2014 sheep and lamb losses
February 20, 2015
Montana sheep and lamb producers lost 39,000 animals to weather, predators, disease and other causes during 2014, representing a total value of $7.3 million, according to a survey conducted by USDA, National Agricultural Statistics Service, Mountain Regional Field Office. The total number of sheep and lambs lost was 700 head less than last year, and the total value of inventory lost was 5 percent more than a year ago. The January 1, 2014 inventory was 220,000 head. The lamb crop for 2014 was 200,000 head. Lambs lost before docking during 2014 was 12,000 head.
Sheep and lamb deaths for 2014 amounted to 9 percent of the 2014 sheep and lamb supply (inventory plus lamb crop plus lambs lost before docking). The number of sheep and lambs lost to all predators totaled 16,400 head, up 200 head from last year. Lamb losses by all predators amounted to 13,400 head, up 1 percent from last year. The number of sheep lost to all predators totaled 3,000 head, up 100 head from a year ago. Predators caused an estimated $3.0 million in losses in 2014, up 6 percent from the previous year. Losses due to predators amounted to 3.8 percent of the 2014 sheep and lamb supply and 42 percent of all sheep and lamb deaths.
Coyotes remained the largest predator for both sheep and lambs. Coyotes accounted for 80 percent of the predator caused losses and 34 percent of all death losses in the state. The value of losses attributed to coyotes was $2.4 million. The total value of non-predatory losses was $3.8 million in 2014, compared with $3.7 million in 2013. Non-predatory losses accounted for 52 percent of all losses. The largest non-predatory cause of losses was due to weather conditions at 6,300 head. Sheep lost to non-predatory factors totaled 7,800 head, up 13 percent from 2013. Non-predatory lamb losses came in at 12,400 head, 1,700 head less than a year ago.
Lambs lost to unknown causes totaled 1,200 head, compared with 1,600 head last year. Unknown causes claimed 1,200 sheep, compared with 900 head last year. The value of sheep and lambs lost to unknown causes was at $463,800, up 5 percent from last year.
Methodology and Definitions
The sheep and lamb survey utilized multi-frame sampling procedures. The survey involved drawing a random sample from a list of livestock producers maintained by the USDA, National Agricultural Statistics Service, Montana Field Office. In addition, sheep producers living in a selected sample of area segments were interviewed. This procedure assures complete coverage of sheep producers by accounting for ranchers/farmers who may not be on the list. Sheep and lamb loss estimates published by the USDA include sheep losses for the entire year, but include only those lamb losses that occur after docking. This special report also includes an estimate of lambs lost before docking.
