Genotype x environment interactions in sheep

Creator:: Corum, Kathleen Steele
Abstract:: The 865 ewe production records taken from three lamb crops, were analyzed to study breed effects, heterosis, environmental effects and interactions between them, and breed and heterosis x environment interaction effects on ewe production traits. In each of two environments, approximately 144 ewes were mated in a three breed reciprocal...

Breed and heterosis effects on wool and lamb production of rotationally crossed ewes

Creator:: Gallivan, Catherine Agnes
Abstract:: One thousand twenty-three lambing records of 351 ewes bred in a rotational crossbreeding system involving Columbia or Targhee, Hampshire and Finnish Landrace breeds were examined. A regression approach was used to determine the effects of breeds and heterosis on wool grade, greasy fleece weight, ewe weight at lambing, lambing date,...

Genetic and environmental differences in age at first estrus and in wool and lamb production of crossbred ewe lambs

Creator:: Cedillo, Rose Mary
Abstract:: Genetic and environmental factors affecting age of first estrus, wool production, reproduction and lamb production were examined in eight groups of crossbred ewe lambs from two birth years. The 399 ewe lambs whose first year production was analyzed were from eight crossbred groups resulting from mating North Country Cheviot, Dorset,...

Perinatal mortality and preweaning growth of progeny of ewe lambs

Creator:: Gendron, Eric
Abstract:: Half Polypay ewe lambs were bred to Suffolk, North Country Cheviot and Hampshire rams to lamb at about one year of age. Type of birth-rearing significantly affected mortality by 70 days of age and all weights of lambs from birth to weaning. The mortality rate at 70 days of age...

Breeding bird community composition in relation to riparian vegetation structure in grazed habitats

Creator:: Sanders, Todd Alan
Abstract:: Riparian zones provide habitat for breeding birds in the semiarid western United States; however, there are few data available that address the effects of livestock grazing strategies on riparian habitats and avian communities. Documenting avian community composition in different riparian vegetation communities and relating vegetation communities to livestock grazing strategies...
