Intake, Growth And Feed Preference By Steers Fed Combinations Of Alfalfa And Annual Ryegrass Silage, E Charmley
IGC Proceedings (1997-2023)
Nutritive value and intake of legumes is generally considered superior to grasses when ensiled at similar digestibility. The objectives of this experiment were to determine the optimum combination of annual ryegrass (Lolium multiflorum) and alfalfa (Medicago sativa) silages to maximize growth rate of steers fed silage, determine chemical components which influenced performance, and to determine if steers selected the optimum mixture when given a choice. Both silages contained similar concentrations of dry matter, acid detergent fibre and organic acids, but alfalfa silage had higher concentrations of nitrogen (N), soluble N and ammonia N. Annual ryegrass contained …

Effects Of A New Cellulase Derived From Acremonium On Silage Fermentation, K Atakul, A Aniwaru, N Narasaki, E No, E Chase
IGC Proceedings (1997-2023)
Alfalfa (Medicago sativa L) and timothy (Phleum pratense L) were ensiled in laboratory silos to evaluate the effect of cellulase derived from Acremonium (0, 0.005, 0.01, and 0.02% to alfalfa and 0, 0.006, 0.012, and 0.024% to timothy) on silage fermentation. In alfalfa, the addition of cellulase inhibited the production of butyric acid, and as the percentage of cellulase increased, the concentration of ammonia decreased and the content of lactic acid increased. The dry matter recovery significantly decreased with the addition of cellulase. The quality of timothy silage also increased due to the absence of butyric acid. The …

Ensilage For Low Resources Farmers 1. Drum, Wirebasket And Pit As Silos, F.H. K. Asiedu, C A. Alexander, G Proverbs
IGC Proceedings (1997-2023)
King grass (Pennisetum purpureum x P. americanum) was ensiled in metal drum, wirebasket and pit silos in a randomized block design with eight replications in order to determine whether the silos produced silage of the same quality and at the same cost. Pit silage had the most desirable characteristics, followed by drum silage. Moisture content (708 v 718 and 741 g/kgDM for drum and wirebasket respectively), pH (5.18 v 5.65 and 5.77), ammonia nitrogen (137 v 149 and 164 g/kgDM), and butyric acid (8.5 v 11.2 and 14.6 g/kgDM) were lowest, while lactic acid (28.2 v 26.3 and …

Ensilage For Low Resources Farmers 2. Poultry Litter As Cheap Additive, F.H K. Asiedu, C A. Alexander, G Proverbs
IGC Proceedings (1997-2023)
The effect of poultry litter (15% wet basis) additive on the quality of king grass (Pennisetum purpureum x P. americanum) silage was studied in a randomized block design experiment (8 replications). Compared with grass silage (G), grass + poultry litter (G+P) caused significant (P<0.05) reduction in moisture (G, 716 v G+P, 670 g/ kgDM), pH (5.41 v 4.72) and butyric acid (9.6 v 5.5 g/kgDM). Crude protein (CP, Nx6.25, g/kgDM), in vitro digestibility (IVOMD, g/ kgDM) and metabolizable energy (ME, MJ/kgDM) increased from (G)104, 536 and 8.00 to (G+P) 127, 613 and 9.19. In a feeding trial using St. Elizabeth x Barbados Blackbelly lambs G+P gave significantly (P<0.05) higher daily gain (182 v 149 for G). This was related to significantly (P<0.05) higher intake of CP and ME from G+P (71.9 v 55.1 g/d and 5.20 v 4.24 MJ/d).

