Effect of early exposure of tansy ragwort (Senecio jacobaea) on future grazing preferences of sheep

Creator:: Naranjo R., Victor Hugo
Abstract:: Tansy ragwort (Senecio iacobea) is a widely distributed weed in the Pacific Northwest (U.S.A.) where it causes severe damage to the livestock industry. Sheep are highly resistant to toxic effects of ragwort, therefore, induction of ragwort preference in sheep was sought as a means to control this poisonous plant. The...

Interrelationships of magnesium, potassium, and nitrogen in hypomagnesemia

Creator:: Alpan, Suleyman Orhan
Abstract:: The objective of this study was to investigate the influence of dietary magnesium, potassium and nitrogen on hypomagnesemia. Rats and dairy cattle were used as experimental animals. In the rat experiments, 270 albino rats, Mus norvegicus albinus, were used on 27 synthetic diets consisting of three levels each of casein...

Porcine zona pellucida immunocontraceptive vaccine for horses

Creator:: Bartell, Jennifer Ann
Abstract:: The Bureau of Land Management (BLM) maintains a growing number of feral horses on public rangelands. With population growth rates as high as 22% annually, herds are exceeding their carrying capacity and millions of dollars are spent maintaining captured horses in holding facilities awaiting adoption. To manage the feral horse...

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...

Flow cytometric evaluation of spermatozoan nuclear chromatin structure and viability

Creator:: Ballachey, Brenda Elizabeth
Abstract:: I. Frozen bovine semen samples were measured by flow cytometry (FCM) to determine if FCM analyses could be useful for sperm quality evaluation and prediction of bull fertility. Fluorescent dyes utilized were acridine orange, to measure sperm nuclear chromatin heterogeneity by quantifying susceptibility of the chromatin to denaturation, and rhodamine...

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,...

The effects of differing hazelnut concentrations in hog finishing rations with respect to pork shelf-life and fatty acid composition

Creator:: Parker, Nathan B.
Abstract:: Commercial hog diets in the United States commonly contain lipid sources high in polyunsaturated fatty acids, most notably linoleic acid (18:2). This may result in greater deposits of linoleic acid in pork adipose tissue, contributing to an increased potential for lipid oxidation, high n-6/n-3 fatty acid ratio and increased fat...

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...
