In Vitro Gas Production Technique To Predict Dmd Of Ensiled Forage Ruminant Based Diets, M. Wawrzkiewicz, J. L. Danelón, G. Jaurena

IGC Proceedings (1997-2023)

The in vitro gas production technique was used as a tool to develop an improved prediction model of dry matter digestibility of ensiled forage based diets. Eleven diets were tested through conventional experiments of in vivo dry matter digestibility (DMD). The same diets were evaluated by the in vitro gas production technique using a gas pressure transducer . The parameters of the model y = A - B Q^t Z^√t were calculated with data from the accumulated gas curves, i.e. y=cumulative gas production (ml), Q=e^-b, Z=e^-c, B=e^bT+c√T , being …

IGC Proceedings (1997-2023)

This study determined the effect of surface spoilage in the diet on feed intake and nutrient digestibilities using growing steers fed whole-plant maize silage-based diets. A bunker silo, 0.9 m in depth, and a 2.7 m diameter AgBag were filled with alternating loads of chopped forage. After 90 days, the bunker was sealed with a sheet of polyethylene, and this silage was designated “spoiled”. The silage in the AgBag was designated “normal”. The four diets contained 90% silage and 10% supplement (dry matter basis), and the proportions of silage in the diets were A) 100% normal, B) 75% normal: 25% …

Rejuvenation Of Wild Ber (Zizyphus Species) Through Budding At Farmer’S Field, Ravi Pratap Singh, Satendra Kumar, Rajiv K. Agrawal, Sunil Kumar, M. M. Das, J. B. Singh

IGC Proceedings (1997-2023)

Ber is mainly cultivated for its fresh fruits, which are rich in vitamins C, A and B complex. Due to its nutritional qualities it is called poor man’s apple (Gajbhiya et al., 2003). A large number of wild ber shrubs (Zizyphus mauritiana, Z. rotundifolia and Z. nummularia) were seen growing on the neglected lands, uncultivated lands, roadsides and farm boundaries in Kadesara Kala Village in Lalitpur district of Uttar Pradesh (India). Production potential of this species is very low because of poor upkeep and inferior genetic makeup. But they have extensive root system which can withstand …

Utilisation Of Conserved Forage To Improve Livestock Production On Smallholder Farms In Asia And Africa, Marsetyo, Muhammad Shoaib Tufail, Samuel Mbuku, Mupenzi Mutimura, Xusheng Guo, John Piltz

IGC Proceedings (1997-2023)

Ruminant livestock are essential to the livelihoods of smallholder farmers in many developing countries. Livestock production on these farms is characterised by low milk production, low live weight gain and poor reproductive performance because of poor nutrition. Access to high quality forage has been identified as key to improving livestock health and productivity. Conservation of surplus forage as hay or silage provides the opportunity to ensure livestock have access to high quality forage year-round. This paper reports on forage conservation in select countries in Asia and Africa.

Assessment Of Animal Palatability For Domestic Developed Italian Ryegrass Lolium Multiflorum Lam. In South Korea, Jong-Geun Kim, Hyung-Soo Park, Han-Jong Ko, Jong-Sung Jeong, Meing-Joong Kim

IGC Proceedings (1997-2023)

About 5.6 million tons of forage were consumed in ruminant animals in Korea. But, most of them were supplied in rice straw (2 million ton) and more than one million ton of forage was imported from oversea. As a matter of fact, the self-sufficiency rate of high quality forage was 44 % (2.5 million ton). The research institute had started breeding programs of forage varieties (orchardgrass, Tall fescue and Italian ryegrass), Their remarkable breeding program resulted in release of a synthetic species Italian ryegrass (Lolium multiflorum Lam.) which was more cold-tolerant, much higher yielding than introduced varieties and more …

Relative Losses Of Pioneiro Grass (Pennisetum Purpureum Schumach) Silage With Addition Of Whole Plant Maize Or Maize Grain During Fermentation, Tiago M. Santos, Eduardo R. Scherer, Dayanna Pastal, Diana R. Vivian, Kátia F. Gobbi, Américo F. Garcez Neto

