Quality Of Milk

In the article the analysis of bulls-producers used in the republic, depending on polymorphism on k-casein is carried out and the influence of genetic resources on the level of milk productivity, quality of milk and its dampness is determined. It has been revealed that 56 % of bulls in the republic have AA-genotype, 40 % have AB and only 4 % have BB-genotype. The highest yield for 305 days of lactation in cows with BB- and AB-genotypes 6018 and 5985 kg, respectively. Protein content in BB-cow milk was 3.15 %, which is 0.14 % higher in comparison with AA-cows (P ≥ 0.95) and AA-cows – 0.06 % higher. More than a half of all milk examined in the group of cows with BB- and AB-genotype on k-casein (90 and 85 %, respectively) had on rennet and fermentation sample I and II class. In the Udmurt Republic β-asein contains only 26 %, which also affects the quality and yield of finished products, in particular, rennet cheeses.

Promising in feed production is the preparation of haylage with subsequent storage of herbage together with preservatives. The modern market off ers various chemical preservatives in the form of organic acids: propionic, formic, benzoic and their salts. Some disadvantages of preservatives of this group (volatility, toxicity, venom, ability to cause respiratory burns, corrosion, etc.) require to organize a search for new ones based on bacteria and enzymes. The purpose of the work was to increase the level of milk productivity of cows and quality of milk by using the preservatives Biosib and Silostan in the preparation of haylage. Scientifi c and economic experiment has been carried out in LLC “Agrofi rma Bairamgul” in the Uchalinsky area in the Republic of Bashkortostan. For the research, 36 Holstein cows have been selected, from which 3 groups of animals have been formed based on the principle of analogues per 12 heads in each. The input in the ration of lactating cows of grain and legume haylage prepared using the technology with the use of preservatives Biosib and Silostan contributes to the increase in milk productivity. The best eff ect has been demonstrated when using the drug Silostan (the 2nd experimental group), which can be explained by the diverse biological composition of microbes, as well as amino acid complexes, enzymes, vitamins and trace elements. The increase in milk productivity of cows of the 1st and 2nd experimental groups allows to reduce the prime cost of production, respectively according to groups, by 38,7 rubles or 3,31 % and 51,1 rubles or 4,43 %; to increase revenue from the sale of milk by 3186,5 rubles or 4,32 % and 3664,0 rubles or 7,24 %; net profi t by 1791,9 rubles or 17,97 % and 2570,6 rubles or 25,78 % and the level of profi tability by 4,14 and 5,52 % compared to the control group.

Quality Of Milk

Background and Aim: Milk producers need to ensure that their cows are producing high-quality, nutritional milk, which is influenced by the breed, age, nutrition, and health status of lactating animals. The aim of this study was to determine the effect of animal breed, season, and milk production on the physicochemical characteristics of milk and predicting the effect of these changes on the composition and quality of milk products. Materials and Methods: In total, 80 milk samples (40 Simmental and 40 Holstein) were analyzed from LLP "Kirova" of Pavlodar region (Simmental breed) and JSC "Astana-Onim" of Akmola region (Holstein breed) in the Republic of Kazakhstan. The physicochemical parameters, including fatty acid (FA) content, were studied. Results: The Simmental cows had the lowest mass fraction of fat in the spring at 3.94% and the highest fat content in the winter at 4.09%, which was the overall highest fat content measured in both breeds (?<0.001). The lowest protein in the Simmentals was also measured in the spring. The Holstein cows had the highest fat content at 3.8% and the highest protein content at 3.3% in autumn. Conclusion: It was found that the season and breed significantly affected the physicochemical parameters and the FA contents in cow milk. The superiority of the Simmental cows over the Holstein cows throughout the year was statistically significant.

Main Factor

The main factor of determining the level of sanitary and hygienic indicators of the quality of milk produced is the hygiene of milking cows. The study of the role of hygiene of milking is of great importance for a correct understanding of the ways of solving the problem of obtaining high quality milk. Special attention of scientists and practitioners in recent years are focused on the development and implementation of highly effective detergents and disinfectants in the production of milk of cows. Many researchers and practitioners have directed their work to developing measures to prevent the entry of pathogenic microflora into milk during and after milking cows. In spite of many researches carried out, aimed at controlling the number of somatic cells in milk with the use of different products based on lactic acid, chlorhexidine and iodine, the problem of high quality milk production remains unresolved. In our work results of researches on the use of probiotic means for treatment of udders of cows are given. Processing the udder of cows with probiotic means before milking by Skin Cleaner, after milking by PIP Cow Teat Cleaner reduced the amount of somatic cells in cow milk 12,8-84,0%. The use of probiotic means Biomastim lowed somatic cell count of 18,4-51,9%. Microbiological contamination of milk using probiotic means for processing the udder before milking Skin Cleaner, after milking PIP Cow Teat Cleaner decreased 4,9- 70,4 times. The application of probiotic means Biomastim after milking on the teats led to the decrease in milk of cows QMAFAnM 5,0-6,6 times.

