La importancia de realizar estudios sobre el uso del forraje verde hidropónico de maíz (FVHM) es porque, se ha evaluado poco el impacto productivo y económico en la alimentación de los cerdos en la región de la Costa de Oaxaca. El objetivo del estudio fue evaluar el comportamiento productivo en cerdos en crecimiento con FVH como suplemento, con dietas a base de alimento comercial y con inclusión de FVHM. La investigación se realizó durante los meses de agosto a noviembre de 2017. Se evaluaron cuatro tratamientos [T1: testigo, T2: 85/15%; T3: 70/30% y T4: 55-45% de alimento comercia y FVHM respectivamente], bajo un diseño completamente al azar con cuatro repeticiones por tratamiento. Se utilizaron 16 cerdos desparasitados y vacunados, con peso inicial de 10.41 kg. Se evaluó consumo total de alimento (CTA), conversión alimenticia (CA), ganancia de peso total (GPT) y la relación costo-beneficio (RCB). Los datos obtenidos se analizaron mediante Proc.

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.

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.

Objective: The objective was to evaluate different scarification treatments to improve germination in chepil seeds

(Crotalaria longirostrata Hook. & Arn.). Design/Methodology/Approach: The study was established in the School of Veterinary Medicine and Zootechnics N. 2 of the Universidad Autónoma de Guerrero. The chepil seeds were weighed and counted; 2 experiments were established through a CRD with 4 treatments of 4 repetitions each. Imbibition and germination were evaluated. The data were analyzed with the statistical software package SAS® 9.0.

Productive response of creole lambs fed integral diets with Samanea saman (Jacq.) Merr. pods.

JERONIMO HERRERA PEREZ ULISES CARBAJAL MARQUEZ NICOLAS TORRES SALADO PAULINO SANCHEZ SANTILLAN OMAR RAMIREZ REYNOSO ADELAIDO RAFAEL ROJAS GARCIA MARCO ANTONIO AYALA MONTER (2021)

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.
