A self-cleaning litter device for animals that extracts waste from litter material contained in a substantially circular chamber. Sifting of the litter is produced by a rotational motion between a rake and the chamber and may be performed by rotating the rake or the chamber. Solid waste is pushed outwards, towards the outer perimeter of the chamber, for removal. A device is provided to prevent the solid waste from smearing against the side wall of the chamber before being removed. A waste receptacle, with a trapdoor to suppress odors, operates independently of the raking device. The rake may be comprised of helically-shaped tines to reduce drag in the litter. Embodiments are described for indoor and outdoor use; and for clumping and nonabsorbent litter.

A litter collection device for sifting animal waste using an improved sifting method is disclosed. The present invention provides a device comprising a device base and a chamber. The device base comprises a receptacle. The chamber located on the device base is filled with a litter material and receives the animal waste. The chamber is rotatable about an axis of rotation and further comprises a chamber opening and a partition. The chamber opening is operable as an ingress and an egress for the animal to deposit the animal waste, and is also operable as a waste opening for dumping the animal waste to the receptacle. The partition comprises screen sections and non-opening sections. The chamber is rotated such that the litter material passes through the screen sections and enters a trough, and the animal waste is kept out of the trough and dropped to the receptacle by the gravitational force.

The invention provides a composition suitable for use as an animal litter comprising a first component having a density less than that of liquid and a second component having a density of at least 5 lb/ft³ (80 mg/cm³) greater than the first component. The invention is based upon the discovery that adding liquid such as urine to a composition having two components with significant differences in density, one of which is less than the density of the liquid, will result in the component with the lesser density floating to the top of the liquid while the component with the greater density will segregate below the component with the lesser density.

An improved automated litter box system which provides increased storage capacity of a waste receptacle which receives animal waste and clumped litter. The increased capacity of the waste receptacle is achieved by elevating the automated litter box system with an elevating apparatus so that a replacement waste receptacle of larger volume can replace the waste receptacle of the litter box system. The invention provides improved automated litter box systems which incorporate such a large volume waste receptacle as a component thereof. The elevating apparatus includes an elevated platform on which the lifter box system is placed. A ramp is provided to provide animal access to the system placed on the elevated platform.

The invention discloses sheep liver feed capable of improving a reproduction rate of a fox/racoon dog fur-bearing animal and its preparation method and use method. The sheep liver feed capable of improving a reproduction rate of a fox/racoon dog fur-bearing animal mainly solves the problem that the existing fur-bearing animal does not have obvious sexuality and has strong hybridization selectivity and thus a reproduction capacity is reduced. The sheep liver feed capable of improving a reproduction rate of a fox/racoon dog fur-bearing animal comprises sheep livers, vitamin E and zinc chelate. The preparation method provided by the invention comprises the following steps of rubbing sheep livers, adding vitamin E and zinc chelate into the rubbed sheep livers, and uniformly stirring. In reproduction, 100 to 110g of the sheep liver feed capable of improving a reproduction rate of a fox/racoon dog fur-bearing animal is applied to a fox/racoon dog fur-bearing animal by two feeding processes every day. The sheep liver feed capable of improving a reproduction rate of a fox/racoon dog fur-bearing animal can improve animal sexuality and promote artificial auxiliary hybridization. Through utilization of the sheep liver feed capable of improving a reproduction rate of a fox/racoon dog fur-bearing animal, a hybridization rate is improved by 14%; a litter size is increased by 0.8; and a segregated feeding-caused death rate is reduced by 1.5%. The sheep liver feed provided by the invention is suitable for feeding of fox/racoon dog fur-bearing animals in reproduction.

The invention belongs to the technical field of medicine for enhancing animal reproduction, and discloses medicine for promoting sows to enhance maternity and a preparation method. The medicine for promoting the sows to enhance the maternity is prepared from 5-15 parts of radix codonopsis, 5-10 parts of rhizoma zingiberis, 5-15 parts of radix glycyrrhizae and 5-15 parts of rhizoma atractylodis macrocephalae according to the mass proportion; a using method comprises the steps that in five days before and after clinical weaning, continuous feeding for every gram of the medicine for the sows to enhance the maternity mixed with 5 kg of body weight sows is conducted for ten days; 2-2.5 kg of the medicine is added to every ton of empty pregnant materials, continuous feeding is conducted until pregnancy is determined, and using is started from three days before weaning. The medicine has the effects of accelerating milk withdrawal, accelerating oestrus, enhancing the maternity, superovulation,and increasing fertilization rate, implantation rate and implantation egg survival rate; and after application of the medicine, one more piglet is produced in each litter.

The invention relates to the field of animal breeding and particularly discloses a method for increasing an in-vivo early-embryo implantation quantity and litter size of a female animal and an application of N-acetylcysteine (NAC) in the aspect of increasing the in-vivo early-embryo implantation quantity and litter size of the female animal. According to the method, taking mice and pigs for example, the intake of the NAC aims at improving uterine environments and improving the developmental potency of early embryos, the quantity of implanted embryos is increased, and thus, the NAC has the capacity for increasing the litter size of female animals; and the NAC belongs to micromolecular compounds, is relatively stable in chemical properties and relatively low in production cost and has a broad application prospect and huge economic benefits.

A method for producing a mixed salt of sodium and aluminum includes providing a solution comprising water, sodium chloride and sulfuric acid, heating the solution to a temperature between 180° F. and 300° F. so that the sodium chloride reacts with the sulfuric acid to form sodium bisulfate and hydrochloric acid and then continue heating until the solution is essentially free of the hydrochloric acid, adding aluminum or an aluminum compound to the solution to form the mixed salt comprising a sodium aluminum sulfate compound and solidifying the mixed salt to form the sodium aluminum sulfate compound.
