Female traits, ovary and follicle characteristics, and the conditional probability of normal oocyte development after superovulation of beef cows
Article Abstract:
The influence of nutrition on the growth and maturation of bovine oocytes was investigated using a model incorporating the effect of nutritional level on progesterone levels, corpus luteum function and follicle size. Gonadotropin was administered to cows on different nutritional regimens afterwhich, oocytes were aspirated from their ovaries. These oocytes were characterized and their maturation, fertilization and development in vitro were evaluated. It was shown that nutritional levels significantly affected oocyte development.

The effect of postexsanguination infusion of beef on composition, tenderness, and functional properties
Article Abstract:
An experimental study was conducted to determine the effects of arterial infusion with maltose, dextrose, polyphosphate and glycerin on beef composition, tenderness and related functional properties, of dairy cows. Beef characteristics of experimental group cows infused with a solution of glycerin, maltose, dextrose and phosphate were compared with control group cows. Results indicated that infusion improves functional properties and tenderness of the carcass. Infusion, also, increased dressed carcass yield.

Effects of nitrogen fertilization and maturity of bromegrass on nitrogen and amino acid utilization by cows
Article Abstract:
The effects of nitrogen fertilization and maturity of bromegrass on nitrogen and amino acid utilization by cows was studied by feeding four nonlactating Holstein cows with bromegrass. The hay was fertilized with 89 kilograms of nitrogen per hectare and harvested in full-head stage of maturity. Results show that fertilization and maturity of bromegrass significantly affected nitrogen utilization.
