Effect of Dietary Moringa Seedcake, Folic ACID, and Zinc Oxide Supplementation on Reproductive Performance of Rabbits (Oryctolagus Cuniculus)
This study investigated the effects of varying dietary levels of moringa seedcake, folic acid, and zinc oxide on the reproductive performance of rabbits and found that while overall interactions were not statistically significant, specific combinations such as 25% moringa seedcake with 50 mg/kg folic acid improved litter size at birth, whereas 40 mg/kg folic acid with 150 mg/kg zinc oxide maintained performance without negative effects.

Rabbit farming offers a promising way to boost the supply of animal protein, largely because these animals reproduce quickly, grow fast, and can thrive on a wide variety of plant foods. However, the success of a rabbitry often hinges on the quality of the feed, especially during the critical periods of growth and breeding. As the cost of traditional feed ingredients rises, farmers are increasingly looking toward local, affordable alternatives that do not compromise the health of their animals. Among these alternatives is the seedcake left over after extracting oil from the moringa tree, a plant common in tropical regions known for its nutritional value. Alongside plant-based feeds, specific vitamins and minerals play a vital role in animal biology; folic acid helps build DNA and supports cell division, while zinc is essential for immune function and reproduction. The question facing researchers is whether combining these specific ingredients—moringa seedcake, folic acid, and zinc oxide—creates a diet that supports healthy rabbit reproduction or if the mix might cause unexpected problems.
To answer this, a researcher at the University of Skills Training and Entrepreneurial Development in Ghana set up a controlled experiment involving thirty rabbits. The group consisted of twenty-four female rabbits and six males, all approximately seven weeks old and weighing just under one kilogram. The females were divided into eight different groups, with each group receiving a unique diet. The scientist varied three specific components in the feed: the amount of moringa seedcake, the level of folic acid, and the amount of zinc oxide. For the seedcake, they tested two inclusion rates of twenty percent and twenty-five percent. For folic acid, they used levels of forty and fifty milligrams per kilogram of feed, and for zinc oxide, they tested one hundred and fifty and one hundred and fifty-five milligrams per kilogram. This setup allowed the researcher to see not only how each ingredient worked on its own but also how they might interact with one another. The rabbits were housed individually in clean hutches, fed twice daily, and given water freely. Once the females reached a suitable age and weight, they were mated with the males, and the researcher carefully tracked the entire reproductive cycle, from pregnancy to the survival of the young kits after weaning.
The results of the study revealed that the combination of these ingredients did not harm the rabbits' ability to reproduce, suggesting that moringa seedcake is a safe component of their diet. However, the specific amounts used did influence certain outcomes. Rabbits fed the higher level of folic acid, fifty milligrams per kilogram, experienced a slightly longer pregnancy, lasting thirty-three days. More notably, the researcher found a powerful combination when they mixed the higher level of moringa seedcake, twenty-five percent, with the higher level of folic acid. This specific pairing produced the largest number of babies at birth, with an average of roughly four kits per litter. This suggests that the protein-rich seedcake and the cell-building properties of folic acid worked together to support a larger litter.
Despite these positive signs for litter size, the study also highlighted a potential risk associated with zinc oxide. The group of rabbits that received one hundred and fifty milligrams of zinc oxide per kilogram of feed experienced the highest rate of death among the young kits before they were weaned. Furthermore, when this specific amount of zinc was combined with the lower level of moringa seedcake, it led to the highest rate of death among the kits after they were weaned. These findings indicate that while the plant-based feed and the vitamin were beneficial, the mineral supplement requires careful handling. The researcher concluded that a diet containing twenty-five percent moringa seedcake and fifty milligrams of folic acid could be used to increase the number of babies born without hurting the mother's health. However, they advised caution with zinc oxide levels, noting that the specific dosage of one hundred and fifty milligrams per kilogram might increase the risk of losing young rabbits during the critical early weeks of life. Ultimately, the study provides a clear path for farmers to use local resources effectively while avoiding specific nutritional pitfalls that could endanger the next generation of rabbits.
