The study was conducted to evaluate the proportion level of insect antigens and its effect on goat immuno-response by detecting the immunoglobulin serum level. Twenty-four young goats were used in this experimentmaintained in traditional farms without health control. The animals were divided in threegroups,respectively control group (0µ AgG/L) and the others were treated with 0.5 ml of antigen-G by subcutaneous injection which had a concentration of 100µ Ag-G/L). The parameter observed was the serum immunoglobulin level. The mean value of serum immunoglobulin level between treated and control groups were compared by t-test. There was a significance different of parameter between groups observed (P

This scientific paper aims to present a detailed analysis of sheep breeding sector in Romania for the period 2000-2014. The data presented here were collected from various official sources and specialized publications and they revealed a decrease in the sheep livestock in the first period analysed(2000 – 2006), followed by a sustained growth until now (2007 – 2014).Meat production was relatively constant because the behaviourof the Romanian consumers towards for this aliment is determined by the Orthodox tradition during the Easter. Milk production had a course inversely with the evolution of the sheep livestock. The wool production, in this period, recorded an almost total loss of economic value.

In the last years and especially after the country's integration into the European Union the number of organic producers and the organic area grew at a rapid rate in Romania. The driving force for the developing of organic sector in our country is represented by the export market and the payments for organic farming system which are an important foundation for the financial performance of organic farms.The aim of this study was to analyze the evolution of organic farming system in Romania, with special reference to the area of organic land, the number of organic operators, the use of organic land and the organic livestock. The results of study showed that the total area of organic land in our country in 2014 it was 289.252 ha which is higher with about 58% as compared with that existing in 2010 which represent 2.22% of the total utilised agricultural area. As regards the use of organic agricultural land, it was found that in 2014 the largest part of them, namely 63.6% were occupied with arable land, 33.1% with permanent grassland and 3.1% with permanent crops. This study shows that in 2014 there were 14,470 operators in organic farming system and the main activities in the organic sector at farm level are the organic crops and rearing of organic animals.

This paper presents RSC characteristics regarding heritability parameter for the development, reproduction and milk production at the Pantelimon and Afumati farms. The milk production is the main target when we follow the goal of milk production exploitation from those two farms. To determine the heritability of morphologic characteristics and capability for the mechanic milking, it is obvious the milk cows from the group of study have a level of genetic determination for waist between 43% at Pantelimon farm and 35% at Afumati. So, they are fitting under variability limits of heritability coefficient. A higher heritability value to the entire population in this study is the height at the croup character. At the Afumati farm it was h2= 0.49 and at Pantelimon farm h2 = 0.47. The milking speed represents the most important parameter to reflect the capability of the udder for the mechanic milking, the heritability coefficient being between 28% and 48%, results obtained also by the other authors. The heritability coefficient determined for the Calving interval (CI) indicate a weak genetic determination, so, at the Pantelimon farm h2 = 0.195 and Afumati farm h2 = 0.110. The heritability of the between birth and the service period (SP) has lower values, between h2 = 0.140 at Pantelimon farm and h2 = 0.100 at Afumati farm. The heritability coefficient of milk production 0.31 - 0.35 and the fat percent was 0.48-0.51. So, at the both farms, we obtained data can be compared with similar data from the profile literature.

In order to study the effect of the intermittent light at adult quails after the peak of laying was organized an experiment on a total of 450 quails divided into two batches: a lot has been subjected to continuous illumination with photoperiod duration of 16 hours daily (control group), and the other lot has undergone a lighting program divided according to the following scheme: 10 hours light (natural), 2 hours darkness, 6 hours light (artificial) and 6 hours darkness. The duration of the experiment was 16 weeks and at the beginning of the experiment quails had 29 weeks of laying. From the research, it was found that the quails from the experimental group registered an average laying percentage high with 16.16% and average production per head with 18.89% higher compared to the control group. The average live weight was higher with 19.61%, and average egg weight was 18.89% higher compared with the control group. Weekly average mortality was 1.11% higher in the control group. Also, the average daily consumption of compound fodder has been about 12.32% higher; in exchange specific consumption was lower with 6.96% at the experimental group compared with the control group. Given the superior performance recorded in case of experimental batch, it is recommended to use asymmetric fractionated lighting system at quails in the period after laying peak.

