“…Turkey is included in the risk group of countries in terms of the potential effects of global warming due to increases in extreme values of eastern Mediterranean. In Turkey will be affected by the negative aspects of global warming such as the weakening of water resources, forest fires, drought and desertification, and ecological deterioration dependent on them (Yetisgin and Sen, 2020). According to Turkey's 2019 data, the total greenhouse gas emission was 506.1 million tons CO2.…”

Climate change is seen as a significant threat to the sustainability of many species, ecosystems and livestock production systems in many parts of the world. With the rise of average temperatures at the global level, a number of effects occur. These effects lead to different changes in climate, regionally and globally. Livestock sector in Turkey is the leading sector that is most affected by the global climate change due to the predomination of rural economic structure and industries based on developing livestock breeding. Health and welfare in animal production are an integral part of environmental sustainability. Extreme events and seasonal fluctuations affect the welfare of the animals and cause a decline in yield and reproductive performance. Sheep and goat are animals that can make the best use of pasture and use it in every season of the year. In addition to the effects of climate change on ecosystems, it is inevitable that it will create important problems on the natural resources that form the basis of animal production. Climatic characteristics such as temperature and precipitation patterns have a significant impact on the availability of pasture and other resources throughout the year of animals. In this study, it was aimed to reveal the effects of climate change on animal husbandry and especially on sheep and goat breeding.

One of the projected effects of climate change is a reduction in rainfall in certain regions of the world.Hence, the agricultural and livestock sectors will have to cope with increasing incidences of water shortage whilst still maintaining productivity levels to feed an ever increasing global population. This short communication reports on the effect of a two week water stress on Pelibuey sheep in Cuba. Three treatments were compared viz. supply of water ad libitum; water supplied once every 3 or 6 d. Following exposure to the water stress, the results showed no changes in sheep body weight or rectal temperature. However, respiration frequency was affected with water stress causing a reduction from 23.3 to 13.3 respirations per min in control and water deprived animals, respectively. Furthermore, there was evidence for hemoconcentration in response to water stress (levels of hemoglobin increased from 9.2 to 13.1 g L -1 and hematocrits from 27.6 to 39.3% in the control group and animals restricted to water once every 6 d.The imposed water stress was also evident in the reduction of lymphocytes (from ±63 to 43%), and in increase of neutrophils (from approximately 38 to 54%) and leukocytes (from 3133 to 4933 per mm 3 ).The results indicated a decline in the levels of antioxidants, i.e. SOD (SOD from approximately 13 to 10 U mg -1 protein and CAT activity from 23 to 9 U mg -1 protein. To the best of our knowledge, this is the rst report on the response of Pelibuey sheep to short-term water shortage stress under Cuban environmental conditions.

Malnutrition of pregnant beef cows and the impact on passive immunity transfer to calves

Nutritional management in rangeland beef cattle systems prioritises optimal body condition scores at calving for improved fertility and reproductive success. However, this focus often overlooks short-term dietary deficiencies before calving, which can lead to adverse outcomes for neonatal calves. This review explores the effects of beef cow malnutrition during the periparturient period on colostrum production, lactation onset, and passive immunity transfer to calves. Additionally, it discusses the long-term impact of such malnutrition on the offspring. By understanding how nutritional interventions affect the transition from gestation to lactation, it becomes possible to enhance calf health and survival in arid tropical environments. Commonly occurring short-term dietary restrictions, particularly protein deficiencies, can disrupt the hormonal equilibrium, resulting in reduced colostrum volume and quality, hindering calf growth and increasing mortality risks. Furthermore, dietary restrictions during this period affect critical physiological processes such as mammary gland blood flow and fetal small-intestine development. The review explores how these constraints influence colostrum production and immunoglobulin absorption by neonatal calves. Additionally, it highlights the significance of addressing other common nutrient deficiencies such as phosphorus and water and investigates the potential benefits of supplementing microbial products to enhance rumen function and protect cows from inflammation. Ultimately, addressing malnutrition during pregnancy is essential to prevent negative impacts on offspring performance, including alterations in carcass composition and muscle marbling. Consequently, cattle producers who aim for superior muscle marbling in the carcass by using costly genetics should give priority to enhancing nutritional programs for late-pregnant cows. In conclusion, a comprehensive understanding of the effects of malnutrition during the periparturient period on colostrum production, passive immunity transfer, and overall calf health is crucial for developing effective nutritional interventions that improve colostrum production, passive immunity transfer, and overall calf health in rangeland beef cattle systems.
