IGC Proceedings (1977-2023)
A recent advance using molecular biology has identified a transcription factor or master switch that can ‘turn on’ the condensed tannin pathway present in white clover, and with the appropriate promoters allows biologically significant levels of condensed tannin expression in leaf tissue. In vitro tests have demonstrated that the condensed tannins produced in white clover leaves can bind protein at a pH 6.5, as found in the rumen, and then release them at pH 2.5, the pH in the abomasum, before entering the small intestine for amino acid absorption. Additional tests have demonstrated that these condensed tannins can reduce methane …

IGC Proceedings (1977-2023)
The production of fodder beet (Beta vulgaris L.) in New Zealand is concentrated in the South Island, and often requires irrigation to achieve high yields. Development of efficient irrigation management strategies requires information on the effect of timing and rate of irrigation on crop growth. A field study was conducted on a moderately deep soil at Chertsey, Canterbury, New Zealand, to evaluate crop growth responses to five irrigation managements: Rain-fed (control), weekly replacement of full evapotranspiration (FullET-weekly), and 50% of evapotranspiration replaced weekly (HalfET-weekly), fortnightly (HalfET-2weekly) or 3-weekly (HalfET-3weekly). Irrigation to replace ET was adjusted to account for rainfall …

Maintain Forage Yields In Long- And Short-Term Grasslands In Norway, I. Sturite, T. Maeland, M. Höglind
IGC Proceedings (1977-2023)
Various reasons have been invoked explaining the low renovation activity in Norwegian grassland farming: swards are often located in marginal areas, ploughing and reseeding gives low or no yield in the renovation year, and it may be unprofitable to establish a new sward. The establishment of new leys can also prove difficult in seasons with unfavourable weather conditions. Thus, farmers prefer long-term or permanent swards as opposed to ploughed and reseeded swards. The hypotheses of this study is that under equal management conditions, permanent and temporary swards (leys) that are reseeded frequently are equally productive. We present results from an …

Comparison Of Four Maize Cultivars (Zea Mays L.) As Winter Forage In Sudan, Rihab El Zubair
IGC Proceedings (1977-2023)
Winter forage availability in Sudan is constrained by lack of a suitable annual winter forage crop. The main forage crop grown is Abu70 (Sorghum bicolor) which is a summer crop that yields 7.6-8.4 t/ha in summer but much less in winter. There is, therefore, need for a winter high yielding forage crop that exceeds Abu70 in productivity and quality. This study was aimed to evaluate four forage maize cultivars as potential winter crops in central Sudan in terms of productivity and quality. An experiment was conducted using four maize forage cultivars. The experiment lasted for two consecutive seasons …

Diet Selection By Goats At Kalemando, North Darfur, Sudan, Abdelrahim I. H. Mansoor, Babo Fadlalla
IGC Proceedings (1977-2023)
Pressure on rangelands of Sudan has increased in the last few decades due to increase in human population and in animal numbers. The rangelands were also impacted by climate change, desertification, agricultural expansion, mining, and overgrazing. Decreased amounts of rainfall have impoverished the natural rangelands. Goats are capable of grazing on semi-desert regions characterized by low rainfall and scarce grazing plants. It is therefore necessary to know and enhance plant species preferred by goats to properly manage the rangelands. The present study was conducted at Kalemando, North Darfur State during the rainy season of year 2017 when most plants were …

IGC Proceedings (1977-2023)
Forage production is at the core of improved livestock productivity, especially in sub Saharan Africa. The genetic potential of existing animals remains underutilized due to limited forage quality and quantity. Albeit wide range of forage germplasm that exists, little data is available for identifying suitable genotypes, matched to specific environments and production systems. Due to the spatial and temporal diverse environments in which livestock production happens, multi-locational screening of forage production and characterizing genotype by environment interaction is key. We selected seven Urochloa (Syn. Brachiaria) genotypes comprising three hybrids and four cultivars and established them in on-farm trials in …

A study was conducted to evaluate growth and productivity of eight improved Urochloa grass cultivars in lower midlands, upper midlands and lower highlands agro-ecological zones (AEZ) in Eldoret, Kitale and Alupe respectively, western Kenya. The grass cultivars were; Urochloa brizantha cvs. Marandu, Xaraes, Piata, and MG-4, U. decumbens, cv. Basilisk, U. humidicola cvs. Humidicola and Llanero and Urochloa hybrid cv. Mulato II. Rhodes grass (Chloris gayana) and Napier grass (Pennisetum purpureum cv. Kakamega 1) were included as controls. At establishment …

Crude protein and digestible dry matter are the most important components of a feed and determine animal performance. The natural pastures in Kenya are prone to great seasonal and spatial fluctuation in both quality and quantity. Consequently, there was need to explore other nutritious alternative feeds. Sixteen growing male Galla goats weighing 10 - 24 kg were used in a twelve weeks feeding trial in the coastal lowlands of Kenya. They were randomly allocated four grass diets consisting of Urochloa brizantha cvs. Piata and MG4, U. hybrid cv. Mulato II and Chloris gayana (Rhodes grass), which was used as the …

Grass pastures in monoculture are the predominant system in transition zone climates, where warm-season perennial grasses are usually cultivated. Mixed grass-legume pastures are worldwide recognized for having advantages over pure stands, including pasture longevity, N input from biological fixation, efficient nutrient cycling, and greater animal production. The genus Arachis encompasses important and successful warm-season forage legume species cultivated in mixed pastures or in pure stands. Arachis pintoi and Arachis glabrata are potential tropical forage species that can be used in transition zone climates. Mixed pastures with these legumes have been shown to be resilient systems, able to withstand short-term perturbations, …

Warm-season (C4) perennial grasses are grown over millions of hectares in the Southeastern United States. These grasses produce optimal growth at 30 to 38°C diurnal temperature. Bermudagrass (Cynodon sp.) has been adopted as the preferred forage for many livestock and hay producers. Compared to other native and introduced warm-season perennial grass species, improved bermudagrass varieties produce high biomass with enhanced digestibility for ruminant grazing or feed. Until the 1930’s pastures in the region consisted of unimproved ‘common’ bermudagrass (Cynodon dactylon (L.) Pers.) that had been introduced earlier. However, in the early 20th century, new germplasm, including stargrass …
