Abstract
The compound feed for improving reproductive performance of parent fishes of trachinotus ovatus comprises, by mass, 0.8-1.2% of DHA algal oil, 0.8-1% of ARA algal oil, 0.2-0.3% of lysine, 0.7-0.9% of arginine and 0.5-0.8% of vitamin premix, wherein the vitamin premix contains 15mg/kg of fenugreek saponin powder. The parent fishes of the trachinotus ovatus fed by the feed have excellent growth and reproduction performance, the average sexual maturation coefficient reaches 16.05 percent, and the average fertility rate, the fertilized egg hatchability and the hatched larva survival rate are 66.25 percent, 95.3 percent and 90.4 percent respectively.
Description
Technical Field
The invention relates to the technical field of aquatic product compound feeds, in particular to a compound feed for improving reproductive performance of trachinotus ovatus parent fish and a preparation method thereof.
Background
Oval pompano is a warm water type middle and upper layer migratory fish, and has fine meat quality, delicious taste and rich nutrition. Under the condition of artificial feeding, an individual with the body length of 2 cm can take the minced fish and shrimp meat paste, and young and adult fish can be fed with fish and shrimp pieces and artificially matched with granular bait. The trachinotus ovatus is fed with fish in daytime, so that the bait is fed manually in the morning or before the evening, or fed by an automatic feeder. Under normal water conditions, the feeding intensity of trachinotus ovatus varies with the water temperature. Generally, when the water temperature is below 16 ℃, the trachinotus ovatus is not taken, a small amount of trachinotus ovatus is taken when the water temperature reaches 16-18 ℃, and the trachinotus ovatus is actively taken when the water temperature is above 22 ℃.
At present, the means for strengthening cultivation of parent fishes of trachinotus ovatus is mainly feeding with fresh ice and commercial feed. The biggest problem of feeding trachinotus ovatus with the iced fish is that the water body is easy to damage, and simultaneously, the disease caused by the iced fish carrying pathogenic bacteria is difficult to stop. The existing artificial compound feed cannot completely meet the nutritional requirement and the breeding requirement of parent fishes due to the delay of the nutrition research on the parent fishes in the breeding period, and simultaneously, the health and the rapid development requirement of offspring are hardly considered. At present, the development of parent fish compound feed for other fishes is less, and the direct action on the gonads of the parent fishes is less and more profound mainly by enhancing the nutrition level or using certain additives.
Disclosure of Invention
The invention aims to provide a compound feed for improving the reproductive performance of trachinotus ovatus parent fish.
The invention also aims to provide a preparation method of the compound feed.
The purpose of the invention is realized by the following technical scheme:
a compound feed for improving reproductive performance of trachinotus ovatus parent fish is characterized in that: the feed comprises, by mass, 0.8-1.2% of DHA algal oil, 0.8-1% of ARA algal oil, 0.2-0.3% of lysine, 0.7-0.9% of arginine and 0.5-0.8% of vitamin premix.
Further, the vitamin premix contains 15mg/kg of fenugreek saponin powder.
According to the invention, with attention to the propagation characteristics, on the basis of meeting the requirement of the parent fish on nutrition by intensive cultivation by a nutrition level higher than that required by conventional commercial fish cultivation, DHA algae oil, ARA algae oil, lysine, arginine and trigonella foenum-graecum saponin powder added in the premix are mutually cooperated and directly acted on the gonads of the parent fish, so that the parent fish is promoted to be healthy and rapidly developed, the sperm quality of male parent fish is improved, and the sperm activity is improved; the egg number and egg yolk deposition efficiency of female parent fish are improved, and the survival rate of fertilized eggs and hatched larval fish is improved.
Furthermore, the compound feed also comprises 20-23% of flour, 4-7% of soybean meal, 4-6% of corn protein powder, 42-44% of imported fish meal, 1.5-2.5% of fish soluble paste, 1.5-2% of Xin peptide protein, 4-6% of imported chicken meal, 4-6% of blood cell protein powder, 1-2% of calcium dihydrogen phosphate, 0.8-1.5% of zeolite powder, 2-4% of soybean oil, 0.5-0.8% of choline chloride and 0.4-0.6% of mineral premix.
In the mineral premix, each kilogram of the premix contains 100mg of iron, 20mg of magnesium, 10mg of manganese, 30mg of zinc, 15mg of copper and 15mg of selenium.
Preferably, the compound feed comprises, by mass, 22% of flour, 6% of soybean meal, 5% of corn gluten meal, 43.1% of imported fish meal, 2% of fish soluble paste, 2% of Xin peptide protein, 5% of imported chicken meal, 5% of blood cell protein powder, 1.5% of calcium dihydrogen phosphate, 1% of zeolite powder, 3% of soybean oil, 0.5% of choline chloride, 0.5% of mineral premix, 1% of DHA algae oil, 1% of ARA algae oil, 0.2% of lysine, 0.7% of arginine and 0.5% of vitamin premix.
The preparation method of the compound feed is characterized by comprising the following steps: weighing bean pulp, corn gluten meal, imported fish meal, Xin peptide protein, imported chicken powder and blood cell protein powder, mixing, carrying out primary superfine grinding, sieving by a 60-mesh sieve to obtain primary compound feed, mixing flour, monocalcium phosphate, zeolite powder, arginine, choline chloride, mineral substances, vitamins and the primary compound feed to obtain a mixture, sequentially spraying fish dissolving pulp, soybean oil, ARA algae oil and DHA algae oil into the mixture, uniformly mixing, carrying out secondary superfine grinding to obtain premix feed, and finally carrying out steam conditioning and granulation.
Further, the steam modulation is to perform conditioning treatment on the premixed feed subjected to secondary superfine grinding for 3-5 min at the steam pressure of 0.2-0.4 MPa and the modulation temperature of 90-95 ℃, wherein the moisture content of the conditioned feed is 15-18%.
