While corn contains only limited quantities of crude protein and amino acids, corn by-products often contain crude protein and amino acids in appreciable amounts. The reason for this difference is that corn by-products are often produced after processing that primarily removes the nitrogen-free extracts (i.e., the starch) from the corn kernel. Because starch is approximately 70% of the total co...

the chemical composition, in situ ruminal degradability coefficients of dry matter (dm), and nutrient digestibility in sheep were evaluated for corn silage (cs) treated (fresh weight basis) with different levels of a commercial bacterial inoculant (i) as follows: (1) untreated cs (control); (2) cs + i at half of the recommended level; (3) cs + i at the recommended level (3  1010 colony forming...

Measurements were made on protein sup,plcments in.a basal diet, of dry matter, nitrogen and amino acid digestibilities using mature and' adult cockerels. Birds were killed 5h after receiving their diet in a single feed. Analyses were made on digesta from (i) the ileum, (ii) the terminal ileum, (iii) post caeca, and on excreta. In a second exDeriment -adult cockerels were fitted with a sitiple c...

A series of experiments was designed to evaluate inert markers employed in studies of ileal and faecal apparent digestibilities of nitrogen and amino acids in pigs fitted with simple 'T' piece cannulas. Trial 1 assessed the palatability of diets containing (a) 5 g chromic oxide/kg, (b) 1 and (c) 5 g titanium dioxide/kg at two levels of feeding. The results indicated that there were slight probl...

The present study was carried out to determine the ileal digestibility of Arg and Lys in acutely heat-stressed broilers using diets varying in Arg:Lys ratio, NaCl concentration, and Met Source. Male broilers were maintained at 22 degrees C from 21 to 33 d of age and then at 32 degrees C from 33 to 38 d of age. From 28 to 38 d of age, birds were fed a diet with an Arg:Lys ratio of 1.05 and 3 g o...

Protein quality is related to amino acid composition and digestibility. Accurate evaluation of apparent digestibility coefficients (ADCs) nutrients in commonly used feedstuffs paramount for formulating efficient aquafeed. ADCs soybean meal (SBM) poultry by-product (PBM) were evaluated using reference diets formulated with two types ingredients (semi-purified [SP] practical [P]) juvenile Nile ti...

Raw or germinated faba bean (Vicia faba minor var. Alameda) and chickpea (Cicer arietinum kabuli var. Athenas) seed meals were incorporated in essential amino acid-supplemented and energy-equalized diets for growing (65 (SD 1) g) male Wistar rats as the only sources of dietary protein. A lactalbumin-based diet was used as the control. Faecal dry weight and N excretion of animals fed legume-cont...

This study investigated the nutritional quality of soybean meal (SBM) fermented by Aspergillus (FSBMA) and/or followed by Lactobacillus fermentation (FSBMA+L). Both fermented products significantly improved protein utilization of SBM with higher trichloroacetic acid (TCA) soluble true protein content, in vitro protein digestibility and available lysine content, especially in FSBMA+L. Moreover, ...
