Strategic use of methionine to impact reproduction of the dairy cow

Wed, 17 May 2023 11:58:50 GMT

This webinar links nutrition with dairy health and reproduction. Health, particularly after calving, impacts reproductive outcomes two-to-four months later. Poor health and reproductive performance can each lead to undesirable cullings.

The challenge is to connect these two maladies. They don’t occur at the same time, so few people make the connection between them. During the webinar, the speakers give clear explanations of how the nutrition after calving is connected to reproductive problems and higher culling rates, and provide examples of how nutrition, specifically the essential nutrient methionine, helps cows overcome these stresses.

Ensure a good start to the lactation cycle of the dairy cow

Mon, 24 Apr 2023 11:00:07 GMT

This webinar gives you an appreciation for the science behind the indexes (LFI, LAI, PIRI) used to gauge the liver health of cows during the transition period. The discussion includes how to use and interpret the indexes, and their importance in guiding management practices. The conversation closes with why it is important to assure that the pre-fresh diet contains enough methionine to help cows cope with postpartum challenges.
To summarize, we discuss the importance of the transition phase to the whole lactation cycle, what areas to work on to lower unwanted cullings, and the tools we have to assess the challenges cows experience during the peripartum period.

Features: Dr. Johan Osorio, Assistant Professor, One Health, Virginia Tech, USA. Dr. Erminio Trevisi, Head of Department of Animal Sciences, Food Nutrition, Università Cattolica del Sacro Cuore, Italy. Dr. Daniel Luchini, Head of Ruminant R&I, Adisseo.

History of AA balancing and solutions for improved milk and components

Wed, 29 Mar 2023 09:02:49 GMT

This webinar will give you an appreciation for the history of the science behind amino acid (AA) balancing, the amino acids of most importance, and what improvements to expect in milk yield, fat yield and protein yield when effectively achieving target levels of lysine and methionine.
Dr. Chuck Schwab’s Ph.D. work was the catalyst for the development of AA balancing as we know it today. The first milestone to the practical implementation of AA balancing was the publication of the integrated INRA AA formulation system in 1993.
Initially AA balancing was only thought to have an effect on milk protein. Today a recent summation of 25 production trials in which rations were AA balanced using Adisseo rumen protection technologies shows clearly that AA balancing affects positively milk fat synthesis as well as milk protein.
The trial results show an increase of 1.7 kg/day in energy corrected milk (ECM), +60 g/day in milk protein and +80 g/day in milk fat, corresponding to average increases of +0.13% and +0.16% in protein and fat content respectively. Trial results have been replicated in commercial dairy farms, but formulation practices will determine how successful the results of AA balancing will be.

Importance of Dietary Methionine and Selenomethionine on Health and Reproduction

Thu, 14 Oct 2021 14:23:00 GMT

Webinar held on October 14th, 2021.

For the session's questions and answers, click here.

Speakers: Dr. Darren T. Juniper (retired), Former Associate Professor of Animal Science, University of Reading, England and Dr. Phil Cardoso, associate professor at the University of Illinois at Urbana-Champaign.

Both methionine (Met) and selenium (Se) are essential to dairy cow performance. Dr. Phil Cardoso, Associate Professor of Animal Science, University of Illinois, USA, says methionine, an essential nutrient, is heavily involved in the metabolic pathways of dairy cows. Methionine, however, cannot be synthesized in the required quantity. Research that extends to the 1970s shows that regularly meeting dairy cows’ methionine needs supports not only production – milk, milk protein and milkfat – but also animal health and reproduction. This includes metabolic diseases, timely breed backs and full-term pregnancies. For these reasons, methionine supplementation is becoming as common as daily vitamin and mineral supplementation.

Dr. Darren T. Juniper (retired), Former Associate Professor of Animal Science, University of Reading, England, reports that selenium is an essential trace element with key functions in antioxidant defense and immunity and inflammatory response modulation of the body. Feeding selenium in the form of SeMet, over inorganic sources or other organic selenium, is preferred because SeMet is metabolized as a constituent of the methionine pool. This leads to a storage depot of selenium being created in body tissues. Increased muscle and tissue reserves of selenium can enhance the resistance of livestock to stress and diseases, and represent a key strategy to help fight stress.

Dr. Phil Cardoso is an associate professor at the University of Illinois at Urbana-Champaign. He received his D.V.M. and M.S. degrees from the Universidade Federal Do Rio Grande do Sul in Brazil and his Ph.D. from the University of Illinois. Since 2012, Phil has established a unique program that seamlessly blends his teaching, extension, and research efforts. The impact of Phil’s Dairy Science program is in placing students in applied positions and academia. Phil and his students have published over 75 peer-reviewed manuscripts (original research and invited reviews) and three invited book chapters to date. The program builds from questions asked by dairy producers and focuses on having the dairy cow’s diet as a medical prescription for performance, health, and reproduction. That is achieved by understanding the impact of nutrition on metabolism, reproduction, and health in dairy cows, as well as the mechanisms of metabolic adaptation to stressors and forage quality.

