However, in Brazil, there is little information about foal development. For this reason, this study has used data on foals from seven different farms in Pernambuco, Northeast Brazil, where horses have a major economic importance. The aim of this study was to compare foal’s development from four breeds and to develop a regression formula in order to estimate such development. It was used data from 210 suckling foals (Arabians n = 18, Campolina n = 86, Mangalarga Marchador n = 42 and Quarter Horses n = 64), raised in similar management practices. Their height at withers, heart girth, and cannon bone girth were measured monthly from birth to weaning. Data we reanalyzed by ANOVA and Tukey Test, with P established in 5%. The highest mean of height at withers was observed in the Arabian foals, and it was similar to Campolina and Mangalarga Marchador foals. The last breed presented a higher percentage of gain in height (~36%) and higher heart girth. On the other hand, Campolina foals had the highest mean of cannon bone girth. There was a significant interaction between breed and development phase in heart and cannon bone girths. All regression for mulas obtained from this data was very significant, and it was showed that they can predict height at withers in the four breeds studied. Heart and cannon bone girths showed medium value of R2 and large significance. It is important to highlight that fetal programing produces significant impact on foal development, even after weaning. So, this study would have observed some more changes if its scope had been extended beyond this phase.展开更多

Only foals with CJVDs greater than 5° were included in the study. Foals were assigned to 3 treatment groups based on their degree of CJVD measured during the initial evaluation: valgus deformity (VD) of 5° to 8.9° (Group 1), VD of 9° to 11.9° (Group 2) and VD greater than or equal to 12° (Group 3). ESWT was applied on the convex side of the angular deformity immediately following the initial radiographic evaluation. Foals were subsequently evaluated clinically and radiologically followed by treatment every 10 days until resolution of the VD, with resolution defined as a deviation less than 5 degrees. Each treatment group received specific exercise, hoof trimming and hoof/shoe extension recommendations. Sixty-four (64) foals were included in the study;ages ranged from 8 to 60 days old at inclusion in the study with a mean age of 26.7 days. Of the 28 foals included in Group 1, 10 had bilateral CJVD. There were 21 in Group 2, and 15 in Group 3. Treatment success was defined as a VD angle less than 5°, and was reached in all foals in Groups 1 and 2. Five (5) foals in Group 3 completed the study with a VD angle of 5° to 6.7° at the last radiographic assessment. No major complications were observed during the study. In conclusion, ESWT in conjunction with controlled exercise, hoof trimming and hoof/shoe extensions corrected severe CJVDs in young foals. The use of ESWT eliminates possible negative side effects of general anesthesia and surgical techniques to treat VDs. Future studies should include a control population, more severe cases, other types of angular limb deformities, and older foals.展开更多
