40. Definition of the presentation, position, and posture of the foetus in cattle. Normal and abnormal presentations in cattle. Flashcards
Normal presentation?
Presentation, position, and posture describes how the foetus lays in the pregnant uterus or within the birth canal
1.Presentation
Relation of the long axis of the foetus to that of the dam
Normal: longitudinal presentation
Longitudinal anterior presentation
Normal presentation
Abnormal presentation
Dorso-transverse presentation
Abnormal presentation
ventro -transverse presentation
abnormal presentation
Oblique ventro vertical presentation
and no pic oblique dorso vertical presentation
Differentiation of normal presentations?
(Anterior presentation)
Differentiation of Normal (longitudinal) Presentations
Anterior presentation
- Metacarpophalangeal joint (fetlock) and the carpus joint are flexed to the same direction
- Bony knob (tuber olecrani) is present at the second joint proximal to the fetlock
- In dorsal position of the foetus the palmar sides of the forelimbs are facing vertical
- Recognition of the head and neck (mouth, nose, ears, trachea, mane)
Differentation of normal presentation?
(Posterior presentation)
Posterior presentation
• Metatarsophalangeal joint (fetlock) and the first joint proximal (tarsal) to that are flexed to the opposite
direction
- Bony knob (tarsus) is present at the first joint proximal to the fetlock
- In dorsal position of the foetus the plantar sides of the hind limbs are facing dorsally
- Recognition of tail, anus, umbilical cord, testis, scrotum
Position?
Position
Relation of the vertebral column of the foetus to that of the dam
Normal: dorsal (upright) position
Posture?
Posture
Relation of the head, neck, and legs of the foetus to its trunk
Normal: a) during pregnancy: flexed
b) during parturition: extended
Predisposing factors for abnormal postures
- Premature birth
- Any type of uterine inertia
- Twins
- Reduction in the intrauterine space
Abnormal head positions?
Abnormal forelimb presentations?
Abnormal Hindlimb presentation?
Normal presentations?
Normal presentations.
• During pregnancy; longitudinal presentation (anterior or posterior)
Dorsal (upright) position (ventral in equine)
Flexed posture
• During parturition; same as above but extended posture
