INFLUENCE OF KAFI PREPARATION ON WOOL AND SHEEPSKIN PRODUCTIVITY OF YOUNG SHEEP
The main purpose of the work was carrying out the early weaning technology of 2 month old lamb with the use of the special immunomodulator – KAFI and the research of this preparation influence on wool and sheepskin productivity of experimental animals as well. The scientific exploration was performed in the conditions of commercial sheep farm Kropivna in Cherkasskaya oblast. In March 40 lambs of the Precose breed of two month age were selected and using the principle of analogy four experimental groups were formed, one of which was a control group. After the week of equalizing period the lambs were weaned from ewes and were injected with the KAFI preparation by an intramuscular injection (in the control group with physiological solution). It was established that the highest growth rate was in the lambs of the 3rd experimental group. At the age of 4 months their body weight was 27.45 kg against 24.40 kg in the control group. It is by 12.5% more (P>0.99). The highest growth of wool rate of the lambs was determined at the period from 2 to 5 months. Their natural wool length was 8.70 ±0.15 cm against 6.23 ±0.18 cm in the control one. The indicators of thinness, quality and strength of wool were almost the same in all groups and statistically invalid. It was determined that the average weight and the area of sheepskin received from the lambs of this experimental group were much higher and matched 4.2 kg and 130.6 dm² against 3.9 kg and 111.6 dm² in the control one. Therefore, the KAFI is a long acting preparation and has a great influence on further growth, development and productivity characteristics of young sheep. The immunomodulator KAFI by its injection into animals’ organism promoted the better growth and clip in the lambs of the 3rd experimental group (dose 0.4 ml/head) and it was 3.22 kg, it is by 0.7 kg or 28% higher than in the control group. The sheepskins received from animals of the 3rd experimental group were larger (130.6 dm 2 against 111.6 dm 2 in the control group) and with considerably longer wool (3.06 cm against 2.16 cm in the control group).
