Applied Genetics and Genomics in Alfalfa Breeding
Alfalfa (Medicago sativa L.), a perennial and outcrossing species, is a widely planted forage legume for hay, pasture and silage throughout the world. Currently, alfalfa breeding relies on recurrent phenotypic selection, but alternatives incorporating molecular marker assisted breeding could enhance genetic gain per unit time and per unit cost, and accelerate alfalfa improvement. Many major qua...
متن کاملMethods of Embryo Sexing in Cattle Breeding: A Review
Different livestock sectors as beef industries get benefit from the production of male animals while dairy industries get benefit from the milk production by the female animals. Therefore, it is obvious need to produce the animals of desired sex which can be achieved by predetermining the sex of conceptus at the time of conception i.e. pre determination of sex may be of great economic importanc...
متن کاملBreeding and Genetics III: Methods
Concerns have been raised in the past about the Dairy Herd Improvement Association recording frequency, because the interval between samples, about 4 weeks, may not capture the peak production for cows with shorter lactation (less than 10 mo), which have led to the conclusion that these cows have an atypical lactation curve shape. This may be due to sampling frequency rather than biological dif...
