This study involved the use of the two-choice preference test,
where the choices were tap water and tap water-chemical solutions,
to determine the responses of sheep to ascending concentrations of
20 chemicals (taste stimulants). The chemicals tested were: the
sugars, sucrose, maltose, lactose, glucose, fructose and galactose;
the sodium salts...
The objective of the thesis was to determine the effects of
isolated coumestrol on the growth, carcass characteristics and
certain organs of wether lambs. The first of two trials was conducted
over an eight week period with two groups of heavy wether
lambs. Trial two was conducted over an 11...
Maternally-derived transcripts and proteins support early bovine and ovine embryo development until the 8- to 16-cell stage, at which time embryonic transcripts become essential for continued development. One purported mechanism for the switch from maternal to zygotic control of development (maternal to zygotic genome activation; MZGA) is the appearance of...
Embryonic loss of potential lambs resulting in partial failure of multiple ovulations is a significant factor in the reproductive rate of prolific breeds. The roles of genetic and nutritional variation (and their possible interaction) on embryonic loss were studied by mating blackface and whiteface ewes of either high or low...
