Gutluk is a natural animal growth promoter (AGP) alternative that regulates intestinal microbiota through inhibition of bile salt hydrolase (BSH). It is developed by CJ Bio via machine learning technology to screen key ingredients as BSH inhibitors (BSHI).  

It is well known that enteric diseases are mostly caused by overgrowth of intestinal pathogens, leading to increased competition for nutrients and reduced productivity.  AGP has been widely used to control the overgrowth of enteric pathogens and increase productivity. It is noticed that the use of AGP significantly reduced BSH activity that is protecting pathogens from bactericidal activity of bile salt. However, due to development of antibiotics resistance in farm animals, lots of AGP alternatives such as prebiotics, probiotics, organic acids, enzymes and plant extracts have been promoted, but only antibiotics and high dose of ZnO and CuSO4 have been shown to inhibit BSH.  Compared with other AGP alternatives, Gutluk  showed super bactericidal effect on Enterotoxigenic E.coli (ETEC), C.perfringens, and S. gallinarum (Table 1). In addition, Gutluk showed greater anti-inflammation and anti-oxidative effects than other AGP alternative (Figure 1).

In Indonesia, one commercial trial with 6000 Hy-line hens was conducted to show that after two weeks of adaption period (without Gutluk addition), adding 300 g Gutluk per MT feed significantly increased egg production (Figure 2), daily egg Mass was increased by 4.4% and feed conversion ratio was improved by 9 points. Thus, Gutluk is a natural product inhibiting BSH activity and effectively replaces AGP targeting to control intestinal pathogens and improve the egg production as well.

In recent years, the reduced protein diets balanced with crystalline amino acids (AA) for broiler chickens have been developed due to economic, environmental and bird welfare advantage. However, this reduced protein diet quite often results in adipose fat accumulation and sometimes compromises chicken performance. In practice, reduced protein diets should be formulated by experienced nutritionists.

Ideal amino acids profile

In reduced protein diets, digestible lysine concentration should be the first limiting AA. Based on the ideal AA profile, other essential AA concentrations including Methionine, Threonine, Valine, Isoleucine and Arginine need to be increased accordingly while the dietary lysine concentration is increased. When the dietary lysine concentration is fixed, increasing any other essential AA will not improve chicken performance but depressed the liter quality due to increased N excretion. On the other hand, when any other essential AA is deficient, Lysine becomes surplus and increases carcass fat. Figure 1 clearly showed that in reduced protein diets, when dietary Arginine and Histidine are deficient, it is very likely resulting in fatty carcass. Therefore, in recent protein diets, digestible Arginine and Histidine to digestible lysine ratios were increased to be 115% and 40%, respectively.

 

Figure 1. Effect of essential AA on abdominal fat content in reduced protein diets

Methionine sources

In broiler chicken feed ingredients, Methionine is the first limiting AA and practically be overused in chicken production. Figure 2 clearly showed that compared with DL-methionine and DL-HMTBA, L-Methionine significantly reduced fat composition in breast meat.

Figure 2 Effect of Methionine from different sources

The optimal digestible Lysine to apparent metabolizable energy (AME)

In reduced protein diets, if dietary AA is not balanced based on the ideal AA profile, the extra energy is required to excrete surplus energy. In contrast, if dietary AA is balanced based on the ideal AA profile, surplus energy will be accumulated in chicken body. Figure 3 is shown that reducing 100 kcal/kg in reduced protein diet significantly reduced abdominal fat in chicken carcass. It is suggested that the optimal Digestible Lysine to AME in reduced protein diets will be 100, 90, and 80% in the starter, grower, and finisher periods, respectively.

Figure 3. Effect of higher digestible Lysine to AME ratio on abdominal fat contents in chicken carcass

Supplementation of β-Mannanase

Soybean meal, canola meal and faba beans contain β-Mannan about 0.8, 0.4 and 0.4%, respectively. Β-Mannan can provoke the activity of innate immune system which leads to unnecessary energy cost for broiler chickens. Therefore, adding the exogenous β-mannanase to the reduced protein diets could save some energy cost and reduce carcass fat. Figure 4 is shown that in the reduced AME diets, adding β-Mannanase could further reduce the abdominal fat contents.

Tannic acid is a specific form of tannin and a type of polyphenol. It is defined in AAFCO as 582.20 for a source of flavour. Quebracho extract is a big complex polymer of tannin (MGM-S), specially for ruminant animals.

