End of Project ReportStudy 1. Animal welfare index (AWI): an on-farm survey of beef suckler farms in Ireland
Summary
The objectives were to (i) examine the welfare status of Irish beef suckler herds using an animal
welfare index (AWI) adapted from a previously validated welfare assessment method (TGI); (ii)
determine the influence of the stockpersons’ status (full: FT or part-time: PT), their interest in farming
and herd size on the AWI; and (iii) compare the AWI with the TGI. Beef suckler farms (196
throughout 13 counties) were assessed once with housed cattle and once with cattle at grass using
the AWI. Twenty-three of the 196 farms were revisited a year after using the AWI and the TGI.
Thirty-three indicators were collected in five categories: locomotion (5 indicators); social interactions
(7), flooring (5), environment (7) and stockpersonship (9). Three indicators relating to the size of the
farm were also collected. The mean AWI was 65% and ranged from 54% to 83%. The grass period
represented 16.5% of mean total points of the AWI. Seventy percent of the farms were rated as
“Very Good” or “Excellent”. There was no difference (P > 0.05) in AWI between FT and PT farmers.
PT farmers had greater (P = 0.01) “social interactions”: calving (P = 0.03) and weaning (P < 0.001)
scores. FT farmers had cleaner animals (P = 0.03) and less lameness (P = 0.01). The number of
animals and the interest of the stockperson were negatively and positively correlated (P = 0.001),
respectively, with the AWI. A hierarchical classification was performed to examine how the indicators
influenced the AWI. Farms could be categorized into three classes, the most discriminating factors
for the classes were the interest of the farmer (higher scores when the farmer was more interested in
farming) and the number of animals (higher scores when the herds were smaller).
Study 2. Investigation and specificity of behavioural fear responses of heifers to
different fear-eliciting situations involving humans.
Summary
This study investigated the specificity of fear responses in housed beef heifers’ over time using four
behavioural tests; flight, docility, fear and chute tests. The flight, (time to join peers and avoidance
distance), docility (isolation and handling) and fear (4 phases; responses of isolated heifers in (i), the
absence (ii), the presence, of food and responses to a stationary human (iii) without and (iv) with
visual contact of their peers) tests were carried out over three consecutive days, in that order,
commencing on day 30 and again on day 80 post-housing. The chute test (movement through a race
and agitation of heifers during blood sampling) was performed on day 84 post-housing. Scores
(higher scores meant less fearful animals) were assigned to the fear responses. Heifers had the
lowest (P < 0.05) scores during phases (i) and (iii) of the fear test and the highest (P< 0.05) during
phase (iv). The most docile heifers during the docility test were the most agitated during the chute
test (P < 0.001). The fear scores were sTable over time for the docility test but decreased for the fear
test. The fear scores when restrained (chute test) were not correlated with other scores except for
the agitation. A PCA showed that two components (avoidance of stimulus and general agitation
explained 49% of the total variation. In conclusion, this study showed that fear responses of heifers
can vary over time and that fear is not unitary but multidimensional. Consequently, fear responses
are condition specific and tests assessing fear should consider their specificity.European Union Structural Funds
