The composition of artificial milk varies depending on the lamb's age. For lambs under 20 days old, the formula includes 68% skimmed milk, 29% fat, and 3% phospholipids. From 20 to 40 days of age, the ratio changes to 80% skimmed milk, 17% fat, and 3% phospholipids. This adjustment supports the growing nutritional needs of the lambs as they develop.
In terms of additives, per 1000 kg of artificial milk, the following are included: 1.2 g of cobalt chloride, 20 g of copper sulfate, 0.3 g of potassium iodide, and 0.2 g of sodium selenite. Additionally, 10 kg of mineral salts and 5 kg of bicarbonate are added. Vitamins are also essential—20 million units of Vitamin A, 6 million units of Vitamin B, 2 million units of Vitamin E, 1.5 grams of Vitamin B1, 1.5 grams of Vitamin B2, 750 mg of Vitamin B6, and 1.25 grams of Vitamin B12. For amino acids, 1 kg of lysine and 2 kg of methionine are included to support muscle development. Bioactive substances such as chlortetracycline (50 g), enrofloxacin (50 g), and methylated hydroxytoluene (70 g) are also added for health and preservation purposes.
After weaning, each lamb is initially fed 5 kg of green grass and 0.5 kg of concentrate. Starting from day 20 post-weaning, their diet transitions to 2.5 kg of a mixed feed consisting of 80% hay powder and 20% concentrated feed daily. This feeding regimen results in an average daily weight gain of 173 grams, with each kilogram of weight gain requiring approximately 8.2 kg of feed.
In large-scale sheep farming systems abroad, farms can accommodate between 3000 to 5000 sheep. These facilities often feature a two-tier design, with an upper floor that allows droppings to fall through gaps, reducing disease risk. A scraper conveyor system transports pellet feed, while a long-flowing water tank ensures constant access to clean drinking water. The lower floor is equipped with a scraper-type cleaning machine for efficient waste removal.
Lambs are typically weaned between 60 to 120 days after birth. After 76 days of fattening, the average daily weight gain reaches 230 grams. At the end of the fattening period, the lambs weigh between 34 to 40 kilograms, with a slaughter rate of 47.6%. This efficient system helps maximize productivity and profitability in commercial sheep farming.
