This invention relates to the field of agricultural product profit maximization conditioned to a given level of risk mitigation, and more specifically to an apparatus and method for generating optimized living entity and edible tissue growth alternatives and amounts, and generating an inter-variable and temporal relationships between tissue-growth factors of an animal in order to optimize edible tissue output production given inherent enterprise finance, resources, processing, and marketing constraints.
The economic optimization and viability of an enterprise depends on the ability to accurately analyze the relationship between the cost of materials, services, and labor that are input into the enterprise and the return that is achieved on the product that is output by the enterprise. In agribusiness industries that raise animals such as livestock, poultry, marine animals, etc., the inputs include the animal itself, food, shelter, and services. The output, of course, is the marketable tissue components of the processed animal. One of the most critical relationships in optimizing the economic margins of an enterprise is the relationship between the controllable and uncontrollable factors that affect the rate at which the animal and its tissue components grow and the final size of the animal at marketing age. Thus, it is important to have a value-based food chain model that describes the relationship between each of these factors and the rate of growth of a population of animals.
Variables affecting the growth and yield of edible tissue of animals can be divided into genetic and non-genetic categories. Genetic variables are fixed and are reflected by the growth potential of the individual type of animal of interest. It will be appreciated by those skilled in the art that the growth rate of an animal is never higher and only lower than the maximum potential. During its life, an animal seeks to achieve its genetic potential, but fails due to the impediment of non-genetic variables.
Non-genetic variables that are partially controllable by the commercial operator can be divided further into living factors and food factors. Living factors encompass environmental conditions such as temperature, humidity, animal density, ventilation, disease conditions, air quality, etc. Food factors encompass the types and digested amounts of material that are ingested by an animal. In some embodiments, food factors are controlled in a commercial environment through nutrition. The food factor reflects a major portion of the cost during the growth period.
To maximize an enterprise's before tax net margin, many scientists have used models to simulate the growth of various types of animals. (See G. C. Emmans, “The Growth of Turkeys,” 21 Recent Advances in Turkey Science, 135-166 (C. Nixey and T. C. Grey eds. 1989); H. Talpaz et al., “Dynamic Optimization Model for Feeding of Broilers,” Agric. Sys, 121-132 (1986); H. Talpaz et al., “Economic Optimization of a Growth Trajectory for Broilers,” 70 Amer. J. Ag. Econ., 382-390 (1988); P. E. Waibel et al., TURKS Program Agricultural Extension Service (University of Minnesota 1985)). It will be appreciated that the various models represent efforts to take into account the incredibly complex and diverse structure of living entities, as well as the innumerable variables that affect the living entities in their environment.
One model that is used to describe animal growth is the Gompertz curve (B. Gompertz, “On the Nature of the Function Expressive of the Law of Human Mortality, and on a New Mode of Determining the Value of Life Contingencies,” Philos. Trans. Roy. Soc., 513-585 (1825)), which shows the current mass weight as a function of age with known constant parameters. Gompertz curves have been used to describe the growth of poultry only in terms of a singular factor or characteristic such as a genetic characteristic, a living condition, or a food factor (G. C. Emmans, “The Growth of Turkeys,” 21 Recent Advances in Turkey Science, 135-166 (C. Nixey and T. C. Grey eds. 1989); R. M. Gous et al., “A Characterization of the Potential Growth Rate of Six Breeds of Commercial Broiler,” 2 Proceedings of XIX World's Poultry Congress, 20-24 (Amsterdam, The Netherlands, September 1992); N. B. Anthony et al., “Comparison of Growth Curves of Weight Selected Populations of Turkeys, Quail and Chickens,” 70 Poultry Sci., 13-19 (1991)). However, because all the parameters are independent from one to another among all the curves, each Gompertz curve can describe growth in terms of only one set of conditions.
