On-Farm Welfare Assessment Protocol for Adult Dairy Goats in Intensive Production Systems

Simple Summary The Animal Welfare Indicators (AWIN) project developed a practical welfare assessment protocol for lactating dairy goats in intensive husbandry systems, using animal-based indicators that cover the whole multidimensional concept of animal welfare. The strict collaboration between scientists and stakeholders resulted in an easy-to-use protocol that provides farmers or veterinarians with comprehensive but clear feedback on the welfare status of the herd in less than three hours. The protocol, which highlights key points and motivates farmers to achieve improvements, has received much attention from interested parties. Abstract Within the European AWIN project, a protocol for assessing dairy goats’ welfare on the farm was developed. Starting from a literature review, a prototype including animal-based indicators covering four welfare principles and 12 welfare criteria was set up. The prototype was tested in 60 farms for validity, reliability, and feasibility. After testing the prototype, a two-level assessment protocol was proposed in order to increase acceptability among stakeholders. The first level offers a more general overview of the welfare status, based on group assessment of a few indicators (e.g., hair coat condition, latency to the first contact test, severe lameness, Qualitative Behavior Assessment), with no or minimal handling of goats and short assessment time required. The second level starts if welfare problems are encountered in the first level and adds a comprehensive and detailed individual evaluation (e.g., Body Condition Score, udder asymmetry, overgrown claws), supported by an effective sampling strategy. The assessment can be carried out using the AWIN Goat app. The app results in a clear visual output, which provides positive feedback on welfare conditions in comparison with a benchmark of a reference population. The protocol may be a valuable tool for both veterinarians and technicians and a self-assessment instrument for farmers.

Results of testing the prototype of the AWIN welfare assessment protocol for dairy goats in 30 intensive farms in Northern Italy

Abstract The AWIN project aimed at developing an on-farm welfare assessment protocol for adult dairy goats. A prototype protocol was tested in 30 intensive dairy goat farms to evaluate its feasibility in farms of different size. Time for applying the prototype was recorded and any other constraint was taken into account. Moreover, data collected during the prototype testing provided information on the prevalence of welfare issues in intensive dairy goat farms in Northern Italy. The prototype included 25 animal-based indicators (14 group- and 11 individual-level indicators). The prototype showed a good on-farm feasibility and it was highly accepted among stakeholders, as its application did not interfere with the daily routine. Approximately 2 h were required for the application of the prototype. When feeding racks were available, using them for locking the animals during the individual assessment resulted advantageous to speed the data collection and to reduce handling stress to the goats and disturbance to the farmers. Farm size and different management systems influenced the prevalence of some indicators, with small farms in general better welfare conditions compared to larger farms. The results of the present study represent an important starting point to set up an epidemiological database that may lead to improve the welfare status of goats.

On-farm welfare assessment of dairy goat farms using animal-based indicators: the example of 30 commercial farms in Portugal

ABSTRACT Welfare assessment can play multiple roles in the path to welfare improvement. In the dairy goat area, identification of the main welfare problems across countries and different production systems is needed. By the application of a prototype welfare assessment protocol, based on animal-based indicators, we aimed to provide an insight into the main welfare problems affecting intensively kept dairy goats in Portugal. Thirty farms, organised in three size categories, were assessed. The main areas of concern were claw overgrowth, queuing at feeding and hindquarter dirtiness, with larger farms heading higher concerns. Additionally, this paper aimed to investigate indicators’ consistency over time. Ten of the 30 farms were revisited four months later, during which no major husbandry changes were made. Our results showed an overall consistency. This study can help define intervention thresholds or minimum legal levels for each indicator, by determining their overall prevalence.

