This study was carried out to estimate the trend components (the phenotypic, genetic and environmental trends) for 305-day milk yield in Holstein Friesian Cattle raised between the years 1989-2012 at the Ceylanpınar State Dairy Farm. In order to estimate the trend components 6165 lactation records of 2055 Holstein cows was analysed. It was found that the lactation period average was 313.23 ± 28.47 days, the annual average lactation milk yield was 6197.88 ± 1681.35 kg and adjusted 305-day lactation milk yield was found to be 6164.41 ± 1713.90 kg. In order to estimate of genetic parameters, standardized milk yield according to 305-day lactation period (lactation 1, 2 and 3) were analysed primarily with repeated-measured animal models by using MTDFREML programs. According to the data obtained in the study, the lactation length, average lactation milk yield and average 305-days milk yield adjusted were calculated as 313.23 ± 28.47 days, 6197.88 ± 1681.35 kg and 6164.41 ± 1713.90 kg, respectively. The phenotypic, environmental and genetic trends for 305-days milk yield were found to be -70.72 kg/year, -70.53 kg/year and -0.19 kg/year, respectively.

As a result of applying conventional agriculture that involves synthesis medicines, pesticides and GMO’s, the quality of food gave rise to concerns for the world population. In these circumstances organic agriculture has massively developed in the last decades. The features of this new type of agriculture were also used in aquaculture. Therefore, the European decision makers have issued the following legal acts: Regulations (EC) No 834/2007, 889/2008, 1254/2008, 710/2009 and 537/2009. As regulations they shall apply directly in the national legislation. These regulations cover the fields of pounds for aquaculture, specific organic feed and reproduction methods by organic genetic material. Another target of the regulations is the production of an important source of organic feed – seaweed - intended for the feeding of organic farm animals. In Romania the targeted species are the carp and the Asian carp varieties. There is a great potential for the seaweed organic feed. The organic aquaculture interferes in the friendly way with the environment maintaining the natural characteristics of it and also a sustainable agriculture activity.

Were investigated the exterior features on the basis of sampling and the calculation of the physique indexes of Holstein cows of Dutch and German breeding in the herd of Joint-Stock Company „Aydyn”, Comrat, Administrative and Territorial Unit Gagauzia, Republic of Moldova. Cows of German breeding in many measurements had superiority in comparison with contemporaries. A cow of Dutch breeding were significantly inferior to the peers of the German selection for high-altitude measurements - the height at the withers and in the sacrum was 2.6 cm (P˂0.05) and 2.0 cm (P˂0.01), respectively. The body in length was better developed at cows of Dutch breeding - according to the index of stretching; they exceeded the peers of German breeding by 2.1 %.

Organic farming is a sector of great perspective for Romania, due to the fact that it enjoys appropriate conditions for the development of such a system of agriculture, fertile soils and low level of pollution of the countryside, by comparison with the economically developed countries, where super intensive agricultural technologies are used extensively, based largely on chemical fertilizers and pesticides. According to some data from the Ministry of Agriculture and Rural Development, organic products market in Romania is in the full process of development and diversification. The aim of the present study was to analyse and interpret statistical data on the main crops, the evolution of cultivated areas, environment and ecological operators, the main genetically modified plants and the evolution of the areas cultivated with genetically modified organisms in the period 2008-2016 in Romania. Based on the statistical data of the plant sector, for the period 2010-2016, it is now taking shape that ecological agriculture was not a stable sector in Romania, having a constant evolution, in the years of study 2014-2016. Romania has great opportunities for promotion and development of organic agriculture due to the utilised agricultural area of 14.8 million ha and of the soils of unpolluted groundwater.

In the article are presented the results of studied animals of the Aberdeen-Angus breed by blood groups. The highest frequency of antigens B2, G3, Y2, G ', Q', G" (EAB locus), antigens C1, C2, E, W and X2 (EAC locus) was detected. There is a high incidence of allele B1G1 (0.0913), which is accessible to us from literary sources, is met only at Holstein cattle of the Yaroslavl breed and the red Estonian breed. The concentration of the main alleles in the herd PF "Juliana Gore" was 59.3%, rare - 30.4%, respectively. The homozygosity of the analyzed population of Aberdeen-Angus cattle is the lowest in comparison with the data available in the literature and is 0.31. This indicates a very high genetic diversity of this herd, the confirmation which serves the genophond of various breeds - German and Romanian, more detailed research will follow.

