The study aimed to verify the influence of different milking machine setting parameters on Italian Mediterranean buffalo milking performance. Data on milking machine settings (Milking Dry Tests [MDTs]) and milk Test-day (TD) were collected by the Italian Breeders Association (AIA). Data for each TD consisted of milk yield (MY), fat percentage (FP), protein percentage (PP), lactose percentage (LP) and linear score (LS). Working vacuum level (VL), pulsation ratio (PR), automatic cluster removal system (AC) and effective vacuum reserve (EVR) were recorded from each MDT. A total of 558 MDTs, 217,967 TD, collected from 43,593 buffaloes in 198 buffalo farms were utilised. MDT, TD and Animal data (AD) were analysed through a mixed linear model and a logistic regression model was used to evaluate the relationship between VL and EVR. Analysis of MY and quality revealed that an incorrect setting of the milking was responsible for a higher LS and lower MY and LP, along with higher FP and PP compared to farms with adequate EVR. Except for PP, the height of the milking system significantly influenced all milk parameters. Conversely, VL affected all milking traits. A higher PR (70:30) was responsible for significantly lower LS and higher FP compared to a 60:40 PR. Similarly, the presence of AC showed a significant effect on FP and MY and a slight reduction in LS. Finally, the diameter and length of the pipeline (DL) ratio lower than 2.5 m was associated with a decrease in LS. These results suggest that buffaloes require specific milking parameters. Buffalo has a specific requirement for milking parameters. Incorrect milking setting increase somatic cells and reduce lactose content. Vacuum level (VL) affects milk yield (MY) and quality as well as somatic cells and lactose. [ABSTRACT FROM AUTHOR] |