An innovative tool for on-farm data collection and information sharing

The CoreOrganic2 research project ProPIG is carried out in 75 organic pig farms in 8 European countries (AT; CH; CZ; DE; DK; FR; IT; UK) to improve animal health, welfare and nutrition using farm customised strategies. For future on-farm application (e.g. advisory/certification activities, which are mostly carried out during one day visits), a practical, automatic recording and feedback tool was developed. This should allow on-farm data collection, import of data into a database and the possibility for benchmarking, including a printed output for the farmer to facilitate immediate discussion of results and improvement strategies. To document not only animal health and welfare, but also integrate diet composition and productivity data, it was important to choose key indicators from all areas, which would be available across all eight countries. Based on existing on-farm welfare assessment protocols (e.g. WelfareQuality®, CorePIG) indicators were selected by the consortium, which were then transferred into a Software programme (“PigSurfer”). This Software is available as Desktop- or Android version to be used on Tablet PCs, so that on-farm data (interview with farmer; direct observations on weaners, finishers, sows; productivity and treatment records; feed) can be entered directly. During two visits a database was built and a “Farm report” was printed for each farm, with benchmarking of results, feedback and discussion with the farmer. After a year, “PigSurfer” was used to carry out the following complete process during one day visits across Europe: Surveillance of health and welfare, feedback of data in comparison with results from the previous year as well as benchmarking with 75 other pig farms and printing a report. “PigSurfer” is a promising tool for communicating health and welfare, as it provides not only a database, which can be continuously extended, but is an important step to move from research to on-farm application across Europe.

Consistency over time of animal-based welfare indicators as a further step for developing a welfare assessment monitoring scheme: The case of the Animal Welfare Indicators protocol for dairy goats

Consistency over time (COT) of animal-based indicators is key to a reliable and feasible welfare protocol, indicating that results are representative over long-term situations. High levels of consistency ensure fairness for the farmer and credibility of the system. In addition, indicator COT reduces recording costs, as having indicators that do not change over a long period of time will require less farm visits to achieve reliable estimates. To date, COT of animal-based indicators included in the welfare assessment of dairy goats has never been tested. Therefore, our aim was to investigate COT of animal-based indicators included in the Animal Welfare Indicators (AWIN) welfare assessment prototype protocol for dairy goats. To meet this goal, a study was designed where an average of 3 mo elapsed between 2 sets of visits to the same 20 dairy goat farms (10 in Portugal and 10 in Italy), with no major changes in management routines or housing conditions occurring during this period. Initially, we performed a Wilcoxon signed rank test to investigate whether the results obtained during the 2 visits were significantly different. After this preliminary screening, the indicators presenting nonsignificant differences between visits were submitted to a second step analysis, where discriminative and evaluative analyses were conducted to reach a final indicator lineup. The discriminative approach helped distinguishing among farms, whereas the agreement analysis showed us the range of differences between repeated assessments. Some particular conclusions could be drawn from this combined analysis, helping to the development of the final AWIN welfare assessment protocol for dairy goats and as a further step to develop a welfare assessment monitoring scheme for this and other species. In this sense, the AWIN welfare assessment protocol allows for the quick differentiation between farms based on the identification of persistent welfare problems, by recording highly consistent and feasible indicators. In a second step, a more comprehensive protocol, consisting of indicators more likely to be subject to variations along time, was applied. Repeated assessments and long-term studies of indicator consistency are needed to help determine the frequency of visits required to obtain a consistent and feasible welfare assessment scheme. This paper adds to the literature by providing guidance on the variability of animal-based indicators over time.

Multi-dimensional assessment and scoring system for dairy farms

Abstract The aim of the study is to develop a scoring system for dairy farms in order to give specific information about the product and production process of milk. The scoring system, based on a multi-dimensional approach, was developed on the basis of data collected in 29 Italian dairy farms and included different aspects. For the evaluation of animal welfare, a selection of indicators set up in the European Project® assessment protocol for cattle 2009 was used. Environmental sustainability of milk production was assessed by a cradle-to-farm-gate Life Cycle Assessment. Laboratory analyses were carried out on bulk tank milk to evaluate microbiological, nutritional and nutraceutical quality. Nineteen variables were selected and retained to define six quality aspects: animal welfare, environmental and economic sustainability of farms, microbiological, nutritional and nutraceutical quality of milk. Each farm was visited twice; each visit received, for each variable, a score between 1 and 3 based on the frequency distribution of that variable in the farm sample. The relation among farm characteristics and quality aspects showed the importance to maximise dairy efficiency to improve environmental and economic sustainability of the farms and the inclusion of hay in dairy cows’ ration to enhance the nutraceutical and nutritional quality of milk. The proposed multi-dimensional scoring system is a practical tool: for the farmer, to support decisions for improving the quality of the product and the productive process; for the dairy company, as a value-added opportunity; for the consumer, who receives detailed information about nutritional characteristics and production system of dairy products.

