“…In this study the CC hens tended to be more fearful than hens in furnished cages. Tanaka et al (1993) reported that increasing environmental enrichment can reduce the fear in hens. Our results agreed with this observation.…”

This study was conducted to compare the effects of layout of furniture (a perch, nest, and sandbox) in cages on behavior and welfare of hens. Two hundred and sixteen Hyline Brown laying hens were divided into five groups (treatments) with four replicates per group: small furnished cages (SFC), medium furnished cages type I (MFC-I), medium furnished cages type II (MFC-II), and medium furnished cages type III (MFC-III) and conventional cages (CC). The experiment started at 18 week of age and finished at 52 week of age. Hens’ behaviors were filmed during the following periods: 8:00 to 10:00; 13:00 to 14:00; 16:00 to 17:00 on three separate days and two hens from each cage were measured for welfare parameters at 50 wk of age. The results showed that feeding and laying of all hens showed no effect by cage type (p>0.05), and the hens in the furnished cages had significantly lower standing and higher walking than CC hens (p<0.05). The birds in MFC-III had significant higher preening, scratching and feather-pecking behavior than in the other cages (p<0.05). No difference in nesting behavior was found in the hens between the furnished cages (p>0.05). The hens in MFC-I, −II, and −III showed a significant higher socializing behavior than SFC and CC (p<0.05). The lowest perching was for the hens in SFC and the highest perching found for the hens in MFC-III. Overall, the hens in CC showed poorer welfare conditions than the furnished cages, in which the feather condition score, gait score and tonic immobility duration of the hens in CC was significantly higher than SFC, MFC-I, MFC-II, and MFC-III (p<0.05). In conclusion, the furnished cage design affected both behavior and welfare states of hens. Overall, MFC-III cage design was better than SFC, MFC-I, and MFC-II cage designs.

Effects of Perches on Behavior, Heart Rate, Body Temperature and Locomotor Activity of Caged Hens

2004

This study was carried out to investigate the behavior and physiological conditions of hens housed in cages with or without perches. The physiological parameters investigated were heart rate (HR), body temperature (BT) and locomotor activity (LA) using a radiotelemetry system. Six White Leghorn hens (3*-weeks-old) were used after transmitters implantation. Following the preconditioning period for at least +* days, the behavioral and physiological data were recorded for , consecutive days, which were the data in the control cages without perches (C). After that, the same hens were exposed to the following types of cages : conventional cages with perches available all day (P,.), followed by conventional cages with perches from +3.** to *2.** hours (P+-), and finally housed in conventional cages with perches from +3.** to *..** hours (P3). The interval between each trial was a +* days to habituate the hens with their new environment. Immediately following this, the behavioral and physiological data were recorded for , consecutive days for each trial. The only significant behavioral di#erence was found in the time consumed in resting, which increased significantly in P,. cages than in C and P 3 cages (P῍*.*/). Our physiological data during the light period indicate that the hens in P,., P+-and P3 cages had a significantly higher heart rate than in C cages (P῍*.*+). On the other hand, hens in P,. cages had a significantly lower BT than in C, P+-, and P3 cages (P῍*.*+), however, hens in P,. cages had a significantly higher LA than in C, P+-and P3 cages (P῍*.*+). Moreover, during the dark period, hens in P,. cages had a significantly lower HR, BT and LA than all the other treatment (P῍*.*+). These results suggest that the use of cages with perches might be important for the hens' welfare than those without perches.

Integration of Grape-Duck Production Pattern Boosts Duck Behavior, Meat Quality, Fecal Microbiota and Soil Microorganisms

et al. 2023

The combination of planting and breeding, an agricultural production system, makes full use of land, ecological space and time, increasing the utilization rate and yield of both plant and animal production. This experiment aimed to explore the effects of the grape-duck farming system by analyzing behavior, meat quality, and fecal microbiota of ducks and the soil microbiota. The results differed significantly on the expressions of positive behaviors between the breeding group and the combination of planting and breeding group, including actions of foraging, feeding and walking (p < 0.05), while the free-range group showed more stereotyped behavior of no apparent purpose or significance. In terms of meat quality, the yellow value b* of the combination group was significantly higher than that of the free-range group (p < 0.05). The drip loss rate of the planting and breeding group was 1.80%, and the drip loss rate of the combination group was 3.80%, with a significant difference (p < 0.05). The combination of planting and rearing increased the alpha diversity of soil microbiota (p < 0.05), but it had no obvious effect on the fecal microbiota of ducks. PCoA showed that soil microorganisms and fecal microbiota are obviously separated and clustered. In conclusion, the combination production mode of “grape-duck” had a positive effect on duck behavior, meat quality, and soil microorganisms, however, it changed virtually nothing in duck production performance and fecal microbiota.
