Abstracts: 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 [Eficácia das medidas de controle da artrite encefalite caprina em rebanho leiteiro]. Resumo: Avaliou-se a eficácia das medidas de controle para a artrite-encefalite caprina em rebanho com 431 caprinos leiteiros em regime intensivo de criação. Todos os animais com idade superior a seis meses foram inicialmente testados por imunodifusão em gel de ágar (IDGA) e soropositivos e soronegativos separados. Durante dois anos e dez meses medidas de controle foram instituídas. Cinco testes sorológicos foram posteriormente realizados, dois por IDGA e três por Western Blot (WB). Nesses testes eram avaliados os animais negativos na sorologia anterior e acrescidos os com mais de seis meses, ainda não avaliados. A eficácia do controle foi avaliada pela incidência da enfermidade. Animais que soroconverteram foram estratificados quanto a idade, estado fisiológico e sorologia das progenitoras. Para o efeito do tempo foi realizado a regressão logística a 5% de significância, convertidos em razão de probabilidades. A incidência geral e incidência em função da idade e estado fisiológico foram avaliadas pela análise variância, comparando as médias pelo teste Tukey a 5 % de significância. O teste de proporções foi utilizado para incidência e estado fisiológico, e a concordância entre os testes IDGA e Wb realizada através do coeficiente Kappa. Os animais que soroconverteram e eram nascidos de progenitoras positivas foram comparados com aqueles de progenitoras negativas ao parto pelo teste de Qui-quadrado, assim como o número de animais descartados. Inicialmente identificou-se 54,24% (179/330) de animais positivos e 257 soroconverteram após início do controle. Incidências maiores ocorreram nos animais entre 13 e 36 meses e nas lactantes. Soroconversões em crias de progenitoras soropositivas foram maiores que nas de progenitoras soronegativas (p < 0,001). Altas taxas de infecção foram identificadas nos reprodutores. Os resultados obtidos não foram satisfatórios, pois as medidas não contribuíram para evitar novos casos, demonstrando que existem momentos de infecção que precisam ser elucidados. Nas propriedades que intencionam controlar a enfermidade, além das medidas já recomendadas, é necessário utilizar testes diagnósticos com menor periodicidade; teste de alta sensibilidade nos animais jovens; realizar imediata separação das crias das progenitoras ao nascimento; separar as crias de acordo com o status sorológico das progenitoras; incluir as crias provenientes de partos não acompanhados no grupo de crias de progenitoras positivas e manter animais positivos e negativos em propriedades diferentes ou com grande distanciamento. É importante avaliar, nos rebanhos em que há a intenção de se estabelecer um controle, se as perdas produtivas associadas a enfermidade são maiores que os custos da implementação de medidas mais eficientes.

Abstract: This study assessed animal welfare in ewes subjected to transcervical (TC) or laparotomy (LP) embryo collection, and the efficiency of these two techniques. Santa Inês ewes (n = 57) received a protocol for estrus synchronization and superovulation. Cervical dilation protocol was initiated 12 h before embryo collection in all ewes. Depending on the success of cervical passage, the embryos were collected from ewes by either TC or LP. Records were made of physiological (rectal temperature (RT) and heart rate (HR)), endocrine (cortisol concentration), biochemical (glycaemia, total proteins, globulin and albumin concentrations), and behavioral variables. Data were recorded before fasting (BF) and sedation (BS), during (DC) and immediately after embryo collection (IAC), and 1 h (1hAC), 3 h (3hAC), 6 h (6hAC), 12 h (12hAC), 24 h (24hAC), and 48 h (48hAC) after embryo collection. The LP and TC procedures were applied to 22 and 35 ewes (with 100.0% and 94.3% of procedures being successful, respectively). The use of LP took longer than TC (P = 0.007) but was less effective in the recovery of uterine fluid and structures (P = 0.0002 and P = 0.0180, respectively), with no difference in the number of viable embryos recovered per animal. The TC procedure induced a greater RT at DC (P = 0.002) and IAC moments (P < 0.0001). The heart rate was greater in TC than LP in IAC (P = 0.036). On the other hand, HR was greater with LP at 12hAC (P = 0.033) and 24hAC (P = 0.002). There was no interaction between the procedures and time on total proteins, albumin, or globulin concentrations. The TC procedure induced greater glycaemia than LP in IAC (P < 0.0001). LP induced greater serum cortisol concentration than TC at DC, IAC, 1hAC (P = 0.0004; P = 0.0006; P = 0.036, respectively), even though it was greater in the TC than the LP procedure at 3hAC (P = 0.008). In conclusion, the TC embryo collection was more effective than the traditional LP procedure. Although both embryo collection procedures affected ewes? welfare, the TC procedure is probably less stressor than the LP.
