“…However, Machlin et al (1962) found that the addition of 7% of LA to the diet of laying hens resulted in lower fertility than the diet containing only .7% of LA. Likewise, no report exists on the effectiveness of LN on reproduction traits in quail.…”

An experiment was conducted to evaluate the effects of dietary corn oil (CO) and commercial free fatty acids on the fatty acid composition of blood plasma and egg yolk lipids and on the reproductive performance of Japanese quail. When quail were fed a semi-purified low-fat basal mix, the substitution of 3% of CO for corn starch (CS) improved egg weight (11.2 versus 10.8 g), reduced late embryonic mortality (16.7 versus 28.4%), and improved hatchability (75.7 versus 64.1%). Diets in which palmitic acid or oleic acid were substituted on a weight basis for 3% of CS performed as well as those in which CO was used. When linoleic acid replaced 3% of CS, late embryonic mortality was reduced (13.7 versus 28.4%) and hatchability was improved (80.1 versus 64.1%), but fertility was depressed (85.8 versus 93.6%). The substitution of linolenic acid for 3% of CS depressed feed consumption, body weight, and egg weight relative to the low-fat CS diet and did not improve the low 18-day embryonic livability and low hatchability. The fatty acid compositions of plasma and yolk were influenced by the lipid composition of the diets. Quail fed 3% of CO deposited more linoleic acid in the egg than those fed 3% of linoleic acid (15.2 versus 11.7%). Thus, quail fed a simplified basal breeder diet containing .6% of linoleic acid showed decreased embryonic livability and hatchability and these parameters achieved normal levels in response to the substitution of 3% of either CO, palmitic acid, oleic acid, or linoleic acid for CS.

“…Linoleic acid is one of the essential polyunsaturated fatty acids that cannot be produced de novo in vertebrates. If an animal diet is rich in any polyunsaturated fatty acids, the addition of an antioxidant is required in order to avoid peroxidation of the fatty acids [23]. Arscott and colleagues [24] fed adult male White Leghorn (WL) chickens with diets containing high levels of linoleic acid (7.3%) and an either low (4.3 mg/kg feed) or high (166.3 mg/kg feed) amount of vitamin E for 25 weeks.…”

“…It has been identified as an anti-sterility vitamin, and its deficiency or long-term omission in the diet causes abnormal spermatogenesis and affects the semen qualities, including sperm viability, sperm motility, and sperm capacity [5,10,12]. Earlier studies reported that testicular degeneration resulted when Rhode Island Red males were fed a vitamin E deficient diet for two years [23,24]. From the studies reviewed above, it has been understood that dietary supplementation with vitamin E protects semen quality, especially by preventing the breakdown of polyunsaturated fatty acids, which can cause oxidative damage.…”

“…The concentrations of total lipids, including the polyunsaturated fatty acids of the linoleic acid series, and of antioxidants are relatively stable in the eggs of chickens fed with a standard diet, but they are subject to alteration by major changes in dietary nutrient composition [47,48]. Similar to Arscott’s study in males [24], Machlin and colleagues [23] fed WL hens with a basal diet high in linoleic acid (7%) and low in vitamin E (20 IU/pound feed) for eight weeks. By the end of this period, egg production had decreased from 78% to 25%.…”

“…Together with the results obtained for males [24], this study suggests that vitamin E acts as an antioxidant, in that it protects female fertility by preventing the breakdown of linoleic acid, which would then lead to oxidative damage. Additionally, the study by Machlin and colleagues showed that hens fed with diets low in linoleic acid do not require additional vitamin E or antioxidants for maintenance of egg production, fertility, and hatch of fertile eggs [23]. When Yoshida and Hoshii fed WL hens with a basal diet containing 12% dilauryl succinate, which has similar effects as linoleic acid, the fertility of eggs and the hatchability of fertile eggs were observed to be low.…”

Vitamin E is found in high quantities in vegetable oils. Although vitamin E has multiple functions in humans and animals, its key function is protecting cells from oxidative damage. Since its discovery, several studies have demonstrated that vitamin E deficiency causes impaired fertility in humans and lab animals. However, the effects of vitamin E deficiency or of its supplementation on the fertility of farm animals, particularly on poultry, are less well studied. Therefore, a comprehensive review of the effects of dietary vitamin E on the fertility of poultry species is needed in order to understand the beneficial role of vitamin E in the maintenance of sperm and egg qualities. Based on the observations reviewed here, we found that a moderate amount of vitamin E in poultry diet significantly protects semen/sperm qualities in male birds and egg qualities in female birds via decreasing the lipid peroxidation in semen/sperms and eggs. This review provides an overall understanding of the effects of dietary vitamin E on fertility functions in poultry species.

The biological consequences of feeding polyunsaturated fatty acids to antioxidant‐deficient animals

The addition of polyunsaturated fatty acids (PUFA) to diets deficient in vitamin E and other effective antioxidants results in a variety of symptoms in animals. For example, the feeding of such diets to rats results in muscular dystrophy, testis degeneration, dental depigmentation, brown discoloration of the fat and and uterus and creatinuria Similar diets fed to rabbits and ruminants results in muscular dystrophy. In chickens the symptoms observed are encephalomalacia, lowered egg production, and poor hatchability. The addition of PUFA to diets is known to result in the destruction of vitamin E in the diet or in the tissues of animals as a result of free radicals produced during the autooxidation of the PUFA. However, in several studies, this possible explanation for the development of vitamin E deficiency symptoms has been made untenable. In such studies the more likely explanation for development of symptoms is thein vivo peroxidation of PUFA in the tissues of animals following incorporation of large amounts of PUFA in lipid structures and depletion from the tissues of vitamin E and other biologically effective antioxidants.