MGM-S has been approved to inhibit the growth and activity of methanogenic archaea in the rumen, which are responsible for producing methane as a byproduct of fermentation. It can alter the composition and activity of microbial populations, stimulating saliva production, favouring the growth of bacteria that produce less methane and increasing the proportion of propionate. Therefore, it can prevent the accumulation of lactic acid in the rumen and improve rumen pH stability, working together with marine-sourced calcium carbonate to reduce the risk of rumen acidosis.

MGM-S has been investigated for its ability to reduce the incidence of frothy bloat, which can occur when cattle consume rapidly fermentable feeds, such as high-grain diets in feedlot. MGM can help to reduce the stability of foam in the rumen by binding dietary proteins and maintain a more stable rumen environment, preventing the formation of gas bubbles and reducing the risk of bloat.

MGM-S also shows its anthelmintic effects due to its ability to disrupt the physiology and life cycle of parasites such as nematodes and coccidia.

Freshly milked dairy collected on-farm. Feed supplements like MGM-S are helping improve both milk composition and rumen health in today’s herds.

Adding 70 g MGM-S per day per cow could produce 1.2% more fat and increase milk protein by 3.3%. Adding 0.15% MGM-S to beef cattle diets for 93 days with initial body weight at 180 kg, achieved daily weight gain 180 grams and FCR was improved by 6.72% (8.18 vs. 7.63).

Phosphorus (P) is an essential and expensive mineral for pigs, crucial for bone development, energy metabolism, and various physiological processes. The phosphorus requirement for pigs is dependent upon:

(1)   An adequate supply of P in an available form,
(2)   A suitable ratio of available Ca and P in the diet, and
(3)   The presence of adequate vitamin D.

Phosphorus in protein sources of animal origin is largely inorganic and has a high relative bioavailability (RBV). However, the RBV of P in meat and bone meal (MBM) is variable (67-90%). Phosphorus in inorganic supplements also varies in RBV (Table 1, Jondrevvill and Dourmad, 2006).  The RBV of MCP and MDCP is strongly affected by citric acids solubility and ammonium citrate solubility, respectively. Usually, the water solubility for MCP and MDCP is required to be greater than 80% and 50%, respectively.

Table 1. RBV and the digestibility coefficient of different inorganic P sources

In cereal grains and oil seed meals, about 60-75% of P is organically bound in in the form of phytate. The exogenous phytase supplementation can result in major improvement in RBV of phytate P. The higher temperature during pelleting of diets can reduce or destroy phytase activity and thermal stable phytase is available now to resist up to 85 ˚C pelleting temperature (Table 2).

Table 2. VTR phytase activity and heat stability (North Carolina State University)

To limit the loss of activity, Phytase must be made resistant to digestive proteases. After 2 h in contact with pepsin, VTR phytase retained about 93% of their initial activity (Figure 1).

Figure 1. The effect of pepsin on phytase activity.

A wide Ca-to-P ratio lowers P absorption and resulted in reduced growth and bone calcification. Ca and P requirements for maximizing bone strength are at least 0.1 percentage units higher than that maximal body weight gain. Although every 1-gram phytate P released by phytase could spare 1.33 grams Ca availability, a suggested ratio of total Ca to total P is between 1:1 and 1.25. It is noticed that the Ca in calcitic limestone is highly available, but Ca in dolomitic limestone is only 50 to 75% available.

An adequate vitamin D is necessary for proper metabolism of Ca and P, but a very high level of vitamin D can mobilize excessive amounts of Ca and P from bones.

Did you know synthetic oil was initially developed for aeroplanes, not automobiles?

While it was first created to withstand the extreme conditions of aviation engines, synthetic oil has since become the preferred choice for modern high-performance car and truck engines and transmissions.

Why? Because synthetic oil offers four key advantages over conventional mineral-based oil, making it superior in terms of performance, efficiency, and longevity. 

As a distributor of Chevron Phillips Chemical’s extensive Synfluid® range of PAOs, Redox plays a key role in delivering premium synthetic base oils to the market. These polyalphaolefins (PAOs) are the foundation of high-quality synthetic lubricants, ensuring equipment runs smoother, lasts longer, and performs at its best—even under extreme conditions.

