Abstract (English)

Nutraceuticals are food components that offer health benefits; those found in plant-based supplements are believed to influence the development of avian embryos, improving growth, immunological response, and survival rates, promoting the quality of the chick before hatching. Due to its potential health advantages, Moringa oleifera, also known as malunggay in the Philippines, is a prospective option. The objective of the study was to screen the effects of Moringa oleifera (Malunggay) on the growth and development of chick embryos. This was determined through the injection of two doses of Moringa oleifera, 500 μg/egg and 1,000 μg/egg, to 4-day-old chick embryos followed by morphometric analysis using the following parameters (in mm): (1) body weight (in gms), (2) crown-to-rump length, (3) beak length, (4) neck length, (5) wing length, (6) thigh length, (7) drumstick length, (8) shank length, and (9) third toe length. The results of the study showed that the gross weight and morphometric measurements of the treatment group with 500 μg/egg of the malunggay powdered leaves were significantly lower than the control groups. The results of the treatment group with 1,000 μg/egg of the malunggay powdered leaves, likewise, were significantly lower to the control groups. However, there were no significant differences between the two treatment groups. Both doses have seemingly similar effects on the growth and development of the chick embryo, resulting to smaller morphometric measurements. Moringa oleifera, particularly the leaves, apparently contain high and varied phytochemical components. Certain studies reported bioactives at higher concentration have anti-angiogenic effects while others with anti-nutritional effects. The inhibition of blood vessel formation may contribute to lack of oxygen and nutrients and eventually affect embryonic growth and development. While the results of the present study at these doses may have suppressed the growth of the embryo the basic developmental pathways towards structural formation were not severely disrupted to the extent of causing malformations.
