#1 - Neonatal mortality associated with sodium monofluoracetate in kids fed with colostrum from goats ingesting Amorimia septentrionalis

Abstract in English:

Sudden deaths after colostrum ingestion in kids and lambs born to mothers grazing in areas with Amorimia septentrionalis have been reported in the Brazilian northeastern semi-arid region, in Paraíba state. This study aimed to determine whether the sodium monofluoracetate (MF) contained in A. septentrionalis is eliminated in milk, causing the death of kids. After confirming gestation on the 25th day after mating, 26 goats were randomly distributed into three groups. In Group 1, eight goats received fresh leaves of A. septentrionalis in daily doses of 1g/kg body weight, administered at three different periods during gestation: from days 91 to 100, 116 to 125, and from day 140 until delivery day. In Group 2, consisting of 10 females, eight goats received 1g/kg body weight of A. septentrionalis dried and milled leaves, fed daily from the 140th day of gestation until delivery. The other two goats of this group did not ingest the plant during gestation and after delivery the colostrum supplied to their kids was replaced by colostrum of goats from that same group that had ingested the plant. Eight goats from Group 3 (control) did not ingest A. septentrionalis. Seven goats from Group 1 showed signs of poisoning from 2nd to 8th days of plant administration, in all periods, and recovered within 7 to 12 days. Another goat presented severe clinical signs and was submitted to euthanasia in extremis. Two goats aborted. Four kids, from two goats, received colostrum and, after 15 minutes, presented depression, breathing wheezing, lateral recumbence, bleating, and death. Two goats gave birth at night; the two kids were found dead and, at necropsy, it was verified that they were born alive. The last goat in this group gave birth to two kids which showed no signs of poisoning after colostrum ingestion. In Group 2, the eight goats that ingested dry leaves of the plant presented tachycardia and engorgement of the jugular veins; six aborted, and the kids of the other two goats died immediately after delivery without ingesting colostrum. The three kids of the two goats that did not ingest the plant during gestation did not show signs of poisoning after ingesting colostrum from the goats that had ingested the plant. In Group 3, all females kidded normally and the kids showed no signs of poisoning. Ten leaf samples of A. septentrionalis contained 0.00074% ±0.00018 MF. These results demonstrate that the MF of A. septentrionalis is eliminated in colostrum and may cause the death of kids. As in previous reports, the plant also caused abortion.

Abstract in Portuguese:

Mortes súbitas, após a ingestão do colostro, em cabritos e cordeiros nascidos de mães que pastejam em áreas com Amorimia septentrionalis são relatadas no semiárido da Paraíba. O objetivo deste trabalho foi determinar se o monofluoracetato de sódio (MF) contido em Amorimia septentrionalis é eliminado pelo leite, causando a morte dos cabritos. Após a confirmação da gestação no 25º dia após a cobertura, 26 cabras foram aleatoriamente distribuídas em três grupos. No Grupo 1, oito cabras receberam folhas frescas de A. septentrionalis em doses diárias de 1g/kg de peso vivo, administradas em três períodos diferentes durante a gestação: entre os dias 91 a 100, 116 a 125 e do 140º dia até o parto. No Grupo 2, composto por 10 fêmeas, oito cabras receberam 1g/kg de peso vivo de folhas secas e trituradas de A. septentrionalis, fornecida diariamente do 140º dia de gestação até o parto. As outras duas cabras desse grupo não ingeriram a planta durante a gestação e, ao parirem, o colostro fornecido aos seus cabritos foi substituído pelo colostro de cabras, desse mesmo grupo, que ingeriram a planta. Oito cabras do Grupo 3 (controle) não ingeriram A. septentrionalis. Sete cabras do Grupo 1 apresentaram sinais de intoxicação entre o 2º e 8º dia de administração da planta, em todos os períodos, e se recuperavam em 7 a 12 dias. Outra apresentou sinais clínicos graves e foi eutanasiada in extremis. Duas cabras abortaram. Quatro cabritos, oriundos de duas cabras, receberam colostro e, após 15 minutos, apresentaram depressão, respiração ofegante, decúbito lateral, berros e morte. Dois cabritos, nascidos de duas cabras que pariram durante a noite, foram encontrados mortos e os achados de necropsia permitem afirmar que nasceram vivos. A outra cabra desse grupo pariu dois cabritos que, mesmo mamando o colostro, não apresentaram sinais de intoxicação. No Grupo 2, as oito cabras que ingeriram a planta seca apresentaram taquicardia e ingurgitamento das veias jugulares; seis abortaram e os cabritos das outras duas morreram imediatamente após o parto, sem ingerir colostro. Os três filhotes das duas cabras que não ingeriram a planta durante a gestação não apresentaram sinais de intoxicação após ter ingerido colostro das cabras que tinham ingerido a planta. No Grupo 3, todas as fêmeas pariram normalmente e os filhotes não apresentaram sinais de intoxicação. Dez amostras de folhas de A. septentrionalis continham 0,00074% ±0,00018 de MF. Estes resultados demonstram que o MF de A. septentrionalis, além de causar abortos, é eliminado pelo colostro podendo causar a morte dos cabritos.

