The world dairy cattle industry has advanced, but in Brazil, the quality of milk is a barrier to the strengthening of the chain. Thus, the objective of this research was to institute an action plan in ten dairy farms in the southern region of Brazil, which produced low quality milk, and to monitor changes in quality and economic gain, during one year. Critical points were identified and an action plan based on good agricultural practices and mastitis control was instituted. Monitoring consisted of collecting and analyzing milk samples for levels of fat, protein, somatic cell count and standard plate count. After twelve months, there was an increase (p<0.05) in the levels of fat and protein and a reduction (p<0.05) in the somatic cell count and in the standard plaque count. The action plan improved the quality of milk and, therefore, reduced the disposal of milk in the environment, and increased the profitability of the properties studied.

Quality Of Milk

The aim of the study was to analyse the effect of the housing system (tie-stall vs free-stall) on cow cleanliness, and the effect of the degree of cow dirtiness on the milk somatic cell count. Over 33% of the cows were found to be clean, with more of them in the free-stall barn. Analysis of the cleanliness of body parts showed that the highest hygiene level was characteristic of the udders and underbelly (scores of 1 for 47% and 56% of the cows, respectively). In the free-stall barn, there were over twice as many cows with clean udders (58%) and almost twice as few cows with very dirty udders. Regardless of the housing system, the degree of udder dirtiness created differences (P ≤ 0.01) in the natural log somatic cell count. The natural log somatic cell count increased from 11.54 to 12.37 on average with increased dirtiness of the udder. Greater differences in the cytological quality of milk were found in cows housed in the free-stall system. When analysing the effect of overall dirtiness of the cows and the body parts on the percentage of SCC classes, it was found that highest quality milk (< 200 000 somatic cells/ml) was produced by clean cows (71.52%). The proportion of cows with subclinical and clinical mastitis was found to increase with decreasing cleanliness of the udder, especially in the free-stall system. Overall, the proportion of cows with clinical mastitis increased from 2.51% (clean cows) to 14.29% (dirty cows).

Quality Of Milk

The somatic cell count (SCC) is commonly used as a measure of udder health and milk quality. Thus, to determine the milk quality standards in many countries, it legally determined as an indicator of somatic cell count raw milk and determines the level of payments to milk producers. The present study investigated that the somatic cell count is an indicator of udder health status, diagnosis of subclinical mastitis, health and quality of milk and milk products, its importance and effect factors on it.

Quality Of Milk

Background: Infectious diseases and metabolic disorders are common in crossbred cows and adversely affect optimum production as well as quality of milk. The quality of milk plays a significant role in the production of high-quality dairy products. High somatic cell count (SCC) in the milk significantly decreases the potential of such milk for the production of high quality dairy products. In this study, it is hypothesized that the extra-mammary infections and metabolic disorders increase probability of intra-mammary infections thereby increasing somatic cell count in the milk making it unsuitable for dairy industry.Methods: Cows were grouped based on the diseases or disorders like Teat Stenosis (Gp SCM-TS), Ruminal Acidosis (Gp SCM-RA), Nonspecific Diarrhea (Gp SCM-ND), Respiratory Tract Infections (Gp SCM-RTI) and Repeat Breeder Syndrome (Gp SCM-RD). Diagnosis of subclinical mastitis was made on the basis of California Mastitis Test (CMT) scores and by Somatic Cell Count (SCC) by automatic somatic cell counter. Biochemical parameters analyzed in automatic biochemical analyzer using commercially available kits.Result: The mean SCC values significantly higher in cows with sublinical mastitis and with concurrent infectious and metabolic diseases. Similarly, the concentrations of serum alkaline phosphatase (ALP), aspartate amino transferase (AST), and alanine amino transferase (ALT) were higher in affected cows. Concentrations of serum total proteins (TP) and blood urea nitrogen (BUN) in all the groups of affected animals were higher. The changes in the calcium (Ca) and phosphorus (P) levels were not observed in cows with subclinical mastitis and with other diseases under study. The SCC values did not correlate with the values of ALP, AST, ALT, TP, BUN, Ca and P among the studied groups. It can be concluded that animals with concurrent infections and metabolic disorders increase the SCC and influence the alteration in the biochemical parameters of subclinical mastitic animals.
