“…In our study, soya lecithin induced periovarian adipocyte hypertrophy, increased the level of unsaturated fatty acids particularly the MUFA suggesting a possible positive role of lysolecithin on reproductive performance of rabbit does. This is also supported by the observations of other researchers that the increased MUFA in the blood of female rabbits before mating increased the ovulation rate and number of offspring (Hadjadj et al, 2021;Mattioli et al, 2019). Soya lecithin increased blood glucose levels when fed to rabbits (Attia et al, 2018), helping to explain the observed adipocyte hypertrophy in periovarian fat in our study.…”

This study aimed at investigating the effect of hydrolyzed soya lecithin; also called lysolecithin or lysophosphatidylcholine, on growth performance, caecal microbiota and fat depots in pre‐breeding primiparous rabbits does. For this, 60 V‐Line primiparous rabbits does (5–6 months) were used in a 30‐day experiment. Does were allotted into three iso‐nitrogenous iso‐caloric dietary treatments (n = 20/group) as follows: (1) CON received 0% soya lecithin, (2) LECL group was fed a basal diet supplemented with 0.5% soya lecithin and (3) LECH group was fed a basal diet supplemented with 1% soya lecithin. Growth performance indices were measured, caecum samples were collected for measurement of specific bacteria via qPCR, and several fat depots including periovarian fat were sampled for adipocyte morphometry and fatty acid profiling. Statistical analysis was performed using GLM procedures of SAS v9.4. Soya lecithin increased feed intake (p < 0.05). The abundance of caecal Bifidobacteria species, Ruminococcus species and phylum Butryvibrio‐specific genes increased (p < 0.05) in rabbits receiving soya lecithin in their diet, soya lecithin increased the level of polyunsaturated fatty acids in subcutaneous and perirenal fat (p < 0.05) and increased the level of monounsaturated fatty acids in periovarian fat (p < 0.05); additionally, the adipocyte area increased in periovarian and perirenal fat (p < 0.05). In conclusion, soya lecithin at a dose of 0.5% increased feed intake and energy storage in adipocytes and improved the fatty acid profile of periovarian fat.

“…Marounek et al [ 42 ] reported that with increasing levels of dietary supplementation of unsaturated acid (CLA) to rabbits, the concentration of CLA in tissue lipids increased. Hadjadj et al [ 43 ] noted correlations between blood fatty acid levels and ovulation rate and embryonic development. Mattioli et al [ 10 ] reported that enrichment of the diet with n-3 fatty acids can be considered a good strategy to improve reproductive performance in rabbits.…”

The composition of the diet, including the amount and type of lipid supplements, influences the products formed in the digestive tract, their levels in the blood and their deposition in the tissues. One example of a plant rich in polyunsaturated fatty acids is flax (Linum usitatissimum). The aim of the presented work was to evaluate the effect of the linseed oil ethyl esters additive and environmental conditions on the selected rabbit blood parameters. The study included two types of animal maintenance (laboratory conditions and external conditions) and two seasons (summer and winter), a total of four study stages. At each stage, a control group and an experimental group were specified. The feed supplement in the form of esterified linseed oil was administered to the experimental animals for two months. The blood samples were collected at the beginning of the experiment, as well as at the end of treatment. Moreover, blood samples were collected also after two months from the end of the experiment. During the experiment, morphological and biochemical parameters of the rabbits’ blood were examined. The results of the content of fatty acids were determined in the erythrocytes and serum blood samples and grouped into saturated and unsaturated fatty acids, especially omega-3 and omega-6 fatty acids. In an internal study, the influence of housing conditions and season on selected morphological and biochemical parameters of rabbit blood was confirmed. Furthermore, expected beneficial changes in the fatty acid profile in erythrocytes and blood serum were observed as a result of supplementation. A significant increase in omega-3 fatty acids was noted as well as a substantial decrease in the ratio of omega-6 to omega-3 fatty acids (p < 0.01). Most importantly, the linseed oil ethyl ester supplement used did not adversely affect the health of the rabbits, as evidenced by biochemical and blood morphological indices remaining within, known so far, reference limits or showing only slight fluctuations (p > 0.05). However, the obtained results extend the database of hematological blood parameters in rabbits, thus, contributing to improvements in laboratory diagnostics for fur animals.

“…In mammals, fatty acids (FAs) have a variety of essential biological roles and are considered one of the functional nutrients and chemicals. Triglycerides, for example, are employed as precursors for the production of vital energyproducing metabolites [13] and oocytes and embryos use it as an energy substrate for differentiation, development, and immune system activity [14]. FAs serve as useful chemicals for a variety of reproductive processes.…”

Improvement of reproductive performance is an honorable goal and is closely associated with increasing productivity. Therefore, as the reproductive efficiency improves, the herd net return and national income increase. The high cost of animal forage especially in dry or semi-arid countries, is a main limitation to animal production which is raised under extensive systems. Hence, utilization of alternative feed resources may be a reasonable and appropriate approach in low-input systems. Moringa Oleifera is a natural plant referred to as a nutrient, which contains substances that might have a favorable influence on animal reproduction and production. Leafy Moringa is considered a virtuous origin of proteins that are very consumable. Moreover, they are rich in Vitamin C, Vitamin A, iron, and Calcium which are necessary for the growth of livestock animals. Moreover, they include the percentage of fatty acid which is greater as compared to any woody plant fodder. Principally, almost all of the fatty acids present in Moringa are unsaturated fatty acids which are highly susceptible. Nowadays, nano-encapsulation technology is considered a promising strategy for drug delivery and is efficient in preserving bioactive components in products rich in nutrients. So that this review affords a collection of significant data and enlightens the information on the development of Moringa Oleifera Free or its nano-encapsulated form in amelioration of animal and poultry reproduction and production performance.
