The objective of this research was to determine effects of a single injection of the PG synthesis inhibitor flunixin meglumine (FM; 1.1 mg/kg of BW, intramuscularly) approximately 13 d (range 10 to 15 d) after AI on pregnancy establishment. Three exp

Objectives of these studies were to determine the effects of flunixin meglumine (FM) administration on early embryonic mortality and circulating PG and cortisol concentrations in transported and non-transported cows. Cows (n = 483) from 3 locations w

We evaluated whether a fixed-time AI (TAI) protocol could yield pregnancy rates similar to a protocol requiring detection of estrus, or detection of estrus and AI plus a clean-up TAI for heifers not detected in estrus, and whether adding an injection

The objective of this study was to evaluate synchronization and pregnancy rates of beef heifers supplemented with 0.91 kg of whole sunflower seeds for 0, 30, or 60 d before AI. Beef heifers from four locations (n = 1,014) were assigned by BW to treat

The objective of this study was to evaluate the effects of cubing alfalfa on heifer development and in situ ruminai NDF and CP disappearance. One hundred ninety-two prepuberal crossbred heifers were allotted to 16 pens with each pen randomly allotted

Two hundred ten spring-born English crossbred beef heifers were used in two experiments in consecutive years using a randomized complete block design. The objectives were to determine the effects of increasing dietary intake of ruminally undegradable
