Craniofacial anomalies, eye malformations, and permanent flexures of the forelimbs are common malformations seen in ruminants grazing semiarid rangelands of Northeastern Brazil. To investigate the cause of these malformations, we fed 2 suspected plants, Mimosa tenuiflora or Prosopis juliflora, to groups of 4 pregnant goats each. Fresh green M. tenuiflora was collected daily and fed ad libitum to 4 goats in group 1 throughout pregnancy. This treatment group also received a supplemental feed… Expand
Congenital malformations and other reproductive losses in goats due to poisoning by Poincianella pyramidalis (Tul.) L.P. Queiroz (=Caesalpinia pyramidalis Tul.).
TLDR
It is demonstrated that P. pyramidalis causes congenital malformations and other reproductive losses in goats. Expand
Teratogenicity of Mimosa tenuiflora seeds to pregnant rats.
TLDR
It is concluded that the seeds of M. tenuiflora are teratogenic to rat fetuses and the weight and number of ossification centers of the fetuses from the experimental group were higher than those from the control group. Expand
Embryonic mortality and abortion in goats caused by ingestion of Poincianella pyramidalis
TLDR
It is suggested that P. pyramidalis, which is very common in the semiarid region of northeastern Brazil, should be considered as an important cause of reproductive losses in this area. Expand
Malformações congênitas em ruminantes no semiárido do Nordeste Brasileiro
TLDR
The highest frequency in sheep seems to be associated with the consumption of the plant by ewes after first rains, in the first two months of gestation, when they are supplemented with concentrates, and M. tenuiflora is the main green forage available. Expand
Reproductive losses caused by the ingestion of Poincianella pyramidalis in sheep
TLDR
Grazing pregnant sheep in areas where this plant is dominant should be avoided, and roughage for confined pregnant females should not contain more than 10% P. pyramidalis. Expand
Embryonic death in goats caused by the ingestion of Mimosa tenuiflora.
TLDR
It is concluded that M. tenuiflora causes embryonic death and the failure to induce malformations might have resulted from a high dose of an unknown active principle of the plant causing fetal death. Expand
Malformações, abortos e mortalidade embrionária em ovinos causada pela ingestão de Mimosa tenuiflora (Leguminosae)
TLDR
It is concluded that M. tenuiflora cause malformations, embryonic mortality and abortion in sheep. Expand
Avaliação da toxicidade das favas de Stryphnodendron fissuratum (Mimosoideae) em vacas gestantes
TLDR
The results presented herein confirmed the toxicity of S. fissuratum to bovines, however, the abortive effects of this plant was not confirmed; thus the abortion and neonatal deaths could be due to theoxicity of the pods to the cows. Expand
A review of poisonous plants that cause reproductive failure and malformations in the ruminants of Brazil
TLDR
A report on toxic plants causing reproductive problems in ruminants in Brazil finds that Aspidosperma pyrifolium causes abortion or stillbirth in goats, as well as most likely in sheep and cattle, in the semiarid regions of Northeastern Brazil. Expand
Utilização de vagens de Prosopis juliflora na alimentação de ovinos e caprinos
TLDR
P. juliflora pods, despite their toxicity, can be used to feed cattle at concentrations of 30% of the food during one year, and it is suggested that there is a loss in the capacity of the pods to form phytobezoars after harvesting. Expand

Mortalidade perinatal de cordeiros no semi-árido da Paraíba
TLDR
Considering that in the northeastern region, in most farms, the rams stay with the ewes during the whole year, the adoption of a breeding season would help to control the different causes of perinatal lamb mortality, the authors demonstrated the teratogenic effects of Mimosa tenuiflora, a very common plant in the semiarid region, which is probably the cause of malformations.

TLDR
The characteristics of the disease, which already has been diagnosed in Paraiba and occurs probably in other states of Brazil, are shown so that veterinarians and research workers could recognize it and give informations, which may clarify its etiology and pathogenic aspects. Expand
