A new chicken mononuclear cell line (MQ-NCSU) has been established. The starting material used to initiate this cell line was a transformed spleen from a female Dekalb XL chicken which had been experimentally challenged with the JM/102W strain of the Marek's disease virus. After homogenization, a single cell suspension of splenic cells was cultured using(More)
Respiratory macrophages (RM) of the turkey were elicited with a 1:4 (v/v) suspension of incomplete Freund's adjuvant in sterile phosphate-buffered saline injected directly into the abdominal air sacs. RM were purified by passage through a Ficoll-Hypaque gradient resulting in 95.7 +/- 5.9% purity and 94.8 +/- 12.3% viability. On days 7 and 9 postinjection,(More)
Effects of Newcastle disease virus (NDV) infection on the binding, phagocytic, and bactericidal activities of turkey respiratory macrophages were studied. Respiratory macrophages of the turkey demonstrated the presence of immunoglobulin (Ig) G and complement receptors but lacked IgM receptors. Respiratory macrophages from NDV-infected turkeys showed little(More)
Thirty female turkeys, inoculated into the caudal thoracic air sacs with Pasteurella multocida were examined from 0 to 6 hours post-inoculation (PI). The air sac reacted rapidly and intensely with exudation of heterophils. Circulating leukocyte and thrombocyte numbers remained normal except for an absolute lymphopenia by 6 hours PI. P. multocida was(More)
A combination vaccine (Bovi-Shield FP4 + L5, Pfizer Animal Health) containing modified-live virus (MLV) components against bovine herpesvirus-1 (BHV-1), bovine viral diarrhea virus BVDV), parainfluenza virus-3 (PI3), bovine respiratory syncytial virus (BRSV), and inactivated cultures of Leptospira canicola, grippotyphosa, hardjo, icterohaemorrhagiae, and(More)
Juvenile turkey hens were actively immunized against vasoactive intestinal peptide (VIP) prior to photostimulation to evaluate its effect on enhancing egg production. VIP antibody titers were generated in the VIP immunized hens and a greater rate of egg production per hen was observed compared to controls. In addition, the first egg laying cycle was(More)
Cryptosporidium meleagridis oocysts, originally isolated from droppings of commercial turkey poults with increased mortality due to viral (reovirus) hepatitis and enteritis, were treated with peracetic acid to kill companion bacteria and viruses and then propagated by passage in young turkeys. Thirty-eight 5-day-old large white turkey poults were inoculated(More)
The effect of early protein restriction on poult performance and mortality due to spontaneous turkey cardiomyopathy were examined in a facility that historically had a high incidence of the condition. Two thousand male turkey poults were divided into two equal subgroups for the first 4 weeks of life: one received standard commercial rations for the first 4(More)
Dietary intake of glutamate by postweaning pigs is markedly reduced due to low feed consumption. This study was conducted to determine the safety and efficacy of dietary supplementation with monosodium glutamate (MSG) in postweaning pigs. Piglets were weaned at 21 days of age to a corn and soybean meal-based diet supplemented with 0, 0.5, 1, 2, and 4 % MSG(More)
Ninety commercial broiler chickens were divided into three equal groups; 30 were injected with brain-heart-infusion broth into the cranial thoracic air sacs (controls), 30 were similarly inoculated with a culture of Escherichia coli, and 30 were similarly inoculated with E. coli cell-free culture filtrate. Birds were examined from 0 to 6 hours(More)
