The effect of conjugated linoleic acid (CLA) feeding on growth performance and fatty acid profiles in thigh meat of broiler chicken was investigated using meta-analysis with a total of 9 studies. Overall effects were calculated by standardized mean differences between treatment (CLA fed) and control using Hedges's adjusted g from fixed and random effect models. Meta-regression was conducted to ...

Primary and further processing of poultry is a multibillion dollar industry in the US. The majority of poultry raised and commercially processed in the US is composed of chickens, turkeys, and ducks, with more than 9 billion birds processed in 2010 (Table 24.1). Total retail product weight exceeded 58 billion pounds, with an estimated retail value of $100 billion. The general process of turning...

The potential of extracts prepared from seeds of three citrus species (orange, lemon and grapefruit) to stabilize lipid oxidation of cooked and raw broiler meat under refrigeration storage was evaluated and compared with butylated hydroxyl anisole (BHA), a synthetic antioxidant. The citrus seed extracts were separately applied at a rate of 1.5% of the weight of the meat. There was a negative co...

High temperature is one of the key environmental stressors affecting broiler production efficiency and meat yield. Knowledge of broiler self-regulation mechanisms under heat stress is important for the modern scale of poultry breeding. In the present study, the SWATH strategy was employed to investigate the temporal response of the broiler liver to heat stress. A total of 4,271 proteins were id...

Poultry meat has a high risk of contamination during its processing. Storage temperature, type of packaging, and types and numbers of psychrotrophic bacteria are the major factors determining the spoilage of poultry meat. Before packaging, poultry carcasses are chilled by air or water currents in commercial slaughterhouses. The packaging material and methods are other factors influencing the sp...

The influence of Moringa oleifera (MO) leaf extract as a dietary supplement on the growth performance and antioxidant parameters was evaluated on broiler meat and the compounds responsible for the corresponding antioxidant activity were identified. 0.5%, 1.0%, and 1.5% w/v of MO leaf aqueous extracts (MOLE) were prepared, and nutritional feed supplemented with 0%, 0.5%, 1.0%, and 1.5% w/w of MO...

The objective of this project was to examine the diversity of breast meat composition and quality traits among unique resource populations. Birds from 5 groups (inbred Leghorn, inbred Fayoumi, commercial broilers, F5 broiler-inbred Leghorn cross, and F5 broiler-inbred Fayoumi cross) were utilized. Contemporary stocks (broilers, inbreds, and crosses) were grown in a single house but in separate ...

The objective of this study was to estimate the genetic and environmental parameters for carcass, carcass part, and organ weights in a paternal strain of broiler chickens that was selected mainly for body weight at 42 days of age (BW42) to provide support for poultry genetic improvement programs. A total of 1448 chickens were used that resulted from the expansion of a pure paternal strain named...

Dietary nutrients play a significant part in determining growth rate and meat yield. It is known that the compositions of protein and total amino acids of meat are invariable by feeding treatments, hence the meat taste is considered to be invariable. However, the relationship of taste components of meat with nutrients is not fully elucidated, and there have been few reports on the effect of fee...

In this paper, authors summarise studies refferering to enrichment of breast and thigh muscles with carnosine that has an important function in physiological processes. Research shown improves quality chicken meat. By adding amino acids β-alanine L-histidine chickens’ feed, synthesizes skeletal muscles, brain, heart muscle olfactory receptor cells. It been determined the content depends on type...
