This study was done to assess oxidative stress and haematologicalparameters of twenty male goats aged between eight and 22 months of the West African Dwarf breed reared under twomanagement systems. Ten bucks were reared under an intensive system, and another 10 bucks reared under an extensivesystem were used. The Hb concentration obtained in both groups was significantly (p<0.05) higher in the intensively managedgoats (12.39±0.02 gm %) compared to the extensively managed group. The total erythrocyte count in intensive goats, 35.34±1.36×106/μl, was significantly (p<0.05) higher than the value recorded in the extensive group (30.01±1.41×106/μl). Therecorded leucocytes counts in intensive goats of 10.26±0.70×103/μl was significantly (p<0.05) lower than 12.38±1.23×103/μlrecorded in the extensively managed goat, while the calculated value of MCV in intensive goat (9.8±0.73 fl) was significantly(p<0.05) higher than the recorded value in extensive group. The obtained value of MCH was significantly higher (p<0.05) in theextensively managed goats. The recorded neutrophil value of 5.00±0.50×103/μl in extensively raised goats was significantly(p<0.05) higher than 3.70±0.20×103/μl obtained in the intensively raised group likewise the lymphocyte count of 5.60±0.08 ×103/μl in intensively raised goats was significantly (p<0.05) lower than the value obtained in the extensively raised goat. The neutrophil:lymphocyte ratio was significantly higher (p<0.05) in the extensive versus the intensive group viz. 0.75±0.03 asagainst 0.67±0.04. In the extensive group a higher malondialdehyde (MDA) value of 2.30±0.07 ng/ml was recorded and this was significantly (p<0.05) higher than the corresponding value of 1.28±0.11 ng/ml obtained in the intensively managed goats. The recorded value of superoxide dismutase, catalase and glutathione peroxidase was significantly (p<0.05) higher in theextensive group than those on the intensive group. The fragility test of the extensively managed goats shifts more towards rightand was significantly (p<0.05) highest at a sodium chloride concentration of 0.2-0.7% in extensively managed goats. It can beconcluded from the present study that the biomarkers of oxidative stress were higher in the extensively than the intensively managed goats.

In the conditions of the Republic of Belarus there was determined the productivity and foraging advantages of fodder galega (Galega officinalis) in comparison with the traditional perennial leguminous grasses (alfalfa (Medicago sativa); alsike clover (Trifolium hybridum); cookshead (Onobrychis viceaefolia)) and influence of the analyzed crop of state and internal microbiota of agricultural animals. There was studied the qualitative structure of galega in accordance with the phases of crop development and its influence on physiological functions of animals. It is established, that in the conditions of northern region of Belarus the fodder galega provided the yielding capacity of dry matter of 11,3 t/ha that exceeded the indices of alfalfa on 13,9%, alsike clover - in 2,7 times and cookshead - in 2,1 times. By the third decade of May it formed 18-20 tons green mass that made it possible to feed animals on 10-15 days earlier, than with other leguminous grasses. High degree of leafage (65,7%) preconditioned its high nutritional value. Fodder galega has high level of calcium, potassium, phosphorus and some microelements: copper, zinc, manganese, cobalt. Studying of vitamin value of fodder galega showed that its green mass was vitamin-rich, had enough of irreplaceable amino acids. It was established, that hay of fodder galega had high level of the non-decomposed protein (68,6-71%) that was very important for feeding of highly productive cows. It increased the level of crude protein in experimental animals on 8%.
