13. Estimation of genetic parameters for weight traits and Kleiber Index in a Brahman cattle population
ABSTRACT: Interest in improving feed efficiency of cattle has been increasing. The residual feed intake (RFI), the most commonly used measurement of feed efficiency, is expensive and can only be used in a small number of animals. The Kleiber Index has also been proposed to measure RFI. In this study, we estimated genetic parameters for the Kleiber Index aver

14. Profile of skin diseases in a community of fishermen in the northern coast of the state of São Paulo: the expected and the unusual
Abstract: Background: The fishing colony of the Picinguaba neighborhood is located at the northern end of the coast of the state of São Paulo. It has about 300 residents, of which approximately 100 are professional fishermen. Objectives: This study aimed to identify the main dermatoses of the community in comparison with other populations, and their frequ

15. The urban and rural capybaras (Hydrochoerus hydrochaeris) as reservoir of Salmonella in the western Amazon, Brazil
RESUMO: A capivara (Hydrochoerus hydrochaeris) é o maior roedor do mundo. No estado do Acre, Brasil, as populações de capivaras têm aumentado significativamente. O papel das capivaras na transmissão de certas infecções zoonóticas bacterianas não é bem compreendido, incluindo as bactérias do gênero Salmonella. Salmonella spp. geralmente causam ent

16. Morphological characterization of Amiata donkey through Multivariate analyses
ABSTRACT The objective of this study was to evaluate the morphology and biometrics of female Amiata donkeys reared in four different areas of southern Tuscany, Italy, to determine the differentiation degree of animals. Four southern Tuscan areas were investigated: two mountainous zones (East and West Amiata) and two flatter areas (Coastal area and Siena surr

17. Isolation and characterization of mesenchymal stem/stromal cells from Ctenomys minutus
Abstract Mesenchymal stem/stromal cells (MSCs) are multipotent cells distributed in all tissues and characterized by adherence, morphology, immunophenotype and trilineage differentiation potential. The present study aimed to isolate and characterize adherent MSC-like populations from different tissues of Ctenomys minutus, a threatened wildlife rodent popular

18. A survey of freshwater and terrestrial snails in a predominantly urban municipality of Rio de Janeiro State, Brazil, with emphasis on human parasites vectors
ABSTRACT Many snail species act as intermediate hosts of helminths that transmit diseases to humans and animals, such as schistosomiasis and angiostrongyliasis. São Gonçalo, a mostly urban municipality in Rio de Janeiro State, Brazil, has undergone fundamental environmental impacts, which favor the establishment of a range of diseases, for which snails act

19. Empirical models to predict feed intake of growing-finishing pigs reared under high environmental temperatures
ABSTRACT Several empirical models were proposed to predict feed intake (FI) of growingfinishing pigs reared under high environmental temperatures. However, these models have not been evaluated under conditions different from those in which they were developed. Twelve empirical models were evaluated using a database built after systematic literature review (o

20. Non-neurotoxic activity of Malayan krait (Bungarus candidus) venom from Thailand
Abstract Background: Envenoming by kraits (genus Bungarus) is a medically significant issue in South Asia and Southeast Asia. Malayan krait (Bungarus candidus) venom is known to contain highly potent neurotoxins. In recent years, there have been reports on the non-neurotoxic activities of krait venom that include myotoxicity and nephrotoxicity. However, res

21. HSF1 and HSPA6 as functional candidate genes associated with heat tolerance in Angus cattle
ABSTRACT The purpose of this study was to access and characterize single nucleotide polymorphisms (SNP) located within the HSF1 and HSPA6 candidate genes for adaptability in Angus breed raised in subtropical climate. Samples of DNA from 20 animals representing extreme phenotypes for adaptability traits were obtained. Sequence variations in the candidate gene

22. Factors affecting the performance of Pantaneiro horses
ABSTRACT This study aimed to assess the physical performance of Pantaneiro horses with and without equine infectious anemia (EIA) under functional conditions of cattle management. The horses were subjected to a performance test and split into two groups according to a completely randomized design: animals were chosen from populations testing positive and neg

23. Comparison of Gut Microbial Diversity in Beijing Oil and Arbor Acres Chickens
ABSTRACT The Beijing oil (BJO) chicken is an autochthona Chinese breed which shows outstanding meat quality characteristics compared with fast-growing imported chickens such as Arbor Acres (AA) chickens. Gut microbial diversity has been shown to influence host factors such as energy and nutrient metabolism, immune response and fertility. Consequently, it is

24. Molluscicidal effect of Euphorbia umbellata (Pax) Bruyns latex on Biomphalaria glabrata, Schistosoma mansoni host snail
ABSTRACT Euphorbia umbellata (Pax) Bruyns is an easily cultivated shrub, with occurrence in the tropical regions of the American and African continents. Chemical studies have revealed that the latex of this plant is rich in terpene compounds, which are highly toxic to snails Biomphalaria glabrata (Basommatophora: Planorbidae). The aim of this study was to ev
