Evaluating the Predictive Value of Estimated Breeding Values of Piétrain Sires for Uniformity and Survival in Their Crossbred Progeny

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT High litter sizes in pigs are associated with lower birth weights and increased within‐litter variation, which poses challenges to pig farming. Improving piglet uniformity and survival via genetic selection of terminal boars could be a strategy to enhance these traits.

New Considerations on Meiosis, Affinity and Genomic Constitution in Aneuploids and Interploid Hybrids of Urochloa P. Beauv. (Brachiaria)

Plant Breeding, EarlyView.
ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Grass species and climatic season impact on Rhipicephalus microplus temporal abundance in a tropical region

Pest Management Science, Volume 82, Issue 9, Page 8950-8962, September 2026.
The interaction between grass species and climatic season shapes the population dynamics of the cattle tick, Rhipicephalus microplus. This information highlights the potential of forage species to influence off‐host tick dynamics. Additionally, minimum temperature and minimum relative humidity were the most influential microclimatic predictors of ...

Growth bioestimulant in marandu grass cultivated in the amazon biome

Semina: Ciências Agrárias, 2020
This study aimed to evaluate the effects of a biostimulant on the morphogenesis, structure, productivity, and chemical composition of Urochloa brizantha cv. Marandu, managed under two nitrogen fertilization levels. Collections were carried out during the dry (June to September) and the rainy season (September to April).

Plant growth‐ promoting bacteria inoculation and co‐inoculation effects on Palisade grass (Urochloa brizantha cv. Marandu) in ferralsol in Amazonas State, Brazil

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Deforestation is primarily driven by three main factors the conversion of the Amazon rainforest into pastureland, agriculture, and mining, as well as land invasion. These pastures are mostly degraded, and it is necessary to restore their productive capacity. Microbial inoculants can be used to increase nutrient use efficiency. The objective of

Does the lowering strategy before the stockpiling period modify the marandu palisade grass production and structure?

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2021
The objective was to identify lowering strategies for Urochloa brizantha cv. Marandu in the beginning of the stockpiling period that increase forage production and improve the structure of stockpiled canopies.

Forage Responses and Beef Cattle Performance in Silvopasture Systems: A Meta‐Analysis of Tropical and Subtropical Regions of Brazil

Grass and Forage Science, Volume 81, Issue 3, July-September 2026.
ABSTRACT Silvopasture systems integrate tree, forage, and livestock components, offering a sustainable intensification strategy that combines environmental and productive benefits, although shading may impose constraints on forage accumulation. This study aimed to evaluate forage accumulation, nutritive value, and beef cattle performance in pastoral ...

Silicate and phosphate combinations for marandu palisadegrass growing on an oxisol

Scientia Agricola, 2007
One of the greatest problems for pasture establishment and maintenance are the extremely low concentrations of available phosphorus in soils. The objective of this study was to evaluate the influences on productive and physiologic attributes during Marandu palisadegrass (Brachiaria brizantha) establishment, following changes in phosphorus availability ...

Agronomic responses and botanical composition of warm‐season annual forages managed under contrasting harvest strategies

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Warm‐season annual (WSA) forages enhance the summer forage supply in subtropical livestock systems. The objective of this study was to determine forage mass (FM), nutritive value, nitrogen (N) yield, and botanical composition in 12 forage mixtures managed under two harvest strategies (simulated grazing vs. baleage). A randomized complete block
