Effects of supplementing broiler breeder diets with organic selenium and polyunsaturated fatty acids on egg quality during storage

Abstract

We assessed the effects of supplementation of broiler breeder diets with polyunsaturated fatty acids (PUFA) and organic Se on hatching egg quality during storage. Broiler breeders (n = 352) were fed 1 of 4 diets: SO (soybean oil with no added Se), SO with Se (SO+Se), fish oil (FO), or FO and Se (FO+Se). Eggs from prepeak (23 wk) and peak production (27 wk) breeders were stored for 14 d under typical (15 degrees C, 78% RH) conditions. Eggs were analyzed for albumen Haugh units (HU) and pH, shell characteristics, egg component weight, Se content, and fatty acid (FA) profile. The efficiency of transfer of Se into the egg was greater in low Se treatments compared with in high Se treatments. The majority of Se from the low Se treatments was deposited in the yolk, whereas in high Se treatments, the Se was deposited evenly in the yolk and albumen. In the low Se treatments, the Se content of yolk and albumen was lower than in the high Se treatments and decreased as age increased. Albumen HU decreased with increased storage, although high Se treatments had greater HU compared with low Se treatments. Eggs from the FO treatment were smaller with thinner eggshells compared with the SO treatment, but addition of Se to the FO diets ameliorated some of these effects. The egg yolk FA profile from the SO+Se treatment was altered compared with that from the SO treatment, perhaps due to interactions between dietary PUFA and Se-dependent enzyme systems. Hatching egg quality during storage was affected by dietary PUFA and Se content, as well as broiler breeder age.

Effects of Fish Oil and Tomato Powder Supplementation in Mojosari Ducks Diet on Egg Quality

“…This result may be due to the low level of fish oil supplementation. In another study, addition of fish oil at 5.5% could reduce egg yolk and albumen of broiler breeder [14]. It could be stated that supplementation of fish oil until 2% had no detrimental effect on egg quality.…”

Ovarian follicular development, lipid peroxidation, antioxidative status and immune response in laying hens fed fish oil-supplemented diets to produce n-3-enriched eggs

“…This response was similar to observations by Gonzalez-Esquerra and Leeson (2000) who reported that egg weight decreased (P < 0.05) linearly with increasing menhaden oil (2%, 4% and 6%). Also, Pappas et al (2005) established that inclusion of fish oil significantly reduced the weight of the egg that was laid, as well as of its component parts. These results were in agreement with some published work Mean values followed by different letters in the same row are significantly different (P < 0.05).…”

“…Taking into account the involvement of GSH-Px in the immune function, it is important to note that the antioxidative enzyme GSHPxs are likely to protect neutrophils from oxygen-derived radicals that are produced to kill ingested foreign organisms (Arthur, 2000). Furthermore, GSH-Px plays an important role in regulation of the biosynthesis of prostaglandins from their precursor, ARA; however, the precise nature of GSH-Px involvement in eicosanoid metabolism is not fully understood (Pappas et al, 2005). Interestingly, it is important to mention that fish oil can decrease the oxidation products generated by the inflammatory cells which accompany ischaemic reperfusion.…”

“…However, Cortinas et al (2003) summarised that egg production was significantly higher when laying hens were fed diets containing 4% fish oil or flaxseed oil. Contrarily, other researchers have reported impaired production parameters in hens fed fish products, and particularly reduced egg weight (Pappas et al, 2005).…”

“…Furthermore, GSH-Px plays an important role in the regulation of biosynthesis of prostaglandins from their precursor, arachidonic acid (ARA, 20:4; n-6). However, the precise nature of GSH-Px involvement in eicosanoid metabolism has not been fully understood yet (Pappas et al, 2005). Interestingly, it is important to mention that FO can decrease the oxidation products generated by the inflammatory cells which accompany ischaemic reperfusion.…”
