“…The importance of the FAMACHA © system has been comprehensively reviewed (Van Wyk and Bath, 2002;Kaplan et al, 2004;Bath et al, 2005;Van Wyk 2005Kenyon et al, 2009) and has not only been tested in Southern Africa (Bath et al, 2001;Malan et al, 2001;Vatta et al, 2002) but also in many countries including North America and St Croix (Kaplan et al, 2004), Brazil (Sotomaior et al, 2003, Molento et al, 2004Vieira et al, 2008), the Thus sufficient parasites were being excreted onto the pasture in order for the groups to have a significant challenge and for the trial to be a good study of the effects of deworming schedules.…”

Much research has gone into developing a sustainable management tool for haemonchosis, namely the FAMACHA © system, which has been validated by numerous studies worldwide. However, the financial implications on production of implementing this system have not been fully There were no significant differences in body weight gains, FAMACHA © and body condition scores amongst the three treatment regimens for ewes that did not conceive.For those that became pregnant during the trial there was a significant difference when analysed by calendar date but not when analysed by reproductive stage. There were also no significant differences between trial groups in lamb birth weight and, after slow growers had been sold, the average daily gain of the lambs born to ewes in the trial. The cost of anthelmintics was considerably lower for the FAMACHA © group. In conclusion there were no significant differences in selected production parameters when using the FAMACHA © system as opposed to other methods of anthelmintic use in a Mutton Merino flock in a semi-intensive farming system 3 and that the gestation status should be taken into account when measuring these parameters in future studies.

“…En las variables CC y HGH se presentó una correlación negativa (r= -0.241; p≤0.01), es decir, corderos con baja CC presentan alto conteo de HGH. Morteo et al (2003) Las correlaciones en el presente trabajo fueron muy bajas debido a que los animales presentaron un bajo número de HGH, esto concuerda con estu dios (Malan et al, 2001;Van y Bath, 2002;Vatta et al, 2002;Kaplan et al, 2004) donde mencionan que una infestación parasitaria alta de estrongilos diges tivos se correlaciona negativamente con parámetros hematológicos como el valor de H, siendo un buen indicador de presencia de parásitos. Morales et al (2002) mencionan que los anima les con un elevado número de huevos en heces pre sentan niveles bajos de H.…”

La carga parasitaria gastrointestinal en ovinos (Ovis aries L.) es un factor que limita su producción en las zonas tropicales y subtropicales, ya que la aplicación de productos químicos para su control representa un alto costo. El objetivo de este estudio fue comparar la resistencia genética y alimenticia con la carga helmíntica en corderos de las razas Katahdin y Pelibuey en el sureste del trópico mexicano. Se utilizaron corderos Kata hdin y Pelibuey con media sangre de cruzas Dorper, de tres a cuatro me ses de edad, con un peso corporal de 20.09 ± 2.88 kg. Los tratamientos fueron: 1) Pelibuey con alta suplementación (PAS); 2) Pelibuey con baja suplementación (PBS); 3) Katahdin con alta suplementación (KAS) y 4) Katahdin con baja suplementación (KBS). La suplementación alta con sistió en 1% de su peso vivo en grano de maíz amarillo cada día; para la suplementación baja se suministraron 100 g del mismo grano por día. Se determinó la condición corporal (CC) y el índice FAMACHA mediante la prueba de Wilkoxon. Se evaluó ganancia diaria de peso (GDP), huevos por gramo de heces (HGH) y hematocrito (H); además se identificó el género de los parásitos gastrointestinales. Se utilizó un diseño completamente al azar con arreglo factorial 2 x 2. No se encontraron diferencias para ningu na variable por efecto de raza (p>0.05). Sin embargo, la suplementación afectó (p<0.01) la GDP: 4.64 ± 2.23 kg con alta suplementación y 2.43 ± 2.34 kg con baja suplementación. El H no mostró diferencias entre razas (p>0.05). La raza Katahdin fue más pesada que Pelibuey (p<0.0001): en KAS, el peso corporal fue de 22.96 + 0.36 kg; y en KBS fue de 22.06 + 0.33 kg. Los corderos con alta suplementación fueron más pesados que los que tuvieron baja suplementación (p<0.0001). En PAS, el peso corporal fue de 19.90 + 0.33 kg, y en PBS fue 17.70 + 0.38 kg. Se encontró correlación negativa (p=0.01) entre las variables CC-HGH (r=-.241) e índice FAMACHA HGH (r=-.198). Los únicos géneros presentes fueron Haemonchus spp. y Trichostrongylus spp.

“…FAMACHA is a system that measures anemia on the basis of the color of the lower eyelid mucous membrane in small ruminants, as a morbidity marker for Haemonchus contortus. FAMACHA could represent a good tool in targeting selective treatments in order to reduce anthelmintic usage [14,15]. Blood parameters are also important and reliable media for assessing the physiological and health status of animals [16].…”

Introduction\ud \ud The widespread use of conventional drugs in farm animals has resulted in anthelmintic resistance as well as the contamination of deleterious molecules in animal products and in the environment. Researchers are thus focusing on production systems that rely less on chemicals. The aim of this study was to monitor the gastrointestinal strongyle burden, blood count, body condition scores (BCS), and FAffa MAlan CHArt (FAMACHA) in a local Italian breed of sheep reared in natural conditions.\ud \ud Methods\ud \ud The study was carried out in a farm where homeopathy was utilised. Over a one-year period, faeces were sampled six times from ten Zerasca ewes to evaluate the fecal eggs count using a modified McMaster technique. At the same time, blood samples were collected to evaluate white blood cells, red blood cells, hemoglobin, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and red cell distribution width. BCS and FAMACHA were also recorded.\ud \ud Results\ud \ud Results showed low parasite levels in most of the samples with the highest value in the spring. Blood parameters were within the normal range, with significant fluctuations during the sampling period. BCS values corresponded to an adequate nutritional condition of the animals and FAMACHA scores did not suggest a worrying state of anemia.\ud \ud Conclusions\ud \ud In this farm, a thorough monitoring of the gastrointestinal parasite burden together with a BCS and FAMACHA evaluation allowed the amount of chemical treatments to be limited, normally administered twice a year without laboratory tests
