          Digestion and absorption in the young chick.

           YAEL NOY,  DAVID SKLAN (1995)
          Digestion, enzyme secretion and intestinal rate of passage were determined in broiler chicks from hatch until 21 d using 141Ce as a nonabsorbed reference substance. Body weight and feed intake increased more rapidly after 10 d posthatch, and, in parallel, time of passage of feed through the intestines decreased by approximately 33%. Net duodenal secretion of amylase, trypsin, and lipase was low at 4 d and increased 100-, 50-, and 20-fold, respectively, by 21 d. Enzyme activity decreased distally in the small intestine. This change was greater with age. The contribution of the ileum to fatty acid absorption decreased after 7 d. Small intestine digestion of nitrogen increased from 78% at 4 d to 92% at 21 d, whereas fatty acid and starch digestion ranged from 82 to 89% in this period. It appears that digestibilities of starch and lipids are not limiting factors in the growth of young chicks.

            Relationship between the level of dietary vitamin E and the immune response of broiler chickens.

            The relationship between the dietary level of vitamin E (VE) and the immune response of broilers was studied in three experiments. Immunity was assessed as antibody production to infectious bronchitis virus (IBV), SRBC, and Brucella abortus (BA) antigens, mitogenic response to phytohemagglutinin A (PHA) and concanavalin A (Con A), cutaneous basophil hypersensitivity (CBH) to PHA, and lipopolysaccharide induction of acute-phase proteins (APP) and heterophilia. A range of VE (0, 10, 17.5, 25, 37.5, 50, 100, and 200 IU/kg) levels were supplemented to a basal diet (corn-soy) containing 10.2 IU of VE/kg. We found a dose-dependent increase in antibody production in response to attenuated IBV between 0 and 25 IU/kg of supplemented VE and no further increase at higher levels. Antibody levels to SRBC were higher in birds supplemented with 50 IU of VE/kg compared to those supplemented with 0 or 200 IU/kg of VE. Antibody production in response to BA antigens was not influenced by VE. Mitogenic responses were suppressed by supplemented VE in Experiment 1 for PHA (25 IU/kg diet) and Con A (25 and 50 IU/kg diets). CBH and APP levels were not affected by VE. Heterophilia was lowest at 50 IU/kg 6 h after lipopolysaccharide injection (Experiment 1). Our study showed that moderate (25 to 50 IU/kg) levels of VE supplementation were most immunomodulatory and that high levels were less effective.
