The aim was of this study was to discover the adaptation indicators of different breeds first-calving cows to voluntary (robotic) milking system during the first month of lactation. The research was carried out in a robotic farm on German Holstein, French Holstein breeds and Brown Swiss breed of cows. During the adaptation period, the German Holsteins were differed from the rench Holsteins and Brown Swiss breed by milk yield, multiplicity of milking, and the amount of consumed concentrated feed. On the 30th day (end of adaptation period), the German Holstein breed dominated over the French Holstein breed and Brown Swiss having average daily milk yield by 0.73 and 4.12 kg, milking times by 0.26 and 0.34, the amount of consumed concentrated feed by 0.32 and 0.61 kg higher. In addition, the German Holstein breed during the adaptation period was distinguished by higher multiplicity of passages through the selection gate and the number of visits to feed stations. Important indicators of adaptation to free keeping and voluntary milking are the number of cases of forced milking. On the 5th day of lactation, some 69.4–86.2% of cows of all the groups did not enter the milking robot. This indicator has been steadily declining every five days. On the 30th day of lactation the cases of operator-forced milking were 24.3–35.9% and they were the lowest in cows of the German Holstein breed, indicating the best adaptive qualities of this cattle. The German Holstein breed had more lower (by 0.30 and 0.26 mS/cm) electrical milk conductivity on the 30th day compared with French and Brown Swiss breeds. In addition, the number of somatic cells in its milk was lower by 19.4 and 17.1 thousand cells per cm3 compared with French Holstein and Brown Swiss breed. Therefore, we suggested that the German Holstein breed has more higher stress tolerance, and hence a shorter adaptation time to the keeping.

The aim of this work was to study bioenergetic and ethological indicators in crossbred first-calf heifers compared to purebred first-calf heifers. The research was conducted on the first-calf heifers of Ukrainian Black-Pied dairy breed and first-generation crossbreeds obtained as a result of crossing with Brown Swiss breed, as well as, on the first-calf heifers of Ukrainian Red-Pied dairy breed and first-generation crossbreeds obtained as a result of crossing Ukrainian Red-Pied dairy with Montbéliarde breed. The purebred Black-and Red-Pied first-calf heifers prevailed over crossbreed first-calf heifers on the indicator of milk yield for 305 days of lactation by 106.45 and 218.36 kg, respectively. Accordingly, the indicators of average daily milk yield were also higher by 0.35 and 0.72 kg and the indicators of average daily milk yield adjusted by 4 % fat content per 0.15 and 0.16 kg. At the same time, the indicator of average fat content in milk prevailed in crossbreeds of Black-Pied and Brown Swiss breed by 0.08 % compared to purebred Black-Pied breeds, and in Red-Pied crossbreeds with Montbéliarde breed by 0.16 % compared to purebred Red-Pied breeds. The purebred Black-Pied first-calf heifers had an advantage by 2.04 MJ compared to crossbreeds, while the Red-Pied first-calf heifers had a slight advantage by 0.06 MJ compared to crossbreed first-calf heifers on the indicator of daily cost of exchange energy (EE). The purebred Black-and Red-Pied first-calf heifers had higher cost of exchange energy allocated with milk compared to crossbreed first-calf heifers by 0.42 and 0.82 MJ. They also had higher cost of exchange energy rates for heat products by 0.79 and 0.25 MJ. According to the energy index indicator, purebred Black - and Red-Pied first-calf heifers prevailed over crossbreeds first-calf heifers by 0.16 and 0.07 %, respectively. The same trend was observed in relation to the productive index indicator. The purebred Black-and Red-Pied first-calf heifers had a slight advantage by 0.001 and 0.002 kg adjusted by 4 % of milk fat content per 1 MJ. According to the indicators of daily behavioral reactions, no special differences between a purebred and crossbreed were found.

The results of the study of milk productivity and lactation rates of fi rst-calf cows are presented. The research into fi rst-calf cows of black-andwhite Holstein breed, belonging to sire lines of Wis Ideal 1013415 and Refl ection Sovereign 198998 was conducted in 2018 in Novosibirsk region. The number of cows under study was 64, the period of the study covered 305 days of lactation. Monitoring of milk production, milk fl ow intensity, fat and protein content was carried out monthly. The research materials were analyzed for groups of cows depending on their sire line and productivity for single and daily milk yield, fat and protein content, and dynamics of milk ejection for the fi rst 3 minutes of milking. The highest daily milk yield in both lines was observed in the second month of lactation. In the fourth and fi fth months of lactation, the average daily milk yield of Refl ection Sovereign cows was signifi cantly higher (р < 0.001) than that of their peers of the Vis Ideal line, by 1.3 kg. During the lactation period, the productivity of the Vis Ideal and Refl ection Sovereign cows was almost the same: milk yield – 8296 and 8220 kg, fat content – 4.02 and 4.06%, protein – 3.36 and 3.35% and milk fl ow intensity – 2.70 and 2.78 kg/min, respectively. In the second and third months of lactation, cows of both lines had a decrease in the content of fat, protein and intensity of milk fl ow with a gradual increase in these indices in the fourth and fi fth months of lactation. First-calf cows of the black-and-white breed of Canadian selection of different sire lines showed a high level of milk productivity and proved to be suitable for further breeding work.

