[QUOTE="Pineland, post: 903364, member: 15888"] In case you are bored. [url=http://www.iowabeefcenter.org/Beef%20Cattle%20Handbook/Calving_Difficulty-1.pdf]http://www.iowabeefcenter.org/Beef%20Ca ... ulty-1.pdf[/url] To summarize. Breed of Dam Breed of dam effects on dystocia and birth weight do not follow a consistent pattern, except for the Zebu-influenced females. As the percentage of Zebu breeding increases in the dam, the birth weight and dystocia decline. Birthing assistance for F1 Brahman dams exhibit assistant rates of 1-2 percent. Uterine Environment Researchers at Marc reported that fetal growth during the last 20 percent of gestation is dramatically lower in Brahman than in Charolais cows, which explain the lower birth weights of calves from Brahman-influenced dams, as noted above. They provided evidence which suggested that this difference is due to the differences in uterine blood flow and the function of the utero-placental tissues. Research at Miles City has likewise show that diverse breeds of dams differ greatly in the growth rate of the fetuses they are carrying. [/QUOTE]