Influence Of Addition Of Previously Fermented Juice To Alfalfa Ensiled At Different Moisture Contents, M Ohshima, L M. Cao, E Kimura, Y Ohshima, H Yokota
IGC Proceedings (1997-2023)
Alfalfa (Medicago sativa L.)was ensiled with or without previously fermented juice (PFJ) after wilting for 0, 3, 6 and 24 h. They were ensiled in 900ml glass bottles at 400g/800cm3 and preserved at 25°C for 45 d. The moisture content of the silages were 810, 730, 690 and 580g/kg, respectively. The PFJ was prepared by macerating 200g of freshly harvested alfalfa with 1,000ml of water, filtering through double cheese cloth, adding 20g/l sucrose and incubating anaerobically at 30°C for 2 d. They were added 2.5ml/kg of chopped alfalfa. Lactic acid fermentation of silage was enhanced bAlfalfa (Medicago sativa …
Additives As Preservatives For Wrapped Round Bales Silage Made Under Tropic Climate, J M. Paillat, G Mandret
Additives As Preservatives For Wrapped Round Bales Silage Made Under Tropic Climate, J M. Paillat, G Mandret
IGC Proceedings (1997-2023)
In tropical highlands it is difficult to conserve harvested forage as silage. Tests with molasses as an additive, or using ammonium tetraformiate (ATF) or inoculants have been conducted to find out more about the fermentation process in these conditions. Sugar additives are not the primary factor in the fermentation process. Nevertheless, they are essential to make up for the small amounts of water soluble carbohydrates (WSC) in the forages, but only if the dry matter (DM) content is high enough (27% for temperate species, 40 % for the kikuyu grass). Even at high rates such as 5 l t-1 of …
Effect Of Slurry Application On Cell Wall Components And Silage Intake By Sheep Of Italian Ryegrass And Triticale, H Kawamoto, N Shimizu, R Uegaki, R Kobayashi
Effect Of Slurry Application On Cell Wall Components And Silage Intake By Sheep Of Italian Ryegrass And Triticale, H Kawamoto, N Shimizu, R Uegaki, R Kobayashi
IGC Proceedings (1997-2023)
The study was to elucidate the effect of application of slurry manure from dairy cows on chemical components, the rumen degradation characteristics and silage intake by sheep of Italian ryegrass (Lolium multiflorum Lam.) and Triticale ( rye-wheat hybrid). The amounts of application of slurry were 0, 50, 100 and 150 t/ha. The increasing level of slurry application resulted in a decrease of lower digestible cell wall and an increase of degradation rate. The silage of 150 t /ha treatment was significantly more consumed by sheep than the other treatments (p<0.05). The changes in cell wall components in both quantity and quality by the slurry application were advantageous to the increase of voluntary dry matter intake of the forage.

The Combined Role Of Microbes And Forages In Animal Productivity, K. Panke-Buisse
IGC Proceedings (1997-2023)
Agricultural systems, particularly ruminant systems, are underpinned by diverse, functional microbial communities—in the soil, forage, silo, and rumen. We have relied on the jobs they perform on our behalf, but only recently have we been able to look “under the hood” at the membership and mechanisms within these microbiomes and begin to think about optimization. Ensiling is a common method of forage preservation globally and represents a highly intensive intersection between forage and microbiology, which has been shown to have beneficial effects on forage quality and dairy animal performance. However, observations of enhanced productivity, especially in the context of inoculated …
The Partial Replacement Of Perennial Ryegrass Silage With Ensiled Biorefined Perennial Ryegrass Press Cake, And Its Impact On Productivity Of Late Lactation Dairy Cows, H. Costigan, B. Lahart, M. Kennedy, T. Rumley, L. Shalloo
The Partial Replacement Of Perennial Ryegrass Silage With Ensiled Biorefined Perennial Ryegrass Press Cake, And Its Impact On Productivity Of Late Lactation Dairy Cows, H. Costigan, B. Lahart, M. Kennedy, T. Rumley, L. Shalloo
IGC Proceedings (1997-2023)
Although necessary to maintain milk production in late lactation when grass is scarce, dependency on imported concentrate has negative environmental credentials; diversifying native feeds i.e., perennial ryegrass, using biorefinery, to produce high quality by-products may be a solution (Sanders et al., 2020). To validate these suggestions, a study was undertaken on dairy cows during the winter period; 60% of a perennial ryegrass silage diet was replaced with perennial ryegrass (PRG) press cake in treatment cows (GSPC; n=20), while a perennial ryegrass silage diet was offered to control cows (GS; n=20). Cows substituted with press cake produced 9.1 and 10.5 % …

