Below is a list of the different effect analyses available in PigVision and what they analyse for. 

 

Heat:

These analyses can only be used if you do "Heat observation". 

  •  Heat top
    • The top of the heat compared to the start of the heat compared to ovulation time. 
  • Heat start litter no.
    • Heat start compared to litter no. and heat duration
  • Heat start ovulation 
    • Heat start compared to heat duration and ovulation time
  • Suckling per heat start
    • Suckling period duration compared to heat start, heat duration, and litter no.
  • Score heat duration
    • Changed score during suckling period (if registered) compared to heat duration and litter no. 
  • Score heat start: 
    • Changed score during suckling period (if registered) compared to heat start and litter no. 
  • Litter No. heat start
    • Litter no. compared to heat start, heat duration, and ovulation time 
  • Service time ovulation 
    • Heat time compared to service time (if registered) and ovulation time 
  • Back fat heat start
    • Change in back fat in suckling period (if registered) compared to heat start and litter no. 
  • Back fat heat duration
    • Change in back fat in suckling period (if registered) compared to heat duration and litter no.

  • Gestation litter no.
    • Gestation period compared to litter no. 
  • Still born
    • Still born compared to week day for farrowing and the employee
  • Still born previous litter: 
    • Still born in previous litter compared to live born and litter no. of the following litter 
  • Week day
    • Farrowing day compared to employee and location 
  • Live born
    • Live born compared to week day and employee 
  • Live born previous litter
    • Live born in previous litter compared to still born and litter no. of the following litter 
  • Location
    • Location of the farrowing compared to employee and week day 
  • Breed
    • The sow breed and its effects on farrowing results 
  • Backfat score
    • Back fat and score during the farrowing and their effects on farrowing results  
  • Mummified
    • Mummified pigs compared to litter no. 
  • Weak born
    • Weak born pigs compared to litter no 

 

Distribution graph

  • This is not analyses per se, but rather graphs showing the effect of certain actions such as the number of sows with a specific suckling period duration compared to the litter no. 

 

Weaning

The effect the previous weaning has on the following litter

  • Nursing sow previous litter
    • Whether or not the sow was a nursing sow compared to gestation period and total number of weaned pigs in the next litter 
  • No. final weaned pigs
    • No. of weaned pigs from the final weaning compared to gestation period and litter no. of the following litter 
  • No. total weaned pigs
    • Total no. of weaned pigs compared to gestation period and litter no. of the following litter 

 

Gilts

How gilt services affect gilt results 

  • Age at 1st service: 
    • The age at 1st service compared to whether or not the gilts got pregnant. Also sorted by employee 
  • Heat no. 1st service: 
    • The heat no. when the gilt was serviced compared to the pregnancy result and age at 1st service 
  • Gestation period mummified: 
    • The gestation period compared to no. of mummified and weak born pigs 
  • Gilt services: 
    • Whether or not a service lead to a pregnancy compared to employees 
  • Entry to 1st service: 
    • Time from entry to 1st service compared to whether or not the service lead to a pregnancy, heat no., and age at 1st service 

 

Service

  • Semen age concentration
    • The age of the semen compared to whether or not it lead to a pregnancy compared to semen concentration 
  • Employee 1,2,3
    • Employee a 1st service compared to employees at 2nd and 3rd service 
  • Heat intensity
    • Heat intensity at time of service compared to whether or not the service lead to a pregnancy as well as service score
