ABSTRACT: Part 1 of the study described the development of a Hazard Analysis and Critical Control Point (HACCP) based programme and accompanying handbook for the control of mastitis. This paper describes the implementation and evaluation of customised HACCP-based programmes, which were developed from the handbook and assessed on six Irish dairy farms. Both quantitative and qualitative (action research) research methodologies were used to measure the success of implementation and efficacy of control of sub-clinical mastitis as measured by Somatic Cell Counts (SCC) and the degree of compliance by farmers in adopting and maintaining recommendations throughout the course of the study period. No overall differences in SCC before and during the implementation of the study were found when all six farms were considered together. Three of the six study farms experienced a significant decrease in herd milk recorded SCC during the implementation of the control programme. An essential part of the study was achieving initial agreement on recommendations as well as ongoing monitoring of compliance during the study. This pilot study shows that HACCP can be implemented on farms as a means of working towards the control of mastitis and that farmer attitude, and understanding of mastitis are crucial in terms of motivation irrespective of practical approaches used to manage mastitis.

    • "The HACCP-based approach described in the present study offers a logical, structured and formalised approach to mastitis control, which has the potential to be customised for individual dairy farms. The approach developed in this study will be taken to farm-level to assess its practicality and feasibility of implementation [47]. The approach adopted may provide a template for developing a HACCP-based control programme for other infectious diseases of significance to the dairy herd. "

    ABSTRACT: ABSTRACT: Hazard Analysis and Critical Control Points (HACCP) systems are a risk based preventive approach developed to increase levels of food safety assurance. This is part 1 of a pilot study on the development, implementation and evaluation of a HACCP-based approach for the control of good udder health in dairy cows. The paper describes the use of a novel approach based on a deconstruction of the infectious process in mastitis to identify Critical Control Points (CCPs) and develop a HACCP-based system to prevent and control mastitis in dairy herds. The approach involved the creation of an Infectious Process Flow Diagram, which was then cross-referenced to two production process flow diagrams of the milking process and cow management cycle. The HACCP plan developed, may be suitable for customisation and implementation on dairy farms. This is a logical, systematic approach to the development of a mastitis control programme that could be used as a template for the development of control programmes for other infectious diseases in the dairy herd.

    ABSTRACT: Interventions aimed at improving animal welfare on farms may be more successful if greater attention is paid to the points of view of farmers. For example, understanding how different dairy farmers detect lame cows, decide to treat them, get them to the point of treatment, and how practical considerations that impact on this process may be important for reducing lameness on dairy farms. In-depth interviews with twelve dairy farmers were carried out to explore how this occurred on their farms. This in-depth approach allowed a number of factors influencing lameness treatment to be uncovered. The language used by farmers to describe lameness gave important insight into their perceptions of lameness and into the value they placed on prompt treatment. Farmers' perceptions of lameness were found to affect the speed of treatment, with treatment of cows perceived to have impaired mobility or to be less severely lame sometimes delayed. Other priorities on the farm, skilled labour availability, farm infrastructure and farmers' emotional responses to lameness treatment were all found to impact on whether or when a lame cow was treated. In order to encourage farmers to promptly treat all lame cows their perceptions of lameness and the benefits of prompt treatment must be addressed. The language used when communicating with farmers about lameness may be key to achieving this. The practical barriers, such as time and labour constraints, associated with the treatment process, must also be understood, taken into account and seen in the context of the farm management as a whole.

    ABSTRACT: The bovine mastitis can be classified into clinical and subclinical, according to presence or absence of clinical signs. In both cases there is an increase of somatic cells (SC) being higher for clinical mastitis. The purpose of this study was to determine the effect of subclinical mastitis on physical and chemical milk components in dual purpose systems (DP). Using a non-probabilistic sampling in six DP livestock enterprises in Monteria, Cordoba (Colombia), a cross-sectional study was implemented. By California mastitis test (CMT) were selected quarters evaluated as CMT 3 to take samples, and quarters evaluated as CMT 0, in the same cow, for control. The samples were collected aseptically and were kept refrigerated until processing. The physicochemical analysis was determined by Biolac 60 equipment. The determination of casein was done by spectrophotometry, and SC count by an optical and portable cell counter. The evaluation of the physicochemical variables and SC count were grouped into four phases (0-2 months, 2-4 months, 4-6 months and more of 6 months of lactation). Milk with cell count less than 250,000 was defined as without subclinical mastitis and with subclinical mastitis when cell count was greater than or equal to 250,000 SC/mL. The averages for total protein for milk with high and low SC counts were 2.93 +/- 0.13 and 3.12 +/- 0.13, respectively. For fat percentage, averages were 3.36 +/- 0.29 for high count milks SC and 3.70 +/- 0.46 for milk with low count of SC. Overall, milk with high counts of SC, the chemicals components decreased significantly (P <= 0.05) compared to the low count of cells.
