Selenium (Se) is a multifunctional trace element required in specific amounts for the optimal growth of aquatic finfish species. For this reason, study investigated effect Se nanoparticles on behavior, antioxidative capacity, and liver wellbeing Striped catfish (Pangasianodon hypophthalmus). fed varying levels (0. 0.5, 1, 2 mg/kg) triplicate units kept 60 days. delivered dietary had markedly increased performance, rate (SGR), consumed feed, protein efficiency ratio but reduced feed...
This study investigated the influence of lactoferrin (LF) and N-acetylcysteine (NAC) on growth rate immune response Egyptian Baladi goats. Thirty-five goat kids (2.765 ± 0.135) were comprised seven groups, each with five individuals. The control group received neither LF nor NAC. subsequent groups daily doses at 50 mg, 100 or 200 mg Similarly, other administered per day. Biweekly assessments used to measure weight gain (DWG) offspring. Additionally, blood samples collected every 20, 40, 60...
Titanium dioxide nanoparticles (TiO2 NPs) are used in numerous products, such as paints, pharmaceuticals, environmental sanitizing agents and even a whitening food additive (E171). Residual TiO2 NPs considered among the emerging contaminants of aquatic environments. However, effect exposure on intestinal microbiota population, microbial disease resistance immune-related gene expression Nile tilapia (Oreochromis niloticus) is largely obscure. Three groups fish were nurtured diets containing 1...
Abstract The present study aimed to evaluate the effect of organic and inorganic selenium (Se) supplementation on semen quality blood serum profiles buffalo bulls. Nine mature bulls were divided into three groups: control (non‐supplemented); Se (10 mg Sel‐Plex®/head twice weekly) sodium selenite/head weekly). Semen was collected a week for 3 months during supplementation. properties evaluated from fresh ejaculate. Moreover, fructose concentration, aspartate alanine transaminase (AST ALT)...
Spermatozoa can experience negative changes when subjected to freezing and thawing, including lowered motility, viability acrosome response. Herein, the effects of different concentrations soybean lecithin nanoparticles on cryopreserved Holstein bull semen were examined. Semen was collected, utilized for sperm kinetic parameter analysis following dilution, equilibration thawing with 0.5% (E1), control extender, 0.75% (E2), (E3), 0.25% (E4) 0.125% (E5) nanoparticles. Results revealed that...
The competence of pre-pubertal buffalo heifers' oocytes for in vitro maturation, fertilization and development were studied compared with that the adult oocytes.Ovaries collected from local abattoir.The recovered antral follicles (3-8 mm) diameter by aspiration technique cultured TCM-199 medium supplemented 10% fetal calf serum(FCS), 10 IU/ml PMSG , 20 LH 1 μg/ml Estradiol 17 β 50 Gentamycin sulfate incubated 5% CO 2 high humidity 24 h at 38.5°C.Number per ovary insignificantly higher on...
Abstract It is crucial to ensure the suitable stocking density for Nile tilapia fry since among most consumed fish species globally. In this study, were distributed at three densities, 1000 fry/m 3 (low density, LD), 2000 (middle MD), and 4000 (high HD). Then each was subdivided into two groups where aquaria supplied with fresh dechlorinated water (FW, 0.35 g saline /L), other fortified underground brackish (BW, ≈ 8 /L). Subsequently, kept under these experimental conditions offered 40%...
This experiment aimed to study the relation of body condition score (BCS) with blood metabolites in dairy cow. At 8 weeks before expected parturition, 90 multiparous Friesian cows were divided according their into 3 groups: Group1: low (n=30, BCS≤2.58, thinner cows); Group2: medium BCS≤3.12, BCS Group3: high BCS≤4.75, obesity cows). The BCS, weight and back fat thickness recorded at -60, -21, -14, -7, 0, 7, 14 60 days related calving time. Blood samples taken time measurement for...
The objective of this study was to determine the effect dietary unsaturated fatty acids supplementation on productive and reproductive performance ram lambs.In study, 15 crossbred lambs (½Finnish × ½Rhamni) at 7 months age with an average live body weight 24.3±1.4kg were used divided into three groups (5 each).The first group fed control diet (G1).While, fish oil added level 1.5 3% total dry matter (DM) intake for G2 G3, respectively.Results indicated that end experimental period 34.2; 37 kg...
This study aimed to evaluate the effect of Sephadex column filtration technique post-diluted semen on freezing ability and fertilizing capacity buffalo semen. Four Egyptian bulls were used for collection. Semen was extended (37oC) at a rate 1:20 filtered using with G-75 (T2) or G-100 (T3) as compared un-filtrated (T1). in all treatments evaluated progressive motility, livability, abnormality intact acrosome spermatozoa post-diluted, post-equilibrated post-thawing Pregnancy diagnosis...
