An experiment was conducted to examine the effect of fatty acid concentrate (FAC), as a new source of energy and carnitine on performance, physiological condition and meat quality of broiler chickens. In experiment there were four groups of 80 chickens of cross Hubbard each (males: females=40:40) in age period 0-41 days. 1 group (control) received in during the periods 0-14, 15-28 and 29-41days, sunflower oil (SO) respectively 5.34%, 5.50%, and 6.10%, group 2 received the same amounts of FAC instead SO, 3 group - mixture SO:FAC (50:50), 4 group -FAC + 0,25% carnitine. Final body weight: 1 group = 2574±29 g, 2 group FAC= 2553±27 g 3 group SO + FAC = 2531±34 g., 4 group FAC+0,25 carnitine = 2520±34 g. Feed conversion, digestibility of nutrients, blood hematology and biochemistry, the condition of organs, meat quality and cutting of carcass of chickens on FAC had no any differences from the same signs in chicks on SO. Carnitine had a positive effect on chicken growth only in the period 0-14 and less 15-28 days; in the period 29-41 days daily gain was below, than that in 1-3 groups. Canitine reduced the content of liver fat. Outcome: FAC is a satisfactory source of energy, comparable with vegetable oils. The price of FAC is 30% lower in comparison with sunflower oil and soybean oils, therefore its use in broiler poultry farming instead of vegetable oils will be of great economic importance

The main diseases of lactating cows occur in the first two months of lactation, i.e. during the production peak of productivity. They are caused by the changes in metabolism during the transition period, which are not supported by adequate changes in the organization of feeding, or rather sufficient to ensure cows with nutrients, which causes a number of closely related diseases. To allocate any of them is not possible, as their manifestation depends on a number of reasons, and depending on situation may prevail one or the other. Among the most common diseases, there are ketosis, milk fever (paresis of maternity), dysplasia of the abomasum, acidosis, mastitis, endometritis, laminitis and leukemia. These diseases cause the greatest problems in herds with high productivity, and are caused by changes in metabolism in cows in the transition period and the inability to properly feed the animals at this time. To identify the causes of these diseases we do not need to study each of them individually - it is enough to deal with the peculiarities of metabolism. This period includes the month before calving and the first or second month of lactation, but the most important are 3 weeks before calving and 3 weeks later. In order to prevent metabolic disorders there were developed and tested feed for feeding cows before calving and immediately after calving. Their effect was studied on milk production and health status
