IGC Proceedings (1977-2023)

Warm-season perennial grasses are the backbone of the pasture-based livestock industry in the southeastern USA. In Florida specifically, bahiagrass (Paspalum notatum Flugge) and bermudagrass (Cynodon spp.) support 1 million head of cattle and 15,000 beef cattle operations. Bermudagrass is the most widely planted forage species in the southeastern USA, planted in approximately 15 million ha and used for grazing, hay and silage. The genus Cynodon is native to southern Africa and germplasm collections have revealed a high degree of genetic variability within the genus. The United States Department of Agriculture National Plant Germplasm System (USDA-NPGS) maintains a collection …


Relationship Between Semi-Arid Rangelands Quality Parameters And Vegetation Indexes, P. Toro-Mujica, D. Enriquez-Hidalgo, S. Escobar Feb 2022

Relationship Between Semi-Arid Rangelands Quality Parameters And Vegetation Indexes, P. Toro-Mujica, D. Enriquez-Hidalgo, S. Escobar

IGC Proceedings (1977-2023)

A large portion of the sheep production systems in the semi-arid zone of Central Chile base their feeding on the rangelands, adjusting both the production cycle and the use of supplementary feed to the natural supply of fodder. In this way, knowledge of the rangeland quantity and quality at the farm level emerges as an essential input for the decision-making of feed management. The objective of the study was to relate the herbage quality parameters of the semi-arid zone rangeland with Vegetation Indices (VI) and to determine which vegetation index report the best results. Vegetative indexes were obtained from aerial …


Predicting Forage Intake By Sheep Through The Pampa Corte Model Or Nrc, C. A. Pozo, Gilberto V. Kozloski, H. M. N. Ribeiro Filho, J. F. Tourrand, Vicente Celestino Pires Silveira Feb 2022

Predicting Forage Intake By Sheep Through The Pampa Corte Model Or Nrc, C. A. Pozo, Gilberto V. Kozloski, H. M. N. Ribeiro Filho, J. F. Tourrand, Vicente Celestino Pires Silveira

IGC Proceedings (1977-2023)

The aim of the present study was to evaluate the precision and accuracy of the Pampa Corte and National Research Council (2007; NRC) models for predicting forage intake (FI) by sheep. Individual data (n = 213) of observed FI, body weight and chemical composition of consumed diet were taken from fifteen indoor digestibility trials conducted with male sheep housed in metabolic cages and fed only forage ad libitum. The diets were composed of tropical grasses, temperate grasses and legumes. Individual observations of FI were averaged by treatment (n = 32) into each experiment which were then compared to FI …


Performance Of Napier Grass (Cenchrus Purpureus L.) Genotypes Grown Under Limited Soil Moisture, E. Habte, M. S. Muktar, A. T. Negawo, A. M. Sartie, C. S. Jones Feb 2022

Performance Of Napier Grass (Cenchrus Purpureus L.) Genotypes Grown Under Limited Soil Moisture, E. Habte, M. S. Muktar, A. T. Negawo, A. M. Sartie, C. S. Jones

IGC Proceedings (1977-2023)

Napier grass (Cenchrus purpureus Schumach L.) is an important perennial forage native to Africa and grown in many tropical and subtropical countries. It is considered as a short-term drought tolerant forage which is a useful trait in areas that are characterized by low precipitation during the dry season. To exploit the potential of this grass and identify water use efficient (WUE) genotypes, a field drought stress trial was conducted at Bishoftu, Ethiopia. Eighty-four Napier grass genotypes were planted in a p-rep design in four replications. The genotypes were evaluated for forage performance during the dry season of 2019 and …


Pasture Utilization At Islands In Northern Norway, V. Lind, Ø. Holand, F.-A. Haugen, G. Steinheim Feb 2022

Pasture Utilization At Islands In Northern Norway, V. Lind, Ø. Holand, F.-A. Haugen, G. Steinheim

IGC Proceedings (1977-2023)

The Norwegian sheep industry is based on utilization of “free” rangeland pasture resources. Use of mountain pastures is dominating, with about two million sheep grazing these pastures during summer. Regional challenges related to e.g., loss of sheep to large carnivores make farmers think differently. The Norwegian coastline is among the longest globally and is scattered with islets and islands. Alone along the coast of Nordland county, it is estimated more than 14,000 islands. Use of islands for summer pasture is an alternative but there is a limited knowledge about such a management system. In this study, we examined lambs’ average …


Performance Of The Leucaena Leucocephala–Megathyrsus Maximus Cv Mombasa System And Local Range Grazed By Pelibuey Ewe-Lambs, E. Cortés Díaz, J. C. Campos Ojeda, P. Martínez Hernández, J. L. Zaragoza Ramírez Feb 2022

Performance Of The Leucaena Leucocephala–Megathyrsus Maximus Cv Mombasa System And Local Range Grazed By Pelibuey Ewe-Lambs, E. Cortés Díaz, J. C. Campos Ojeda, P. Martínez Hernández, J. L. Zaragoza Ramírez

IGC Proceedings (1977-2023)

Mombasa grass and leucaena have shown an excellent agronomic performance grown in tropical semi-arid ranges, the objective of this study was to compare the agronomic performance of Leucaena-Mombasa grown as a silvopastoral system at two leucaena plant densities (10000 and 15000 plants ha-1) and of Pelibuey ewe-lambs grazing it against native unimproved tropical semi-arid range of the state of Morelos, México. Experimental design was a completely random with two replications. Unimproved native range was mainly deciduous shrubs and mixed herbaceous plants (Poaceae and Asteraceae). Stocking rate was the same across treatments and grazing lasted all rainy season. Of …


Participatory Evaluation Of Urochloa And Megathyrsus Forage Species In Western Kenya: Farmers Perspective, Ruth Odhiambo, Solomon Mwendia, David Mwangi, Alfred Juma, An Notenbaert Feb 2022

Participatory Evaluation Of Urochloa And Megathyrsus Forage Species In Western Kenya: Farmers Perspective, Ruth Odhiambo, Solomon Mwendia, David Mwangi, Alfred Juma, An Notenbaert

IGC Proceedings (1977-2023)

Despite western Kenya potential in dairy production, it has lagged behind compared to other regions in the country. This comes against growing per capita milk consumption in Kenya currently estimated at 120 litres per person per year. As a result, western Kenya is largely net importer of milk from neighbouring counties albeit the possibility improving productivity within. Among the most prevalent constraint to increased productivity is limited forage quality and quantity throughout the year. Napier stunting disease, which suppresses forage production from Napier grass, the most prevalent cultivated forage in western Kenya, exacerbates this. To contribute to addressing the problem, …
