Welfare Assessment on Pasture: A Review on Animal-Based Measures for Ruminants

Outdoor and extensive farming systems allow animals to behave in a natural way and are often perceived as welfare friendly. Nonetheless, the natural environment poses multiple challenges to the welfare of animals, sometimes hampering their capacity to cope. Welfare assessment in outdoor and extensive systems has been rarely investigated, and little is known about the most appropriate indicators. The aim of this review was to identify animal-based measures of welfare to apply in extensive and pasture-based systems in domestic ruminants. Through the use of a dedicated software for systematic reviews, 810 papers were screened and a total of 52 papers were retained for in-depth analysis. ABM resulting from these papers were initially divided according to the species (cattle and small ruminants, including sheep and goats) and then to four principles: comfort, behavior, feeding and health. The results showed that welfare data were collected applying different methodologies, with an increasing use of sensors in recent years. The need to herd and restrain animals for individual data collection is one of the major constraints to data collection in extensive farming systems. It is suggested that welfare assessment in outdoor/extensive farming systems is carried out by following shared procedures in order to provide evidence of the higher animal welfare claims that these products often imply compared to indoor systems

Evaluation of pain mitigation strategies in goat kids after cautery disbudding

ABSTRACT - Simple Summary Disbudding is a routine procedure performed in goat kids at an early age, especially the ones in the dairy industry. The procedure is mainly done to increase safety for other animals and workers in intensive dairy farms. Disbudding is a painful procedure that affects the welfare of the kids. Effective and practical pain mitigation strategies to reduce the suffering of goat kids due to disbudding have not yet been found. We studied two different pain mitigation strategies for this procedure and concluded that they were not entirely effective. Consumers are increasingly aware of animal farming practices, especially the ones that can lead to suffering and pain, such as disbudding. It is crucial that pain mitigation strategies as well as possible alternative solutions to disbudding continue to be investigated. Nowadays, most of the goat milk production in developed countries is done in intensive indoors production systems. In these systems, procedures such as disbudding are performed routinely. Disbudding is done in young goat kids and is a recognised as a painful procedure. Pain mitigation strategies have been extensively researched, but a method that is effective in mitigating pain as well as being safe and practical has not yet been found. In this paper we used three treatment groups: one control and two groups with pain mitigation strategies for cautery disbudding, one using local anaesthesia (lidocaine) and a second one using local anaesthesia (lidocaine) plus an analgesic (flunixin meglumine). The behaviour of twenty-seven goat kids was recorded for three hours after disbudding. Overall, the goat kids that received both pain mitigation treatments dedicated more time performing active and positive behaviours. Nevertheless, the incidence of behaviours related to pain and discomfort was not consistently reduced. Research is still needed to find a practical and effective pain mitigation strategy for disbudding. A solution to this challenge would improve animal welfare as well as address societal concerns linked to the suffering of farm animals.info:eu-repo/semantics/publishedVersio

The Perception of Ecosystem Services of Mountain Farming and of a Local Cheese: An Analysis for the Touristic Valorization of an Inner Alpine Area

Mountain husbandry systems and their related products may directly or indirectly provide either ecosystem services (ESs) or disservices to humanity. The present study aims to evaluate the perception that a local mountain community has towards animal husbandry in the Lanzo Valleys (Piedmont, Italy) and towards the typical local dairy product, Toma di Lanzo, as well as to investigate the consumers\u2019 habits and preferences, to detect possible positive impacts on mountain tourism. A questionnaire was delivered to 233 respondents. The perception of the impact was scored using a five-point Likert scale. The results show a very positive perception of the product Toma di Lanzo because of its origin and type of processing, with different perceptions of the local society depending on age (p < 0.01), residence (p < 0.01), and education level (p < 0.05). The respondents had a very positive awareness of the impact of mountain livestock farming in the Lanzo Valleys. The most important perceived ESs are cultural identity and maintenance of local breeds. Women, non-residents, and respondents with an intermediate education level generally had a more positive perception of ESs. There was a very low perception of disservices derived from mountain animal farming. The main perceived obstacles to the spread of benefits derived from these farming systems were the scarce presence of specific supporting politics and the low income generated by mountain farming activities. The coexistence of touristic activities and extensive livestock farming systems has to be associated with a better promotion of mountain products like Toma di Lanzo to improve the sustainability of mountain regions

