Sheep possess desirable characteristics for farmers such as resistance to disease, good acclimation to environmental fluctuations, and endurance to extreme weather. This may, in part, be due to hematology characteristics and various types of hemoglobin that interact differently to external changes; displaying various reproductive ability in certain environmental conditions. This review aims to investigate the effect of hematology parameters and hemoglobin types on the adaptation and reproductive performance of sheep. Hematological parameters are useful tools for the detection of adaptation and physiological traits of these animals. The reproduction of sheep has depended on the ability of each type and breed to acclimate to different environmental conditions. In addition, hemoglobin types have also been correlated with the environmental adaptability and physiological traits of sheep. Thus, the present review provides useful information on the association of hematology parameters and hemoglobin types in sheep with adaptation and reproductive performance, and could be used as vital tools that help in determining the species or breed of sheep that are more adapted to certain environments or have more reproductive potential.

Using magnetic technology has shown major potentials in different fields especially agriculture. Two experiments were conducted to investigate the using of magnetic technology application in local quail house and hatchery on productive and physiological traits under heat stress condition. Results revealed that quail when served 0.2 T magnetically treated water (MTW) were significantly (P≤0.05) better in most productive, reproductive characteristics in the 1st experiment: eggs production, water consumption, egg weight, shell strength, estrogen conc., also improved FCR in females, all semen quality and testosterone conc. in males. Also, total RBCs count, thrombocyte, blood pH, blood viscosity, plasma viscosity, blood iron (Fe), copper (Cu), calcium (Ca), thyroxin hormone and total count of Lactobacillus spp. in small intestine. However, reduction in dead sperm, abnormal acrosome, corticosterone conc., body temperature, blood clotting time, E. coli and fungi counts in both sexes. In the 2nd experiment using of magnetic technology on embryonic development traits of local quails incubating eggs that collected from experiment 1 were significantly (P≤0.05) higher in the most characteristics at the group of 0.2 T MTW as fertility, hatchability, chicks weight, immune status of hatched chicks. While reduction in dead embryo and heterophil-to- lymphocyte (H/L) ratio. Finally, the results of 0.2 T MTW achieved superiorly gains compared with the other groups.
