The aim of this work was to compare somatic cell count in milk used for making steamed cheese Parenica in Slovak industrial dairies and small farm dairies and to find out whether somatic cell counts in milk affect the dry matter content of Parenica cheese. The samples of raw milk were taken from 3 industrial dairies (A, B, C) and from 3 farm dairies (E, F, G), produced traditional Slovak cheese Parenica in period from January untill December 2018. The somatic cell count in milk was determined by FossomaticTM 5000 (Foss, Denmark) and dry matter of cheese by oven drying method to constant weight. There were no statistically significant differences (p >0.05) for somatic cell counts in milk processed in industrial and farm dairies. Lower somatic cell counts were determined in milk amples from industrial dairies (mean value 326.55 thousand in 1 mL) in comparison to milk samples from farm dairies (mean value 507.67 thousand in 1 mL). Statistically lower dry matter content (p <0.01) in the samples of Parenica cheese was found out in farm dairy E in comparison to other dairies. The relationship between somatic cell count in milk and dry matter in cheese was confirmed by the relatively low correlation coefficients in dairies, A = 0.22; C = 0.15 and F = -0.12 and higher correlation coefficients in dairies, B = -0.32; D = 0.45 and E = -0.48. Obtaining a more accurate effect of somatic cell count on cheese quality requires the continuation of the research on a larger number of samples and consideration of other factors.

Analysis of lactation curves of milk, basic milk constituents, somatic cell count and urea in milk provide sufficient information for efficient dairy herd management and also is significant in genetic evaluation. The aim of the study was to apply the Wood’s model to fit lactation curve of milk yield as well as fat, protein, dry matter, lactose, somatic cell count and urea in cows’ milk. This study was conducted on dairy cows of Montbéliard (n = 686) and Polish Holstein-Friesian (n = 933) breeds. We analyzed data on the above mentioned milk constituents in the samples collected between 1995 and 2007. Data from 5,034 lactations were collected. Type C1 of the curve typical for standard lactation was the most frequent when daily milk yield, lactose and urea were analyzed. However, curves of fat protein and dry matter were described as type C4. The Wood’s model showed the highest accuracy when milk yield and protein content were investigated; poor fitting was observed for fat content. The Wood’s model brought better accuracy for Polish Holstein-Friesian cows compared to Montbéliards. Precision of mathematical models fitting is R2 (adjusted determination coefficient). The highest values of R2 were noticed when lactation and protein curves were investigated. The lowest R2 was determined for urea and somatic cell count.

The average somatic cell count in the milk analysed was 326,000 cells/ml. For the 4 groups of cows distinguished in the study, with daily milk yield of ≤15 kg, 15-25 kg, 25-35 kg and >35 kg, the somatic cell count was 771,000, 393,000, 240,000 and 180,000 cells/ml, respectively. Statistical analysis revealed significant differences in the somatic cell count in milk from cows with different productivity. A highly significant correlation coefficient was obtained for the daily milk yield of the cows and the somatic cell count in the milk (r=−0.81). The negative coefficient indicates that an increase in the quantity of milk was accompanied by a decrease in the somatic cell count in the milk. The regression equation obtained suggests that in the study population a decline in somatic cell count of 100,000 cells/ml was accompanied by an increase in daily milk yield of 3.8 kg. The analysis showed that there is a negative correlation between SCC and milk yield of cows. An increase in milk yield was found to be accompanied by a decrease in the number of somatic cells in 1 ml of milk, which indicates an improvement in its quality.

Abstract. The aim of present study was to investigate the relationships between temperament score and milk production, as well as somatic cell count in a herd of Jersey and Holstein Friesian breeds. The temperament of 283 Jersey and 69 Holstein Friesian cows were assessed (scored) by the temperament score test (behaviour of animals was assessed in a 5-score system (1: calm, 5: nervous) while spending 30 s on the scale during weighing). The daily milk yield, fat, protein content and somatic cell count were also investigated in this study. Our investigation did not reveal any correlation between daily milk yield and temperament score. But milk somatic cell count was showed positive moderate relation with the temperament scores of Jersey (rrank=0.67; P=0.0001) and Holstein Friesian (rrank=0.66; P=0.0001) cows. Calmer cows had lower somatic cell count (Jersey: 135.40×103/cm3; Holstein Friesian: 176.07×103/cm3) compared to the more temperamental cows (Jersey: 540.44×103/cm3; P=0.0001; Holstein Friesian: 744.91×103/cm3; P=0.0001, resp.).

