Sheep mating and early pregnancy
- Good ewe Body Condition Score during mating means good ovulation rate and high lambing percentage.
- Increasing live weight during the mating period will help to improve lambing percentage.
- Minimise stress during mating - early pregnancy to avoid upsetting oestrus and embryo death.
- Good feeding in early pregnancy is important for early placental development, which in turn boosts lamb birth weight and hence survival, especially of multiples.
- Intake: Ewes need 1.0 to 1.5kg of average to good quality dry matter per day to hold body condition score during mating and early pregnancy.
- Ewes must be removed from pastures containing toxins like zearalenone or phytoestrogens (NUTRIMIX BLOCK contains mycotoxin binders to suppress the negative effect of toxins).
- Grass: Recovering pasture for lambing season has to be a priority. Try minimising the risk of heavy covers and grassing wastage/land damage.
Toxins and fertility
The toxin zearalenone from pasture fungus can reduce ewe fertility and fecundity. Phyto-oestrogens produced by plants such as red clover, subterranean clover and Lucerne can decrease ovulation rate by up to 30%. High ryegrass endophyte pastures can suppress lambing percentage so should not be used around mating time. NUTRIMIX sheep products contain an effective combination of mycotoxin binders.
