Raising Japanese quails for eggs and meat production has seen great development in recent decades because on the one hand of quail eggs and meat quality (rich and well balanced nutritionally, good taste), and the other hand due to natural medicine recommendations to consume these products with proven therapeutic effect. The aim of this paper was to determine the current average characteristics of incubation, the medium productive performances of youth and hens quails of egg-meat mixed population "Baloteúti", important population for raising quails in Romania and in witch is applying consistently an amelioration program. The research has established the following production data: the average percentage of hatching is 66.34 ± 0.22%, average weight is 8.94 ± 0.56 g at 1 day of age, and 210.45 ± 2.29 g at the age of 42 days, average gain between 1 and 6 weeks of youth raising is 201.51 g / head / period, average daily consumption of fodder during 1-6 weeks of raising is 19.85 ± 1.23 g. The average laying between 1 and 40 weeks of hens is 74.45 ± 1.03%, the average feed consumption during 1 to 40 weeks of laying is 32.25 ± 0.78 g, while the average yield at slaughter is 73.43 ± 0.44%. Productive characteristics of Balotesti quails such as: high weight of the chick at one day of age, fast-growing to 42 days, high performance at slaughter, average percentage of laying up to the age of 40 weeks of laying make this quail population recommended both for the eggs and meat production. An advantageous feature is that males resulting from sexing in using for egg production can successfully valorised for meat as complementary production. Remain to be improved the incubation results of this population by applying proper egg storage conditions (temperature, humidity), using the incubation technology and incubators being constructed following studies strictly conducted on quail eggs.

Increased competitiveness in the biological fish material market required the improving the quantitative characters of exploited species. One of the essential problems of heredity study quantitative characters is knowing the degree of hereditary transmission of characters from parents to offspring. Assessment of genetic determinism was based on heritability. This procedure requires knowledge of causal components of variance. The biological material studied consisted of 50 descendants of Ineu carp breed, who came from five mothers and ten fathers. Each descendant was measured for three characters: body weight, maximum body height and body length at the end of the first three summers of growth. For variance components analysis was used BLUP (Best Linear Unbiased Prediction) methodology, applied to an individual animal model. The results showed that the characteristics considered their genetic determinism is low to medium and medium to high. Thus, it was found that, after the first summer of growth, morphological characters measured have a low genetic determinism (0.1615; 0.1894; 0.1708). After the second summer of growth, body weight and maximum body height have medium genetic determinism and body length high genetic determinism (0.4426). After the third summer, weight and body length have high genetic determinism and maximum body height has medium genetic determinism (0.3270). In conclusion, genetic determinism of considered characters is low to medium, an aspect which leads to the conclusion that to maximize the effect of selection is necessary to consider family selection.

The hatching eggs disinfection it is a very important process of eggs hatching technology. The results of hatching process as well depend on the method of eggs disinfection before the incubation starts. Method of hatching eggs disinfection needs to be chosen in that way to improve the hatching eggs without harming pre and post development of poultry youth.Using of ultraviolet activation and different systems of magnetic fieldled to increase hatching index of geese eggs, better results of hatchability had the geese eggs after using magnetic field in system of permanent activation during 15 minutes and it was 75.3% in last experience or higher by 1.7% comparing with control group.Studding the embryo death during the hatching period there was established that the magnetic field used in permanent system during 15 minutes had a positive influence on this index and there was noticed the difference between first and control groups of 1.7 % for first group.Studding the number of received goslings of first quality there was noticed that it was higher in the second group wheresystem of split magnetic field was used during 10 minutes and it was higher comparing with control group by 4.2%.

Using mixes of herbicides and fertilizers we obtain synergic effects between the components of those compositions, which is materialized in superior crops compared to the crops obtained when these products are separately used. The mix of fertilizer – herbicide is very efficient on the mono and dicotyledonous weeds of the corn crops. As well, the toxicity of these mixes to mammals is moderate, pertaining to the toxicity group III.

The purpose of present investigations was to determine the hourly frequency of paddock exploring and social behavioral manifestations in dogs housed in a specialized shelter in relationship with the male-female proportion and animals mean age in the group, to improve the latter structure. Findings indicate that a lesser male number and a lower female mean age in the group significantly influence female paddock exploring behavior, in that where more females and fewer males were accommodated showed the highest hourly frequency of female paddock exploring behavioral manifestations (with an hourly average of 1.58 ± 0.19 of behavioral manifestations). Hourly frequencies of play and aggressive social behavioral manifestations of females were also affected, recording a female play behavior higher in the case of keeping them with fewer males, but also for a lower female mean age in the group (with an hourly average of 0.98 ± 0.12 behavioral manifestations). Also, a higher male number and a lesser female number in the group increase the hourly frequency of female aggressive behavioral manifestations towards others (with an hourly average of 1.10 ± 0.10 of behavioral manifestations). Also, it has been registered a higher hourly frequency of female food theft in groups where the male number was lower than female number, correlated with lower female mean age. Regarding the influence of female number on male paddock exploring and social behavioral manifestations, it is obvious that a higher female number in the group, also correlated with a higher male mean age, reduces male aggressive behavioral manifestations towards themselves but increases the hourly frequency of male aggressive behavioral manifestations towards others (with an hourly average of 1.50 ± 0.24 of behavioral manifestations).

A production cost means all costs for inputs consumption performed by the enterprise for goods and services produced and offered. Production costs are very meaningful about business quality and it is a decision-making condition for every producer; lowest cost level is the standard in choosing the right option. These researches were intended to give an overview about these problems. Objectives were first to find unit costs for feeds and kg live weight to broilers type Certificate and second to reduce unit costs by changing energy and protein content of feeds for these broilers. Experiment was performed with Ross 308 chickens, raised according to the technology to produce ecological poultry meat type Certificate. Three experimental variants were used; respectively three treatments/each variant and experiment design was in pens. Experimental period was of 56 days of age; feeding technology used was bi-phase, as following: group CM, with constant energy and protein level, group C1, with constant energy and variable protein level and group C2, with variable energy and constant protein level. Major production performances were checked and slaughtering was followed by cutting and finally all data were processed and read statistically. Finally unit costs per kg processed feed (1,308 – 1,362 lei) and per kg live weight (5,532 – 5,667 lei) were analyzed.
