Biochemical profile is a set of diagnostic procedures that are based on determining the various reproductive indicators of the animals. Female reproductive physiology is a complex process and the macromolecules produce from females depend upon hormonal regulation and physiological status of the organisms. The measurement of reproductive steroids and their metabolites excreted through urine and feaces serves as purpose of communication and provides new techniques for detection of effective estrus phase in animals. For a better understanding of physiological and biochemical processes correlated to chemical communication in mammals it is necessary to monitor the chemical characterization of pheromones together with biological testing frequently. Hence, the present investigation is designed to analyze the biochemical profiles such as protein, carbohydrate, lipid and steroid hormones such as estrogen, progesterone, LH, FSH in prepubertal, estrus, pregnant and lactating sheep feaces. The level of protein and lipid were significantly high in estrus phase, where as the level of carbohydrate level is significantly high in prepubertal and lactating phases when compared with other phases. Further, estrogen and LH were significantly high in estrus as compared with other phases and progesterone level is significantly high in pregnant phase. Thus, the present work is concluded that biochemical and hormones in estrus phase may represent as important elicit signals to inform the estrus phase of the animals.
