Layer chicken loose/watery mucoid droppings

Natural solutions based on herbs and essential oils are showing very promising efficacy in countering the deleterious effect of loose dropping in poultry. Essential oils counter the pathogenic activity of harmful bacteria due to its anti-quorum sensing activity. The herbal phytogenic constituents and essential oils work in synergy to prevent and treat GIT related problems in poultry and pigs. Salc ...

Layer chicken loose/watery mucoid droppings

Caecal droppings (yellow pasty mucoid droppings) in layers can be very common, caused by Brachyspira infections. We found them to be present in most free-range flocks, causing 20% drop in production and an additional 10% mortality if untreated. In cage sheds, flies seemed to be important in the transmission of the infection - faeces - flies - feed - and in many tropical countries they have open-si ...

Reducing dietary crude protein improves gut health in piglets

In high quality weaning feeds typically 10% whey is used, providing about 7% lactose. SFR considers that 10% of the lactose will be ileal undigestible and consequently will be fermented in the large intestine. Therefore the 10% whey will provide 0.7% fermentable carbohydrates (FCHO). The most significant sources of FCHO will be soybean meal in its different forms (Hipro SBM, full fat extruded soyb ...

Effects of dietary sulfur amino acid levels in broilers challenged with Eimeria spp

Hi Rose, I have conducted several experiments on "Amelioration of aflatoxicosis in poultry" involving various ameliorating agents including methionine and methionine hydroxy analogue. Based on a decade's long research on "Management of Mycotoxicosis in Poultry", I formulated two Toxin Binders, namely, Mycodetox B1 and Mycodetox B2. The efficacy of these two products was evaluated in Chickens, Turk ...

Quails as a model for chickens’ egg yolk color

Dear Syed Farjad Zaidi, I agree with your comment and, certainly, this is the aim of this work where modern layers were used in the trial in parallel to the quails. Preliminary results were presented at ESPN while we are preparing a full article to be published in the next months in a poultry journal.Thanks for your comment!

Important differences between soybean meal and full fat soy

"Soybean Meal" is produced by solvent extraction of the oil, typically in large scale plants (500 to 5,000+ MTD) that operate 24/7 so the processing conditions tend to be very stable. In the last stages of the extraction process the meal is desolventized and toasted to insure all of the hexane (solvent used to remove the oil) is recovered using both direct and indirect steam heating. The result is ...

Important differences between soybean meal and full fat soy

Mark Heimann Solvent extraction does exhibit variation from location to location, as you indicate yourself, and to the point that differences can be picked up when samples are taken from different plants and animal experiments performed.Mechanical methods are just like any other - as long as the process is understood and controlled, the variation between batches at an individual plant can be very ...

Distribution of trypsin inhibitor and urease activity in soy products in different countries and world areas

Dear Dr. Ruiz! I am very glad on reading your text. It is very clear and you were able to demonstrate your points based on literature review and long experience working in this field. This paper must be saved in all archives that discuss soybean meal quality, to be used, when needed. Thanks for all knowledge shared.
