This study was conducted to determine if diets supplemented with turmeric powder (Curcuma longa) affected the reversible sterilization of Pseudotropheus socolofi. Three experimental diets were formulated to contain 0%, 10%, and 14% turmeric powder. The fish (mean weight 13 g) were randomly divided into groups consisting of 1 male and 4 females for each aquarium and were kept together for 137 days. The control group was fed a diet without turmeric, while the others were fed diets with turmeric for the first 75 days. All groups were then fed the control diet from day 75 to 137. The results showed that turmeric powder supplementation did not affect growth performance (p ˃ 0.05). A histopathological examination of the ovaries, performed on two samples on days 75 and 137, revealed that high doses of turmeric decreased number of ovulated vitellogenic follicles and ovarian activity. Moreover, immature follicle density was excessive in groups fed turmeric powder. However, the number of ovulated vitellogenic follicles increased in groups fed diets containing 10% and 14% turmeric after feeding them with the turmeric-free control diet from day 75 to 137. In conclusion, the study revealed that supplementing diets with high ratios of turmeric can influence ovarian activity; however, these effects can be reversed by ceasing supplementation.

通过向雌性假单胞菌socolofi的饮食中补充姜黄粉（Curcuma longa）可逆灭菌。

进行该研究以确定补充姜黄粉（长姜黄）的饮食是否影响了Pseudotropheus socolofi的可逆灭菌。配制了三种实验饮食，分别含有0％，10％和14％姜黄粉。将鱼（平均重量13 g）随机分为一组，每只水族由1只雄性和4只雌性组成，并一起饲养137天。对照组在头75天内饲喂无姜黄的饮食，而其他人则饲喂姜黄的饮食。然后从第75天到137天，给所有组喂饲对照饮食。结果表明，补充姜黄粉不会影响生长性能（p˃0.05）。在第75天和第137天对两个样本进行卵巢组织病理学检查，揭示高剂量的姜黄减少了排卵的卵黄形成卵泡的数量和卵巢活性。此外，姜黄粉喂养组的卵泡密度未成熟。但是，从第75天到第137天，在饲喂含10％和14％姜黄的饮食的人群中排卵的卵黄卵泡的数量增加了。最后，研究表明，补充高比例姜黄的饮食会影响卵巢活动；但是，这些影响可以通过停止补充而逆转。从第75天到第137天，在饲喂含10％和14％姜黄的饮食的人群中排卵的卵黄卵泡的数量增加了。最后，研究表明，补充高比例的姜黄的饮食可以影响卵巢活动 但是，这些影响可以通过停止补充而逆转。从第75天到第137天，在饲喂含10％和14％姜黄的饮食的人群中排卵的卵黄卵泡的数量增加了。最后，研究表明，补充高比例的姜黄的饮食可以影响卵巢活动 但是，这些影响可以通过停止补充而逆转。
