TL;DR: The Cornell Net Carbohydrate Protein Model (Chalupa et al., 1991) has developed the need for uniform procedures to partition feed nitrogen into A, B, and C fractions (Pichard and Van Soest, 1977) as mentioned in this paper.

TL;DR: In this article, a method was developed to determine the concentration of titanium dioxide in poultry digesta samples, obtained from the lower half of the small intestine of three-week-old male broiler chickens.

TL;DR: In this article, Moringa oleifera leaves were extracted and unextracted from aqueous ethanol and the true protein contents of these leaves were 93.8% and 81.1% respectively.

TL;DR: As animal production continues to improve through genetic gain, the need for high quality forages will become more important and there is good potential for producing new cultivars with improved forage quality and several are now on the market.

TL;DR: In this paper, a flexible, empirical, multiphasic model was proposed for parameterization of gas production profiles and the maximum fractional rate of substrate digestion (RM) was calculated for each phase.

TL;DR: In this paper, a new fully automated time related gas production apparatus is presented to study fermentation kinetics in rumen fluid, which makes use of electronic pressure transducers in combination with electric valves to release overpressure during the incubation.

TL;DR: An overview is given on the binding mechanisms in pelleted animal feeds and it is concluded that binding in pellets most probably is due to solubilisation and subsequent crystallisation of feedstuff components e.g. starch, sugars, fats or ‘liquid necking.

TL;DR: Innovative research on reducing or mitigating the negative qualities of alternate protein sources is increasing the potential for their use in fish feeds and will help alleviate future demands for fish meal by the aquaculture industry.

TL;DR: The fatty acid composition of oilseeds such as canola are considered desirable from a human health perspective and thus their inclusion in the diet of dairy cattle as a means of achieving a more desirable fatty acid profile in milk fat may enhance the nutritive quality of milk.

TL;DR: This paper defines the various types (complexes, amino acid chelates and proteinates) of organic trace minerals commercially available and reviews research regarding their bioavailability and effects on physiological responses in ruminants.

TL;DR: As a low cost insurance to provide adequate mineral nutrition, a modified ‘complete’ mineral supplement should be available free-choice and need to be evaluated for accuracy of formulation and suitability for cattle.

TL;DR: It appears that supplementation of 500 IU vitamin E per head daily for 84–126 days yields tissue α-tocopherol that would maintain a favorable level of oxymyoglobin in meat, thus increasing its value.

TL;DR: In some cases, changes in feed processing technology will be dictated, not by animal response, but by other motivations such as regulatory guidelines or human health concerns as mentioned in this paper, and a case in point is the use of hydro-thermal processes such as pelleting, extrusion, or roasting to reduce the microbiological load in the feed.

TL;DR: Cereal grain starch utilization by poultry is affected by the grain species and grain sample within a species, which impede digestion of all nutrients including starch.

TL;DR: The stomach is the site of highest added microbial phytase activity most likely because of a more favorable pH and lower protease activity.

TL;DR: Performance of calves was not significantly affected by treatments, although body weight increased most during weeks 7–9 for calves fed the mixed lactobacilli and in weeks 10–12 for calves feeding L. acidophilus 27SC.

TL;DR: Results indicated that the gastrointestinal epithelium responded to oxidant stress with an increase in cell turnover and indicators of oxidative stress may be related to the poor performance seen in animals fed unstabilized diets containing oxidized ingredients.

TL;DR: In this article, a study of the Langmuir and Freundlich isotherms was carried out to evaluate the affinity and capacity of a feedstuff additive, a montmorillonite silicate, to adsorb the four major naturally occurring aflatoxins.

TL;DR: A compromised immune system will result in increased morbidity and mortality rates and thereby decrease animal production efficiency, and carotenoids and vitamins A, E and C are important to animal health by enhancing immunity.

TL;DR: While some carbohydrase enzyme preparations were shown to be effective in the in vitro test of cell wall polysaccharide solubilization, only a trend toward improved growth performance was noted when broiler chickens were fed semipurified canola meal diets containing these enzyme preparations.

TL;DR: Leucaena forage productivity indicated that the optimum harvesting interval or age at harvest should be about 8 weeks or just before the onset of flowering, and a model developed in one source suggested 42% rumen degradable protein (RDP), with 48% of the undegradableprotein (UDP) being digested post ruminally, giving a TADCP value of 70%.

TL;DR: Substances that prevent microbial attachment or promote detachment can be used to regulate the rate of cereal grain digestion in the rumen and include an appreciation for the microbial processes involved in cerealgrain digestion.

TL;DR: There is a considerable range in the composition and nutritive value of peas, and concerns about low digestibilities relate to the sulphur amino acids and tryptophan.

TL;DR: Positive correlations between Lacto diets and nitrogen and calcium retention, and egg mass and between fat, nitrogen, calcium and phosphorus retention and body weight gain, calcium’s retention and eggmass, respectively, were observed.

TL;DR: In this article, specific body temperature regulatory mechanisms are discussed, as well as management considerations regarding facility design, fasting, management of water temperature and consumption, acid-base balance, acclimation and diet composition considerations.

TL;DR: In this article, two experiments were conducted to investigate the effects of steam processing on the nutritional improvement of full-fat soya beans, and the results showed that the level of functional lectins was most effectively inactivated by high temperature.

TL;DR: The results presented in this study clearly demonstrate that the use of tabulated values for describing individual batches of forages in terms of their degradability characteristics is inaccurate since they may not reflect the particular forage being used in the ration and thus may lead to errors in diet formulation.

TL;DR: It is concluded that halophytes could become important feed resources at moderate inclusion levels wherever production of these plants can be justified agronomically.

TL;DR: It is suggested that there is a simple relationship between the amount of enzyme added to the diet and the resulting improvements that are obtained, and enzymes when properly used can produce significant improvements in chick performance and can reduce the excretion of undigested nutrients.

TL;DR: In this article, the potential of NIRS to predict chemical composition and calculated protein values (digestible protein in the intestine and degraded protein balance) were investigated using partial least squares analysis.
