Equine leukoencephalomalacia @LEV, swine pulmonary oedema and human oesophageal cancer have been associated with fumonisine B1 (FB1) ingestion. For the first time in this study it is reported that FBI was identified as being associated with an outbreak of ELEM at Oaxaca, Mexico. Symptoms of ELEM and Equine Venezuelan Encephalitis (EVE) are s d a r and a different diagnosis is obhgatory. In the geographical area (Oaxaca, Mexico) where donkeys died showing a neurological syndrome, 14 corn samples were collected. With the use of TLC Thin layer chromatography) and HPLC (High performance liquid chromatography) all collected samples resulted positive to FB1. In the area of study, this syndrome was reported to be the cause of death of 100 donkeys, after 3 postmortem examinations in which macroscopic and yicroscopic cerebral white matter liquefactive necrosis were observed, when FBI concentration was determined in the samples collected, using HPLC and TLC. It was concluded that HPLC is a highly sensitive method for the detection of FB1 through the formation of an OPA derivative. However, the reverse phase TLC plate nad the visualisation of the coloured reaction with the vanillin acidic solution is more objective. FBI concentration in the studied samples ranged from 0.67 to 13.3 ppm. It was concluded that FB1 was the causae of leukoencephalomalacia reported in donkeys in the state of Oaxaca, Mexico.

________________________________________________________________________________ AbstractTo determine the effect of breed on growth performance and carcass characteristics in Mexican hair sheep, 48 lambs (average 38.9 ± 1.56 kg body weight, BW) were used in a completely randomized experimental design. The breed types assessed were 16 Pelibuey (PB), 16 Pelibuey x Katahdin (PB-KT) crossbred and 16 Pelibuey x Dorper (PB-DP) crossbred lambs. The lambs were fed a maize grain-based diet (88% concentrate and 12% forage) containing 155 g CP and 12.13 MJ ME/kg DM. The growth performance trial lasted 45 days. The average daily gain was significantly higher for the PB breed than for the PB-KT and PB-DP cross-breds. Feed intake in the PB and PB-KT was significantly higher than in the PB-DP. The feed conversion ratio was lower for the PB than for PB-KT and PB-DP lambs. Hot carcass dressing and leg perimeters were significantly lower for the PB than for the PB-DP lambs, and similar to that of the PB-KT lambs. The lowest dorsal fat values were measured in the PB breed, compared with both the PB-KT and PB-DP cross-breds. Mesenteric fat (as % of BW) in the PB was significantly higher than in PB-KT and PB-DP lambs. Empty rumen and small intestine weights (as % of BW) in the PB lambs were significantly higher than in the PB-DP lambs, but their large intestine was significantly smaller than in the other two breeds. It was concluded that the PB lambs have a better growth performance and carcass characteristics than the PB-DM lambs, but similar to that of the PB-KT lambs.________________________________________________________________________________

Oxidative status and fertility of ewes supplemented coffee pulp during estrous synchronization and early pregnancy ¤ Estado oxidativo y fertilidad en ovejas suplementadas con pulpa de café durante la sincronización estral y gestación tempranaEstado oxidativo e fertilidade nas ovelhas suplementadas com a polpa de café durante sincronização do estro e gestação inicial SummaryBackground: it is known that coffee pulp can modify the oxidative status and fertility in dairy cows. Objective: to evaluate the effect of dietary supplementation with coffee pulp on the antioxidant capacity, lipid oxidation and reproductive characteristics of ewes during estrous synchronization and early gestation. Methods: forty Dorset-Suffolk crossbred ewes with 3 or 4 parturitions were allocated to two treatments: T0 (n = 21), ewes supplemented with 450 g of a control feed; and T1 (n = 19), ewes supplemented with 450 g of the feed with 25% coffee pulp. Supplementation began 14 days before estrous synchronization and ended 25 days after breeding.

-The objective of the present study was to determine the nutritive value, the presence of antioxidant compounds, and the antioxidant capacity of coffee pulp ensiled or non-ensiled. Dry matter (DM), crude protein (CP), ash, acid detergent fiber (ADF), neutral detergent fiber (NDF), and lignin, as well as the antioxidant compounds present in coffee pulp and their antioxidant capacity, were determined. A completely randomized design was used. Data were analyzed by analysis of variance. Ensiling of coffee pulp increased the CP content from 98.6 to 111.6 g kg −1 DM, NDF from 414.6 to 519.5 g kg −1 DM, ADF from 383.9 to 439.3 g kg −1 DM, and lignin from 122.9 to 133.6 g kg −1 DM. Caffeine decreased from 5.72 to 5.02 mg g −1 DM. Three antioxidant compounds were detected. Caffeic acid decreased due to ensiling (16.49 vs 14.69 mg g −1 DM). Gallic acid (2.88 vs 2.58 mg g −1 DM) and chlorogenic acid (62.12 vs 56.00 mg g −1 DM) did not differ, and there was similar antioxidant capacity of non-ensiled (215.66 µmol trolox g −1 DM) and ensiled coffee pulp (206.59 µmol trolox g −1 DM). Despite the decrease in the caffeic acid content due to the ensiling process, it is possible to use either ensiled or non-ensiled coffee pulp for animal feeding because of its high antioxidant capacity.