Prof. Dr. Orlando Marques de Paiva 87, São Paulo, SP 05508 270, Brazil. E-mail: lgregory@usp.br Caprine Arthritis Encephalitis is a multisystemic infectious disease, caused by a lentivirus. The objective of this study was to evaluate the transmissibility of caprine lentivirus to goats and their offspring, through experimentally infected semen. Therefore, eleven free-CAEV goats were artificially inseminated using semen from a free-CAEV buck experimentally infected with CAEV-Cork strain (experimental group one). Pregnancy was confirmed in only six goats and their offspring (n=6) constituted the experimental group two. Two free-CAEV females were artificially inseminated with semen from the same seronegative buck, without viral inoculum to constitute the control group. The diagnosis of caprine lentivirus infection was performed using AGID, cELISA and nested-PCR. All females were monitored for 210 days after artificial insemination. Kids were immediately separated from their mothers after birth, and monitored at zero time, 15 days old and monthly until 12 months old. Regarding goat samples, 56.96% (9/159) were positive in cELISA, 24.05% (38/158) were positive in IDGA and none was positive in nested-PCR. Regarding to the offspring samples, 11.28% (15/133) and 5.26% (7/133) were positive in nested-PCR and IDGA, respectively, while no sample was positive in cELISA. The control group showed no positives in the three techniques. The positivity observed to nested-PCR may show its importance to identify infected, but seronegative animals, in late seroconversion situations. According to results, the transmission of caprine lentivirus to offspring and their mothers through infected semen is possible.

E-mail: lgregory@usp.br A Artrite Encefalite Caprina se caracteriza por ser multissistêmica e infecciosa, causada por um lentivírus. O estudo teve como objetivo avaliar a transmissibilidade do Lentivírus Caprino, para fêmeas e sua prole, por meio de sêmen infectado experimentalmente. Para tanto, onze fêmeas livres de CAEV foram inseminadas artificialmente com sêmen de bode livre de CAEV ao qual foi adicionado CAEV-Cork para obter título infectante com carga viral em 105 TCID50/ml. (grupo experimental 1). Destas, seis obtiverem prenhez confirmada, e a sua prole (n=6) constituiu o grupo experimental 2. Duas cabras livres de CAEV foram inseminadas artificialmente com sêmen do mesmo bode, sem o inócuo viral, constituindo-se o grupo controle. O diagnóstico da infecção pelo Lentivírus Caprino, foi realizado por IDGA, cELISA e nested-PCR. As fêmeas foram monitoradas durante 210 dias pós inseminação artificial. Já as proles foram imediatamente separadas das mães após o nascimento, e monitoradas nos momentos hora zero, aos quinze dias de idade e mensalmente, até doze meses de idade. Em relação às cabras, 56,96%(9/158) apresentaram positividade para cELISA, 24,05% (38/158) foram positivas a IDGA e nenhuma para nested-PCR. Em relação aos cabritos, 11,28% (15/133) amostras positivas para nested-PCR, 5,26% (7/133) amostras positivas para IDGA e nenhum para cELISA. As proles do grupo controle apresentaram resultados negativos para as três técnicas. A positividade encontrada em nested-PCR pode indicar grande importância para identificação de animais infectados, porém soronegativos, em situações de soroconversão tardia. De acordo com os resultados, concluiu-se que há a transmissão do Lentivírus caprino para a prole e para as mães pelo sêmen infectado.

