[QUOTE="TSR, post: 146142, member: 434"] I agree with Frankie on the bull selection. I might also add that if you will breed those heifers to calve at about the end of your hottest three months the calves will GENERALLY be smaller. This gets back to the previous discussion about calves being born larger in the North. The reason is basically more blood flow is to the outside of the animal (continually trying to keep cool on the hot days) therefore a smaller calf. Unlike in winter when more blood flow is directed toward the inside trying to keep warm, conserving the heat in the blood/circulatory system. More blood flow to the inside=more blood flow to the yet to be born calf, resulting in a larger calf. Also, nobody wants to pull a calf but a spreading of the pelvic area before maturity (2-3 yr old) due to a larger calf will generally mean easier births in the future. JMHO [/QUOTE]
