“…The complexity of genetic capabilities of those breeds and the non-genetic factors including the management practices, climatic condition and fodder availability determines the amount of milk production. Climatic parameters include maximum and minimum temperature, relative humidity, wind speed, solar radiation, number of hours of sunshine, precipitation and elevation which affect metabolic activities and productive and reproductive gene expression of cattle (Bull, 1986).…”

Dairy farming is emerging as commercial enterprise and milk as the part of dietary food but the milk productivity of the cattle varies with the variation in climatic factors. So, breed selection plays imperative role on maintaining productivity and adoptability in different environments. Holstein Friesian and Jersey being the temperate breeds with high milk producing capacities could not perform well on the tropical and sub-tropical region. With proper feeding, Holstein has higher milk yield and low-fat percentage than Jersey. Milk yield varies by 2.58% in Holstein and 2.09% in Jersey cow with the change in climatic factors (minimum temperature, relative humidity and solar radiation). In hot areas, both breeds suffer from heat stress showing low feed intake, higher body and rectal temperature, high respiration rates and high heart beats. Holstein has high increase than Jersey in rectal temperature and heart beat by 0.550C and 15.4 inhalations/min respectively which shows Jersey are more heat tolerant than Holstein. It is due to the larger heat dissipating area, short and light hair, lighter body coat and thin fat. Heat stress can be managed by providing shade, nutritious feed and genetic improvements. As the climate change is emerging, it can affect cattle in tropical regions even more in near future. To overcome this future challenge, further research and study must be done for the proper management of Holstein and Jersey in stress condition and heat tolerance breed must be developed by genetic improvement.

Affected by climate change and high‐intensity human activities, the precipitation series is characterized by nonlinear complex fluctuations. In order to accurately quantify the precipitation complexity, the complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) method was introduced to address the shortcomings of the traditional multifractal detrended fluctuation analysis (MFDFA), and the CEEMDAN‐MFFA method was proposed to explore the spatiotemporal variability and possible causes of precipitation complexity in Northeast China (NEC). The results showed that the traditional MFDFA method generally overestimated precipitation complexity. However, the CEEMDAN‐MFFA method improved the accuracy and reliability of precipitation complexity analysis. Daily precipitation series in NEC were characterized by multifractal with high uncertainty and anti‐persistence. The lowest precipitation complexity was 0.573, which appeared in Qian'an, Jilin Province, and the highest precipitation complexity was 1.108, which appeared in the Boketu, Inner Mongolia. The cities with high complexity of daily precipitation are sporadically distributed in the three provinces of Heilongjiang, Jilin and Liaoning. The average complexity is ~0.892, accounting for 22.5% of the total administrative districts. The complexity of daily precipitation showed a statistically insignificant downward trend with time. The precipitation dynamics structure in the southeast and northwest of the study area was complex, and the precipitation was less predictable than other regions. However, the precipitation dynamics structure was relatively simple and the precipitation was easily predictable in the northeastern, central and southwestern regions. Elevation, topographic relief, changes in water area, forest area and agricultural production were the main influencing factors for the differences in precipitation complexity. Results also revealed that increasing the area of forestland by means of protecting and breeding forests, via regulation of the forest ecosystems to alleviate the complex precipitation process will become a reliable approach to cope with nonstationary precipitation.
