Layers diets typically contain 15-20% soya due to its high crude protein content (ca. 36%). Reliance on soya for protein can result in large increases in cost of feed due to the law of supply and demand as a global commodity. Lupin grains have high protein content (35-40%) but previous experience with white lupins has shown toxic effects in poultry due to high levels alkaloids and poor performance due to anti-nutritional Non-starch polysaccharides (NSP). Here blue lupins either processed or whole were trialled for their potential as a protein source...

An experiment was conducted with 160 Hisex Brown laying hens to evaluate the effect of different inclusion levels of faba bean (FB) and enzyme supplementation on productive performance and egg quality parameters. The experimental diets consisted of five levels of FB: 0% (control), 25%, 50%, 75% and 100%, substituting soybean meal (SBM), and two levels of enzyme supplementation (0 or 250 mg/kg). Each dietary treatment was assigned to four replicate groups and the experiment lasted 22 weeks. A positive relationship (P < 0...

Sialidase catalyzes the removal of sialic acids from glycoconjugates. Recently, medaka sialidase Neu1 has been cloned and its enzymatic properties were investigated. Although enzymatic properties of this sialidase, such as optimal pH and substrate specificity, exhibits high similarity with human NEU1, Neu1 physiological functions in fish are still unclear. Here, to understand Neu1 significance in medaka embryogenesis, sialidase translation knockdown was carried out with one-cell stage fertilized egg using morpholino oligo injection...

Malaria, schistosomiasis and leishmaniases are among the most prevalent tropical parasitic diseases and each requires new innovative treatments. Targeting essential parasite pathways, such as those that regulate gene expression and cell cycle progression, is a key strategy for discovering new drug leads. In this study, four clinically approved anti-cancer drugs (Vorinostat, Belinostat, Panobinostat and Romidepsin) that target histone/lysine deacetylase enzymes were examined for in vitro activity against Plasmodium knowlesi, Schistosoma mansoni, Leishmania amazonensis and L...

OBJECTIVE/BACKGROUND: Mycobacterium avium subsp. paratuberculosis is a slow growing, Gram-positive, and acid-fast bacillus. It is the causative agent of the chronic enteritis disease of ruminants called Johne's disease. Most of the infected animals are young. However, most clinical cases belong to adult cattle aged 3-5years. Due to a prolonged incubation period, identification of subclinically infected animals is one of the most crucial problems in Johne's disease. The aim of this study was to detect M...

In this work we present the synthesis, aqueous solubility and stability, hydrolysis by alkaline phosphatase, and in vivo fasciolicidal activity in sheep of a highly water soluble phosphate salt prodrug of triclabendazole (MFR-5). The aqueous solubility of MFR-5 at pH 7 was 88,000-fold that of triclabendazole. MFR-5 showed excellent aqueous stability (>95% after 26h) at pH 7, making it ideal for developing pharmaceutical compositions in the form of solutions that can easily be hydrolyzed by the enzyme alkaline phosphatase (t=13...

Diapause is a common biological phenomenon that occurs in many organisms, including fish, insects, and nematodes. In the silkworm (Bombyx mori), diapause generally occurs in the egg stage. Treatment with O₂, HCl, or other compounds can prevent egg diapause. Here, we characterized the transcriptomic responses of newly laid eggs treated with O₂ or HCl. Digital gene expression analysis showed that 610 genes in O₂-treated eggs and 656 in HCl-treated eggs were differentially expressed. Of these, 343 genes were differentially expressed in both treatments...

Functional foods enriched with folate may be beneficial as a means of optimizing folate status in consumers. We recently developed novel eggs enriched with folate through folic acid supplementation of the hen's feed, but their potential to influence consumer folate status is unknown because the natural folate forms incorporated into the eggs may not necessarily be retained during storage and cooking. This study aimed to determine the stability of natural folates in folate-enriched eggs under typical conditions of storage and cooking...

To elucidate the mechanism for embryonic diapause or the breakdown of diapause in Bombyx mori, we biochemically analyzed nitric oxide synthase (NOS) during the embryogenesis of B. mori. The gene expression and enzyme activity of B. mori NOS (BmNOS) were examined in diapause, non-diapause, and HCl-treated diapause eggs. In the case of HCl-treated diapause eggs, the gene expression and enzyme activity of BmNOS were induced by HCl treatment. However, in the case of diapause and non-diapause eggs during embryogenesis, changes in the BmNOS activity and gene expressions did not coincide except 48-60 h after oviposition in diapause eggs...

Induced pause in egg laying simulates natural molting events in which the hen's reproductive organs regress and rejuvenate. Such processes require extracellular matrix remodeling that is maintained, at least in part, by the action of proteolytic enzymes known as matrix metalloproteinases (MMPs). Nevertheless, information concerning the expression and hormonal regulation of MMP system members in chickens is scarce. Therefore, MMP-2, -7, and -9 and their tissue inhibitors (TIMP-2, -3) expression and localization were investigated in all segments of the domestic hen oviduct (infundibulum, magnum, isthmus, shell gland, vagina) during a pause in egg laying induced by tamoxifen (TMX)-an estrogen receptor modulator...

BACKGROUND: Ancylostoma species have demanded attention due to their zoonotic potential. The use of anthelmintics is the usual method to prevent environmental contamination by Ancylostoma eggs and larvae. Nematophagous fungi have been widely used in their biological control due to the fungus ability to capture and digest free nematode forms. AIMS: The aim of this study was to evaluate the effect of four different fungal extracts of Paecilomyces lilacinus (n=2), Trichoderma harzianum (n=1) and Trichoderma virens (n=1) isolates on the hatchability of Ancylostoma eggs...

REVIEW

The endocannabinoid system (eCS), is a complex system, comprising the main endogenous ligands anandamide and 2-arachidonoyl glycerol, the cannabinoid receptors CB1 and CB2 and the biosynthetic and degrading enzymes. Cumulative evidence shows that the eCS plays an important role in reproduction, from egg fertilization to parturition. Therefore, alterations in this system, either by recreation/therapeutic use of cannabis or deregulation of the endogenous cannabinoids, might lead to adverse pregnancy outcomes, including retardation in embryo development, poor blastocyst implantation, inhibition of decidualization, miscarriage and compromised placentation...

In the past few decades, extensive application of azoxystrobin has led to great concern regarding its adverse effects on aquatic organisms. The objective of the present study was to evaluate the reproductive toxicity of azoxystrobin to zebrafish. After adult zebrafish of both sexes were exposed to 2, 20 and 200 μg/L azoxystrobin for 21 days, egg production, the fertilization rate, the gonadosomatic index (GSI) and hepatosomatic index (HSI), 17β-estradiol (E2), testosterone (T) and vitellogenin (Vtg) concentrations, and histological alterations in the gonads and livers were measured...

We report detection of <13 CFU of Salmonella per 25 g egg white within 7 h by concentrating the bacteria using microfiltration through 0.2-μm cutoff polyethersulfone hollow fiber membranes. A combination of enzyme treatment, controlled cross-flow on both sides of the hollow fibers, and media selection were key to controlling membrane fouling so that rapid concentration and the subsequent detection of low numbers of microbial cells were achieved. We leveraged the protective effect of egg white proteins and peptone so that the proteolytic enzymes did not attack the living cells while hydrolyzing the egg white proteins responsible for fouling...
