Methanogenesis is part of the energetic metabolism of ruminants, however there are legumes that have specific characteristics, which help reduce the production of anthropogenic methane. The objective was to determine the in vitro greenhouse gas (GHG) production of tree legumes from the Mexican dry tropics.

ADELAIDO RAFAEL ROJAS GARCIA MARIA DE LOS ANGELES MALDONADO PERALTA PAULINO SANCHEZ SANTILLAN PERPETUO ALVAREZ VAZQUEZ (2020)

The objective was to evaluate an analysis of growth of grass Mulato II (hybrid Urochloa) by varying the intensity and obtaining the optimal cutting moment in the dry and rainy season. The evaluated variables were: forage yield, morphological composition, plant density, plant height and intercepted relationship. The best dry matter yieldwas obtained at 56 days in rain, at an intensity of 15 cm, 1,820 kg DM ha-1andthe lowest at 7 days of regrowth in the dry season, with intensity 10 cm and a yield of 200 kg DM ha-1. The highest plant density was in the dry season

and lowest in rain with 9.5 and 8.5 plants m-2, respectively. 95% of intercepted radiation was obtained at 70 cm of plant height, in the rainy season, at 15 cm of cutting intensity and with 42 days of regrowth.

DEGRADACIÓN DE SUSTRATOS LIGNOCELULÓSICOS Y PRODUCCIÓN DE BIOGÁS in vitro POR FERMENTACIÓN SÓLIDA CON Pleurotus ostreatus.

JERONIMO HERRERA PEREZ PAULINO SANCHEZ SANTILLAN NICOLAS TORRES SALADO MARCO ANTONIO AYALA MONTER DIEGO FELIPE PORTELA DIAZ DANIEL HERNANDEZ VALENZUELA (2020)

Agricultural residues and hay pastures with more than 150 d of regrowth are characterized by their high fiber content; Pleurotus ostreatus digests lignin, cellulose and hemicellulose. The hypothesis of this study was that Pleurotus ostreatus improves the chemical characteristics and nutritional value of crop residues and pasture for animal feeding. The objective was to determine the chemical characteristics of nutritional value, biogas production and in vitro degradation of corn stubble and mulatto grass (Brachiariahybrid) treated with the MR and P15 strains of P. ostreatus for

15 and 30 d in solid fermentation.

Comportamiento productivo y calidad de pastos híbridos de Urochloa y estrella pastoreados con bovinos.

NICOLAS TORRES SALADO ADELAIDO RAFAEL ROJAS GARCIA MARIA DE LOS ANGELES MALDONADO PERALTA ARMANDO GOMEZ VAZQUEZ PAULINO SANCHEZ SANTILLAN (2020)

En las zonas tropicales, las gramíneas son la principal fuente de alimentación para los rumiantes, sin embargo, las condiciones ambientales y el manejo de las praderas inciden directamente en el rendimiento y calidad de las mismas. El objetivo fue estudiar el efecto del rendimiento de los pastos híbridos de Urochloa y pasto Estrella (Cynodon plectostachyus) a diferentes frecuencias e intensidades de pastoreo, con bovinos en el trópico seco. Se evaluaron los pastos Cobra, Mulato II y Cayman (Urochloa) y pasto estrella en frecuencias de corte de 28 y 35 d, e intensidades severo y ligero de 10 y 15 cm, respectivamente, que se distribuyeron de forma aleatoria en un diseño de bloques al azar con arreglo factorial 2 x 2 con tres repeticiones. Se observó efecto del manejo en la acumulación de MS, siendo mayor la acumulación a menor frecuencia e intensidad ligera de pastoreo independientemente del pasto evaluado.

Objective: To evaluate the productive behavior of Creole sheep in the tropics fed a whole food diet that includes soybean (FS, Glycine max) fodder at different phenological stages.Methodology: The treatments T1: control, T2: 30% (SF-56 d), T3: 30% (SF-68 d), T4: 30% (SF-85 d), T5: 30% (SF-110 d) were assigned randomly to 30 male Creole sheep (15.51¿1.6 kg LW). The experiment lasted 56 d. The variables evaluated were: dry matter intake (DMI), daily weight gain (DWG) and feed conversion (FC). The experimental design was completely randomized and the averages of the treatments were compared using the Tukey test.

Ruminant production in the tropics is based primarily on native and introduced grass (Poaceae) grazing. The effect of the regrowth age and cutting intensity of Brachiaria hybrid cv Cobra grass was evaluated, and the nutritional value when varying the frequency and intensity of 10 and 15 cm of cutting in the dry season. The study period was from January 19 to March 30, 2017. The variables were dry matter yield, morphological composition, raw protein (RP), neutral detergent fiber (NDF), and acid detergent fiber (ADF). The highest yield was obtained after 56 days in the intensity of 15 cm with 2550 kg MS ha¿1; however, the highest volume of leaves was reached at 35 days with 1200 kg MS ha¿1. The maximum content of Cobra grass RP was in the frequency at seven days with 19.3% in the leaf

component, decreasing as the evaluation time went by. The NDF and ADF content increased with the age of the regrowth.

Objective: To evaluate the productive variables and the digestibility of the nutrients of an integral diet for lambs with

increasing inclusion of Samanea saman pods. Design/methodology/approach: 24 creole lambs (initial weight of 20.6¿0.3 kg) distributed in a completely randomized experimental design were used. The treatments were: T1, 0%, T2, 12.5%, and T3, 25% of Samanea saman pod inclusion. The productive variables and the digestibility of the nutrients were evaluated and compared with the Tukey test (¿¿0.05); meanwhile, the response to the increasing content of Samanea saman was evaluated by orthogonal contrasts. The variables dry matter intake (DMI), daily weight gain (DWG) and feed conversion (FC) showed no differences (p¿0.05)between treatments.
