical swab cytology is not a good method compared to cytobrush technique that is reliable. Using cytobrush the incidence of subclinical endometritis was recorded as 60.71% (17/28). Endometrial biopsy in postpartum dairy cows might be useful and accurate procedure for detecting existence and severity of endometritis.

Acetochlor is a widespread used herbicide in maize crops; however, the environmental risk of its residues in the soilplant system remains unknown. There was assessed the dissipation dynamics of acetochlor doses and its impact on residue level and microbial activity in soil over a season of vegetation. Since the herbicide was applied to the soil surface, its degradation varies as a dependence of concentration, soil type, pH, organic matter and environmental conditions. The field soil samples extraction in different imposed conditions of depths, time and herbicide application revealed a moving deeper of doses. The increased dose (80%+Rd) affects the persistence of acetochlor in the top layer by increasing its half-life from 14 to 17 days. Dissipation followed a first order kinetics. The diversity of soil microbial community changed after the introduction of acetochlor doses. An evident increase of bacteria and soil microorganisms was observed; however, fungal growth was prone to be inhibited. The higher concentration of herbicide was found to be safe, as well as the residues of acetochlor below maximum residue limits (MRL) at the end of maize crop season.

Being a plant with considerable agronomic qualities, soybean returns to farmers attention (Dencescu et al.,1982b; Ionescu, 1985). Indeed the new varieties have improved by characters: high production potential, quality and constantly over time (Gallais & Bennerot, 1992). In exchange for use of these qualities are needed informations about how to adapt plants in different ecological areas (Giosan et al., 1986). Given white luvicsoil in South the plant finds a good regime of sufficient rainfall and temperature (Ionescu et al., 1986; 1994). Against this background proved to be important the specific crop system. 2.0-3.0 t.ha-1 yields were obtained while during the filling of the grains fell 150-200 mm water. During the growing season of 100-140 days have accumulated 1200-14000C temperatures above 100C. Among during the growing season and grain production achieved a positive correlation (r=0.591***) so that varieties with higher period during the growing season formed the best production. Plant morphology: size, number of pods per plant and grains were positively correlated with grain yield. Negative correlations were obtained between the thousand grains weight-TGW with production of grains, TGW with grain number per plant and between fat content with the content of crude protein of the grain. Production levels achieved over the years has been between 1.06 and 3.49 t.ha-1 like limits. Among the crop items highlighted technological density peaks at 60-80 seeds.sq.m-1.

Conservative soil tillage (minimum tillage and no-tillage) are considered among the most important components of conservation agriculture. Their research and extension was imposed especially in hilly areas with specific problems of desertification (erosion, drought) as bioremedial measures. Our research follows the effects of the three tillage systems: conventional systems, minimum tillage and no-tillage on soil properties (bulk density, penetration resistance, temperature and moisture, soil respiration) and on the production of wheat, maize and soybean, obtained on an Argic Faeoziom from the Somes Plateau. Average soil bulk density grows, compared to the conventional system (1.20-1.24 g/cm3), in all variants with minimum tillage (1.22-1.32 g/cm3); the highest growth is recorded at no-tillage, being 1.35- 1.38 g/cm3 with statistically significant positive differences. Soil moisture increases in all variants with minimum and no-tillage with different percentages, ranging from 1-15% v/v, compared to the conventional system. This is also reflected in the values of resistance to penetration. Tillage appeared to affect the timing rather than the total amount of CO2 production: the daily average is lower at no-tillage (315-1914 mmoles m-2s-1), followed by minimum tillage (318- 2395 mmoles m-2s-1) and is higher in the conventional system (321-2480 mmoles m-2s-1). Productions obtained at minimum tillage and no-tillage did not have significant differences for the wheat culture but were higher for soybean. The differences in crop yields were recorded at maize and can be a direct consequence of loosening, mineralization and intensive mobilization of soil fertility

