Effect of the genetic structure and sex local Iraqi chicken and Brahman in some hematological treaties

Abstract

This study conducted in the Physiological Laboratory of the Department of Animal Production/College of Agriculture/Tikrit University, with the aim of finding out the effect of the genotype and sex of local chickens and Brahma chickens on some hematological traits. Used 24 blood samples, twelve samples from local chickens and Brahma chicken, with six samples for both sexes. After performing the hematological analyzes, the following results showed A significant effect of the genotype was observed in the TCH, HB, MCV and MCH. Moreover, it showed a significant increasing for domestic chickens compared to Brahma chickens. The total number of red and white blood cells did not significantly affect the genotype. Sex had a significant effect on most of the studied traits (HCT, HB, RBC, MCV, and, MCHC), where males significantly outperformed females. The interaction between genotype and sex had a noteworthy impact (p≤ 0.05) on most ofthe considered characteristics, and it by and large demonstrated a noteworthy diminish within the examined characteristics in female Brahma chickens compared to male and female residential chickens and indeed male Brahma. However, not effect in WBC count. From the results local chickens recorded to exceed expectations in most of the physiological characteristics and for both genders, the immune status of both genetic structure was rise to, and this may show the versatility of the Brahma chickens to the Iraqi airspace.

Effect of The Critical Period and Gene Silencing on Blood Cellular Traits in Local Chicken and Level of Welfare

“…Table (2) show in the heterophile cells (Het), the control treatment recorded a significant superiority under probability (P≤0.05) over the second, third, fourth, and sixth treatments, while it did not differ significantly from the fifth treatment [23]. In addition, the fifth treatment recorded a significant superiority under probability (P≤0.05) over the second treatment, and it did not differ significantly from the rest of the other treatments.…”

“…These lines depend on the color of the feathers and their distribution, as well as on the shape of the crest [1]. The occupation of Baghdad occurred in 2003, which resulted in the complete loss of these lines, and this prompted the officials in charge of that to return to selecting chickens close to those lines with important production specifications and other good qualities and trying to improve the production of those lines available [2]. The main problem in local chickens are the lack of egg production due to its fierce nature, which increases the secretion of stress and fear hormones, which 1252 (2023) 012141 IOP Publishing doi:10.1088/1755-1315/1252/1/012141 2 mainly affects reproductive hormones but it is distinguished by its ease of rearing and its tolerance to environmental conditions of heat and cold, and its resistance to diseases, and it has a breed that has the ability to resist stress [3].…”

Effect of habituation and gene silencing on blood biochemical traits in local chicken indicative of their level of welfare

“…Since the 1970s, the development and genetic improvement of Iraqi local chickens began with the aim of obtaining lines with high production e ciency, resulting in six genetic lines distinguished by their production and high adaptation to the Iraqi environment. (Ali et al, 2019).However, the occupation of Baghdad in 2003 resulted in the complete loss of these lines and has prompted a return to selecting chickens close to those lines with important production speci cations, and other good qualities, to improve the production of those lines now available (Taha & Hasan Aljumaily, 2021). The main problem with the local chicken breeds is their lack of egg production due to their erce nature (Abdul-Lateif & Abdulateef, 2012), which increases the secretion of stress hormones that affect their reproductive hormones.…”