Abstract. The aim of this study was to determine whether feed intake amount and feed intake behaviour could be related to oestrus in dairy cows. Furthermore, we investigated whether oestrus had an effect on daily milk yield. A total of 138 oestrus cycles, leading to conception of 100 cows, were analysed. The parameters "daily fresh matter intake amount (kg)", "daily number of visits to the feeding trough" and "time spent feeding per day (min)" were electronically measured and recorded. For a sub-quantity of all animals, daily milk yield (kg) was recorded continuously and stored in the herd management software. Special attention was given to the day of oestrus, which was defined as the day of successful insemination. All remaining days of the oestrus cycle were considered as the reference period. Among all animals and cycles, fresh matter intake amount per day, number of visits per day, and time spent feeding per day were reduced by 10.3, 9.1 and 20.8 %, respectively, on the day of oestrus. Fresh matter intake was significantly lower in primiparous cows than in multiparous cows. However, number of visits to the trough and time spent feeding per day were significantly higher in primiparous cows compared to multiparous cows. Day of oestrus did not have a significant effect on daily milk yield, as this parameter was characterized by high variation among all days of the oestrus cycle. In conclusion, if an RIC system is used, monitoring of feeding behaviour appears to be a potential auxiliary aid in oestrus detection.

The technological properties of the udder of cows have been studied under the conditions of using a robotic milking system. The research material was Holstein cows in the peasant (farm) economy of the Republic of Tatarstan, serviced by "Astronaut A4" robotic milking from "Lely Industries N.V.". A method for selecting cows for robotic milking has been developed. At the same time, in the herd, first, cows of the 1st lactation at 2-4 months of lactation are assessed according to the duration of milking and animals with duration of milking from 3 to 6 minutes are selected. Then, cows are selected from this group, whose lactation intensity indicator at 2-4 months of lactation exceeds the average value of this group by 0.5 sigma (M + 0.5σ), where M – the arithmetic mean of the indicator; σ – the standard deviation of the indicator. The proposed selection method makes it possible to form a breeding core and increase the milk yield in 305 days of lactation in the group of first-calf cows by 9.5 % (P˂0.01), daily milk yield – 14.4 % (P˂0.001), the milk flow rate – 33 % (P ˂ 0.001) and reduce the duration of cows' stay in the boxing by 17.5 %, the duration of milking cows – 21.7 %. When using this method, the efficiency of using robotic technology for milk production is increased.

The automatic milking systems (AMS) have been deeply studied in dairy cows applications, but not in the case of buffaloes; although, a few applications to the species can be found in literature. The objective of this study is to compare some important functional aspects of AMS with the conventional milking systems. Aspects such as adaptation of buffalo to AMS and the possible relationship between milking frequency and daily milk yield were evaluated. Two groups of <em>Bubalus</em> <em>bubalis</em> were reared in the same barn, in a farm located in Piana del Sele (SA) southern Italy. Fourty <em>primiparous</em> <em>buffaloes</em> were milked using an AMS, and at the same time another herd of 40 were milked twice a day using traditional milking system (tandem). The adaptation period of buffaloes to AMS was 2 months. Milking frequency with the AMS was significantly higher compared to the one of traditional methods (2.3±0.17 times/d <em>vs</em> 2 times/d). Daily milk yield with the AMS was observed to be significantly higher than with traditional milking system (7.9±1.3 kg/d <em>vs</em> 6.9±1.06 kg/d). In this study, there was no significant relationship between the increase of daily milking frequency and daily milk yield. We can conclude that a positive AMS effect on daily milk yield and milking frequency is possible and so we can expect successful applications of the AMS to dairy buffalo farms.

