Etiopathogenesis of Calcium–Phosphorus Metabolism in Rabbits

/in /by

In this article clinical signs, hematological indicators and photo morphological changes in bones of the etiopathogenesis of calcium–phosphorus metabolism in rabbits are described. Low–nutrition, poor–quality feeding of mother rabbits during the estrus period means that the needs of the mother rabbits’ body for vitamins and macro–microelements are not fully met. Disorders of calcium and phosphorus metabolism in rabbits are on average 53,3% during the gestation period and on average 73,3% during the postpartum period. It is accompanied by symptoms such as a decrease in response to external influences, swelling of the skin, a decrease in gloss, strong whitening of the mucous membranes, a decrease in body weight, accompanied by symptoms such as a change in appetite.

The Concentrations of Cholesterol and Reproduction Hormones in Serum of Rabbits Doe That Consumed Moringa oleifera Leaf Extracts

/in /by

This study was conducted to examine the effect of various kinds of Moringa leaf extracts on cholesterol, estradiol, FSH, LH levels and litter size in rabbit does. The extracts used were hexane fraction extract (HeEF), ethanol fraction extract (EtEF) and ethanol rough extract (EtCE) from moringa leaf flour. Seven treatments were administered including extracts in pellets at a dose of 0, 0.13% HeEF, 0.26% HeEF, 0.37 EtEF, 0.74% EtEF, 0.54% EtCE and 1.08% EtCE. Each treatment was reduplicated on 4 rabbits. Cholesterol levels, estradiol, LH and FSH blood serum, mating readiness and litter size were measured, which results showed that the treatment significantly (P <5%) lowered the cholesterol level and increased the estradiol level in blood serum. On the other hand, the treatment had no significant effect on FSH, LH and litter size levels except at LH levels 2 hours after mating.
