“…According to Wilson et al (1999), there was no consistent difference in the behaviour of the Holstein calves from week 4 to 18 whether they were kept in open stalls or in individual pens. The results of the present study are consistent with the previous findings (Wilson et al 1999;Kim et al 2015) for feeding, standing, and walking behaviour in heifers and feeding behaviour in steers. However, more walking and less time spent lying down behaviour was observed in steers of G4 and G2, respectively.…”

Effects of group size on performance and behavioural characteristics in Hanwoo calves including heifers (BW = 140.7 ± 3.8 kg, 8 ± 0.5 month) and steers (BW = 167.2 ± 3.4 kg, 8 ± 0.6 month) were evaluated. Fifty-four calves (27 steers and 27 heifers) were assigned to three group sizes, with either 4 (G4), 3 (G3) or 2 (G2) animals per pen, with 3 pen replicates. Data obtained were analysed using the MIXED procedure of SAS. BW was measured bimonthly until the end of the study, and behavioural observations were performed weekly. In heifers, BW showed no differences (P > .05) at neither 8 nor 10 months, however, it was higher (P < .05) in the G4 than the G2 in both 12 and 14 months of age, respectively. In steers, there were no significant differences (P > .05) among the groups in BW, average daily gain, and feed conversion ratio at 8 and 10 months. In heifers, drinking, self-grooming, pairwise grooming were higher in the G4 and G3 than the G2 group (P < .05). The effect of time on performance and behavioural characteristics was highly significant (P < .01). Collectively, the number of 4 calves per pen (32 m 2) can be suggested to improve growth performance in Hanwoo calves.

“…In normal conditions, an additional energy is thus produced to overcome a stressful, perilous situation (Sjaastad et al, 2010). A cortisol concentration is influenced by numerous environmental factors, including stocking density (Kim et al, 2015), also genetic factors, as well as previous experiences; therefore, strict comparisons between various studies are not recommendable. In cattle, the cortisol levels are highly variable, ranging from 0.5 to 9 ng/mL during a routine handling (Grandin, 1997).…”

The aim of the study was to assess the effect of environmental enrichment and different stocking densities on the level of stress in the fattening cattle by measuring salivary cortisol concentration. A total of 320 saliva samples obtained from heifers during the final four-month fattening period was analyzed by a colorimetric competitive enzyme immunoassay. The heifers were housed at 3.3 and 4.5 m2/animal in standard production conditions that were additionally enriched with a mechanical grooming brush and salt blocks in experimental groups. The study results have demonstrated that a cortisol concentration at the end of fattening was significantly higher, as compared with the initial levels in all heifer groups, without significant intergroup differences. There was no significant correlation between the usage of a grooming brush and cortisol concentration, whereas a significant negative correlation was detected between the salt block usage and cortisol concentration, suggesting a beneficial effect of this simple, commercially available and relatively inexpensive environmental enrichment.

“…Recently, it is reported that barn facilities have adopted natural air circulation by elevating roof height, or installed automatic feeders, or hen and cow brushes to better manage livestock [ 7 , 8 ]. However, studies on behavior relevant to rearing space have not focused on proper animal stocking density in Hanwoo [ 9 ].…”

ObjectiveThis study was conducted to analyze the effects of stocking density on growth and carcass quality, and behavior of Hanwoo cattle to conform with global trends, targeting animal welfare production through the practice of environmentally friendly condition.MethodsThirty six steers were randomly assigned to three treatment groups (C: 5 heads, T1: 4 heads, T2: 3 heads) and reared in separate pens with a constant stocking density of 50 m2 (C: 10 m2/head, T1: 12.5 m2/head, T2: 16.67 m2/head) per group from 12 to 30 month of age. Growth performance, behavior and carcass quality traits of each steer were recorded and compared between the treatment groups.ResultsIn general, the average daily gain during the fattening period was lower in group T2 than in T1 and the control groups. However, carcass weight and dressing percentage was lower in the control group than in T1 or T2 groups (p<0.05). Also, marbling score at 30 months of age was the lowest in the control group (p<0.05), while the three heads group (T2) had the greatest longissimus muscle area and marbling score (p<0.05). The behavior of walking time was the greatest in T2 group, while self-grooming and fighting occurred with the most frequency in the control group (p<0.05).ConclusionOur results show that the steers in more spacious stocking density had better carcass quality and wellbeing related behaviors, indicating that a lower density has a positive effect on raising management and carcass quality. Thus it is a need to install appropriate pens fitted to welfare-oriented management practices from growing to fattening period in Hanwoo cattle.
