A Morphological Study Of Some Larval Ticks Of The Genus Dermacentor With Emphasis On Structures Of Possible Taxonomic Importance, Richard Grant Robertson
A Morphological Study Of Some Larval Ticks Of The Genus Dermacentor With Emphasis On Structures Of Possible Taxonomic Importance, Richard Grant Robertson
Theses and Dissertations
This study was undertaken to evaluate and determine morphological characteristics which might prove valuable in the identification of the larvae of the following species of ticks of the genus Dermacentor Koch: D. albipictus Packard, D. andersoni Stiles, D. hunteri Bishop, D. parumapertus Neuman, and D. variabilis Say. A taxonomic key for the identification of all of the Canadian and United States species of the larvae of the genus Dermacentor Koch cannot be constructed until specimens of D. halli and D. occidentalis have been examined. However, the followng conclusions were reached regarding the species studied: 1. Position of setae is of …

A Histological Study Of The Postnatal Development Of The Bovine Testis, R. G. Fossland, A. B. Schultze
A Histological Study Of The Postnatal Development Of The Bovine Testis, R. G. Fossland, A. B. Schultze
Nebraska Agricultural Experiment Station: Historical Research Bulletins
A limited number of detailed studies on the development of the bovine testis from birth to sexual maturity have been reported. Further study of bovine testis development appears desirable to furnish additional observations and to note variations that may occur during the developmental process. Information on the process of spermatogenesis should furnish a basis for experimental work designed to promote increased spermatogenic activity in the postpubertal testis as well as for work directed toward promoting complete spermatogenesis at an earlier than usual age. This report is a study of the histological picture of the testes from 56 bulls varying from …
The Life Cycle And Pathogenicity Of Eimeria Auburnensis, Wayne Norris Clark
The Life Cycle And Pathogenicity Of Eimeria Auburnensis, Wayne Norris Clark
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Coccidiosis in cattle is caused by microscopic one-celled sporozoa belonging to the order Coccidia and the genus Eimeria. Coccidiosis is a common disease of young calves that weakens or kills them, but the disease also occurs in older animals. Eleven species have been reported in cattle of the U.S.A.(Davis and Bowman, 1956). Of this number only two species, Eimeria bovis(Hammond et al., 1946) and Eimeria zurnii(Davis and Bowman, 1957) have been proven pathogenic for cattle, but except for Eimeria alabamensis(Davis et al., 1955) no experimental work has been done on other species.

Bovine coccidiosis is a serious threat to the economy of the cattle industry in the United States. In 1954 the United States Department of Agriculture reported that over $10,000,000 was lost annually as a result of mortality and morbidity in cattle due to this parasite (1). These losses alone amounted to more than one fourth of the total loss in cattle due to parasitism.

Observations Of Pituitary Hormone Injections And Ripening Of Fish, D. K. Kaushik
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A dependable source of quality fish spawn is a fundamental prerequisite for fish culture development. This is especially important inasmuch as most of the cultivable species do not breed in confined waters. Also, sport fisheries are gaining greater popularity, and subsequently the fish supply is being taxed. Still another need for fish spawn is in the ever increasing demand for bait minnows. Also, the construction of more and more dams has resulted in insurmountable obstacles for ascending and descending fish, which may ultimately result in complete destruction of some fisheries. Thus some measure of artificial propagation will have to be …
