Yesterdays challenge is also a challenge today, - but the scene is different! Feeding ! Reproduction ! Health !
The challenges… Feeding • Correct digestibility and structure • Correct energy/protein supply • Minerals and vitamins Reproduction • Heat detection • Pregnancy determination • or estrus synchronization…. Health • Metabolic diseases • Mastitis • Reproduction disorders
On farm solutions, - examples! Afilab milk analysis analyzes: • Fat • Protein • Lactose • Blood in milk • 4 levels for somatic cells • Additional application for monitoring metabolic disorders
On farm solutions, - examples! HeaTime/RuminAct • Distributed by several breeding organizations • Transponder with activity meter and microphone • Registers: • Heat • Lameness • Acidosis and predecessors • Monitor effect of treatments and ”wellbeing”
On farm solutions, - examples! • Herd Navigator • Distributed by Delaval • Analyzes four parameters in milk using drystick technology • Monitors parameters within • Reproduction • Mastitis • Metabolic disorders • Nutrition • Biological models process data as they appear and issue alerts
Reproduction, what is registered? • Cycling, - or not! • Heat • Pregnancy • Prolonged anestrus • Cysts (follicular as well as luteal cysts) • Abortions Basically the progesteron level is monitored!
Herd Navigator Attention List Cow ID Prog. level Reprod. status Lact. Stage & no 7 days milk yield Days since insemination Standard Operating Procedure Number of inseminations Likelihood of success of insemination Sampling, date and time
Standard Operating Procedures! • Fixed procedures for an incident or activity • Necessary in big herds! • A brilliant idea in all herds! • Must be implementable in the herd management system!
… More knowledgecreate new questions! And the laboratories will feel the competition from on-farm analyses! In this crossfire new business opportunities emerge! The labs launch new services - this can create value for the milk producers!
Upcoming opportunities! • All DHI samples can now be screened for ketosis ! • This allows detection of a potential herd problem • Cows <60 DIM are at risk!
Upcoming opportunities! • Now relevant DHI samples canbeanalyzed for all major mastitisbacteriawithin 4 hours! • Cows < 60 days and at dry offarecritical to monitor ”By March 1st 2012, 5 months after introducing the service in Denmark, 40 % of tests before drying off were made by PCR tests!” J. Katholm at DCF annual meeting
Upcoming opportunities! • Pregnancy can now be confirmed on DHI samples! • Relevant 30 – 40 days after insemination and before drying off
The future of DHI programs? • Milk recording serves two purposes • Breeding aspects • Few samples per lactation are needed • Herd management, • More samples must be analyzed ! • Appropriate timing! • This does not necessarily mean monthly or bi monthly sampling of all cows!
An example • 10.000 cows, 10.000kg/cow, SCC<100.000 • No DHI service! • Monthly metering! • Regular monthly visit from consultants • Own lab • All info entered into DairyCOMP • They are already doing most of the job!! Think of all the info they could get to further optimize the feeding! And think of all the breeding information lost if this becomes the trend!
Suggestions! • Work for more flexible sampling schemes! • As often as feasible first 60 DIM • Less frequently the remaining part of the lactation • Work for more flexible sampling devices on farm! • Would enable smaller herds to focus on sampling fresh cows • Would allow more samples on specialized parameters In big herds fresh cows are all in the same group(s)
Summary! • Increasing herd sizesdemands new tools to monitor and manage herds! • On farm tools, someanalyzingmilk, arecoming up for good! • Turning data intoreccommended action is crucial! • The lab routine analyses of tomorrow will be different from those of today! • More flexibility in the sampling procedure canassist in thisprocess! • DHI labs and associatedconsultants must focusonbringing more value to the farm
