Ambition meets reality: achieving GHG emission reduction targets in the livestock sector of Latin America. Repositório Alice
ARANGO, J.; RUDEN, A.; MARTINEZ-BARON, D.; LOBOGUERRERO, A. M.; BERNDT, A.; CHACÓN, M.; TORRES, C. F.; OYHANTCABAL, W.; GOMEZ, C. A.; RICCI, P.; KU-VERA, J.; BURKART, S.; MOORBY, J. M.; CHIRINDA, N..
Livestock production is a very relevant source of income and agricultural greenhouse gas (GHG) emissions in Colombia, Brazil, Argentina, Costa Rica, Uruguay, Mexico, and Peru. Several management and technological options with enteric methane mitigation potential have been evaluated and their scaling is anticipated to contribute toward achieving GHG emission reduction targets in the framework of the Paris Agreement. Yet, widespread adoption of promising mitigation options remains limited, raising questions as to whether envisaged emission reduction targets are achievable. Using findings from local studies, we explore the mitigation potentials of technologies and management practices currently proposed to mitigate enteric methane emissions from cattle...

Attractants for automated emission measurement (Greenfeed®) in pasture-based systems. Repositório Alice
MOMBACH, M. A.; CARVALHO, P. de; CABRAL, L. da S.; RODRIGUES, R. de A. R.; TORRES, R. C.; PEREIRA, D. H.; PEDREIRA, B. C. e.
This study aimed to evaluate the frequency and intensity of GreenFeed (GF) use by Nellore steers using different attractants in pastures of integrated systems. The attractant protein supplement and Tifton bermudagrass pelleted hay flavored with vanilla were evaluated over a period of 15 days. The pelleted hay stimulated the animals to stay longer in the equipment (24.23 s), with 8% more visits in intervals longer than 30 s in contrast to protein supplement. This indicates that pelleted hay flavored with vanilla is a potential attractant to encourage Nellore steers to visit GF in grazing systems.

CRAMBE CAKE (Crambe abyssinica hochst) ON LAMB DIETS Ciência e Agrotecnologia
Canova,Érika Breda; Bueno,Mauro Sartori; Moreira,Heverton Luis; Possenti,Rosana; Brás,Patrícia.
The use of alternative feedstuffs in animal diet, such as residues derived from the biodiesel production aims to increase productivity and reduce costs in animal production. Them aim of this study was to evaluate the substitution effect of 0, 22, 44 and 64% of soybean meal protein by Crambe cake (Crambe abyssinica Hochst) protein in lamb diet. In the in vivo experiment, 20 lambs were used and evaluated the apparent digestibility, nitrogen balance and voluntary DM intake. The replacement of the protein resulted in a linear decrease in apparent digestibility coefficient (ADC) of dry matter (DM), organic matter (OM), ether extract (EE), gross energy (GE), acid detergent fiber (ADF), neutral detergent fiber (NDF), cellulose (CEL) and the percentage of total...

Tem sido apontada a possibilidade de se ampliar a digestão ruminal de volumosos, especialmente dos mais fibrosos, com a inclusão de aditivo microbiano nas dietas. Neste trabalho, dois experimentos in vitro foram executados para: 1º) avaliar o potencial de adições individuais de microrganismos isolados do trato digestivo de bovinos em dieta à base de silagem de milho + silagem de cana-deaçúcar sobre a degradação ruminal da matéria seca (DMS) e o rendimento de metano (CH4) e o 2º) avaliar o potencial da adição de um dos microrganismos que se destacou positivamente no 1º experimento para melhorar parâmetros cinéticos de aproveitamento ruminal da matéria seca (MS) das forragens de quatro variedades de cana-de-açúcar. Significância estatística foi considerada...

