Small Grain Forage Trial

Spring cereal grains such as oats, barley, triticale and wheat can have the potential to provide high yield and quality feed for livestock. These cool season annuals can provide early season grazing, as well as high quality stored feed. Spring grains are generally planted in mid to late April and can be harvested at various stages of development. In addition, production of high quality forage in the early season can improve the level of beneficial fats (i.e. Omege-3) in the milk. The objective of this project was to evaluate yield and quality of various spring grain species harvested in the vegetative, boot or soft dough stage. The overall goal of this project is to help organic dairy producers reduce their reliance on expensive concentrates through the production of a variety of high quality annual forages. The data presented here is from one replicated research trial in Vermont. Crop performance data from additional tests in different locations, and often over several years, should be compared before you make conclusions. This project was supported through the Organic Valley Farmers Advocating for Organics fund

The goal of this work was to evaluate grazing behavior of lactating Murrah buffalo cows supplemented with cupuassu byproduct containing 16.8, 51.4, 8.3, 83.5 and 3.4% of ether extract (EE), neutral detergent fiber (NDF), crude protein (CP), total digestible nutrients (TDN) and nonfibrous carbohydrate (NFC), respectively. Experimental rations were balanced for reaching levels of 22.0 % of crude protein (CP) and 80.1 % of total digestible nutrient (TDN)

PENGARUH PEMUPUKAN TERHADAP KANDUNGAN FRAKSI SERAT TANAMAN KALIANDRA (Calliandra calothyrsus) FASE VEGETATIF PADA TANAH INCEPTISOL

Penelitian ini bertujuan untuk mengetahui pengaruh pemupukan yang paling efisien terhadap kandungan fraksi serat tanaman kaliandra periode akhir vegetatif pada tanah inceptisol. Penelitian ini dilaksanakan menggunakan metode eksperimen Rancangan Acak Kelompok (RAK) dengan 4 perlakuan dan 3 kelompok, yaitu: A = tanpa pemupukan organik atau anorganik; B = 50% pupuk anorganik {N (25 kg/ha urea) + P (75 kg/ha SP-36) + K (25 kg/ha KCl)} + 50% pupuk organik (1.000 kg pupuk kandang); C = 25% pupuk anorganik {N (12,5 kg/ha urea) + P (37,5 kg/ha SP-36) + K (12,5 kg/ha KCl)} + 75% pupuk organik (1.500 kg pupuk kandang); D = 100% pupuk organik (2.000 kg pupuk kandang). Peubah yang diamati adalah Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), selulosa dan hemiselulosa tanaman kaliandra. Hasil penelitian menunjukkan bahwa perlakuan pemupukan terhadap kandungan fraksi serat tanaman kaliandra pada akhir periode vegetatif (umur 6 bulan) pada tanah inceptisol memberikan pengaruh berbeda tidak nyata (P>0,05) terhadap kandungan Neutral Detergent Fiber (NDF) kaliandra (48,40% sampai 49,20%), Acid Detergent Fiber (ADF) kaliandra (31,62% sampai 32,94%), selulosa (19,18% sampai 19,83%), hemiselulosa (16,26% sampai 16,78). Berdasarkan hasil penelitian dapat disimpulkan bahwa pemupukan pada tanaman belum memperlihatkan pengaruh nyata terhadap peningkatan kandungan fraksi serat Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), selulosa dan hemiselulosa tanaman kaliandra. Kata kunci : Kaliandra, Kandungan fraksi serat, Pupuk organik dan Pupuk anorganik, Tanah inceptiso

Vermont Organic Corn Silage Performance Trial Results

In 2010, the University of Vermont Extension conducted short and long season organic corn silage variety evaluations in cooperation with Vermont Technical College (VTC) and Organic Valley Farmers Advocating for Organics Program (FAFO). The purpose of the program was to provide unbiased performance comparisons of commercially available organic corn varieties. It is important to remember, however, that the data presented are from replicated research trials from only 3 locations in Vermont. Crop performance data from additional tests in different locations and often over several years should be compared before you make conclusions

Summer Annual Variety Trial

Warm season grasses, such as sorghums, sudangrass, crosses, and millets are high-yielding summer annuals that can provide quality forage in the hot summer months, when cool season grasses are not as productive. The addition of summer annuals into a rotation can provide a harvest of high-quality forage for stored feed or grazing. Generally, summer annuals germinate quickly, grow rapidly, are drought resistant, and have high productivity and flexibility in utilization. However, it is important to know the challenges of growing summer annuals, including the high cost of annual establishment, increased risk of stand failure due to variable weather, and the risk of toxic levels of nitrates and prussic acid in sorghum and sudangrass crops. UVM Extension conducted this variety trial to evaluate the yield and quality of warm season annual grasses

Using NDF and ADF to balance diets (1993)

This publication shows how neutral detergent solution can be used to measure neutral detergent fiber (NDF). NDF represents the total plant fiber or cell wall including hemicellulose, cellulose and lignin. This publication also shows how acid detergent solution can be used to measure acid detergent fiber (ADF), which contains cellulose and lignin. Both ADF and NDF data help to more accurately estimate feed intake, energy values and animal performance

Generally, summer annuals germinate quickly, grow rapidly, are drought resistant, and have high productivity and flexibility in utilization.

The effect of protease and in ß-glucanase supplementation on digestibility of protein, fat and fiber barley-soybean meal based diets by weanling pigs

Recent attention has been given to enzymes as gut-active growth promoters able to lead to a partial degradation of endosperm cell walls in feeds, increasing the proportion of the diet digested by the animal. The aim of this work was to determine if feeding- diets supplemented with protease and/or B-glucanase affects fecal digestibility (F.Dig) of dry matter (DM), crude protein (CP), fat (FAT) and neutral detergent fiber (NDF)

Brown Mid-Rib Corn Variety Trial

Brown mid-rib (BMR) corn has a lower lignin content than other silage corn varieties. The lower lignin content increases the fiber digestibility (NDF digestibility) of the corn silage. Increases in NDF digestibility lead to increased in dry matter intake, milk production, milk protein content, and better body condition. Several studies have reported that for every one percentage point increase in NDF digestibility fed to dairy cattle there will be a 0.50 lb per day increase in milk production. Feeding BMR corn silage is a means to increase NDF digestibility and milk production. Since 2010, the University of Vermont Extension Northwest Crops & Soils program has conducted research trials to evaluate BMR corn silage varieties. In 2012, the trial included 10 varieties from three different seed companies. While the information presented can begin to describe the yield and quality performance of these BMR corn varieties in this region, it is important to note that the data represent results from only one season and one location.
