La genética es un factor que influye en el temperamento animal. El objetivo de este trabajo fue comparar la respuesta a tres pruebas vacas Holando neozelandesas (NZ) y norteamericanas (NA) bajo dos estrategias alimentación. Ciento veinte Unidad Experimental del Instituto Nacional Investigación Agropecuaria (INIA, Uruguay) fueron agrupadas una combinación orígenes genéticos: NZ o NA, con alimentación: Máximo pasto Pasto fijo. reactividad al ordeñe (RO), velocidad fuga distancia (DF) evaluadas...
Adaptative responses of cows to an automatic milking system (AMS) could depend on their temperament, i.e., with certain temperament profiles be able cope more successfully the AMS. The relationships between dairy cows' behaviour, and productive parameters during changeover from a conventional (CMS) AMS were investigated. Thirty-three multiparous classified as 'calm' or 'reactive' based each tests conducted: race time, flight speed (FS), distance, at 5, 25, 45 days in milk CMS, then moved CMS...
Pampas deer, Ozotoceros bezoarticus (Linnaeus 1758), is a South American grazing deer categorized as "near threatened". However, knowledge about pampas behavior including courtship and mating scarce incomplete. The aim of this study was to characterize the (Ozotoceros bezoarticus), an endangered species from America. We performed focal observations 5 males allocated at Estación de Cría Fauna Autóctona Cerro Pan Azúcar, Uruguay, 4 times day 20 minutes each time on daily basis February May....
The objective of the present study was to evaluate productive performance and grazing behavior 25 primiparous 44 multiparous Holstein cows in a pasture-based automatic milking system (AMS) while experiencing heat stress (defined as temperature-humidity index [THI] ≥ 68). Productive traits were analyzed according THI from days 0, -1, -2, -3 relation day, behaviors (expressed percentage daily observation time) related average only on day observation. Milk yield not associated with but...
Abstract In this Research Communication we investigate the motivations of Brazilian dairy farmers to adopt automated behaviour recording and analysis systems (ABRS) their attitudes towards alerts that are issued. Thirty-eight participated in study distributed into two groups, ABRS users (USERS, n = 16) non-users (NON-USERS, 22). USERS group 16 accepted being interviewed, answering a semi-structured interview conducted by telephone, answers were transcribed codified. NON-USERS group, 22...
Increasing the provision of non-fibrous carbohydrates (NFC) during prepartum period is a feeding strategy that has been recommended to facilitate transition onset lactation and improve dairy cow performance, but results are contradictory, probably because most studies have confounded effects level source energy. The objective this experiment was evaluate effect carbohydrate offered in diet on postpartum performance. Holstein cows (n=24) were assigned receive diets with either low (LNFC), or...
Abstract The flight distance from humans and the reaction of mother to human handling their offspring are measures that can be used assess quality human-animal relationship which could vary according animals’ position in a group. objective was determine if mother's her fawn during first 24 h after birth differ pampas deer ( Ozotoceros bezoarticus ) hinds’ social rank. A complementary aim compare mothers’ fawns being handled relative its sex. Studies were carried out on semi-captive...
Context Heat stress (HS) has a negative effect on milk production and the final period of gestation. There is almost no information HS dairy cows with temperature–humidity index (THI) less than 72 more 68. Aim Determine voluntary access to shade during dry physiological parameters subsequent postpartum performance Holstein cows. Methods Twenty-six multiparous were used in randomised complete-block design evaluate two treatments: without (CON) (SHA) for 62 ± 5.3 days before calving. During...
Factores relacionados con el animal y ambiente pueden afectar la frecuencia de mastitis, siendo genética estrategia alimentación algunos dichos factores. El objetivo este estudio fue analizar mastitis clínica los recuentos células somáticas (RCS) vacas Holando dos biotipos, Norteamericano (NA) Neozelandés (NZ), bajo estrategias (pastura o mixto). En Unidad Experimental Lechería INIA La Estanzuela (Colonia, Uruguay) fueron agrupadas 120 en 4 tratamientos según combinación biotipo (n=30)....
El objetivo del trabajo fue determinar la eficiencia de tres herramientas para detección celo en vaquillonas Holando. Treinta y cuatro Holando (sincronizadas con dos dosis Prostaglandina F2α, administradas un intervalo 11 días) fueron evaluadas. Se registraron todos los comportamientos (COMPORTAMIENTO) el porcentaje desgaste las etiquetas detectoras monta (PARCHE) veces al día, durante 30 minutos, por una semana. Simultáneamente, actividad animales monitoreada a través collares que miden...
