“…Se is a vital component of selenoproteins (including iodothyronine deiodinase, gluatathione peroxidase and selenoprotein P and W and thioredoxine reductase), which plays an important structural and enzymatic functions Kohrle et al(2007). Se is involved in protein synthesis and the immune system of animal Cortinhas et al (2012) and thyroid hormones metabolism McDowell (2003). A deficiency of Se affects animals living in areas with low natural levels of selenium causes a wide range of health problems including disrupt spermatogenesis, changes of mid-piece architecture leading to breakage of head and tail of spermatozoa and impaired of sperm motility Suttle (2010).…”

The present study aimed to evaluate the impact of administration of zincmethionine and selnomethionine to Friesian bulls during hot summer conditions in Egypt on physiological thermoregulatory response, sexual desire, some physical and chemical semen characteristics and blood metabolites. Twenty sexually mature Friesian bulls were divided into five similar groups (4 bulls/ each). Bulls in the 1 st group were unsupplemented and served as a control, while those in the 2 nd ,3 rd ,4 th and 5 th groups were orally supplemented with zincmethionine (Z-Met) at a levels of 2 and 4 mg/kg of BW/day and selenomethionine (Se-Met) at a levels of 0.3 and 0.6 mg/kg of BW/day, respectively, for two months as preliminary period and other three months as a main collection period. Rectal and skin temperatures, pulse rate (PR) and respiration rate (RR) were measured once each week through the experimental period. During the main collection period, semen was collected twice weekly and evaluated for semen-ejaculate volume (SEV), percentage of progressive sperm motility (PSM), live sperm (LS) and sperm abnormalities (SAB), sperm-cell concentration (SCC/ml) and total-sperm output (TSO/ejaculate). Blood samples were collected pre-treatment and monthly during the main collection period to determine concentration of total proteins (TP), albumin (AL) and globulin (GL); thyroxin (T 4 ), triiodothyronine (T 3 ), cortisol and testosterone hormones and zinc (Zn) and selenium (Se) levels in blood plasma. Also, activity of ALT, AST, ALP, ACP, SOD and GSH enzymes, as well as concentration of fructose, zinc and selenium were estimated in seminal plasma.The obtained results revealed that reaction time (RT) was shorter (P<0.05) and blood plasma testosterone concentration was higher (P<0.05) in all treated groups than the control group, begin the shortest (P<0.05) and highest (P<0.05) values of RT and testosterone concentration were recorded for bulls treated with Z-Met, especially in G3 group. Physical semen characteristics (SEV, PSM, LS, SCC/ml, TSO/ejaculate and SAB) were improved (P<0.05) in all treated groups as compared with the control one, being the best (P<0.05) values for bulls treated with Z-Met, especially in G3 group. Also, bulls treated with Z-Met in G3 group showed the lowest (P<0.05) activity of ALT, AST, ALP and ACP enzymes, highest (P<0.05) activity of SOD and GSH enzymes, and fructose, Zn and Se concentrations in seminal plasma as compare to other treated groups and control one. Bulls treated with Z-Met and Se-Met showed increased (P<0.05) levels of AL, T 4 , T 3 , Zn and Se, while GL and cortisol levels decreased (P<0.05) in blood plasma as compared to control one. In conclusion, orally administration of zincmethionine and selenomethionine to Friesian bulls had a valuable impact on sexual desire, semen quality and blood metabolites. Therefore, it can be recommended to treating the Frisian bulls with zincmethionine at a level of 4 mg/kg of BW/day during two preliminary months and three main semen collection months for improving the ...

“…Cortinhas et al (2012) studied the effect of replacing inorganic with organic sources of zinc, copper and selenium in diets for lactating cows 60 days before to 80 days after partum and observed similar blood concentration of glucose, total protein, albumin, total cholesterol, HDL cholesterol, and urea. No effect of trace mineral source on the activities of AST and GGT was observed, like in the present study.…”

-This study evaluated the effects of organic and inorganic sources of minerals in diets for mid-lactation dairy cows on milk yield and composition, intake and total apparent digestibility of dry matter and nutrients, blood parameters, microbial protein synthesis, and energy and protein balances. Twenty Holstein cows averaging 146.83±67.34 days in milk and weighing 625.30±80.37 kg were used. The experimental design was a crossover. Diets were composed of corn silage (50%), ground grain corn, and soybean meal, differing with regard to the sources of trace minerals, plus an organic and inorganic mix. The organic mineral source increased milk fat and fat-corrected milk yield without changing milk yield, intake, or total apparent digestibility. Blood parameters, microbial protein synthesis, and energy and protein balances were not affected by the sources of minerals. Organic sources of minerals improve milk fat yield without affecting other parameters.

Effect of feeding chelate complexes of trace elements on the average daily balance of Cu, Zn and Mn in the organism of cows during the period of lacta-tion

The questions are considered about the effect of feeding of trace elements of different types and concentrations in premixes on the average daily balance of copper (Cu), zinc (Zn), manganese (Mn) in the organism of cows of Ukrainian black mottled dairy breed of the two months after calving. For the experiment, 40 cows were selected and formed four groups: one control and three experimental. The cows in the control group fed a premix of sulfate salts of copper, zinc and manganese in doses that are 100% covered their lack in a forage. Experimental animals from I, II and III groups were fed premixes with chelate complexes of Cu, Zn and Mn, which offset the deficiency of trace elements in the feed ration for 100, 50 and 25% (calculated on pure element), respectively. The diet was counted on a cow with an average live weight of 550 kg, with a daily milk yield of 20 kg 4% fat and balanced on the basis of the main nutrients in accordance with the norms. Іn the feeds, excrements, urine and milk of cows, the content of trace elements copper, zinc and manganese was determined by the standardized atomic absorption method on the spectrophotometer AAS-30 («SaglZeiss», Germany). Found a higher percentage of trace elements deposition in the body cows of feeding of chelates of copper, zinc, and manganese in the concentrations that cover their deficit in the diet in the 100% and 50% in the experimental I and II groups: Cu – 7.3% (P < 0.05) and 1.4%, Zn by 12.2% and 15.0% (P < 0.001), Mn by 13.2% (P < 0.01) and 9.0% (P < 0.05), respectively, in comparison with their sulfate salts in a 100 % dose. Based on the results of the balance study, the use in the feeding of cows during lactation of chelates of trace elements in concentrations intermediate to different experimental groups was proposed, namely – below normal their input in the form of sulfate salts on 25% for copper, 50% – zinc, and 65% – for manganese (calculated on pure element).
