Biochemical and hematological characteristics of blood indicators, productivi-ty of piglets under the influence of additional feed “Activo”

Abstract

The article discusses the issue of the condition of the piglets' bodies before and after weaning after feeding the additional feed “Activo.” The object of the study was piglets born from sows of the large white breed of ADN genetics. Piglets were divided into control (n = 111) and experimental (n = 110). From the 5th to the 43rd day of life, the piglets were given pre-starter compound feed in loose form. In the research group's pre-starter compound feed, “Activo,” was introduced in the amount of 0.2 kg/t of finished compound feed. Blood was collected from the cranial vena cava of the piglets of the control and experimental groups for biochemical and hematological parameters on the 28th and 43rd days of the piglets' life. Productivity control was carried out by weighing animals on the day of birth, at weaning, and on the 43rd day of life. Feed consumption was monitored, and average daily gains and feed conversion were determined. According to the results of the research on piglets before weaning, we can see an increase in the total protein level in the experimental group's blood by 2.85 % compared to the control group. The albumin concentration in the control group's piglets was 47.33 %, and the experimental group was 48.00 %, which is 1.42 % more than the control group. There was also an increase in α-, β-, and γ-globulins in the experimental group. After piglets were weaned, a probable increase in total protein and albumin was noted in the experimental group by 3.96 % and 1.85 %, respectively, in the control group. At the beginning of the experiment, the piglets of the control and experimental groups had a slight difference in live weight, which was 3.35 % in favor of the control group. Already on the 28th day of life, the piglets of the research group had a live weight statistically higher by 6.58 % (P < 0.001) concerning the control. Thus, for 14 days of the experiment after weaning, the increase in live weight of piglets of the experimental group probably increased by 11.9 % (Р < 0.01), and the difference in the weight of piglets between the control and experimental groups was 0.88 kg, or 8.15 % (P < 0.001). The average daily growth rate of piglets in the experimental group also increased by 11.8 % (Р < 0.01). The difference in feed conversion between the control and experimental groups is 0.19 kg or 10.8 %.
