Process an index with sale as finished cattle

func EvaluateWeaningIndex

func EvaluateWeaningIndex(nYears int, burninMarker int, param map[string]interface{}, gvCholesky mat.Cholesky, rvCholesky mat.Cholesky) float64

Process an index with sale at weaning

func InitGrid

func InitGrid()

If slaughtercattle IndexType then initialize grid pricing

func InitIndexParams

func InitIndexParams(indexParam *string)

Read the index hjson file

func IsInIndex

func IsInIndex(b animal.Component_t) bool

Is this in the index

func IsIndexTerminal

func IsIndexTerminal() bool

func LoadIndexComponents

func LoadIndexComponents()

Setup the index traits

func ProcessNetReturns

func ProcessNetReturns(indexParam *string, nYears int, burninMarker int,
	param map[string]interface{}, gvCholesky mat.Cholesky, rvCholesky mat.Cholesky)

main call

func SetActiveCowList

func SetActiveCowList()

// Reset Records back to heifers

func HeiferReset() {
	for i := range animal.HeiferResetList {
		animal.Records[i].Sex = animal.Heifer
		animal.Records[i].BreedingRecords = nil
		animal.Records[i].Dead = 0
		animal.Records[i].YearCowCulled = 0
		animal.Records[i].Active = false

	}
}

// Reset Records back to active cows

func CowReset() {
	for l := range animal.CowResetList {
		i := animal.CowResetList[l].Id - 1
		animal.Records[i].Sex = animal.Cow
		animal.Records[i].BreedingRecords = nil
		animal.Records[i].Dead = 0
		animal.Records[i].YearCowCulled = 0
		animal.Records[i].Active = true
		animal.Records[i].BreedingRecords = animal.CowResetList[l].BreedingRecords
	}
}

func WeaningNetReturnsToFixedCosts

func WeaningNetReturnsToFixedCosts(nYears int) float64

The total discounted net returns to fixed costs for weaning

and optionally write a table to stdout Returns average cost/mating

func WeaningVariableCostsPerMating

func WeaningVariableCostsPerMating(nYears int) float64

This is used to caalculate the weaning costs per year for all indexes except weaning, because weaning does it below in the net returns calculation.

func WhatSaleEndpoint

func WhatSaleEndpoint() (indexType string)

Return the type of index the hjson builds

Types

type GridValue_t

type GridValue_t struct {
	QualityGrade string // Prime, Program, Choice, Select,Standard

}

type TraitSexMinWtMaxWt_t

type TraitSexMinWtMaxWt_t struct {
	Trait         string  // Same as traits in master hjson - e.g., WW is weaning weight
	Sex           string  // Sex S=steer and H=heifer calf
