INFLUENCE OF BOOR GENOTYPE ON HEMATOLOGICAL AND BIOCHEMICAL INDICATORS OF BLOOD IN HYBRID PIGS
Purpose of research: In the process of growth and development of pigs, to study the hematological and biochemical parameters of the blood of young pigs obtained by combining two breed sows with purebred and hybrid boars.
Material and research methods. The studies were carried out at the State Agrarian University of Moldova and at the pork production enterprise "SC Agroseminvest SRL".
To achieve the goal, the research material was two breed sows large white x Landrace (maternal form) and purebred and hybrid boars: I-pietrain; II-large white x landrace x pietrain; III-(large white x landrace x pietrain) x pietrain; IV-duroc; V-pietrain x duroc, (paternal form). In order to determine the influence of hybrid boars on the growth and development of the offspring, five experimental groups were formed according to the principle of analogs of 6 sows and 30 heads of young animals (15 pigs and 15 castrates).
Research results .The data obtained indicate an insignificant increase in the hemoglobin content in group I in comparison with group V animals with a moderate significance of the difference, which was 4 g/l (B ≥ 0.95). Consequently, in groups where meat breeds Pietrain and Duroc were used in various combinations, the hemoglobin content was higher. The best results in terms of the content of erythrocytes were obtained in groups III and V, respectively 7.61 x 1012 и and 7.59 x 1012, and a significant difference was established between groups III and IV (B ≥ 0.99), while in the second group the content of erythrocytes was 0.39 lower than in group III (7.22 x 10¹²). Reliable data on the ALT content were obtained between young pigs of groups I and V (B ≥ 0.95). Some tendencies towards a higher content of AST in the second group have been established. The blood glucose level in hybrid young animals in different combination combinations ranged from 5.68 mmol/l (group I) to 6.19 (group II), and the calcium level from 2.55 mmol/l (group III) to 2.81 mmol/l (group II) with a moderate tendency to increase these indicators in group II.
- A higher hemoglobin content was found in the I group of animals in comparison with the V group with a moderate significance of the difference, which was 4 g/l (B ≥ 0.95). A significant difference was established between groups III and IV (B ≥ 0.99).
- A higher content of protein in the blood is found in groups I–II, and is more than 89 g/l.
- In hybrid young animals, the glucose level in different combination combinations ranged from 5.68 mmol/l (group I) to 6.19 (group II), and the calcium level from 2.55 mmol/l (group III) to 2.81 mmol/l (Group II) with a moderate tendency to an increase in these indicators in group II.
