RESUMEN

cDNA was prepared from the mRNA isolated from sheep anterior pituitary glands. On cloning cDNA in E. coli, a clone coding full sequence of sheep pre-growth hormone was determined. The sequence for the sheep growth hormone (GH) is in agreement with the amino acid sequence of the protein determined previously except for the asparagine residue at position 99 rather than aspartic acid and the arginine residue at position 146 in place of threonine. The cDNA sequence presented is also in accordance with the genomic sequence for the sheep GH gene that has been reported.

RESUMEN

Six Barbari goats each were assigned randomly to treatments 1,2 or 3, comprising im injections of FSH (folltropin) at 12, 14 or 16 mg dose level respectively. Estrus was synchronized with intravaginal sponge impregnated with flugestone acetate (30 mg; chronogest) inserted for 12 days and cloprostenol (125 micrograms) im at the insertion as well as at removal of sponge. FSH treatment started 48 hr before the sponge removal as 4-day declining dose scheme. Estrus could be effectively synchronized in all goats under the study, with significant difference (P less than 0.05) in the onset of estrus between the treatment groups. All goats were administered with 750 IU hCG i.v. at estrus. Recording of ovarian response and embryo recovery was done 45 hr after the onset of estrus. The prime aim of superovulation was effectively achieved in Barbari goats with the use of chronogest implants and folltropin. There was no difference (P greater than 0.05) between the treatment groups in recovery of transferable embryos, however, 14 mg folltropin appeared to be near optimal dose. There was no adverse effect on the quality of recovered embryos with high doses of folltropin.
