Anestesi av det neonatala fölet
Every spring you can see newborn foals running on fields among the mare. But some unfortunate end up visiting the equine hospital requiring surgery. This is a challenge for the anesthetist because of the neonatal foal?s unique physiology. Therefore you need to take these differences under consideration when you anesthetize foals.
En pilotstudie av unghästars användning av ligghall i grupphållningssystem
Today, individual indoor stalls and individual outdoor paddocks are the most common way to house horses in Sweden. The way that we manage, house and feed the horses are not optimal for the species natural basic behavioural needs. However, the awareness of this grows in the context of research and the emergence of alternative housing systems. One of the alternatives to the traditional format in individual boxes is called group housing. Group housing systems allow horses to live in herds and they can choose how they want to distribute the hours of the day between movement, resting and foraging.
The purpose of this study is to examine how frequently the young horses in a group housing system use the indoor lying area.
Uppfödares syn på inridningshästar i grupphållning : enkätundersökning
The horses? natural behaviour is easier to satisfy in a loose-housing system than housed in a traditional box. Law?s and science suggest that we should house horses in loose-housing, which improve the horse possibility to perform natural behaviours, to interact socially with other horses and to have more possibility to movement. It?s more timesaving in a working population aspect and a economic gain in materials.
We noticed that it?s different opinions about what people in the horse society thinks about having youngsters housed in a loose-housing system.
Ligghallsareans inverkan på beteenden hos högdräktiga ston i lösdrift :
SUMMARY
This pilot study tried to answer the question however the present animal welfare regulations
for horses regarding lying hall area requirements are adequate for horses older than
24 months. The study was carried out at one of the largest stud farms for standard bred
horses in Sweden. Mares in late pregnancy with an initial mean age of 10 years was used
in a behaviour study. The influence of varying space per animal in a loose-housing system
on behaviours like the horses' lying hall use, standing, resting, moving behaviour and
threats was studied. The behaviour at three different horse densities ? 18 mares, 13 mares
and 8 mares (7.4 m2, 10.3 m2 and 16.7 m2 per mare, respectively) ? was recorded by use
of video.
The behaviour of foals before and after weaning in group
Weaning is a standard procedure at most studs, and the methods of weaning varies greatly. The method used at the stud in this particular study is supposed to decrease stress. The purpose of the study was to compare the behaviour of foals in group before and after stepwise removal of their mares.
Standardbred foals with their mothers were kept in three different groups at pasture (12, 11 and 11 foals, respectively, mixed sexes). They had free access to silage and the foals were fed concentrate in a creep-feeding area. By the time the foals were 5 months old, the mares were stepwise removed from the pasture.
Fodersammansättningens betydelse för tillväxt hos häst :
The aim of the present study was to investigate the effect on growth of foals on two different diets, either a forage-based diet or a diet containing approx. 40 % concentrate. The report also includes a review of the pertinent literature on the effects of diet on mares? milk and growth of horses. The hypothesis of the study was that a forage based diet will result in a similar growth pattern as a diet including more concentrates if the diets contain the same amount of energy, crude protein, lysine, calcium and phosphorous.
Avvänjningsmetodens påverkan på fölet : en naturligare avvänjning för ökat välmående
Den naturliga process där stoet avvänjer sitt föl strax innan hon ska föla igen ger den unga hästen möjlighet att gradvis ändra sitt val av föda och mogna till en självständig individ. Den tidigare och mer abrupta avvänjningen som ofta sker av domesticerade hästar är mycket stressande för fölet. Negativa effekter som kan ses är en ökad skaderisk, försämrat immunförsvar och utveckling av onormala beteenden som stereotypier. Eftersom hästägare och uppfödare vill ha friska och sunda hästar är det viktigt att börja med en god välfärd för fölet som kan ligga till grund för den framtida hästens välmående. Det finns i dagsläget studier som redovisar avvänjningsmetoder som orsakar fölet mer eller mindre stress.
Hur skiljer sig ston åt i försvaret mot endometrit?
Kvarstående betäckningsinducerad endometrit är ett stort problem inom hästnäringen och så även andra typer av endometrit. Detta är den främsta orsaken till infertilitet hos ston. Vissa ston är nämligen oförmögna att klara av den inflammatoriska reaktion som normalt följer av betäckning (för att eliminera sperma och patogener) eller så drabbas de lättare av kroniskt infektiös endometrit, oavsett betäckning. Det finns otaliga förslag till förklaringar till varför de inte kan hålla uterus fri från inflammation såsom defekta myometriekontraktioner, stoets reproduktionshistoria eller anatomiska aspekter (t.ex. pneumovagina, otillräckliga mekaniska barriärer eller en horisontell uterus).
Shelter use of horses during Swedish summer in relation to weather conditions and insect abundance
Outdoor housing of horses? best fulfils the horses? need for physical activity and it is an alternative to the more cost and energy demanding indoor housing in stables. Furthermore, if outdoor housed horses have access to shelter they can generally cope well with adverse
weather conditions such as high or low ambient temperature, heavy rain or strong winds.
In this study, the daytime shelter-seeking behaviour of three groups of horses housed outdoors was studied during the summer. The aim was to evaluate whether shelter use is related to weather variables (e.g., ambient temperature and wind speed) and insect harassment.
The shelter-seeking behaviour was studied for three different groups of horses: Group 1) eight individually housed horses in paddocks that had access to three different shelter types (C: closed on three sides with roof, R: open on three sides with roof, W: closed on three sides without roof), Group 2) 25 group housed mares with foals on pasture with access to shelters
C, and Group 3) ten mares without foals on pasture without access to shelter. Each group was studied for eight days.