The EU produces more than 190 million tons of meat, milk and eggs. About 450 million tons of feeds/year are needed to support this production in the 28 EU member states. Research and innovation in animal feeding and in feed manufacturing technology are basic for the support of animal production in the EU, being the most profitable investment for this industrial sector. One of the problems with market demands regards the economic efficiency of the production, which involves diet formulations and choosing feed ingredients. Fibre-high feed ingredients can decrease the cost of feeding because of their lower costs compared to the conventional raw materials used in poultry diets. The paper reports the findings of a study on the effect of higher dietary crude fibre levels given to replacement pullets on their subsequent performance. A feeding trial was conducted on 240 Lohmann Brown pullets (9-16 weeks). The pullets have been assigned randomly to four groups (C, E1, E2, and E3), with 60 pullets per group, housed in an experimental hall under controlled environmental conditions. The diets for the four groups were characterized by 14.5% CP and 2800 kcal/kg ME. Compared to the diet for group C (5% fibre/kg compound feed, CF), the experimental diets had different levels of dietary fibre, given by the different amounts of dietary alfalfa: 6% fibre/kg CF (E1), 8% fibre/kg CF (E2), and 10% fibre/kg CF (E3), in combination with 2 enzymatic products that improve fibre digestibility (Biozim M6000 and Digestarom). The production parameters (feed intake, body weight, weight gain and animal welfare) were monitored throughout the experimental period. The experimental results have shown that feeding pullets (9-16 weeks) with compound feeds high in fibre (6% - E1; 8% - E2 and 10% - E3), didn’t affect the growth parameters. The positive results compared to group C were recorded for group E2 (8% dietary fibre). The average live weight of E2 pullets (1419.5±97.76g GV) was significantly (P≤0.5) higher (by 4.65%) compared to group C pullets (1356.33±110.64 g LW). The live weight of E2 pullets also was 6.73% higher compared to the values stated in the Lohmann Brown management guide (1330.00 g LW).

The study used 96 day-old Cobb 500 chicks, weighed individually and housed in an experimental hall with 320C constant temperature and 23 h light regimen. During the starter stage (1-14 days), all chicks received a conventional diet formulation with sodium monensin (50 g/kg premix). During the growth stage (14-35 days), when the actual feeding trial started, the chicks were weighed, assigned to three groups (32 chicks/group) and housed in the same experimental hall. Throughout the experimental period, the temperature was maintained at 320C, humidity 36%, 23 h light regimen. Like in the starter stage, the chicks had free access to the water and feed. Compared to the diet formulation for the control group (C), conventional formulation, with monensin in the premix, the formulations for the experimental groups included 2% dry oregano (E1), or 2% rosehip powder (E2), but no monensin in the premix. Throughout the experimental period were monitored the bodyweight and the intake. At the end of the feeding trial, 6 chicks from each group were slaughtered in order to make measurements of the relative weight of carcass cuts and internal organs of broilers. Samples of intestinal content were collected for bacteriological assessment (determination of the Enterobacteriaceae, E. coli and Lactic acid bacteria). Throughout the entire experimental period (14-35 days), the average daily feed intake was significantly higher in group C than in groups E1 and E2, but the average daily weight gain and the feed conversion ratio were not different among the three groups. The dietary phytoadditives given the broiler chicks reared under heat stress (320C) had a favourable action in maintaining the health of the intestinal tract, by preserving the balance of the populations of microorganisms colonizing the intestine. Throughout the experimental weeks under heat stress no mortalities were recorded in any of the three groups.

Recently, kiwifruit consumption increased significantly, having in view its high nutritive and medicinal values. As consequence, the development and expansion of the kiwifruit industry has led to an increasing need for propagation material. The kiwifruit can be efficiently propagated under certain circumstances (proper substrate, hormonal rooting treatments) by hardwood cuttings, the most accessible methods for vegetative propagation for many horticultural crops. Our study presents the results of investigations on the effects of some rhizogene treatments (Radistim, naphtylacetic acid (NAA) 2000 ppm, beta-indolyl butyric acid (IBA) 2000 ppm and a mixture of NAA+IBA 1000 ppm) on root performance of hardwood cuttings for Actinidia deliciosa (AD20, Hayward, Katiuscia, Kramer, Tomuri) and Actinidia arguta (Francesca, Jumbo) species grown on a substrate composed from sand and perlite. It was developed a bifactorial experiment where "a" factor was kiwi cultivar/hybrid and "b" factor was the applied treatment represented by different rhizogene compounds. The efficiency of hardwood cutting under various hormonal rooting treatments was quantified by rooting percentage, number of formed roots, roots lengths (cm/cutting). The best rooting parameters were found when NAA+IBA 1000 ppm solution was used for Actinidia deliciosa (Hayward): rooting percentage was 73.1%, number of formed roots 17.2 and root length was evaluated as 19.3 cm/cutting.

