“…Souza et al (2015) O sucesso parcial de vários programas de controle da AEC indica que os testes disponíveis para diagnóstico dessa doença e as medidas de contenção comumente adotadas são úteis para reduzir a prevalência da infecção (Peterhans et al, 2004), mas não para a sua erradicação. Pérez et al (2013), Rodrigues et al (2018) e Tavella et al (2018), com a implementação de programas estratégicos de controle das LVPR em ovinos e caprinos, conseguiram reduzir significativamente os níveis de animais soropositivos e eliminar os sintomas clínicos no rebanho, mas não conseguiram zerar a incidência sorológica.…”

RESUMO Objetivou-se avaliar um programa de controle da artrite encefalite caprina (AEC), por meio de testes diagnósticos sensíveis, separação de mãe e cria após o parto e medidas de manejo, com o intuito de formar rebanho livre do vírus. Utilizou-se um total de 47 cabritos da raça Saanen, mantidos isoladamente até o resultado dos primeiros testes de reação em cadeia de polimerase nested (PCR nested) e Western Blotting (WB), com base na coleta de sangue no momento do nascimento (M0). No PCR nested, quatro animais foram positivos, no M0, e foram eutanasiados. Posteriormente, os demais 43 cabritos foram submetidos à coleta de sangue aos 60 (M60) e 270 (M270) dias de vida para realização de novos testes de WB e PCR nested, que não detectaram animais positivos. Pode-se afirmar que a metodologia adotada neste estudo foi efetiva no controle da doença, nas fases de aleitamento e pós-aleitamento, e que a combinação do sistema de manejo, a fim de propiciar diminuição de risco de transmissão horizontal, com técnicas de diagnóstico mais apuradas, como o WB e a PCR nested, é relevante para elaboração de plano estratégico de controle da enfermidade.

“…Therefore, it is pivotal to identify the most important diseases in the respective region and adopt a diagnostic routine. RODRIGUES et al (2018) evaluated the periodic use of more sensitive diagnostic tests combined with management practices while focusing on controlling caprine encephalitis arthritis. Although the disease was not eradicated, prophylactic management practices combined with periodic serological tests and polymerase chain reaction were decisive in significantly reducing the number of seropositive animals in the herd.…”

Biosecurity in dairy goat farms

et al. 2022

View full text Add to dashboard Cite

The goat milk industry has unquestionably grown in recent years due to the high demand for dairy products, which are considered nutritious and hypoallergenic. As a result, security measures are required in the production chain to provide consumers with safe products, although the concept of biosecurity is still incipient in Brazilian goat farming. Therefore, this study aimed to review the main biosecurity measures applied to dairy goat farms and suggest a program that contemplates these measures to promote animal health and welfare, given that biosecurity bolsters environmental sustainability and improves this agricultural sector. Biosecurity programs (BP) are composed of a set of measures and procedures aimed at herd health and applied in all stages of animal husbandry, interacting with different sectors that make up the production system and providing a set of policies and operational norms to protect herds against potentially pathogenic agents. Thus, BP require planning, execution, monitoring, audits, updates, understanding of the procedures, and awareness of those involved in the production chain. In addition, it includes continuing education programs and the development of contingency plans for specific emergencies. The information included in this study provides input to dairy goat farms to implement practices that improve the productivity of this agricultural sector.

“…Some studies have shown the economic losses associated with the disease and its risk factors (Alves et al, 2017;Rizzo et al, 2018). In Brazil, only two studies have been found on control methods in naturally infected herds (Stachissini et al, 2007;Rodrigues et al, 2018). In other countries where the occurrence of CAE is also worrying, studies have been developed aiming at the control and/or eradication of the disease (Péretz, Bugnard, & Calavas, 1994;Nord, Løken, & Orten, 1998;Kaba et al, 2011;Konishi et al, 2011;Gufler, 2013;Tavella et al, 2017).…”

This study examined the effectiveness of control measures for caprine arthritis-encephalitis in a herd with 431 dairy goats in an intensive rearing system. All animals older than six months were initially tested by agar gel immunodiffusion (AGID) and separated into seropositive and seronegative. Control measures were implemented for two years and ten months. Five serological examinations were subsequently performed two by AGID and three by the Western Blot (WB) technique. In these tests, animals that tested negative in the previous serological examination were evaluated along with those older than six months which had not yet been examined. The effectiveness of control was evaluated based on the incidence of the disease. Seroconverted animals were stratified according to age, physiological status and dam serology. For the effect of time, logistic regression was performed at the 5% significance level, with values converted into likelihood. General incidence and incidence as a function of age and physiological status were evaluated by analysis of variance, with means compared by Tukey’s test at 5% significance. The ratio test was used for incidence and physiological status, and the agreement between the AGID and WB tests was determined by the Kappa coefficient. Animals that seroconverted and were born to positive dams were compared with those born to dams negative at birth by the Chi-square test, and the same was applied for the number of discarded animals. Initially, 54.24% (179/330) positive and 257 seroconverted animals were identified after the start of control. Higher incidence occurred in the animals aged between 13 and 36 months and in lactating does. Seroconversions among offspring of seropositive dams were higher than in the offspring of seronegative dams (p < 0.001). High infection rates were identified in the sires. The obtained results were not satisfactory, as the measures did not help to prevent new cases, indicating that there are moments of infection yet to be elucidated. On farms that aim to control the disease, the following measures are required in addition to those already recommended: use of diagnostic tests with less frequency; application of high-sensitivity tests in the offspring; immediate separation of kids from dams at birth; separation of kids according to the serological status of the dams; inclusion of kids from unsupervised births in the group of kids from positive dams; and keeping positive and negative animals on different farms or greatly distanced. In herds for which there is an intention to establish control, it is important to determine whether the productive losses associated with the disease are greater than the costs of implementing more efficient measures.
