Welcome to our 115th Angus Production Sale. We confidently present our highest quality and most uniform offering of seedstock to date. Striving toward continual genetic improvement is a motivating and exciting challenge. The greatest reward we can receive is the satisfaction of knowing the SAV brand is positively impacting the programs and livelihoods of our customer base and benefiting the beef industry.
We are very grateful and humbled for your support that has made the SAV brand flourish and become a dominant presence in the beef industry and the most recognized and respected brand of Angus genetics around the world. We fully understand the responsibility and expectations that come with this honor and are committed to producing the kind of genetics that will enhance real-world productivity and profitability. The barometer on which we gauge our breeding program is disciplined and focused on the essentials that affect profitability of the cowman who sells pounds for a living, with the necessity to do it in an efficient and practical manner. A keen awareness of performance, phenotype, structure and maternal traits remain paramount, with particular emphasis on the cowherd and basic
profit-driving traits beyond EPDs or computer projections – fertility, fleshing-ability, structural integrity, maternal quality and the bred-in ability to raise heavy, market-topping calves and produce a quality end product. We are pleased to see that many of the top-selling feeder cattle and replacement heifers in the country are influenced by SAV genetics and gratified to see harvest data from many large and diverse commercial herds showing that SAV genetics are earning the highest end-product premiums being paid today. This real-world information and customer feedback give us the insight to advance and refine our program.
Our innovative breeding program is constantly calibrated to monitor improvements and advancements in the genetic product we offer. As you turn the pages of this catalog, you will see the results of these efforts. The offering is loaded with performance and quality and the selection is vast – presenting an opportunity to access reputation SAV genetics in volume with an excellent selection in price ranges affordable to the cowman. The 2018 bull offering the highest performing set we
have ever offered. It has been a highlight of my year watching this competitive set of bulls grow and advance toward sale day. They are truly the kind we strive to produce. The female offering includes hand-picked bred heifer, cow and donor features, and a sensational set of replacement females representing the freshest genetics of our program and daughters from all of our leading donors and cow families. These females all carry the authentic SAV prefix that is recognized all around the globe. You are truly investing in a piece of the program – they will make a lasting contribution and have a lifetime of earning potential.
The success of our customers is our greatest inspiration and our highest priority. It is an honor and privilege to serve as your seedstock source and we thank you for the confidence you have placed in our program. If we can be of any assistance in any way, please don’t hesitate to contact us. We look forward to seeing you on sale day!
Sincerely,
Kelly Schaff
O Departamento de Reprodução Animal da Faculdade de Medicina Veterinária e Zootecnia da Universidade de São Paulo (FMVZ/USP) elabora, desde 2002, estudo para avaliar o desempenho do mercado de protocolos de sincronização para o emprego da Inseminação Artificial em Tempo Fixo (IATF) em bovinos. Esses dados são comparados com as informações divulgadas pela ASBIA (Associação Brasileira de Inseminação Artificial), quanto ao número de doses de sêmen comercializadas (INDEX ASBIA-CEPEA), buscando estimar a evolução da comercialização de protocolos para realização da IATF, associada ao mercado de venda de sêmen no Brasil.
BARUSELLI, P.S. Em 2023, apesar da redução do número de protocolos comercializados, 91,2% das inseminações no Brasil foram realizadas por IATF Boletim Eletrônico do Departamento de Reprodução Animal/FMVZ/USP, 8a ed., 2024.
O INDEX ASBIA 2023 já está disponível para download.
As principais informações sobre o mercado de genética bovina e inseminação artificial no ano passado são expostas em detalhes no INDEX.

Genomic loci involved in sensing environmental cues and metabolism affect seasonal coat shedding in Bos taurus and Bos indicus cattle

Seasonal shedding of winter hair at the start of summer is well studied in wild and domesticated populations. However, the genetic influences on this trait and their interactions are poorly understood. We use data from 13,364 cattle with 36,899 repeated phenotypes to investigate the relationship between hair shedding and environmental variables, single nucleotide polymorphisms, and their interactions to understand quantitative differences in seasonal shedding. Using deregressed estimated breeding values from a repeated records model in a genome-wide association analysis (GWAA) and meta-analysis of year-specific GWAA gave remarkably similar results. These GWAA identified hundreds of variants associated with seasonal hair shedding. There were especially strong associations between chromosomes 5 and 23. Genotype-by-environment interaction GWAA identified 1,040 day length-by-genotype interaction associations and 17 apparent temperature-by-genotype interaction associations with hair shedding, highlighting the importance of day length on hair shedding. Accurate genomic predictions of hair shedding were created for the entire dataset, Angus, Hereford, Brangus, and multibreed datasets. Loci related to metabolism and light-sensing have a large influence on seasonal hair shedding. This is one of the largest genetic analyses of a phenological trait and provides insight into both agriculture production and basic science.
