“…In spite of these variations, all farms exhibited similar response in increased milking frequency. The outline of variations in milk yield with increasing milking frequency observed in this study is steady with similar previous assessments [17] in conventional systems. The present study clearly showed the milk yield promoting effect of milking frequency in Korean Holstein dairy cows.…”

ObjectiveThe aim of the current study was to describe the relationship between milk yield and lactation number, stage, length and milking frequency in Korean Holstein dairy cows using an automatic milking system (AMS).MethodsThe original data set consisted of observations from April to October 2016 of 780 Holstein cows, with a total of 10,751 milkings. Each time a cow was milked by an AMS during the 24 h, the AMS management system recorded identification numbers of the AMS unit, the cow being milking, date and time of the milking, and milk yield (kg) as measured by the milk meters installed on each AMS unit, date and time of the lactation, lactation stage, milking frequency (NoM). Lactation stage is defined as the number of days milking per cows per lactation. Milk yield was calculated per udder quarter in the AMS and was added to 1 record per cow and trait for each milking. Milking frequency was measured the number of milkings per cow per 24 hour.ResultsFrom the study results, a significant relationship was found between the milk yield and lactation number (p<0.001), with the maximum milk yield occurring in the third lactation cows. We recorded the highest milk yield, in a greater lactation length period of early stage (55 to 90 days) at a 4× milking frequency/d, and the lowest milk yield was observed in the later stage (>201 days) of cows. Also, milking frequency had a significant influence on milk yield (p<0.001) in Korean Holstein cows using AMS.ConclusionDetailed knowledge of these factors such as lactation number, stage, length, and milking frequency associated with increasing milk yield using AMS will help guide future recommendations to producers for maximizing milk yield in Korean Dairy industries.

“…This fact was shown in a study that total solids, fat content, and milk pH decreased by increasing milking interval, showing the greatest value at 8-hr intervals and the lowest at 24-hr intervals [32]. Similar results were obtained by Alshaikh and Salah [33] that the organic component of camel milk such as Fat, Protein, Solids-not-fat (SNF) and Lactose decreased with increasing milking intervals and concurrently the secretion rates of milk was decreased. Moreover, the results indicated that the fat content in the milk increased continuously with advanced stage of lactation.…”

Camel milk is considered one of the most valuable food sources for people in arid and semi-arid areas and is in increasing demand in many European countries and North America. The objective of this study was to investigate the camel milk composition, udder health and effect of different storage times and temperatures on raw milk quality using camel milking machine "StimuLactor" (ST-C). This work was carried out in the department of research and development of Siliconform Türkheim, Germany. Five one-humped dromedary lactating camels were used in this experiment. Milk samples were collected and fat, Protein, Lactose, Somatic cell count (SCC) and Bacterial count (BC) were determined. In none of the tested milk samples pathogenic bacteria could be shown, i.e. all quarters were healthy during the study period. The mean contents of fat, protein, lactose, SCC and BC of milk samples were 2.92±0.07%, 2.28±0.01%, 3.91±0.02%, 126.43±7.21 x 103 cells/ml and 23.88±0.57 x 103 Bacteria/ml, respectively. After 24 h at room temperature or 48 h at 4 degree a refrigerator, storing raw milk samples had no significant changes in the milk composition and-quality. In Conclusion, a good safe raw camel milk with normal composition was obtained if hygienic measures were taken into consideration in the farm and by using the camel milking machine for milk removal. Furthermore, we could store the raw camel milk for 24 h at room temperature or for 48 h in the refrigerated temperature without any hygienic quality problems, and all milk components did not significantly change.
