The Correct Method for Using Feed Additives in Aquaculture

2024-05-16
1. The additive must be used in combination with the feed: Feed additives It must be mixed into the feed before being fed to livestock and poultry; it cannot be fed directly to animals. The quality of the mixing technique directly affects the feeding results. For small-scale farms, manual mixing is suitable. The mixing procedure is as follows: First, pre-mix a small quantity of feed with the additives; then add a certain amount of additional feed and mix thoroughly; finally, add all the remaining feed and mix thoroughly again. Depending on the amount of additives used and the quantity of feed involved, this process can be repeated in several stages. After ensuring thorough mixing, the feed can be served to the animals.
2. Duration of Additive Use: The duration of use for feed additives can be categorized into three types: long-term use, stage-specific use, and short-term use. Long-term-use additives are typically nutritional in nature, such as vitamins, amino acids, and minerals. These additives should be included daily in the animal’s feed throughout its entire life cycle—from early age until market readiness. Stage-specific additives, such as flavoring agents, are used when an animal’s appetite declines. Short-term, emergency-use additives include certain antibiotic alternatives and anthelmintic additives.
3. Poisoning from Additives and Their Antidotes:
Causes of poisoning: 1) Simultaneous use of several additives containing the same ingredient, leading to an excessive intake of that particular ingredient and causing poisoning in animals. 2) Overuse of a single additive when used continuously over an extended period. 3) Improper storage resulting in the degradation and spoilage of the additive. 4) Uneven mixing.
Rescue Measures: 1) Upon detecting signs of poisoning (such as coma, convulsions, moaning, hissing, vomiting, diarrhea, drop in body temperature, irregular heartbeat, or sudden collapse), immediately organize personnel for emergency rescue. Under the guidance of a local veterinarian, cease using the additive immediately. For large animals, induce gastric lavage; simultaneously, conduct examinations and laboratory tests to identify the specific toxic agent. Administer antidotes and neutralizing agents that specifically counteract and neutralize the identified toxic substance, while also promoting bowel movements, urination, sweating, and detoxification.
4. Storage and Preservation of Additives:
1) Keep at low temperature and dry; 2) Do not exceed the shelf life during storage; 3) Add antioxidants and anti-mold agents.
Latest experiment
Broiler Glucose Oxidase Experiment
One-day-old Ross 308 broiler chickens were selected, with a total of 4 chicken houses, each housing 11,000 birds. The birds were randomly divided into a control group and a treatment group, with 2 chicken houses assigned to each group. The control group was fed a commercial diet supplemented with Changle (allicin and oregano phenol) at 100 mL/ton, while the treatment group was fed a commercial diet supplemented with glucose oxidase at 100 U/L. During the trial period, birds had free access to feed and water. The trial lasted for 42 days. The experimental diet consisted of corn, soybean meal, wheat, cottonseed meal, DDGS, peanut meal, duck fat, and premixes, among other ingredients; nutritional parameters are shown in Table 1.
Lactic Acid Bacteria Experiment
Effect of Lactic Acid Bacteria on Broiler Diarrhea: A Raising Experiment Experimental Site: Jiyang Zheng* Animal Husbandry Farm Experiment Period: August 31, 2015 – September 4, 2015 Experimental Subjects: 30-day-old broilers Experimental Design: Control Group: Normal feeding + normal drinking water Experimental Group: Normal feeding + normal drinking water + lactic acid bacteria (liquid)
Piglet Fruit Milk Flavor Experiment
Twenty 28-day-old weaned piglets of the Duroc × Landrace × Large White crossbreed, with similar body weights and in good health, were selected for the trial. They were randomly divided into two treatment groups: a control group and a test group. The control group was fed a basal diet, while the test group was fed a basal diet supplemented with 600 g/t of fruit-milk flavoring. Each group consisted of five replicates, with two piglets per replicate. During the trial period, the pigs had free access to feed and water, and the trial lasted for 28 days.
In this trial, 120 healthy, growing pigs of similar body condition, weighing 80 ± 10 kg, were randomly divided into a control group, an antibiotic group, and an essential oil group. The specific feeding design is shown in Table 1. Each group consisted of 4 replicates, with 10 pigs per replicate. The trial duration was 29 days. The experimental diet was formulated according to the nutritional requirements outlined in NRC (2012). During the trial, pigs had free access to feed and water, and were subjected to routine husbandry management and vaccination protocols. Body weights at the beginning and end of the trial, as well as feed intake, were recorded. At the end of the trial, fresh fecal samples were collected from each pig, placed into sterile 10 ml centrifuge tubes, and stored at -80℃.
Tian Yikang replaces chlortetracycline in the ROSS-308 trial.
This experiment employed a single-factor experimental design. A total of 6,000 Ross-308 broiler chickens, aged 1 day and with roughly similar body weights and good health conditions, were randomly selected and divided into three treatment groups, with five replicates per group, each replicate consisting of 400 chickens. The control group was fed a basal diet based on corn and soybean meal. The experimental group 1, the antibiotic group, had 50 g/t of a 15% chlortetracycline premix added to the basal diet. The experimental group 2, the Tianyikang addition group, had 1,500 g/t of Tianyikang added to the basal diet. The entire experiment lasted for 42 days.
