“…Osteoarthritis lesions occurred in more than 80% of the animals with a calcium-deficient diet (Heinola et al . 2006 ). Similarly, other authors have reported osteochondrosis-type lesions in feedlots and bull stations where the feed given was thought to be one of the causative factors (Jensen et al .…”

The north-western part of South Africa, in particular, is well known for mineral imbalances. Aphosphorosis, resulting in rickets and osteomalacia, received a lot of attention at the turn of the nineteenth century (1882–1912). This was followed in 1997 by research on Vryburg hepatosis, another area-specific mineral imbalance–related disease in young calves reared on manganese-rich soil derived from the weathering of dolomitic (carbonate) rock formations. In 1982, a totally new syndrome (osteochondrosis) manifested in, amongst others, areas in South Africa where aphosphorosis was rife. Osteochondrosis was also identified in the south-western parts of Namibia as well as southern Botswana and other areas in South Africa. Osteochondrosis has a multifactorial aetiology and this study focused on the role of minerals, particularly phosphorus, in the development of the disease. A significant improvement in the clinical signs in experimental animals and a reduction of osteochondrosis occurred on farms where animals received bioavailable trace minerals and phosphorus as part of a balanced lick. An increase in the occurrence of the disease on farms during severe drought conditions in 2012–2013 prompted researchers to investigate the possible role of chronic metabolic acidosis in the pathogenesis of the disease.

“…Results of a recent study even indicated that a single ruminal acidosis event can cause a prolonged decrease in semen quality (Callaghan et al, 2014). Grain can be high in phosphorus, and diets with low calcium to phosphorus ratios have been shown to predispose to osteoarthritis and lameness (Heinola et al, 2006). Other vitamin and mineral imbalances have also been associated with osteochondritis dissecans (Davies and Munro, 1999).…”

In pasture-based, seasonally calving dairy herds of southern Australia, the mating period usually consists of an initial artificial insemination period followed by a period of natural service using herd bulls. The primary objective of this study was to identify associations between individual bull- and herd-level management factors and bull fertility as measured by a pre- and postmating bull breeding soundness evaluation (BBSE). Multivariable mixed effects logistic regression models were used to identify factors associated with bulls being classified as high risk of reduced fertility at the premating and postmating BBSE. Bulls older than 4 yr of age at the premating BBSE were more likely to be classified high risk compared with bulls less than 4 yr of age. Bulls that were in herds in which concentrates were fed before mating were more likely to be classified as high risk at the postmating BBSE compared with bulls that were in herds where concentrates were not fed. Univariable analyses also identified areas in need of further research, including breed differences between dairy bulls, leg conformation and joint abnormalities, preventative hoof blocking for bulls, and mating ratios.

“…Сперматогенез у быков происходит непрерывно в течение всего года и зависит от нейрогуморальной регуляции организма и его индивидуальных особенностей. Для долголетней племенной службы быков, с сохранением хорошего качества семени, высокой половой активности, необходимо обеспечить их полноценным белком, макро и микроэлементами, витаминами [5,6]. С этой целью используются различные кормовые добавки как импортного, так и отече-ственного происхождения.…”

The seed bulls used for artificial insemination should be in good health, have outstanding genetic characteristics, have high sexual activity, and the biological products ob-tained from them should have high quality indices. One of the possible methods of increasing semen production is the introduction of dietary supplements into the diet. The intro-duction of new feed and biologically active supplements into the diet may cause both positive and negative changes in metabolic processes. Monitoring the biochemical status of blood allows detecting not only metabolic disorders in highly productive animals but also a lack of vitamins, mac-ro-and microelements. The research goal was to study the effect of a natural biostimulant (mineral supplement) made from maral antler press-cake on the blood biochemical indices ofBlack Pied seed bulls in the breeding company AO “Plempredpriyatiye Barnaulskoye”. Along with the basic diet, the seed bulls of the trial group received the natural biostimulant (mineral supplement) based on maral antler press-cake; the daily dose -15.0 g per head, for 30 days with 10 days’ interval after each application. The supple-ment was thoroughly mixed with compound feed before feeding. The mineral supplement is of powder form and contains a complex of vitamins, minerals, amino acids and other biologically active substances. The use of a mineral supplement increased the amount of total protein and al-bumin by 7.15% and 18.3%, respectively. The blood glu-cose level in the seed bulls of the trial group was higher by 12% and cholesterol by 17.1% than in the blood of the con-trol group animals. Cholesterol of the seed bulls may be used as a structural material or a precursor in the synthesis of sex steroid hormones. The level of total calcium, alkaline reserve at the end of the experiment increased in the seed bulls when using the mineral supplement made from maral antler press-cake in the diet by 4.8% and 8.1%, respective-ly, as compared to the control group.
