Effects of Probiotic and Enzyme Supplementation on Milk Yield, Blood Profile and Digestibility of Crossbred Dairy Cows in Southwest Bangladesh

The proposed project, titled "Enhancing Milk Yield and Quality Applying Nutritional Biotechnology in Dairy Cows Under Farmer Conditions in Southwest Bangladesh," aims to improve dairy cow productivity and milk quality by supplementing their diets with live yeast and flaxseed. The significance of improving dairy products through nutritional interventions has been brought to light by the growing consumer desire for items that are good for their health. Both flaxseed and live yeast (Saccharomyces cerevisiae), which are abundant in healthful components, have shown promise in enhancing immunity, regulating rumen fermentation, and improving milk quality.

The study's main goals are to improve milk quality and yield while evaluating how these nutritional supplements affect the blood profile and immune system of crossbred dairy cows grown in natural farmer circumstances. We will choose sixteen multiparous lactating cows from farms close to Khulna University. Two distinct feeding trials will be carried out, one concentrating on variable doses of live yeast and the other on different degrees of flaxseed supplementation. Milk yield, composition, body condition scoring, and hematological parameters will all be measured using a randomized complete block design to guarantee statistical validity.
