Little is known about the effects of the high dose and types of manganese supplements on rumen environment at manganese intake level close above the limit of 150 mg/kg of dry feed matter. The effects of high dose of two manganese supplements (organic and inorganic) on rumen microbial ecosystem after four months of treatment of 18 lambs divided into three treatment groups were studied. We examin...

Two studies were conducted to determine the effects of eliminating the supplemental vitamin and minerals during the last 30 d of finishing on pig performance. The first study was conducted in a controlled university environment and the second under field conditions. Deletion of vitamin and mineral supplements for the last 30 d of finishing had no effects on pig performance or general health of ...

Soybean meal (SBM) is widely used in shrimp feed agro-industry as a fish (FM) replacement. However, high levels of SBM may compromise animal health result nutrient imbalance. This study aimed to investigate the effects enzyme combination (a mixture 6-phytase, serine protease, and endo-1,3(4)-β-glucanase) functional immunostimulant brewer's yeast, nucleotides, vitamin C, E) improving overall Pac...

Antibiotic feed supplements have been implicated in the rise of multidrug-resistant bacteria. An alternative to antibiotics is probiotics. Here, we report the genome sequences of two Bacillus and one Solibacillus species, all spore-forming, Gram-positive bacteria, isolated from the feces organically raised chicken feces, with potential to serve as probiotics.

BACKGROUND Recombinant monoclonal antibodies have been marketed in last three decades as the major therapeutic proteins against different cancers. However choosing a proper medium and supplements to reach the high expression is a challenging step. Despite of commercial serum free and chemically defined media, there are still numerous researches seeking the optimum media to gain higher expressio...

Mineral supplements to the cowherd during summer grazing are an important management practice to improve cow and calf health and performance. Mineral supplements provided to the cowherd can contain Aureomycin for the control of active anaplasmosis infections or Rumensin to improve feed efficiency and coccidiosis control. This study compared the effects of supplying a mineral supplement containi...
