The poultry industry has gained significance all over the world due to providing economical, healthier food than red meat and other protein sources. Food and Agriculture Organization (FAO) estimated 103.5 million tons of global chicken meat production annually in 2012, which contributed about 34.3% to global meat production. Generally, poultry farming has performed a leading role in the livestock sector in some others regions of the world. But poultry farming system is affected by both environmental and disease stress. Various viral, bacterial, parasitic and fungal diseases affect the production performance of birds by affecting respiratory system, reproductive system, immune system, gut system and central nervous system which, in turn, cause loss of appetite, reduction of body weight, drop in egg production, air sac infection, coughing, sneezing, difficulty in breathing, septicemia (blood stream infection), paralysis of neck, wings and legs, enteritis (intestinal infection), bloody diarrhea, immunosuppression and higher mortality which cause huge economic losses in poultry industry. Therefore, there is need to control poultry diseases. Our aim was to provide a pictorial guidebook on poultry disease; diagnostic techniques and their effective treatment which may help to diagnose the viral, bacterial, parasitic and fungal infection. This may provide an important guideline to identify and minimize diseases before their incidence.
Contribution/ Originality
Our main objective was to provide a pictorial guidebook on poultry disease to avoid the production losses facing the global poultry industry. Several reports have theoretically addressed on poultry diseases but there is lack of sufficient data related to pictorial guidebook on avian diseases. Therefore, this study is one of very few studies which have documented on poultry diseases as a pictorial guideline; diagnostic techniques and their potential treatment.

Obtaining good zootechnical performance in broiler chicken farming requires continuous and regular zootechnical and sanitary monitoring throughout the breeding period to increase its rentability. Our work carried out at the level of private broiler chicken farming in Eastern Algeria with the objective of comparing zootechnical performance during the breeding period with that obtained under the optimal conditions of strain ISA 15. Whose controlled and compared parameters show: a very high mortality rate- a very low weight evolution- a higher consumption index.

Zinc (Zn) has antibacterial and antifungal properties, so, it is being widely used in food and pharmaceutical industries. Transition metal especially Zn deficiency has deleterious effects all over the world due to wide consumption of Zn deficient food byproduct. Several studies have reported that transition elements especially Zinc deficiency affects the endocrine and reproductive system. This overview comprises the information about negative effects of Zn deficiency on reproductive system of male rat and their possible outcomes. Scientific studies indicated that Zn deficiency severely affects the reproductive physiology of male rats. Zn deficiency suppresses the function of male rat testes inclosing spermatogenesis and steroidogenesis by reducing the production of androgen hormone. In addition, Zn deficient rats also indicated testicular atrophy, primary and secondary spermatogonial stem cells disruption, lower number of sperm cells count, sperm quality, motility, viability, enhance in oxidative stress, inhibition of Testosterone (T) level which, in turn may cause infertility. The different consequences in animal models by zinc application are dose and duration dependent. Several studies propose that both higher and lower Zn concentration can effects the rat reproductive function. Therefore, the available outcomes revealed that Zn deficiency might have significant influence on luteinizing hormone and follicle stimulating hormone affecting the sperm physiology and histology in certain tissues.
Contribution/ Originality
This recent study has contributed significant scientific information on a particular subject area “Zinc deficiency”. A lot of reports have discussed the Zinc and its effects on human but there is lack of sufficient data related to Zn deficiency on reproductive profile of male rats. Therefore, this study is one of very few studies which have documented that Zinc is necessary in male reproductive system of human and animals. On the other side, it is recommended that optimum amount of Zinc supplementation should be used to avoid the deleterious effects on male reproductive physiology.
