Throughout the second half of the nineteenth century and into the early part of the twentieth, American agriculture was expanding and improving under the influence of growing demand, the westward movement, mechanization of farm operations, and scientific farming developments. Under these influences, yields and labor productivity in field crops generally increased. Until recently, however, little has been known about the course of productivity change in specific agricultural activities during the nineteenth century. Dairy production was an important component of the American farm economy, accounting for about 16 percent of U.S. farm output at the beginning of the twentieth century and approximately 14 percent of gross income from farm production in 1910. Changes in dairy yields during the period 1850–1910 have been analyzed previously. The purpose of this article is to estimate labor input time, to measure the change in average labor productivity in U.S. dairy farming, and to examine the economic implications of this change, thus extending the analysis to another component of the dairy production function. The necessary data were estimated with techniques that utilized available fragmentary data in conjunction with information in literary material.

Based on six sets of witnesses' accounts from the North of England and London over the period 1760 to 1830, new estimates of male labor input during the Industrial Revolution are derived. I present a new method of converting witnesses' activities into estimates of labor input, and derive confidence intervals. Working hours increased considerably. Moderate gains in per capita consumption during the Industrial Revolution have to be balanced against this decline in leisure. This adds further weight to pessimistic interpretations: I calculate that consumption per capita, adjusted for changes in leisure, remained essentially unchanged between 1760 and 1830.

peer-reviewed ; With the cessation of milk quotas in the European Union, dairy herd sizes increased in some countries, including Ireland, with an associated increase in labor requirement. Second to feed costs, labor has been identified as one of the highest costs on pasture-based dairy farms. Compared with other European Union countries, Ireland has historically had low milk production per labor unit; thus, optimization of labor efficiency on farm should be addressed before or concurrently with herd expansion. The objective of this study was to quantify current levels of labor input and labor efficiency on commercial pasture-based dairy farms and to identify the facilities and management practices associated with increased labor efficiency. Thirty-eight dairy farms of varying herd sizes, previously identified as labor-efficient farms, were enrolled on the study and data were collected over 3 consecutive days each month over a 12-mo period, starting in May 2015 and finishing in August of 2016. This was achieved through the use of a smartphone application. For analysis purposes, farms were categorized into 1 of 3 herd size categories (HSC): farms with <150 cows (HSC 1), 150–249 cows (HSC 2), or ≥250 cows (HSC 3). Overall farm labor input increased with HSC with 3,015, 4,499, and 6,023 h worked on HSC 1, 2, and 3, respectively. A higher proportion of work was carried out by hired staff as herd size increased. Labor efficiency was measured as total hours input to the dairy enterprise divided by herd size. Labor efficiency improved as herd size increased above 250 cows with 17.3 h/cow per yr observed for HSC 3; labor efficiency was similar for HSC 1 and 2, at 23.8 and 23.3 h/cow per yr, respectively. A large range of efficiency was observed within HSC. The labor requirements had a distinct seasonal pattern across the 3 HSC with the highest input observed in springtime (February to April) primarily due to calving and calf-care duties, milking, and winter feeding. The lowest input was observed in wintertime (November to January) when cows were dry. Particular facilities and management practices were associated with efficiency within certain tasks, the most notable in regard to milking and winter feeding practices. Additionally, the most efficient farms used contractors to perform a higher proportion of machinery work on farm than the least efficient farms.