Because of the complexity of a life form, there is a need for a model that describes growth alternatives in terms of a plurality of different conditions. Such a model would permit an accurate economic analysis that allows a commercial operator to simultaneously (non-repetitive) optimize the relationship between the conditions and growth. In turn, the production of living animals would be more easily controlled in order to optimize production and hence maximize economic return.
U.S. Pat. No. 6,076,043 issued to Jinkui Liu on Jun. 13, 2000 with the title “Utilization effectiveness of nutrients in a population” and is incorporated herein in its entirety by reference. U.S. Pat. No. 6,076,043 describes nutrition modeling of animal, poultry and marine animals is a critical component of the respective enterprise optimization and managed environment pollution control. The optimization accuracy depends on the description of utilization efficiency of nutrients in a population of animals. The current invention demonstrates that utilization efficiency of nutrients for meat production in a population should be described based on at least three component parts of nutrient utilization, i.e., maintenance, linear gain, and non-linear gain, instead of one only. Efficiencies for maintenance and linear gain are fixed value(s), but nutrient efficiency for non-linear gain is a result of intra-population variation and efficiency of linear gain.
U.S. Pat. No. 5,668,718 to Liu et al. issued Sep. 16, 1997 with the title “Generating growth alternatives” and is incorporated herein in its entirety by reference. U.S. Pat. No. 5,668,718 describes an apparatus and method for determining when a living animal reaches its optimum rate of growth. This information is then used to calculate the optimal parameters for achieving the maximum Return on Investment (ROI). The computer determines the optimal number of birds for a flock, type and amount of feed, length of time between hatching and sale to food processor, etc. The computer consists of a microprocessor, random access memory, a storage device, a keyboard, a computer screen, a printer, a math co-processor.

Nos. 6,115,692, 6,076,043 and 5,668,718, by further including financial, market-demand, insurance, weather, genetics, and risk-mitigation models and the like to maximize expected profit while operating to limit risk to a chosen level.
One advantage of the present invention is that it is based on the correlation between constant parameters among a multitude of Gompertz curves, each describing the growth of an animal given a predetermined characteristic. Thus, a commercial poultry operator can use the apparatus and method of the present invention to simultaneously optimize growth and yield in a plurality of living and food conditions in order to maximize economic return.
The present invention generally relates to a modeling method and operating a computer that computes the time trajectory that a bird can reach its optimum rate of growth with age. Using this information, the computer can simultaneously determine an appropriate size for a flock of birds, the type and amount of feed that should be fed to the flock, and the age at which a flock should be sold to a food processor, in order to maximize the profits realized by a commercial integrator who raises or subcontracts meat production.
More specifically, the present invention is an apparatus for optimizing the ratio between expenditures and rate of growth for living animals. This apparatus includes processing means for optimizing the ratio between expenditures and the rate of growth for animals, wherein the processing optimum rate of growth according to the equation W=A exp(−exp(−k(t−t*))), where W is the current body weight of the animal, A is the weight of the animal at physical maturity, k is a growth rate factor, t is the current age of the animal, and t* is the age at which the animal has its maximum rate of growth, t* and k being statistically related.
The apparatus also includes memory means for storing data corresponding to information about feed, information about the characteristics of the animals, and information generated by the processing means. The memory means is operationally coupled to the means calculates the optimum rate of growth with age at which the animals can experience their processing means.
The present invention is also in the form of a method for operating the apparatus. The method steps include calculating the time trajectory at which the animal can experience its optimum rate of growth with age according to the equation W=A exp(−exp(−k(t−t*))), where W is the current body weight of the animal, A is the weight of the animal at physical maturity, k is a growth rate factor, t is the current age of the animal, and t* is the age at which the animal has its maximum rate of growth, t* and k being statistically related. The method includes the additional step of storing data corresponding to information about feed, information about the characteristics of the animals, and information generated by the processing means.

