“…The general effect of mastitis (higher SCC in the milk) is to impair milk synthesis and loosen the connections between cells (Wheelock, 1980). It was observed that SCC had a high significant effect on milk yield, milk protein, milk lactose, total solids (Cinar et al, 2015). However milk proteins synthesized and DNA in the epithelial cells in the udder decrease.…”

“…Many studies have shown that a negative correlation between SCC in the milk and the milk protein content has been demonstrated (Cinar et al, 2015). The general effect of mastitis (higher SCC in the milk) is to impair milk synthesis and loosen the connections between cells (Wheelock, 1980).…”

“…Despite the technical advances in the milking technique, udder diseases continue to occur very often in many countries of the word (Mrode and Swanson, 1996;Pryce and Brotherstone, 1999;Rupp and Boichard, 1999;Ingvartsen et al, 2003). When the SCC increased, it was seen that milk yield decreased (Petrovska and Jonkus, 2014;Cinar et al, 2015). Due to this fact, it is important to improve the management, husbandry and milking routines, especially the milk removal (RoseMeierhöfer et al, 2010).…”

“…Breed, age, nutrition, and health status of the cow are well known to influence milk yield and composition (Ontsouka et al, 2003;Cinar et al, 2015). However, different cattle breeds vary in average of milk yield and components (Fahr and Lengerken, 2003;Marnet & Komara, 2008).…”

“…Milk yield and milk quality in dairy farms are affected by biological and management factors (Fahr and Lengerken, 2003;Annen et al, 2004;Marnet and Komara, 2008;Dufour et al, 2011;Assan, 2014;Cinar et al, 2015). Cattle breeders are not interested only in getting more milk, but also in having a better milk quality, which increase the basic rates of milk components especially fat and protein percentage and lower number of SCC in the milk (Petrovska and Jonkus, 2014).…”

Milking machine is an important factor in milk performance and milk quality during the course of milk removal in dairy cows. The purpose of the present study was to determine the effect of using quarter individual milking system “MultiLactor” (ML) on improvement of milk performance and milk quality of different dairy cows breeds in different farms. A quarter individual Milking system ML has a single guided tubes with a vacuum of 34 kPa, pulsation rate of 60 cycle/min and ration of 60 to 40%. The system has also a periodic air inlet and a sequential pulsation. In this study, milking data were collected from 170 Holstein Friesian cows (Farm 1), 130 Holstein Friesian (red) cows (Farm 2) and 54 Brown Swiss cows (Farm 3). Quantitative and qualitative milk data of these farms have been recorded by Association of milk records, Switzerland. The primary milking data of cows were collected during the period from 2010 to 2015 after using the new milking system. The data were later processed with Excel program and analyzed using the statistical analysis system (SAS). The results are presented as least square means with standard errors (LSM±SE) and the significant difference was set at (P<0.05). The daily milk yield during the study period from 2010 to 2015 increased significantly to 117% (from 34.64±1.23 to 40.51±1.00 kg/day/animal), 162% (from 20.29±1.37 to 30.88±0.65 kg/day/animal) and 151% (from 15.04±0.83 to 22.71±0.54 kg/day/animal) in farms 1, 2 and 3 respectively after using of ML milking system. Fat and protein content of the milk also increased during the same period of three breeds and farms. However, the results showed that the milking system ML had significant effects on the udder health status by reducing continuously somatic cell count (SCC) in milk by 54.81%, 51.54% and 51.66% in farm 1, 2 and 3 respectively during the study period. Furthermore, Lactation number of the cows were continuously increased in the study during the same period. In conclusion, after 5 years of using ML, it has been shown that a quarter individual milking machine was adapted to the physiological requirements of dairy farms and different breeds and the milk removal with ML brings better quantity and quality of milk in terms of improved milk performance, fat %, protein % and lower number of SCC in the milk.

Relationship between climatic variables and the variation in bulk tank milk composition using canonical correlation analysis

et al. 2018

A number of studies have addressed the relations between climatic variables and milk composition, but these works used univariate statistical approaches. In our study, we used a multivariate approach (canonical correlation) to study the impact of climatic variables on milk composition, price, and monthly milk production at a dairy farm using bulk tank milk data. Data on milk composition, price, and monthly milk production were obtained from a dairy company that purchased the milk from the farm, while climatic variable data were obtained from the National Institute of Meteorology (INMET). The data are from January 2014 to December 2016. Univariate correlation analysis and canonical correlation analysis were performed. Few correlations between the climatic variables and milk composition were found using a univariate approach. However, using canonical correlation analysis, we found a strong and significant correlation (r = 0.95, p value = 0.0029). Lactose, ambient temperature measures (mean, minimum, and maximum), and temperature-humidity index (THI) were found to be the most important variables for the canonical correlation. Our study indicated that 10.2% of the variation in milk composition, pricing, and monthly milk production can be explained by climatic variables. Ambient temperature variables, together with THI, seem to have the most influence on variation in milk composition.
