Poultry genetics and reproduction
Poultry breeding has been one of the most impactful advances in the last 100 years. The role that improved global production of eggs and poultry meat have in reducing global hunger and food insecurity is difficult to overstate. The vast majority of these improvements have come from genetic selection for improved feed efficiency, along with streamlining of the overall production system, and better understanding of poultry nutrition. While the industrial approach to poultry production has created a highly consistent and dependable food source the world over, several problems threaten the long term sustainability of this model - including musculoskeletal and metabolic disorders, welfare concerns, and the need to adapt to a changing climate. Researchers in poultry breeding and genetics utilize quantitative, population, and molecular genetic techniques to help understand the effects of selection for economically important traits and enhance genetic performance through changes in environment and management strategies.

Breeding is crucial in livestock management, ensuring continuous production and maintaining genetic excellence. Better breeding results mean healthier offspring, higher birth rates, and enhanced herd or flock health. Nutrition is pivotal for breeding success in most livestock. Balanced diets, rich in essential vitamins, minerals, and nutrients, help animals achieve their full reproductive potential. We present IntelliOpt, the solution for effective nutrient utilization...

As part of the practical section on poultry reproductive system anatomy for third-year students at the College of Agricultural Studies, Sudan University of Science and Technology, we procured a spent layer hen from a local market in Khartoum North. The objective of the dissection was to examine the reproductive system, which is composed of the ovary and the oviduct (Fig. 1). The ovary is responsible for the development of ova or yolks. When an ovum has matured, it is released from the...

Artificial insemination is currently a necessary and exclusive means of breeding turkeys in large farms (Di Iorio et al., 2020; Slowinska et al., 2018). For optimal fertility outcomes, breeders must focus not only on the insemination itself, but also on the quality of collected semen. The culture medium is one of the main factors influencing semen quality and turkey spermatozoa in in vitro conditions. The aim of the study was to evaluate the impact of selected additive substances with...

Introduction Commercial egg-laying chickens reach sexual maturity (begin laying eggs) at about 16-18 weeks of age. At 30-32 weeks of age, they attain their peak egg production. During the first year of laying, hens maintain a high laying rate (> 90%) (an average hen lays > 320 eggs), and subsequently, egg production gradually drops, indicating a decrease in ovarian function. The ovulatory cycle in hens lasts about 24-26 hours, depending on age (e.g., shorter in young...

Conventional broiler (meat) chickens reach a final weight of 6.6 lbs (3 kg) in approximately 40-44 days. Across their lifetime, these fast-growing birds gain an average of 68-75 g per day, with daily gain increasing with age (Aviagen, 2022; Cobb, 2022). With their fast growth, however, they...

INTRODUCTION In the worldwide poultry industry, egg-laying production efficiency is a significant economic trait. Excellent productivity is measured by the number of ovarian follicles heading for ovulation and the efficiency of the oviduct to convert the ova into a hardshelled egg. But to increase number of ovarian follicles many factors are involved like Nutritional factors, Pathological factors, Managemental factors and Climatic factors. Before going to topic of available...

The parents of broilers are defined as broiler breeders. In contemporary poultry industry practices, there are many selection criteria for broiler breeders. Beyond selecting for future broilers, maximizing broiler breeder characteristics (i.e. reproductive success) is also important. In essence, we are not only selecting for...

Background & Objectives Korean Native Chicken (KNC) market field keeps enlarging by the increasing consumer interest on KNC due to the desired flavor, texture and healthy value of its meat. Despite the demand for native chickens increasing due to the requirement for diversification of consumers, making good KNC layer species to meet the demand of consumers is very limiting. It is necessary to secure and maintain the various the pure-line in order to improve production...

INTRODUCTION The production performance of laying hens during their late laying period is rapidly decreasing. This late period represents nearly 50% of the whole laying period, and laying hens are generally eliminated at about 500 days of age. However, laying hens still maintain a laying rate of 60-70% at this time; therefore, the production performance of flocks during this late laying period directly affects the economic benefits of farmers. Therefore, prolonging the...

INTRODUCTION Amino acids (AA) and crude protein (CP) intake during the rearing phase in broiler breeders have demonstrated to affect body composition and reproductive performance in the laying period (Joseph et al., 2000; Ciacciariello and Tyler, 2013; van Emous et al., 2013, 2015a, 2015b). Modifications of these nutrients added up to the adjustment of feed allocation may alter BW (van Emous et al., 2013; Soumeh et al., 2018), organ development (Lesuisse et al., 2017), egg...

The breeding performance is count upon the reproductive status of birds. In current poultry industry there are numerous challenges for reproductive competency. Many of these problems originated from upgrading body growth rate and egg production traits in poultry; which results weakening in reproductive characteristics. The continuous trend towards high yielding and fast growing birds ensuring that task of managing the breeder stock will not be easy more. Males...