E-mail: rolomonte@gmail.com The present study aimed to determine the occurrence of infection by Cryptosporidium spp. in goat kids from Quixadá, Ceará, Brazil. The study included 400 goat kids of both sexes, 3 to 360 days old, with or without defined breed, originating from 25 farms distributed in three circuits. Feces were registered in accordance with the appearance and color, distributed into tubes Eppendorf tubes and frozen in natura at-20°C until the moment of extraction of genomic DNA from the parasite with the aid of a commercial kit. For amplification of fragments of the 18S subunit of ribosomal RNA (rRNA) was used to Nested PCR. The occurrence of Cryptosporidium spp. in goats kids of the Quixadá was 7.50% (30/400). The frequency in the dry period and rainy was 9.55% (19/199) and 5.47% (11/201) respectively (χ2=2.39 and P>0.05). Positive samples were identified in 64.00% (16/25) of the studied farms, and from these samples 50.00% (15/30) and 70.00% (21/30) had feces with normal appearance and color respectively, suggesting that the asymptomatic goats were eliminating oocysts. No positivity for Cryptosporidium spp. was observed in 301 to 360-day-old goats, demonstrating that older animals have less chance to become infected with the parasite.

E-mail: afmedica@unizar.es Immunostimulants are susbstances that stimuli the response of effector cells to activate the immune response such as antigen uptake, cytokine release or antibody response. These substances can increase resistence to infection by different types of microorganisms, reducing dependence of antibiotics used in livestock animals. Recent reports have demonstrated the positive effect of Propionibacterium acnes (P. acnes) to control animal diseases. In this study, we evaluated the effect of the non-specific immunostimulant P. acnes on immunological functions and growth performance in goat kids. Twenty five goat kids served as control group (A) and another 25 animals received P. acnes being the experimental group (B). Kids were challenged with ovalbumin (OVA) to assess humoral immunity. To assess in vivo cell immunity, delayed type hypersensitivity (DTH) test with phytohemagglutinin (PHA) was used, clinical signs and body weight were recorded each week until 9 weeks of age when the experiment ended. Blood samples were obtained to analyze serum proteins fractions and anti-OVA specific antibodies. No clinical signs of disease and no differences (p>0.05) on body weight between groups were recorded (7.32±0.81 kg in group A, 7.13±0.65 kg in group B). Goat kids from group B had more total protein (59.8±5g/l) and albumin levels (32.8±3.3g/l) than goat kids from group A (56.6±5.7 g/l, 29.6±3.9 g/l respectively) (p<0.05). DTH response in goat kids from group B on day 42 was higher (p<0.05) than group A. At day 63, goat kids from group receiving P. acnes had higher percentage (85.4) of anti-OVA IgM titers (p<0.05) than control group (57.7). In conclusion, the results showed that oral administration of P. acnes to goat kids improved some aspects of the immune system of the animals and it could be used to control goat diseases.

