Coccidiosis is a widespread and costly intestinal disease in chicken and is caused by protozoan parasites of the genus Eimeria. Coccidiosis disrupts the morphology and function of the intestinal epithelium and negatively affects nutrient digestion and growth performance in broilers. Antioxidant drugs have traditionally been used to manage coccidiosis, but these compounds do not completely eliminate Eimeria infections. In addition, laws prohibiting the use and concern of consumers about the daily exposure of anti-coccidiosis compounds to animal feed have reduced their use. This has led to a greater emphasis on finding nutritional strategies to minimize the harm of Eimeria infection on the performance of broiler chickens. Oxidative stress due to increased production of reactive oxygen species in adverse environmental conditions and diseases are important factors in reducing the efficiency and health level of poultry especially in dense conditions. Coccidial infections reduce the level of antioxidant defense in patients and oxidative damage is a major contributor to disease-causing lesions. Therefore, enhancing the antioxidant system of chickens and avoiding oxidative compounds is important as a useful strategy in reducing disease wastes. Copper and zinc have antioxidant properties as a result of their catalytic function in the cytoplasmic enzyme superoxide dismutase. Therefore, different approaches, such as the inclusion of edible additives such as copper, can be effective.

In recent times, sport horses faced limitations in their choice of ration, social interactions, and mobility, which could predispose them to stress. There are mechanisms which could assist such horses to cope when facing such challenges, resulting in them performing repetitive behaviours, known as stereotypies. These stereotypies are considered as a threat to horse’s welfare. Stereotypic behaviors have been first observed during the weaning period, and it seems that weaning stress is effective in its occurrence. There are other contributing factors, which could result in this behavioural problem such as lack of fibre, forage scarcity, boredom, social isolation and limited workout. In order to prevent such behaviours, there are a number of physical and pharmaceutical intervention methods available; however, the majority of these methods by suppressing the natural stress modulatory mechanisms, could cause further distress and do not help to eliminate the cause of stereotypic behaviors. Therefore, it appears that improving husbandry practice by controlling and reducing stressful factors, is more efficient and less costly.

Nowadays, the number of livestock products in the world has increased, and this has led to strategies to increase the production of livestock products. The use of enzymatic biological methods to deal with feed-related problems has been the focus of nutritionists due to their low cost and environmental pollution. Solid and protected capsules to be used. Including cellulose enzyme, which is composed of three enzyme complexes (exoglocanase, endoglucanase and beta-glucosidase) and is responsible for digesting cellulose. The lignin-degrading enzymes are oxidases such as lacase and manganese peroxidase. Adding fibrolytic enzymes to the diet of Fresh cows increases milk production due to its positive effect on nutrient intake, digestibility, ruminal fermentation and microbial protein synthesis, and in the diet of growing beef, it stimulates feed intake and Its effects. They create a positive in ruminal fermentation. Also, the addition of enzymes to the diet of lambs increases daily weight and the ability to digest nutrients without affecting feed intake.

The general perspective of livestock and poultry breeding is being transferred to the digital era with high operational capacity, in which high-throughput technologies are utilized to boost the accuracy of phenotypic records collection and estimation of breeding values. Then, using advanced software and large computers, high amount of data is processed. The advent of NGS and the identification of SNPs along with new statistical methods for using this data to estimate the breeding value has led to the widespread use of genomic selection in dairy cattles and poultry. The development of data mining algorithms related to big data plays a significant role in estimating breeding values. A range of novel technologies, such as artificial intelligence, machine learning and deep learning, provide proper opportunities compared to traditional methods for examining economic traits with complex architecture. These approaches have made it possible to analyze large data sets and large genomic information in order to achieve desirable results. The purpose of this study is to provide a brief explanation of the new methods and novel technologies in animal sciences which are widely used in phenotype data collection and data registration in order to estimate accurate breeding values, in such a way as to lead to a digital future. Therefore, increasing the potential of big data analysis, along with new methods for recording phenotypic traits and estimating the breeding values, will dramatically augment genetic improvement.

Vitamins are very important in maintaining the health and functions of most living organisms. It is well known that vitamin deficiencies cause immune system disorders. Poultry vitamin requirements are usually determined under ideal breeding conditions. Because poultry are affected by various stresses in breeding halls, the need for vitamins to cope with stressors increases. The role of vitamins in improving bird performance during heat stress has long been studied. However, according to research, the amount of need for certain vitamins in heat stress conditions has not led to an absolute conclusion. Many poultry farmers not only use vitamin C during hot periods to prevent the harmful effects of heat on the emergence function, but also to improve the immune system, the quality of the final products produced, fertility and hatchability in flocks of broiler breeders. In poultry production, heat stress is defined as both acute and chronic. Acute heat stress refers to short and sudden, sudden periods of temperature rise, and chronic heat stress refers to long and slow periods of heat.

Bioinformatics is an interdisciplinary science that uses a combination of statistics, mathematics, and computer science to collecting, editing, recovery, data mining, and analyze biological macromolecules, including nucleic acids and proteins. Bioinformatics has four main general parts, which are Genomics, Transcriptomics, Proteomics, and Metabolomics. Genomics involves the study of the genome of individuals; That is, all studies, whether structural or functional, combine the two directly on DNA. Structural studies mean the detection of mutations or measurements of chromosome length and studies such as those of the DNA molecule itself. But in functional studies, the goal is to study the physiological function of the gene. In the transcriptomics section, the transcriptome or DNA-transcribed product, in other words, all the DNA-generated RNAs are studied. But because RNA has a very short half-life, it first converts it into a more stable molecule called cDNA (cDNA library) and then studies it. In this section, the main purpose of the study is to measure gene expression, but other actions such as identifying mutations as well as identifying new genes that were previously unknown can be performed with regard to recent advances in the bioinformatics basin. In the proteomics section, the proteome is the case for all the proteins produced by the expression of DNA genes, and in the metabolomics section for all the physiological functions that result from the expression of DNA genes, like all chemical reactions that take place in the body. The study is included.
