對(duì)于魚類，肝臟的保護(hù)是首當(dāng)其沖的，但是對(duì)于養(yǎng)殖魚類，由于在比較短的時(shí)間內(nèi)取得養(yǎng)殖效益最大化，所以魚類的肝臟很多都是超負(fù)荷運(yùn)轉(zhuǎn)。肝臟代謝好，魚類的營(yíng)養(yǎng)代謝也就好了，健康狀態(tài)也就好了很多。

I have few questions to Mr. Piet Verstraete.
I saw the Organic Acid and the Probiotics have been mentioned on the PPT of your company.
1 What kind of Organic .Acid is best for our fish or shrimp culture? Who to use? The factory can add it in their feed formula or we have to add it in to feed before we feed our fish or shrimp?
2 About Probiotics, Probiotics can not add in the feed formula of the factory I think as while they producing feed they are using high temperature to dry the feed, it will kill all bacteria. So in your mind, how do we use the probiotics? Should we add some probiotics into our feed with some binder or mix feed with some probiotics and add in water let them ferment before feeding?
3 I think you have seen that in other Country like Thailand and Malaysia, they use the Auto Feeder in their shrimp ponds while we still using workers to feed our shrimp. Do you think the way how the Auto Feeder feeding shrimp(feed less but feed often) is more suitable for the shrimp? Should we start using the Auto Feeder now in our shrimp ponds? 作者: 綠豆的眼睛 時(shí)間: 2013-1-18 10:15

Organic acids:1) First of all we have to select the best molecules, in the case of Novus we selected propionic acid (effective for feed hygiene againts mould) and formic acid (effective againts Gram negative bacteria like Vibrio). We have tested the combination in vitro and in vivo and found good results. 2) Second, we have to make the product applicable in the feed. Novus organic acids can be applied as top coating, but also in the feed itself (because the produc tresists to the high temperatures used in shrimp feed pelleting or fish feed extrusion).3) Third, the organic acids have to prove it's economical benefit, we have documented field trials with very positive return on investment, due to higher survival, and better growth and FCR. We believe that the organic acid combination used by NOVUS, not only reduce the gram negative bacteria, but also has a positive on digestibility. Another succesful application, has been the use of Novus organic acids to reduce problems with white feaces in shrimp.
Most feed probiotics are used in top coating, often mixed in an oil emulsion and then coated on the pellet at the farm. Novus is working on probiotics for in feed use, but this needs some additional reaserch on applying our technologies to improve resistance to high processing temperatures.作者: 水寶寶 時(shí)間: 2013-1-22 17:06
ramakanta nayak: In Thailand shrimp when the fish meal prices was growing drastically in 2009 and the feedmillers were not allowed to compromise on the Crude Protein level and farmers interested for fast and more growth with high yield, feedmillers started looking for alternatives. It is during thsi time Novus proposed on aholistic model approach on fish meal replacement with a complete balance of amino acids, minerals and addition of functional additives such as antioxidant and organic acids.
Historically the Thai feedmillers were using in a range of 25-30% FM in shrimp diets but today they use only 12-15% and sometimes even lower, even though the prices of local fish meal has come down to 1200$, but by blanacing with essential amino acids such as methionine, lysiine, minerals such as Zn and Se and using performance products to improve the immunity and fisht against pathogenic bacteria such as organic acids they have successfuily kept the high standards of growth and total yield per ha of culture area. 作者: syusuke 時(shí)間: 2013-1-22 17:12
Gut health and survival is the biggest challange in shrimp culture today, the challanges are from bacterial and many due to the impact of feed ingredients. For bacterial challanges what in successful countries are doing is managing by using Gut Environment Modifiers whihc can be AFG (organic acids) and NE150 (essential oils). these products protect the animals against pathogenic bacteria, improve the digestibility of the feed, improve the FCR, improve growth and suvival. In terms of feed ingredients I think its high time to look for alternative proteins and move away from the fundamental approach of high fish meal diets and balance the feed with limited amino acids such as methionine and moving from inorganic minerals to chelated minerals. Many times also it has been seen when we shift to plant proteins from animal proteins we add to the gut problems because the plant proteins have high anti nutritional factors, mycotoxins and low digestibility, so in order to have the best nutrition available its not only balancing at protein levels but on all factors as mentioned earlier and adding functional additives such as antioxidant to prevent oxidantion of the feed, mycotoxin binders and attractants.作者: 水寶寶 時(shí)間: 2013-1-22 17:30
魚體偏肥是否和長(zhǎng)期使用膨化料有一定關(guān)系？
Piet：With extruded feeds, we are using often using higher energy in the feed. There is a relation between the digestible protein/digestible energy ratio and fat fish. too much digestible energy and not enough digestible protein will affect the fish shape negatively.
Nayak:
Japonicus and Monodon have a habit of going to the bottom of the pond as compared to the white shrimps whihc stay in the water column, these differences in color of the shrimp and the soft shell to a large extent is due to bad pond bottom with high ammonia and hydrogen sulphide. Corrective measures is use of probiotics and remove of sludge or bottom water exchange.Make sure the alkanity and the pH is also optimum and the DO early morning is sufficient.Avoid over feeding and control FCR, right source of minerals for the animals is also essential to vaoid blue shrimps and soft shell so farmer should ask feed mills to use chelated minerals.作者: XXT 時(shí)間: 2013-1-22 17:33