Long-term follow-up of patients with Bartter syndrome type I and II

Background. Little information is available on a long-term follow-up in Bartter syndrome type I and II. Methods. Clinical presentation, treatment and long-term follow-up (5.0-21, median 11years) were evaluated in 15 Italian patients with homozygous (n = 7) or compound heterozygous (n = 8) mutations in the SLC12A1 (n = 10) or KCNJ1 (n = 5) genes. Results. Thirteen new mutations were identified. The 15 children were born pre-term with a normal for gestational age body weight. Medical treatment at the last follow-up control included supplementation with potassium in 13, non-steroidal anti-inflammatory agents in 12 and gastroprotective drugs in five patients. At last follow-up, body weight and height were within normal ranges in the patients. Glomerular filtration rate was <90mL/min/1.73m2 in four patients (one of them with a pathologically increased urinary protein excretion). In three patients, abdominal ultrasound detected gallstones. The group of patients with antenatal Bartter syndrome had a lower renin ratio (P < 0.05) and a higher standard deviation score (SDS) for height (P < 0.05) than a previously studied group of patients with classical Bartter syndrome. Conclusions. Patients with Bartter syndrome type I and II tend to present a satisfactory prognosis after a median follow-up of more than 10years. Gallstones might represent a new complication of antenatal Bartter syndrom

Fatores contingenciais relacionados aos investimentos em pesquisa e desenvolvimento

Objetivo: O estudo tem por objetivo analisar os fatores contingenciais associados a decisões para investimentos em P&D em empresas familiares e não-familiares. Metodologia: A pesquisa foi realizada por meio de levantamento, sendo a amostra composta por 47 empresas do ramo industrial localizadas nos Estados da região Sul do Brasil. Das 47 empresas respondentes, 26 são familiares e 21 são caracterizadas como empresas não-familiares. As empresas são observadas a partir das características contingenciais: (i) quanto ao tempo de atividade, (ii) quantidade de colaboradores e (iii) estrutura de gestão – se empresas familiares ou não-familiares, e como tais fatores se relacionam com os investimentos em P&D. A análise foi realizada a partir das técnicas de estatísticas descritivas e de análise por meio do Teste Qui-Quadrado. Resultados: Os resultados evidenciam significância entre o tempo de atividade das empresas, o número de empregados e a estrutura de gestão, com a percepção de que os investimentos em P&D são necessários para a continuidade dos negócios. Identificou-se que as empresas com maior número de empregados (acima de mil) possuem maior interesse nos investimentos em P&D para a continuidade dos negócios. Empresas com tempo de atividade superior a 50 anos estão mais interessadas nos investimentos em P&D como estratégia de competitividade. A pandemia Covid-19 não interferiu nos investimentos em P&D na maioria das empresas da amostra. De forma geral, os resultados evidenciam que os fatores contingenciais relacionados à estrutura das organizações se relacionam com os investimentos em P&D, tanto nas empresas familiares como nas não-familiares. Contribuições do Estudo: Os achados sugerem que as empresas familiares (de maior porte e com maior número de funcionários) tendem a investir em P&D, tanto quanto as empresas não-familiares, visando se manterem competitivas. Tais resultados contribuem com reflexões e possibilidades de novos estudos acerca das especificidades das empresas familiares

Tissue distribution and acute toxicity of silver after single intravenous administration in mice: nano-specific and size-dependent effects

Background: Silver nanoparticles (AgNPs) are an important class of nanomaterials used as antimicrobial agents for a wide range of medical and industrial applications. However toxicity of AgNPs and impact of their physicochemical characteristics in in vivo models still need to be comprehensively characterized. The aim of this study was to investigate the effect of size and coating on tissue distribution and toxicity of AgNPs after intravenous administration in mice, and compare the results with those obtained after silver acetate administration. Methods: Male CD-1(ICR) mice were intravenously injected with AgNPs of different sizes (10 nm, 40 nm, 100 nm), citrate-or polyvinylpyrrolidone-coated, at a single dose of 10 mg/kg bw. An equivalent dose of silver ions was administered as silver acetate. Mice were euthanized 24 h after the treatment, and silver quantification by ICP-MS and histopathology were performed on spleen, liver, lungs, kidneys, brain, and blood. Results: For all particle sizes, regardless of their coating, the highest silver concentrations were found in the spleen and liver, followed by lung, kidney, and brain. Silver concentrations were significantly higher in the spleen, lung, kidney, brain, and blood of mice treated with 10 nm AgNPs than those treated with larger particles. Relevant toxic effects (midzonal hepatocellular necrosis, gall bladder hemorrhage) were found in mice treated with 10 nm AgNPs, while in mice treated with 40 nm and 100 nm AgNPs lesions were milder or negligible, respectively. In mice treated with silver acetate, silver concentrations were significantly lower in the spleen and lung, and higher in the kidney than in mice treated with 10 nm AgNPs, and a different target organ of toxicity was identified (kidney). Conclusions: Administration of the smallest (10 nm) nanoparticles resulted in enhanced silver tissue distribution and overt hepatobiliary toxicity compared to larger ones (40 and 100 nm), while coating had no relevant impact. Distinct patterns of tissue distribution and toxicity were observed after silver acetate administration. It is concluded that if AgNPs become systemically available, they behave differently from ionic silver, exerting distinct and size-dependent effects, strictly related to the nanoparticulate form