Dr. Darren T. Juniper worked within the University of Reading’s Animal Science Research Division. He gained his doctorate degree from Reading in 2003 – titled “Diet and Endocrine Responses in Beef Cattle.” He has been involved in animal production research for more than 30 years. During this time, he worked with most classes of domestic livestock (ruminant and monogastric) – covering a diverse range of research topics. Over the last 15 years, Dr. Juniper has researched trace element nutrition, primarily selenium and iodine in animal diets. His selenium-based research has focused on the effects of selenium source on aspects of animal and human health, as well as the deposition of selenium in the products and post-mortem tissues of both ruminant and monogastric livestock.

Webinar #1: Oxidative Stress in Animal Production

Thu, 04 Mar 2021 10:00:39 GMT

Speakers: Prof Peter Surai, Dr Mario Estevez and Dr. Pierre-André Geraert

The basis of oxidative stress (Prof Peter Surai) and its impact on meat quality (Dr Mario Estevez) & share questions and answers during the roundtable.

Questions and Anwers

Q: A comment on flavonoïds, even if they are absorbed at low level some of them play an indirect role in inducing at gene level endogenous antioxidant systems.

Reinforcing the anti-oxidant defenses of the gut definitely improve its resistance to aggressive factors such as dietary ones (induced by mycotoxins for instance) or induced by microorganisms (bacteria, virus). Polyphenols and flavonoids may bring antioxidant benefits reinforcing the host response to xenobiotics.

Q: Is there a significant difference on the meat between chicken fed with Organic selenium and another fed with mineral selenium?

We assume that you mean organoleptic properties: improving the antioxidant status of the meat often is "indirectly" perceived by consumers influencing their choice. The conservation of the meat is also improved reducing the changes in color, texture,.. during storage or processing. Drip losses are clearly reduced when birds receive an organic selenium source compared to a mineral one.

Q: Oxidative impaires male fertility .. What about female ?

Indeed, the spermatozoids are clearly affected by oxidation. But ovocytes and particularly their membrane is also rich in polyunsaturated fats and prone to oxidation. Most parameters linked to egg production such as the export of vitellogenin by the hepatocyte toward the ovary is conditioned by membrane phospholipids. Preserving them from oxidation will help to enhance fertility. Hatchability is also clearly affected by oxidative stress situations and can be restored by using the right antioxidant solution.

Q: You said free radicals are used as weapons against bacteria, play a role of messenger: what about (too) high antioxidant intake?

Indeed, you're right. Free radicals are normal elements in the metabolism that help our body to get rid of xenobiotics. Antioxidant have to be balanced and an excess of one will not compensate for a deficiency of another and might event counteract the benefits of their nature. Proposing a balanced of efficient antioxidant solutions is thus key to improve animal performance under challenging conditions.

Q: Is oxidative stress affecting fertility ?

yes indeed, hot conditions and ageing are good examples of oxidative stress that affect fertility. An optimal balance of antioxidants has long been shown to improve fertility in a wide range of animal species including human.

Q: Is oxidized fat in the diet a source of oxidative stress?

Yes, oxidized fat can induce some toxicity depending the level and thus increase oxidative stress to the animal. It has long been worked at, but nowadays it is sometimes difficult to link the actual used index (iodine, …) to the decreased performance. However, lipid peroxydes have clearly a negative effect on sensitive molecules to oxidation. Antioxidant systems can help to alleviate those negative effects, particularly the selenoprotein Glutathione peroxidase 2 have been demonstrated to detoxify different lipid peroxides.

Webinar #2: Understanding Gut Health in poultry production

Thu, 04 Mar 2021 10:00:39 GMT

Speakers: Prof Theo Niewold; Prof Filip Van Immerseel and Dr. Pierre-André Geraert

Watch more on gut health, from gut microbiota (Prof Filip van Immerseel) to gut inflammation (Prof Theo Niewold) & share questions and answers during the roundtable.

Q&A Session held during the live:

Q: Are the biomarkers available commercially?

Lots of biomarkers can be easily measured in analytical labs, however reference values are still missing to help define what is a dysbiosis situation vs a normal one. Scientists are working hard to get such figures and we can expect to have practical and efficient tools in the coming years.

Q: Hello Pierre-Andre, Greetings from Venezuela. What are the residual effects of misuse and abuse of AGP and antibiotics in general, in pigs and poultry?

