The invention discloses a sheep feed-weight ratio measuring system and method. The system comprises a trough assembly, a trough weighing assembly, a single limiting fence, a weighing table, an identity recognition unit and a data processor. The trough weighing assembly is arranged at the bottom of the trough body and used for detecting the weight of the trough body and foodstuff; the single body limiting fences are communicated with the trough assembly and are configured to allow only one sheep to naturally stand and enter each time; the weighing platform is arranged below the single body limiting fences and used for detecting the weight of the sheep; the identity recognition unit is arranged at the entrance of the limiting fence and used for recognizing sheep identities and obtaining individual numbers; and the data processor is in communication connection with the components and is used for receiving individual numbers, feed intake and weight data and calculating and outputting a feed-to-weight ratio. The cover plate of the trough assembly is arranged on the trough body in an openable and closable mode through the opening and closing controller, the situation that the feed is exposed in air to be damped and deteriorated at idle time is effectively avoided, and the accuracy of feed intake detection data is guaranteed. According to the method, automatic measurement of the feed-to-weight ratio is realized by metering the individual feed intake and weight gain.

The invention provides a molecular marker site related to an initial life heavy character on a Tan sheep chromosome 2, wherein the molecular marker site is SNPs mutation on the Tan sheep chromosome 2. By optimizing the dominant alleles of the markers, the frequency of the dominant alleles can be increased generation by generation, the primary living weight character of the Tan sheep is improved, and the genetic improvement process of the Tan sheep is accelerated, so that the economic benefit of Tan sheep breeding is effectively improved.

The application discloses an intelligent device for automatically measuring and collecting live weight before pig slaughtering and carcass weight after pig slaughtering, which comprises a work station one and a work station two. The work station one comprises a visual acquisition station, a weighing table is arranged below the visual acquisition station, and an identification station one is arranged at the side end of the visual acquisition station. The work station two comprises a conveying rail, an identification station two is arranged at the top of the conveying rail, a weighing rail is arranged at the side of the conveying rail, and an anti-shaking stabilizing assembly is arranged below the weighing rail. The intelligent device for automatically measuring and collecting live weight before pig slaughtering and carcass weight after pig slaughtering realizes automatic association of live weight before slaughtering and carcass weight after slaughtering. Meanwhile, a laser sensor is used to collect the shaking characteristics of the carcass, original weight signals are filtered according to the shaking data, and the dynamic weighing precision of the carcass is improved. In addition, the weighing table adopts an open channel design, and the weighing rail adopts a non-contact laser measurement, so that the production line can continuously flow.

The application provides a method for constructing an acute stress animal model. The method comprises the following steps: (1) on the first day to the next day, making the mice experience overnight illumination; (2) on the second day, making the mice experience a cold environment; (3) on the third day, making the mice experience underwater trauma; and (4) on the fourth day, making the mice experience electric shock. The acute stress animal model constructed by the application can stably induce various behavioral changes such as anxiety, fear, depression and enhanced startle reflex, and is accompanied by physiological index changes such as HPA axis activation, body weight reduction and food intake reduction, so that the multi-dimensional phenotype characteristics after acute stress can be more comprehensively reflected. The acute stress animal model constructed by the application is significantly superior to the traditional model in terms of the degree of coincidence with human complex trauma, the coverage range of symptoms and the stability of phenotype, and the expected goal of constructing a composite acute stress model is better achieved.

A system for monitoring livestock of small ruminants comprises: (a) a physically limited receptacle configured for singly accessible by the small ruminants; (b) a drinking trough configured for metering water consumed by an animal; (c) a weighbridge configured for weighing the animal; (d) an IR animal presence sensor; (e) an RFID identification reader; and (f) a control unit. The drinking trough is cooperatively arranged with the weighbridge such that the small ruminant during drinking from the drinking trough stand on the weighbridge. The IR animal presence sensor and RFID identification reader are disposed in proximity of the drinking trough. The control unit is configured for attributing water consumption readings measured by the water meter and live weight readings measured by the weighbridge of the small ruminant identified by the RFID identification reader within a time period of presence detected by the IR animal presence sensor.
