Study of using beer residues as animal feedsUpdate: 5/15/2015
Use alcohol residues as feed for ruminant animals
Beer residues as feed for dairy cows
In ruminant animals feeding, grains, beer has been found to be a satisfactory substitute for corn gluten meal in diets for growing heifers (4) (Agris 92-096824) (Lopez-Guisa, 1991 ).
Dry matter of beer residues up to 30% was not found to reduce milk production in dairy cattle (6) (Agris 95-117463) (West, 1994). Food of brewed beer residue has been found to be a satisfactory substitute for corn silage in diets for lactating dairy cows (K) (CAB 981402194) (Munger, 1997). No difference in performance was observed between dried beer residue or wet feeding lactating dairy cows (C) (CAB 770434874) (Porter, 1977). Work results observed brewed beer residues in dairy cattle (11) (Agris 97-064860) (Muenger 1997). There is no performance degradation in performance was observed when either wet or dry beer residue replacing soybean meal in lactating dairy cows (3) (Agris 89-074380) (Hoffman, 1988).
Beer residues as feed for growing cattle
Performance similar to growing beef cattle has been observed (12) (Agris 97-064831) (Morel, 1997). Similar performance when the dregs of beer accounts for 50% of the diet (2) (Agris 89-133992) (Baghdassar, 1986). When brewed beer residues were fed whole can be a problem (J) (CAB 981402193) (Morel, 1997). A typical diet can have the following components, 40% dried citrus pulp, coconut powder 40% and 20% of the dry residue of beer. Cereal beer brewed or moisture can also be fed at levels that can provide the same level of dry matter.
Beer residues as feed for pigs
Soybean protein has been found to be a source of satisfaction finishing pig diets (16) (Agris 85-113680) (Chalermchai Sriratanasak, 1984), (G) (CAB 931460128) (Aletor, 1990).
Beer residues as feed for poultry
Beer residues as feed for chicken
In poultry, beer residue can be used up to 20% with good results. The metabolites of microorganisms in the beer residue seems to improve growth and feed conversion. Similar performance was observed between dry and wet pulp beer for fattening chickens (A) (CAB 731411783) (Wegner, 1973). The dried grains were included brewing at 2-5% of the dry diet without problems can be reduced or broiler feed conversion (13) (1987). Diet with grains of beer 10% did not reduce egg production (14) (Agris 87-118595) (Yeong, 1986), (E) (CAB 761451089) (Jensen, 1976). In broilers include up to 20% of the grains beer not reduce profits or feed conversion during early growth (0-4, 4-8 weeks) and up to 30% did not observed a decrease in performance in broiler chickens (8-12 weeks) (17) (Agris 82-758989) (Deltoro-Lopez, 1981) Other researchers have reported that up to 10% of dry beer can be made food for small birds (0-8 weeks) and up to 30% in older birds (8-18 weeks) growth efficiency (B) (CAB 731413717) (Ademosun, 1973).
Beer residue fed to hens
In laying hens, eating cereal beer up to 30% of dry matter in the diet had no effect, but higher than the performance decrease (18) (Agris 82-758988) (Deltoro-Lopez, 1981).
