Dietary factors influencing enteric disorders of rabbits

Creator:: Grobner, Mark A.
Abstract:: An extensive literature review into the causes and controls of diarrhea was followed by three weanling rabbit performance trials to examine the influence of dietary modifications on diarrhea in the rabbit. In the first set of experiments, the ion exchangers clinoptilolite (0, 1.5 and 3.0%) and sodium bentonite (0 and...

Effect of dietary crude protein level and source of supplemental protein on performance of commercial rabbits

Creator:: Sanchez, William K.
Abstract:: A study was conducted to determine the effect of dietary protein on performance of commercial New Zealand White rabbits. In Part I of this study, three levels of crude protein (17.5, 19 and 20.5%) were fed to lactating does and their offspring during a 12 month period. Total rabbits born...

Mutagenic and toxicologic implications of pyrrolizidine (Senecio) alkaloids

Creator:: White, Randy Dee
Abstract:: The Salmonella/mammalian-microsome mutagenicity test was used to evaluate Senecio jacobaea (SJ) plant, Pyrrolizidine alkaloids (PA) and metabolites in goat milk, to evaluate response differences with microsomes from several animal species and to compare SJ plant responses to other plants. Bioassessment experiments were conducted to evaluate PA toxicity changes associated with...

Influence of dietary factors on tansy ragwort toxicosis in rats and horses

Creator:: Garrett, Betsy Jayne
Abstract:: Several experiments were conducted to investigate the effect of dietary factors such as amino acids, B vitamins, butylated hydroxyanisole (BHA) and phenobarbital on pyrrolizidine alkaloid toxicosis in rats and horses. The influence of St. John's wort, bracken, comfrey, and alfalfa on tansy ragwort toxicity was also examined. Effects of dietary...

Forage utilization by rabbits

Creator:: Harris, David Joseph
Abstract:: Several experiments were conducted to evaluate various forages and forage levels for use in rabbit diets. Several tropical forages were evaluated for their potential in feeding rabbits. One of the tropical forages, Desmodium distortum produced better growth performance than alfalfa meal. The tropical forages were used to derive prediction equations...

Senecio jacobaea : toxicity and effects on mineral metabolism in animals

Creator:: Swick, Robert Alphonso
Abstract:: Several experiments were conducted to examine the toxicity of Senecio jacobaea (SJ) in animals resistant to pyrrolizidine alkaloid (PA) intoxication and to determine the extent of alterations in mineral metabolism as a result of SJ intoxication. Inclusion of SJ into diets containing added copper (Cu) resulted in increased (P<.01) liver...

Evaluation of meadowfoam (Limnanthes alba) meal as a feedstuff for rabbits, poultry and sheep

Creator:: Throckmorton, John C.
Abstract:: Meadowfoam (Limnanthes alba) is a winter annual oilseed crop native to the Pacific Coast states. Seven experiments were conducted to evaluate extracted meadowfoam meal (MFM) as a feedstuff for poultry, rabbits and sheep. Three experiments were conducted to evaluate MFM as a protein supplement for broiler chicks and weanling rabbits....
