The birth weights of the BS-group calves were lower (P < 0.01) than those of the SS-group calves. During the first two months, the daily weight gain of the SS-group calves was greater (P < 0.05) than that of the BS-group calves. However, between the third and fourth months, the daily weight gain of the BS-group calves was greater (P > 0.05). During the first two months, the chest girth was smaller (P < 0.05) in the BS-group calves than in the SS-group calves, but was similar in both groups by the age of four months. -
Cattle Genetic Resources in Japan: One Successful Crossbreeding Story and Genetic Diversity Erosion

Beef cattle production background I-1. Historical features influencing cattle production Besides pigs and ducks, Sus scrofa and Anas sp., no ancestral domesticated animals naturally inhabited Japan. Domestic animals, such as pigs, cattle and chickens were introduced in the late Jomon (~ B.C. 500) to Yayoi Eras (B.C. 500 – A.D. 300). A Chinese historical book (~ A.D. 250) described that there were no cattle, horses or sheep in Japan. Because no descriptions of pigs and chickens were found in the book, the possibility of their existence could not be denied. Several books written in the mid 7th century referred to cow’s milk. Engishiki (A.D. 927), written in the Heian Era, is a description of the milk product, “So”, surmised as condensed milk for medical purposes. A reference to a presentation of “So” to the government is made in this book. However, this habit was abolished at the beginning of the 12th century. The government banned the slaughtering of animals, cattle, horses, dogs, monkeys and chickens in A.D. 675. Cattle and horse slaughtering were abolished again in A.D. 742. This suggested that the people of this period ate meat. After the prohibitory edict, meat and milk became less common. -
Random Regression Analysis of Calving Interval of Japanese Black Cows
animals Article Random Regression Analysis of Calving Interval of Japanese Black Cows Shinichiro Ogawa * and Masahiro Satoh Graduate School of Agricultural Science, Tohoku University, Sendai 980-8572, Miyagi, Japan; [email protected] * Correspondence: [email protected]; Tel.: +81-22-757-4114 Simple Summary: Genetic parameters for the calving interval of Japanese Black cows were estimated by using a random regression model and a repeatability model. Legendre polynomials based on age at previous calving, ranging from 18 to 120 months, were used as sub-models for random regression analysis. The estimated heritability for the calving interval was low and was similar between the models. The estimated genetic correlation between ages was always higher than >0.8. Spearman’s rank correlation of the estimated breeding values between the two models was ≥0.97 for cows with their own records and ≥0.94 for sires of these cows. Therefore, this study supports the validity of fitting a repeatability model to the records of the calving interval of Japanese Black cows for breeding value evaluation. Our results could contribute to determining strategies for selection and management of Japanese Black cattle. Abstract: We estimated genetic parameters for the calving interval of Japanese Black cows using a random regression model and a repeatability model. We analyzed 92,019 calving interval records of 36,178 cows. Pedigree data covered 390,263 individuals. Age of cow at previous calving for each record ranged from 18 to 120 months. We used up to the second-order Legendre polynomials based on age at previous calving as sub-models for random regression analysis, and assumed a constant error variance across ages. -

WAGYU BREEDERS HANDBOOK an Introduction to Wagyu
2018 WAGYU BREEDERS HANDBOOK An introduction to Wagyu. Pamela Armstrong, LVT Maple Row Stock Farm [email protected] www.Wagyupedia.com FOREWARD Many people consider Wagyu beef to be the most tender and flavorful beef in the World. The cattle used to make this beef are docile with good temperaments, and they are known for their intense intramuscular marbling, high fertility rates and calving ease traits. Why wouldn’t a cattle farmer want to raise Wagyu? The internet is flush with information about Wagyu, some of it is accurate and some of it is misleading. This handbook is designed to help breeders decide whether or not raising this breed is the right choice for them. Peer-reviewed journals and academic textbooks were used to create this handbook, and world-renowned Wagyu experts were consulted. There are good opportunities for producers who are informed, careful and realistic. There are many variances within the Wagyu breeds and bloodlines; as well as differences in short and long-fed animals, and results of feeding protocols. Wagyu are very special animals, they are considered a national treasure in Japan. I hope you enjoy and appreciate them as much as I do.