Исследована зависимость молочной продуктивности и воспроизводительных качеств коров ярославской породы и ярославско-голштинских помесей в стаде от наличия у них дополнительных сосков. Объекты исследований коровы ярославской породы и помеси с голштинской породой разной кровности, содержащиеся в стаде одного из сельскохозяйственных предприятий Ярославской области. Было исследовано 307 коров, при глазомерной оценке стада выявлено 60 голов с полителией и 247 не имеющих дополнительных сосков.При подборе коров для машинного доения важное значение придаётся форме, размерам и расположениям сосков. Определённая стандартизация по этим признакам позволяет повысить эффективность доения аппаратами. Из исследуемого поголовья полителия наблюдается у 29 голов ярославской породы и 31 ярославско-голштинской помеси. 32 полителийные коровы (53,3) имели по одному добавочному соску и 28 коров (46,7) по два.Наибольшая встречаемость полителии наблюдается у коров с округлым выменем (47 гол., или 78,3), наименьшая у коров с ваннообразной формой вымени (6 гол., или 10). Для исследования функциональных, качественных свойств молочной железы к выборке животных срудиментарными соскамибыли подобраны сверстницы по возрасту, возрасту 1-го отёла и количеству законченных лактаций. Установлено, что надой за 305 дней 1-й лактации больше у коров без полителии на 308 кг, суточный удой выше на 2,8 кг, скорость молокоотдачи на 0,12 кг/мин. Коровы-сверстницы без дополнительных сосков превышают практически все показатели молочной продуктивности полителийных коров. Таким образом, селекция по морфофункциональным свойствам вымени будет способствовать повышению продуктивности коров стада и эффективному использованию доильного оборудования, снижению себестоимости продукции.The dependence of milk productivity and reproductive qualities of cows of the Yaroslavl breed and Yaroslavl-Holstein crossbreeds in the herd on the presence of additional dugs was studied. Objects of research are cows of the Yaroslavl breed and crossbreeds with Holstein breed of different blood levels containing in the herd of one of the agricultural businesses of the Yaroslavl region. 307 cows were examined, 60 animals with polythelia and 247 animals without additional dugs were found with a visual appraisal of the herd. When selecting cows for machine milking, great importance is attached to the shape, size and location of the dugs. A certain standardization on these features can increase the efficiency of milking by machines. From the studied livestock polythelia is observed in 29 heads of the Yaroslavl breed and 31 in the Yaroslavl-Holstein crossbreed. 32 polythelial cows (53.3) each had one additional dug and 28 cows (46.7) each had two dugs. The highest occurrence of polythelia is observed in cows with a round udder (47 heads or 78.3), the smallest - in cows with a bath-shaped udder (6 heads or 10). To study the functional, qualitative properties of the mammary gland herdmates were selected according to the age, age of the first calving and the number of completed lactations for a sample of animals with rudimentary dugs. It was found that milk yield for 305 days of first lactation is 308 kg more for cows without polythelia, daily milk yield is 2.8 kg higher, milk flow rate is 0.12 kg/min. Cows-herdmates without additional dugs exceed almost all indicators of milk production of polythelial cows. Thus, selection by the morphofunctional properties of the udder will increase the cow productivity of herd and the effective use of milking equipment, reduce the cost of production.

Abstract This study was carried out to determine the genotype and allele frequencies and association between the Leptin gene Sau3AI polymorphism and some performance characteristics in Simmental (n=60) and Brown Swiss (n=62) breed cattle raised in the province of Erzurum, Turkey. In the study, leptin/Sau3AI gene polymorphisms in DNA isolated from blood samples obtained from Simmental and Brown Swiss cattle were determined using PCR-RFLP method. As genotype frequencies of leptin/Sau3AI gene in the population, in Brown Swiss cattle, 88,7% with genotype AA, 9,7% with AB and 1,6% with BB genotypes were determined, Simmental breed cattle, 78,3% with genotype AA, 16,7% with AB and with 5,0% BB genotypes were determined. AA genotype frequencies were the highest in the population, and those with BB genotypes had the lowest frequency in both breeds. When the population was examined in terms of allele frequencies, the A allele was 0,87 and B allele was 0,13 in the Simmental cattle, and the A allele was 0,94 and B allele was 0,06 in the Brown Swiss breed. According to Hardy-Weinberg genetic balance test, the distribution of genotype frequencies was balanced (P>0.05) in the Brown Swiss breed but not in the Simmental breed in the population studied. As a result of the analysis performed in the Simmental breed, the general averages were found to be 5422,4 ± 1901,74 kg for actual milk yield, 5626,6 ± 1475,85 kg for 305-day milk yield, 298,7 ± 84,80 days for lactation duration and 18,5 ± 4,84 kg for daily milk yield. According to the statistical analysis results, the effect of genotype on the actual milk yield during lactation, lactation duration and daily milk yield was significant. As a result of the analysis made in the Brown Swiss breed, the general averages were 3917,8 ± 1584,38 kg for actual milk yield, 4614,3 ± 982,62 kg for 305 days milk yield, 254.9 ± 99.88 days for lactation duration and 16,0 ± 3,82 kg for daily milk yield. According to the statistical analysis results, the effect of genotype on performance characteristics was insignificant in Simmental and Brown Swiss cattle.

