Genetic parameters of the house fly (Musca domestica Linn.)

Creator:: Konanta, Sugsanguan
Abstract:: Eight strains of housefly, Musca domestica Linn., from two laboratories were intercrossed to form a stock population. Virgin males and females from the stock were collected, and nine sets, each consisting of twelve males mated to five females, were successively done. Pupae weight, adult weight, emergence time and egg production...

The comparison of two methods of evaluating inheritance of milk production of dairy sires

Creator:: Srinives, Supote
Abstract:: The production records used were all converted to a comparable based, 305 day lactation period, two times a day milking, and mature equivalent (305 days-2-x-ME) of 71 cows from four Holstein bulls and 59 cows from four Jersey bulls were used for the study. The Equal Parent Index, Regression Index...

An analysis of the response to selection for high and low rate of gain in the mouse, Mus musculus

Creator:: Burrill, Melinda Jane
Abstract:: An experiment was conducted to examine the responses to selection for high and low rate of gain in the mouse under a system whereby inbreeding was maximized. Rate of gain was measured by an index designed to include gains in both the pre- and postweaning periods with the gains in...

Association of genetically determined polymorphic blood components with prolificacies of purebred and crossbred pigs

Creator:: Kray, Roger LeRoy
Abstract:: Crossmatings were accomplished among three semi-closed lines within a population of pigs, for the purpose of investigating effects of crossbreeding on reproductive traits. Two of the lines were purebred (Berkshire and Yorkshire); the third line ("Composite") consisted of descendants from inter se matings among offspring of crosses of the Berkshire...

Gonadotropins in pituitaries of inbred and linecross beef bulls and effects of irradiation of mammalian pituitary glands on their ability to induce in vitro ovulation of frog ovaries

Creator:: North, Warren Arthur
Abstract:: There were two studies involved in the thesis research. In the first study, variation in the amount of adenohypophysis gonadotropins among 22 individual beef bulls were investigated. These bulls represented four inbred lines, and six linecrosses. The bulls were raised in the Oregon State University purebred herd. The bulls were...

Serum T₄ and liver NAD and NADP as performance indicators in beef cattle

Creator:: Brokaw, Bryan Edward
Abstract:: The relationships of serum T₄ (thyroxine) levels and liver nicotinamide nucleotide coenzyme (NAD and NADP) levels with production of traits of beef cattle were investigated at both weaning (182 kg) and following performance testing (363 kg). In addition, the value of these parameters as selection criteria for improved performance was...

Genetic polymorphism of sheep hemoglobin

Creator:: Templeton, Joe Wayne, 1941-
Abstract:: Five breeds of sheep (Columbia, Targhee, Rambouillet, Lincoln, and Suffolk) were found to possess two hemoglobin types (Hb. A and Hb. B) when their hemoglobins were examined by disc gel electrophoresis. The hemoglobin alleles proved to be co-dominant. Three of the breeds (Columbia, Targhee, and Rambouillet) were maintained at altitudes...