The world misuse or overuse of antibiotics in both humans and animals has conducted to these antimicrobial resistances that we observed worldwide. In countries with a significant duration of ban on AGP's and more prudent use of antibiotics a clear reduction of antimicrobial resistance has been reported (EFSA reports, 2015-2016).

Q: One of the alternatives you mentioned was herbs, do you think that they can help us to control Clostridium?

It is important to consider that no one alternative can be considered as the only solution to get rid of Clostridium perfringens. However some solutions such as some Bacillus subtilis can exhibit a specific efficiency on such a pathogen bug. Essential oils and herbs could have some effect on the host to reinforce its resistance as well as on the pathogen by itself. But guaranteeing consistency and delivering to the right level of the intestine are still important issues for those alternatives.

Q: Besides improving animal growth and wellbeing, does improving animal gut health help to fight against viral infections?

Reinforcing the gut health or better speaking the gut wall will improve resistance of the animals to challenges through bacteria, parasites and virus. We have also observed that a mycotoxin challenged gut wall would better resist if there was supplementation with a specific Bacillus subtilis through better gut wall integrity and gut immune system.

Q: Can externally supplemented butyrate has the same potency as internally synthesised by bacteria?

Very interesting question not yet solved by the experts. When giving formulated butyrate to be delivered at the intestinal level the positive effect on the enterocytes and gut mucosa can be observed. However, when influencing the microbiota profile stimulating the butyrate bacteria producers directly or indirectly through the cross feeding would give a localized and dedicated effect with more long term consequences through the rebalancing of the microbiota.

Q: I thought organic acids are best alternative for AGP, also most economical one. Is it correct?

Organic acids can contribute to control microbiotia through both pH reduction and their radicals penetrating into the bacterias. However, they are not specific to any bacteria and might also affect commensal bacteria that could impair performance as observed at high doses or very young animals. Moreover, coating is also important to consider.

Q: What is the difference between probiotics and prebiotics? Which kind of alternative will be more developped in the next years according to you?

Probiotics are live micro-organisms which, when administered in adequate amounts, confer a health benefit to the host. Conversely, prebiotics are nutritive substrates that are only metabolized by the gut microflora to benefit to the animal performances and health. Scientists are working more to develop nutritional solutions based on combination, such as symbiotics which combine pre and probiotics, to guarantee the efficacy of those alternatives.

Speakers: Dr Jean Noblet, Dr Pierre-André Geraert and Pierre Cozannet

Answer:
I accept that animals respond maybe more to amino acids because the birds are selected and raised for depositing proteins and so amino acids supply is a very important pusher in the system.

Wed, 07 Oct 2020 00:00:00 GMT

Speakers: Dr Jean Noblet, Dr Pierre-André Geraert and Pierre Cozannet

Last June, we completed the release of a series of 8 Short Educational Videos on Net Energy (NE) presented by Dr Jean NOBLET (ex-INRAe) who largely developed the NE concept in swine and participated to the development of NE for poultry during his scientific career.

Net Energy: everything you wanted to know about NE but were afraid to ask! This SEV series was designed to better understand the concept of NE, the methods to determine NE, how to calculate NE of ingredients and diets, the impact of NE on feed formulation, and the benefits in terms of performance and usage of additives.

During this webinar, Dr Jean Noblet, Dr Pierre-André Geraert and Pierre Cozannet discussed on : Net Energy, Feed Formulation and animal performance: How to move from theory to practice.

Questions and Answers session

As mentioned during the live webinar, the “liquid additive equipment maintenance check list” can be downloaded via: http://bit.ly/39SbeQn and to know more click here.

Can you comment on the sequence of addition of the different liquids in the main mixer?

First, a dry mixing time is needed to homogeneize the solid ingredients. Before addition of micro-liquids, it can be quite short (a few seconds). Then comes the addition of liquids -time depend on quantity and flow). They can be applied simultaneously since the flows do not overlap. Lastly, the third mixing time allows to finalize the repartition of liquids within the batch. All automation systems have different approaches to consider these different times but things must be cleared between the feed manufacturer and the PLC company.

Compared to powder dosing, the injection of liquid requires specific equipment whose maintenance is more delicate. What are the practices to recommend for monitoring "weighings"? (pump, plastic or metallic material, injector ...)

Maintenance of liquid system is not a big deal. It consists mainly on checks and verifications. Please have a look to Adisseo's check-list proposal.

Is the premixing of liquids a recommended practice?

As far as possible, managing each liquid seperately is recommended (from storage to spraying). But if there is no adverse interaction, liquids can be put together before addition in the mixer.