E-mail: leydsonf@fmva.unesp.br After birth goat kids are dependent of colostrum immunoglobulins due to placental characteristics that don’t allow macromolecules passage from dam’s circulation. According to literature goat kids have colostrum immunoglobulin absorption capability for up to four days. Many physiological aspects of other species have been accepted and used for goats, but those related to passive immunity transference needs more investigation. The goals of the present study was to determine the period of macromolecules passage through gut wall to circulation until 36 hours postpartum and verify the duration of protective humoral immunity transferred by the ingestion of bovine and caprine colostrum. Sixty newborn goat kids were allocated into six treatment groups: T 0 (n=25), non-restricted natural ingestion of goat colostrum; T 1 (n=7), bovine colostrum from birth to two hours postpartum; T 2 (n=7), bovine colostrum ingestion between four to six hours after birth; T 3 (n=7), milk intake until the first eight hours and bovine colostrum administration between 10 to 12 hours postpartum; T 4 (n=7), milk ingestion for the first 18 hours and bovine colostrum ingestion between 22 and 24 hours after birth; T 5 (n=7), milk administration until 30 hours and bovine colostrum intake between 34 to 36 hours postpartum. The total protein (TP), gammaglobulin, immunoglobulin G (IgG) and gamma-glutamyltransferase (GGT) serum concentrations were determined. At birth all neonates presented lower values of the variables, with significant increase of TP and gammaglobulin at two days in groups T 0, T 1 and T 2, IgG and GGT increased in all groups. The treatments T 3, T 4 and T 5 were considered to induce failure of immunity passive transfer. The absorption of macromolecules by kid’s intestinal tract occurred until 36 hours postpartum, with better effectiveness until 12 hours. Antibody levels persist up to 75 days after bovine colostrum intake, but at this time their low concentrations doesn’t provide adequate protection.

Os objetivos do presente estudo foram determinar o período de passagem de macromoléculas da mucosa intestinal para a circulação e a duração da proteção humoral transferida passivamente pela ingestão de colostro bovino e caprino. Sessenta cabritos recém-nascidos foram distribuídos em seis tratamentos: T 0 (n=25), ingestão natural de colostro caprino à vontade; T 1 (n=7), colostro bovino entre o nascimento e duas horas pós-parto; T 2 (n=7), ingestão de colostro bovino entre quatro e seis horas pós-nascimento; T 3 (n=7), leite nas primeiras oito horas e colostro bovino entre 10 e 12 horas pós-parto; T 4 (n=7), ingestão de leite até 18 horas e colostro bovino entre 22 e 24 horas pós-nascimento; T 5 (n=7), leite até 30 horas e ingestão de colostro bovino entre 34 e 36 horas pós-parto. Determinaram-se as concentrações séricas de proteína total (PT), gamaglobulina, imunoglobulina G (IgG) e a atividade sérica de gama glutamiltransferase (GGT). Ao nascimento, todos os neonatos tiveram valores mais baixos das variáveis, com aumento significativo da PT e gamaglobulina, após dois dias, nos grupos T 0, T 1 e T 2; a IgG e GGT aumentaram em todos os grupos. Os tratamentos T 3, T 4 e T 5 foram considerados como indutores de falha de transferência de imunidade passiva. A absorção de macromoléculas pelo trato intestinal dos cabritos ocorreu até 36 horas pós-parto, sendo mais efetiva até 12 horas. Os níveis de anticorpos persistiram até 75 dias após a ingestão de colostro bovino, porém, com concentrações inadequadas.

Several changes occur in different organ systems including respiratory function and acid-base balance. The aim of this study was to hypothesize the occurrence of acidosis in newborn kids and obtain blood gas and acid-base parameters of kids in the first 24 hours of life. For this, 33 goat kids of both sexes were used. The blood samples were collected by jugular venipuncture immediately after birth, 5, 10, 15 minutes and 24 hours of life. The blood pH, oxygen partial pressure (pO2), carbon dioxide partial pressure (pCO2), total carbon dioxide (TCO2), bicarbonate concentration (HCO3), base excess (BE) and oxygen saturation (SO2) were determined with a portable blood gas analyzer. Significant differences were observed between the moments in all variables of the kids blood gas values. The newborn kids had respiratory acidosis during the immediate post-partum period, normalizing at 24 hours of life.

