Variability in disease phenotypes within a single PRNP genotype suggests the existence of multiple natural sheep scarpie strains within Europe [PDF]

open access: yes, 2010
Variability of pathological phenotypes within classical sheep scrapie cases has been reported for some time, but in many instances it has been attributed to differences in the PRNP genotype of the host.

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.

Mineral requirements for growth of wool and hair lambs

open access: yesRevista Brasileira de Zootecnia, 2013
The present study was conducted to determine the body composition and the mineral requirements for growth of wool and hair lambs. A total of 34 castrated lambs with an initial body weight (BW) of 19.9±0.8 kg were used; 17 of these lambs were of the ...

Carcass and meat quality of “Leccese” breed lambs suckling from ewes fed diets containing vegetable by-pass protein

open access: yesItalian Journal of Animal Science, 2011
It is considered necessary to supplement the majority of dietary proteins for the rearing of goats and sheep (Pulina et al., 1990; Robinson, 1987). In ruminants, 70 % of protein requirement is satisfied by cytoplasmic synthesised protein, while the ...

Metazoan-protozoan parasite co-infections and host body weight in St Kilda Soay sheep [PDF]

open access: yes, 2008
For hundreds of years, the unmanaged Soay sheep population on St Kilda has survived despite enduring presumably deleterious co-infections of helminth, protozoan and arthropod parasites and intermittent periods of starvation.

Morphometric analysis of postnatal lung development in the gray short‐tailed opossum (Monodelphis domestica): An ultrastructural study

open access: yesThe Anatomical Record, EarlyView.
Abstract An ultrastructural morphometric analysis of the postnatal development of the lung in the gray short‐tailed opossum (Monodelphis domestica) has been conducted to evaluate the morphofunctional status of this poorly developed marsupial lung immediately following parturition.

The effect of β-carotene supplementation above requirement on the production and reproduction performance of female sheep and goats - A mini review

open access: yesAceh Journal of Animal Science
The high rate of metabolic activity during breeding, pregnancy, parturition and lactation may lead to oxidative stress in sheep and goats. Antioxidant supplementation is proposed as a therapy for encountering resultant stress.

Classification of sheep category using chemical analysis and statistical classification algorithms [PDF]

open access: yes, 2011
In Australia, dentition (eruption of permanent incisors) is used as a proxy for age to define sheep meat quality. Lamb is defined as having no permanent incisors, hogget as having at least one incisor and mutton is defined as having two or more incisors.

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.
