More or less flexibility Cost of the feeder cattle and feeds costs accounts for ___ of a feedlot's budget a)93% b)94% c)95% d)96% - Answer-c)95% Purchase price of feeder cattle accounts for ___ of feedlots costs. a)75% b)65% c) 76% d)66% - Answer-d)66% What is conformation and why is it important? - Answer-It's the appearance of the live animal. Proper conformation leads to max amount of high value cuts of beef. What are the high-value cuts? - Answer-Loin Rib Round Rump What are the l0w-value cuts? - Answer-Chuck Brisket Flank Plate Shank What is haylage (Grass Silage)? - Answer-Young respiring plants are cut, partially wilted (to 45-60% moisture, pH 7.0) and placed in a silo or wrapped with plastic to eliminate exposure to oxygen. What is the respiratory phase of haylage? - Answer-First one. Oxygen that is trapped in storage is rapidly consumed by aerobic bacteria. What is the fermentation phase of haylage? - Answer-Second one. Anaerobic bacteria grow, multiply, and convert the plant sugars into organic acids — mainly lactic and acetic = reduce the pH to 4 to 5. What happens after the fermentation phase? - Answer-Accumulation of acid stops bacterial growth & fermentation. Haylage will be preserved (retain moisture and nutrient content) at a stable pH with no bacterial growth, providing there is no exposure to air. [Low pH (<4.5) inhibits multiplication of Clostridium.] If a bag become punctured, then the haylage will become spoiled in the areas exposed to oxygen... growth of yeast, mold, aerobic bacteria, +/- anaerobes and secondary fermentation. True or False - Answer-True. What are large round bales? - Answer-(4'x5') often don't have sufficient water-soluble carbohydrates for adequate lactic acid fermentation to achieve a stable pH. Why are horses and haylage at war? - Answer-Horse are the most sensitive of domesticated anilas to botulism. Cl botulism is a spore-forming, anaerobic in soil, in decaying animal carcasses and less often in decaying plant material. Produces toxins. Feed Costs accounts for ___ of feedlots expenses. a) 1/3 b)2/3 c)1/4 d)1/2 - Answer-a) 1/3 Whats the nonfeed (or yardage) costs? - Answer-"Cost per head per day" Ex.
