How can you tell whether a dog is really pregnant?
The signs of pregnancy in a female dog appear about one week after mating. Specifically: the vulva of a pregnant female dog will contract rapidly; around the third to fourth week of pregnancy, symptoms such as vomiting and loss of appetite may appear; at 20 to 30 days of pregnancy, the mammary glands of the pregnant dog become prominent, the breasts swell, and the nipples turn peach-pink. In the fourth week after mating, by touching the area of the uterus in the female dog's abdomen with your hand, you can feel embryos about the size of an egg in a pregnant female dog. In addition, at 20 to 30 days after mating, you can ask a veterinarian to take a blood sample for testing or use ultrasound diagnosis and other methods.

Be careful when dosing pigs: determine whether the tube is in the esophagus or the trachea
When a pig falls ill, it often has a reduced appetite or even stops eating, which makes forced manual dosing difficult. So how can this problem be solved? First, hold the sick pig firmly so it stands or lies on its side. Then, use a mouth gag to pry the pig's mouth open, and quickly pass a stomach tube along the tongue, through the base of the tongue, and into the esophagus. Once you have confirmed the stomach tube is in the correct position, inject the pre-dissolved medicine, and after dosing, pump a small amount of air into the tube to empty any remaining medicine from it. Finally, quickly withdraw the stomach tube. Pay special attention

Why can't sweet potatoes and potatoes be stored together?
Sweet potatoes cannot be stored together with potatoes for two reasons: the required temperature during cellar storage differs. Sweet potatoes are a heat-loving crop, planted in the high-temperature summer and early autumn, and the optimal temperature during cellar storage is 10°C~15°C. If the temperature is too low, they suffer chilling injury, and in severe cases develop "hard core" rot. Potatoes are a cold-loving crop, planted in the low-temperature early spring and late autumn, and the optimal temperature during cellar storage is 1°C~5°C. If the temperature is too high, they sprout, turn green, become toxic and are unfit to eat. The ventilation and light requirements during cellar storage differ. Sweet potatoes are stored as tuberous roots, and during winter storage their respiration is weak and their oxygen requirement is very small; they can safely overwinter under dark, unventilated, low-oxygen conditions. Potatoes are different: they are stored as tubers, and during winter storage they not only need a certain amount of scattered light but also must have sufficient oxygen. If oxygen is lacking, potatoes are forced to carry out anaerobic respiration, and because of alcohol poisoning the tubers "sweat", leading to rot. Therefore, winter storage requires good ventilation and a moderate degree of light transmission.

What are the common diseases of clownfish? Learn to tell by eye whether they are sick
1. The fish stays in the bottom corner of the aquarium and refuses to eat at all; this may be shock caused by a rise in NO2 leading to deteriorating water quality, or by trauma, or an ongoing case of white spot disease. 2. The fish keeps rubbing its body against the aquarium glass or the decorative stones inside; possible diseases: white spot disease, parasites, etc. 3. Small white spots as numerous as pinpricks appear on the body and fins and gradually spread; this may be "cauliflower disease." 4. The caudal fin looks as if it is about to fall off; this may be fin rot or caudal fin disease. 5. Breathing

How to Cleverly Identify Whether Fish Have Eaten Their Fill
1. Pay close attention to how long the fish take to eat at the feeding tray or feeding ground. If, after a certain amount of feed is put in (the normal feeding amount), the fish finish the feed in less than 2 hours, it means the feed is insufficient and some fish have not eaten or have not eaten their fill, so an appropriate amount should be added. If the feeding amount per ten-day period is fixed and the daily feeding amount within the period is the same, but by the end of the period the feed put in is finished by the fish in less than 2 hours, it means the fish have gained weight and the feed amount should be increased. When feeding compound pellet feed, if the feed has already been finished but the school of fish is still swimming rapidly on the surface layer searching for food and is unwilling to sink into the "second layer of water," it indicates the fish have not eaten their fill. If the school of fish has already dispersed from the feeding tray or feeding ground and there is still leftover bait, the fish have eaten more than their fill, and the feeding amount can be appropriately reduced next time.

How can snow jujubes be turned into gold? Let's all put our heads together
Panchi Township is a mountainous area, and wild sour jujubes grow all over the hillsides. In recent years, the farmers have believed in scientific farming, invited professors from the Chinese Academy of Sciences, and successfully grafted and cultivated pear jujubes and snow jujubes, crisp, sweet and fragrant. The farmers are all accustomed to packing every 10 kg of jujubes into a cardboard box for sale, and they did make some money. But before long, Wang Chunhua, director of the Panchi Industrial and Commercial Office, discovered that when consumers bought those jujubes, they repeatedly said that each box was too big and too heavy, that a family could not eat so many at once, and that they were inconvenient to store. So he suggested to the growers that they change the 10 kg large box into 2

Can Turtles and Fish Be Kept Together? A Few Things to Know Before You Start
Turtles and fish can be kept together. For mixed turtle-fish culture, the stocking ratio is as follows: per 0.07 hectares, stock 300 silver carp (specification 20-25 g each), 80 bighead carp (specification about 25 g each), 120 grass carp (specification 50-125 g each), 80 common carp (specification about 25 g each), and 80 blunt snout bream (specification 12.5-25 g each). Then stock about 1,200 turtles aged 3-6 years. Fish fingerlings are best stocked before the Spring Festival, while turtles are best stocked after the beginning of spring, when the water temperature has stabilized above 15

Can Keeping Chickens, Ducks, and Geese Together with Pigs Lead to Highly Pathogenic Avian Influenza?
Poultry should not be kept together with pigs, because influenza viruses from poultry can infect pigs, and human influenza viruses can also infect pigs. Since influenza viruses have 8 different nucleic acid segments, when these two different virus particles infect a single cell together, their nucleic acid segments undergo reassortment and rearrangement to produce new types of influenza virus particles. These new influenza virus particles can often cause major epidemics in humans, resulting in great harm. In addition, chickens should not be kept together with waterfowl such as ducks and geese, because
