"Pit bulls and pit bull-type dogs spark intense controversies, from breed bans to fierce defenses by shelter and rescue organizations and breed advocates. Bad Dog draws from the increasingly ...contentious world of human/dog politics, featuring rich ethnographic research with dogs and their advocates that explores the ways that relationships between humans and animals do not just reflect but actively shape experiences of race, gender, ethnicity, sexuality, nation, breed, and species. Weaver develops the concept of interspecies intersectionalities, bridging discussions in animal studies with feminist, critical race, queer, and trans theories. Contrasting ways of knowing that involve harm reduction-style efforts oriented toward keeping humans and animals together and shelter-based practices of working and playing with dogs, with the white, middle-class "family values" inherent in the work of most animal rescuers, Weaver proposes a reading of
To determine the correlation between the molecular weight (MW) of proteins in seminal plasma and spermatozoa and the quality of fresh and frozen semen production in Pasundan bulls.
Nine selected ...Pasundan bulls, aged 5-10 years, from the Regional Artificial Insemination Center at Ciamis, West Java, Indonesia, were used in the study, with fresh semen sperm motility ≥70% and <70%. We analyzed the motility, viability, integrity of the intact plasma membrane (IPM), and the morphological characteristics of spermatozoa. 1D-SDS-PAGE analysis was performed to determine the protein profile by assessing MW, depicted as bands on the gel.
The motility, viability, and IPM of spermatozoa had lower values (
< 0.05) in Pasundan bulls named Bagaskara and Kertarajasa compared to the other bulls. Proteins with MW 35-50 kDa were not detected in the seminal plasma of Pasundan bulls, exhibiting low quality in fresh semen. The correlation analysis showed that the non-detected proteins with MW 35-50 kDa in seminal plasma correlated with spermatozoa motility (
0.421), viability (
0.424), and IPM (
0.428) so that fresh semen quality was low in both Pasundan bulls. Analysis of semen volume, spermatozoa concentration, and spermatozoa motility showed that the average frozen semen production of Pasundan bulls per ejaculate was 128.73 ± 15.35 straws.
Protein analysis based on MW is a predictive indicator for the quality of fresh semen and the production of frozen semen in Pasundan bulls. Evaluation parameters of fresh semen quality by MW analysis can be used to select Pasundan bulls in Indonesia.
The goal of the paper was to identify b - lactoglobulin gene polymorphism in bulls. The b - lactoglobulin (LGB) is expressed in milk and is important in the evaluation of milk production potential ...and butterfat and protein content. LGB is localized on bovine chromosome 11. The AA genotype of LGB is associated with higher milk yield, the BB genotype with higher fat and casein content and is more desirable for cheese making. The material involved 46 bulls (Slovak spotted breed – 41 bulls, Pinzgau breed – 3 bulls and Holstein breed – 2 bulls). Bovine genomic DNA was isolated from sperm using commercial kit NucleoSpin Tissue and used in order to estimate LGB genotypes by means of PCR RFLP method and high resolution melting analysis (HRMA). In the population of Slovak spotted breed we detected all genotypes AA, AB and BB with frequency 0.3415, 0.4390 and 0.2195, subsequently. In Pinzgau breed was detected homozygote genotypes AA and BB with frequency 0.3333 and 0.6667. In Holstein breed was observed only heterozygote genotype AB with frequency 1.