For an egg or broiler enterprise, there are multiple input variables that affect profit and loss (the bottom line):
In some embodiments, the present invention correlates equations that describe the multitude of Gompertz curves for various variables that describe the growth of living animals. The results of the correlation allow an animal processor to simultaneously optimize the ratio between expenditures and growth and thus optimize profit margins. In other words, the growth rate of the animal is substantially optimized when the market value of the animal and the cost incurred from raising the animal maximizes the before tax net margin associated with raising the animal or population of animals.
Additionally, the variable can describe both genetic and non-genetic characteristics or factors involved with modeling the growth of the animals or the population of animals. The non-genetic variables are substantially at their optimal values when the net margin is maximized. Some examples of non-genetic characteristics that are described by the non-genetic variable include body weight, population density, nutrient composition of the feed, temperature, and humidity.
In various embodiments, the present invention is used for any type of animal whose growth can be described by a Gompertz curve. However, for purposes of description, the present invention is described in the context of poultry.
“A. Theory”
As described in U.S. Pat. Nos. 6,115,692, 6,076,043 and 5,668,718, a Gompertz curve represents mass as a function of time, and is commonly used to represent the growth of poultry. The Gompertz curve that describes a growth pattern in Laird form is as follows:
W=W0 exp(L/k)(1−exp(−kt)) (1)
The limit of equation (2) as t→∞ is defined as:
lim f(t)=A=W0 exp(L/k) (3)
Equation (4) can be rewritten as:
W=A exp(−B exp(−kt)) (7)
From equation (7), the average daily gain is:
f″(t)=WkB exp(−kt). (8)
The rate at which the average daily gain changes is defined as:
f″(t)=k2BW exp(−kt)(B exp(−kt)−1) (9)
If f ″(t)=0 at the age of maximum gain, then:
0=k2BW exp(−kt*)(B exp(−kt*)−1)B exp(−kt*)=1B=exp(kt*) (10)
where t* is defined as the inflection point, which represents the age at which the maximum daily weight gain is achieved.
The constants t* and k govern the form of growth curve. If equation (10) is substituted into equation (7), then
W=Au (11)
Where u=exp(−exp(−k(t−t*))). Equation (11) shows that current body weight depends on mature weight A and u. Mature weight A is a genetically inherited value. Given fixed genetic conditions, the form of growth trajectory depends on u, i.e., the growth rate factor k and inflection point t*. Therefore, living conditions affect the form of growth trajectory through the parameters t* and k. The growth trajectory represents body weight over age.
Rate factor k and inflection point t* are independent of each other among multiple growth curves even though they are constrained by equation (10) within one curve. Due to the simultaneous impact of living conditions, the two parameters of equation (11) cannot be used to optimize growth by optimizing parameter k and t* independently. Independent optimization of parameter k and/or t* may result in faulty combinations of the two parameters in terms of describing animal growth. Their inter-relationship among different curves has to be established in order to make equation (11) cover multiple curves so that it can be used in an automated computer optimization process, i.e., either make constant k a function of the inflection point t* so that k=f(t*) or make t* a function of k so that t*=f(k).
The equations that are utilized in the program of the present invention are:
W=A exp(−exp(−k(t−f(k)) (12)
For simplicity, Equation (13) will be used for explanation.
When mature weight A and age t is known, only one variable t* is left to predict body weight W in equation (13). The difference between equation (11) and equation (13) is that equation (11) represents only one growth curve and t* is a constant. However, equation (13) represents multiple curves wherein t* is a variable that can be optimized in an optimization process. Therefore, the relationship between k and t* must be defined. This relationship will be in the form of a function k=f(t*).
Experimental growth data for broilers, quails, and turkeys with different genetic and environmental conditions have been obtained from public domain sources and summarized. This information is contained within the program of the present invention and can be used to define the relationship between k and t*.
