The current concern of nutrient loading waterways and soils from livestock manure has increased awareness of methods to reduce excess nutrient excretion. The initial methods for nutrient reduction are simple diet manipulations to feed nearer the requirement of the pig. Further modifications have been made to increase digestibility of feedstuffs. The use of genetically modified corns and additio...

This experiment investigated the effect of feeding different levels of sesame oil cake on the intake and digestibility of DM, CP, crude fiber, and crude fat in Awassi fattening lambs. Sesame oil cake was incorporated into lamhs’ rafions at levels of 10 and 20% to replace similar percentages of barley and soybean. The results showed that the high level of sesame oil cake inclusion decreased DM a...

Poultry feathers, consisting largely of keratin, are a low-value product of the poultry industry. The safety and digestibility of a dietary protein produced from keratin (KER) was compared to a cysteine-supplemented casein-based diet in a growing rat model for four weeks. KER proved to be an effective substitute for casein at 50% of the total dietary protein, with no changes in the rats' food i...

Our primary objective was to determine the effects of abomasal infusion 16-carbon (16C) and 22-carbon (22C) fatty acids (FA) on apparent FA digestibility, plasma concentrations, their incorporation into milk fat in cows. secondary study 1-carbon donors choline l-serine these variables. Five rumen-cannulated Holstein cows (214 ± 4.9 d milk; 3.2 1.1 parity) were enrolled a 5 × Latin square experi...

The objectives were to quantify gastrointestinal tolerance, total tract nutrient digestibility, and serum lipid profiles of dogs as affected by α-cyclodextrin (ACD) supplementation and to validate the accuracy of fat analyses techniques using novel ACD-fat complexes. The ACD was hydrolyzed and free sugars and hydrolyzed monosaccharides were quantified using high performance liquid chromatograph...

BACKGROUND The nutritional quality of cassava complementary porridge was improved through extrusion cooking and compositing with either defatted or full fat soy flour (65:35 w/w), and product acceptability by mothers with children of the target population was evaluated. RESULTS The protein digestibility-corrected amino acid score (PDCAAS) of extrusion- and conventionally cooked composite porr...

Rats were fed for2 weeks on five different high-fat diets containing cellulose (control) or chitosan with and without organic acids (i.e., ascorbic, lactic and citric acids) as the dietary fiber. The apparent fat digestibility in the chitosanreceiving groups was significantly lower than in the control group. The addition of ascorbic acid to chitosan caused a larger increase in the fecal fat exc...

Metabolizable protein (MP) supply and amino acid balance were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources. Effects on production efficiency and N utilization of early post-partum dairy cows were determined. Forty-two multiparous and 16 primiparous Holstein cows were assigned to the diets in a randomized complete block design immediately after part...

The apparent digestibility coefficients of three protein levels of reference diets (without fish meal) and test diets (with fish meal) were estimated for Labeo rohita. Three test diets (test diet-I, test diet-II and test diet-III) and three reference diets (reference diet-I, reference diet-II and reference diet-III) having 28, 30 and 32% protein levels were prepared. Chromic oxide was used as a...