Breeding Small Grains As A Forage, Silage And Cover Crop For The Southern Coastal Plain (Usa) In A Changing Climatic Environment, A. Blount, Marcelo O. Wallau, S. A. Harrison, Cheryl L. Mackowiak, A. Babar, José C. B. Dubeux Jr.
IGC Proceedings (1997-2023)
Forage breeding of small grains in the southern Coastal Plains region of the U.S. mimic many other countries experiencing climate changes and breeding strategies should be similar for improving small grains grown for forage, silage or as cover crops. Significant focus on improvements in stress-adaptation has encouraged members of the SunGrains cooperative to cross, evaluate and develop experimental lines with inherent adaptation to climatic conditions including heat stress, drought tolerance, short-day and long-day forage production periods, and flooded conditions for events with storm-related, short-term durations. Many new cultivars, grown throughout the southeastern U.S. have resulted from breeding selection under abiotic …

Using A Radiometric Method To Determine The Silage Density In Bunker Silos, Thomas Hoffmann, Andree Jacobs
IGC Proceedings (1997-2023)
Certain minimum densities should be targeted when storing silage in bunker silos. Often the minimum density is not reached. As a result, high losses can occur. This study aims to develop a measuring device for online density measurement. The basis of the measuring device is a source of caesium radiation with an activity of 37 MBq and a sodium iodide scintillation detector. The measuring device uses the backscattering method. Source and detector are arranged in a measuring wheel, which is connected with the tractor via the rear three-point linkage. Both, the current density as well as the density increase in …

Characteristics Of Lactic Acid Bacteria Strains Isolated From Tibetan Plateau And Their Effects On Silage Quality Of Italian Ryegrass (Lolium Multiflorum Lam.) At Low Temperature, Siran Wang, Mudasir Nazar, Niaz Ali Kaka
IGC Proceedings (1997-2023)
Temperature is an important factor affecting ensilage. In cold regions, low temperature could be an adverse environmental factor during ensiling. However, little research has focused on improving silage quality at low temperatures. This study aimed to examine two lactic acid bacteria (LAB) strains (LCG9 and TG1) isolated from the Tibetan Plateau, and evaluate their effects on the silage quality of Italian ryegrass (Lolium multiflorum Lam.) at three temperatures (10° C, 15° C and 25° C). The isolated strains and one commercial inoculant (G, Lactobacillus plantarum MTD-1) were evaluated by morphological, physiological and biochemical tests. Strains G, LCG9, TG1 and …

Evaluation Of Sweet Grain Sorghum Silage For Dairy Cows As An Alternative To Irrigated Maize Silage, W. G. Do Nascimento, Y. Barrière, X. Charrier, Christian Huyghe, J. C. Emile
IGC Proceedings (1997-2023)
Under European dairy cattle rearing conditions, whole plant maize silage is the main part of the dairy cow's diet especially during the winter season. Nevertheless maize production can be limited in some areas because summer rainfall is insufficient and so irrigation is necessary. Grain sorghum hybrids, and especially sweet sorghum types, are potentially of great interest to avoid this water consumption (Lemaire et al., 1996, Legarto, 2000). For this reason we evaluated in 2003 the benefits and limits of a sweet grain sorghum silage for dairy milk production, compared to an irrigated maize silage. We paid particularl attention to …

The Role Of The Phare Programme And The Danish-Lithuanian Project On The Development Of The Grassland Production And Of Dairy-Beef Cattle Husbandry, V. Vrotniakiene, Jonas Jatkauskas
IGC Proceedings (1997-2023)
Animal production is one of the priorities for economic development in Lithuania. Dairy-beef cattle husbandry has remained an important branch of animal production under the conditions of agricultural reform. Favorable agroclimatic conditions for grass cultivation, old traditions of agricultural production and the ability to train farmers in new techniques creates good conditions for the development of dairy-beef cattle husbandry. It is most appropriate to use cattle types suitable for grass feeding with low inputs of concentrates. This paper reports on two development projects that sought to increase animal production through grassland improvement and the production of high-quality silage.

