Cytogenetics, Breeding Behavior And Tumor Formation In Progeny Of A Homozygous Triploid Sorgham, Peck Sun Lin Jan 1966

Cytogenetics, Breeding Behavior And Tumor Formation In Progeny Of A Homozygous Triploid Sorgham, Peck Sun Lin

Electronic Theses and Dissertations

Univalents were studied in the microsporocytes of a triploid sorghum plant which was derived from a selfed haploid. At metaphase I, the frequencies of univalent varied with cell maturity which was judged by anther development. The developmental stages of anthers were E, M, L, VL, and VVL for early, medium, late, very late, and very, very late respectively. Univalents averaged 2.3 per cell at the earliest (E) stage increased to 3.9 per cell at the latest (VVL) stage. A similar tendency was found from L to VVL at anaphase I and telophase I. Trivalents were also studied in cell populations …

Lipid And Amino Acid Studies Of Selenium Toxicity With The Rat, Mary Jane Abraham Jan 1966

Lipid And Amino Acid Studies Of Selenium Toxicity With The Rat, Mary Jane Abraham

Electronic Theses and Dissertations

Selenium exhibits unusual biological properties in that it is a micro nutrient for animals (1) and some plants (2) and yet at slightly higher levels it may be very toxic (3,4). Neither the active forms of selenium nor the mechanisms by which its biological effects are produced are well understood. Thus, many aspects remain to the investigated in this area. Franke (9), while working with the affected grain at South Dakota State College, produced the toxic symptoms experimentally. Following the discovery by Robinson (10) of selenium in toxic forages and grains. Franke (12) further deduced that plants incorporate soil selenium …

The Effect Of Methods Of Storage On The Gross Energy, Chemical Composition And Feeding Value Of Alfalfa, Guru Prasad Mohanty

Electronic Theses and Dissertations

Production of good quality hay or silage and its proper storage without loss of the nutritive value is an important problem for dairy farmers. They are particularly interested in meeting the energy needs in feeding their herds for milk production. During the past decade there has been a substantial increase in the volume and intensity of research towards the nutritional and calorimetric aspects of cattle feeds. A number of unavoidable problems come in the way of their application causing financial disaster in today’s competitive economy of dairy farming. To increase milk production or to maintain a high level of production, …

Diseases Of Baby Pigs, Norman R. Underdahl Nov 1965

Diseases Of Baby Pigs, Norman R. Underdahl

South Dakota Swine Field Day Proceedings and Research Reports, 1965

The diseases which affect baby pigs are the same as those which also affect older swine . However, when baby pigs are affected the disease is frequently much more severe. The baby pig does not have the reserve to withstand a prolonged infection and is dependent on the continuous supply of milk for energy. When this milk supply is lost by vomition or when the pig refuses to eat , then the disease rapidly gains control. Other organ isms which are usually non-infective also be gin to multiply and be cause of the weakened condition brought about by the disease …

Structural Relationships For National And Regional Beef Cattle Production, John E. Trierweiler, Donald B. Erickson Jun 1965

Structural Relationships For National And Regional Beef Cattle Production, John E. Trierweiler, Donald B. Erickson

Agricultural Experiment Station Technical Bulletins (1939-2011)

Changes have occurred in recent years which have produced changes in the beef industry. Structural relationships that existed for the producer-feeder are not necessarily important in the operation of the cow-calf operator or the feed-lot operator. Because of these changes, a more thorough knowledge of the supply response of a small regional breakdown of the beef cattle industry should be available to farmers, econmists, outlook workers and policy makers in the agricultural industry. The study examines cow-calf operations and feed-lot operations to investigate U.S. beef calf production and develop an economic model for number of beef calves produced by region …

The Alfalfa Weevil And It's Control, Cooperative Extension South Dakota State University Apr 1965

The Alfalfa Weevil And It's Control, Cooperative Extension South Dakota State University

SDSU Extension Fact Sheets

The alfalfa weevil was first detected in South Dakota in Fall River County in 1936 and was found in Custer County in 1937. The insect has been collected in 18 western South Dakota counties. Damaging populations of this insect now exist in a five-county area (figure 1). Damaging populations will probably start appearing in other counties as the weevil populations increase in future years.

Suitability Of Cheese Whey As A Substrate For Vitamin B12 Production By Propionibacterium Shermanii, Lloyd B. Bullerman Jan 1965

Suitability Of Cheese Whey As A Substrate For Vitamin B12 Production By Propionibacterium Shermanii, Lloyd B. Bullerman

Electronic Theses and Dissertations

Disposal of waste is a major problem confronting the food industry today. These wastes are of varied composition and origin. One such material is cheese whey. Most of the surplus whey is considered to be and handled as an industrial waste, and disposed of in some manner. Whey is a by-product of cheese making. Since 90% of the starting volume of milk remains as whey after cheese manufacture, annual production of whey is large. Herein lies a large part of the whey problem, the fact that the actual consumption of whey is a small part of the total production. If …

Comparisons Of Ear Corn And Shelled Corn In Various Types Of Rations For Finishing Cattle, Gary Bruce Haiwick Jan 1965

Comparisons Of Ear Corn And Shelled Corn In Various Types Of Rations For Finishing Cattle, Gary Bruce Haiwick

Electronic Theses and Dissertations

Ruminants were once considered placid animals with the rumen serving as a storehouse for the feeds harvested when favorable weather and freedom from predatory animals permitted, and then retiring to a relatively safe place to ruminate and digest the stored feed. The large capacity and microbial digestion within the rumen enable ruminants to consume and utilize roughages efficiently. A large number of experiments have been conducted during the past several years to determine the effects of proportion of concentrates to roughages on rate and efficiency of production by cattle. Alfalfa hay is widely used in finishing rations for cattle and …

Effects Of B Vitamin Deficiencies On Energy Metabolism Of The Chick, William Clarence Lockhart Jan 1965

Effects Of B Vitamin Deficiencies On Energy Metabolism Of The Chick, William Clarence Lockhart

Electronic Theses and Dissertations

Approximately two decades ago Robertson et al. (1948) reported that high-energy diets supported faster growth of young chicks with an improvement in feeding efficiency. This seemed to open an era in poultry nutrition in which much work was conducted in order to establish the quantitative relationships between dietary energy levels and nutrients. With current emphasis on the energy content of the diet, a knowledge of those factors which interfere with the most efficient utilization of energy is important. Nutritional imbalance was shown by Sure (1941) to decrease the net energy or productive energy content of the diet. The B complex …
