Abstract

A person should take about 90–100 g of protein day, largely from animal sources, despite the growing need for vegetable protein. Animal feed with insufficient protein causes them to consume excessive amounts of fodder, increasing their need for plant protein. The production of plant protein must significantly expand in order to fulfill the demands of animal husbandry. The demand for vegetable protein is on the rise, and it is recommended that an individual should consume approximately 90-100 g of protein per day, primarily sourced from animals. Insufficient protein in animal feed results in a higher consumption of fodder, which in turn necessitates an increased intake of plant protein. The experiment took place at the Tashkent State Agrarian University's experimental farm, located in typical gray soil conditions. The soil consists of a 25cm driving layer and a 50cm humus layer, with 1% humus, pH level of 7, and mobile phosphorus, chlorine, and nitrogen levels of 1.5-2.9 mg/100g, 22-25 mg/100g, and 3.8-4.2 mg/100g, respectively. It was found that the nutritional quality of alfalfa is also influenced by its growth stage, with the highest protein content observed in the stem growth phase in the Tashkentskaya-1728 variety. By the time of flowering, the protein content has decreased significantly.