Centro de Saúde e Tecnologia Rural, Universidade Federal de Campina Grande, Campus de Patos, 58700-970 Patos, PB, Brazil. E-mail: riet@cstr.ufcg.edu.br The causes of perinatal kid mortality were studied from May 2002 to August 2004 in the semiarid region of Paraíba. In 118 necropsied kids the frequency of different causes of death were neonatal infections (50%), distocia (12.71%), hypothermia/starvation (11.86%), malformations (7.62%), floppy kid (6.77%) and abortions (1.69%). Regarding the time of death, 1.69% of the kids died before parturition, 16.94% during the parturition and 81.34 % after birth. The high occurrence of neonatal infections, dystocias, and hypothermia/starvation is probably to due to factors related with error in the sanitary, reproductive and nutritional management. Arthrogryposis of the forelimbs was the main malformation observed. This defect is endemic in goat flocks in the semi-arid of Brazil. Most deaths occurred after birth (25.42%) and from the 4th to the 28th day of life (38.98%) suggesting that care with the kids during their first 28 days of life is important for the improvement of the survival rate.

Centro de Saúde e Tecnologia Rural, Universidade Federal de Campina Grande, Campus de Patos, 58700-970 Patos, PB, Brazil. E-mail: riet@cstr.ufcg.edu.br The causes of perinatal kid mortality were studied from May 2002 to August 2004 in the semiarid region of Paraíba. In 118 necropsied kids the frequency of different causes of death were neonatal infections (50%), distocia (12.71%), hypothermia/starvation (11.86%), malformations (7.62%), floppy kid (6.77%) and abortions (1.69%). Regarding the time of death, 1.69% of the kids died before parturition, 16.94% during the parturition and 81.34 % after birth. The high occurrence of neonatal infections, dystocias, and hypothermia/starvation is probably to due to factors related with error in the sanitary, reproductive and nutritional management. Arthrogryposis of the forelimbs was the main malformation observed. This defect is endemic in goat flocks in the semi-arid of Brazil. Most deaths occurred after birth (25.42%) and from the 4th to the 28th day of life (38.98%) suggesting that care with the kids during their first 28 days of life is important for the improvement of the survival rate.

Pesquisa Veterinária Brasileira 25(4):219-224. Centro de Ciências Agrárias, UFPB, Campus III, Areia, PB 58397-000, Brazil. E-mail: saravilar@bol.com.br The experiment was performed to determine the kid management that ensures the best passive immunity, and to evaluate the relationship between passive immunity, neonatal morbidity and performance. Blood samples were obtained from 58 Saanen kids before colostrum ingestion and 30h after. The kids were submitted to five treatments: (T1) kids were allowed to nurse the dam for 24 hours ingesting colostrum ad libitum; (T2) kids were bottle-fed with 200mL colostrum in the first hour of life; (T3) kids were bottle-fed with 400 mL colostrum, 200mL in the first hour and 200mL 8 hours after birth; (T4) kids were bottle-fed with 400mL colostrum, 200mL in the first hour and 200mL 14 hours after birth; (T5) kids were bottle-fed with 600mL of colostrum, 200mL in the first hour, 200ml 12 hours after birth, and 200mL at 24 hours of life. Serum levels of gamaglobulins were determined by electrophoresis. The occurrence of diseases was monitored from birth to 28 days. Daily weight gains were used to evaluate the performance until weaning. The lowest concentration of g-globulin was observed in Group 2 (1,57g/dL) and the highest in Group 3 (2,60g/dL). In spite of higher levels of passive immunity Group 3 showed more animals with scours, however no statistical differences were observed. The immune status at 30 hours postpartum was not associated with neonatal weight gain.
