Malformations and reproductive problems are common in goats and sheep in Northeastern Brazil.
In this region with 18 million sheep and goats, losses due to malformations are nearly 520,000 kids and lambs.
Malformations and reproductive problems are observed in goats and sheep grazing Poincianella pyramidalis.

Poincianella pyramidalis is a cause of reproductive problems in sheep in Northeastern Brazil.
Abstract
Malformations have been observed in sheep and goats in the Brazilian semiarid region in areas where Poincianella pyramidalis is dominant. The objective of this trial was to determine whether Poincianella pyramidalis causes reproductive changes in pregnant sheep. Sixteen non-pregnant sheep were mated with two rams. After confirmation of the pregnancy by ultrasonography on the 18th day after mating, pregnant sheep were randomly divided into four groups (#1, 2, 3, and 4), with four animals each. Sheep received roughage in an amount equivalent to 2% of their body weight, mixed with 0%, 10%, 20% and 40% of dried leaves of P. pyramidalis for groups 1, 2, 3 and 4, respectively. In Groups 1 and 2, all animals lambed normally. In Group 3 (20% P. pyramidalis in the roughage), one lamb was born with arthrogryposis and three sheep gave birth to premature weak lambs within 128, 132, and 133 days of gestation. In Group 4 (40% P. pyramidalis in the roughage), one sheep lambed a normal lamb; another ewe had embryonic mortality after seven days of plant consumption, and two aborted on days 103 and 144 of pregnancy. One of the aborted fetuses was normal and the other showed arthrogryposis and prognathism. These results suggest that P. pyramidalis causes embryonic deaths, abortions, and malformations in sheep. 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.

Abstract: The manipulation of growth can be used as a strategy to reduce feeding costs. The objective of this study was to analyze, by deterministic and stochastic simulation, compensatory growth effects on the bioeconomic results of growing-finishing beef cattle systems. Four beef cattle systems were simulated with different feed restriction periods (no restriction, CONT; 90 days of restriction, COMP90; 120 days of restriction, COMP120; and 150 days of restriction, COMP150). Risk analysis was performed using the Monte Carlo method. Animals in feed restriction systems demonstrated partial compensation and required longer periods to achieve slaughter weight than CONT steers (16, 23 and 27 more days for COMP90, COMP120 and COMP150, respectively). The CONT system was the most productive (466 kg/ha/year), followed by COMP90 (443 kg/ha/year), COMP120 (432 kg/ha/year), and COMP150 (383 kg/ha/year). The most profitable system was the COMP90 system (US$ 161/ha) followed by the CONT (US$ 144/ha). The lower net margin was observed in the COMP120 (US$ 107/ha) and COMP150 (US$ 90/ha) systems. The risk analysis showed that COMP90 presented the highest financial stability. For all simulated systems, prices of finished steers, feeder calves, and corn were the variables with the greatest effects on net margin. The use of compensatory growth can be a tool to reduce feeding costs in beef cattle systems; however, the feed restriction must not be longer than three months. |
