Limiting rearing of broiler breeder chickens during the rearing period can prevent excessive fat deposition in the chickens and keep them at optimal weight. However, restrictions on feeding will also cause some adverse effects on production, and should be given attention to and resolved.
First, resulting in the deterioration of the home environment Currently, the limited feeding of broiler breeders is usually limited by the amount of feed, that is, by controlling the amount of feed to limit the chicken's intake of protein and energy. In this case, because the chicken's feed intake is under control, about half of the chickens are interested in drinking water. The large amount of drinking water and the water brought out by the neck feathers can easily cause dampness in the bedding. Therefore, we should do a good job of environmental control.
(1) Water restrictions are imposed on the flock, except during the high temperature season, water is supplied 1 hour before feeding on the feeding day, water is stopped 1 hour after the feeding is finished, water is not supplied three times a day, and each time is 1 hour; (2 ) Pay attention to ventilation, diligently drop litter, do not allow excessive accumulation of feces and fermentation; (3) strengthen management, maintain the health of the flock, avoid diarrhea, can add some antibiotic health care drugs in the feed.
2. Initiation of nutritional deficiencies For breeder chickens in the restricted-feeding stage, if the essential ingredients for growth and development of chickens, such as vitamins and minerals, are still added at regular concentrations, feeding will be inevitable due to insufficient feed intake. Over time, it can cause a series of nutritional deficiencies.
The following points must be taken into account when preparing the feed for rearing breeder chickens:
(1) Select high-quality additives;
(2) increase the amount of additives, such as the amount of vitamins can be increased by 30% on a normal basis;
(3) Current use of feeds;
(4) Double the amount of vitamins and minerals when stressed.
Third, the rush to eat the chicken caused by squeezing the bulging limit feeding period breeder tend to show a strong sense of hunger after a long time after eating, especially not feeding day. Feeding should be fast and feed the feed in a short period of time. Try to feed it when it is not light. Supply enough water before feeding. The water should not be far away from the trough. In this way, the occurrence of bloating can be avoided.
Fourth, the use of drugs to reduce the effect of the general use of drugs is based on the normal intake of chickens and other factors from the projection, if the normal feeding concentration of food additives in the feed restriction period, due to reduced intake The decrease in the absorption of antimony drugs has made it impossible for the therapeutic and preventive actions of drugs to play a role, causing certain diseases to occur. Therefore, when using feed-shaking drugs, the use should be increased by 30% on a regular basis, or temporarily changed from feeding to free intake.
Introduction
Holter ECG Monitoring Systems adopt 12-lead system of international standard, which can continuously record ECG waveform for 24-hour and analyze ECG waveform by the PC software. It is applicable for use in medical institution and community.
Analysis Software Function
1.The rate of checking RR wave up to 99.9%, which increased the accuracy of analysis without losing wave.
2.AI histogram function which can directly distinguish various abnormal ECG which can analyze faster.
3. Dynamic Ecg [Channel Correct" function, which can correct mistakenly wearing that makes the analysis more accurate.
4.Lorenz and Demix analysis function, which can analyze more faster, more accurately. Single medical case can be completely analyzed in 10 min, which can reduce the physician`s work.
5.ST can be displayed in many kinds of form, which ensures that analyzing ST- Trends Diagram comprehensively, observing the whole or partial ST variety to analyze the specific area of myocardial ischemia.
6.Atrial fibrillation function can be recognized automatically and can distinguish atrial fibrillation case, give advice and generate analysis report .
7.Unique Cardiac Fatigue Index function, which can judge index of Cardiac Fatigue .High-risk groups can be found and early intervention treatment can be taken by the index, which can effectively judge the heart age and predict SCD (Sudden Cardiac Death).
8. P-wave analysis function, which can check cardiac arrhythmia (such as AVB).
9.According to the requirement of patients, options can be selected freely while printing report, which can save physician `s time
10. ECG can be printed by various forms according to the user`s requirement.
11.Pacemaker analysis function, which can analyze different pacemakers(such as AAI,VVI,DDD).
12.The comprehensive analysis system of stand-alone version with network version ,users can freely select any model.
13.Wire and wireless simultaneously transfer mode ,which reduce complicated performance.
14. Dynamic ECG and static ECG analysis system ,which reduced complex operations.
15. Time Domain and Frequency Domain function on HRV module can reflect the moderation effect of sympathetic and parasympathetic to the heart rate.
16.HRT function can predict myocardial infarction which has clinical value.
17.ST function which can check the exact time and length of myocardial ischemia in 24 hours.