The shell and head of shrimp is a waste material whose protein content is constrained by its content of chitin (15-20%) making it difficult to digest. The objective of this research was to determine the optimum time required for different microbes bioprocess shrimp waste in order to improve nutrient availability, protein digestibility, and metabolizable energy of these materials in native chickens. Experiments were conducted using a completely randomized design with three microbial treatments and bioprocessing times. Data were statistically analyzed for variance using a Duncan’s Multiple Range test. Shrimp waste materials were treated with each microbe sequentially over time (W) as follows: W1, Bacillus licheniformis (Bl) + Lactobacillus sp. (Ls.) + Saccharomyces cereviseae (Sc), each for 1 d; W2 = Bl+ Ls+ Sc, each for 2 d; W3 = Bl+ Ls+ Sc, each for 3 d. Bioprocessed products of shrimp waste materials were used as a nutrient concentrate in diets of native chickens (crude protein). The optimal crude protein content at W2 of the bioprocessed product was 48.5%, while extract ether, calcium, and phosphorous levels were 7.81%, 7.57%, and 3.14%, respectively. The highest protein digestibility obtained from the best nutrient (W2) with value 72.91%; the best of metabolizable energy of these materials was 2613.90 kcal/kg.

Listeria monocytogenes is a Gram-positive, psychrotropic, facultative anaerobic pathogen and it is the etiological agent of listeriosis, a severe foodborne disease of major public health concern. Listeria monocytogenes has high ability to adapt adverse condition. Therefore, the control of Listeria monocytogenes in foods and feeds is very difficult. N this purpose, organic acids and bacteriocins have been used for many years in preservation of foods against pathogen contamination. In this considering, it was aimed to determine the effects of bacteriocin, organic acid, and mixtures of them on the Listeria monocytogenes in this study. Feeds were divided into six experimental groups that consist of control, 150 mg/kg bacteriocin (B150), 300 mg/kg bacteriocin (B300), 3g/kg organic acid (OA), 150 mg/kg bacteriocin + 3 g/kg organic acid (B150+OA) and 300 mg/kg bacteriocin + 3 g/kg organic acid (B300+OA). Listeria monocytogenes cultures were added by spraying on feed samples in sterile bags and were counted by inoculating onto agars at 0, 7, 15, 21 and 28 days. At the end of this study, bacteriocin and organic acid supplementations have been found to have positive effects on Listeria monocytogenes contamination. But the best antilisterial effects was achieved by combined use of bacteriocin and organic acid.

Experimental trails have been conducted between March 2010 and January 2012 in Gerlengec village of Biga District situated in Canakkale Province, Turkey. In this study, control along with 5 kg N/ha 4M (chelate organo-mineral fertilizer, 5-10-0), 10 kg N/ha 4M, 5 kg N/ha composite (20-20-0) and 10 kg N/ha composite of five different types and doses of fertilizer were used. Height of the grass has been increased from 10.0 cm to 110.9 cm and 22.8 cm to 113.1 cm in 2010 and 2011, respectively by increasing the grass layer of the rangeland from 1st March to 30th May. At the same time, the fodder production has been increased from 84.0 kg/ha to 494 kg/ha and 95.8 kg/ha to 631.1 kg/ha in 2010 and 2011, respectively. An increase, both in the grass layer height as well as the fodder production has been accelerated between 10 to 20 April. The application of fertilizers has none significant level of affect to the grazing maturity time of rangeland. The effects of fertilization on legumes in rangeland were important in general while its impact on the species of grains and other related families has mostly been appeared in the months of summer and autumn. According to the two-year average results, legumes that found in plant vegetation were increased by the application of composite fertilizer while decreased due to 4M fertilizer. All of the fertilizers showed an increase in gramineae but reduced the species from other families. All types and doses of fertilizer showed an increase into the quality level of rangeland in each of two years, but an extreme increase of 10 kg N/ha has been occurred in those plots which were applied to 4M fertilizer. According to this, grazing should be started in 20th of April in similar rangelands and 5 kg of nitrogen should be applied to per hectare for improving the quality of rangeland.