In order to study the impact of a lighting program with asymmetric time intervals and different densities during the finishing period of youth quail for meat and slaughter results of youth male quail from population of Balotești in the period 28 – 49 days of growth was organized an experiment on a total of 300 male. At the age of 28 days were divided into cages for youth quail in two batches: the first batch consisting of 150 males has undergone a program of continuous photoperiod lighting with 16 hours per day (lots B and D), and the second batch has undergone a program of lighting with asymmetric time intervals with duration of 16 hours per day (10 hours light + 2 hours dark + 6 hours light + 6 hours dark) (lots A and C). Also, in the two batches was tested the effect of an experimental density of 250 cmp /head comparative with a control density of 125 cmp/head (lots B and D). From researches it is established that the best performances were recorded at the males from the batch A, who were subjected to a lighting program of 16 hours with asymmetric time intervals and was applied the experimental density of 250 cmp/head. The average live weight at the age of 49 days was with 6.47 % higher at batch B comparative with the batch A, with 9.21 % at batch C and with 13.71 % at batch D. Also in the batch A was registered the largest average carcass weight at age of 49 days (with 6.25 % from the batch B, with 11.02 % from the batch C, with 15.85 % from the batch D). Considering that have been registered superior performance at batch A is advisable when quail males are raised in the direction of meat production to be used a lighting program of 16 hours with asymmetric time intervals and a lower density of males in the cage because it significantly influence growth and slaughter performance.

The paper tried to make a connection between the lunar phases and the bovine conception rate both in dairy and beef farms. The goal of the study was to improve the efficiency of farming by sparing semen doses used for a successful insemination. 1481 pregnant cattle from seven different areas of Romania were the subject of this study. New moon and waxing crescent vs. full moon and waning crescent were associated with the insemination process. In one farm hormonal timing was used for inducing heats. In the others farmyards the oestrus was marked by spontaneous behaviour changing. The results confirmed a small influence of the lunar phases on the conception rate. The score was tight proportionally with the number of subjects. However the full moon offered a higher number of gestations than the new moon. The cows with hormonal timing heats offered a better connection between the lunar phase and fertility. Further studies could be done in this direction.

The aim of this paper is to highlight the importance of having a good control of incubation factors of ducks because they are the key in obtaining high technological and economical results in duck husbandry. Incubation factors can be divided in two great categories: 1. reproduction factors (mating system, the technologies used in duck husbandry genetic quality of the birds, sex ratio in the flock, the age of the birds, etc.); 2. incubation factors (egg collection, egg storage, preheating, incubation temperature, humidity, ventilation and movements of the eggs). Having a very firm control of this factors, one can achieve good incubation results which, later, can be translated in to bigger production of meat (and secondary productions) and bigger income for the farmer.

The hydrotechnic works often generate aquatic ecosystem disturbances. Sometimes they are local and short-term, but sometimes they cause significant long-term impact that may be irreversible. The present paper aims to analyze the possible impact of the maintenance works performed on Bastroe channel fairway on the populations’ dynamics of migratory anadromous fishes, sturgeon. The methodology implied sturgeon tagging and migration monitoring using ultrasonic telemetry technique during 2011-2014. The tags were inserted into the abdominal cavity through a simple surgical intervention, being set to transmit data related on swimming depth and water temperature towards receiver stations fixed on Chilia branch, upstream and downstream of Bastroe channel, Tulcea and Old Danube branches. The results showed that the distribution of the adult specimens during migration on Chilia and Tulcea branches was 53% - 47% (spring 2012/2014) and 31% - 69% in autumn 2013. A possible progressive warping of the Old Stambul and especially Musura branch, as well as an increase of the naval traffic on Bastroe channel will have major negative effects on upstream sturgeon migration for breeding.
