Tie Stall Dimensions for Dairy CowsTable of Contents
ConceptsKnowledge of cow measurements and their space requirements is necessary to design stalls. Stall dimensions must be appropriate for standing, lying, rising and resting without injury, pain or fear. Stalls must meet the needs of the cow and the caregiver. Cleanliness is an important consideration. This document describes cow dimensions, space requirements and tie-stall dimensions for modern Canadian Holstein cows. Cow DimensionsDue to variation in cow size between and within herds, the first step in planning stall size is the measurement of Lactation 1 and mature cows in your herd. For tie stalls, it is common to build more than one size of stall. Therefore, measure a sample of the small, medium and large cows. Rump heights and hook-bone widths are useful measures to estimate several other body dimensions. Since several body dimensions are proportional, ratios provide reasonable estimates of dimensions for calves, heifers or other dairy breeds. It is becoming common to build stalls sized for Lactation 1 heifers, milking cows and dry or special-needs cows, in recognition of variation in cow size and needs within a herd. A barn with one stall size poses several challenges to both management and cows. Stall and cow cleanliness, labor, mastitis, foot diseases and cow comfort are issues to consider in choosing tie-stall sizes. Figure 1. Variation in cow size within and between herds highlights the need to measure your cows before choosing stall sizes.
Figure 2. Several cow measurements taken on standing cows are useful for building stalls. Other essential measurements are imprint length and imprint width of resting cows.
Table 1 shows measurements of mature Canadian Holsteins at a local dairy herd and some calculated proportions. For example, mature cows had a rump height of 60 inches, a nose-to-tail length of 8.5 feet and a hook-bone width of 25 inches. Their weight exceeded 1,550 pounds.
UBC research showed a 1350 lb cow uses 118 in longitudinal space and 43 in lateral space when lying. Space RequirementsObservations of cows freely lying and rising reveal that a mature Canadian Holstein cow uses 102 x 52 inches of living space and another 20 (16-24) inches of open forward space for lunging motions. Several cow dimensions that define this living space include those
shown in Figure 2 plus imprint length and width. Figure 3. Imprint length extends from the folded foreknee to the
tail. This length defines the bed length of a stall.
Nose-to-tail length describes the measurement from the tail to the nose of a cow standing with her head forward. A cow has a normal crook in her neck when lying and her nose-to-tail length is less than while standing. Imprint length describes the length from folded foreknee to tail while lying in the narrow position. It defines the bed length needed for resting with all body parts on the stall. Imprint length is greater when the cow extends her front legs forward in normal resting positions. When resting in the narrow position, the point of the hock on the
upper hind leg and the extension of the abdomen on the opposite
side define the imprint width. This width is the minimum stall width
for a resting cow. However, for improved comfort, most new tie-stall
barns are being built with stalls wider than the imprint width of
a cow in the narrow resting position. Figure 4. For the rear view of the cow in the photo, imprint width
extends from the left hock to the right abdomen - a distance of
about 52 inches for this cow. It increases when the rear legs extend
outwards or the cow reclines in wide resting positions.
Figure 5. While rising freely on pasture, a cow uses the forward, downward and vertical space outlined by the white lines in the photograph. While rising, this cow lunged forward about 22% of her resting nose-to-tail length.
The space needed for lying and rising motions (lunging) extends forward, downward and upward forehead lunge and bob, vertically and forward for standing and laterally for hindquarter movements. Knowledge of this space is essential for properly sizing the opening at the front of tie stalls, positioning tie rails, choosing the shape and dimensions of stall dividers and avoiding hazards when turning out of stalls. Stall Dimensions as Ratios of Body DimensionAlthough nose-to-tail length is essential, it is a difficult dimension to gather. Since hook-bone width and rump height are easy to measure and since many body dimensions are proportional, these two cow dimensions are useful references for sizing stalls. Table 2 shows stall dimensions, estimated relationships to body dimensions and example calculations for mature Holsteins in a study herd. Figure 13, at the end of this document, is a drawing showing a single, tie-rail stall and several example dimensions for large, medium and small Holsteins. Measure your cows before choosing stall sizes. The standing surface for the feet is the reference for vertical
placement of the tie rail and the bottom of the manger. The tie
rail forward location is a horizontal measurement from the gutter
curb.
