Disease relevance of MGA

• The released data contain honeybee expressed sequence tags (ESTs), re-examined and re-annotated complete genome data of Escherichia coli K-12 W3110, medaka WGS and human MGA [1].

High impact information on MGA

• In Experiment 2, the number of heifers conceiving to AI following the MGA/PG estrous synchronization regimen was increased by mass insemination of all heifers not exhibiting estrus by 72 h after PG [2].
• Two experiments were conducted to determine the conception rates of heifers time-inseminated following melengestrol acetate/prostaglandin F(2alpha) (MGA/PG) estrous synchronization treatment [2].
• Estrus was synchronized with either a progestin compound (MGA) or by the use of a luteolytic agent (PGF) [3].
• Collectively, these trials do not provide strong support for a single injection of FSH, as used here, nor does it indicate a clear advantage for either MGA or PGF as a means of enhancing the ovulation rate or embryo quality [3].

Biological context of MGA

• In cyclic heifers, timed insemination can increase the percentage of heifers pregnant after being synchronized with MGA/PG [2].

Analytical, diagnostic and therapeutic context of MGA

• Synchronized pregnancy rates were 55.2, 32.4 and 15.2% for the 14-d MGA, 7-d MGA and control groups, respectively [4].
