R.  aPlasma luteinizing hormone levels and testis diameters of ram lambs of different breeds.h[electronic resource]  c1975  aAbstract: Plasma LH levels were examined at 1 1/2-hr intervals in ram lambs of the Finnish Landrace, Border Leicester and Cheviot breeds on three occasions at 3-week intervals by radioimmunoassay. On each occasion, the mean plasma LH concentration was found to be significantly higher in the Finnish Landrace than the other two breeds, although big variations occurred between individual samples in the same animal. This form of hormonal pulsatile release was most marked in the Finnish Landrace lambs. Testis growth was also measured and was found to be correlated, independently of body weight, with LH concentration on the final sampling occasion.  aBody weight  aHorses  aImmunology  aLuteinizing hormone  aPhysiology  aRadioimmunoassays  aSheep  aHormônio  aOvino  aDiametro testicular  aRacas  aSpecies Specificity1 aLAND, R.
