Economies Of Size For Farrow-To-Finish Hog Production In Kansas (1993), Michael R. Langemeier, Ted C. Schroeder Jan 1993

Economies Of Size For Farrow-To-Finish Hog Production In Kansas (1993), Michael R. Langemeier, Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Economies of size measure the impact on average cost of production of increasing the size of operation. Data from 91 farrow-to-finish operations enrolled in the Kansas Farm Management Associations in 1992 were used to empirically estimate economies of size. Results indicate that average total cost and operation size are significantly correlated, and that average total cost declines as operations become larger. Results also indicate a substantial variability in costs of production between producers. In fact, costs of production between producers of a given size vary more than costs of production between operations of different sizes.; Swine Day, Manhattan, KS, November …

Evaluation Of Carcass Merit Pricing By Pork Packers (1993), Ted C. Schroeder Jan 1993

Evaluation Of Carcass Merit Pricing By Pork Packers (1993), Ted C. Schroeder

Kansas Agricultural Experiment Station Research Reports

Live hog prices must reflect end-use value to convey market information from consumers to producers. Precise end-use value is excessively costly to trace for each carcass given current technology. Pricing structures must be based upon carcass merit information that is correlated with end-use value. This study uses pork carcass cut out data from 794 carcasses to estimate hog carcass values based upon carcass characteristics. Carcass values varied by nearly $20/cwt based on quality differences alone. In addition, considerable differences were present in pricing schedules of different pork packers suggesting that hog producers need to shop around when deciding to which …

Two hundred forty weanling pigs (initially 7.2 lb BW and 9 + 1 d of age) were used to compare four dietary sequences of three diets in a 21-d growth trial. Diet A was formulated to contain 1.7% lysine and contained 7.5% spray-dried porcine plasma and 1.75% spray-dried blood meal. Diet B was formulated to contain 1.4% lysine and contained 2.5% spray-dried porcine plasma and 2.5% spray-dried blood meal. Diet C was formulated to contain 1.25 % lysine and contained 2.5% spray-dried blood meal. The four dietary sequences were as follows AAB, AAC, ABB, and ABC, with each letter indicating …

Kansas Agricultural Experiment Station Research Reports

A total of 290 early-weaned pigs (initially 7.6 lb and 10.5 d of age) was used to evaluate various levels of spray-dried porcine plasma. Pigs were assigned to one of five experimental diets with either 5, 7.5, 10, 12.5, or 15% spray-dried porcine plasma replacing dried skim milk. Pigs were fed this diet for the first 14 days postweaning. Common diets were fed from d 14 to 42 postweaning in order to monitor subsequent performance. During the first phase (d 0 to 14 postweaning), linear improvements in average daily gain (ADG) and average daily feed intake (ADFI) occurred as the …
