Main causes for infertility:
Stray voltage
Alkaline water (pH 8.2+)
Contaminated water.
High iron water.
Continuous use of iodine, which causes small ovaries, or cystic ovaries.
Retained placenta causing metritis
Demineralization (high producing cows)
Leucosis, neospora, I.B.R. etc.
Inadequate drainage (excess of fermentable soluble nitrogen at the beginning of lactation)
Rumen acidosis
Deficiency in long structural fibres = dry hay.

Treatment

Fertility, being a luxury function for a cow, can be affected by various factors.

Silent heat or sub-oestrus

Observation

Causes:
Hypoglycaemia during peak lactation compensated by excessive weight loss, de-mineralization, especially in winter. Metabolic Type no 3 with deficiency in rapidly digested carbohydrates. Metabolic Type no 7, deficiency in soluble nitrogen during peak lactation.

Treatment

Protocol:
A) First identify and correct causes: Acidify the pH if the water is too alkaline. If the ovaries are small, avoid using iodine teat dip. Labo Solidago has many possible protocols depending on the specific issue for example: LEUCOSOL for leucosis. We can help you with all kinds of problems such as Neospora, please ask for our protocols.

Drain if necessary with LIVERSOL and DRAINSOL.
For rumen instability: MOD6SOL.
For acidosis: MOD4SOL.
For demineralization: MINSOL and MOD2SOL.
For true hypoglycaemia (anoestrus): MOD5SOL

Specific Protocol:
B) Silent heat and anoestrus: HEATSOL twice a day for 3 days, then twice a week until in heat. (Also correct the cause.)

C) If there is excessive iodine, small ovaries or luteinic cysts, instead of HEATSOL, give CYCLESOL twice a day for 3 days, then twice a week until in heat. To increase the odds for pregnancy, give LIVERSOL, twice, MINSOL and SEPTISOL just before and after breeding, then HEATSOL during breeding. This is valid in the absence of uterine infection or cloudy discharge; otherwise this infection must first be treated with METSOL and SEPTISOL, if the discharge is white, use METSOL and SEPTISOL once a day, every 3 days, for 1 to 3 weeks.

Anoestrus

Observation

Specific causes: True hypoglycaemia during peak lactation, with rumen instability. Metabolic Type no 4, general energy deficiency. MOD5SOL to stimulate pancreas.

Treatment

See the Silent Heat treatement

Cystic ovaries

Observation

Cysts on the ovaries, thick uterus, irregular heats, nymphomania or aggressiveness.

Cause:
Sycotic constitution, retention of toxins, rapid weight gain (see MOD1SOL), excess of fast sugars (metabolic Type no 1, prone to swelling), excess of iodine (teat dip).

Treatment

Give CYSTSOL twice a day for 3 days, then HEATSOL, twice a day for 3 days, then twice a week until in heat.

Luteinic cyst

Observation

Uterine tubes, ovaries and even uterus full of pus, persistency of the yellow mass, sometimes abdominal pain, infertility. Cause: A side effect of artificial cycling, overloaded liver and sycotic constitution with weight gain, slow thyroid (see MOD1SOL)

Treatment

CYCLESOL in the morning and MOD1SOL in the evening, during 5 days, then twice a week, until in heat
