Milk Fat to Protein Ratio and Somatic Cell Count in Bulk Milk of Dairy Farms in Upper Northeastern Region
Khon Kaen Veterinary Annual International Conference (KVAC) The 18th

• Milk compositions can be used to indicate health status and imbalance of feed
• Fat, Protein, Fat to protein ratio (FPR)
Introduction
Imbalance of feed
Risk of diseases metabolic disorders (ketosis, acidosis), lameness , DA, reproductive problem and mastitis
• Use to indicate
FPR = Percentage of milk Fat
Percentage of milk Protein
Heuer et al., 1999
(Eicher, 2004)
• Bulk milk somatic cell count (BM SCC)
Monitor mastitis in dairy herd
• SCC Excellent marker for subclinical mastitis

Introduction
1.0 1.3
Lack of fiber
Normal
Ketosis
FPR uses to indicate health status
Optimal range Lower range Higher range
NEB (lack of energy)
• Both a lower and a higher FPR increased the risk of mastitis (Windig et al., 2005)
Mastitis
Mastitis
Acidosis
Introduction
Garciaa et al., 2015 Gantner et al., 2016
The objectives of this study
• BM quality in Upper NE (2013-2016)
• Association between FPR and SCC
• BM data of dairy farms in Upper NE (2013-2016)
• A total of 40,272 milk records 21/185 MCC
Materials and Methods
Materials and Methods Milk Quality
• SCC (x103 cells/ml)
• % Fat, Protein, Lactose, SNF, and TS
Fossomatic 5000 basic®
MilkoScan FT6000®
Cut off values
*Heuer, 2010
• 2-20% TS1
• 2-10% Lactose1
• 2-9% Fat12 and Protein12
• 100x103 - 1,500x103cells/ml SCC1
1Performance range test of Automatic analyzers (Combifoss, Denmark) 2

(Veterinary Research and Development Center)
• FPR was classified into three groups
• < 1.0
• 1.0-1.3 (optimal range)
• >1.3
Association of FPR and SCC using Kruskal Wallis Test
(Garciaa et al., 2015)
(Gantner et al., 2016)
Materials and Methods
• Descriptive analysis milk quality
Results and Discussion
FPR of individual cows 1.18 (Puangdee et al., 2016)
Results and Discussion
Strong policy on milk quality which resulted in a better milk composition
15.5% <1.0 11.8% >1.3
72.7% in optimal range
1.0-1.3
Results and Discussion
(Garciaa et al., 2015)
(Gantner et al., 2016)
Results and Discussion
Conclusion
• The BM SCC was significantly increased
when FPR was high
