A mixture of the same E. coli cultures was added to the poults' water troughs to attain a concentration of approximately 10(6) cfu/mL on a weekly basis to ensure a continuous bacterial challenge.

This experiment yielded eight treatments per challenge group. At Weeks 1 and 3, eight birds from each treatment from the E. coli challenged and unchallenged groups were randomly chosen for bacterial sampling of liver and intestinal tissue for coliforms, aerobic bacteria, and Lactobacillus spp. E. coli isolates from tissue samples were O serotyped. During E. coli challenge, dietary Bio-Mos and Flavomycin improved poult BW and BW gains (P < or = 0.05). When poults were not challenged with E. coli, poults from old hens had improved BW and cumulative BW gains over poults from young hens (P < or = 0.05).

Intestinal isolates demonstrated more incidences of resistance to chlortetracycline (CTC), gentamicin (GEN), enrofloxacin (ENO), neomycin (NEO), and sulfadimethoxine-ormetoprim (SDM-ORM) when cultured from poults from young hens (YHP, 15 weeks of lay) (p ≤ 0.05). Liver isolates demonstrated varied hen age differences to GEN (p ≤ 0.05). However, liver isolates cultured from YHP showed higher levels of resistance to NEO and SDM-ORM and lower levels of resistance to ENO (p ≤ 0.05). All isolates cultured were resistant to clindamycin (CLD) and bacitracin (BAC), and no less than 96.6% of the isolates cultured were resistant to penicillin (PEN). Isolates from Hatchery 1 and 2 exhibited strong susceptibility to ENO, but, in Hatchery 3, results to ENO varied. The results were more variable when breeder flocks were followed from young to old, which may be due to pronounced seasonal effects. In conclusion, E. coli isolates from YHP have a higher incidence of resistance to antibiotics than E. coli isolates from OHP. These data suggest that age of breeder flock and hatchery-related environmental differences might influence the effectiveness of antibiotics against avian E. coli isolates from turkey poults.}, number={4}, journal={JOURNAL OF APPLIED POULTRY RESEARCH}, author={Fairchild, AS and Grimes, JL and Wineland, MJ and Jones, FT}, year={2000}, pages={487–495} } @article{tharrington_curtis_jones_anderson_1999, title={Comparison of physical quality and composition of eggs from historic strains of single comb white leghorn chickens}, volume={78}, DOI={10.1093/ps/78.4.591}, abstractNote={The effect of long-term genetic selection on physical quality and composition of eggs was determined by analyzing eggs acquired from Agriculture Canada: Ottawa Control Strain 5 (CS5) from a 1950 base population, 7 (CS7) from a 1958 population and 10 (CS10) from a 1972 population. Eggs from the H&N "Nick Chick" current commercial strain (CCS) were also included. Eggs were collected monthly over a 62-wk laying period and analyzed for egg, albumen, shell and yolk weight; albumen protein, solids and pH; percentage yolk solids and fat; Haugh units; and specific gravity. Significant (P < 0.05) differences found between strains included a progressive increase in weight of eggs from the CS5 to CCS. Although the eggs increased in size, no significant differences were found between strains for specific gravity or percentage shell weight. Yolk weights of eggs from the strains examined did not differ. However, the percentage of yolk found in current strain eggs was significantly lower (P < 0.05), with a subsequent higher percentage albumen due to the increase in egg size of the CCS. Haugh units were significantly higher in the CS10 and CCS strains than in the other strains. No significant differences between strains were seen in albumen protein, solids, pH, or yolk solids. Mean percentage yolk fat assay values for eggs from the CS5, CS7, CS10, and CCS strains were 33.08, 32.68, 32.84, and 32.40, respectively. Percentage yolk fat values obtained from CCS were significantly lower (P < 0.05) than those obtained from the other strains. The results from this study indicate that genetic selection has produced larger eggs containing a lower percentage of yolk while overall egg quality has been maintained or improved.}, number={4}, journal={Poultry Science}, author={Tharrington, J.

The effects of irradiation (5 kGy) on the indigenous feed microflora and on the survival of marker strain of S. typhimurium contaminated after irradiation treatment were determined during 56 days of storage of either soybean meal (SBM) or meat and bone meal (MBM) based feeds. The initial aerobic bacterial populations were reduced more than 90% in both SBM (4.96 to 4.08 ± 0.03 log10 CPU/g feed) and MBM (5.12 to 3.90 ± 0.03) by irradiation.

Contaminated corn was ground and mixed with litter to carbon:nitrogen ratios of 30:1. Moistures were adjusted by adding tap water just prior to incubation or stacking. The initial laboratory trial included only broiler litter at 40% moisture, whereas the subsequent field trial involved a 2 x 2 factorial design with litter type (turkey or broiler) and moisture (20 or 40%) as main effects. Aflatoxin assays were reduced in the laboratory trial from 433 and 402 to 54 and 8 ppb in Containers 1 and 2, respectively, after 35 d of incubation at 28 C. In the field trial, aflatoxin disappeared from broiler and turkey litter mixtures with projected moistures of 20% after 10 and 6 wk of storage, respectively, whereas disappearance in mixtures containing projected moistures of 40% required 5 and 3 wk, respectively. Differences in moisture appear to account for differences in the ability of turkey and broiler litter to detoxify aflatoxin. Hence, turkey and broiler litter would appear equal with respect to the ability to detoxify aflatoxin-contaminated corn. Disappearance of aflatoxin during storage with litter could have occurred as a result of ammonia release during storage or microbial detoxification mechanisms. However, nitrogen values suggest that microbial action was responsible for much of the detoxification, as aflatoxin disappeared from mixtures with little apparent ammonia release.}, number={1}, journal={POULTRY SCIENCE}, author={Jones, FT and Wineland, MJ and Parsons, JT and Hagler, WM}, year={1996}, month={Jan}, pages={52–58} } @article{jones_anderson_ferket_1995, title={Effect of Extrusion on Feed Characteristics and Broiler Chicken Performance}, volume={4}, ISSN={1056-6171}, url={http://dx.doi.org/10.1093/japr/4.3.300}, DOI={10.1093/japr/4.3.300}, abstractNote={Abstract Broiler feeds of identical formulas were fed to straight run broilers in the form of either non-heat treated mash, pellets, or extruded pellets to test the effect of feed processing on production parameters.

However, when broilers received rations not crumbled following processing, birds fed extruded diets weighed less than those fed pelleted diets. Extruded feeds weighed less per unit volume than pelleted feeds. This density difference may account for the differences in body weights observed. The traditional ether extraction procedure detected a smaller percentage of the fat present in extruded feeds than did acid hydrolysis procedures. In addition, the extrusion process caused some protein and amino acid destruction.
