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...

The effects of aerobic and anaerobic fermentation on the nutritive value of ryegrass straw

Creator:: Jones, Steven Ryan
Abstract:: A series of in vitro laboratory trials and in vivo sheep digestion trials were used to evaluate aerobically or anaerobically fermented perennial ryegrass straw. The laboratory trials consisted of a silage study, where mini-silos were used in a 9 X 2 factorial design with nine levels of whey (0 to...

In vitro and in vivo evaluations of chemically treated ryegrass straw

Creator:: Anderson, Daniel Craig
Abstract:: Seven in vitro trials were conducted to compare the effects of soaking annual ryegrass straw in solutions of sodium hydroxide (Na₄OH), potassium hydroxide (KOH), ammonium hydroxide (NH₄OH), or sodium formate (NaCHO₂) at varying levels. Dry matter digestibility (DDM) was the criterion used to measure treatment response. A 3 x 3...

The effect of various additives on nutritive value of ryegrass straw silage

Creator:: Shultz, Thomas Anthony
Abstract:: Observations were made on silage pH, chemical composition and 24hr in vitro dry matter digestion (IVDMD) to evaluate effects of various additives ensiled with annual ryegrass straw. Additives were compared in factorial designed trials utilizing .95 1 glass jar silos. Selection of additives used in each subsequent trial was based...

Ruminant and microbial physio-chemical response to abrupt ration changes as influenced by chemical and/or biological means

Creator:: Patton, Westley R.
Abstract:: Three trials with wethers and four trials with steers were conducted to determine some of the effects of sodium bicarbonate, calcium hydroxide and/or transfer of ruminal contents on ruminant adjustment to abrupt changes to concentrate rations. Lambs fed a basal concentrate diet plus sodium bicarbonate had the highest average feed...

The role of costimulation and adjuvants in the development of T cell effector and memory responses

Creator:: Maxwell, Joseph R.
Abstract:: T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...

A morphological, physiological and gentic investigation of the African pygmy goat

Creator:: Blanks, George Anthony
Abstract:: Six groups of goats were used in the study. These were the normal group (Saanen, French Alpine, and Nubian breeds), 1/4 pygmy group (first backcross to normal), 1/2 pygmy group (F1) 3/4 pygmy group (first backcross to pygmy), 7/8 pygmy group (second backcross to pygmy), and pygmy group0 The mean...
