The aim of this study was to determine the factors affecting mastitis cases and to estimate the correlations of somatic cell count (SCC) with milk yield in Holstein cows. The study was conducted in two private dairy farms in Hódmezõvásárhely, South-Hungary. A total of 882 Holstein cows were tested by SCC, fat and protein contents of milk monthly intervals. To test milk SCC and components, two groups were designed, and to examine effect of parity on first mastitis day (FMD) and total mastitis cases (TMC), four groups were divided. It was noted that higher SCC caused to higher TMC. While cows had higher protein content exposed to higher FMD and TMC, cows had lower daily milk yield (DMY) had higher values by mastitis case parameters. In parity evaluation, only primiparous cows had statistically lower TMC. The cows with lower SCC were found in advance in change of milk yield (CMY) up to 6.858±0.947 kg. A negative correlation coefficient was estimated between SCC and DMY. Finally, monitoring SCC of milk is offered to prevent milk production losses and new mastitis occurrences in the herds.

This study was carried out to investigate the effect of udder measurements group on somatic cell count (SCC) and daily milk production. Milk samples and udder measurements were collected monthly from 79 lactating Holstein cows on commercial dairy in the province of Niğde. In the study, front teat length (FTL), rear teat length (RTL), front teat diameter (FTD), rear teat diameter (RTD), distance between front teats (DBFT), distance between rear teats (DBRT), front udder height, (FTH), rear udder height (RUH), distance between front and rear teats (DBST) were obtained in before afternoon milking. Udder measurements were divided into 5 groups according to the measurements. The effect of DBFT, DBRT, FTH, RTD, FTD and DBRT groups on daily milk production were statistically significant, while FTH, RUH and DBRT were found non-significant. The effect of udder measurements groups on SCC was found not significant, except rear teat diameter (RTD). Average daily milk production and SCC were estimated as 28.25 kg/day and 274.90 cell/ml, respectively. In conclusion, it can be said that the distance between teats, teat’s diameter and front udder height of Holstein cattle is important factor for milk yield of Holstein dairy cattle. Also, SCC is effected by rear teat diameter.

Production Traits

The aim of this work was to evaluate the genetic status of the Girgentana goat, an endangered breed from Sicily (Italy), using microsatellite markers. Furthermore, as the main purpose of the Girgentana breed is milk production, quantitative milk traits were investigated, including fatty acid profile. Molecular data from CSN1S1, CSN2, CSN1S2, and CSN3 casein genes were also used to infer haplotypes. A total of 264 individuals were collected. Samples of Maltese (n = 41) and Derivata di Siria (n = 33) goat breeds were also used to understand the genetic relationship among breeds. Test-day records for milk production were collected to determine daily milk yield, fat, protein, casein, lactose, and somatic cell count. Individual milk samples were also collected for fatty acid extraction. Wright’s statistics, gene flow, Nei genetic distance, factorial correspondence analysis, and Bayesian assignment test showed the existence of genetic variability and differentiation among breeds. The AMOVA results indicated that 89.96% of the total variance was partitioned within populations. The Girgentana breed appears to have a subdivided population, and has not experienced a recent bottleneck. A high variability in milk yield was observed. Mean morning milk yield was 1448 ± 404 g, with 4.30 ± 0.87% and 3.72 ± 0.44% of fat and protein percentages, respectively. The average somatic cell count found in Girgentana goat milk was higher than the threshold of 1 500 000 cells/mL advised in Europe for fresh milk. Gross milk and fatty acid composition were similar to that reported in the literature for other local goat breeds.

Teat Dipping

This study was aimed to compare somatic cell count and milk production on dairy cattle after teat dipping post milking application. Samples collected from total of 121 quarters of dairy cattle in normal lactation period and identified as infected by subclinical mastitis. Subclinical mastitis examination was done by IPB Test Mastitis Test, somatic cell count calculation was done by Breed Method, and observation of milk production was done by calculating milk volume per quarter. Observations were performed during normal lactation periods of 12 weeks. Data were analyzed statistically using Mann-Whitney Test and unpaired t-test. The results showed that the number of somatic cells count in the treatment group with post milking teat dipping application was lower than in the control group and significantly different at week 11 (p = 0.039). Furthermore, the volume of milk production in the treatment group was higher than in the control group and significantly different in almost all weeks of observation (p<0.05). It was showed that post milking teat dipping application can prevent subclinical mastitis infection effectively, seen from low somatic cell count (below 400.000 cells/ml) and can maintain optimum milk production. So that, this application can increase the economic benefits for dairy farmers.
