Slide 6

TYPICAL DEMONSTRATION PROGRAMME

  • ABOUT TWO HOURS AFTER MILKING 80-100 LITRES OF COW MILK (ALSO BUFFALO MILK IN PAKISTAN) WAS COLLECTED AND DELIVERED TO MEETING PLACE

  • MILK WAS TESTED BY SENSORY, LACTOMETRE, ALCOHOL (68%), COB, ACIDITY AND pH TESTS

  • MILK WAS FILTERED AND DIVIDED INTO TWO MILK CANS, ONE WAS LP-s TREATED, OTHER ONE WAS CONTROL. PARTICIPANTS WERE ASKED TO SELECT THE CANS

  • MILK CANS WERE KEPT IN AMBIENT TEMPERATURE UNTIL TECHNICAL TRAINING WAS OVER (ABOUT 5-8 HOURS FROM ACTIVATION)

  • LECTURES IN THEORY AND HISTORY OF LP-s, OUTLINES OF CODEX GUIDELINES, HYGIENIC MILKING, MILK HANDLING AND COLLECTION AS WELL AS SIMPLE QUALITY TESTING WERE GIVEN

  • FLOOR WAS OPENED TO PARTICIPANTS FOR DISCUSSION

  • MILK CANS WERE OPENED AND SAME TESTS (EXEPT DENSITY) WERE PERFORMED AS IN THE MORNING

Slide 13

MOST COMMON QUESTIONS

  • WHAT IS THE COST OF LP-s TREATMENT?

  • WHERE THE ACTIVATORS ARE SOLD?

  • CAN ACTIVATORS BE MANUFACTURED LOCALLY?

  • WHEN IT WILL BE POSSIBLE TO START USING LP-s?

  • HOW AND WHEN MCP FOR LP-s CAN BE ESTABLISHED?

  • WHAT HAPPENS IF ACTIVATOR No 2 IS ADDED FIRST?

  • HOW TO APPLY LP-s TO MILK QUANTITIES LOWER OR HIGHER THAN 40 -50 LITRES?

  • IS IT POSSIBLE TO GET ACTIVATORS FOR SMALLER MILK QUANTITIES THAN 40-50 LITRES?

  • IT IS POSSIBLE TO REACTIVATE LP-s AFTER 7-8 HOURS?

  • WHY LP-s CANNOT BE USED ON INDIVIDUAL FARMS?

  • IS THERE ANY HARM TO HUMAN HEALTH?

  • DOES LP-s TREATMEN AFFECT MILK PROCESSING?

  • HOW LONG TIME LP-s MILK KEEPS AT AMBIENT TEMPERATURES HIGHER THAN 30°C?

Slide 14

PROBLEMS

  • QUALITY DIFFERENCE BETWEEN LP-s AND CONTROL MILK WAS NOT CLEAR DUE TO REASONS LISTED BELOW:

    • MILK WAS KEPT IN TOO HOT PLACE (PAKISTAN)

    • MILK WAS COOLED DOWN AFTER MILKING

    • MILK WAS PRODUCED UNDER VERY HIGH HYGIENIC CONDITIONS

    • MASTITIS MILK -MILK CONTAINED ANTIBIOTICS

    • NEUTRALISERS LIKE CAUSTIC SODA WAS ADDED

    • COWS WERE FED FEED CONTAINING - SCN PRECURSORS LIKE CASSAVA (INDONESIA)

    • DELAYED ACTIVATION OF LP-s (BHUTAN)

    • LONG LASTED HOT AND DRY SEASON COMBINED WITH HIGH HYGIENIC QUALITY: MILK MICROFLORA CONTAINS LITTLE ACID FORMING BACTERIA (THE PHILIPPINES)?

Slide 15

NOTES

  • EACH COUNTRY FINALISED NATIONAL ACTION PLAN FOR FUTURE USE OF LP-s IN FINL PROJECT WORKSHOP

  • NATIONAL LP-s DEMONSTRATIONS IN THE PHILIPPINES AND VIETNAM WERE CARRIED OUT 2004

  • CODEX ALIMENTARIUS GUIDELINES ON LP-s HAS BEEN ADOPTED BY BANGLADESH STANDARD AND TESTING INSTITUTE (BSTI)

  • MANY COUNTRIES ARE CONSIDERING TO START OWN PRODUCTION OF LP-s ACTIVATORS

Slide 16

ISSUES RAISED

  • Importance of small-scale dairying

  • Need for milk preservation techniques

  • National decisions on milk standards

  • Research papers to support LP-s for consideration by national health authorities

  • Use and control of LP-s

Slide 17

CONCLUSIONS

  • THERE IS GOOD POTENTIAL TO START USING LP-s IN THESE COUNTRIES FOR FOLLOWING REASONS:

    • HOT CLIMATE CONDITIONS

    • POOR INFRASTRUCTURE (ROADS, ELECTRIC SUPPLY, MILK COLLECTION SYSTEMS)

    • LONG TRANSPORT DISTANCES (PAKISTAN)

    • TO FACILITATE COLLECTION OF EVENING MILK

    • TO REDUCE MILK COLLECTION AND TRANSPORT COSTS

    • TO REPLACE UNHYGIENIC AND HARMFUL USE OF "HOMEMADE" MILK PRESERVATION METHODS LIKE ADDING ICE DIRECTLY IN MILK, USE OF HYDROGEN PEROXIDE, FORMALIN ETC AND NEUTRALISERS

    • TO OPEN NEW MILK COLLECTION AREAS
