Diagnosis of Infertility in Cow
Infertility is the inability of a female to conceive even after being serve by a proven male
Causes
Nutritional deficiencies
Abnormalities of reproductive organs
Metabolic function disruption
Infectious agents
Breeding history
Date of parturition
Complications and treatments
Condition of the calf
Estrus and service dates
Check for abortions
Retained fetal membranes, metritis and cystic follicles are important cause of infertility
The fetus and placenta should be refrigerated and submitted for lab diagnosis to check for infectious agents such as mycotic infections
Check for vaginal discharge
Purulent discharge are associated with metritis
Due to poor hygiene at parturition
Vaginal discharge should be clear before and during estrus cyle
Check for duration of estrus cycle
Irregular cycles indicate cystic follicles
Check for breeding efficiency
Compare heifers and cows
The conception rate between heifer that are mated naturally and conception rate of cows that are artificially inseminated
Comparison for artificial insemination based on some criterias
Time of breeding
Quality of semen
Insemination techniques
Check for the source and fertility of semen
If naturally bred, bulls should undergo fertility examination
Proper estrus detection
Breeding at the wrong time in relation to onset of standing estrus is cause of infertility
Cows should be checked regularly for standing heat
Isolate the cows that show signs of standing heat
Collection of samples
Uterine culture
Determine the presence of pathogenic organisms in the uterus and their sensitivity to the antibiotics
Especially for
Vibriosis
and
Trichomoniasis
Uterine biopsies
Histopathological examination to confirm the presence of endometrisis
Blood sample
Include hemoglobin, protein,calcium,phosphorus, vitamin A and serological examination
Phosphorus deficiency can cause infertility
