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
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
