Abstract: The objectives of this study were to characterize the current dairy production system in Myanmar and assess the feasibility of establishing a genetic evaluation program for dairy traits using information from three traits collected by dairy producers. Phenotypic and pedigree data from 728 individual animals were provided by eight participating dairy herds located in the Mandalay Region, the Yangon Region, and the Shan State of Myanmar. Data were assessed for correctness, completeness, and genetic links among herds. Means and standard deviation (SD) for milk yield per day (AD), total lactation yield (TY) and lactation length (LL) were computed by farm and dairy production area. Most cows had their sire (63.0%), dam (66.2%), or both parents (57.6%) identified. Cows with records were 12.0% for AD, 47.8% for TY, and 13.6% for LL. Cow means and SD for the complete dataset were 10.91 ± 3.23 kg/d for AD, 2,319.10 ± 1,221.93 kg for TY, and in 273.02 ± 90.71 d for LL. Farm means ranged from 9.75 ± 5.12 kg/d to 12.75 ± 5.97 kg/d for AD, 2,165.18 ± 1,556.94 kg to 3,367.85 ± 183.92 kg for TY, and 224.88 ± 155.42 d to 345.50 ± 78.03 d for LL. Although insufficient for a genetic evaluation, the information provided by dairy producers in this study indicated that the basic infrastructure already exists. Thus, to develop a national genetic evaluation program, Myanmar needs to increase the number of participating dairy producers, herds and recorded cows, improve completeness and accuracy of individual animal phenotypic and pedigree records, enhance the genetic connections among herds and contemporary groups through the use of common sires, maintain accurate information of feeding, management, and health practices, provide training to personnel involved in tasks associated with the program, and promote the increase in productivity, profitability, economic viability, and sustainability of dairy cattle under an effective genetic evaluation and selection program.
