Characterization Of Biological Types Of Cattle Iii. Carcass Composition, Quality And Palatability, R. M. Koch, M. E. Dikeman, D. M. Allen, M. May, J. D. Crouse, D. R. Campion

Department of Animal Science: Faculty Publications

Composition and quality characteristics of 1,121 steer carcasses obtained after mating Hereford and Angus cows to Hereford, Angus, Jersey, South Devon, Limousin, Charolais and Simmental sires were compared at a (1) constant age, (2) constant weight, and (3) constant percentage of fat in the longissimus muscle. Taste panel evaluation was made on a subsample of 496 carcasses. Growth rate of retail product, fat trim and bone differed significantly among sire breed groups. Breed group differences in relative proportions of retail product, fat trim and bone were largest when compared at a constant carcass weight and smallest when compared at equal …

Food Interactions Between Utah Prairie Dogs And Cattle, Dennis Crocker-Bedford

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the food interactions between Utah prairie dogs (Cynomys parvidens, Allen) and cattle (Bos taurus). During 1974 and 1975, three prairie dog colonies near Panguitch, Utah, were studied intensely: "Oldfield" was chosen to represent colonies near fields of alfalfa (Medicago sativa); "Lowercrested" was chosen to represent colonies below 2,200 meters above sea level (a.s.l.) which were not near alfalfa, and "Uppercrested" was chosen to represent colonies above 2,200 meters a.s.l. which have been planted with crested wheatgrass.

Visual observations were made of Utah prairie dogs to determine their diets. Livetrapping of prairie …

Cattle Fertility Not Harmed By Pour-On Insecticides, D J. Barker

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

Pour-on insecticides have been a feature of lice and fly control on cattle for many years and in many countries, but it seems that only in Western Australia have they been suspected of lowering fertility.

Frequent reports of this effect have been received by the Department of Agriculture since the first pour-on insecticide was marketed in W.A. in the late 1960's, culminating in the research work reported below.

The work clears pour-ons as a cause of reduced fertility in herds.
