Lamb wastage and its association with ewe body condition
The effect of ewe body condition and live weight, and change in these factors, on lamb wastage was examined in a composite (principally Coopworth) flock of small- or large-framed ewes. Approximately equal sized flocks of small- and large-framed ewes, balanced for age and condition were selected …

Relationships of Body Condition, Blood Glucose and Insulin Concentration of Grazing Horses
… (Pass et al., 1998). Other studies have reported body fat and insulin resistance are also positively correlated in horses and humans (Hoffman et al., 2003; Boshell et al., 1968; DeFonzo et al, 1991; Kahn et al., 2000). Few studies have monitored these relationships in horses consuming forage only …

Reproduction, Body Condition and Dietary Variation of the Lesser Siren (Siren Intermedia)
… size was positively correlated with female body size (SVL). I estimated the body condition of adult male sirens using a mass/length regression analysis and found that breeding males were in poorer body condition than nonbreeding males. Dietary analysis showed that sirens are generalists …

Influence of seasonal drought on body condition and nutritional state in selected tropical birds
… intensity on indicators of individual-level condition and nutrition across a suite of understory species. Changes in food-resource availability during seasonal drought is one possible mechanism driving the population level responses to dry season length in tropical birds. This project …

Changes in Body Condition from Prepartum to Postpartum on Health and Reproduction in Dairy Cattle
The aim of this study were to body condition score, 72 Holstein-Friesian dairy cows at prepartum, compare lean, moderate, and over-conditioned categories, and relate any changes associated with the various time points with reproductive success by measuring body condition score, hematocrit, total …

Effects of Training and Experience on Repeatable and Reliable Assessment of Beef Cattle Body Condition Scores
In recent years, body condition scores (BCS) have been included in Expected Progeny differences (EPD) calculations for maintenance energy. This experiment was designed to identify the acuteness at which technicians of different skill levels can correctly quantify BCS in beef cattle. Thirteen …

Indirect effects of agricultural intensification on tree swallow (Tachycineta bicolor) foraging behaviour, body condition, and physiology
… (i) foraging behaviours and return rates, (ii) body condition, and (iii) selected physiological responses (i.e. oxidative stress and feather corticosterone). Artificial nest-boxes were erected at each of 5 sites with varying levels of agricultural intensification in south-central Saskatchewan, …

Artificial Night Lighting and Anthropogenic Noise Alter Animal Activity, Body Condition, Species Richness, and Community Structure
… of kilometers from the source. Despite a large body of work investigating the effects of light or noise pollution acting alone, relatively few studies have examined the effects of both stimuli acting together even though they frequently co-occur. Better understanding how these stressors, …

The effects of a dairy cow body condition scoring system on selected production and metabolic parameters
A dairy cow body condition scoring system was devised by the author as a practical means of determining the body condition, or fitness pertaining to the degree of body fat of dairy cows at any point during the lactation cycle. The factors considered were the thoracic and lumbar regions of the …

Comparing body condition and foraging ecology of two populations of Cape Gannets on Bird and Malgas Islands
… mass. I compared the foraging ecology, diet and body condition of adult Cape gannets from two colonies, one where individuals have been feeding on fishery wastes (hake) for several years (Malgas Island; west coast) and the other where individuals feed on natural prey (Bird Island; south coast). …

Effect of body condition and ration protein source on performance of high producing cows during early lactation
… high producing Holstein cows were paired by body condition and mature equivalent milk production and fed either a high or low energy complete ration ad libitum during the last 16-20 weeks of lactation. Cows fed the high energy ration ate more feed, produced more milk and gained more body …

Subdermal Fat Determined by Ultrasound and Electrical Conductivity, and Its Relationship to Body Condition Score of Dairy Cows
Body condition score (BCS), a very useful field tool for estimation of changes in body tissue reserves is time consuming and subjective. The relationship between body condition score and subdermal fat (SFAT) was determined biweekly as potential for development of a low cost, portable digital …

Effects of nutrition, disease, and body condition score during the transition period on dairy cattle liver gene expression
… in nutrition, metabolism, and inflammatory conditions through different mechanisms. This study will help to clarify the role of FGF21 as a nutrition adaptation factor in dairy cows (For details see chapter 2). The liver has a precise role in lipid metabolism; any change in dietary lipid …

The influence of vulture restaurants on breeding success and nestling body condition of Gyps vulture populations across southern Africa
… Here, I assessed the relationship between chick condition (African White-backed Vultures) and breeding success (Cape Vultures/African White-backed Vultures) in relation to a variety of variables which described levels of access to vulture restaurants. My data suggest the potential of vulture …

Influence of body condition and homo- vs. heterosubtypic immunity on influenza A virus infection in mallard ducks : experimental infection data
… the natural variation in physiological condition observed in migrating waterfowl and have only used captive-bred birds. We assessed how body condition affects susceptibility, viral shedding, and antibody production in wild-caught and captive-bred juvenile mallards challenged with IAV …

Group Differences in Mother-Infant <i>Macaca fascicularis</i> Behavior, Parasite Load, and Body Condition within an Anthropogenically Altered Forest
… there was parasitic variation between groups. Body condition scores were determined using a newly created and adapted body condition scale from 146 sampled mother macaques. Body condition scores were significantly different between groups, specifically the pond group when compared to the three …

Establishing a weight-length baseline for evaluating changes in yellowfin tuna (Thunnus albacores) body condition in the Western Indian Ocean
… environmental variability and yellowfin tuna condition were observed. Concentrations of suitable prey in 2003 and 2004 correlated to above average condition, although 2005 and 2006 were below average condition during similar prey availability and environmental conditions. Relative weight …
