“…An optimal task of feeding is use of feedstuff mineral supplements that have positive effects on the animal organisms and improve growth (Pal et al, 2021;Szacawa et al, 2022) and also slaughter parameters (Ward & Spears, 1997). Da Silva Zornitta et al ( 2021) do not recommend using injected microelements on animals under stress during the weaning phase, because it did not improve meat productivity and biochemical variables.…”

Correct nutrition with sufficient amount of optimal doses of microelements efficiently supports high levels of beef production and health of the animals throughout the feeding period. In the sphere of beef production, microelements are needed as additional supplements to play an important role in the productivity of cattle and the quality of the products made from them. Providing cattle with a more bioavailable source of deficient microelements could increase the metabolic process of the main nutrients, which would affect the intensity of bull growth and slaughter meat parameters. It has been revealed that organic complexes of deficient microelements have greater bioavailability. Throughout the experiment, Ukrainian Black Spotted bulls of 175–200 kg live weight were fed with diets enriched by chelate compounds of microelements with lysine and methionine. Animals of the second group were fed a diet with methionates of microelements in the following doses, mg/kg of live weight: iron – 0.05, cobalt – 0.04, iodine – 0.05 and selenium – 0.02; the third group received lysinates in the same doses of microelements; and the fourth group was given lysinates and methionates in a complex with half-doses of microelements. The studies were carried out using the following methods: zootechnical (productivity), biochemical (chemical blood composition), morphological (weight and sizes of certain tissues and internal organs), physical-chemical and sanitary meat parameters and statistical (mean arithmetic value and its error, significance level of difference between parameters). We found evidence and confirmed the benefits of using microelement supplemention with essential aminoacids in the bulls’ diet. Feeding chelate supplement to animals during the second feeding period improved hematological parameters, the productivity and nutrition value of beef. We determined that the best outcomes resulted from feeding bulls with lysinates and methionates in complex with microelements (Fe, Co, Se and I) during the second feeding period. The animals had 26.0% higher mean daily increments and 11.1% greater growth rates, and they grew 25.8% more intensively than the others that consumed only the main diet. The animals of this group had 5.2% higher slaughter yield and 4.8% higher carcass yield. The experimental groups were observed to have lower number of microorganisms in the longissimus layer in one field of view when analyzing impression smears. After 14 days of beef storage, qualitative reactions in the control group were positive with formaldehyde, sulphuric-acid copper, Nessler’s reagent and negative with benzidine. The reactions in the samples from experimental groups were doubtful. Less deterioration of beef stored at low positive temperatures (0…+2 ºС) was observed for the samples of experimental groups.

“…Results showed a linear increase of milk production, as well as total milk solids (fat and protein) in the Zn supplemented groups [24]. Supplementing Zn at levels of 40 or 80 mg/kg DM (as ZnSO4 or Zn hydroxychloride) in pre-ruminant crossbred calves (starting age 10 days) significantly improved growth performance (body weight, average daily gain and body length) when compared to non-supplemented animals after a 90 days period [25]. When considering Zn effect on reproduction, in a study with lactating dairy cows results showed that supplementing 80 or 120 mg/kg DM of Zn (as ZnSO4) for 90 days (45 days before and 45 days after calving) significantly improved reproductive efficiency (reduction in postpartum estrus interval, days to first insemination, service period, service per conception and increased conception rate) in both supplemented groups compared to no supplementation [26].…”

Dietary inclusion of trace minerals (TM), such as copper (Cu), manganese (Mn) and zinc (Zn) is of importance to cover the ever-evolving requirements for growth, production, and reproduction in ruminants. Various sources of TM are commercially available, such as inorganic (ITM), organic (OTM) or hydroxy (HTM) forms, however their bioavailability and efficiency to improve ruminant zootechnical parameters may be highly influenced by ruminal solubility and effects on the rumen environment. The objective of this review was to compile the most up-to-date information on the ruminal solubility of ITM, OTM and HTM, and their effects on fermentation parameters and rumen microbiota, aiming to support specialists from the animal feed industry when choosing TM products for ruminant supplementation. Some commonly used ITM sources, like sulfates, have a high ruminal solubility, while oxides are less soluble. The ruminal solubility of OTM is mostly found to be high, however data on these TM forms are still lacking. Regarding HTM, ruminal solubility is reported to be low, nevertheless results are inconsistent. Considering rumen fermentation, ITM show a negative effect, OTM might improve, while HTM do not affect parameters like dry matter degradability, volatile fatty acid production, pH, or microbial protein synthesis. As to rumen microbiota, ITM do not affect microbial populations; OTM could decrease abundance of some specific bacteria, like fibrolytic microorganisms, while studies with HTM are missing or inconclusive. Further research is necessary to better understand the ruminal solubility kinetics of TM sources and the different interactions with fermentation parameters and rumen microbiota to successfully apply precision TM supplementation of ruminants, tackling deficiency occurrences.
