The problem of anthelmintic resistance in ovine trichostrongyles is growing tropical areas such as Chiapas, Mexico.Hair-sheep breeds are frequently used by farmers because their climate adaptation, however, incidence requires more sensitive methods diagnosis this region order to apply selective treatments.The aim study was evaluate vitro and vivo the relative efficacy three main anthelmintics control gastrointestinal nematodes (GIN) hair sheep.Naturally infected ewes lambs experimentally...
Ewes' genotype and physiological stage are important factors associated with gastrointestinal nematode infection. The aims were to evaluate the parasitic (fecal eggs count, FEC), health (anemia level, FAMACHA; packed cell volume, PCV; hemoglobin, HGB), productive response (live weight, LW; body condition score, BCS) of hair ewes managed under a selective deworming program levamisole (7.5 mg/kg live weight) at reproductive stages (not pregnant, NPW, n=17; between first second third gestation,...
Abstract The overall goal of this study was to estimate the prevalence gastrointestinal (GI) parasites in dogs city Villahermosa Tabasco, Mexico. population consisted 302 owned that had limited access public areas. A fecal sample collected from each animal and examined for GI by conventional macroscopic analysis centrifugal flotation. Fecal samples 80 (26.5%) contained parasites. Of these, 58 (19.2%) were positive helminths 22 (7.3%) protozoan At least seven parasitic species identified....
The use of Duddingtonia flagrans as a tool for the biological control gastrointestinal nematodes (GIN) is promising alternative to anthelmintics. chlamydospores D. are orally dosed and their thick cell wall gives them capacity resist digestion pass through tract (GIT). Chlamydospores reaching faeces able germinate trap nematode larvae. efficacy this method based on reducing numbers infective larvae leaving faeces. Techniques have recently been developed quantifying in As number non-digested...
Nematophagous fungi from the feces of water buffalo and soil southeastern Mexico were isolated, their in vitro predatory activity against Haemonchus contortus infective larvae (L3) (HcL3) was assessed. The isolated by sprinkling or on agar plates. Six series 10 Petri dishes containing a 7-day-old culture each fungus without as control prepared. Five hundred HcL3 added to plate. plates incubated at room temperature. average recovered considered estimate larval reduction rate. Four...
The aim of this study was to develop and evaluate equations predict body weight (BW) using heart girth (HG) in Pelibuey ewes. For model a data set composed by 366, 3-year-old, non-pregnant non-lactating ewes; with mean BW 45.7±9.16 kg HG 87.55± 7.93 cm used. A linear equation fitted: BW= -47.97 (±2.01*) + 1.07 (±0.02**)×HG (R2 = 0.86, RMSE 3.46, , y n 366). second 67 animals, similar characteristics (BW 38.25± 8.62 80.37± 7.03 cm) used the developed equations. evaluation, relationship...
Background Baseline hematologic data are used by veterinarians and wildlife biologists to perform health assessments on target animal species. Hematologic measurements influenced various factors including geography. RI s have been established for domestic water buffaloes ( Bubalus bubalis ) from countries in the Eastern Hemisphere, but these not readily available Western Hemisphere. Objective The aim of this study was determine values several commercial farms southern Mexico. Methods Blood...
Abstract The use of Duddingtonia flagrans in the control goat nematodes was investigated. Initially, time passage chlamydospores through digestive tract goats evaluated. Two groups seven parasite-free kids were formed. Group A received a single dose 3.5×10 6 D. (FTHO-8 strain) per kg live weight. B did not receive any chlamydospores. Faeces obtained from each kid daily day 4 prior to inoculation until 5 post-inoculation (PI) and placed Petri dishes containing water agar. Gastrointestinal...
This study was carried out to evaluate the residual feed intake (RFI), volatile fatty acid (VFA) production and enteric methane (CH4) from growing Pelibuey sheep. In this case, 12 non-castrated with an initial average live weight (LW) of 21.17 ± 3.87 kg age 3 months, were housed in individual pens fed a basal diet 16% crude protein 11 MJ ME for 45 days. Dry matter (DMI) measured daily gain (DWG) calculated using linear regression between LW experimental period. Mean metabolic (LW0.75)...
El objetivo fue evaluar los efectos de época y año nacimiento, tipo parto, sexo número parto sobre el crecimiento predestete la productividad las ovejas en ovinos raza Pelibuey que producen bajo un sistema semi-extensivo trópico húmedo México. Se usaron datos 323 a partir registros producción 2011-2017. evaluaron pesos al nacimiento (PN) destete (PD, 60 d), así como camada (PCD). Adicionalmente, se evaluó prolificidad, mortalidad hasta kilos cordero producido por oveja ciclo 240 días...
