Management techniques for induction and synchronization of estrus in prepuberal gilts in confinement

Creator:

Schiemann, Calvin Aloysius

Abstract:

At weights of 81.5-90.5 kg, 187 prepuberal crossbred gilts were subjected to specific environmental stimuli, for up to 17 days, to determine which stimuli or combinations of various ones would initiate onset of estrus in prepuberal gilts. The stimuli used were: movement to new building, mixing or non-mixing of gilts,...

The influence of selenium on selenoprotein W

Creator:

Yeh, Jan-ying

Abstract:

The objective of our study was to investigate the effect of selenium on selenoprotein W. Western blot analysis indicated that selenoprotein W is present in muscle, brain, testis and spleen of rat tissues. Tissue distribution of selenoprotein W was not altered in rats fed various selenium levels. Among muscle, brain,...

Abstract:

Eight purebred rams (four Suffolk and four Panama) previously selected as high and low on the basis of post-weaning performance feed test of 84 days were used each of three years. Each of the rams was mated to approximately 25 grade Panama ewes each year. One ram and 25 ewes...

Embryonic mortality in pubertal gilts

Creator:

Archibong, Anthony Effanga

Abstract:

An experiment was conducted to compare the reproductive performance and serum concentrations of progesterone and estrogen of mated first (n=18) and third (n=18) estrous gilts slaughtered in equal numbers on days 3, 15 and 30 postmating. Fertilization rate did not differ between mated first and third estrous gilts. Embryonic survival...

Crystallin proteolysis in lens during aging and cataract formation

Creator:

Ueda, Yoji

Abstract:

The major purpose of this research was to characterize partially degraded proteins appearing in the ocular lens during aging and cataract, and to identify the responsible proteolytic activities. This research is significant, because increased protein degradation is associated with lens opacification and cataract. Determining the sites where lens proteins become...

Implications of selenium status for various metabolic and performance parameters in beef cattle

Creator:

Drake, Daniel J.

Abstract:

Metabolic and performance parameters of beef calves were compared between Se supplemented (Se) and control (C) dam treatment groups from known Se deficient cattle. Four trials were conducted at three locations involving 50, 36, 25 and 39 experimental dam/calf pairs. Se supplementation was either two 30 gram oral boluses (90%...
