The aim of this study is to achieve a comparative analysis of the cow livestock number, production of milk and of main dairy products in Romania and European Union. The work is an extensive bibliographic documentation with the application of statistical tests for the period 2017-2021. At European Union level the herd of dairy cows is in decreasing with 5.63% and in Romania with 7.95%, from 1175.4 thousand heads in 2017 to 1081.9 thousand heads in 2021. The largest amount of raw milk available on the farm in 2021 belongs to Germany which records 32531.56 thousand tons, approx. 21% of the total quantity at EU level. In 2021 compared with 2017, the Europeans consumed with 3.91% less fresh dairy products and with approx. 5% more cheese. In the future, will be exploit more productive animals, making cow rearing a part of solutions in food crisis. [ABSTRACT FROM AUTHOR]

The global beef industry has been growing steadily in recent years due to the fact that the largest beef exporters and importers in beef producing countries continue to invest financially in the global market. Beef, one of the most important products in the world livestock market, is often recognized as a premium source of protein in the human diet, therefore it is widely consumed in most countries around the world. In 2020, at the national level, the number of cattle slaughtered in industrial units (slaughterhouses) decreased by 15.6% compared to the previous year. Also, the beef production decreased from 196,000 tons in 2017 to 173,000 tons in 2020, even though the slaughter yield has increased. There are about 1 billion beef cattle worldwide, and compared to poultry and pigs, beef cattle have the lowest feed-to-meat conversion efficiency. Strategies to improve beef cattle performance emphasize operational and reproductive management, host genetics, functional efficiency of the rumen and respiratory microbiome, and forage structure and composition. There have also to consider the herd health and immunity and the need for beef cattle to thrive in a changing environment. [ABSTRACT FROM AUTHOR]

The paper aims to highlight the productive performance of the Pinzgau breed exploited in the Dornelor Basin, Suceava County. In this sense, a herd of 12 head of cattle, belonging to the Pinzgau breed, was studied, both the red variety and the black variety, which were followed by the productive performances at the ascendancy and descent of the nucleus from the farm. Also, the parameters regarding the quality of milk obtained from the studied cattle were analyzed. The ancestry of the studied herd is valuable with productions in the mother (M) of 5496 kg of milk, 4.22% fat and 3.39% protein, in the mother of the father (MT) of 5562 kg of milk, with 4.095% fat and 3.45% protein, and in the mother's mother (MM) of 5613 kg milk with 4.21% fat and 3.49% protein. The milk production in the offspring had an increasing evolution as follows: on total lactation 5922 Kg milk in lactation I and 6474 Kg milk in lactation II, and on normal lactation of 4820 Kg milk in lactation I and 4843 Kg milk in lactation II with average values of 4.26% fat and 3.24% protein in lactation I respectively 3.91% fat and 3.29% protein in lactation II. Regarding the quality of the milk, it had an average value of 86,000 thousand / ml milk in the total number of somatic cells (NCS) which shows us a quality milking, in hygienic conditions, respectively keeping the milk after milking in hygienic conditions, which shows the farmer's care for the cattle on the farm.

In this scientific paper, the productive performances of beef cattle belonging to the Aberdeen Angus and Charolaise breeds from 6 farms in Neamț County were analyzed, studying the following indicators: birth weight (kg), body weight (kg), and average daily gain (g) at the age of 200 days (kg), and also 365 days (kg). The data on average values and variability of meat production indices show that the highest performances were 42.33 kg at birth, 246.29 kg and the average daily increase of 1030.71 grams per 200 days, and 433.69 kg with the average daily increase of 1074.33 kg, at the age of 365 days. On the last place was farm 1, which registered an average weight at birth of 30.70 kg, at 200 days this indicator was 188.59 kg, and the average daily gain was 786.20 grams; at 365 days the average weight was 320.84 kg and the average weight was 793.11 kg. Farm 1 raises the Aberdeen Angus breed, and farm 5 raises the Charolaise breed, which has better results due to the constant care of the breeder to improve the genetic material.

In this study, the productive performances of the ascendants and descendants of the cows' herd belonging to the 4 basic breeds were analyzed, as follows: Holstein, Băl?ată cu negru românească (Romanian Black Spotted), Băl?ată românească (Romanian Spotted), and Brună de Maramure? (Maramures Bown), from 7 farms of Neam? county, which were encoded with numbers from 1 to 7. For the analysis of the ascendants' performances - mother (M), paternal grandmother (MT), and maternal grandmother (MM) - and of the offspring' performance, 3 indicators were determined regarding the milk production: the quantity per normal lactation (kg), the percent of fat, and the percent of protein. It was found that the best milk production in normal lactation of offspring was recorded in farm 2 (6161.25 kg), where a mixed herd of Holstein and Băl?ată cu negru românească breeds is raised. If we compare the phenotypic performances of the ascendants (mother of mother - MM), which realized an average milk production of 7205.44 kg, with the father's mother (MT) of 11.931 kg, and the mother's mother (MM) of 7949.83 kg we confirm that the phenotypic performance for the milk production in the offspring does not reach the level of those obtained by ancestry. This fact is due to management deficiency regarding the external factors. [ABSTRACT FROM AUTHOR]

It is weel known that in order to increase progress on cattle farms it is necessary to monitor animals in order to determinate the genetic quality of animals, by assessing the quantitative and qualitative characters of the animals, estimating breeding values and setting up a database on these aspects. In our country, as a result of favorable factors, such as natural pasture potential, European subsidies, government programs for the purchasing animals, extensiveintensive growth technology systems, the price of bovine meat, population trends towards the consumption of meat obtained in ecological conditions, in Romania were imported a series of specialized breeds for meat production, including Aberdeen Angus, Galloway, Highland, Aubrac, Charolais, Limousin. Thus, in order to expand the database and monitoring the qualitative and quantitative characters of the animals, specific breeding programs to each breed were developed. Regarding the Aberdeen Angus breed, the genealogical register is held by the Aberdeen Angus Association from Sibiu county, which also leads the activity of official performances control on national level. Recordings are made in accordance with legislative framework, in herds of pure breed Aberdeen Angus cattle and also cross-breeding programs with Aberdeen Angus terminal bulls. The control purpose is to record the weights of calves between three and fourteen months old, observing the specific characters of Aberdeen Angus breed and managing all purebred bulls. Data is collected in order to provide farmers with information useful for herd management and raw data for genetic evaluations. Generally, in this paperwork it will be studied the legislative framework, the control technique, the control methods, the national evolution of performances, the stock evolution and the appreciation of the bulls.
