Comparing SNP Panels and Statistical Methods for Estimating Genomic Breed Composition of Individual Animals in Ten Cattle Breeds
He et al. BMC Genetics (2018) 19:56 https://doi.org/10.1186/s12863-018-0654-3 RESEARCH ARTICLE Open Access Comparing SNP panels and statistical methods for estimating genomic breed composition of individual animals in ten cattle breeds Jun He1,2†,YageGuo1,3†, Jiaqi Xu1,4, Hao Li1,5,AnnaFuller1, Richard G. Tait Jr1,Xiao-LinWu1,5* and Stewart Bauck1 Abstract Background: SNPs are informative to estimate genomic breed composition (GBC) of individual animals, but selected SNPs for this purpose were not made available in the commercial bovine SNP chips prior to the present study. The primary objective of the present study was to select five common SNP panels for estimating GBC of individual animals initially involving 10 cattle breeds (two dairy breeds and eight beef breeds). The performance of the five common SNP panels was evaluated based on admixture model and linear regression model, respectively. Finally, the downstream implication of GBC on genomic prediction accuracies was investigated and discussed in a Santa Gertrudis cattle population. Results: There were 15,708 common SNPs across five currently-available commercial bovine SNP chips. From this set, four subsets (1,000, 3,000, 5,000, and 10,000 SNPs) were selected by maximizing average Euclidean distance (AED) of SNP allelic frequencies among the ten cattle breeds. For 198 animals presented as Akaushi, estimated GBC of the Akaushi breed (GBCA) based on the admixture model agreed very well among the five SNP panels, identifying 166 animals with GBCA = 1. Using the same SNP panels, the linear regression approach reported fewer animals with GBCA = 1. -

II. Outbreeding and Hybrid Vigour
II. Outbreeding and Hybrid vigour II. Outbreeding and Hybrid vigour • Outbreeding is the opposite of inbreeding, it is the mating of animals less closely related than the average relationship within the breed. • If two individuals do not have any ancestors in common for five or six generations back in their respective pedigrees, they are usually thought not being any more related than the average of the population Consequences of outbreeding 1. Outbreeding increases the number of pairs of heterozygous genes in the individual 2. Outbreeding tends to decrease breeding purity 3. Outbreeding tends to cover up detrimental recessive genes. 4. Phenotypically, outbreeding usually improves traits related to physical fitness (hybrid vigour). Hybrid vigour or heterosis • Heterosis, or hybrid vigour, is the name given to the increased vigour of the offspring over that of the parents when unrelated individuals are mated. • In 1914 Professor Shull proposed for the first time the word “heterosis ” • The best known example for hybrid vigour in animals is the mule (male ass and mare) • The reciprocal cross, called the hinney or jennet Types of heterosis • There are three main types of heterosis (Individual, Maternal, Paternal) 1) Individual (direct) heterosis • It is the improvement in the performance of crossbred individual above the average of its parents. • It is affected by Individual’s gene that directly affects on its performance. • All traits have what is called a direct or individual component of heterosis • Examples (weaning weight, yearling weight and carcass traits) 2- Maternal Heterosis • It is the improvement in the performance of the crossbred mother over the average of purebred mothers Example: I. -

Data Makes the Difference
Data Makes the Difference By Lisa Bard, Santa Gertrudis USA Editor The genetic advancements made in the Santa Gertrudis breed in the past 10-15 years are apparent now more than ever. At a time when some other breeds struggle, demand for Data Driven – Profit Proven Santa Gertrudis bulls and females is strong and remains so, even when the cattle cycle began its downward trend following the highs a few years ago. Santa Gertrudis has proven to be a breed whose performance is backed by data – and that is what has made the difference. At the recent 2020 International Super Sale, held March 6 during the Houston Livestock Stock Show and Rodeo, Leachman Cattle of Colorado (LCoC) bought the pick of the Schuster Farms ET calf crop and then, in partnership with Shuster Farms, bought the pick of embryo transfer (ET) calves from Quail Valley Farms. For one of the leading seedstock bull producers in the nation to invest in Santa Gertrudis genetics is no minor thing. Annually, LCoC markets more than 2,000 bulls, including Angus, Red Angus, Stabilizer composites (with both black and red lines) and Charolais. Approximately 2.5 years ago, they started to incorporate Brangus into the black Stabilizer line and have been looking for ways to add Bos indicus genetics to the red Stabilizer line. Lee Leachman, LCoC CEO, acknowledges that they have been investigating ways to incorporate Santa Gertrudis into their breeding program for quite some time. This year, with confidence that the breed and breeders are moving forward, the tipping point came. Leachman was very encouraged by a group of cattle in the International Super Sale offering that were substantially better than the mean in terms of their expected progeny differences (EPDs) – and they decided to jump in. -
Why Texas Longhorn Cattle? by Russell Hooks
Why Texas Longhorn Cattle? By Russell Hooks In my thirty five plus years of breeding, preserving and promoting Texas Longhorn cattle I have been ask numerous questions about the breed. However I would have to say the most often asked question is “why do y ou raise Longhorns”. This question is not a simple single answer but rather a question with multiple answers which I am going to share with you in this article. First off, they are one of the easiest breeds of cattle to raise and do not require a lot of cattle knowledge or experience working with cattle. One of the factors that make Longhorns a “no hassle” breed is their natural resistance to numerous diseases and parasites. Longhorns seem to have a natural immunity developed over centuries of having to make it on their own with little too no help from mankind. This translates into fewer veterinarian bills and less maintenance cost for an individual choosing to raise Texas Longhorns. Another reason as to “why Longhorns” is their browse utilization. Longhorn cattle will take advantage of whatever type of forage is available thus requiring less supplemental feed to maintain an adequate body condition. Most Longhorn cows weight less than1200lbs which means less cost to maintain the cows. They also put less stress on your pastures by their lower forage requirements and by their willingness to consume different types of vegetation. This allows the rancher to possibly increase his carrying capacity, which increases the number calves produced thus increasing the potential profits. Adaptability is another good reason for raising Longhorn cattle.
