Explanation:
A farmer wants to produce a sheep with finer wool. How could he do this by selective breeding?
If he wants to produce the finest wool he will raise goats but they make mostly lower value hair and less that pound of the fine wool that is so prized. It would take a good deal of research and possibly 10’s of years of experiments to tell if there was more potential to improve the goats than there is sheep. The first thing to do would be to find the rams you want and sequence there genome and she which one is more diverse. The more diverse the genome the more room to improve the breed without bring in outside genetics.
Once he decides on a breed he needs to see if there is market for what he wants to breed and develop index for both the ewes and bucks. Wool diameter and fleece wight would have the most weight in the index. Reproductive performance, soundness of feet and legs and any detrimental repressive gene would cull the sheep. Some value should be given to the dollar value of lambs as the swing on the abattoirs hook or the grocers meat case. A long breeding life has value.
Each breeder has to build their own index to match the flock that have with the flock they want to have 20 years from now. He can’t just breed for fine wool or in a few years he will have a bunch of crippled sheep that have lambs that are too small to sell by Ester and take an awful dock in price later in the spring.
Then they need to develop a plan to reach their goals. Financing is the biggest issue. The returns to management and capital are small and make take generations to fully be realized in a world that does’t value wool or other natural fiber very much.
It is possible to start small and grow larger by buying proven ewes being culled by breeder and herdsmen due to age and broken mouths and putting them on better pastures and feeding them supplemental rations to get few more lambs from them. You will have ewes die with this program but I have seen excellent registered cattle herds built on school teachers salaries.
For fastest progress you need to breed he ewes by artificial insemination. “” gives good overall view of the process what I can’t find is if the Merino breed association position on artificial insemination and stud ownership. Most registered breed associations require partial ownership in rams that father registered lambs. If he wants to sell rams for stud to other Merino breeders as it will probably be the majority of his income by turning many of his $240.00 dollar wethers into $900.00 to $2,500.00 rams.
The hard part is doing it. The day to day care of the sheep, finding and buying the the best genetics and striking a ball ace in selecting for the desired traits while maintaining the soundness and breed defining traits. He must also keep the inbreeding levels at a point his customers are comfortable with. Beware the specter of Prince Domino a Hereford bull at his peak on the average he was thought to be he grand father of all registered Hereford cattle. There were isolated herds that had an inbreeding coefficient to Prince Domino over 0.5 the relationship of brothers. We later found Prince Domino was the source of Snorter Dwarfism
Should he find a stud he likes very well it would probably be worth the cost of sequencing his genome to rule out or identify and serious regressive genes he might carry.
This should start him on quest. He needs to lean how to learn on his own for he will be doing it the rest of his life.
If you don't mind
I will tell the truth:
Work hard you will get good result but I am not telling it is worst it is good. But I am telling you to make hard you will get it.
