“…In one study, Se was supplemented to grass as a fertilizer [25]; in another study, Se was provided to animals orally [76]; and in the rest of the studies, Se was mixed with the diet. As shown in Table 1, different dietary Se species increased total VFA concentrations and molar proportions of propionate in the rumen fluid of dairy cows [24,26,69,77], Holstein bulls [78,79], Holstein dairy calves [80], goats [81,82], sheep [25,73,75,83], and lambs [84,85]. Lambs and sheep fed organic or inorganic Se diet exhibited an increase in the production of ruminal acetate, iso-butyrate, and iso-valerate compared with the control group [83][84][85].…”

“…Moreover, the molar proportion of acetate was lower in dairy bulls fed sodium selenite and coated sodium selenite compared with animals receiving the basal diet [79]. All types of dietary Se decreased acetate to propionate (A to P) ratio in the rumen fluid of different ruminants [24][25][26]69,73,75,[77][78][79][80]86]. In few instances, inorganic and organic Se at different doses had no effects on ruminal total VFA [86,87], composition of VFA [86][87][88][89], and A to P ratio [84,[86][87][88].…”

“…Se supplements decreased rumen pH and NH 3 -N concentration in dairy cows [24,26,69,77], steers [78,79,86], Holstein dairy calves [80], goats [81,82], sheep [73,75,83], and lambs [85]. On the other hand, ruminal NH 3 -N concentrations in the rumen of rams receiving the medium level of Se yeast were higher than those in high and low Se yeast groups and the control group [25].…”

Effects of Selenium Supplementation on Rumen Microbiota, Rumen Fermentation, and Apparent Nutrient Digestibility of Ruminant Animals: A Review

Enzymes excreted by rumen microbiome facilitate the conversion of ingested plant materials into major nutrients (e.g., volatile fatty acids (VFA) and microbial proteins) required for animal growth. Diet, animal age, and health affect the structure of the rumen microbial community. Pathogenic organisms in the rumen negatively affect fermentation processes in favor of energy loss and animal deprivation of nutrients in ingested feed. Drawing from the ban on antibiotic use during the last decade, the livestock industry has been focused on increasing rumen microbial nutrient supply to ruminants through the use of natural supplements that are capable of promoting the activity of beneficial rumen microflora. Selenium (Se) is a trace mineral commonly used as a supplement to regulate animal metabolism. However, a clear understanding of its effects on rumen microbial composition and rumen fermentation is not available. This review summarized the available literature for the effects of Se on specific rumen microorganisms along with consequences for rumen fermentation and digestibility. Some positive effects on total VFA, the molar proportion of propionate, acetate to propionate ratio, ruminal NH3-N, pH, enzymatic activity, ruminal microbiome composition, and digestibility were recorded. Because Se nanoparticles (SeNPs) were more effective than other forms of Se, more studies are needed to compare the effectiveness of synthetic SeNPs and lactic acid bacteria enriched with sodium selenite as a biological source of SeNPs and probiotics. Future studies also need to evaluate the effect of dietary Se on methane emissions.

The present study is carried out to study the effect of Folic Acid (FA) by injection and supplementary on animal body weight gain, Testes volume before slaughtering, Testes volume after slaughtering, Testosterone concentration in blood, and FA concentration in blood. Twenty-five (25) Karadi male lambs five months aged and the average weight was 24.54 ±1.92 kg were used in this experiment. The animals weighed after three months of treatment to get animal increased live weight, The testes measured after one, two, and three months of treatment to calculate testes volume, testosterone, and FA concentration level in the blood were taken after one, two, and three months of treatment. The present study demonstrated that animal body weight, animal body weight gain, and total body weight gain significantly not increased (p>0.05). Testicular length, and testicular circumference not increased (p>0.05) after 1st, 2nd, and 3rd months after treatment, and after slaughtering. However, testicular high increased (p<0.05) after each month of treatment and slaughtering. Testosterone concentration in the blood significantly not different (p>0.05) reported between treatments after the 1st, 2nd, and 3rd months of treatment. FA concentration in the blood significantly increased (p<0.05) when used 3 and 6 mg FA by injection compared to control after 1st and 2nd months of treatment. However, blood FA concentration increased (p<0.05) when used FA 6mg/ml as an injection after the 2nd month of treatment compared to control. While using FA by supplementation and injection significantly (p>0.05) on the diameter and circumference of seminiferous tubules, germ cells thickness, and lumen diameters.