Utilisation Of Whole-Crop Rice Silage As A Feed For Ruminants, N. Yoshida, M. Ogawa, Y. Cai, H. Nemoto, M. Ishida
IGC Proceedings (1997-2023)
A national project on the utilisation of whole-plant rice (Oryza sativa L.) as a feed has developed in Japan since 2000. The use of a home-produced forage may be useful to reassure consumers concerned with risks of BSE and foot and mouth disease. Furthermore, Japanese farmers have been obliged to convert one million ha of paddy field from rice to other crops.

The Potential Of Different Forage Combinations For Green-Chop Silage, Trevor L. Knight, Tom J. Fraser, T. A. White, M. G. Hyslop
IGC Proceedings (1997-2023)
On the Canterbury Plains of New Zealand (NZ) there is an opportunity on cropping farms, between summer harvest and autumn/winter sowing, to grow forage crops to make high quality silage. Recently, cereal cultivars have been specifically bred for forage production and suitability for whole-crop silage (de Ruiter et al. 2002), and also high legume (e.g. sulla) content forage mixes have resulted in high quality silages with high lactic acid and soluble carbohydrate content (Niezen et al. 1998). This trial aimed to determine the yield potential of various cereal/legume forage mixtures summer sown and harvested for silage in autumn.

Ensiling Characteristics And Ruminal Degradation Of Italian Ryegrass With Or Without Wilting And Added Cell Wall Degrading Enzymes, Z. Yu, Jianguo Han, Z. He, X. Qingfang, B. Chunsheng, N. Nishino
IGC Proceedings (1997-2023)
The previous experiment (Yu zhu et al.,1999) has shown that the efficacy of added enzymes varied greatly according to the DM content of the material crop. The silage DM did not alter the effects of enzymes on the in vitro digestion of NDF (Yu zhu et al.,1999, Yu zhu et al.,2000). The aim of this experiment was to study the effect of wilting and enzymes on fermentation quality, chemical composition and in situ digestion of Italian ryegrass (Lolium multiflorum Lam.) silage.

Ensiling Characteristics And Nutritive Value Of Browse/Maize Forage Mixtures, F. B. Bareeba, H. Kato, Elly N. Sabiiti
IGC Proceedings (1997-2023)
The practice of growing fodder tree and shrubs is being advocated for and adopted in smallholder dairy production systems. In Uganda, Calliandra calothyrsus, Gliricidia sepium, and Leucaena leucocephala have been identified and recommended as the most suitable species (Sabiiti, 2001). However tree foliage contains toxic compounds (Lowry, 1990), which may be alleviated by ensiling. The objective of the experiment was to study the ensiling characteristics of browse/ maize forage mixtures and their nutritive value when fed to lactating dairy cows.

Investigation Into Differences In Palatability Among Festulolium Varieties As Haylage, E. Touno, S. Kushibiki, H. Shingu, A. Oshibe
IGC Proceedings (1997-2023)
In Japan, paddy fields that are no longer used for cultivation of rice are being converted to cultivation of forage crops. Therefore, grass with greater wet resistance and higher quality is required. Festulolium is an interspecific hybrid between the Lolium and Festuca species and combines the characteristics of high-quality ryegrass and resistance to hostile environments from fescues (Thomas & Humphreys, 1991). Among festulolium varieties, there is wide variation in environmental resistance and feeding value. One festulolium variety, Paulita, shows superior wet resistance to Evergreen and the total digestible nutrients of Evergreen was similar to that of cocksfoot (cv. Kitamidori) (Touno …

