Resumo: | Milk production of transgenic does was evaluated by ultrasound measurements of the mammary gland. Two Canindé goats, which were nine months of age were used in the trial, one non-transgenic or other transgenic for hG-CSF. For hormone-induced lactation, animals were given estradiol (0.25mg/kg, IM), progesterone (0.75mg/kg, IM), and prednisolone (0.4mg/kg, IM). Ultrasonographic exams were carried out during milking, using a Falcon 100 ultrasound equipment with a 5MHz convex probe and were performed by the same operator. The results were expressed as mean±standard error. The maximum greater length and shorter length of the cistern were respectively 5.14cm and 1.36cm for the transgenic animal and 7.28cm and 2.25cm for non-transgenic, which is consistent with the maximum milk volume produced. The relationship between the average area of cisterns and milk yield was expressed as a linear correlation curve, with a correlation coefficient significantly positive for both transgenic (Y=-1.1314+10.8538*x; r=0.97) and non-transgenic (Y=-21.7551+18.3634*x; r=0.97) animals. In conclusion, the ultrasound is a practice and appropriate technique to evaluate the cisterns in ruminant udders in transgenic animal.
