“…In the current study, the HFD contained an increased ratio of saturated fatty acids and a decreased ratio of polyunsaturated fatty acids. This change in the composition of the dietary fats may be responsible for the observed reproductive effects, as many previous studies have reported [ 37 – 39 ].…”

IntroductionGlobally, the prevalence of overweight and obesity is increasing, predisposing females to health hazards including compromised reproductive capacity. Our objective was to investigate the effect of ad libitum, isocalorically and hypocalorically restricted high-fat diet (HFD) feeding on reproductive function in diet-induced obese female rats.Material and methodsTwenty female albino Sprague Dawley rats were used; 5 rats were kept on a standard pellet animal diet to serve as a control group (A) and 15 rats were fed a HFD for 9 weeks to induce obesity. The HFD fed animals were equally divided into three groups: an ad libitum HFD group (B), an isocalorically restricted HFD group (C), and a hypocalorically restricted HFD group (D). Estrous cyclicity, hormonal levels, ovarian histopathology and caspase-3 immunoreactivity were evaluated.ResultsThe HFD-fed rats in groups B, C and D had significant irregularity in estrous cyclicity Vs group A (p = 0.001, 0.003 and 0.034 respectively). Groups C and D had significant reduction in serum progesterone level (p = 0.006 and 0.018 Vs A). Isocaloric restriction of HFD feeding significantly increased serum LH. Groups B and C had a significant increase in caspase-3 expression in the ovary (p < 0.001).ConclusionsAd libitum HFD interfered with the normal estrous cycle and enhanced apoptosis of luteal cells in obese female rats. The HFD restriction interfered with the normal estrous cycle and caused functional insufficiency of the corpus luteum in obese female rats. These results suggest that HFD feeding determinately affects female reproductive function independently of caloric intake.

“…It is well-known that PUFA act as mediators in a series of processes in several reproductive tissues. Therefore the observed increase of PUFA may have a positive effect on the reproductive performance of cattle, such as higher pregnancy rate, greater number of follicles, or a faster restart of ovulation postpartum (reviewed by Herrera-Camacho [ 6 ]). These results will also help to better follow and understand metabolic pathways of fatty acids not only in relation to modified nutrition, but also to parity and stage of lactation.…”

“…Numerous studies on cattle have shown that increased fat content in a ration increases the number and size of ovarian follicles, and reduces the time to the first ovulation after calving [ 4 ]. It was also observed that supplementation with PUFA increases the amount of precursors for the synthesis of steroid hormones (estradiol, progesterone), prostaglandins (PGF2α), and decreases embryo mortality [ 5 , 6 ]. For this reason, it is crucial to understand changes in the composition of tissues that occur during fat supplementation, together with other traits, which may affect this composition, such as parity and stage of lactation.…”

This article addresses the hypothesis that lactation stage, parity and energy-protein feed additive affect fatty acid composition of blood, liver and adipose tissue of cows. The experiment was conducted on 24 Polish Holstein-Friesian cows divided into two feeding groups. One group of cows was fed solely a total mixed ration, while the other group was fed a ration with the addition of 2 kg of energy-protein supplement per cow/day. During the experiment, the samples of liver, adipose tissue and blood were taken and their fatty acid compositions were determined. Analysis of variance was applied to fatty acid relative weight percentage to determine the effect of the stage of lactation, parity, and energy-protein supplement on the fatty acid composition of the tissues. Stage of lactation had a significant impact on the content of many fatty acids in all examined tissues. We found that parity had no effect on fatty acid composition of blood, whereas it significantly affected C16:1 c9 in liver, and C16:1 c9 and C18:0 in adipose tissue. Energy-protein supplement significantly affected the content of most fatty acids in blood (e.g., C18:1 t11 and C18:3 n-3) and liver (C18:3 n-3, both isomers of conjugated linolenic acid and n-3 fatty acids derived from fish oil), but it did not affect the profile of the adipose tissue of cows. According to our best knowledge, this is the first study showing the relationship between parity, stage of lactation and the composition of fatty acids in blood, liver and adipose tissue of cows.

“…1 Different dietary fats, fed to ruminant animals, have been observed to improve reproductive function. 2 There is evidence that the lipid composition of the sperm membrane is a determinant of the motility, cold sensitivity and overall viability of sperm. 3 Polyunsaturated fatty acids (PUFAs) act as mediators in various processes in some reproductive tissues, including fluidity of cell membranes, intracellular signaling and susceptibility to oxidative damage.…”

The influence of dietary sunflower oil, rich in n‐6 polyunsaturated fatty acids, in combination with vitamin C on ram semen parameters, sperm lipids and fertility

BACKGROUND Dietary fats, fed to ruminant animals, have been observed to improve reproductive function. Sunflower oil is one of the richest sources of polyunsaturated fatty acids (PUFAs), over 60% of which is linoleic acid (C18:2). With regard to recommendations for increased consumption of PUFAs, special emphasis has been given to the importance of consuming more antioxidants to prevent lipid peroxide formation. This study evaluated the effects of dietary n‐6 PUFAs and vitamin C (VC) in rams – in particular, on semen quality, blood metabolites, sperm lipids and overall fertility. RESULTS Diets supplemented with SFO and VC increased the proportion of motile sperms and their progressive motility improved (P < 0.01). Rams fed a diet containing SFO had an increased proportion of sperms with normal acrosomes in their semen samples (P < 0.01). The highest levels of lactate dehydrogenase activity (LDH) enzyme were found in control rams (2.60 U mL−1). Feeding SFO significantly affected blood triglyceride and cholesterol concentrations (P < 0.05). Diets containing SFO increased the proportion of C18:2c, C20:4, C20:3 and C22 in the sperm lipid composition (P < 0.05). Semen of SFO and VC‐fed rams was more fertile than that of control rams when it was artificially inseminated to ewes. CONCLUSION Feeding rams with supplemental SFO and VC increased semen quality and improved fertility rates. © 2019 Society of Chemical Industry
