El objetivo de este estudio fue identificar la distribución partos a lo largo del año en vacas doble propósito Hacienda Yahualingo, ubicada Santa Bárbara, Guerrero, México. Se analizaron los datos nacimientos crías (n=400) mediante estadística descriptiva. Los resultados mostraron que mayor cantidad ocurrió enero 2019 y 2020 (16.23%, 13.79%), mayo 2021 (16.7%) septiembre 2022 (15.19%). En hacienda se han mantenido cruzamientos entre razas puras años (78.6%), (76.4%) (76.5%). La raza...
Using an Ekomilk Bond Total Ultrasonic Milk Analyzer, the physicochemical characteristics of milk from 10 herds and 237 samples were analyzed during rainy season (July August; 109 samples) dry (January February; 128 samples), providing following measures: fat (%), non-fat solids (NFSs; %), density (g/mL), freezing point (°C), acidity temperature lactose conductivity (mS/cm), pH water (%). In this study, there was a higher percentage (2.975 vs. 5.001%) (1033.692 1035.45 g/mL) in compared to...
High environmental temperatures cause heat stress in ewes, resulting thermoregulatory problems. In this study, the responses of Blackbelly adult ewes (G1, n = 14) and female lambs (G2, 7), during summer under tropical conditions, southern Mexico were analyzed. Different physiological variables skin (ST) recorded. Breathing frequency (BF) values similar between groups at 116.73 ± 33.598 bpm (G1) 113.661 34.515 (G2) (p > 0.05). case elasticity (SE), there no significant differences time day...
Two groups of ewes (10 lactating and 10 non-lactating) were used to evaluate the effect heat stress during summer under tropical conditions. In this study, a temperature humidity index (THI) was found that ranged between 65 79 (morning afternoon). Likewise, tolerance coefficient (HTC) 6 units observed. The highest breathing frequency (BF; 115.46 ± 35.25 breaths per minute (bpm)) rectal (RT; 38.95 0.51 °C) afternoon in group ewes. means compared by group, time day, interaction, only...
The aim of this study was to evaluate the intensity annual sexual behavior (SB) Boer bucks under tropical conditions in southern Mexico. For one year, 16 extensively grazing males were evaluated for SB individually with estrogenized goats. From beginning experiment and every 30 days, body weight (BW), condition (BC), testicular circumference (TC), odor (OI), (nudging, ano-genital sniffing, flehmen, mounting attempts, mounts intromission, self-urination) recorded. showed more intense during...
The present experiment aimed to evaluate the reproductive response of Blackbelly ewes synchronized with low doses eCG during summer in a tropical climate. Sixty multiparous hair were divided into three groups (20 ewes/group): control group (CG; 0 IU eCG), treated 1 (TG-1; 140 eCG) and 2 (TG-2; 300 eCG). study found that showed differences their behavior (P < 0.01). Indeed, all TG-1 TG-2 presented higher estrus than CG In same way, had an onset less time On other hand, prolificacy was also...
Objective. To determine whether Blackbelly ewes are affected by heat stress (HS) during the summer in a tropical climate. Materials and methods. In this experiment, 21 female were divided into two treatments (T1=7 lambs T2=14 multiparous ewes) to evaluate effect of HS through temperature humidity index (THI), physiological, hematological variables. Results. THI between 77 88 U was found. Likewise, respiratory rate (RR) higher T2 afternoon (117 bpm) than morning (114 (p<0.05). Also, rectal...

Objetivo. El presente estudio tuvo como objetivo evaluar el control de la papilomatosis bovina (PB) con vacuna autógena en condiciones del trópico Guerrero. Materiales y métodos. En experimento se usaron 18 hembras bovinas que fueron divididas tres tratamientos acuerdo al rancho (6 hembras/grupo). Tratamiento 1 (T1-inmunovacuna), tratamiento 2 (T2-histovacuna) 3 (T3-plasmaterapia). Resultados. Al inicio encontró una alta incidencia papilomas las [(T1 (190 papilomas), T2 (95 papilomas) T3...
Objetivo. Evaluar el efecto de tres promotores crecimiento sobre consumo alimento (CA) y ganancia diaria peso (GDP) en corderos pelo. Materiales métodos. Fueron asignados aleatoriamente 12 cuatro tratamientos con repeticiones cada uno: Tratamiento 1 control (T1-C; dieta basal), tratamiento 2 (T2; complementación 0.125 g clorhidrato zilpaterol (Zilmax®), 3 (T3; Clorhidrato Ractopamina (LAPI-RACTO®) 4 (T4; mg zeranol implantes) (Zearalenona-Ralgro®). Se utilizó un diseño estadístico bloques...
En el estado de Guerrero, la región Costa Grande, se localiza en trópico subhúmedo mexicano; lugar donde ganadería ovina es importante para sector agropecuario esta del país. Sin embargo, algunos factores riesgo que favorecen infestación por parasitosis gastrointestinales ovinos son los ambientales, manejo y medicina preventiva (González-Garduño et al., 2011). Los principales parásitos regiones tropicales nematodos como: Haemonchus contortus, Cooperia curticei, Trichostongylus colubriformis,...
En el estudio se evaluó la conducta ingestiva de corderos pelo finalizados en corral alimentados con rastrojo hoja mango. Doce fueron divididos dos grupos, G1 (6 corderos) dieta basal + 20 % maíz y G2 seca mango molida. El periodo alimentación duró 40 días cada tercer día midió por 8 horas continuas: alimentándose, bebiendo, buscan agua, echados, ociosos, rumiando (parados o echados), orinando, defecando acicalamiento individual, a un compañero conductas agonistas, así como, consumo rechazo...
Fueron caracterizados morfológicamente 12 corderos Blackbelly en pastoreo extensivo a través de ecuaciones regresión lineal y coeficiente determinación. Las características morfológicas los fueron obtenidas la medición del peso vivo (PV) mediciones corporales. Los datos morfológicos se ajustaron por variable un modelo usando el análisis regresión, registró ecuación En estudio encontró que las variables largo cuerpo (LC; 60.54%), distancia entre ojos (DO; 55.14%) circunferencia base cola...
En 12 corderos de pelo (2 grupos 6/c.u.) alimentados con rastrojo hoja seca mango molida se analizaron las características físicas del líquido ruminal y heces. El grupo 1 (G1) consistió en la dieta basal + 20 % maíz el 2 (G2) molida. experimento tuvo una duración 40 días los que evaluaron semanalmente Los datos programa estadístico SAS (2021), compararon medias entre prueba Ji-cuadrado Pearson. estudio encontró diferencia significativa (P<0.001). color heces siempre fue amarillo G1 café...
