Journal of Political Economy, 1994 U.S. beef cattle stocks are among the most periodic economic time series. A theory of cattle cycles is constructed on the basis of breeding stock inventory decisions. The low fertility rate of cows and substantial lags and future feedback between fertility and consumption decisions cause the demographic structure of the herd to respond cyclically to ...

Abstract Extract The clinical condition of “Kopziekte” or “grass tetany” in cows was recognized in the Netherlands for many years before Sjollema (1928, 1932) and his colleague (Sjollema and Seekles, 1929) first reported its association with low serum magnesium values in distinction to the low calcium of “milk fever”.

Osteochondrosis is a poorly understood condition that affects many species, including cattle. Its incidence is not fully appreciated in the cattle industry for many reasons. Most of the reports show a male, purebred predilection, but this may simply be a result of the typical population for which medical attention is sought.

Insecticides for Control of the Cattle Tick and the Southern Cattle Tick on Cattle1
Journal of Economic Entomology, 1968Twenty-seven insecticides applied to artificially infested cattle as sprays and 3 applied as sprays and dips were evaluated for control of the cattle tick, Boophilus annulatus (Say), and the southern cattle tick, B. microplus (Canestrini). Effectiveness was determined by inhibition of production of viable eggs by female ticks that were adults or nymphs

A number of anthelmintics are available for the control of gastrointestinal nematodes in cattle. In North America, O. ostertagi, Cooperia spp., lung worm, and F. hepatica probably cause the greatest losses in production. The older anthelmintics are often deficient in their action against some of these parasites. Recently, the Paratect morantel tartrate

Publisher Summary This chapter presents a description of the chromosome number, color inheritance, inbreeding, and other genetic characterestics of cattle. Information about the genetics of cattle has been acquired largely by studying the data that could be found concerning the resemblances between relatives.

Publisher Summary This chapter provides an updated and comprehensive review on the main features of cattle schistosomiasis. The adult worms are obligate parasites of the blood vascular system of vertebrates. They live in the perivesical, nasal or mesenteric, and hepatic veins of the host where they feed on blood and produce nonoperculated eggs with a
