Question

11.6 A ewe's d rect and maternal EPDs for weaning weight (a trait of the lamb) are: EPDd1 lb EPD+2.5 lb a. Given just these EPDs, what do we expect her future lambs to weigh (ex- pressed as a deviation from the population mean)? b. Th e ewe's permanent environmental effect (Ep) is predicted to be +3 lb. What is her MPPA? C. Estimates of contemporary group effects ( НЕсд) for her flock average 39 lb. What do we expect her future lambs to weigh?

Answer 1

a)

EPD, they have provided the indication of genetic mothering ability.

The maternal milk EPD that have expressed in the pound of lamb weaned but do not the pound of milk production .

Selection to the maximum maternal milk EPD to the participated have improved milk production and also mothering ability in the flock.

The calculation of the milk plus growth EPD. sum of the maternal milk EPD plus half of wearing weight EPD.

That sum has determined the genetic contribution of a ewe to the wearing weight of the lambs.

b)

This question has the study that earning weight from calve was used to estimate genetic and environmental variance.

That model has to tack much correlation between permanent effect to the dams and daughter.

The estimate residual and direct genetic variance to the similar for the total values of lambda.

There result indicated the relationship between maternal permanent environment effect and the daughter weaning effect.

The MPPA have an important role in the ewe permanent environment effect to determine the pound +3.

c)

In the contemporary group, an eject has increased the body weight of the lamb.

The lamb has to leave together in the group that influence the body weight by the action of the behavioural change and also have effected the feeding behaviour.

That have one idea to remark the lambs and its production, that domestic lambs to grown from the 100 pounds to the 110 and 120 after some time later.

I have always figured, that selfish approach to viewing the end product, at about 70-80 pound of the lambs have combined to its bone, meat and its fat ratio also counted.
