The results of studies of morphofunctional changes in the external secretory apparatus of the pancreas of broiler chickens of the Smena-9 cross (age 42 days) are shown. 7.5% white lupine was introduced into the diet of chickens as an alternative protein source. Lupine is characterized by a high content of crude protein (40%) and fat (17%), as well as a low level of trypsin inhibitors (0.08–0.16 g/kg). This ensures high digestibility and economic feasibility of this feed in comparison with soybean and sunflower meal. A control group (feeding with standard mixed feed with sunflower meal) and an experimental group were formed. Histological analysis was performed using hematoxylin-eosin staining, morphometry was performed using a light-optical microscope. A statistically significant increase in acinus area by 12.5% (p <0.02), acinar cell height by 21.1% (p <0.01), intra-valvular duct diameter by 9.7% (p <0.02) and inter-valvular duct lumen area by 14.8% (p <0.01) was found, indicating hypertrophy of secretory elements and optimisation of pancreatic juice evacuation. The absence of dystrophic and inflammatory changes confirms the stimulating effect of lupin in this dose on the exocrine function of the gland. Lupine helps to increase the digestibility of nutrients and the productivity of poultry. Thus, studies substantiate recommendations for the normalized inclusion of lupin in broiler diets to replace traditional protein
supplements.
