Red meat exports. The study aimed to know the most important recommendations that appoint government agencies and the private sector in order to increase production and improve productivity. The study concluded that there is an inverse relationship with a significant and statistical effect between the exchange rate and the amount of meat exports by ٪77, while other factors b ٪23 are attributed to the fact that decreasing the value of the exchange rate ٪1 leads to an increase in the amount of red meat exports by ٪4. There is a statistically inverse relationship with the value of red meat exports by ٪ 31, while the other factors included in the random error limit are attributed by 69 percent to that devaluing the exchange rate by ٪1 leads to an increase in the value of red meat exports 3% The study recommended encouraging investment in the agricultural and animal fields, rehabilitating development and infrastructure projects, and working to raise the competencies of promotion and marketing, training and qualification of veterinary and production cadres.

This study was conducted in three localities of Al-Dinder, Abu Hajjar, Al-Dali and Al-Mazmoum, Sennar State, to study the effect of climate changes on the sorghum crop. This study aims to identify the concept of climate changes, identify the elements of climate, identify the causes of climate changes, measure the extent of farmers' knowledge of climate changes and know the impact of climate changes on the corn crop. * The data was analyzed statistically using the SPSS statistical analysis program, which showed that the degree of Temperature does not affect planting dates, life cycle and crop structure, crop production and crop quality, as there is a clear effect of the amount of rain and its impact on planting dates, life cycle and crop structure, crop production and crop quality, and that the fluctuation of rain affects planting dates, production and crop quality. Also, the beginning and end of the rainy season affects the planting dates, and the production and quality of the crop. The study reached recommendations addressed to the various governmental institutions, civil organizations and administrations, and the community. The most important of these recommendations is the development of drought-resistant varieties with good quality specifications, the establishment of a meteorological station in the study area, the introduction of scientific methods Modern agriculture in the study area, strengthening and expanding platforms, infrastructures and tools to prevent emergencies a related to sorghum caused by climate change.

The study conducted in Bayara Meadow, located in Essuki town at sinnar, state. Sudan. It sits at the eastern bank of the Blue Nile (E:03352351 N: 1319302) Which considered as breeding, roosting sites for many bird’s species. The total area of it is 35,862 km2 (129m length, 278m long). The study extended from 28/7/2022 to 7/11//22022 during the rainy season, first period from 28/7/2022 to 7/9/2022, the second period from 12/ 10/2022 to 20/10/2022 the last period from 24/10/2022 to 7/11/2022. The total area was divided to four plots of (3225 length 278long) total area 8965.5 M2. The direct count method is used to count the birds number and try to monitor its behavior, feeding roosting site and other activities on the morning and evening. The morning count begin at 6 o’clock till 10 o’clock while the evening watching begin from 4:00 o’clock to 6:00 o’clock. Equipment used for data collection are a pair of binoculars (8X50 magnifications), Telescope - Swarovski (660 - 940), digital still camera for documenting, data recording sheets, notebook The bird was observed, counted if inside each block only and notes were taken directly about activities pattern.

This study was conducted to investigate the effect of feeding graded levels of Rhynchosia Minima (0%, 5%, 10%) on the performance and external body measurements of Sudanese desert goats. Twenty seven goat kids less than one year old and of initial body weight of (8.14 kg) were utilized. These kids were divided into three experimental groups of nine kids each. Three isocaloric (12.2 Mj/kg) and isonitrogenous diet (17%) containing graded levels of Rhynchosia minima was offered to the kids groups. Results revealed that addition of Rhynchosia minima to the ration significantly (p<0.05) increase the feed intake and the body weight gain. Also feed conversion efficiency was significantly (p<0.05) influenced by adding Rhynchosia minima to the ration. As far as external body measurements was concerned, back length and thigh circumference was significantly (p<0.01) increased by increase inclusion of Rhynchosia Minima in the ration while heart girth was significantly (p<0.05) increased by inclusion of the tested material.
