چکیده
This experiment evaluated the effect of feeding dairy cows with cottonseeds containing BollGard r (Cry1Ac) and BollGard r II (Cry1Ac and Cry2Ab), Roundup Ready r (CP4 EPSPS) and control non-transgenic cottonseed on dry matter intake, milk yield and milk composition. Twelve lactating multiparous Argentinean Holstein cows weighing 570 kg (BW) were used in a 4x4 Latin square design, with 3 squares each containing 4 cows, four 4-week periods and four treatments. The treatments were control cottonseed non-genetically modified (DP50), BollGard r
