“…The results also showed that there were statistically significant differences in the percentage of shell weight, as the second treatment outperformed the rest of the treatments. The results agreed with [24,25], who reported that adding methionine to low-protein diets had a positive effect on egg shape index, egg specific weight, and shell weight ratio while no significant differences appeared in the specific weight of the eggs of experimental treatment birds.

This study aimed to determine effect of various levels of protein, with two formulations and herbal sources of methionine and lysine. and synthetic threonine on serum biochemical properties, egg quality traits and egg chemical composition of 160 45-week-old Lyman Brown hens. It was randomly distributed to 8 treatments with five replications in (cages in the battery system), each repetition containing four birds, and the food treatments were, T1: basal diet (control) that contained 16.32% Cruz Protein (CP) with Synthetic 0.41% Methionine (S. T3: Basic Diet (16.18% CP) with (0.42% S.Mthionine), (0.05% Herbal Lysine: HL) and (0.106% S.Therionine) T4: Basic diet (16.18% CP) with (0.42% H.methionine), (0.05% lysine) and (0.106% threonine), T5: Basic diet (15.45% CP) with (o.42% S.methionine), 0.12% S.Lysine) and (0.116% S. threonine) T6: basic diet (15.46% CP) with (0.42% H.methionine), (0.045% H.Lysine and S. threonine), T7: diet Basal Diet (15.12% C.P) with (0.148% S.methionine, (0.150% S.lysine) and (0.130% S.thrionine), T8: Basal Diet (15.12% CP) with (0.148% H.methionine), (0.150% H.lysine) and (0.130% S.thrionine). The results of the statistical analysis in this experiment showed that there were no significant differences in the rate of egg production, the rate of egg mass, and the feed conversion coefficient, while significant differences were found in the rate of egg weight, the rate of feed consumption, and the rate of conversion of each of Protein, methionine, lysine and threonine.

“…After absorption, amino acids are assembled and metabolized to form proteins that are used to build different body tissues. Studies indicated that providing high protein and energy-rich diet to pullets in their growth and egg-laying phase showed positive effects on egg mass and yolk weight (Babiker et al 2011).…”

Nutraceuticals have gained immense importance in poultry science recently considering the nutritional and beneficial health effects of their constituents. Besides providing nutritional requirements to birds, nutraceuticals have beneficial pharmacological effects, for example, they help in establishing normal physiological health status, prevent diseases and thereby improve production performance. Nutraceuticals include amino acids, vitamins, minerals, enzymes, etc. which are important for preventing oxidative stress, regulating the immune response and maintaining normal physiological, biochemical and homeostatic mechanisms. Nutraceuticals help in supplying nutrients in balanced amounts for supporting the optimal growth performance in modern poultry flocks, and as a dietary supplement can reduce the use of antibiotics. The application of antibiotic growth enhancers in poultry leads to the propagation of antibiotic-resistant microbes and drug residues; therefore, they have been restricted in many countries. Thus, there is a demand for natural feed additives that lead to the same growth enhancement without affecting the health. Nutraceuticals substances have an essential role in the development of the animals' normal physiological functions and in protecting them against infectious diseases. In this review, the uses of amino acids, vitamins and minerals as well as their mode of action in growth promotion and elevation of immune system are discussed.

“…Thus, in this period, the quality of the feedstuffs is of great importance. Dietary energy level is not the first determining factor to affect the laying performance ( Babiker et al., 2011 ), but higher energy level can increase the body weight at the onset of lay ( Hussein et al., 1996 ). Although there are some studies showing that high level of dietary apparent metabolizable energy can improve laying performance ( Bornstein and Lev, 1982 ), it is agreed that energy should be considered on the basis of reasonable protein supply, or be dealt with using statistical modeling with protein ( Kuhi et al., 2012 ).…”

World egg production and consumption have been increasing for the past decades. Traditional strategies in poultry nutrition have made vital contributions to this great growth in quantity. However, current global issues should be considered in modern egg production such as growing populations and food security, food safety and quality, limited resources and environmental problems. The development of knowledge of poultry nutrition and modern biotechnology provides novel nutritional approaches to closely fit the requirement of pullets and laying hens, which will consequently decrease the nutrition excretion and maintain the lower cost of feed. Nutrition has also been widely accepted as a strategy to influence health and diseases of laying hens. The maintenance of good health is an important prerequisite for improving productivity and egg quality. In addition, there are many measures and strategies for minimizing the incidence of egg defects and providing a choice of lifestyle to enhance human health. This paper reviews current research progress on developing innovative technologies and strategies to maximize animal health and performance, improve the quality of egg products and minimize pollution caused by poultry production.