The objective of this study was to investigate the effects of water sources on somatic cell count (SCC) and composition of bovine raw milk. The examinations were carried out in a private Holstein farm located in Konya province of Turkey. Before and after changing water supply of the farm (BCW and ACW), all analysis results were recorded. At the BCW period, parameters were noted to be; antimony (Sb): 15.4 µg/L, arsenic (As): 40.98 µg/L, blurriness: 3.3 NTU, mercury (Hg): 2.385 µg/L and iron (Fe): 293.6 µg/L. The values of the same compounds at seven days later ATC time were measured to be <5µg/L, <10 µg/L, 0.74 NTU, 1.457 µg/L and 320.3 µg/L, respectively. According to tank milk test results during seven days before and after the process, the means for dry matter, fat, protein, lactose, density, freezing point, mineral and logarithmic SCC (logSCC) were calculated to be 11.89±0.099 and 12.02±0.111%; 3.01±0.020 and 3.47±0.034% (P<0.001); 3.30±0.044 and 3.17±0.036% (P<0,05); 4.83±0.090 and 4.64±0.063%; 1.0315±0.00099 and 1.0299±0.00071 g/ml; -0.461±0.0042 and -0.466±0.0093oC; 0.673±0.0129 and 0.686±0.0205%; 5.349±0.0453 and 5.228±0.0246, respectively. Changes in water supply caused an increase in fat percentage but, a decline in the protein percentage of tank milk. Individual milk samples of 18 cows at BCW and those collected from 16 cows at ACW shown that mineral increased (P<0.05) but logSCC decreased (P<0.01). Obtained findings here might be attributed to adverse effect of change in Sb, As and Hg on the metabolism.

Donkey milk is considered a substitute for breast milk. Because of its nutritional and compositional properties it is very close to breast milk. Equine asinus can be considered suitable for feeding newborns, against cow's milk, which can cause intolerance. We determined the physico-chemical parameters of donkey milk with CombiFoss FT. The total germ count (TNG) was analyzed by BactoScan and the total number of somatic cells (TNS) by Fossomatic FC. Determination of heavy metals in milk was performed by mass spectrometry to identify Pb, Cd, Cu and Zn. Heavy metals are present in the environment but also in food and can cause serious health problems to the consumer. For the consumer, the main source of cadmium exposure is the food they consume, water and smoking. Cd contamination of dairy milk may also be due to the use of Cd-based chemicals, fertilizers, feed and waste water.

The new systems which assess the nutritive value and determine the nutrient requirement triggered changes in the manner of formulation and development of optimized pig diets. The purpose of this paper is to present a viewpoint on a possible solution for diet optimization. We considered the determination of a possible „common denominator” between the nutritional requirements, mathematical algorithms that can be applied to the stated problem and the economic aspects assimilated as purpose functions in formulating the mathematical models that are used.

The alien fish species Prussian or gibel carp (Carassius gibelio) was introduced to Croatia from Asia several decades ago. The analysis was performed by the official monitoring data from the Final Report for the Ministry of Agriculture of the Republic of Croatia by the Faculty of Agriculture, University of Zagreb during the last eight years (2010-2017) in combination with the statistical analysis of the fisheries data of the Krapina-Zagorje County and Sisak-Moslavina County in the period from 2004 to 2015. The proportion of Prussian carp catches (in kg) increased at Sisak-Moslavina County from 26.45% to 41.84% from 2004 to 2015, leading to a significant decrease of catches of common carp from 25.59% to 8.70%, respectively (r2 = 0,936; p < 0,01). The catch per unit effort (CPUE) of Prussian carp, defined as annual catch by an average angler, significantly increased, from 6 kg at the beginning of this period to 14 kg at its end. These data show that Prussian carp still enlarges its populations along the Sava River.

Improving of goat milk quality is the last trend in goat breeding. Productivity is allready at a high level so we must do the price difference only by the quality parameters. More than that, the market demand high quality products certified as „bio” or „organic”. We analyze, in this case goat milk production, from qualitative point of view, in Murciana Granadina breed, exploited in Romania but imported from Spain. The breeder choice was explained by the fact that this goat breed have maybe the best qualitative paramethers in Spain, so it is possible to obtain high quality dairy products, solving a part of the market demands. Results show us a high conten of fats (5.28%), protein (2.98%) and lact. (4.41%). This paramethers give an important advantage in production of dairy specialties, and of course in increasing of economical value.
