Potentiation of acute carbon tetrachloride hepatotoxicity by dietary exposure to chlorophenothane (DDT) in rats

Creator:: Koeferl, Michael Tallyn
Abstract:: There has been no toxicologic proof that the long-term, low-level exposure of man to chlorophenothane (DDT) is linked with an increased susceptibility to toxicity or disease. Acute pretreatment of rats with 75-100 mg/kg DDT has been demonstrated to potentiate CCI₄-induced hepatotoxicity in that species (McLean and McLean, 1966). Since the...

Physiological and nutritional interrelationships of mineral elements to growth and reproduction in turkeys

Creator:: Egwuatu, Charles Obiajulu
Abstract:: Experiments involving poults were conducted with the primary objective of studying the effects of sodium chloride on field rickets. A second objective was to study the effects of mineral elements on reproduction of turkey breeder males and females. Three experiments were conducted with poults. A comparison of added dietary sodium...

A comparison of in vivo and in vitro techniques for the evaluation of varying roughage-concentrate rations

Creator:: Klett, Ramon Hollis
Abstract:: The objective of this study was to compare the total collection (in vivo), nylon bag, and in vitro digestibility techniques under standardized conditions. Twin steers were used simultaneously to measure the digestibility of five rations consisting of the following ratios of alfalfa hay to steamed roller barley: 4:0 (I), 3:1...

Estimation of general and specific combining abilities from a diallel cross of three inbred lines of Suffolk sheep

Creator:: Schilling, Prentiss E. (Prentiss Edwin), 1941-
Abstract:: The investigations were based on a complete diallel cross among three inbred lines of Suffolk sheep. Line of sire effects were assumed to be an estimate of general combining ability effects while sire x dam interaction was assumed to be an estimate of specific combining ability. The line of dam...

Electrocardiograms and related variables of dwarf beef cattle

Creator:: Pinjani, Moti, 1939-
Abstract:: Electrocardiograms from 12 compressed male (CM), 16 compressed female (CF), ten synthetic compressed female (SCF), nine brachycephalic female (BF), and 15 dolichocephalic female (DF) dwarfs from Davis, California, taken in the scapular lead S-II (prescapular position positive and right forelimb negative) were analyzed, The data on dwarf electrocardiograms were compared...

Vitamin E, selenium and tri-o-cresylphosphate interrelationships

Creator:: Shull, Lee R.
Abstract:: A two-part study was conducted to investigate some of the nutritional relationships between dietary tri-o-cresylphosphate (TOCP), a toxic stress material, and dietary vitamin E and selenium. In part one, growth rate of male weanling Long-Evans rats and day-old Japanese quail (Coturnix coturnix japonica) was used to determine the protective action...

A study of chronic Senecio jacobaea toxicosis in calves and ponies

Creator:: Pearson, Erwin G.
Abstract:: An experiment was designed to simulate field conditions of tansy ragwort poisoning in cattle and horses. Four calves and four ponies were fed pelleted feed containing 5% Senecio jacobaea and two ponies and two calves were used as controls. The feeding continued for two months. Following this, the chronic delayed...

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...

Estimates of combining abilities, heterotic effects and phenotypic correlations among in-bred lines of beef cattle and their line-crosses

Creator:: Humes, Paul Edwin
Abstract:: The investigations were based on a complete diallel cross among three inbred lines of Hereford cattle. Records of Angus calves born during the same period were used to obtain more accurate estimates of environmental effects and to determine breed differences among the various traits included in the study. Estimates of...
