Libido de touros Nelore: efeito da proporção touro: vaca sobre a taxa de gestação

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2003
Estudou-se a influência da libido de touros sobre as taxas de gestação de vacas aos 30, 60 e 90 dias de estação de monta, e avaliaram-se as correlações entre concentração de testosterona, qualidade seminal e libido.

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Towards biocultural approaches to environmental education—Evidence from Madagascar

Conservation Science and Practice, EarlyView.
This research illustrates how biocultural approaches can facilitate the decolonisation of environmental education projects across Madagascar. Abstract Environmental education projects are commonly used by conservation organizations to improve the relations between humans and nature.

Tolerance for jaguars among ranching communities in the Colombian Llanos

Conservation Science and Practice, EarlyView.
Livestock protection measures are often implemented with the desired outcome of reducing retaliatory killings. We studied drivers of retaliatory killings in four communities in the Colombian Llanos and evaluated whether an electric fencing intervention would improve tolerance for jaguars.

Squamous metaplasia of the rete ovarii in a Zebu cow [PDF]

BMC Veterinary Research, 2012
Stratified keratinizing squamous epithelium in the ovary has been associated with the diagnosis of ovarian teratoma in cows. Recently, the diagnosis of "epidermoid cyst" has been proposed. A case of squamous metaplasia of the rete ovarii in a Zebu cow is described in this report.A crossbreed Zebu cow had both ovaries enlarged with multiple cysts.

Resistance of zebu cattle (Bos indicus) to colonization by major ruminant hoof pathogens. [PDF]

Zebu cattle (Bos indicus) is reported to be more resistant towards harmful environmental factors than taurine cattle (Bos taurus). A few hundred zebu cattle are kept in Switzerland and in contrast to the Swiss indigenous breeds, infectious hoof disease ...

Genetic Associations of Functional Longevity With Sexual Precocity and Growth Traits in Nellore Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Functional longevity (FL) is a complex trait that integrates many attributes directly contributing to the successful retention and productivity of a cow within the herd. Consequently, improving FL in beef cattle increases herd profitability. This study aimed to estimate the genetic associations between two alternative FL definitions and traits

Follicular dynamics in zebu cattle [PDF]

Pesquisa Agropecuária Brasileira, 2000
The aim of this study was to investigate the follicular dynamics during estrous cycle in Gir breed (Bos indicus) cows. Follicular growth and atresia during estrous cycle were evaluated using a portable ultrasound device. Luteal activity was evaluated by serum progesterone levels.

Genetic Evaluation for Functional Longevity in Nellore Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Stayability (STAY) presents limitations in capturing genetic variability among animals with varying calving records up to 76 months of age. Furthermore, because STAY is measured late in life (typically at 6 years of age), it inherently prolongs generation intervals.
