S ri Lanka having an a g r i c u l t u r e b a s e d civilisation with an agricultural history of over 13,000 years, the archaeological evidence to confirm the ex is tence of a nomadic era is very scanty or nil. There are still doubts about the indigenous cattle in Sri Lanka, as to whether they are truly indigenous or have been introduced during sometime in the history from our neighbouring cou...

The current review focuses on characterization and conservation efforts vital for the development of breeding programmes for indigenous beef cattle genetic resources in Southern Africa. Indigenous African cattle breeds were identified and characterized using information from refereed journals, conference papers and research reports. Results of this current review reviewed that smallholder beef ...

Information about genetic diversity and population structure among cattle breeds is essential for genetic improvement, understanding of environmental adaptation as well as utilization and conservation of cattle breeds. This study investigated genetic diversity and the population structure among six cattle breeds in South African (SA) including Afrikaner (n = 44), Nguni (n = 54), Drakensberger (...

  reducing production and death. The disease in endemic areas would be mild or subclinical in indigenous cattle and clinically acute in exotics. OBJECTIVES: This study was conducted to evaluate the resistance of indigenous cattle in comparison with Holstein and crossbred cattle against Theileria annulata through assessment of clinical signs and response to treatment. METHODS: For this purpose...

the experiment was conducted to study the effect of treatment of rice straw with urea and a urease containing midden soil on the chemical composition of treated rice straw, feed intake of the animals, nutrients digestibility, body weight gain, feed conversion efficiency and overall economy of feeding for a period of 105 days. twelve indigenous growing cattle (live weight 130.00±1.67 kg) were se...

the objective of the present study was to determine polymorphism within the promoter region of somatotropin receptor genes in indigenous sistani cattle (bos indicus) and associations between this polymorphism and breeding value of birth weight. the pedigree structure was included by considering 1173 animals with 600 progeny birth weight data obtained from a zhark breeding station in sistan and ...

At least 150 indigenous African cattle breeds have been named, but the majority of African cattle populations remain largely uncharacterized. As cattle breeds and populations in Africa adapted to various local environmental conditions, they acquired unique features. We know now that the history of African cattle was particularly complex and while several of its episodes remain debated, there is...

Two experiments were conducted to determine the urinary purine derivative (PD) excretion rates and to analyze potential variations in PD excretions between yak, Tibetan indigenous cattle, and their crossbreds under similar ecological environment, and to develop prediction equations based on PD excretion for estimating rumen microbial protein supply. Three Tibetan castrated male yaks, and simila...

csn1s1is one of the major genes encoding milk proteins of mammals. in this study we determined allele frequencies of csn1s1-5` flanking region as well as exon 17 variants and their effects on milk traits in three indigenous cattle breeds mazandarani, golpaygani (bos indicus) and sarabi (bos taurus) and holstein cattle in iran. csn1s1*b variant was nearly fixed in holstein but ranged from 0.40 t...