One of the main branches of agriculture in the Republic of Sakha (Yakutia) is productive horse breeding. In this regard, we can use the valuable raw materials that the horse gives due to its high adaptability to local conditions. The development of productive horse breeding in particular dairy horse breeding under the conditions of the Republic of Sakha (Yakutia) would allow providing the population with natural, dietary food and more efficient use of land resources. The purpose of the work is to study the effect of zeolite and zeolite-sapropel feed additives in the ration of mares of Megezhek breed on the milk productivity and quality of kumiss under the conditions of Central Yakutia. Two scientific and economic experiments have been carried out where the influence of zeolite from the Suntar deposit (experiment 1) and zeolite-sapropel feed additives (experiment 2) on the milk productivity and physiological parameters of mares of Megezhek breed has been studied. The optimal doses of the effect of zeolite and zeolite-sapropel feed additives on the profi tability of kumiss production have been determined. It has been found in the first scientific and economic experiment that when adding 0,4 g of zeolite per 1 kg of live weight to the daily ration of lactating mares the level of profi tability of milk production increased to 20,4 %, and when adding 0,5 g per 1 kg of live weight the profi tability index increased to 21,5 %, compared to 13,7 % in the control group. In the second scientific and economic experiment the infl uence of the zeolite-sapropel feed additive on the intensity of digestion and assimilation of nutrients in the mares’ rations has been determined. The analysis of the experimental data indicates a high economic efficiency of using zeolite-sapropel feed additive in the 2nd and 3rd experimental groups of mares, where the level of profi tability of production was equal to 27,34 and 32,33 %, respectively, compared to 16,09 % in the control group.

The present study was conducted to investigate the milk quality from different genotype. A total 48 dairy cows belong to different genotypes such as Holstein cross, Jersey cross, Sahiwal cross and Red Chittagong were selected. Milk compositional viz. specific gravity, Acidity test, Fat test, Protein test, Solids-not-fat (SNF) test and total solids (TS) test were carried out. It was observed that the higher specific gravity of milk was obtained from Jersey cross and Red Chittagong genotype, which was significantly higher (P<0.01) than the other genotype of dairy cows. The highest acidity (%) was observed (0.165±0.014) in Red Chittagong and the lowest acidity (0.118±0.025) in Sahiwal cross. The highest fat (%) was observed from Red Chittagong cows milk which was statistically higher from Jersey cross and Sahiwal cross and the lowest fat (%) was found in the milk of Holstein cross cows. The highest SNF value was obtained from Jersey cross and the lowest from Sahiwal cross. On the other hand, Holstein cross and Red Chittagong was nearly similar. Red Chittagong milk sample showed the highest TS value and the lowest value was observed from Holstein cross. The highest protein value was found from Red Chittagong and the lowest from Holstein cross but the protein content of other two genotypes were nearly similar.

The Relationship

The relationship between the quality of milk of different breeds of goat and their diets was assessed. Anglo-Nubian, German White and Alpine goats were used in the experiment, with 7 goats representing each breed. The influence of two diets viz., a routine diet (hay and concentrates) and a diet improved by introduction of granulated alfalfa hay, cabbage and carrots, as well as mixed feed on productivity and characteristics of goat milk were investigated. Goats were machine milked twice daily and the quantity as well as quality of milk were assessed. Results indicated that the milk yield of the Alpine goats increased 3 times; and that of the German White goats increased more than 2.5 times when fed improved diet. Feeding improved diet resulted in significant increase in fat content of milk irrespective of the goat breed. A significant increase in the protein, lactose, and consequentially the, dry non-fat milk solids was observed in Anglo-Nubian and German White goats when fed the improved diet. However, when compared to German White and Alpine goats, highest fat, protein and lactose contents were recorded in milk of Anglo-Nubian goats both on routine and improved diet. The maximum difference in biochemical parameters of milk upon changing the diet was also found in Anglo-Nubian goats. Further, the freezing point and electrical conductivity of the milk decreased irrespective of the breed when goats were fed improved diet. An inverse relationship was found between the protein content in the goats’ milk and the freezing point: with increase in the protein content, the freezing point was reduced.

