Effects of Sodium Selenite, L-Selenomethionine, and Selenium Nanoparticles During Late Pregnancy on Selenium, Zinc, Copper, and Iron Concentrations in Khalkhali Goats and Their Kids.

The objective of this study was to evaluate the effect of organic, inorganic, and selenium nanoparticle supplements at the final stage of pregnancy on selenium, zinc, copper, and iron concentrations of goats and placental, colostrum, and milk transfer of these trace minerals from goats to their kids. Forty pregnant Khalkhali goats (30 ± 5 kg) were randomly allocated to four treatments including (1) no supplement (control), 0.6 mg Se head day of selenomethionine (SM), 0.

Susceptibility of ruminal bacteria isolated from large and small ruminant to multiple conventional antibiotics.

The pivotal aim of the present context was to isolate diversified group of bacteria from the ruminants and to evaluate their antibiogram pattern against 22 antibiotics of 14 different classes. The bacterial isolates from small and large ruminant (sheep, cattle and calves) were isolated from the rumen based on various colonies morphology, and subjected for preliminary antibiotics susceptibility assay using disc diffusion method. The most sensitive isolates (based on zone of inhibition) were selected for determining the minimum inhibitory concentration (MIC) of each antibiotic ranging from 1 to 256 μg/mL.

Antibacterial activities of tannic acid against isolated ruminal bacteria from sheep.

This present study was conducted to evaluate the antimicrobial effects of tannic acid (TA) against isolated ruminal bacteria from adult sheep. Rumen samples were collected from two (2) adults sheep, and a total of nine (9) ruminal bacteria were isolated from the sample. The sensitivity of the ruminal bacteria isolates to 0.
