In sheep and goats the principal benefits of the use of the technique include the ability to relate feed inputs in late pregnancy to foetal numbers, thus improving the efficiency of use of feedstuffs. Feeding in relation to foetal numbers also o

Ultrasonic Characteristics of Physiological Structures on Bovine Ovaries,of functional corpora lutea, follicular and luteinized cysts, haematomas in the ovaries, ovarian responses to hormonal treatment (1,25) and abnormalities in the ovarian region. Other applications of ultrasonography in cows besides the study of ovarian structures include early pregnancy diagnosis (1,
