There was positive correlation (r2 = 0.5974; p less then 0.01) between MeHg and CN in River Aprepre. The water-soluble fraction of Hg in sediment from both rivers was  less then 1% of THg. Hg in sediments from River Aprepre were generally more soluble than that from River Ankobra, indicating that Hg in sediments from River Aprepre were potentially more bioavailable for methylation. Accordingly, the presence of CN in Hg-dominated river sediments potentially influences and enhances the solubility and mobility of Hg, resulting in increased Hg methylation rates.To evaluate the optimum age of straw addition to starter diet on growth of calves, 40 Holstein calves (36.7 ± 4.96 kg) were assigned at 3 days of age to 1 of 4 treatments in a completely randomized design. Dietary treatments (% of dry matter) were as follows control starter without any wheat straw (WS) inclusion until weaning (WS0); 90% calf starter concentrate (CSC) + 10% chopped WS offered from day 3 of age to weaning (WS3); 90% CSC + 10% chopped WS offered from day 21 of age to weaning (WS21); and 90% CSC + 10% chopped WS offered from day 40 of age to weaning (WS40). After weaning at 60 days of age, all calves received the same diet until finished at day 72 of age. Solid feed intake was affected by treatments whereby either pre- or post-weaning starter intake was greater for calves fed WS (P less then 0.01), and WS3 fed calves had lower starter intake compared to WS21 and WS40 (P less then 0.01). Weaning weight was the greatest for WS21 treatment compared to other groups (P less then 0.01), although all forage fed calves were heavier than WS0 (P less then 0.01). Accordingly, average daily gain also showed a similar pattern (P less then 0.01). Without any difference at post-weaning, pre-weaning glucose was lowest i
