Three groups of 15 crossbred castrated ♂ pigs were kept from 40 to 200 lb live weight in a house with temp. controlled at 65°-70° F, and 3 similar groups in a half-open house. A 7th group of 15 was kept in a yard with a portable shelter. In the 2 houses groups of pigs were allowed 10, 8 or 6 ft²...

Varied types of cow cubicles were constructed on top of an existing slatted floor to enable observations to be made on length of cubicle (optimum for Shorthorns and Friesians was 6 ft. 9 in.); width of cubicle (optimum 3 ft. 6 in. to 3 ft. 9 in.); type of floor (an unbedded gently sloping concrete...

On 2 farms, Thornber's 606 and 404 hybrids were housed in battery cages of 4' x 15" floor area at densities of 8-14 birds per cage. Some of the cages were subdivided, and the number of birds per sub-unit varied from 2 to 6. The 404 is a medium-sized, docile bird, and the 606 a White Leghorn hybrid...

At approx. 6 mths. of age, 2 groups of Australorps were housed resp. on deep litter floors or in individual cages. Birds were scored for aggressiveness in paired encounters with 6 panels of birds. There were no significant regressions of egg weight or egg number on aggressiveness score for caged...

This is a circular cowshed in which the animals stand in individual stalls on a revolvable platform which rotates around a forage feed silo. The cows are milked, fed, cleaned, bedded and subjected to any other necessary operation as they are delivered to and held for a suitable length of time at...

In the 2 types of housing resp., the interval from calving to 1st heat averaged 51.95 and 62.54 days for 225 and 162 cows, and service period 120.45 and 120.27 days. There was a significant correlation between the 2 traits (0.33) in traditional stalls only. Data are tabulated separately for the...

The bacteriological quality of milk was studied for cows (/') housed in traditional conditions with individual stalls, (ii') in loose-housing and (iii) in loose-housing with cubicles. Average total micro-bial, colimetric, proteolytic and thermoduric counts were comparable for (i) and (ii) but the...

Large White and Berkshire pigs were observed from 8 to 16 weeks of age in pens of 6 to 10 pigs. Large Whites were more aggressive than Berkshires. Social rank was positively correlated with initial weight. Initial weight and social rank both influenced growth; the relative effect of rank compared...

The pros and cons of stall barns and loose housing are discussed. Stall barns are still popular in the northern states, probably because they are warmer to work in. A survey in Wisconsin showed that 85% of new buildings built in 1955 and 91% of the barns remodelled in that year were stall barns....

In July and November 3 cows were tethered in stalls and 3, not tethered, had access to a yard. Activity during 24 h was recorded. Tethered cows spent longer eating and ate more frequently. Longer was spent ruminating after hay and silage in November than after green fodder in July. Most ruminating...
