The winter diet should increase the metabolic energy content and appropriately reduce the protein to energy ratio. To do this, feed more corn. Because there are few green and green vegetables in winter, carrots and multivitamin additives should be supplemented to prevent vitamin deficiency and affect egg production.
In addition, for hens of different ages, some irritating substances may be properly added to the feed to increase the egg production rate. It has been reported that laying hens aged 150-200 days add 55-60 grams of succinic acid per about 10 kilograms of bran feed; layer chickens over 340 days of age add 3.5-4 per about 10 kilograms of bran feed. Vitamin B2 and 25-30 grams of vitamin B12 can increase chicken egg production by about 11%.
