Chewing behaviour of growing cattle

Chewing behaviour includes both eating and ruminating activity. Chewing behaviour is of great importance for the feed intake as through the action of chewing (i.e. eating and ruminating) animals mechanically process the forages in small particle sizes and prepare the food for digestion. As cattle grow the Chewing behaviour changes along with increasing body weight and chewing efficiency is increased. The aim of this thesis was to review the available scientific literature in order to describe Chewing behaviour in growing cattle, as well as the factors that affect this behaviour.

Hackelselängdens betydelse för tuggtid och foderkonsumtion hos mjölkkor :

Today, our cows experience a harder pressure to achieve higher milk yield. To manage this challenge the animal needs first class feeding and treatment. An important aspect of the feeding is to fulfil the need from the cows of especially fiber; and fiber with a sufficient proportion of long particles. Both too much and too little fiber is bad for the wellbeing of the cow, and she might get diseases like acidosis. Many models for feed management have been developed to secure that the animal gets enough of e.g. fiber with a sufficient proportion of long particles.

Normering av en objektiv metod för att mäta käkrörelser med 3D-videoanalys vid tuggning samt en jämförelse mellan käkens rörelseomfång vid tuggning och tuggeffektivitet hos unga vuxna

This study aims at norming a new objective method to track and measure jaw movements in 3D (three dimensional) during chewing in the young adult population (n=41, age 22-30). Norm values of the range of movements and the duration were calculated. Intra and inter rater reliability was high. Masticatory efficiency among participants was evaluated with a two-colored wax, analyzed with picture analysis software. Regression analysis was used to calculate the relationship between movement and duration variables and masticatory efficiency.

Vallfoder till slaktgrisar : effekter på tillväxt och social beteende vid utfodring

The aims with the project were to investigate how forage consumption affect production and pigs behaviour around the feeding. This degree project was designed to follow 48 growing/finishing Hampshire*Yorkshire pigs, from 30-110 kg live weight, fed diets with or without 20 % forage inclusion. The pigs were divided in three groups due to dietary treatment. In the first group the pigs were fed 20 % of the energy in the feed ration by long grass/clover silage (LE) and the remaining 80 % by a cereal concentrate. Group two was fed chopped grass/clover silage mixed with cereal concentrate (HE) in the same amounts as LE.

Behövs kattetologer på djursjukhus i Sverige? :

Behaviour problems are often behaviours that cat owners don´t like, but are normal to the cat. The reason to why cat owners experience certain feline behaviours as problematic is probably due to the current practice in cat housing. The ways that cats are kept today causes somewhat of a compromise between cat and owner and inhibits the expressions of the cat's natural and normal behaviour. The cat owners may misunderstand their cats behaviour, for example the cat owners believe that their cats perform certain behaviours because of feelings of guilt, hate, revenge or maybe to protest against something or someone. An animal hospital may help solve behaviour problems, but also help the cat owners to undstand their cat´s behaviour in an other perspective. The aim of this study is to investigate the need of a cat ethologist in animal hospitals.

In 2008, 35% of theworld's population were overweight and 11% obese , which is almost doubling since 1980,according to WHO. Recommendations on overweight and obesity is not just about what weeat but how we eat. A generally accepted recommendation is to eat slowly and chew yourfood properly in order to increase fullness and reduce energy intake.

Maternal behaviour in pigs and its relation to piglet performance and survival

Piglet survival is of importance because it affects the farmer?s economy and the welfare of the pigs. There are several factors affecting piglet survival and they are often linked to each other. This paper will focus on how the behaviour of the sow can affect the growth and survival of the piglets and also possible causations of differences in maternal behaviour. Sows in intensive production systems have different possibilities to express their maternal behaviour than free ranging sows.

Motivation for eating roughage in sows : as an indiction of hunger

Today?s feeding methods can determine the domestic pig?s abilities to fulfill basic behavioral needs, such as foraging, and the way in which pigs are feed is an important aspect. Feed does not only provide the energy and nutrients critical for survival, but feeding is also associated with a number of other factors contributing to well-being and reproduction. Today the feed for gestated sows is often composed by high energy and low dietary fiber grain products such as wheat. Three kg of this kind of feed can often be consumed by the sow within 20 minutes.

