The number of animals is one case of that problem. Different estimates of the number are existed due to different agencies estimating at different methods in data collection and processing. The recent study is dianing with methods of estimating number of BufIalos and Cows in the Egyptian Agriculture. The study is aiming to analysa the methods of estimating ,number of animals and judge their efficiencies . It used secondary data, and primary data which was collected in the Agricltural Economics . Research Institute (AERI) , Ministry of Agriculture. Analysis of variance and regession analysis were used to achieve the study goals . The study contained for chapter , the first included the study general frame , problem , objectives , data types and sources, methodolgy and review of literature. The second sbapter concerned with the recent situation of large rumerant structure. The study showed that the number” of cows was estimated at 2.907 thousand, 2729 of them is local, 81 is foreign, and 97 is mixad. The number ofbuffalos reashed to about 3.32 million head in the 1990/91 agricultual census , The governorates ramking showed that Behera is first in holding COWS, Dakahli in b,u,f~falos and Qena in sheep and goats and camels . . ” The third chapter reviewed the methods of estinating livestock numbers . The methods are agricultural census , complete enunoration , Sampling techniques , regression analysis, and growth rates between two agricultural censuses . The study proR:d that most of these methods had its -)- .1 - iQS disad vantages which make it very difficult to be used . It was bvious that using sampling techniqus is more reliable since they have less error and cost, besides it could be applied yerly . The fourth chapter explained how the data coilected by a sample could be used to get the estimates of the animal number . The data alse was used to get more quantitative information such as the relationship between the number and some other variables, then it could be used to estimate the livestock number . -2- |
