PEISCHEL, continued from Page 8 looking at goats (Kiko, Cashmere, Angora), gorse and hiking (climb- ing) the steep hill country was what I expected (strenuous). What was most impressive was climbing steep slopes on the station where most of the Kikos were out performing noxious plant eradication. It was an ugly day with rain blowing horizontally but when we came to the top of the incline, there was a mob of Kiko kids out strip- ping gorse, oblivious to the weather. We stood for a long time in our ‘dry-as-a-bone’ raingear, backs to the weather, discussing the genetics of the kids and the doe mob. Further hiking brought us to the doe mob; they were attacking larger diameter vegetation – oblivious to the weather. It was at that point I realized the Kiko was a breed of goat in a class all of its own. We purchased four Kiko herdsires in 1990 that met our specific selection and performance criterion. Each buck had to be a twin from the top 1% of the kid crop, and have sturdy legs and feet. They had to exhibit a mild temperament, great depth of heart girth, spring of rib with body capacity, width across the withers and rump, length and width of back and loin, fullness of hindquarter, perfect bite and two firm testicles (two teats only) in a pear shaped scrotum (no split). The bucks were from a mob that had no hoof trimming, a de- creased rate of deworming and performance tested. Since our initial purchase of four live bucks, we have purchased semen from five un- related lines in New Zealand. The bucks were health tested in New Zealand before semen collection for export/import requirements. Then the semen was tested and had to pass another set of export/im- port specifications before entry into the United States. Selection decisions for replacement females from both mobs (Spanish meats and mixed Dairy breeds) were based upon environ- mental adaptation, pedigree and progeny data, breeding values and performance, carcass data analysis, heritability and repeatability of traits along with genetic prediction(s) and the use of the sire sum- maries. Heritability is the expression of a trait in a population that is influenced by breeding values and phenotypic values. Breeding value(s) is related to an individual’s value as a genetic parent and phenotypic value(s) is the measured level of performance for a spe- cific trait within an individual. The major maternal (doe) traits are fertility, milk production, body condition score maintenance effi- ciency, motherability, longevity and freedom from dystocia (kidding problems). Major paternal (buck) traits are rate and efficiency of gain, meat quality and carcass yield.


The production characteristic traits selected have to be carefully chosen based upon criteria for production management in meat goats. The criteria used by Goats Unlimited: 1) adaptability to climatic, en- vironmental and native vegetation conditions, 2) the reproductive efficiency of the individuals within the mob and the mob as a unit, 3) growth rate of offspring at weaning (at 3 months), 8 months and 15 months of age and 4) carcass merit – quality grade and yield.


Adaptability


In selecting for environmental adaptation, Goats Unlimited se- lected both females and males based, as closely as possible, on nat- ural selection. It is a hard criteria at times because it can have negative effects on the growth rate in the kids which eventually af- fects maturity, both on-set of puberty and weight gain throughout their productive life. Therefore, intensive rangeland (pastureland) and brush management is needed to be sure that the young growing animals are receiving quality protein and energy from the native vegetation. Selection for the desired traits (health, longevity, main- tain body condition score, build resilience/resistance to internal par- asitism) is encouraged by using diversified browsing/grazing