Abstract. The aim of this study was to determine the influencing factors on somatic cell count (SCC) in the milk of Holstein Friesian (HF) and Brown Swiss (BS) cows raised on three dairy farms under the Mediterranean climatic conditions in Turkey. For a two-year period, farms were visited monthly to measure daily milk yield (DMY) and collect milk samples from each cow during the morning and evening milking. Total of 1 429 SCC readings from 67 HF and 16 BS cows were analyzed by using repeated measures. Breed (P<0.01), lactation number (LN) (P<0.01), milking time (MT) (P<0.05), lactation month (LM) (P<0.01) and the interactions of breed-LM (P<0.05), herd-LM (P<0.01) and LN-LM (P<0.01) effects on SCC were statistically significant as did the co-variable DMY effect (P<0.01). The effect of herd and herd-MT interactions on SCC were statistically insignificant (P>0.05). The SCC means for BS and HF cows were 5.464±0.060 (291 072 cells/ml) and 5.654±0.029 (450 817 cells/ml), respectively. The SCC mean for morning milking (338 065 cells/ml) was 25 850 cells/ml lower than that of evening milking. The LN4 had the highest SCC mean (490 908 cells/ml) and was statistically different from those of LN1 (P<0.01) and LN2 (P<0.05). The SCC level was the highest in the first LM (601 174 cells/ml) and this level then decreased in the later months. Possible reasons for the difference in SCC means between the breeds are different resistance mechanisms against mastitis, different morphological conformations of udders and different milk yields between these two breeds. The insignificant differences found among herds show the similarities of management, milking hygiene and barn conditions. In order to decrease SCC in milk and increase udder health, some precautions need to be taken like improving milking management, hygiene and barn conditions, milking the cow at uniform intervals, feeding the cows after the milking and applying a mastitis control program.

Abstract. Dairy cows of 2 breeds, 74 Holstein (H) and 72 Czech Fleckvieh (C) cows in the 1st (H, n=38; C, n=38) and 2nd lactation (H, n=36; C, n=34) during the 1st period (n=74; H, n=40; C, n=34; to 150 days) and the 2nd period of lactation (n=72; H, n=34; C, n=38; above 150 days) were observed. Differences in external and internal proportions of teat closely before (the 1st measurement), immediately after (the 2nd measurement) and 3 h after milking (the 3rd measurement), udder conformation evaluated by linear description, somatic cell count, daily milk yield and the time of milking were evaluated in relation to the effect of breed and period of lactation. The length of the teat canal, area of the teat end, and wall thickness were measured from the axial picture recorded by ultrasound Aloka SSD500 (Aloka Co., Ltd., Tokyo, Japan). Significant interbreed differences were detected in external as well as internal teat proportions (P<0.05–0.001). Relative changes of teat diameter, comparing C and H cows, differed significantly between the 1st and the 3rd measurement (P<0.05). The length of teat increased during milking and didn´t achieve the beginning size during 3 h after milking. Significant diiference in the length of teat between the 2nd measurement and the 3rd measurement was determined in H cows only (P<0.001). The most significant changes of the length of the teat canal and the area of teat were found in both breeds between values measured closely before and immediately after milking (P<0.5–0.001). Wall thickness was strengthen in C cows (+15.6 %) during the 2nd measurement according to the 1st (P<0.05), while difference represented +18 % (P<0.001) in H cows. Non-significantly higher values of external proportions of teat were measured in the 2nd period of lactation except diameter of teat closely before milking. Internal proportions of teat were always significantly higher in the 2nd period of lactation in relation to the 1st period. Prolongation of teat canal by 0.15 cm (P<0.01) closely before, by 0.16 cm (P<0.001) immediately after, and by 0.13 cm (P<0.01) 3 h after milking was measured in the 2nd period of lactation. The area of teat end measured before milking was significantly larger in the 2nd period of lactation (P<0.01).

With the aim of determining the effect of response to heat stress, parity, breed and breeding region on somatic cell count (SCC) in dairy cattle, the individual test-day records of dairy cows collected from 2005 to 2012 in regular milk recording (AT4 / BT4 method) in Croatia were used. The proportional differences in log somatic cell count, and logSCC (in %) in subsequent milk recordings (1st, and 2nd) were determined in cows with a significant decrease in daily milk yield at a set temperature-humidity index, THI threshold (68, 72, and 76). The results indicate high variability in somatic cell count due to the animal’s response to heat stress (heat stressed at THI in 68, 72, and 76), parity (1, 2, and 3+), breed (Holstein, and Simmental) and breeding region (Central, and Eastern Croatia). Also, it could be pointed out that Holsteins, especially cows in higher parities (2, 3+) reared in Eastern Croatia were shown to be more sensitive to environmental stress, even in the period after heat stress (1st, and 2nd subsequent milk recording). Since SCC is not only an indicator for mastitis, but also reflects a cow’s immune response to general stress situations, the high variability determined may be explained by the individual adaptation capabilities of these two breeds to breeding conditions in the analysed regions.

