A cross-sectional study with a random cluster sampling design was carried out to estimate the seroprevalence of bovine herpesvirus type 1 (BHV-1) in non-vaccinated dairy herds in Hamedan province, west of Iran. Simple random sampling was used for selection of cattle in each herd. Informative data about each herd and selected animals were recorded by the farm manager in a provided questionnaire....

to test the effect of culling herd life from the breeding goal function, 4 different selection indices were established as: index 1: using milk production (milk), fat percentage of milk (fat%) and rear udder height (ruh); index 2: using milk , fat% and fore teat placement (ftp), index 3: using milk, fat% and fore udder attachment (fua); and index 4: using milk, fat%, ruh, ftp and fua) under two...

the aim of this study was to design the base breeding plan in sistani cattle by using of stochastic simulation. for this purpose, three population size (500, 1000, 2000 heads), three levels of herd number (5, 10, 20), two levels of selection intensity (high and low) and two levels of mating method (random and minimum co-ancestry) were combined together and in total 36 scenarios were compared fo...

the objective of this study was to determine the optimum replacement strategy using dynamic programming for dairy herds in fars province. a dairy cow is kept several lactations for milk production in the herd. after spending several lactations, milk production gradually begins to decline, while animal health problems rises simultaneously. so one of the most important management decisions of dai...