The Genetic Diversity of Japanese Wagyu Using Molecular Markers
Journal of Animal Breeding and Genomics JABG. 2017 Sep, 1(1): 17-22 https://doi.org/10.12972/jabng.20170002 Review OPEN ACCESS The genetic diversity of Japanese Wagyu using molecular markers Hideyuki MANNEN1* 1Laboratory of Animal Breeding and Genetics, Graduate School of Agricultural Science, Kobe University, Nada, Kobe 657-8501, Japan ABSTRACT We have investigated the genetic diversity and structure using several DNA markers, such as mtDNA, Sry gene in Y chromosome and autosomal SNPs for Japanese Wagyu and native cattle in the North Eastern Asia. Most of Japanese cattle mtDNA belonged to Bos taurus mtDNA haplogroups T1, T2, T3 and T4. All Japanese populations included Asian unique mtDNA haplogroup T4 with high frequencies (0.43 – 0.81). The predominant T4 haplogroup may be a result of founder effect when ancestral cattle were introduced to Japan Islands at the immigration. We found that Mongolian cattle have Bos indicus mtDNA with the genetic frequency of 0.20, but no Bos indicus Y chromosome. No Bos indicus mtDNA in both Japanese and Korean samples suggested that the introgression may be a secondary phenomenon, with the earlier cattle in the region being purely Bos taurus. We analyzed 117 SNPs to assess the genetic diversity, structure and relationships of 16 Eurasian cattle populations. The results could suffi ciently explain the genetic construction of Asian cattle populations. These results reflected to the geographical and historical background in each population. The genetic information would contribute to understanding origin of North Asian native cattle, in addition to the origin of Japanese Wagyu cattle. Keywords: Genetic diversity, mtDNA, molecular markers, origin, Wagyu Introduction The Wagyu generally refers to four Japanese native breeds bred in Japan, but nowadays the famous brand name Wagyu includes not only Japanese native cattle produced in Japan, but also animals or even crossbred Japanese native cattle produced in foreign countries such as Australia or the United States. -
Japanese Beef Cattle - Wa Means Japan[Ese] and Gyu Means Cow
Definition and breed makeup Origins Meat Quality Breed Register and its Structure Wagyu is the name of Japanese beef cattle - wa means Japan[ese] and gyu means cow. There are four(4) types of Wagyu Cattle in Japan; Japanese Black Japanese Brown or Red (also known as Akaushi) Japanese Shorthorn Japanese Poll Japanese Beef cattle Japanese Black Japanese Brown (Wagyu) (Red Wagyu) Native Cattle Japanese Shorthorn Japanese Poll These breed have been established by cross between Japanese native cattle and western breeds. The Japanese Black, called “Wagyu”, is the most popular beef cattle in Japan, and this breed was established by cross between Japanese native cattle and several European breeds, including Brown Swiss, Devon, and Ayrshire Japanese Brown, known as “Red Wagyu”, was established by cross with Korean originated cattle and Simmental breed. We have also Japanese shorthorn and Japanese polled, but the population of these two breeds has recently significantly reduced in recent times • For centuries Buddhism was predominant in Japan and meat consumption was prohibited. The utilization of animal products did not become popular until the Meiji restoration in 1868 In the Meiji era many foreign breeds were introduced to Japan and initially crossbred with the native cattle under the direction of the government. Through this, the gene pool for Japanese breed had diluted but the population had expanded. After the initial frenzy of crossbreeding was over, cattle breeders began to improve and promote their own breeds without further crossbreeding within the prefectures. Meat has been consumed in Japan for only about 140 years. Meat eating has only reached widespread popularity in the last 40 years after the “Law for Improvement and Increased Livestock Production” was enacted in 1950s. -