* Producers are building most new tie stalls wider than this minimum width. The most common minimum width is 54 inches. Tie Rail or Head RailA tie rail (sometimes called a head rail) is the pipe used as the attachment for the tie chain. It controls the forward location of a cow while standing in the stall and often acts as the water line. Proper location of the tie rail lets a cow stand straight (parallel to the dividers) with all four feet in the stall and rise or lie without contacting it. The vertical location above the bed is about 0.8 x rump height. It mounts forward of the manger curb and over the manger. Standing in the gutter, diagonal standing or neck injuries are the most obvious signs of incorrect placement of the tie rail or obstructions at the front of the stall. Canarm-BSM Agri (Arthur, ON), Donald Horst & Sons (Elmira, ON), Norwell Dairy Systems, (Drayton, ON) and MSD Stabling (Williamsford, ON) manufacture and sell stabling that allows adjustment of the height and forward location of the tie rail. The tie chain with snap should extend only to the height of the manger curb. Figure 6. A tie rail placed 48 inches above the mattress and 86 inches forward of the gutter curb allows medium size cows (about 58-inch rump height) to stand straight in the stall. While standing idly chewing their cuds, their poll will be at tie-rail height and behind it and most of their head will extend below and forward of the tie rail. Larger cows will stand diagonally in stalls with those measurements.
In tie stalls, cleanliness is always a challenge because cows step forward while eating and defecate during the time they are standing forward. Although it has some drawbacks, a front on the manger would keep feed closer to cows and may reduce the reaching-for-feed and stepping-forward seen with sweep-in mangers. An alternative with high tie-rail stalls is to locate the tie rail closer to the manger curb to reduce the frequency of cows stepping forward while eating. Because of the height, there is less need for the rail to be further forward of the manger curb as there is with low tie rails. Wide Opening - Forward or Diagonal LungeWhen rising or lying normally, a mature Holstein uses about 10 feet of space measured from her tail to her most forward lunge distance. The forward space must be unobstructed for frontward lunging and bobbing of the head. Short beds or stalls with obstructions in the lunging space lead to diagonal (corner-to-corner) standing, lying and rising. Cows still lunge forward relative to their body direction, but diagonal or sidewise to the stall. Since the top pipe of the divider becomes a restraint when cows lunge through it, it must have a wide opening to permit easy rising or lying, but be low enough to restrict passage through it. From mattress top to the bottom of this pipe is usually 46 inches in many new stalls. The divider also must have a low mount at manger curb height that does not inhibit the ability to lunge over it. The measurement from the top of the mattress to the top of the bottom pipe should be less than 12 inches. Figure 7. In most barns, the divider provides support for milk
lines and separation of cows in adjacent stalls. This divider leaves
about 30 inches of space for cows to back into an adjacent stall
when exiting. The top pipe drops down at the back so a cow can easily
swing her head over it. This style is suitable for herds feeding
total mixed rations.
Manger CurbA manger curb restricts the forward location of a cow lying in the stall, controls the movement of bedding into feed and retains feed in the manger. It defines the forward limit of the bed length measured from the gutter curb. Concrete and wood have been the most common materials used for
manger curbs. Because of their height, manger curbs interfere with
the normal stride taken during rising. However, some cows stride
into the manger and a slippery surface poses a hazard. Figure 8. A cow-friendly manger curb has beveled corners. The curb acts as an obstruction to forward extension of the legs. To get room for this normal behaviour, cows lie diagonally in their stalls with their front legs stretched into the neighboring bed.
It is common to build a 10-inch curb height measured from the concrete platform to the top of the curb. This measurement decreases to 8 or less inches on the cow side with the addition of a rubber-filled mattress or ample bedding. Despite the 8-inch height, many cows will extend their legs forward into the manger. Therefore, the curb should have rounded, beveled or smoothed edges. Recently, a plastic brisket locator used in free stalls has been modified for use as a manger curb. A flat manger surface and a wooden curb save construction costs. With this technique, producers attach the board (e.g., 2 x 4 or 2 x 6) to the support posts for the stall dividers. Manger HeightThe manger surface is 4 inches higher than the level of the cow's feet. Although this height compromises a cow's ability to bob her head when lying or rising, it is chosen to maximize foot health of the front feet. In barns with the manger at or below bed height, the odds are greater that cows will have sole ulcers on the inner claws of the front feet. The increased risk is related to changes to weight bearing of the inner claws when a cow spreads her front feet apart (laterally) to lower her body while reaching for feed. The 4-inch manger height minimizes the foot-spreading behaviour and the foot problems. The elevated manger also reduces the frequency of cows kneeling to reach feed.
