You could be a touch more specific here. We don't know whether 4-6-09 is March 6, 2009, or June 4, 2009. Either way, if the cow was bred on June 4, she would be calving on March 16, 2010. But, if she was bred on March 6, then she'd be calving on Decemeber 16, 2009.
No. A Hereford cow will only give birth to a Hereford-Limousin cross calf if bred to a Limousin bull. Only a Limousin cow can give birth to a Limousin calf--IF she's bred to a Limousin bull. Just like a Hereford cow can only give birth to a Hereford calf if bred to a Hereford bull. Otherwise, she too (referring to the Limousin cow) can give birth to Hereford-Limousin-cross calf if bred to a Hereford bull.
9 weeks
You breed to pure bred horses of the same breed, for example: breed 2 pure bred Mustangs. (it doesn't have to be Mustangs) and the baby will be a pure bred Mustang(:
That really depends on when she was bred. The average gestation period of a cow (or heifer) is around 285 days. Thus, if a heifer was bred when she was 15 months old, then she would likely give birth by the time she is 24 months of age. If she was bred when she was 18 or 20 months old, then she would calve out when she's 27 to 29 months of age.
VERY very rarly... maybe 1 out of 1,000 will give birth if bred.
Better than 90%. Honestly.
Any time of the year, or any month, depending on when the cow was bred.
Usually about 4 days but can be as long as 6 months.

Cattle can give birth anytime during the year, however, beef cattle are usually bred to calve in January. Dairy cattle are bred to calve at anytime throughout the year. Heifers (both dairy and beef) are bred to have their first calf when they reach 2 years of age. They are pregnant for 9 months and are re-bred usually, 4 to 5 months or longer after the last parturition date.
Yes, girls do give birth, or the population of the Earth would fall dramatically.
No. Why would they?