Basic Approaches

The relevance of research. Currently the methodological base for assessing the breeding qualities of bulls-producers of dairy and milk-meat breeds by the quality of offspring is carried out in accordance with the Instruction approved by the MA of the Republic of Kazakhstan in 2007. The principle of assessment, set out in the Instruction, is to compare the phenotypic indicators of the offspring with each other according to the principle of “peer daughter”. Although this document was approved already in the XXI century, nevertheless the basic approaches, which were put the basis, were developed in the first half of the last century and currently do not correspond to modern scientific principles. At the same time the world leaders in the field of breeding in dairy cattle breeding have been successfully using the BLUP method in breeding practice to assess the breeding qualities of animals for decades. This principle of assessing the breeding value of bulls is the most theoretically grounded and allows you to obtain results comparable to each other. Therefore the development and optimization of the equations of mixed BLUP models is extremely relevant for the conditions of the Republic of Kazakhstan from both scientific and practical points of view.Material and research methods. The material of the research was the data on the phenotypic indicators of the signs of milk productivity of first-calf cows of the Holstein black-and-white breed obtained from the republican database of the Republic of Kazakhstan for 2016-2017. As a criterion for choosing the best equation the residual variance values of each model under study were used.Results: when improving the method for assessing bulls-sires of the Holstein black-and-white breed according to the quality of offspring, out of the four studied equations of the mixed BLUP model one equation was optimized to assess the breeding qualities of the sires. In principle, to assess the breeding qualities of producers by the quality of offspring it is possible to use any of the models under consideration, since the established differences for all analyzed characteristics of milk productivity are insignificant (no more than 6%)

Milk And Dairy Products

Because of the increasing trend in globalization in dairy farming resulting in joining and taking over some companies with the aim of rationalization of production and realizing greater market participation, it seems quite real to expect such a trend to appear in our country as well. After the process of privatization had been realized a significant part of Montenegrin economy fell into the hands of private owners. In such conditions it can be expected that efficiency and competitiveness of some producers of milk and dairy products in the Republic of Montenegro will be increased, since in previous period this industry was characterized by insufficient exploitation of already existing capacities for milk processing while the quality of milk was considerably under the standards prescribed by the European Union. Depending on the dynamics of entering Montenegro into international economy the national dairy industry must be ready to face the challenge which will certainly be imposed on it. The object of this paper was to try to find the answers to the two questions. First where we are now and where we will be in the next five years in order to improve the competitive potential of domestic dairy farming.

В работе приводится схема гидролиза сырого протеина в рубце с образованием метаболита, а также методика расчета усвоенного протеина, микробного протеина и баланса азота на примере сена злаково-разнотравного. Представленные формулы легли в основу программы АСТРА , которая позволяет составлять необходимые рационы для крупного рогатого скота с учетом показателей белковой обеспеченности. Рацион в программе рассчитывается по 36 показателям питательности, а его анализ производится по 20 показателям. Демонстрация работы программы осуществлялась на примере анализа хозяйственного рациона в сельхозпредприятии Республики Башкортостан. Расчет показал, что набор кормовых компонентов для коров с молочной продуктивностью 24 кг в сутки и массой 500 кг подобран оптимально, что позволяет данному хозяйству получать высокие удои от коров. В рационе преобладают сочные корма (39,29), которые положительно сказываются на молочной продуктивности, так как некоторые компоненты относятся к молокогонным кормам. Программа выявила и слабые места рациона. Установлено, что в нем наблюдается незначительный избыток обменной энергии 2,0, сырого протеина 5,0 и переваримого 1,0, при этом не хватает 41,0 нерасщепляемого протеина. Рацион нуждается в дополнительном обогащении незаменимыми аминокислотами, такими как лизин, в количестве не менее 25,0 г и триптофан не менее 35,0 г. Алгоритм работы программы позволяет проводить зооанализ составленного рациона с учетом изменяемой питательности. Помимо расчетов можно выявить недостатки и дать соответствующие рекомендации по их устранению.The work presents the scheme of raw protein hydrolysis in the rumen with the formation of a metabolite, as well as the method used to calculate digested protein, microbial protein and nitrogen balanced on the example of hay containing grain and various herbs. Presented formulae were used as the foundation of ASTRA program allowing to create the required diet plans for large cattle taking the values of protein sufficiency into account. The program calculates the diet plan according to 36 nutritiousness parameters, its analysis is carried out using 20 parameters. The demonstration of programs work was carried out on the example of the analysis of farm diet plan in an agricultural enterprise located in the Republic of Bashkortostan. The calculation showed that the set of feeding components for cows with milk productivity amounting to 24 kg per day and body weight of 500 kg was selected correctly, which allows the farm to achieve high cow milk yield. The predominant part of the diet is succulent feed (39.29) which positively influences milk productivity due to the fact that certain components stimulate milk production. The program was also able to detect the downsides of the diet plan. It was found that there is a slight excess of metabolic energy (2.0), raw protein (5.0) and digestible elements (1.0), as well as 41.0 insufficiency of by-pass protein. The diet plan required additional enrichment with such essential amino acids as lysin in the amount of not less than 25.0 g, and tryptophan not less than 35.0 g. The algorithm of work of the program allows carrying out the animal analysis of the diet plan created taking changeable nutritiousness into account. Apart from calculation, it is possible to identify existing downsides and give the corresponding recommendations that can be used to eliminate them.