How to ensure the good dispersion of the active liquid materials in the mixer?

Spraying is a matter of choice of nozzles (number, type, size, angle), location, pressure and viscosity in some cases.

From the point of view of the incorporation of liquids, are there differences in behavior between the different types of mixers?

The equipment supplier must consider the type of mixer (single/double shaft - ribbon/paddle...) to implement the nozzles. Spraying quality is of bigger importance than the mixer type. The filling ratio of the mixer is also of importance (distance between the sprays and the feed; are the shaft and ribbon or paddles covered by the feed?).

If we have powder micro ingredient and want to apply it with oil on feed, what would be the suggested mode of application, as oil suspension (powder directly in oil), as water dispersion (powder into small quantity of water and than water solution into oil) or as an emulsion?

It mainly depend on the physical and chemical properties of the additive (particle size, solubility, rate of inclusion, stability....). Today this topic is more research program.

Is there any limit as for the amount of additives that recommend applying with a post-pellet dosing equipment? (enzymes and/or probiotics)?

Fortunately, additives are quite concentrated. Even if the manufacturer wants to spray 2 or 3 different products, an addition of 1 liter per ton or a bit more is doable.

What is your opinion about the feed mills having PPLA system without sieving the pellets before liquid application. Can this system be accurate enough?

Of course, this is not the best option. THe final result will then depend on the 3 factors: initial quantity of fines in the feed, pellet durability, stresses during feed storage, transportation and distribution to the animals.

Which is ithe most efficient Post pellet liquid applicator available now? For Fish feeds, With less cost, Any options...Pls explain the working if possible.

Many suppliers propose proper PPLA systems. For fish feed, adding liquids continuously in a drum coater is common. A more recent technique is vacuum batch coating to apply high levels of fats and oils. Liquid additives are applied at the same stage.

Thank you for the ongoing live about liquid additives in the feed mill. We often face the following question from our customers on liquid application system.Kindly requesting your insight on the same. Can we mix macro ingredients (oil) with Micro ingredients(Amino acids/Acitifier) while spraying into batch mixer? Or All Micro ingredients together ? Thank you for your clarification.

As far as possible, managing each liquid seperately is recommend (from storage to spraying). But if there is no adverse interaction, liquids can be put together before addition in the mixer.

How should the liquids and palatabilizer be added together or separately?

In general, palatants require less accuracy in term of dosage and spraying compared to other types of additives. They can be easily sprayed on a mechanical conveyor. This is why they are independent most of the time. Before mixing with another liquid, incompatibility of molecules must be assessed.

Is dry mixing necessary in the mixing time or we can skip it and start liquid spray after loading?

With flowmeters we can have dedicated lines and mixing them into the manifold is optional. We can use different manifolds for those liquids which could not be mixed. It is a closed and cleaner system.

How can we choose between hidraulic or atomizing nozzles.

Refering to Post-Pelleting Liquid Application, the optimum is to create micro-droplets, not a mist. Pure hydraulic nozzles will not produce micro drops, so air is necessary but no so much because we want to get a fine dosing (micro drops) but avoid nebulization (mist).

How do I define the maximum inclusion based on free water resulted from this liquid additive?

In formulation, water content of liquid additives must be considered the same way as for solid ingredients (a value in matrix). In practice, water content of additives is never limitating. With weighing scales it is necessary to add each liquid separately and sometimes mix them before addition into the mixer or use dedicated scales for each liquid. The scaled vessel always keeps traces of the previous mixture and is more difficult to flush and clean.

What are the benefits of flowmeters comparing to weighing scales?

With weighing scales it is necessary to add each liquid separately and sometimes mix them before addition into the mixer or use dedicated scales for each liquid. The scaled vessel always keeps traces of the previous mixture and is more difficult to flush and clean.

What are the advantages of mass flowmeter compared to volumetric flowmeter?

A mass flowmeter measures Mass Flow (kg/min), regardless the actual density value. If there are changes in density value, the flow meter corrects it automatically.
A volumetric flowmeter measure Volume Flow (l/min). As the dosing is made in mass, it is necessary to change from Liter to Kg in the electronics using the actual density value. If the density varies, the conversion to Mass could be slightly affected and alter dosing accuracy.

What is the best sequence for adding different liquids? Is it ok to spray all liquids in the mixer at the same time, if the mixing time is very short?

Please refer to the 1st question in the Forum.

After a mixer profile test, What should we recommend a customer when the CV of the liq is not as good as the powder? What are the advices to improve CV for liquid?

This is a very open question. Apparent heterogeneity can have different sources: actual quality of spraying (place, geometry, pressure, steadiness of the flow...). Let's not forget the analytical process i.e. sampling and lab analysis.
