Description

TECHNICAL FIELD

[0001] The present application relates to the field of calf feeding, in particular, to a method and device for precise feeding of liquid milk and concentrate to calves. BACKGROUND

[0002] The healthy growth and development of calves is the key foundation for determining the final milk production performance of dairy cows and the economic benefits of breeding. Scientific early nutrition management not only ensures the health of calves, but also significantly improves their reproductive efficiency, milk yield and lifetime value as adults, which plays a crucial role in the sustainable development and quality improvement of the dairy industry.

[0003] Currently, in large-scale dairy farms, the feeding management of calves generally faces the following technical bottlenecks:

[0004] Insufficient feeding precision, individual differences ignored: The traditional group feeding mode or simple timing and quantity scheme cannot accurately adjust the nutrition according to the individual differences such as birth weight, real-time body weight, and body condition of each calf. This easily leads to some calves having excess nutrition while others have insufficient nutrition, affecting the uniformity of the herd and failing to achieve precise cultivation of "one strategy for one calf".

[0005] Decision-making relies on manual labor and lacks scientific data support: The adjustment of feeding amount and the judgment of key weaning time highly depend on the personal experience of the feeders, which is highly subjective and inconsistent. The lack of continuous and automatic collection and analysis of calf growth data (such as daily weight gain and body size changes) and feeding data makes it difficult to develop and implement dynamic and optimized scientific feeding strategies.

[0006] Low management efficiency and high labor cost: Daily weighing, body size measurement, and feeding record keeping require a lot of manpower, and the data recording is prone to errors and difficult to analyze and feedback in a timely manner. At the same time, the automatic degree of liquid milk brewing, heating, and feeding trough cleaning is low, and the labor intensity is high.

[0007] There are blind spots in health and hygiene monitoring: The storage temperature and duration of liquid milk (especially milk powder liquid) are not easy to monitor, and the feeding container may breed bacteria if not cleaned in time. At the same time, it is difficult to detect and warn early the growth and development status of calves (such as growth retardation), which may miss the best intervention period.

[0008] Although there are some automatic feeding devices in the prior art, their functions are mostly limited to basic timed and quantitative feeding, and they fail to form an efficient closed-loop control system of calf identity recognition, growth monitoring, data intelligent analysis and feeding execution, and thus cannot fundamentally realize truly individualized precision feeding and intelligent management. Therefore, developing an intelligent calf feeding system capable of integrating automatic feeding, precision monitoring, data-driven decision-making and early warning functions has become a technical problem to be solved in the field, and thus a method and device for precision feeding of liquid milk and concentrate for calves are provided.

[0042] The present application constructs a full-process automatic closed-loop control from "data perception (monitoring space) → intelligent decision → precise execution (feeding space)". The traditional mode relying on manual experience is completely changed, the key decisions such as feeding amount adjustment and weaning time judgment are based on objective and continuous growth data, the scientificity and consistency of management are greatly improved, and the labor intensity and labor cost are significantly reduced.

[0043] Through the early warning module, various abnormal conditions can be warned, such as deviation of growth indicators, abnormal feed intake, abnormal equipment state, etc. This enables the management personnel to discover potential health problems in time and intervene quickly, changes passive treatment to active prevention, and effectively improves the health level and survival rate of calves.

[0044] The system can automatically monitor the concentrate feed intake of the calf, and combine the body weight and body condition data, the analysis and decision module intelligently judges the weaning time according to the preset logic (such as continuous feeding up to standard), and prompts the administrator through the early warning module, avoiding the stress and growth retardation caused by premature or late weaning of the calf, and ensuring the smooth and scientific weaning process.

[0045] The first cleaning unit and the second cleaning unit are controlled by the automatic maintenance unit, which can automatically clean the milk storage barrel and the feeding trough after each feeding or at regular intervals, avoiding cross infection of the calves; at the same time, the heating unit can ensure the constant temperature of the milk, greatly reducing the risk of diseases such as diarrhea of the calves caused by hygiene problems, and improving the animal welfare.
