Abstract

This study was conducted in the poultry field of the Department of Animal Production / College of Agriculture / University of Basrah during the period from 5/20/2021 to 6/23/2021 to find out the effect of adding imported phytogenic to feed and water for broiler chickens according to the completely randomized design (CRD), for differences between transactions and to compare it with a mixture of local oil and for different periods of time. on some immune traits of broiler chickens. 324 one-day-old broiler chicks were randomly distributed to 9 treatments:
T1 without adding, T2 adding 150 mg PFA / kg of feed from the period (1-5) weeks of the age of the experiment, T3 adding 3 ml liquid PFA / liter of drinking water from the period (1-5) weeks, T4 adding 3 ml Local oil mixture / kg of feed from (1-3) weeks, T5 adding 3 ml of local oil mixture / kg of feed from (3-5) weeks, T6 adding 3 ml of local oil mixture / kg of feed from (1-5) weeks, T7 add 3 ml of local oil mixture/ liter of drinking water from (1-3) weeks, T8 add 3 ml of local oil mixture / liter of drinking water from (3-5) weeks, T9 add 3 ml of local oil mixture / liter of drinking water from (1-5) weeks. The results showed a significant superiority of all the experimental treatments in feed and water over the control treatment T1 (without addition) in the immunological characteristics studied in the experiment, which is the balance of intestinal flora in the jejunum of the small intestine (total bacteria, and increase in lactic acid bacteria, a decrease in pathological coliform bacteria). Coli, and the results showed a significant superiority of all experimental treatments in the volumetric measure of antibodies against Newcastle disease and Camboro disease at the age of 35 days compared to the control treatment T1 (without addition).