Auto feeder is the latest technology in optimizing feeding and use of minimum labor which is become expensive. By this model we avoid over feeding which can be human error as well as continued feeding avoids leaching of many nutrients from the feed as it is eaten immedeately the moment feed is injected into the pond.Standardizing is an important step in auto feeder and then only get good FCR. In Thailand people have achieved FCR to the tune of 1.1 - 1.2 in shrimps with high stocking density of 100 to 150 pcs per sq.m作者: 陶青燕 時(shí)間: 2013-1-22 17:41
鳊魚的粘液?jiǎn)栴}：

鳊魚黏液的問(wèn)題首先肯定是肝臟的問(wèn)題,目前國(guó)內(nèi)鳊魚的高脂肪已經(jīng)超過(guò)了這個(gè)品種的最適需要量.如果要追求生長(zhǎng)速度,能量降下來(lái)的可能性很小,所以首先是要提供高品質(zhì)的油脂,避免氧化油脂及霉菌毒素對(duì)肝臟的損傷.另外,即使使用特別優(yōu)質(zhì)的原料,肝臟損傷對(duì)于這種品種也是風(fēng)險(xiǎn)很高的.因?yàn)楦咧救占Z本身會(huì)導(dǎo)致自由基的大量產(chǎn)生,如果機(jī)體不能消除這些自由基,損傷是在所難免的.有大量研究表明,高脂日糧會(huì)導(dǎo)致大量器官的損傷,其中肝臟自由基的數(shù)量會(huì)上升4倍左右.這也是為什么大家特別是養(yǎng)殖戶使用一定的vc會(huì)有一定的效果。但這不是最經(jīng)濟(jì)有效的辦法，諾偉司的體內(nèi)抗氧化劑專門針對(duì)體內(nèi)自由基，是更專業(yè)經(jīng)濟(jì)有效的辦法。作者: syusuke 時(shí)間: 2013-1-22 17:43
Piet Verstaete: With extruded feeds, we are using higher energy, higher energy can bring some nutritional stress if overfeeding occurs (liver problems) or if the formula is not balanced (amino acids, vitamins, minerals, etc..). Also in extruded feeds we are often using more oil in coating and the oxidation of the oil can induce stress. Too much carbhydrate will also cause liver problems and fish stop feeding. Also, feeding higher energy feeds uses more oxygen for digestion.On the farm side: More checks on oxygen levels on the feeds are needed when feeding higher energy diets. So the time of feeding and the ration size should be managed better with extruded feeds compared with pelleted (lower energy feeds).On the feed size: extrududed feeds should be well balanced and if a lot of oil is coated, the oil shoudl be fresh band treated with anti-oxidants. It is also wise to increase the levels of vitamin E and vitamin E to reduce the stress of the fish and some phospholipid, choline and inositol to protect the liver.作者: XXT 時(shí)間: 2013-1-22 17:48

Piet Verstaete: an alternative of controlled quality, but more expensive is krill meal. Alternatives to krill meal to improve moulting is to increase phospholipid levels, cholesterol levels and/or add bile salts.
Piet Verstaete: Cholesterol is less an less used because of its high price, generally we try to improve the cholesterol available from ingredients by using emulsifiers and increasing phospholipid levels.作者: 陶青燕 時(shí)間: 2013-1-22 18:07
