The Dean of the College of Agriculture at the University of Diyala, Professor Dr. Raed Ibrahim Khalil, chaired the committee for the defense of a master’s thesis held at our college. The thesis is entitled:
“The Effect of Oral Administration of the Amino Acids Methionine and Lysine on the Ovaries, Selected Hormones, and Biochemical Blood Parameters in Local Female Goats During the Summer Season.”
The study, presented by the student Mohammed Hameed Abbas, aimed to investigate the effects of the amino acids methionine and lysine, along with the summer months of July, August, and September, on the fertility of local female goats. This was achieved by examining the following variables:
-
Ovarian and oocyte characteristics, including: ovarian weight, length, thickness, volume, the number and diameters of mature and immature ovarian follicles, the number and diameters of oocytes.
-
Hormonal indicators, including: estrogen, progesterone, and thyroid hormones (T3 and T4).
The study arrived at several conclusions, among which were the following:
-
A significant increase in ovarian weight, length, thickness, and volume, as well as in the number and diameters of both mature and developing follicles and oocytes—reflecting a positive impact on reproductive performance both during and outside the breeding season.
-
A statistically significant elevation in the levels of estrogen, progesterone, and thyroid hormones (T3 and T4), contributing to enhanced reproductive efficiency in female goats.
-
An improvement in the biochemical properties of blood serum, along with a reduction in free radicals.
The study recommends the following:
-
The oral administration of a balanced mixture consisting of 2 grams of methionine and 2 grams of lysine per animal to enhance reproductive efficiency in female goats outside the breeding season.
-
Conducting a similar study incorporating an additional amino acid to evaluate its effect on the reproductive performance of female goats.
-
Undertaking a related study involving the oral administration of methionine and lysine to male goats during the non-breeding season to examine the impact on semen characteristics.
-
Performing a parallel study on newborn goat or sheep lambs to monitor their growth, feed conversion efficiency, and the microbial community in the rumen.
