Comparative Study of Lactogenic Effect and Milk Nutritional Density of Oral Galactagogue in Female Rabbit.

BACKGROUND

Hypogalactia and agalactia in lactating mothers are the major causes of child malnutrition, mortality, morbidity, and overall ill health. The development of such treatments requires a well-designed preclinical study with suitable laboratory animals, which needs to be improved. Thus, a suitably designed study with a laboratory animal to analyse galactagogue activity, along with an assessment of the quality and quantity of milk, is required.

OBJECTIVES

This study aimed to evaluate the potential of rabbit as an animal model for studying lactogenic activity.

METHODS

The structural homology of prolactin, gene prolactin receptor, and prolactin hormone in humans, rabbit, and rat was studied using BLAST and PyMol to assess similarity in the lactogenic system. Daily and cumulative milk production and pre-treatment (control) and post-treatment (three drugs) in rabbits were recorded and evaluated by analysing protein, fat, lactose, solid non-- fat, and ash values. All parameters were recorded on the 0th day and at the end of weeks 1, 2, and 3. Mammary gland histopathology was performed to evaluate the effects on mammary glands.

RESULTS

Homology studies revealed that the sequences of the human and rabbit prolactin genes, receptors, and hormones had a high similarity index. Treatment with Domperidone, Metoclopramide, and Shatavari significantly enhanced milk production by enhancing prolactin secretion; only Shatavari increased milk nutrition. Enlargement of the tubuloalveolar ducts of the mammary glands was observed.

CONCLUSION

Our findings suggest that rabbits are robust, reproducible, ethically superior, and preclinically relevant animals for assessing lactogenic activity.
