Comparative values of liver nicotinamide nucleotide coenzymes, endocrine glands, and their relationships with production traits of diallel crossed beef bulls

Creator:: Anwar-Afghan, Mohammad
Abstract:: This investigation for the first time reports information on the correlation of various forms and ratios of nicotinamide nucleotide coenzymes in the liver tissue and endocrine glands weight with various production traits. Fifty-five inbred and line cross beef bulls raised under standard management conditions and slaughtered at 1000 lbs. body...

Effect of certain blood enzymes and cellular constituents on growth in different genetic groups of sheep

Creator:: Hutto, Daniel C.
Abstract:: In the present study, five breeds of ewes and their lambs were utilized. The breeds used were: Border Cheviot, Dorset Horn, Columbia, Suffolk and Willamette. In all, 31 ewes and 42 lambs were involved. The blood constituents which were determined for the ewes and lambs were: acid and alkaline phosphatase,...

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...

Performance of three inbred lines of Herford cattle and their linecrosses

Creator:: Munji, Marcus Tebid
Abstract:: Three inbred and relatively unrelated lines of Hereford cattle (1. Lionheart, 2. Prince, and 3. David) developed at the Corvallis branch of the Oregon Agricultural Experiment Station as part of the W-1 project of the Western States were crossed annually from 1963 through 1965 inclusive. Data on 137 inbred and...

Selection applied, response of traits and combining abilities of inbred lines of beef cattle

Creator:: Hoornbeek, Frank K. (Frank Kent), 1928-
Abstract:: The investigations reported are based on two studies; the first is concerned with the selection practiced for performance in one inbred Angus and three inbred Hereford lines of cattle, the realized responses, levels of inbreeding and associated performance, and heritabilities of the performance traits. Selection differentials for all performance traits...

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...

Effects of radiation on selection progress in mice

Creator:: Womack, James Ernest
Abstract:: The effects of x-irradiation on quantitative genetic traits was investigated by comparing the response of irradiated mice to selection for litter size and 28-day weight with the response to selection for the same two traits in non-irradiated lines. Irradiated lines were maintained at three levels of x-irradiation, 25 r, 50...

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...
