Cage size preference in rats in the Laboratory
- Journal of Applied Animal Welfare Science
, 2002
"... The size of an enclosure is an integral part of how well it accommodates a nonhuman animal’s welfare; however, most enrichment studies concentrate on modifying the area inside the enclosure rather than enlarging it. It has been suggested that rats have little need for more cage space, but there is n ..."

; binomial z, p <.05). When the rats shared the chosen cage with 4 famil-iar cage mates, their preference for the larger cage did not become any stronger (paired t(9) = –.820, p>.05). The results suggest that rats should be given a somewhat larger space allowance but could share it with up to 4 other
Effects of Cage Type and Mating Ratio on Fertility in Japanese
"... mating ratio cage type Japanese quail In this study, the effects of mating ratio and cage type on the percentage of fertility in Japanese quail were investigated. For this aim, 124 breeder quails were housed in individual cages and 164 breeder quails were housed in colony cages. In total, 1646 eggs ..."

PERFORMANCE OF MATED VERSUS NON-MATED COTURNIX
, 1969
"... During a study of the genetic control of lysine utilization in the avian species Co-tumix cotumix japonica (Godfrey, 1968), it was routine to select breeders on the basis of percentage growth rate (Brody, 1945) from two to four weeks of age when fed either a ration deficient in lysine con-tent, or a ..."

while fed the adequate diet. Breeders were selected on an individual and family basis, and selected females were pair mated with selected males from unrelated familes. The full female sibs that were not used as breeders were re-tained and held in individual cages, so that a comparison of the performance

Control of mating preferences in mice by genes in the major histocompatibility complex
- J Exp Med
, 1976
"... While observing AKR and AKR backcross mice being bred to produce an AKR-H-2 b congenic mouse strain, one of us (J. B.) noticed that homozygous H-2 b c ~ d were more attracted to heterozygous H-2 O:H-2 k? Q than to H-2 b homozygous Q Q. Meanwhile another of us (L. T.), unaware of these observations, ..."

Fragrances, male display and mating behaviour of Euglossa hemichlora: a flight cage experiment
"... Abstract. Male euglossine bees (Apidae: Euglossini) collect volatile substances (fragrances) from floral and nonfloral sources and store them in hair-filled cavities in their hind tibiae. Over time, males accumulate large quantities of complex and species-specific blends of fragrances. Various hypot ..."

and difficult to observe in nature. Here, we report a flight cage experiment performed in Panama that permitted mating between virgin females (raised from brood cells) and males captured in the forest at fragrance baits. In the cage, eight individually marked males defended small territories around vertical
MATING PERFORMANCE AND SPATIAL DISTRIBUTION OF MEDFLY (DIPTERA: TEPHRITIDAE) WHITE PUPA GENETIC SEXING MALES UNDER FIELD CAGE CONDITIONS
"... A BSTRACT In mixed populations of wild and males from T (Y;5) 1-61 white female pupa genetic sexing strain of Ceratitis capitata (Wiedemann), sterilized males of the genetic sexing strain expressed calling, lekking and mating compatibility with their wild counterparts. Nevertheless, their mating pe ..."

Mating Conditions Favorable for Improving Mating Rate of the Bumblebee, Bombus ignitus
, 2007
"... We investigated mating conditions of photoperiod, illumination and temperature during mating periods, care temperature of queen before mating, mating period and number of queen per mating cage to improve mating rate of Bombus ignitus. Among pho-toperiodic regimes of 12L, 14L and 16L during mating pe ..."

EXPERIMENTAL EPIDEMIOLOGY OF TUBERCULOSIS THE EFFECT OF ELIMINATING EXPOSURE TO ENTERIC INFECTION ON THE INCIDENCE AND COURSE OF TUBERCULOSIS ACQUIRED BY NORMAL GUINEA PIGS CONFINED WITH TUBERCULOUS CAGE MATES
, 1930
"... It was found by Perla (1) and confirmed in a previous paper (2) that guinea pigs exposed to tuberculous cage mates acquire a disease that is largely enteric in origin, the main source of contagion being the faecal matter of the inoculated animals. It was thought desirable to determine what effect if ..."
