Organisms increase in size over time (age) due to excess assimilation over metabolic (respiration) energy demands. Most organisms reach a maximum size with increasing age as gain and loss balance. The von Bertalanffy length-at-age relationship, which is commonly used in fishery assessment...

Objectives: Many UK dogs live into old age, but owners may not recognise or report age-associated signs of disease which lead to negative welfare. This study investigated dog owner and veterinary professional experiences and attitudes towards ageing in dogs, how health care is offered, barriers to...

Objective: To understand the immune status of chicken respiratory mucosa at different stages. Method: The embryo of Hy-line white chickens (18- and 20-day-old), and the nose, larynx, trachea and lung of chickens at different day-age (1-, 4-, 7-, 14-, 21-, 35- and 56-day-old) were selected in this...

This project aims to determine when vets consider a dog to have reached old age and to identify the most common issues discussed in old age dog consultations. There is no agreed consensus on the age at which dogs are considered to be 'old'. Therefore, an alternative approach was used to identify ...

[Objective] To provide reference values of the body weight and urine index in middle and old-aged cynomolgus monkey. [Method] 100 cynomolgus monkey aged from 10-20 years: old (21 were males and 79 were females) were enrolled in die study. We detected the body weight and urine index respectively and ...

Geriatric horses (>15 years) represent a substantial proportion of the equine population. The objective of this study was to (1) report on the cause of death in geriatric horses on a single retirement centre, (2) to evaluate the relationship between PPID status, and mortality rate. Data of 194...

Introduction: Malnutrition in early life affects the growth and development of fetus and children, which has a long-term impact on adult health. Previous studies reveal a relationship between dietary omega-3 polyunsaturated fatty acid (n-3 PUFA) content, brain development, and the prevalence of...

While the lifespan advantage of small body size and mixed breed status has been documented repeatedly, evidence for an effect of genetic diversity across dog breeds is equivocal. We hypothesized that this might be due to a strong right-censoring bias in available breed-specific lifespan estimates...

The experiment was conducted to study the effect of genotype and age on egg quality traits in four different crosses viz. PD1 X PD4 (PA), PD1 X PB2 (PB), PD1X PD3 (PR), PD1X IWI (PW). The egg qualities were measured in 20 eggs each of each cross at 28, 40, 52 and 64 weeks of age. The genotype...

Background and Aim: Sow culling is an important practice in commercial swine production because it is directly associated with the economic efficiency of the breeding herd. This study was conducted to analyze the reasons for sow culling and quantify the factors affecting culling in crossbred...
