“…All statistical analysis were performed with the "statistica" program, by applying the Student test (comparison of two means) and calculating the correlation coefficient. Kaouche-Adjlane et al (2020) found that 45% of the samples came from infected udders, effectivelly our results also showed a rate of 53.67% mastitis. Infected udder is a multifactorial disease caused by (milking, nutritional factors, intercurrent pathology (delayed uterine involution) and also they are part of production diseases (Bouhroum and Bensahli, 2016).…”

Background: Among the dairy cattle production problems in Algeria, mastitis rank first in terms of socio-economic impact. Our aim is to identify the state of well-being of the udder in order to manage and control mastitis related problems. Methods: The pH analysis of 177 cow milk samples was performed at two farms located in the Sidi Mhamed Benali region in northwest Algeria associated with an assessment (of the udder’s cleanliness degree, the udder’s position, the teat’s hyperkeratosis lesion and the ITH) out over a period of one year (2020-2021). Result: Analysis of mean (of cleanliness, udder position and ITH) between cold and warm season were significantly different at a value of [(4.11; 2.75); (5.19; 4.11); (56.96; 73.76)] respectively. The paper test revealed that the health of the udder is influenced by any variation in cleanliness and the ITH whose correlation coefficient is equal to 0.72 leading to the appearance of subclinical mastitis during the cold season. While during the hot season the bad milking procedure is incriminated in the appearance of hyperkeratosis lesion at a mean value equal to 1 (smooth ring stage) inducing the appearance of clinical mastitis with p less than 0.05, moreover the cows in first lactation are the most influenced by these elicited factors. In conclusion, monitoring and evaluating the well-being of the udder around the parturition is a tool that allows better prevention of mastitis.

“…The quality of milk is paramount feature for the production of high quality dairy products and essentially for food safety. The previous studies indicated that the presence of cells in the milk at the lower or higher levels can harm its hygienic quality also (Kaouche-Adjlane and Mansour, 2020). Mastitis is usually caused by pathogenic bacteria in the mammary gland however, existence of aseptic or non-specific mastitis is possible (International Dairy Federation 1987).…”

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.
