What do stone turtles eat to grow fast?

There are many kinds of turtles. In fact, tortoises have always represented longevity in our country. With the continuous improvement of people's living standards, turtles have become a very common dish on the dinner table, and many people like to eat them. Because turtle meat is very delicious and nutritious!

What do stone turtles eat to grow fast?

The bait of stone turtles is mainly fish, shrimp, snail clam, animal viscera, etc., supplemented by plant melons, vegetables and grains, and can also use a formula feed with a protein content of 40%. What is the effect of raising stone turtles with different feeds? Zhou Weiguan and Qin Guosen studied this and fed juvenile stone turtles with five different diets (Chinese soft-shelled turtle formula feed, earthworm, silver carp meat, longevity snail and clam meat). The results showed that:

1. The yellow-throated turtle fed with compound feed of Chinese soft-shelled turtle had the fastest weight gain, the highest average daily weight gain and protein efficiency, and the lowest feed gain ratio, followed by earthworm > silver carp meat > Fushou snail meat > and mussel meat. 2. The bait cost of the yellow-throated turtle fed with Fushou snail meat was the lowest, followed by the compound feed of Chinese soft-shelled turtle > earthworm > and mussel meat > silver carp meat. 3. The compound feed of Chinese soft-shelled turtle is a good feed for breeding yellow-throated water turtle, but the sources of Oncomelania hupensis and earthworms are convenient, so it is also a good bait for breeding yellow-throated water turtle.

Seedling breeding of tortoise

The newly hatched juvenile stone tortoise weighs 6.4 to 13 grams, with an average of 9.75 grams. After the yolk is absorbed, the juvenile turtles are put into a formal temporary culture pond. Before stocking, the temporary pond was soaked and disinfected with 1 g / m ³of potassium permanganate with a stocking density of 30 / 50. When stocking, you need to pay attention to let the young turtles climb into the water by themselves, the water level should be shallow, just past the back, in order to narrow the temperature difference, change the water once every morning. Choose egg yolk, red worm, pig liver and so on as opening bait, change to minced fish and formula feed after one week, feed with a little leftover each time, remove the residual bait in time and clean the table. Generally in the morning and evening feeding, twice a day, to achieve four fixed: timing, positioning, quality, quantitative.

Reference amount: 4%-6% of the body weight of juvenile turtles is suitable for fresh animal feed, and 2%-3% of the body weight of juvenile turtles. The water level gradually deepened and finally reached 30cm to 40cm. Disinfection measures are generally sprinkled with raw lime water throughout the pool, once every half a month, with a concentration of 25 g / m ³water. Plant water hyacinth in the juvenile turtle pond to purify water quality and shade the sun. Pay attention to unobstructed intake and drainage, and check whether the spillway is normal in rainy days to prevent young turtles from escaping. Prepare for the overwintering of young turtles or young turtles when winter comes.

How do turtles divide male and female?

1. How to divide a tortoise into a male and a female can be distinguished as long as you know the posture of the turtle's mating. Did you know that the tortoise uses the male upper and lower female position when mating, in order to avoid slipping from the female shell during mating, so the male tortoise's abdominal armour is slightly sunken, just enough to hold the protruding back shell of the female turtle; but the female turtle does not need this structure, so the belly is flat.

2. the judgment of male and female of tortoise is based on the length of its tail (male in length and female in short), or its ventral nail (concave is male and flat is female), or its cloacal foramen (male beyond its dorsal armour, and vice versa). However, the above judgment methods are only accurate in sub-adults or adults, and the above criteria should not be used in the case of larvae.

3. The comparison method can be used to distinguish the larvae, that is, if the responses of all aspects are different, the probability of male and female pairs will be relatively increased. Because the male is naturally active, the two are placed on the ground at the same time, and the first mover is usually male. It can also be compared with the anal shield and the abdominal nail closest to the tail. If the angle of opening is small, it is usually female, and vice versa. In the past, a master taught me a way to identify those who are difficult to judge gender from their appearance for your reference. It is to grab the tortoise's back armor from the top and let the tortoise hang in the air. If its tail is hooked down and forward (as it looks when mating), it is almost certain to be male, but the box turtle is not applicable.

Breeding species of stone tortoise

Meat turtle culture is the main breed: meat turtle culture requires adult weight, so we must choose fast-growing, individual large varieties. Now in the meat turtle culture industry, there are three species of stone turtles for farmers' reference.

1. Vietnamese stone turtles: this species is the stone turtle with the highest edible and medicinal value, the fastest growth rate, and the largest individual (an average of 1500 grams of adult turtles). It can reach an average of 1000 grams in three years under the ecological culture mode. it is the most expensive variety in the meat market. It's just that the price of seeds and seedlings is on the high side, which is suitable for families and courtyard breeding.

2. Fujian stone turtle (Daqingtou): the growth rate of this species is slower, and the individual is smaller (800 grams on average). It can reach 600 grams in three years under the ecological culture mode, and the price in the meat turtle market is slightly lower than that of Vietnamese stone turtles. However, the price of this species of tortoise and seedlings is lower, which is more suitable for breeders with less funds and large sites.

3. Hybrid turtle (also known as Guangxi quasi-water turtle): it is a hybrid between Vietnamese stone tortoise male turtle and Fujian or Anwei stone tortoise female turtle. The growth rate of this species varies, with a few reaching 70000g and most of them 300g / 500g in three years of ecological culture.

In short, no matter which breed is bred, we must choose and determine our own breed according to the use of our own funds, site conditions and sales, so as to maximize economic benefits. Because the price gap of each variety is too large, it is necessary to distinguish what kind of variety it is when buying seeds to avoid loss.

All in all, the market prospect of the tortoise is very good now. With people's pursuit of life getting higher and higher, the demand of the tortoise will only become bigger and bigger, and its development prospects will only become broader and wider. However, there are many kinds of turtles, its breeding costs are also different, investors can choose reasonably according to their own conditions!
