母羊血浆褪黑激素浓度的遗传变异来自松果体重量的变化。这项研究调查是否是由于松果体细胞的数量，或在其大小的差异。两组羔羊出生前被分配到极端（18高和21低）通过计算其遗传值的基础上，其父母的褪黑激素浓度。羔羊从1周龄至14周龄流血的。记录松果体、脑和垂体重量、脑的长度和宽度以及下丘脑的长度。遗传组间方差分析（P
Genetic variability in plasma melatonin concentrations in ewes results from variations in pineal weight. This study investigated whether it is due to a difference in the number of pinealocytes, or in their size. Two groups of lambs were assigned before birth to being extremes (18 High and 21 Low) by calculating their genetic value on the basis of the melatonin concentrations of their parents. Lambs were bled from I week of age until 14 weeks of age. Pineal gland, brain and pituitary weights, length and width of the brain, and length of the hypothalamus were recorded. A significant effect (ANOVA) of genetic group (P
