The model of doe-rabbits nutrition based on using antioxidants in liposomal form with iodine content

The research objective was studying biological effect of liposomal form of antioxidants on the basis of seaweed with the content of iodine on reproductive signs of doe-rabbits and biochemical status of blood serum. The scheme of the research: the first group of doe-rabbits - control - the main diet (MD); the second group - experimental - MD + liposomal form of antioxidants with the content of organic iodine from laminarias of the White Sea (Laminaria digitata) at the rate of 250 g of substance on 1 t of fodder mix, was involved in the course of preparation of granules (the content of iodine bioavailable - 600 thousand mkg/t); the third group - MD + liposomal form of antioxidants with the content of organic iodine from seaweed (Cystoseira barbata) of the Black Sea at the rate of 250 g on 1 t of fodder mix in the form of granules. It was established that the factor of inclusion of liposomal form of antioxi- dants positively affected the level of pregnancy absence in doe-rabbits: in experimental groups practically there were no cases of the birth of dead new borns and abortions. Also this factor positively affected the doe-rabbits with multiple pregnancies: in the doe-rabbits receiving antioxidants on the basis of seaweed of the Black Sea the mass of the nest in 20 days and at weaning was 36.3 % higher. In the latter case also there was positive influence and on nest weight at weaning - for 19.4 %. Practically in all the indicators of biochemistry of blood serum, except amylase, reliable advantage in the doerabbits of experimental groups was noted, besides, the content of iodine made positive impact on the accumulation of hormones of thyroid gland - the relationship between these factors was proved by reliability level for triiodothyronine (4.016 ±0.135 pg/ml, r ≤ 0.05) in the doe-rabbits receiving antioxidants on the basis of seaweed of the Black Sea and on thyroxine in the doe-rabbits of both groups: 14.443±0.180 ng/l (r ≤ 0,05) in the animals of the second group and 16.152±0.649 ng/l (r ≤ 0.01) - the third one.