The body weight for male turkeys of age 0 to 18 weeks (Waibel, P. E., “Pelleting, fat, and protein levels in turkey diets.” 67 Proc. of Maryland Nutrition Conference for Feed Manufactures, March 16-17, (1989)) and female turkeys of age 0 to 18 weeks (Waibel, P. E. et al., “Factorial Study of Protein Level Sequence and Diet Energy/Pelleting on Performance of Large White Hen Turkeys,” 68 reported in Poultry science Association Annual Meeting, University of Wisconsin, Madison. July 24-28 (1989)) are each comprised of 24 different protein sequence treatments. The body weights of each treatment at different ages was independently fitted into equation (11) and the corresponding value fork and t* was calculated. More specifically, constant k and t* were experimentally determined by (See Hurwitz, S. et al., “Estimation of the Energy Needs of Young Broiler Chicks,” Proceedings of the Meeting, Arkansas Nutrition Conference 16-21 (Riverfront Hilton, North Little Rock, Ark., Sep. 10-12, 1991); Talpaz, H. et al., “Dynamic Optimization Model for Feeding of Broilers,” Agaric. Says, 121-132 (1986); Talpaz, H. et al., “Modeling of Dynamics of Accelerated Growth Following Feed Restriction in Chicks,” 36 Agric. Sys., 125-135 (1991); Gous, R. M. et al., “A Characterization of the Potential Growth Rate of Six Breeds of Commercial Broiler,” 2 Proceedings of XIX World's Poultry Congress, 20-24 (Amsterdam, The Netherlands, September 1992); Emmans, G. C., “The Growth of Turkeys,” 21 Recent Advances in Turkey Science, 135-166 (C. Nixey and T. C. Grey eds. 1989); Anthony, N. B. et al., “Comparison of Growth Curves of Weight Selected Populations of Turkeys, Quail and Chickens,” 70 Poultry Sci., 13-19 (1991)) and fitted into equation (11) by mathematical methods that are commonly known in the art. The values of B and L are calculated using equation (10). It is helpful to graph k plotted against t*. In some embodiments, such a graph demonstrates the relationship of k=f(t*) and that the relationship between k and t* is non-linear. In some embodiments, the graph shows that statistical methods demonstrate that k=0.79878t*(−0.83747), where adjusted correlation coefficient r=0.9746.
Equation (13) can be rewritten as
W=A exp(−exp(−(0.79878t*(−0.83747)(t−t*)))). (14)
This equation covers a multitude of growth-curve possibilities and can be used for different types of poultry including turkey, broiler, duck, quail, etc. Given equation (13), constant t* is the only variable to be affected by various living conditions.
Equations (12) and (13) reveal that the rate at which a bird grows depends on only one variable—t* or k. As discussed above, t* is the age at which a bird has its maximum rate of gain and k is a growth-rate factor. The earlier the age, the quicker the bird will grow to the weight at which it may be marketed. The commercial applications of equation (12) or (13) will be very important tools in selecting the most efficiently growing genotype of bird and in genetic breeding. in some embodiments, the present invention has applications related to the production of other types of animals as well as vegetation.
Equation (13) can be utilized in optimizing poultry production because it correlates multiple growth curves, which include a genetic potential growth curve of the type shown in
Change of weight gain=0.71556+7.9902 MDNSITY−57.765 MDNSITY2 where r (correlation coefficient)=0.8846; overall p-value (possibility value)=0.0006; and MDNSITY-body weight density ranged 0.03 to 0.06 meter2/kg 0.67. Similar predictions can be derived by establishing the effect of temperature, humidity, ventilation, etc. on weight gain.
In addition to predicting physical mass of the entire bird, the inflection point t* can be used to predict the growth of each component part of a bird's body. The following is an example for turkeys:
All the above regression equations show that the inflection point t* has a significant effect on dependent variables as indicated by the small number of p-values.
In some embodiments, the report that is generated includes values for the maximum profit that is achieved at each one of a plurality of values of the level of risk taken to achieve the corresponding maximized profit, and then lists the values for each of the variables of flock size, sex, strain, and each of the nutrition variables used to formulate the animal feed, space per animal, ventilation and the like needed to obtain the maximum profit at each of the levels of risk.