Abstract: The objective of this study was to evaluate the effect of seasons under a tropical climate on forage quality, aswell the effect of an Urochloa brizantha cv. Marandu grazing system on enteric methane (CH4) emissions fromNellore cattle in the Southeast region of Brazil. Sixteen Nellore steers (18 months old and initial weight 318.0 ± 116.59 kg of LW; final weight 469 ± 98.50 kg of LW) were used for a trial period of 10 months, with four collection periods in winter (August), spring (December), summer (February) and autumn (May). Each collection period consisted of 28 days, corresponding to the representative month of each season where the last six days were designed for methane data collection. Animals were randomly distributed within 16...

Latin America and Caribbean (LAC) is a developing region characterized for its importance for global food security, producing 23 and 11% of the global beef and milk production, respectively. The region?s ruminant livestock sector however, is under scrutiny on environmental grounds due to its large contribution to enteric methane (CH4) emissions and influence on global climate change. Thus, the identification of effective CH4 mitigation strategies which do not compromise animal performance is urgently needed, especially in context of the Sustainable Development Goals (SDG) defined in the Paris Agreement of the United Nations. Therefore, the objectives of the current study were to: 1) collate a database of individual sheep, beef and dairy cattle records from...

Methane mitigation and ruminal fermentation changes in cows fed cottonseed and vitamin E Scientia Agricola
Nogueira,Ricardo Galbiatti Sandoval; Perna Junior,Flavio; Pereira,Angélica Simone Cravo; Cassiano,Eduardo Cuellar Orlandi; Carvalho,Roberta Ferreira; Rodrigues,Paulo Henrique Mazza.
ABSTRACT: Inherently, ruminant production of methane (CH4), a greenhouse gas (GHG), causes animal energy losses. Cottonseed is a lipid source and is used sometimes to enhance energy density in cattle diets. It also can mitigate enteric CH4. Lipids release peroxides in the rumen, and antioxidants have the ability to neutralize them. Thus, a lipid and antioxidant source can benefit rumen fermentation. The aim of this study was to evaluate rumen fermentation parameters from cows fed cottonseed and vitamin E. Six cannulated cows were arranged in a replicate 3 × 3 latin square. Treatments were: 1) Control, 2) CS (30 % corn replaced by cottonseed) and 3) CSVitE (30 % corn replaced by cottonseed, plus 500 IU VitE). Results were compared by orthogonal contrast....

Phenotypic association among performance, feed efficiency and methane emission traits in Nellore cattle. Repositório Alice
SAKAMOTO, L. S.; SOUZA, L. L.; GIANVECCHIO, S. B.; OLIVEIRA, M. H. V. DE; SILVA, J. A. II DE V.; CANESIN, R. C.; BRANCO, R. H.; BACCAN, M.; BERNDT, A.; ALBUQUERQUE, L. G. DE; MERCADANTE, M. E. Z..
Enteric methane (CH4) emissions are a natural process in ruminants and can result in up to 12% of energy losses. Hence, decreasing enteric CH4 production constitutes an important step towards improving the feed efficiency of Brazilian cattle herds. The aim of this study was to evaluate the relationship between performance, residual feed intake (RFI), and enteric CH4 emission in growing Nellore cattle (Bos indicus). Performance, RFI and CH4 emission data were obtained from 489 animals participating in selection programs (mid-test age and body weight: 414±159 days and 356±135 kg, respectively) that were evaluated in 12 performance tests carried out in individual pens (n = 95) or collective paddocks (n = 394) equipped with electronic feed bunks. The sulfur...

N..
ABSTRACT: Successful mitigation efforts entail accurate estimation of on-farm emission and prediction models can be an alternative to current laborious and costly in vivo CH4 measurement techniques. This study aimed to: (1) collate a database of individual dairy cattle CH4 emission data from studies conducted in the Latin America and Caribbean (LAC) region; (2) identify key variables for predicting CH4 production (g d−1) and yield [g kg−1 of dry matter intake (DMI)]; (3) develop and cross-validate these newly-developed models; and (4) compare models' predictive ability with equations currently used to support national greenhouse gas (GHG) inventories. A total of 42 studies including 1327 individual dairy cattle records were collated....