IGC Proceedings (1997-2023)

Among the forages with potential to be ensiled, tropical forages stand out because of their high yield capacity, being able to produce three times more dry matter than for maize under tropical conditions. Although tropical forages are an interesting alternative for ensilage, their high moisture content may impair the fermentation process, reducing the silage quality. The addition of whole plant maize and maize grain to other grass silages can be an efficient way to reduce the losses involved during the process, specially due to the improvement of the fermentative profile of the silages (Stefanie et al. 2000; Anaya-Ortega et …

Characterization And Identification Of Lactic Acid Bacteria Isolated From Silage Prepared In Lao Pdr, Yimin Cai, Huili Pang, Viengsakoun Napasirth

IGC Proceedings (1997-2023)

Silage is now the most common preserved cattle feed in many countries and lactic acid bacteria (LAB) play an important role during silage fermentation process. In order to establish an animal feed production system to cover the shortage of animal feed in the dry season of Lao PDR, silage fermentation technology is needed that has potential application in poor villages. Therefore, the characterization of LAB in various forage crops and their species identification requires further study. In the present study, the characterization of LAB species isolated from forage crops in Lao PDR was examined. In order to determine their taxonomic …

A Lactic Acid Bacterium Isolated From Grass In Native Grassland In Northern China, Qing Zhang, Zhu Yu, Jipeng Tian, Xujiao Li, Yu Wang

IGC Proceedings (1997-2023)

The epiphytic LAB converts sugar into lactic acid during the ensiling process. As a result, the pH is reduced, and the forage is preserved. Therefore, further study of epiphytic LAB species is required, especially the screening of excellent LAB. However, to our knowledge, limited information is available on the epiphytic microflora on grass in native grassland. The present study set out to screen, isolate and identify the LAB from grass silages made in native grass-land in northern China.

Effects Of Lactic Acid Bacteria On The Quality Of Achnatherum Splendens Silage, Yanlin Xue, G. M. Yin, H. P. Zhao, Q. Z. Sun, Zhu Yu, C. S. Bai

IGC Proceedings (1997-2023)

Achnatherum splendens is an important forage for ruminant animals, but it has a high fiber content, and there is little information about the quality of Achnatherum splendens silage. This experiment was undertaken to study the effects of lactic acid bacteria on the quality of Achnatherum splendens (AS) silage.

Improving Lucerne Forage Quality And Utilization By Using Novel Silage Inoculant, Vilma Vrotniakiene, Jonas Jatkauskas

IGC Proceedings (1997-2023)

Lucerne (Medicago sativa L.) is a protein-rich forage that farmers often combine with energy-rich feed sources to dairy cattle. Lucerne ensiles poorly, however, due to low sugar concentration and high buffering capacity. Ensiling is improved by wilting the crop and using an appropriate silage inoculant. The principal goal of inoculants is to improve fermentation quality, to preserve as much of the nutritive value of the crop at harvest as possible for the livestock consuming the resulting silage and to increase production (Meeske et al. 2000, Muck 2012).

The objectives of this study were to determine the effects of …

Silage Inoculants Improves Quality And Aerobic Stability In Grass, Clover-Grass And Lucerne Silage, Jonas Jatkauskas, Vilma Vrotniakiene, Christer Ohlsson, Bente Lund

IGC Proceedings (1997-2023)

The type of silage additive will influence the characteristics of fermentation, dry matter (DM) losses, hygienic quality and aerobic stability of silage. The appropriate use of an additive also depends on the crop to which it is applied. Homofermentative lactic acid bacteria (LAB) strains are selected for rapid growth under under variable temperatures, herbages and dry matter concentrations. The homofermentative LAB are highly competitive and produce largely lactic acid and reduce pH and ammonia-N content compared to untreated silage (Muck 2012). Heterofermentative LAB such as Lactobacillus buchneri reduce the growth of yeast and mould and increase aerobic stability. These effects …
