“…Ready access to fresh water is important to maintain full health and vigor; welfare can be compromised if animals cannot drink whenever they feel the need to, either because fresh water is not available or because of competition with other goats. Continuous and prolonged lack of access to fresh water may eventually lead to chronic dehydration, especially during hot periods (Ogebe et al, 1996;Darcan et al, 2007).…”

“…This behavior is generally socially facilitated (Forkman, 1996) and quite synchronized (Rook and Penning, 1991). Reduced possibility of simultaneous drinking can lead to decreased drinking time and hence lower water intake (Ogebe et al, 1996;Van et al, 2007). Queuing animals and displacements at the drinkers may be used to detect animals suffering from thirst.…”

“…Some physiological and blood parameters have been identified as valid indicators. Water intake, rumination rate, rectal temperature, pulse and respiration rate (Ogebe et al, 1996;Darcan et al, 2007), skin temperature (Darcan et al, 2007), glucose, total cholesterol, urea, and cortisol (Sejian and Srivastava, 2010) increase during heat stress situations. In contrast, total protein and aldosterone decrease under these conditions (Sejian and Srivastava, 2010).…”

This paper reviews animal-based welfare indicators to develop a valid, reliable, and feasible on-farm welfare assessment protocol for dairy goats. The indicators were considered in the light of the 4 accepted principles (good feeding, good housing, good health, appropriate behavior) subdivided into 12 criteria developed by the European Welfare Quality program. We will only examine the practical indicators to be used on-farm, excluding those requiring the use of specific instruments or laboratory analysis and those that are recorded at the slaughterhouse. Body condition score, hair coat condition, and queuing at the feed barrier or at the drinker seem the most promising indicators for the assessment of the "good feeding" principle. As to "good housing," some indicators were considered promising for assessing "comfort around resting" (e.g., resting in contact with a wall) or "thermal comfort" (e.g., panting score for the detection of heat stress and shivering score for the detection of cold stress). Several indicators related to "good health," such as lameness, claw overgrowth, presence of external abscesses, and hair coat condition, were identified. As to the "appropriate behavior" principle, different criteria have been identified: agonistic behavior is largely used as the "expression of social behavior" criterion, but it is often not feasible for on-farm assessment. Latency to first contact and the avoidance distance test can be used as criteria for assessing the quality of the human-animal relationship. Qualitative behavior assessment seems to be a promising indicator for addressing the "positive emotional state" criterion. Promising indicators were identified for most of the considered criteria; however, no valid indicator has been identified for "expression of other behaviors." Interobserver reliability has rarely been assessed and warrants further attention; in contrast, short-term intraobserver reliability is frequently assessed and some studies consider mid- and long-term reliability. The feasibility of most of the reviewed indicators in commercial farms still needs to be carefully evaluated, as several studies were performed under experimental conditions. Our review highlights some aspects of goat welfare that have been widely studied, but some indicators need to be investigated further and drafted before being included in a valid, reliable, and feasible welfare assessment protocol. The indicators selected and examined may be an invaluable starting point for the development of an on-farm welfare assessment protocol for dairy goats.

“…Uribe-Velásquez et al 2001relataram que cabras alpinas, tanto em condições de termoneutralidade como sob influência de estresse em câmara bioclimatológica, apresentaram médias de temperatura retal, no turno da tarde, superiores às do período da manhã sendo que, nos animais sob estresse, os valores da temperatura retal foram superiores, devido a uma hipertermia temporária nesses animais. Para Ogebe et al (1996) valores de temperatura retal e freqüência respiratória são influenciadas pelo sexo e pela estação do ano.…”

Objetivou-se, com este trabalho, verificar o efeito da época do ano e período do dia sobre os parâmetros fisiológicos de reprodutores caprinos mestiços de Anglo-Nubiana com caprinos sem padrão racial definido, no Semi-árido paraibano. Utilizaram-se 20 caprinos machos, distribuídos em um delineamento inteiramente casualizado no esquema fatorial 2 x 2, duas épocas: E1, maio a agosto e E2, setembro a dezembro, e dois turnos, manhã e tarde, repetidos no tempo, totalizando 80 parcelas. Para os parâmetros hematológicos estudou-se apenas o efeito da época do ano. Os parâmetros fisiológicos, temperatura retal e freqüência respiratória, foram influenciados (P < 0,01) pelo turno, enquanto a temperatura superficial sofreu influência (P < 0,01) de ambos os fatores, turno do dia e época do ano. Os parâmetros hematológicos, hemácias, hematócrito e volume globular médio, foram influenciados (P < 0,05) pela época do ano. A pouca variação dos parâmetros fisiológicos de caprinos mestiços de Anglo-Nubiana com sem padrão racial definido, demonstra alto grau de adaptação à temperaturas elevadas. No período de maior temperatura a perda de calor através da forma evaporativa, respiração, determina a elevação do hematócrito e do volume globular médio.

“…Many other animal-based indicators have been proposed for the assessment of thermal stress in goats, such as water intake, rumination rate, rectal temperature (Ogebe et al 1996;Darcan et al 2007), skin temperature (Darcan et al 2007), respiratory rate (Silanikove 2000a), body condition score (McGregor and Butler 2008), as well as blood parameters (e.g. glucose, total cholesterol, urea, cortisol, total protein and aldosterone; Sejian and Srivastava 2010), or time budget of general activities (e.g.…”

Feasibility and validity of animal-based indicators for on-farm welfare assessment of thermal stress in dairy goats

This investigation tested the feasibility and validity of indicators of cold and heat stress in dairy goats for on-farm welfare assessment protocols. The study was performed on two intensive dairy farms in Italy. Two different 3-point scale (0-2) scoring systems were applied to assess cold and heat stress. Cold and heat stress scores were visually assessed from outside the pen in the morning, afternoon and evening in January-February, April-May and July 2013 for a total of nine sessions of observations/farm. Temperature (°C), relative humidity (%) and wind speed (km/h) were recorded and Thermal Heat Index (THI) was calculated. The sessions were allocated to three climatic seasons, depending on THI ranges: cold (<50), neutral (50-65) and hot (>65). Score 2 was rarely assessed; therefore, scores 1 and 2 were aggregated for statistical analysis. The amount of goats suffering from cold stress was significantly higher in the cold season than in neutral (P < 0.01) and hot (P < 0.001) seasons. Signs of heat stress were recorded only in the hot season (P < 0.001). The visual assessment from outside the pen confirms the on-farm feasibility of both indicators: No constraint was found and time required was less than 10 min. Our results show that cold and heat stress scores are valid indicators to detect thermal stress in intensively managed dairy goats. The use of a binary scoring system (presence/absence), merging scores 1 and 2, may be a further refinement to improve the feasibility. This study also allows the prediction of optimal ranges of THI for dairy goat breeds in intensive husbandry systems, setting a comfort zone included into 55 and 70.
