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 …

Relation Of Heart Girth To Weight In Holsteins And Jerseys, H. P. Davis, W. W. Swett, W. R. Harvey

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Body weight is the one measurement most extensively used to evaluate growth, condition, and value for beef, and as a basis for calculating feed requirements for cattle. Weight can be determined readily by scales but unfortunately scales of a capacity adequate for weighing cattle are not always available. Thus there is a real need for a basis of estimating weight from some body measurement that can be obtained easily and at a minimum of cost and time. It is the aim of this study to utilize additional data now available to increase further the accuracy and reliability of estimating weight …

Hay For The Dairy Herd : Quality Or Quantity?, F E. Ryan

Journal of the Department of Agriculture, Western Australia, Series 4

CONSERVATION of hay on dairy farms has increased in recent years but so far emphasis has been on quantity rather than quality and in some districts paddocks are closed up very early to increase yields per acre of hay.

Recent trials have shown that late closing of hay paddocks on dairy farms gives higher quality hay, more winter grazing and a better balanced pasture. The gain in quality more than compensates for any drop in yield.

Selecting A Herd Sire, R A. Bettenay

Journal of the Department of Agriculture, Western Australia, Series 4
