Gray partnered with the breeding managers of California Chrome, the 2014 winner of the Kentucky Derby and the Preakness, to sire a foal with a mare selected by Truthers (and others) who paid a hundred dollars for the privilege.
Indeed, during the first phase of the captive breeding, managers devoted attention to improve rearing and breeding conditions by limiting stress, improving success of semen collection, enhancing quality of artificial insemination of females, reducing hatching failure of artificially incubated eggs and increasing offspring survival and breeders well-being in captivity.
As mortality appears mediated by investment in reproduction and outbreaks typically occur on the breeding grounds, managers may consider encouraging subsets of females to abandon nesting attempts.
To minimize the deleterious effects of inbreeding, especially in the small effective population sizes of zoo populations, managers of captive breeding programs preferentially breed individuals with the fewest close kin in the population.
Breeding management needs consideration.
It is also hard to gainsay the authors' mantra about the dynamics of airports and growing cities: the airport leaves the city, the city follows the airport, the airport becomes a city, breeding regiments of middle managers with expertise in "revenue evaporation" and "fulfilment operations".
Accordingly, it is not uncommon for trainers of performance stallions or managers of breeding stallions to punish SEAM in an attempt to eliminate the behavior.
Managers of the breeding facilities suggested that the size of cage (2 sections or 3 sections) affected survival, with higher survival in clutches raised in large (3-section) cages.
Late last summer, when Juddmonte Farms' manager, Garrett O'Rourke, delivered the breeding operation's 2-year-olds to the trainer Bobby Frankel, he told Frankel that the dark brown son of A. P. Indy was his Kentucky Derby horse.
In this way hatchery managers can best develop breeding lines for specific systems and these lines can have stable effects over many generations.
