Pesticide-contaminated manure applied to land has been used in filtration by few studies. Notably, manure contaminated with vanisulfane and its metabolites mostly appeared as bound residues shortly after introduction, and BR release was discovered at 35 d. This research provides valuable insight into pesticide contamination from manure, as well as emphasizes the importance of considering pesticide metabolites when assessing environmental risks.

B12 levels and intermediates of the methionine-folate cycle in circulation were determined by this research in beef heifers fed rumen protected methionine and choline. TMR, MET CHOL, 10 mg folate, and 80 mg folate at d 0 and 7 in the estrous cycle, 0XNEG, MET CHOL, b12, xy, TMR, MET CHOL, 0. 00 percent of the diet, 8. 0 mg folate, and 80 mg folate at d 0 and 7. 1X: tt; TMR, MET, CHOL, 10 mg B12, and 80 mg folate at d t e, t x, t a t e t ot 0 and 7X, m t e g, t a t 0 and 7X t sa, g, and 7x t e t a chon protected het, and 0 and 7 0 and 7XNEG, X, x taline, e H12, t, a tail, taline injectionsax, 7X; Serum folate concentrations were higher for the 2X treatment at d 5, 7, and 9 of the cycle, compared to all other medications. Intermediates of the hepatic folate cycle intermediates were always higher in the 2X treatment relative to the 0XNEG and 0XPOS heifers. Compared to the 0XNEG, 0XPOS, and 2X heifers, the hepatic transcript abundance of MAT2A and MAT2B was reduced in the 0. 5X heifers. To maintain elevated serum concentrations of B12 and folate, beef heifers fed rumen protected methionine and choline are shown that increased serum concentrations of B12 and folate are required. These results show that beef heifers fed rumen shielded methionine and choline are required.
