YANCO Summary U Heifers

This is a simple summary document to monitor the data for each methane trial. The goal is to get at least 30 records with a duration of more then 3 minutes.

The summary for the units currently @ YANCO is:

Time on test:

#Pen Summary

## Time difference of 41 days

Box plots of summarised data

After cleaning for outliers per individual (3 SD from individual’s mean)

##Cupdrop pattern across groups

##Cupdrop pattern across Breeds

##Total animals measured in the groups by breed

##Total animals visiting by weight class

##total animals missed per group by breed

The following table represents cupdrops over the trial period (similar to what is seen on the C-Lock website)

Cupdrops per animal per day

##number of animals visited for 2 or more days since trial recording began

## [1] "number of animals visited for 2 or more days since trial recording began"
## [1] 106

##Histogram of number of visits since trial recording began

Note: position 1 - back of the trailer has one extra feeder position 0 = unit 463

##Trailer preference

##Animal Summary

The following Graph shows the number of animals and the cumulative number of records (greater than 2mins). ie. 4 animals with 10-15 records

## [1] 120.9808

##tracking usage over time

the following plots are an attempt to track usage over time. The first plot is a histogram of usage over the day in minutes - 500 minutes = 08:20 1000 = 16:40

##histogram of data usage over time

##histogram of times of cupdrops of animals with more than 32 2min methane records AKA “PIGS” and less than 15 2min methane records AKA “SHY FEEDERS”

##Boxplot of Pigs and Shy Feeders - mean 25 AND 75 percentiles

This is a histogram of visitation over the day. Time is in minutes - 1440 minutes in a day

Interesting pattern forming here. We need to check if animals have patterns it would be good to see if machine usage is different for different groups of animals - pigs vs shy feeders. Potentially we may need manage usage over the day a little