Qualitative behavioural assessment of intensive and extensive goat farms

Chronic stress is a long-lasting negative emotional state which induces negative consequences on animals’ behavior. This study aimed at assessing whether unpredictable and repeated negative stimuli (URNS) influence feeding behavior in quail, and whether this can be modulated by their emotionality. Two lines of quail divergently selected on their inherent emotionality (low emotionality, STI; high emotionality, LTI) were either daily exposed to URNS or undisturbed from 17 to 40 days of age (n=32 for each line, in each group). During this time, quail were submitted twice to a sequential feeding procedure: they were offered a hypocaloric diet (7% less caloric than the normocaloric diet) on odd days and a hypercaloric diet (7% more caloric) on even days, for 8 days; then, they received a normocaloric diet (metabolizable energy=12.56 MJ) for 3 days. This sequential feeding procedure was used to assess anhedonia and diet preferences thanks to choice tests (hypo vs. hypercaloric diets) performed at the end of each period. Short-term (30 min) and daily intake were also measured each day. Behavioral tests were performed to assess quail’s emotional reactivity. Results showed that URNS enhanced quails’ emotional reactivity, e.g. in the reactivity to human test, disturbed quail came later (P=0.011) and spent less time (P 0.1), but URNS reduced their daily intake during the 2nd period (P<0.05). Motivation for each diet (assessed by their short-term intake) was differently affected by URNS during the 2nd period: STI quail decreased their motivation to eat the hypercaloric diet (P<0.01) whereas LTI increased their motivation to eat the hypocaloric diet (P<0.01). In conclusion, both lines of quail experienced a chronic stress as URNS induced an increase of their emotional reactivity. Interestingly, URNS induced opposite changes in quail’s feeding behavior: LTI disturbed quail seemed to express a short-term compensatory behavior because of their high motivation to eat, whereas STI disturbed quail seemed to be in a devaluation process as shown by their anhedonia and their decrease of daily intake.Farm animals have to adapt to human presence from birth and being handled may lead to fear and stress reactions. It is known that the mother can be used as a postnatal model in the development of young-human relationship. Through her, some information like auditory ones may even be learnt prenatally. We tested this idea in pigs because they communicate a lot by acoustic signals. The hypotheses were that prenatal experience with human voice could modify behavioural reactions to the experienced voice and to an unfamiliar voice expressing different emotions. We worked with 30 pregnant sows from the last month of gestation. Ten sows (treatment A) were submitted to recordings of human voices during handling: vA during positive interactions and vB during negative interactions, twice a day, 5 days a week, for 10 minutes. Ten other sows (treatment B) received the contrary, i.e. vB during positive interactions and vA during negative interactions. Ten last sows (treatment C) received no vocal stimulations during handling sessions. Two days old piglets (36 A, 39 B, 35 C) were submitted to a 5 min choice test between voices vA and vB in a testing pen (2×1 m). Each voice was played back through loudspeakers positioned at each end of the pen. At 15-18 days of age, 20 other piglets from each treatment were tested in the same conditions except that we played back the voice of an unknown person, reading the same text with a joyful or angry intention. In both tests we recorded vocalisations and locomotion. Data were analysed using non parametric statistics (Statview). In both tests, A and B piglets started to move sooner (P 0.05) to be and the time spent (178 s (46s)) close to the loudspeakers did not depend on the treatment (P>0.05). We also found no difference between the time spent close to one loudspeaker or the other, neither for vA versus vB, nor for joyful versus angry intention (P>0.05). The results show that the prenatal experience of human voice reduces postnatal behavioural reactions of stress (vocalisations, latency to move) during the playback human voices. However, it does not seem to induce specific attraction toward human voice, or human emotional intention. Therefore prenatal experience with human voice may be a good way of reducing fear reactions to human voice after birth.
