Avian reproductive behavior is regulated through the neuroendocrine system. The transition from laying to brooding is strictly controlled by the hypothalamus-pituitary-gonadal (HPG) axis. Cross talk on the HPG axis relies on the circulatory system, where

Effect of humidity on the life cycle and reproduction of Dermacentor reticulatus (Ixodidae) in laboratory mice [PDF]
The reproductive cycle of Dermacentor reticulatus (Ixodidae) is described in this paper. Experimental infestation was carried out on immobilized (fixed) RAP mice and those that could move freely. Dermacentor reticulatus (D.

Blood biochemical parameters of simmental cows in different phases of reproductive cycle [PDF]
This paper presents the values of blood biochemical parameters of Simmental cows (n = 60), divided into five groups (dry cows, early puerperium, late puerperium, the fifth month of lactation, and cows with an extended service period). The ration
