Methods for parentage control in cattle have changed since their initial implementation in the late 1950’s from blood group typing to more current single nucleotide polymorphism determination. In the early 1990’s, 12 microsatellites were selected by the International Society for Animal Genetics based on their informativeness and robustness in a variety of different cattle breeds.

The Nordic Red Cattle consisting of three different populations from Finland, Sweden and Denmark are under a joint breeding value estimation system. The long history of recording of production and health traits offers a great opportunity to study production traits and identify causal variants behind them.

Levels of inbreeding in cattle populations have increased in the past due to the use of a limited number of bulls for artificial insemination. High levels of inbreeding lead to reduced genetic diversity and inbreeding depression. Various estimators based on different sources, e.g., pedigree or genomic data, have been used to estimate inbreeding coefficients in cattle populations.

Infrared spectral analysis of milk is cheap, fast, and accurate. Infrared light interacts with chemical bonds present inside the milk, which means that Fourier transform infrared milk spectra are a reflection of the chemical composition of milk. Heritability of Fourier transform infrared milk spectra has been analysed previously.

Umami is a Japanese term for the fifth basic taste and is an important sensory property of beef palatability. Inosine 5′-monophosphate (IMP) contributes to umami taste in beef. Thus, the overall change in concentration of IMP and its degradation products can potentially affect the beef palatability. In this study, we investigated the genetic architecture of IMP and its degradation products in Japanese Black beef. First, we performed genome-wide association study (GWAS), candidate gene analysis, and functional analysis to detect the causal variants that affect IMP, inosine, and hypoxanthine.

The role of transcription and growth factors in bovine myogenesis is well-characterized; however, very little is known about the miRNA activity during this process. We have hypothesized that the expression of miRNA can vary between primary cultures of skeletal muscle cells isolated from the semitendinosus muscles of different cattle breeds and subjected to myogenic differentiation.

Korean Hanwoo cattle are known for their high meat quality, especially their high intramuscular fat compared to most other cattle breeds. Different muscles have very different meat quality traits and a study of the myogenic process in satellite cells can help us better understand the genes and pathways that regulate this process and how muscles differentiate.

The cattle introduced by European conquerors during the Brazilian colonization period were exposed to a process of natural selection in different types of biomes throughout the country, leading to the development of locally adapted cattle breeds.

The study also relies on secondary sources including a wider range of literature given at various levels for its completeness and comprehensiveness. The study revealed different characteristics, management practices and conservation strategies adopted for the Bargur breed. The study helps to understand the role of the breed in eco system stability and thus the importance of the breed conservation.

The major thrust in dairy cattle breeding programme has been to identify potential parents with high breeding value for next generation. In general, two breeding strategies are available for improvement of cattle, i.e. selective breeding with in a breed and cross breeding among breeds (Falconer and Mackay, 1996). For the formulation of effective genetic improvement programme, basic knowledge of genetic parameters of a herd must be known with maximum accuracy.

The aim of this study was to determine prevalence of Leptospira interrogans serovar hardjo in the define area. To serve the purpose a total 398 serum samples were collected from different age group, breed and sex of cattle. Out of 398, some of cattle (101) showed history of abortion, mastitis/agalactia/oligolactia, repeat breeder and fever.

The effectiveness of progesterone sponges to treat the anestrus animals and to synchronisation was reported in several previous study using different breeds of cattle and buffalo. The present study was carried out to assess estrus induction potential and conception rate in indigenous Kangayam cows inserted with progesterone impregnated intravaginal sponge.

Salmonella is an enterobacterium present in the environment as well as in a large number of animals which, in most cases, serve as host asymptomatically. This bacterium is the leading cause of collective food poisoning in the world. In view of the expansion of salmonellosis in the world and the emergence of multi-resistant strains of Salmonella, this is a threat to human safety. The aim of this study is to determine the prevalence rate of Salmonella and their antibiotic resistance profile, antibiotics often used in cattle breeding in the district of Abidjan.

The study aimed to evaluate oxidative stress status in cattle breeds of different thermotolerance during different seasons. Ten each of Tharparkar (Bos indicus) and Karan Fries (Bos indicus x Bos taurus) heifers were selected from NDRI herd, Karnal. Animals were maintained under standard managemental practices followed at the farm. Blood samples were aseptically collected from each animal during winter, spring and summer.

The study was conducted on male (1 wk to 12 m age) and female (1 wk to 36 m age) Gir cattle and Jaffarabadi buffaloes maintained on an organised farm. Age exerted significant (P < 0.05) effect on AST, ALT and LDH activity in both the sexes of Gir and Jaffarabadi breed. AST values in adult Gir females at 24 and 36 m age were lesser than the values observed at 1 wk of age. The increase in AST as age increased was noted in Gir males. The effect of age on AST levels in Jaffarabadi females and males was found to be significant (P < 0.

India, third richest biodiversity countries in the Asia, and it is home to huge indigenous cattle genetic resources. India having 190.9 million cattle population with 43 register native indigenous cattle breeds, in addition to this large number of non-descript cattle population available throughout country. This indigenous cattle breeds are especially more adapted to different agro-climatic conditions of India and some of indigenous cattle breeds were performing excellent in other country throughout world.

The present research trial was carried out in kharif and summer season from year 2013-2015 at Cattle Breeding Farm, Junagadh agricultural University, Junagadh, Gujarat. Gundrijowar fodder samples were collected for quantitative HCN (mg/100 gm dry matter) concentration from eight sown plots from 15 DAS (Day after sowing) up to 60 DAS at fortnightly intervals and one more sampling was carried out when Gundrijowar fodder crops exhibit 25% flowering stage.

Anaplasma is one of the most rickettsiale diseases in ruminants. Five species including Anaplasma marginale, Anaplasma centrale, Anaplasma bovis, Anaplasma phagocytophilium and Anaplasma ovis are recognized in ruminant animals. Anaplasma causes major economic losses to the livestock owner. Anaplasma is mainly transmitted by mechanical way such as by biting flies, lice and biological by different tick species and fomites in livestock.
