Definitions

  • the invention relates to a method and an arrangement for animal feeding management, in particular for feed management of animals based on their body condition.
  • Successful impregnation of female animals is one of the main factors and challenges of running a profitable animal herd, such as a dairy herd. It is, therefore, very important for an animal keeper to detect when an animal is in heat, in order to inseminate the animal at the correct time. Further, a healthy animal is more prone to successful insemination, e.g. Artificial Insemination, Al, than a less healthy one. Therefore, it is also important to promote animal health to increase successful impregnation.
  • Body Condition There are different methods for evaluating various health conditions of an animal. For example: visual inspection, weighing, and/or observation of milk yield, milk quality, feed consumption, activity, etc., could be used to collect indications of the animal health.
  • One method for evaluating body energy resources of an animal is so-called Body Condition
  • BCS is a method of evaluating fatness or thinness in animals, such as cattle, according to a scale (range of values), e.g. a five-point scale.
  • a scale range of values
  • a score of one, "1” denotes a very thin animal
  • a score of five, "5" denotes an excessively fat, or obese, animal.
  • a BCS estimate for an animal should reflect the body energy resources, or body condition, of the animal.
  • the scale (range of values) used for the BCS differs e.g. between countries, and there are at least a five (5), an eight (8) and a ten (10) point scale.
  • Body condition scoring is often considered better for monitoring body energy reserves than body weight. Body weight can change due to changes in e.g. body fat, gut size, udder size, pregnancy status, and intake of food and water. Body condition scoring, however, does not vary in the same manner with changes in these parameters. Traditionally, BCS has been performed based on visual and tactile inspection by professional scorers or skilled farmers, but use of 3D imaging technology has now made it possible to derive BCS estimates in an automatic manner.
  • BCS values some studies have resulted in certain recommendations of desired, or "ideal”, BCS values in different phases of an animal's life, such as e.g. during a period of lactation.
  • Figure 1 show an example of recommended BCS values for certain types of cows during a lactation cycle.
  • An object of the invention is to improve the fertility of female animals for which BCS can be used, in a more efficient and successful manner than in the prior art.
  • a method and an arrangement are provided for achieving this object.
  • Providing adequate feed to animals is an important aspect of animal management. It is identified that a certain time after parturition, when the animal regains its energy balance, is an important time for the fertility of an animal. For example, it is only after this time that the animal again may become susceptible to conception. It is also identified that starting to provide a feed composition which is composed for stimulating ovum quality and successful implantation of an embryo at or around this time promotes high conception rates.
  • An object of embodiments of the invention is to promote animal fertility by enabling precision feeding and thereby make the animal more susceptible to conception, e.g. by artificial insemination.
  • a method for animal feeding management comprises obtaining a plurality (time series) of BCS estimates for an animal from a BCS device operable to automatically derive a BCS estimate of an animal.
  • the plurality of BCS estimates represent different points in time during a post-parturition period of the animal.
  • the method further comprises determining that the animal has reached Nadir based on the obtained plurality of BCS estimated, and in response, triggering a change of feed composition for the animal.
  • a control unit for animal feeding management is provided. The control unit is configured to obtain a plurality of BCS estimates (time series) for an animal from a BCS device operable to automatically derive a BCS estimate of an animal.
  • the plurality of BCS estimates represent different points in time during a post-parturition period of the animal.
  • the control unit is further configured to determine, based on the obtained plurality of BCS estimates, that the animal has reached nadir; and to, in response, trigger a change of feed composition for the animal.
  • an arrangement for feeding management of an animal comprises a control unit according to the second aspect, and an identification unit configured to provide a unique identification of the animal.
  • arrangement further comprises a BCS device, configured to automatically derive a BSC estimate of the animal, and to provide the BCS estimate to the control unit.
  • a computer program which comprises instructions which, when executed on at least one processor, cause the at least one processor to carry out the method according to the first aspect.
  • a carrier which contains the computer program according to the fourth aspect.
  • the carrier is one of: an electronic signal, an optical signal, a radio signal, or a computer readable storage medium.
  • FIG. 1 is a diagram illustrating reference BCS values for cows on a five point scale.
  • Figures 2-4 are flow charts illustrating a method for animal feeding management according to exemplifying embodiments.
