Genetic and physiological factors associated with gonadotropic and thyrotropic hormone content of sheep pituitaries

Creator:: Plotka, Edward Dennis
Abstract:: Data were taken from 47 animals consisting of five breeds: Border Cheviot, Columbia, Dorset Horn, Suffolk, and Willamette. Both sexes were represented in each breed, although in unequal numbers. The pituitaries were assayed for gonadotropic and thyrotropic hormone content by injecting a suspension of the macerated gland in saline into...

Response of scorbutic guinea pigs to ascorbic acid and adrenocorticotropic hormone (ACTH)

Creator:: Riker, Joseph Thaddeus III
Abstract:: Thirty-six female guinea pigs were placed on a scorbutogenic diet for 14 days and then divided into groups of four. Three groups received adrenocorticotropic hormone (ACTH) with each group given 10, 20, or 40 units. Three groups each received 50 mg of ascorbic acid and three groups received 50 mg...

Relationship of certain blood nitrogen constituents with growth in different genetic groups of sheep

Creator:: Yodseranee, Somchit
Abstract:: Market lamb production usually requires a short period of time. The success of production is therefore dependent upon the growth rate of the lambs which is influenced by milk yields of the ewes. Different growth potentials of animals result from a difference in their utilisation of food. Since metabolism affects...

Certain genetic and maternal environmental influences on growth rate and body composition of lambs

Creator:: Addleman, Albert Duane
Abstract:: The present study was designed to investigate the relationship of milk production and milk quality to growth rate and certain organ-oleptic measurements of lambs of mutton breeds, Nine mature ewes in their fourth lactation of the Border Cheviot, Dorset Horn, Columbia, Suffolk, and Willamette breeds were acquired making a total...

Certain physiological and pharmacological effects of radiation on rabbits

Creator:: Wagelie, Edwin Gan
Abstract:: Data were taken, following irradiation exposure to 100r and 300r cumulative dose, on 89 rabbits of three breeds that vary greatly in body size. Hematological, intestinal motility, and ear vascularity examinations were performed. Least square estimates have been obtained and an analysis of variance has been conducted in order estimate...

Ova tranfers in sheep and rabbits : studies on material influences and irradiation damage

Creator:: Hunt, William Lynn
Abstract:: The first study utilized ova transfer in sheep and involved hormonal treatments for synchronization of estrus and superovulation in an investigation of crossbred maternal influences on inbred and linecross lambs. Synchronization of estrus in ewes was achieved effectively with either oral progestogen, 6 α-methyl-17α-hydroxy-progesterone acetate (60 mg./ewe/day), or intramuscular injections...
