Fellow goat raiser here's an info shared to us by Michael Rhodes of Mustang Sally Farm.
Mustang Sally is still alive and well in the rural landscape of Negros Oriental and we have no plans to close shop.I did have the herd culled in half and will rebuild the herd up to a 50 doe level again.After breeding our nubians for 5 years with extension line-breeding we realized our gains were so small compared to the amounts of monies and time compared to the value we could realize.In 2010 we made the decision with our consultants to try crossing breeding the snubian over the nubian purebreed.Dairy goats like dairy cattle here in N.America are registered to their respected dairy authority.Goats are under the ADGA,American Dairy Goat Association in North Carolina USA.The production pedigree is a tool that breeders use to select bucks for breeding or if you are planning to buy a doe from a certain bloodline,look at it as the history or roadmap of the bloodline.
All registered herd names are given a set of tattoo numbers and letters,nubians start with NO or NOO with numbers,this can be used to trace the breeder if the name of the goat is unknown.Always in the right ear.Goats enter the DHIR,milk tests,recorded by the ADGA.There is no way for me to put this in simple english,so here goes.
PTA-predicated transmitting ability-data from production and type of the doe,ancestors,collateral relatives and offspring.The first 3 numbers are the estimates of the pounds of milk,fat and protein to expect from each laction of a parents future daughter when compared to a herd mate of breed average genetic merit.The last is the PTA of change to the TYPE score.PTA expresses the level of genetic superiority that an animal transmits to its offspring for a given production or type trait.This value is used to rank animals based on their genetic merit.
example 137M(milk) 2F(fat) 4P(protein) .90T(type)
PTAIndex-means,estimates the extra income a dairyman would receive in each laction based on values supplied by USDA for fat and protein differentials.The first number is fat,the second is protein.Reliability measures confinence in the PTA Values-99 is the highest.An animals reliability is based on the information available in the evaluation.The reliability in this area is for Type.
example 15 13 32R (reliability) in %
PTA%percentage-milk fat(.07) and milk protein (.04).Dates are the last calculation,the first is production and the second is type.The 44R is the line for production reliability.
example 44R (reliability) 6/99 .07 .04 1/01
ETA-estimate of a bucks future PTAs (as an index) for production and type.Production is first,type is second.Zero is no change
example 19 (production) -29(type)
now to put this in simple english-dairy does are evaluated and the data collected is added up for a final score.What can be estimated from future offspring and what the producer can expect in term of added dollar values.
