Abstract
The article covers addition of chlorella suspension, its effect on nitrogen balance, digestibility of nutrients and amino acids, pig productivity. Various feed additives, micro-element mixtures, and vitamins are used in animal nutrition to deal with the deficiency ofcertain vitamins and mineral elements in the rations. The peculiarity of chlorella suspension as a feed additive is in the ability to cultivate it throughout the whole year and in the availability of optimized technologies for its cultivation and use. Chlorella suspension is rich in proteins, minerals, vitamins, fatty acids and fiber. Introduction of chlorella suspension into pigs’ diets has helped to increase the digestibility coefficients of both inessential (by 7.5 %) and essential (by 2 %) amino acids. Feeding the animals with chlorella suspension has also resulted in the release of nitrogen retained in animals’ bodies by 13 % compared to the control group. The additional use of chlorella suspension in the diet of fattening pigs (large white) was found to increase the average daily gain by 21.9% compared to the control group which did not receive chlorella suspension. The conversion of animal feed to obtain 1 kg of live weight gain in the control group was 5.1 kg, in the experimental group - 4.2 kg, and the conversion rate of feed in the experimental group was higher by 21.4 %.Feeding young pigs with chlorella suspension increases the digestibility of protein by 4.5 %, fiber by 2.0 %, fat - 0.7 %, essential amino acids - 81.6 %. The introduction of chlorella suspension to pig rations leads to an increase in the level of nitrogen in their body by 54.7 %of that taken with feed and 69.15 % of that digested in the body. Pork production profitably using chlorella suspension stood at 12.3 % , which is more by 87,8 % compared to the control group.
Highlights
Today, scientists and specialists in the pig industry all over the world are focused on finding the most efficient ways of use, which cover two-thirds of pork production costs
The basic diet for fattening pigs was cost of livestock products, and realizing the genetic applied in the control, whereas in the second potential of an animal's body is possible only using high- experimental group chlorella suspension was added to quality and full-fledged feeds that include various watering according to the study scheme
The cost per 1 kg of gain in fattening pigs using chlorella suspension was lower by 18 % compared to the control group, and the average daily gain in the experimental group was by 21.9 % higher than in the control group
Summary
Scientists and specialists in the pig industry all over the world are focused on finding the most efficient ways of use, which cover two-thirds of pork production costs. The article presents study results of the effectiveness of chlorella suspension as a source rich in proteins, minerals, fatty acids and fiber. It contains many vitamins, polyphenols and other components that have a positive effect on animals’ bodies. Production practice shows that most animals grow much slower than they are physiologically capable to do This is mainly due to the lack of biologically active substances in animals’ rations. When creating each new type of feed additive it is necessary to test its effectiveness in animal nutrition The advantages of this feed additive are in the ability to cultivate chlorella throughout the year, the availability of optimized technologies for its cultivation and use. The main period lasted additives of mineral origin are used in farm animals’ 60 days