The Feeding Value Of Silage Made From Peas Grown Alone Or In Mixture With Cereals, A. Kirilov
IGC Proceedings (1997-2023)
The interest in pea as a forage crop rich in protein does not decrease. In areas frequent summer drought pea (Pisum sativum) as a whole plant for forage gives assured yield and may be used for zero grazing, hay or silage. The winter varieties use winter-spring soil moisture better and give higher yield than the spring varieties, but they lodge, so it is necessary to sow them with supporting cereal crops to increase lodging resistance. The objective of the study was to compare the intake, digestibility, energy value and quality index of two wilted silage made from winter …
Whole Crop Cereal Silage In Dairy Production, J. Wallsten, L. Ericson, K. Martinsson
Whole Crop Cereal Silage In Dairy Production, J. Wallsten, L. Ericson, K. Martinsson
IGC Proceedings (1997-2023)
Whole-crop cereal silages (WCCS) are used to some extent in Sweden, but knowledge about the use of this feed for high yielding dairy cows is scarce. The crop is often harvested at different stages of maturity, from heading to yellow ripeness, which gives forages that differ in chemical composition. The purpose of this trial was to compare intake and milk production of dairy cows fed a WCCS based on barley harvested at three different stages of maturity.
A Simple Method For The Correction Of Fermentation Losses Measured In Laboratory Silos, F. Weissbach
A Simple Method For The Correction Of Fermentation Losses Measured In Laboratory Silos, F. Weissbach
IGC Proceedings (1997-2023)
Dry matter (DM) losses caused by formation of gaseous fermentation products can be measured by different methods. The most common method (A) is measuring the difference between the DM input and output of a silo. Other methods are based on the measurement of the fermentation gases which spontaneously leave the silo, either directly by collecting them (B) in a special absorbent like KOH or, much more easily, by weighing the filled silo at the beginning and the end of the fermentation process (C). The figures obtained by B and C are substantially smaller than those by A. This difference represents …
Ensiling Characteristics Of Sudangrass Silage Treated With Green Tea Leaf Waste Or Green Tea Polyphenols, M. Kondo, K. Kita, H. Yokota
Ensiling Characteristics Of Sudangrass Silage Treated With Green Tea Leaf Waste Or Green Tea Polyphenols, M. Kondo, K. Kita, H. Yokota
IGC Proceedings (1997-2023)
Green tea waste (GTW), emitted from beverage companies manufacturing tea drinks, contains high crude protein (CP) and polyphenols. Kondo et al. (2004) showed that GTW addition to forage ensiling enhanced lactic acid fermentation and decreased pH value. Ishihara et al. (2001) showed that high counts of Lactobacillus species were maintained and the counts of clostridia were decreased in the intestinal microflora of animals fed the diet containing green tea polyphenols (GTP). It is hypothesised that GTP might activate lactic acid bacteria and enhance silage fermentation. This study was conducted to evaluate the potential of GTW and GTP as silage …

IGC Proceedings (1997-2023)
Ensilage of herbaceous biomass can be enhanced by applying pre-selected fermentative bacteria, however insufficient is known about the population dynamics of such starter cultures under a range of ensiling conditions. Classical methods for species-specific quantification of bacteria are labour intensive. An alternative approach is the detection of bacteria based on molecular markers for species-specific regions within their genomic DNA (e.g. the 16S rDNA sequence). In this study, a quantitative marker assay using the real-time PCR technique (Q-PCR) is described for Lactobacillus plantarum, a bacterium often used for silage starter cultures.
Improving The Aerobic Stability Of Whole-Crop Cereal Silages, I. Filya, E. Sucu, A. Karabulut
Improving The Aerobic Stability Of Whole-Crop Cereal Silages, I. Filya, E. Sucu, A. Karabulut
IGC Proceedings (1997-2023)
Whole-crop cereal silages, such as wheat, sorghum, and maize are susceptible to aerobic deterioration, especially in warm climates. This is because aerobic yeasts are the most active at 20-30°C (Ashbell et al., 2002). Therefore, it is very important to find suitable additives that inhibit fungi and protect the silage upon aerobic exposure. Propionibacterium acidipropionici is propionic acid bacteria (PAB), which produce propionic and acetic acid in silage. Results with these micro-organisms in laboratory studies were promising with regard to aerobic stability. The purpose of the present work was to study the effects of PAB, lactic acid bacteria (LAB) and …
