Effect of Adding Plantago lanceolata L. Seed Powder on Some Productive trait , Physiological Traits and Immune Response of Broiler Chickens

This study was conducted to find out the effect of supplementing broiler diets with plantago lanceolata seed powder affected their productivity, biochemistry, immunity, intestine and hepatic
histomorphology. One-day-old Ross 308 broiler chicks were employed in our experiment, totaling two hundred (200). chicks came from an Iraqi commercial hatchery Al-Dewanea. This study lasted for 35 days, from December 24th/ 2021, to January 28th/ 2022, and was carried out at a chicken field in al-mussaib city.
There was a total of 200 chicks used in this study, and they were split evenly between four treatments (50 chicks each treatment) with two replication (of 25 chicks replicat) such as: Chicks in Group 1 (T1) were given a meal devoid of plantago lanceolata seed as their only source of plant protein (control group). Chicks in the second group (T2) were given a feed supplemented with plantago lanceolata seed (1gm / kilogram diet). Chicks in Group 3 (T3) were given a meal supplemented with plantago lanceolata seed (3 gm/kg fed diet). Group 4 (T4): The chicks were given a standard diet included plantago lanceolata seed (5 gm/kg) feed diet.
Productive performance (body weight, weekly weight gain, feed intake, and feed conversion ratio (FCR)) are only few of the variables included in the research. Checking kidney function (blood urea, creatinine), liver enzyme (AST,ALT), lipid profile, and protein biochemistry (globulin , albumin and total protein ). Reactions of the immune system (antibody titer against Newcastle disease (ND) and Gomboro disease (IBD) and histo change. Some indicators of productivity were assessed every week, while others were evaluated on day 35.
In comparison to the control group, the results showed that the live body weight and weight gain of broiler chicks fed plantago lanceolata seed (1gm., 3gm., 5gm. /kg diet) were considerably higher (basal diet). Birds given plantago lanceolata seed consumed much less food than control birds. The feed conversion ratio was significantly lower in all addition groups compared to the control group.
Lower levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were seen in groups (T2, T3, and T4) as compared to control group. Antibody titers against the (ND) were found to be considerably greater in the T2 group compared to the other study .
There were no statistically significant variations in the relative weights of organs among groups liver, bursa, and Fabricius index
