- The accuracy of fodder analysis depends on the sample you send to the laboratory. It is critical that the sample represents the average composition of the "lot" of fodder sampled, otherwise the laboratory tests will not be useful. A "lot" is defined as hay or silage taken from the same cutting, at the same stage of maturity, the same species (pure or mixed) and variety, the same paddock, and harvested within 48 hours. Other factors influencing the definition of a "lot" include rain damage, weed content, soil type, treatment after cutting and storage effects. A "lot" of baled hay or cubes should not exceed 200 tonnes.
- This experiment was designed to compare different varieties and harvest time of sorghum hydroponic fodder based on nutrient content and biomass production. Experimental design for fodder productivity was completely randomized design with 2 x 3 factorial, i.e., sorghum varieties (KD 4 and Super-1) and time of harvesting the sorghum hydroponic fodder (8, 12 and 16 d). Total biomass and DM production, were affected significantly (p < 0.05) on harvest time. Total biomass and nutrient content were increased in longer harvest time. The nutrient content were increased with decreasing total value of DM. Super-1 varieties harvested at 12 d had a good quality of fodder and it can be alternative of technology providing quality forage and land saving with a short time planting period and continuous production.
- A fact sheet on sprouted barley.
- This Spring we are exploring an alternative to how we are feeding our herd (and chickens too!) The idea comes from the notion of fresh sprouts as a “superfood”; if eating sprouts are super healthy for humans, then wouldn’t that also be true for animals? As we are finding out, it sure is!
- Barley grain was sprouted in a still hydroponic growing chamber for 6, 7 and 8 day periods and sampled for chemical analyses, protein fractions,in vitro digestion and metabolisable energy (ME) determination. Productivity measured on the basis of the input-output balance of barley grain and GF yield. Results showed that CP, Ash, EE, NDF, ADF and water soluble carbohydrate (WSC) were increased whereas OM and non fiber carbohydrate (NFC) decreased (p < 0.05) in the GF when compared with the original grain. As the growing period extended from day 6 to day 8, the CP, Ash, EE, NDF and ADF were increased but NFC and WSC reduced (p < 0.05). The non protein nitrogen was increased but true protein decreased (p < 0.05) in GF in comparison to barley grain, however no differences was shown among the growing periods for protein fractions. The potential (b) and rate (c) of in vitro gas production shown a decreasing trend (p < 0.05) by sprouting the barley grain up to 8 days. The amount of OM and ME of GF, obtained per kg of cultivated barley grain, were lower than those of the original grain.
