The visceral storage fat and liver of patin catfish (Pangasianodon hypophthalmus) are normally discarded, which incurs cost and can cause environmental pollution. However, these may be potential sources to extract fish oil. The proximate and fatty acid compositions of liver and fatty tissue of patin catfish were investigated to evaluate the suitability of these by-products for extracting fish o...

Turkey sperm plasma membranes contain high levels of polyunsaturated fatty acids that are susceptible to lipid peroxidation during in vitro storage at 4 degrees C. Herein we assessed the degree of lipid peroxidation and fertility potential of semen liquid-stored for 24 h with the antioxidant vitamin E. Semen was collected weekly from 44 males and pooled as pairs (total = 22); the individuals in...

Spermatozoa represent a tissue readily accessible for study after various exogenous perturbations. To characterize the lipid composition of monkey sperm and to establish a baseline from which dietary or pharmaceutical influences may then be evaluated, we collected semen samples from five rhesus monkeys by electroejaculation and analyzed the sperm for sterols, fatty acid composition, and the mol...

The aim of this study was to evaluate the effects of dietary supplementation with different fish oils (rich in PUFA) vs. hydrogenated animal fat (SFA) on semen production and quality, fatty acid composition, and preservation properties in boars under controlled and commercial conditions. In Exp. 1 (in a research station), 44 boars, allocated to 4 dietary treatments, received daily 2.5 kg of bas...

   Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...

changes in the fatty acid composition and biochemical indices of mackerel (which has a substantial lipid content) and shark (which has negligible lipid content) fillets stored at - 18°c for up to six months were measured. lipid content was measured (6.35% and 1.38%) in mackerel and shark, respectively; however it decreased during frozen storage in both fish species. in analysis of fatty acids t...

Study objectives were to; 1) determine if supplementing of n-3 fatty acids improves membrane integrity, and hence viability and motility of stallion spermatozoa following cold storage, and following cryopreservation, and 2) determine if n-3 supplementation alters the fatty acid composition of stallion spermatozoa. Data indicate that following 90 d of n-3 supplementation daily sperm output and t...

Background: Feeding unsaturated fatty acids sources in dairy cows is considered as a strategy to improve animal health during postpartum period and milk fatty acid profile. OBJECTIVES: This study aimed to investigate the effects of conjugated linoleic acid supplement and combination of sesame meal and oil on performance and milk fatty acid composition of dairy cows during transition period.