The objective of this study is to determine the effect of species, season, and their interaction on laminitis prevalence in three semen-donor bull species in the Artificial Insemination Centre under ...tropical conditions. The average prevalence in each species (Bos taurus, Bos indicus, and Bos sondaicus) was calculated based on the number of monthly incidents compared to the current population during 2020, while the two-way ANOVA was used to determine the effect of species, seasons (wet and dry season) and species-season interactions to the prevalence of laminitis. The average prevalence in Bos taurus, indicus, and sondaicus during dry season was 7.582±1.841%, 1.190±1.844%, 0.451±1.103%, and during wet season was 8.521±4.808%, 1.262±1.960%, 0.451±1.103% respectively. This study revealed that Bos taurus bull species more susceptible to laminitis compared to Bos indicus and Bos sondaicus. However, there is no influence of seasons and interactions between seasons and species on laminitis prevalence. In conclusion, this study has proven that laminitis can occur in all semen-donor bull species despite differences in susceptibility, species, or season.
•Non-additive genetic effect could impact on semen production traits.•Genome-wide association studies were performed in beef and dairy bulls.•The significant non-additive quantitative trait loci were ...detected in each breed.•The highest non-additive effect on chromosome 17 was detected in dairy bulls.•Effective genetic selection can be achieved by removing risk alleles.
Semen production traits are important aspects of bull fertility, because semen quantity leads to direct profits for artificial insemination centres, and semen quality is associated with the probability of achieving a pregnancy. Most genome-wide association studies (GWASs) for semen production traits have assumed that each quantitative trait locus (QTL) has an additive effect. However, GWASs that account for non-additive effects are also important in fitness traits, such as bull fertility. Here, we performed a GWAS using models that accounted for additive and non-additive effects to evaluate the importance of non-additive effects on five semen production traits in beef and dairy bulls. A total of 65 463 records for 615 Japanese Black bulls (JB) and 50 734 records for 873 Holstein bulls (HOL), which were previously genotyped using the Illumina BovineSNP50 BeadChip, were used to estimate genetic parameters and perform GWAS. The heritability estimates were low (ranged from 0.11 to 0.23), and the repeatability estimates were low to moderate (ranged from 0.28 to 0.45) in both breeds. The estimated repeatability was approximately twice as high as the estimated heritability for all traits. In this study, only one significant region with an additive effect was detected in each breed, but multiple significant regions with non-additive effects were detected for each breed. In particular, the region at approximately 64 Mbp on Bos taurus autosome 17 had the highest significant non-additive effect on four semen production traits in HOL. The rs41843851 single nucleotide polymorphism (SNP) in the region had a much lower P-value for the non-additive effect (P-value = 1.1 × 10−31) than for the additive effect (P-value = 1.1 × 10−8) in sperm motility. The AA and AB genotypes on the SNP had a higher phenotype than the BB genotype in HOL, and there was no bull with the BB genotype in JB. Our results showed that non-additive QTLs affect semen production traits, and a novel QTL accounting for non-additive effects could be detected by GWAS. This study provides new insights into non-additive QTLs that affect fitness traits, such as semen production traits in beef and dairy bulls.

Summer pruning of fruit species as an alternative for feeding with vegetable waste in beef cattle breeding is observed. The experiment was conducted in 2020 in an experimental farm for beef cows ...(Hornless Hereford breed) of the Research Institute of Mountain Stockbreeding and Agriculture, Troyan (Bulgaria). The animals were fed in a controlled manner with standardized amounts of foliar fodder, obtained after summer pruning of fruit crops (plums, apples, pears). The main purpose of the study is to consider the potential and opportunity of using plant matter after summer pruning (green pruning) in various orchards, as a food reserve in beef cattle breeding. The highest appetite was shown by the leaves and twigs obtained during plum pruning (combined group of two cultivars) (46.6%), followed by those of the apple (31.2%) and the lowest value was registered for pear species (22.2%). The total amount of the three types of fodder is accepted as 100%. Compared to the other studied species, the foliar fodder from Prunus domestica had the highest content of crude protein (20.3%), minerals (11.7%), calcium (2.2%), phosphorus (0.6%) and nitrogen (3.2%).

Printing thrived after it came to Rome in the 1460s. Renaissance scholars, poets, and pilgrims in the Eternal City formed a ready market for mass-produced books. But Rome was also a capital city—seat ...of the Renaissance papacy, home to its bureaucracy, and a hub of international diplomacy—and print played a role in these circles, too. In Papal Bull, Margaret Meserve uncovers a critical new dimension of the history of early Italian printing by revealing how the Renaissance popes wielded print as a political tool.
Over half a century of war and controversy—from approximately 1470 to 1520—the papacy and its agents deployed printed texts to potent effect, excommunicating enemies, pursuing diplomatic alliances, condemning heretics, publishing indulgences, promoting new traditions, and luring pilgrims and their money to the papal city. Early modern historians have long stressed the innovative press campaigns of the Protestant Reformers, but Meserve shows that the popes were even earlier adopters of the new technology, deploying mass communication many decades before Luther. The papacy astutely exploited the new medium to broadcast ancient claims to authority and underscore the centrality of Rome to Catholic Christendom.
Drawing on a vast archive, Papal Bull reveals how the Renaissance popes used print to project an authoritarian vision of their institution and their capital city, even as critics launched blistering attacks in print that foreshadowed the media wars of the coming Reformation. Papal publishing campaigns tested longstanding principles of canon law promulgation, developed new visual and graphic vocabularies, and prompted some of Europe's first printed pamphlet wars. An exciting interdisciplinary study based on new literary, historical, and bibliographical evidence, this book will appeal to students and scholars of the Italian Renaissance, the Reformation, and the history of the book.