The results of the research on the influence of genetic factors on milk productivity and quality composition of milk in the cows at the state farm “Hontarivka” of the Institute of Animal Science, NAAS, Kharkiv region have been given in the article. According to the analysis of variance the factor “line” significantly influenced all indicators of daily milk yields (р < 0,001). However, the degree of the influence of this factor was not high. The factor “line” had the greatest effect on the content of protein in milk – 2.41% and it had the least influence on the somatic cell count in milk. When studying the average physical and chemical values of milk, it was found that the highest average daily milk yield was in the cows of the Hanover line (20.4 kg) and the lowest – in the cows of the Cavaler and Chiff lines (19.6 kg). The cows of Bella line had the best performance as for the content of fat in milk – 4.31%, while the percentage of fat in the milk of Chiff line cows was only 3.98%. The cows of Elevation line had the maximum protein content in milk (3.28%), while the cows of Hanover line had a minimum content of protein in milk – 2.96%. The milk of the animals differed by the somatic cell count, the average content of which varied from 314 000/ cm3 in the milk of cows of the Bell line to 530 000/ cm3 in the animals of the Hanover line. Negative values of the coefficients of the correlation of daily milk yields with the content of fat (–0.225), protein (–0.305), the somatic cell count in milk (–0.134) were obtained. The positive relationship was revealed between the content of fat and protein in milk (+0.282). The low positive connection was also detected between the somatic cell count and the content of protein (+0.061) and the connection with the percentage of fat in milk was lower (+0.021). The revealed dependencies have indicated that the selection aimed at the increase in milk yield should take into consideration the content of fat and protein in milk. However, it does not exert a negative influence on such an indicator of milk quality as the somatic cell count. By the results of the analysis of variance, it has been found that the factor “sire’ significantly influenced the daily milk yield, the content of fat and protein, the number of somatic cells in the milk of their daughters (р < 0.001). Due to the effect of this factor on the daily milk yields the following results were obtained: milk yield – 2.11%, content of fat – 4.21%, the content of protein – 8.2%, somatic cell count – 1.14%. When comparing the average values of the parameters under investigation it has been found that the daily milk yields of some bulls ‘daughters varied from 18.9 kg to 21.2 kg of milk. The daughters of the bull K. Stallion 50750432 were the most productive by the milk yields (p < 0.001), they exceeded by 6.5 – 12.2% the daughters of the bull Chapman 0347903595, Eldorado 579136891, Dante 580024972 and Besson 393035302. As for the content of fat in milk the differences between the best and the worst parameters of the daughters of the bulls under investigation were 0.39%. In this case, the daughters of the sire Benjamin 7866444 significantly exceeded (p < 0.001) the daughters of the sires Besson 393035302 and Eldorado 579136891 by the above parameter. The daughters of the bulls B. R. Harmoni 9498163 and Prento 1402472395 were the best by the content of protein.in milk, they exceeded the daughters of the bulls Belissar 365235897 and Chapman 0347903595 by 0.27–0.35% (р < 0,001). The milk of the daughters of the above bulls was different by the somatic cell count. The average value of this parameter varied from 288 000/ cm3 in the milk of the daughters of Chapman 0347903595 to 530 000/ cm3 in the daughters of Belissar 365235897. The difference between all minimum and maximum average parameters was highly probable (P < 0.001). If we consider the number of cases of diagnosis of mastitis in the daughters of different bulls, then it was proportional to the average values of the somatic cell count in the milk. The incidence of mastitis among the cows ranged from 11.6 ± 2.71% in the daughters of the bull Chapman 0347903595 to 22 ± 4.16% in the daughters of Belissar 365235897. It should be noted that in accordance with the above data the difference between the parameters of the physical and chemical properties of milk and the incidence of mastitis obtained in the cows of different lines was less than that in the daughters of different sires. Therefore, it is advisable to make the assessment and selection by some sires rather than by their lineage.
