The effect of feeding sodium aluminum silicate in the prepartum period on serum mineral concentrations in multiparous Holstein Cows
Published:January 23, 2018
Summary
Introduction • Most cows are unable to elude some level of hypocalcemia in the immediate postpartum period, with 40 to 70% of multiparous cows developing subclinical hypocalcemia (SCH; Reinhardt et al., 2011; Caixeta et al., 2015; Neves et al., 2017). • Supplementing anions in prepartum rations is a common strategy to improve blood Ca concentrations however, SCH is often not elimi...
Dear friend even without the ca fatty acids you can achieve the production and or fertility just by feed supplements which I have studied for fertility, estrous synchronization and as antimicrobial agent just a balanced Magic silver bullet a magic dust
Rudra Desai Subclinical hypocalcemia is a serious problem as more than 50-60 % of cows has been found to suffer from this disease. The methods used so far, mainly the DCAD methods as well as intensive use of calcium bolus, has not been able to eliminate this diseases. X-Zelit is a new way to attack this challenge and we are impressed that it possible to see so clear positive effect on the reproduction. After 150 days, 30 % of the control group were not pregnant whereas in the X-Zelit group only 10 % were non-pregnant. This show that low calcium at calving negatively influence the production of the animal in the whole lactation.
