what is classification?

• assessment of external physical characteristic

areas of classification

• rump

• mammary

• dairy strength

• feet and legs

the program

• 28 descriptive traits

• 15-26 defective characteristics

• 4 scorecard categories

• overall final score

scores

• excellent: EX

• very good: VG

• Good plus: GP

• good: G

• fair: F

ideal rump

• well sloped, wide, strongly anchored to the back

• links to fertility and calving traits in females

ideal mammary

• udder is soft, wide and high, strongly attached with ideal teat length and placement

• highly correlated with production traits

• positive correlation her life and mastitis resistance

idea dairy strength

• cow is well sprung, open ribs with adequate width of chest

• moderate correlations with production traits

• forage consumption and organ function

ideal feet and legs

• conformation consists of widely placed straight fine boned legs with a long straight stride and with feet that have a deep heel depth that are square under cow

• linked with mobility

• highly correlated with production, hoof health, and herd life

classification and genetics

• tool to identify problems cows

• insight into how herd is tracking to tits goals and where emphasis needs to be placed

• feeds into animals ranking automatically, which allows most accurate rankings of milking animals

classification and genetics: bulls

• foundation for genetic evaluations for sire proofs

• linear score used to calculate evaluations for conformation traits

• reliable genetic evaluations rely on continued collection

goal of lactanet

help producers with:

• production and components

• herd health

• milk quality

• forage and feed

• finance

DPT’s role

• visit dairy farms dailt to sample milk, collect data, promote lactanet services

• assist and provide info to customers about interpretation and application of data

• arrange administrative, travel, and scheduling tasks

• actively participate in the job training

facts, stats and trands

• average DHI herd size

• market share trends

• robot stats

why do robot herds test

• add value to daily robot info

• components such as fat/protein/SCC

• health testing thru milk sample

• publishable records

• genetic info shared

• benchmark with other herds

electronic DHI

• convenient

• lower cost

• long term herd trends, milk value, etc

• benchmarking

• genetic indexes

• data

dairy comp supplies

• % of DHI cows

• non-DHI herds

popular reports from lactanet

• johnes

reasons farmers dont use the herd reports

• get data from their robot

• get data from bulk tank

• herd is perfect

• costs too much

• dont read reports

6 section in herd report

• standard milk graph

• stage of lactation

• lactation group profile

• lactation rating

• production averages

• test day summery

selective dry cow therapy management tool

• reduces use of antibiotics

• herd and cow level evaluation

• connecting with vets in advance

• added value for individual cow sampling

herd management tools for 2026

• TMI

• mobile

• feedcomp

• canadian dairyhub

feed efficiency genetic index

• identifies animals with feed efficiency superiority

• free for females in DHI

methane efficiency genetic index

• identifies animals with lower methane production

• will reduce methane by 20-30%

• available for select AI sires

• free for female sin DHI herds
