“…However, this impairment in FE was not consistently observed among the experiments reported by Klasing et al (1987a) and Klasing and Barnes (1988). Furthermore, Piquer (1994) observed in preliminary research with 1-d-old turkey poults that LPS injection caused an impairment in FE only for the age period of 1 to 3 d.…”

“…The induction of an immunological stress in turkeys by injection of LPS from Escherichia coli has been reported by Klasing et ah (1987b) and Piquer (1994). Klasing et ah (1987b) reported increased liver Zn and serum Cu concentrations after LPS or IL-1 injection into turkey embryos (16 d of incubation) and 1-d-old turkeys.…”

“…Dosage of LPS was reduced for the third injection because results of a preliminary experiment showed that mortality was very high after a third injection of the same dose given in the first two injections. No uninjected controls were included in either experiment on the basis of the equal growth of SAL-injected and uninjected controls observed in preliminary research (Piquer, 1994).…”

“…Klasing et ah (1987b) reported increased liver Zn and serum Cu concentrations after LPS or IL-1 injection into turkey embryos (16 d of incubation) and 1-d-old turkeys. Piquer (1994) reported that the injection of E. coli LPS into newly hatched turkeys caused marked reductions in BW gain and feed intake as compared with a control group.…”

“…Furthermore, Benson et ah (1993) reported that the determined ME of four diets fed to LPS-injected broiler chickens was not affected by injection of the immunogen. In preliminary research (Piquer, 1994), it was estimated that dietary ME n would have to range from 3,200 to 4,400 kcal/kg to equalize ME n intake of LPS-injected turkeys to that of control turkeys fed a diet with 2,800 kcal ME n /kg. Other authors have used anti-inflammatory drugs such as ibuprofen and acetylsalicylic acid to overcome the adverse effects of an immune stress on growth or feed intake of rats (Hellerstein 4 Sigma Chemical Co., St. Louis, MO 63178-9916.…”

Two experiments were conducted to document the effects of an early immunologic stress and changes in dietary ME(n) on growth and nutrient utilization of newly hatched turkeys. Treatments in both experiments consisted of a complete factorial arrangement of two types of injection and four isonitrogenous diets. Turkeys were injected i.p. with saline (SAL) or a solution of lipopolysaccharide (LPS) (100 micrograms LPS/mL SAL) at 1, 3, and 5 d of age. In Experiment 1, two diets were formulated to contain 2,800 kcal ME(n)/kg. One was a corn-soybean meal-based diet (CSBM) and the other contained 8% Solkafloc (SKF). A third diet (3,100 kcal ME(n)/kg) was formulated by substituting 8% sucrose (SUC) for the 8% SKF. The fourth diet included in Experiment 1 was formulated to contain 3,700 kcal ME(n)/kg. The CSBM and SUC diets were also included in Experiment 2. Two additional diets tested in Experiment 2 were the CSBM diet containing 74.5 mg ibuprofen/kg (IBU) and a corn-soybean meal-based diet with a ME(n) value of 3,100 kcal/kg (CS31). Injection with LPS reduced (P < .05) BW of turkeys throughout Experiment 1 and until 9 d of age in Experiment 2, as compared with injection with SAL, irrespective of dietary treatment. The reduction in BW was mainly due to a decrease in feed intake (FI) (P < .05). Turkeys fed diets with 3,100 kcal ME(n)/kg were heavier (P < .05) than those fed diets with 2,800 kcal ME(n)/kg, irrespective of injection. Inclusion of ibuprofen to the CSBM diet from 1 to 14 d improved (P < .05) BW and feed efficiency (P < .01) of turkeys at 14 d of age, compared with turkeys fed the CSBM diet. Determined ME(n) was not affected by LPS injection. Adverse effects of LPS injection on growth of turkey poults were mainly the consequence of a reduced FI and not of altered nutrient utilization. These effects were not fully alleviated by feeding a diet with 3,100 kcal ME(n)/kg.

Two 21-d experiments were conducted to document the effects of an early immunologic stress and changes in dietary ME(n) on selected characteristics of immune function of newly hatched turkeys. Eight treatments were included in each experiment. Treatments were the result of complete factorial arrangements of two types of injection and four isonitrogenous diets. Turkeys in both experiments were injected i.p. with .5, .5, and .2 mL of saline (SAL) or .5, .5, and .2 mL of a solution of Escherichia coli lipopolysaccharide (LPS) (100 micrograms LPS/mL SAL) at 1, 3, and 5 d of age, respectively. In Experiment 1, two diets were formulated to contain 2,800 kcal ME(n)/kg. One was a corn-soybean meal based diet (CSBM) and the other contained 8% Solkafloc (SKF). A third diet (3,100 kcal ME(n)/kg) was formulated by substituting 8% sucrose (SUC) for the 8% SKF. The fourth diet (HE) included in Experiment 1 was formulated to contain 3,700 kcal ME(n)/kg. The CSBM and SUC diets and two additional diets were tested in Experiment 2. The latter were the CSBM diet containing 74.5 mg ibuprofen/kg (IBU) and a corn-soybean meal diet formulated to contain 3,100 kcal ME(n)/kg (CS31). Concentrations of plasma IgG and jejunal IgG and IgA were not affected by injection or diet. Age-related changes in Ig concentrations were consistently observed in Experiments 1 and 2. Injection with LPS reduced the number or responses of blood leukocytes to mitogens at 8 d of age (P < .01), as compared with samples from turkeys injected with SAL. Leukocytes in whole blood samples from turkeys fed the HE diet responded less to LPS stimulation than those fed the SUC diet (P < .01). Injection with LPS did not markedly affect the characteristics of immune function studied, and feeding a diet with 3,100 kcal ME(n)/kg and 28.5% crude protein did not measurably affect the characteristics of immune function of young turkeys.
