Legacies of domestication, trade and herder mobility shape extant male zebu cattle diversity in South Asia and Africa

open access: yesScientific Reports, 2018
All tropically adapted humped cattle (Bos indicus or “zebu”), descend from a domestication process that took place >8,000 years ago in South Asia. Here we present an intercontinental survey of Y-chromosome diversity and a comprehensive reconstruction of ...

Feed restriction of F1 Holstein × Zebu cows in the final third of lactation modifies intake, nutrient digestibility, feeding behavior, and performance

open access: yesRevista Brasileira de Zootecnia, 2019
The objective of this study was to evaluate the effect of quantitative feed restriction level on nutrient intake and digestibility, nitrogen balance, efficiency and feeding behavior, and productive performance of F1 Holstein × Zebu cows in late lactation.

Madagascar's grassy biomes, from Holocene to Anthropocene

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Madagascar's grassy biomes cover 80% of the island and are central to Malagasy history, culture and ecology. The research community continues to debate the extent to which these biomes are ancient ecosystems or products of human‐driven deforestation and the implications for ecosystem management.

Production objectives, trait and breed preferences of farmers keeping N'Dama, Fulani Zebu and crossbred cattle and implications for breeding programs.

open access: yesAnimal, 2017
Many local livestock breeds in developing countries are being replaced by exotic breeds, leading to a loss of genetic resources. In southern Mali, for the past two decades, a trend towards increasing crossbreeding between the trypanotolerant N'Dama ...

Lower jaw fracture in a Zebu × Brown Swiss calf due to attack by domestic dogs (Canis familiaris)

open access: yesVeterinary Record Case Reports, EarlyView.
Abstract The objective of this report is to describe the case of a calf attacked by domestic dogs, which caused an incomplete fracture of the left lower jaw, resulting in bone exposure within the oral cavity. Clinical evolution is described 3 months post‐attack. The exposed portion of the fractured bone was removed, as well as two small bone fragments.

Enteric methane emissions, energy partitioning, and energetic efficiency of zebu beef cattle fed total mixed ration silage

open access: yesAsian-Australasian Journal of Animal Sciences, 2018
Objective The main objective of this study was to evaluate the effect of different feeding levels of a total mixed ration silage-based diet on feed intake, total tract digestion, enteric methane emissions, and energy partitioning in two beef cattle ...

In vitro digestibility of Urochloa decumbens inoculated with fungi isolated from the gastrointestinal tract of sheep

open access: yesAnnals of Applied Biology, EarlyView.
The forage digestibility decreases in the dry season. Fungus isolates from the gastrointestinal tract of healthy sheep were evaluated. Aspergillus terreus isolate was identified by analysis of rDNA and encoding β‐tubulin gene and Trichoderma longibrachiatum was identified by analysis of rDNA and elongation factor 1‐α gene. The T.

Caractérisation morphobiométrique du zébu Djelli du Niger

open access: yesInternational Journal of Biological and Chemical Sciences, 2019
Le zebu peul (zebu Djelli) est l’une des races bovines qui constitue les cinq groupes (5) du cheptel bovin du Niger. Il est tres apprecie de par ses aptitudes zootechniques, mais son elevage est plus localise dans les departements et communes riveraines ...

Genetic Relationships Among Resilience, Fertility and Milk Production Traits in Crossbred Dairy Cows Performing in Sub‐Saharan Africa

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Change in climate over the past years and its impact on the environment have necessitated the inclusion of resilience traits in the breeding objectives of dairy cattle. However, the relationship between resilience and other traits of economic importance in dairy production is currently not well known. This study examined the genetic parameters