In the latest episode of their HISTORY of MOTOR OIL series, The Motor Oil Geek visited Dr. Ken Hope and his team at Chevron Phillips to explore the science behind synthetic base oil. They take a deep dive into the production process and uncover the specific properties that make synthetic oil an essential choice for today’s high-performance engines.

 

 

As automotive technology advances, the demand for high-quality lubricants continues to grow. Understanding how synthetic oil is made—and why it outperforms conventional oil—helps drivers and industry professionals make informed decisions about engine maintenance and efficiency.

Glucose oxidase (GOD) is exogenously produced by specific fungi fermentation to oxidise β-D-Glucose into gluconic acid and hydrogen peroxide, consuming large amounts of oxygen.

GOD helps to extend shelf life of wet pet food, preventing rancid and spoilage caused by oxidation and microbial activity. In pet’s gut, it creates an environment that is less favourable for the growth of aerobic microorganisms including mycotoxins. Apart from gluconic acid, the hydrogen peroxides production could directly kill some virus, pathogens, and parasites. Therefore, it is considered as a new natural preservative and antioxidant.

As early as 1962, GOD was found in honey to produce gluconic acid and hydrogen peroxide, demonstrating its reputed wound-healing and antiseptic properties. GOD has been defined in the Association of American Feed Control officials (AAFCO) list as 70.3 and is widely used in food and animal production.  As a naturally derived enzyme, GOD can be marked as clean-label ingredient, which is increasingly popular with pet owners seeking natural preservatives in pet food products.

In general, adding 2000 U/kg dry matter or 200 g/MT dry matter GOD to pet food could be used as a preservative and antioxidant.

Low protein or reduced protein diets have been widely used in pig industry to save protein sources and reduce nitrogen excretion. In reduced protein diets, amino acids (AA) balance is crucial for pig’s performance not to be compromised.  

Currently amino acids balance is achieved by the supplementation of crystalline L-Lysine, L-methionine, L-threonine, -L-tryptophan, L-Valine and L-Isoleucine based on the ideal protein profile. In practice, if only adding first 4 limiting amino acids to reduced protein diets, it may result in lower plasma valine, isoleucine, histidine, and arginine. Other amino acids such as lysine, methionine, threonine, tryptophan might become surplus and cannot be used by pigs (Figure 1). Histidine is the seventh limiting AA in typical diets fed to swine and may require supplementation in reduced protein diets (Figure 2). Among cereals, barley has the lowest histidine contends and therefore, barley-based diets may result in histidine deficiency.

Histidine is an integral component of a broad set of tissues including skin, bone, ligaments, and muscle. It is a component of haemoglobin and important constitute of dipeptides anserine and carnosine. High concentrations of carnosine and anserine have been found in the brain and muscles because of its high antioxidant activity.  It also stimulates the digestive secretion of gastrin, a hormone that is essential for digestion of dietary protein. Histidine deficiency could induce a decrease in amino acids oxidation and a decrease protein turnover.

Recommended standardized ileal digestible (SID) histidine to lysine ratio for pigs at 7 to 11 kg body weight from NRC (2012) is 0.34, which was based on growth performance and plasma histidine concentration. Recently, Cheng et al (2023) indicated that SID histidine to lysine between 0.35 and 0.41 in diets fed to nursery pigs at 7 to 11 kg body weight enhanced intestinal health and maximized concentrations of histidine-containing proteins.

Wearing and tearing on horse joints in activities like racing, jumping, and heavy work, can result in arthritis or inflammation. Oral joint supplements are often used to support cartilage health, reduce inflammation and improving joint fluid.   

Glucosamine and chondroitin sulphate

These two supplements usually work synergistically to help prevent cartilage breakdown and support joint elasticity.

There are three forms of commercial glucosamine: glucosamine hydrochloride, glucosamine sulphate and N-acetyl-D-glucosamine (NADG). Glucosamine hydrochloride is the most stable form and more effective to prevent the degeneration of cartilage. It is usually recommended that 12 grams of glucosamine and 2-6 grams of chondroitin per day in a 600 kg horse.

Activities such as racing, jumping, and heavy labor can lead to joint wear and tear in horses, often causing inflammation or arthritis.

Incorporating joint supplements into a horse’s diet can significantly improve joint health and mobility, particularly for those engaged in demanding activities. With the right combination of glucosamine, chondroitin sulfate, MSM, yucca extract, and UC-II, horse owners can help reduce inflammation, support cartilage, and maintain overall joint function, ensuring their horses remain healthy and active.
