Nile tilapia (Oreochromis niloticus L.) fry growth and development effected from feeding with Enzimsporin supplement

УДК 639.3.043.003
Abstract: 

The present research has shown the growth and development of Nile tilapia (Oreochromis niloticus L.) fry effected from feeding Enzimsporin probiotic supplement. During the observation period, the weight of tilapia fry population has increased from 119.5g to 619g in the control group, from 121g to 684g in the 1st experimental group 1 and from 119g to 790g in the 2nd experimental group. Thus, the average daily weight gain per fish is 0.44g, 0.51g and 0.6g, respectively in 22 days. During the observation period an increase in body weight of one fish averaged 3.29±1.63g in the control group, 3.75±1.32g in the 1st experimental group and 4.47±2.40g in 2nd experimental group. During the research period the fry in the 2nd experimental group has shown the highest increase in ichthyomass at the end of the experiment, 9.26g (p≤0.05), which is 2.8g (69.53%) more than in the control group. In the 1st experimental group, the increase is 3.23 g (p≤0.05), which has exceeded the indicators of the control group by 0.8 g (75.23%). The outline fish indicators correspond to the general statistical values of tilapia fry development in the given age period.

Hematological Blood Values of Store Pigs According to the Automated Analysis Data

Abstract: 

Pig breeding, as an independent livestock sector in Russia, has been developing steadily since 2008. This was facilitated by the adoption of the agricultural development program, which assumed an increase in state support for the agro-industrial complex. However, the intensification of pork production places high demands on the quality of livestock, which necessitates the use of breeds, types and lines that can withstand the loads of modern industrial technology without reducing productivity. The article presents the morphological parameters of the peripheral blood of store pigs of large white breed, obtained using a hematology analyzer. Based on the analysis of the data obtained, the authors have came to the conclusion that there is a tendency to an increase in the number of erythrocytes and hemoglobin, and a decrease in the number of leukocytes and platelets with age in the blood of fattening pigs. These changes can be associated with high growing capacity of fattening piglets and the implementation of effective preventive measures on the farm in relation to piglet anemia.