A database consisting of 35291 milking records from 83 cows was built over a period of 10 months with the objectives of studying the effect of teat cup attachment failures and milking interval regularity on milk production with an automated milking system (AMS). The database collected records of lactation number, days in milk (DIM), milk production, interval between milkings (for both the entire udder and individual quarters in case of a teat cup attachment failure) and average and peak milk flows for each milking. The weekly coefficient of variation (CV) of milking intervals was used as a measure of milking regularity. DIM, milking intervals, and CV of milking intervals were divided into four categories coinciding with the four quartiles of their respective distributions. The data were analysed by analysis of variance with cow as a random effect and lactation number, DIM, the occurrence of a milking failure, and the intervals between milkings or the weekly CV of milking intervals as fixed effects. The incidence of attachment failures was 7·6% of total milkings. Milk production by quarters affected by a milking failure following the failure was numerically greater owing to the longer interval between milkings. When accounting for the effect of milking intervals, milk production by affected quarters following a milking failure was 26% lower than with regular milkings. However, the decrease in milk production by quarters affected by milking failures was more severe as DIM increased. Average and peak milk flows by quarters affected by a milking failure were lower than when milkings occurred normally. However, milk production recovered its former level within seven milkings following a milking failure. Uneven frequency (weekly CV of milking intervals >27%) decreased daily milk yield, and affected multiparous more negatively than primiparous cows.

Studies conducted in farm conditions, the company, OOO PZ «Nasha Rodina» in Sokolovsky village of Gulkevichsky district of Krasnodar region. The aim of the research was to study the use of the PassPro Soy feed product consisting of protected soy protein in the diets of new-bodied highly productive cows. 2 groups of cows of the red-mottled Holstein breed were formed, selected according to the principle of pairs-analogues: by age in calving, calving time, live weight, productivity for the past lactation, fat and protein content in milk. The ration of the first control group was the ration accepted on the farm for newbodied cows. The diet of the second experimental group was the same as in the first control group, only 1.5 kg of compound feed was replaced with 1.5 kg of PassPro Soy, which is a protected soy protein in the form of a 5 mm granule. During the milking period, the daily milk yield of cows in the control group was 30.80±1.07 kg. The daily milk yield of cows of the second group, where 1.5 kg of compound feed was replaced by 1.5 kg of PassPro Soy, significantly increased by 6.6 %. Due to the increase in the gross milk yield, there is a tendency to increase the amount of milk fat in the milk of cows of the second group by 6.9 %, as well as milk protein by 11.3 %. In the experimental group, when replacing 1.5 kg of feed taken on the farm with 1.5 kg of PassPro Soy, milk productivity increased by 2.03 kg. Additional profit from the sale of milk in the experimental group increased by 48.72 rubles. for 1 head per day. The economic efficiency in the second experimental group was 6.30 %.

A study of the influence of sires of Holstein breed on their daughters’ milk productivity, development and milk physical and chemical characteristics was conducted. The study was carried out in Krasnoyarsk Territory on red-and-white cows of the first and second lactations – daughters of three sire bulls: Arsenal, Zaryad and Veles. It was established that sires affect their daughters’ daily milk yield, lactose content in milk and milk solids non-fat (MSNF). The difference in traits between individual groups of bulls’ daughters is statistically significant. Analysis of variance showed that the paratypic factor defined as the age of daughters in lactations had a significant effect on daily milk yield. The genetic factor, that is father's heredity, influenced only the content of urea in daughters’ milk. Analysis of the correlation between daily milk yield and physical and chemical properties of milk revealed reliable correlated response of weak strength: in the daughters of the Arsenal bull (the second current lactation) it was between the traits of daily milk yield and protein, in the daughters of the Veles bull (the same lactation) it was between the traits of daily milk yield and MSNF, and daily milk yield and the freezing temperature of milk (FTM). In cows of the first lactation, a strong correlation was found between some physical and chemical properties of milk, such as fat and urea, urea and FTM, and MSNF and FTM. In cows of the second lactation, a strong correlation was found between the following traits of milk: protein and MSNF, protein and dry matter, lactose and MSNF, MSNF and urea, and some others. It is shown that sires of Holstein breed have an impact on certain productivity parameters of their cowdaughters. It is recommended to use the bull Arsenal 8492 more widely to increase the milk yield of their daughters, and Veles 5417 – to improve the quality of milk of their daughters.