  • Figures 5a-5c are schematic block diagrams illustrating different implementations of a control unit, CU, according to exemplifying embodiments.
  • Figure 6 shows an arrangement comprising a control unit, an identification unit and a BCS device, according to an exemplifying embodiment.
  • this point or period, Nadir may be anticipated and detected, and the feed composition given to the animal can be changed at the right time with high precision.
  • This is very advantageous and improves the fertility of the animals and thus the number of successful inseminations.
  • such automatic detection of Nadir and control of feed composition can be accomplished in a completely automatic manner, which is an enormous help for an animal keeper, especially for large herds.
  • the feed can be changed from a more so-called glucogenic feed composition, given during the period after parturition, to a more so-called lipogenic feed composition at or around Nadir.
  • glucogenic is meant, very simplified, that the feed composition is composed to stimulate so-called gluconeogenesis, which is a metabolic pathway that results in the generation of glucose from certain non-carbohydrate carbon substrates. It has been identified that a more glucogenic (than lipogenic) feed composition improves the energy balance and decreases plasma ketone body concentration in dairy cows during early lactation.
  • feed components that may be comprised in a more glucogenic, or "fat mobilizing", feed composition are e.g. starch, corn and propylene glycole.
  • lipogenic is meant, very simplified, that the feed composition is composed to stimulate lipoogenesis, which is a biochemical process by which organisms produce e.g. fatty acids from acetate.
  • feed components that may be comprised in a lipogenic feed composition are dietary fat, and fiber, which is fermented to acetate and butyrate. Diets which are high in fiber and low in starch increase the acetate-to-propionate ratio. Propionate is the major precursor for gluconeogenesis, whereas acetate is a main precursor for de novo lipogenesis.
  • the feed composition could be changed by increasing the lipogenic-to-glucogenic nutrient ratio for the animal at or around Nadir.
  • cows will be used as the exemplifying animal.
  • the invention is, however, also applicable for other types of (non-human) mammals, for which BCS may be used. Examples of such animals are e.g. buffalo, pigs, goats, sheep, camels, horses, etc. Below, animal energy balance and BCS will be described in more detail.
  • the five-point BCS system was developed to measure the relative amount of subcutaneous body fat of animals. Most body condition scoring systems in dairy cattle use the five-point scoring system with quarter point increments. Instructions for a body condition scoring system have been devised to assess the body condition of a dairy cow at any point during the production cycle.
  • the parts typically considered for BCS, at least of dairy cows, are the thoracic and lumbar regions of the vertebral column (chine, loin and rump), spinous processes (loin), tuber sacrale (hooks), tuber ischii (pin bones), and anterior coccygeal vertebrae (tail head). Use of only a single factor may be misleading, while considering all factors together provides an accurate score.
  • Figure 1 illustrates an inter-calving profile of BCS values for a cow. As previously mentioned, the body condition score of a cow may be assumed to decrease from the time of calving to 40-100 days after calving, when she reaches Nadir.
  • the BCS value of a cow at calving is associated with (have implications on, affects) e.g. milk production, reproduction, and health.
  • the actual strength of the association may vary, there is relative consistency in the associations among calving BCS; Nadir BCS, and post-calving BCS change, on milk production; postpartum anestrous; the likelihood of a successful pregnancy and days open; the risk of uterine infection; and the risk of metabolic disorders.
  • the association with BCS is nonlinear.
  • an optimum calving BCS value may be e.g.
  • the body condition, as measured with BCS, of a normal healthy cow fluctuates over time, and especially during periods of lactation, as can be seen in figure 1.
  • a recommended body condition score value for certain breeds may be e.g. 3.25 to 3.75 (on a 5-point scale), or somewhat lower.
  • the cow increases the production of milk until peak milk production is reached. During this period the cow uses its body reserves, (i.e. previously stored energy), to get the energy needed, as food intake will lag behind requirements, at least in the first six to eight weeks of lactation. It is desired to have a loss in the body condition of no more than 0.5 to 0.75 (on a 5-point scale) in early lactation.
  • the body condition score should slowly increase to reach the same recommended value as at calving, i.e. of e.g. 3.25 to 3.75 (on a 5-point scale), at the end of late lactation.
