Growth Response and Resistance to Edwardsiella ictaluri of Channel Catfish, Ictalurus punctatus, Fed Diets Containing Distiller’s Dried Grains with Solubles
A study was conducted to examine the effect of dietary levels of distiller’s dried grains with solubles (DDGS) on growth, body composition, hematology, immune response, and resistance of channel catfish, Ictalurus punctatus, to Edwardsiella ictaluri challenge. Five diets containing 0, 10, 20, 30, and 40% DDGS with supplemental lysine (Diets 1–5) as partial replacements of a combination of soybe...
متن کاملEffects of GH on immune and endocrine responses of channel catfish challenged with Edwardsiella ictaluri.
The effects of GH on immune and endocrine responses to channel catfish challenged with the bacterium Edwardsiella ictaluri were examined. Catfish (11.7+/-1.0 g) treated with recombinant bovine growth hormone (rbGH) and challenged with E. ictaluri experienced similar mortality as control-exposed fish. Plasma activity of lysozyme was higher (P<0.01) in rbGH-exposed fish. Compared to day 0 control...
متن کاملGrowth Performance and Feed Conversion Efficiency of Crossbred Heifers
Theexperiment was conducted to investigate the growth performance and feed conversion efficiency of crossbred heifer at different age level in Government Dairy Farm in Bogra, Bangladesh. Twelve female crossbred heifers were equally distributed (n=3) into four groups [Group A: (7±2 months), B: (12±2 months), C: (15±2 months) and D: (20±2 months)] according to age and fed concentrate mix, rice st...
متن کاملEffects of cortisol and stress on channel catfish (Ictalurus punctatus) pathogen susceptibility and lysozyme activity following exposure to Edwardsiella ictaluri.
Periods of stress are often associated with disease outbreaks in cultured fish, and stress is often characterized by the secretion of cortisol. Although stress and cortisol secretion are highly correlated in fish, the role of cortisol in affecting channel catfish (Ictalurus punctatus) pathogen susceptibility is unclear. The effects of short-term stress and exogenous cortisol administration on c...
متن کاملPathogen Levels, Lysozyme, and Cortisol Response in Channel Catfish with Susceptibility Differences to Edwardsiella ictaluri
—Differences in bacterial loads, clearance rates, nonspecific immune response, and cortisol response were measured for three family groups of channel catfish Ictalurus punctatus susceptible to enteric septicemia of catfish (ESC) and three ESC-resistant families. Resistant families had lower mortality during challenge (P , 0.0001). Bacterial loads on day 5 postexposure were higher (P , 0.01) in ...