"Osynliga orchidébarn" - Självskadebeteende hos ungdomar sett ur de professionellas perspektiv

The purpose of this study was to examine the professionals´ views concerning self-harm behaviour in adolescents they meet. We interviewed nine different professionals. Our questions were: What do the professionals believe are the reasons to self-harm? How do the professionals experience self esteem and identity in adolescents with self-harm behaviour? How do the professionals look at the self-harm behaviour from a gender perspective? How do the professionals think a diagnosis can affect adolescents with self-harm behaviour? In our responses we noticed beliefs about the cause as a combination of environmental relationships and the individual who is born with a certain vulnerability. The professionals believe that the adolescents have trouble finding their identity.

Ordningsbetyget : för och nackdelar

The main aim of this essay was to find out what kind of advantages and/or disadvantages giving marks in pupils order and behaviour can cause for their development of knowledge and emotional and social skills. We let teachers answer a questionnaire about giving marks in pupils order and behaviour. We have also interviewed one person that was involved to prepare the latest curriculum in 1994, Lpo 94, and they decided that Swedish teachers do not have the right competence to judge ones order or behaviour. We have also looked at different theories about: mark as motivation, mark as information, mark as control, self-fulfilling prophecy, emotional disorders and gender, with whom we analyse the fact to give marks in order and behaviour.What we can establish is that giving marks in pupils order and behaviour seems to bring more disadvantages than advantages. Boys mature later than girls and have there for, in general, not as good behaviour as the girls have in the classroom.

Självskadebeteende hos unga flickor : en studie om sambandet mellan självskadebeteende och kamkamratgrupper och Internet

Self-destructive behaviour is a more and more occurring phenomenon in today?s society and there are mostly young girls who are affected by this behaviour. There are different explanations to why the phenomenon appears. The purpose of this research essay is to give a literature overview of the phenomenon of self-harming behaviour of young girls. Two research questions have been used to study this phenomenon; How can groups of friends contribute to reinforce an identity with the self-destructive behaviour among young girls? How can Internet contributes to reinforce an identity with the self- estructive behaviour among young girls? For the analysis this research essay uses the social constructive theoretical perspective.

Samband mellan tidig ålder vid avskiljning och missriktat diande hos föl :

By tradition horses are weaned at an age of 5-6 months. This study illuminates weaned foals misdirected suckling behaviour, which means that they try to suckle another foal. Since no information about this issue is presented, we decided to perform a behaviour study on weaned foals. The misdirected suckling behaviour was studied on a group with 7 foals, with both fillies and colts. In the group the weaning age varied between 147 days and 215 days, and the first time we observed them, they had been separated from the mares for 12 days.

Automatic registration of dairy cows grazing behaviour on pasture

Information regarding cows grazing behaviour and time spent grazing can be of great interest to dairy farmers, since this information can indicate how well suited the pasture is to the cows. Feed intake at pasture is however challenging to measure. Automated systems for monitoring the behaviour of cows within dairy production have become increasingly important and relatively common. The aim of this study was to validate an activity measuring device (HOBO® G Logger Pendant Data Logger, USA), a triaxial accelerometer that registers the cow?s head positions during grazing, in order to see if cows? grazing behaviour on pasture could be distinguished from their non grazing behaviour.

Arvets betydelse för mjölkkors beteende :

It becomes more important to consider different behaviour traits in the selection for dairy cows to be suitable in the production systems of today. The purpose of this investigation was to study the genetic background to behavioural traits and the heritabilities for temperament, rank order, aggressiveness, feeding behaviour and for learning behaviour. Moreover, the genetic correlations to other traits were studied. To be included in a breeding programme a trait needs to have enough genetic variation, a moderate to high heritability or to be correlated to another measurable trait. Behaviour is a quantitative trait affected by many genes and the environment.
