1. Challenges to increase the AI and ET markets in Brazil
Abstract Artificial insemination (AI) and embryo transfer (ET) are the most widely used biotechnologies in the world with the goal of increasing genetic gain and improving reproductive efficiency of beef and dairy herds. The protocols for ovulation synchronization for timed AI (TAI) or ET (TET) are tools that allow artificial insemination or transfer of a hi

2. Neuroaxonal Dystrophy in a mule: first case reported
RESUMO Relata-se o caso de uma mula de 12 meses que apresentou alterações neurológicas inespecíficas (ataxia simétrica, dismetria, déficit proprioceptivo consciente e fraqueza). Devido ao mau prognóstico e ao fato de um irmão da geração anterior apresentar sinais clínicos similares sem diagnóstico conclusivo, o animal foi eutanasiado. O diagnóst

3. Overprice on purchase of replacement cattle and genetic group as variables of economic result in feedlot operations
ABSTRACT The objective of this study was to analyze the economic result of feedlot operation for three genetic groups of cattle (Nellore, Nellore crossing with other Zebuine breeds, and Dairy crossbred) as a function of the overprice on the purchase price of cattle to be feedlot-finished. The study involved data of 57,589 animals divided into 709 lots origin

4. Crossbreeding locally adapted hair sheep to improve productivity and meat quality
ABSTRACT: The use of lambs from crossing of local with specialized sheep breeds for meat production may lead to higher meat deposition and a smaller fat amount in the carcass, with a more adequate nutritional profile for human consumption. This study investigated the performance, carcass and meat characteristics of lambs from the Morada Nova and Santa Inês

5. Linkage disequilibrium levels and allele frequency distribution in Blanco Orejinegro and Romosinuano Creole cattle using medium density SNP chip data
Abstract The linkage disequilibrium (LD) between molecular markers affects the accuracy of genome-wide association studies and genomic selection application. High-density genotyping platforms allow identifying the genotype of thousands of single nucleotide polymorphisms (SNPs) distributed throughout the animal genomes, which increases the resolution of LD ev

6. Transplantation of human immature dental pulp stem cell in dogs with chronic spinal cord injury
Abstract Purpose: To investigate the therapeutic potential of human immature dental pulp stem cells in the treatment of chronic spinal cord injury in dogs. Methods: Three dogs of different breeds with chronic SCI were presented as animal clinical cases. Human immature dental pulp stem cells were injected at three points into the spinal cord, and the animal

7. Coprophilous Mucorales (ex Zygomycota) from three areas in the semi-arid of Pernambuco, Brazil
Abstract Mucorales comprises fungi commonly isolated as saprobes from soil, dung, stored grains and plants. Although these fungi have been studied in several countries, there are relatively a few reports of them in semi-arid areas. Therefore, the aims of the present study were to assess and compare the Mucorales communities in dung from different species and

8. Morphometric measurements and animal-performance indices in a study of racial forms of Brazilian Sport Horses undergoing training for eventing
ABSTRACT This study aimed to evaluate, in a practical manner, the use of linear and angular measurements and different animal-performance indices in a study on the breed-specific conformation of Brazilian Sport Horses training for eventing. These data can form the basis for the development of future studies based on the parameters evaluated and the calculati

9. Genetic and environmental variance and covariance parameters for some reproductive traits of Holstein and Jersey cattle in Antioquia (Colombia)
The objective of this study was to estimate the genetic, phenotypic and environmental parameters for calving interval (CI), days open (DO), number of services per conception (NSC) and conception rate (CR) in Holstein and Jersey cattle in Antioquia (Colombia). Variance and covariance component estimates were obtained by an animal model that was solved using t

10. Models for estimating feed intake in small ruminants
This review deals with the most relevant limits and developments of the modeling of intake of sheep and goats reared intensively and extensively. Because small ruminants are normally fed ad libitum, voluntary feed intake is crucial in feeding tactics and strategies aimed at optimal animal production. The effects of genetic, neuroendocrine, hormonal, feed and

11. Investigação soroepidemiológica e molecular de brucelose e leptospirose em núcleos de conservação de gado curraleiro pé duro e pantaneiro / Seroepidemiological and molecular monitoring of brucellosis and leptospirosis in nucleus of in situ conservation of curraleiro pé-duro and pantaneiro breeds
As raças bovinas localmente adaptadas aos diferentes ecossistemas brasileiros caracterizam-se como uma alternativa para produção de alimentos, por apresentarem entre outras características, maior resistência a enfermidades. O objetivo geral foi avaliar a situação epidemiológica da brucelose e da leptospirose em núcleos de conservação de bovinos Cu

12. Prospecção de SNPs por eletroforese capilar e sua identificação em genes candidatos relacionados à resistência de caprinos a nematóides gastrintestinais / Prospection of SNP by capillary electrophoresis related to resistance to gastrointestinal infection by nematodes in goats
The cytokines are small cell-signaling proteins that play important role in immunologic system acting in intracellular communication. Five genes from cytokine family, i.e., IL2, IL4, IL13, IFNg, and TNFa were selected to search for SNPs, which may be associated with goat gastrointestinal endoparasites resistance. A population of 229 goats was produced in Emb
