Rachel Alexandra was showing ''improved attitude'' on Friday but remained in serious condition.
Veterinarians at Rood and Riddle Equine Hospital were pleased with the mare's progress following surgery Wednesday to repair a section of her small colon. The 2009 Horse of the Year developed complications related to the birth of her 140-pound filly by Bernardini on Tuesday.
Rachel Alexandra's vital signs remain normal and she was brighter and more alert.
Owner Barbara Banke says ''she looks better today.'' Banke says her horse is a determined fighter, adding ''It makes me feel better that she was happy to have a mint. I want to thank all her fans for their incredible devotion to Rachel. Your thoughts mean so much right now.''
Rachel Alexandra's foal continues to do well at Stonestreet Farm.
