Whiteleg shrimp, Litopenaeus vannamei is one of the most commercially farmed species worldwide because of its fast growth, good survival rate at high farming densities, and osmoregulatory capacity, which makes it an excellent candidate for cultures at different salinities. The knowledge of shrimp nutritional requirements is critical in the formulation of diets to allow optimal growth at differe...

An experiment was conducted to determine apparent ileal digestibility of crude protein (CP) and amino acids (AA) and digestible CP and AA of fish meal (FM) in 21-d-old broiler chickens using the regression technique. Four diets containing 0, 1, 2, and 3% FM in place of cornstarch were formulated with FM as the sole contributor of CP and AAs in the sequential diets. Eighty 14-d-old broiler chick...

Eighty, 12-day-old, male broiler chicks, were fed one of four diets to determine the effects of feeding grains varying in phytate phosphorus (P) and intrinsic phytase activity on ileal and excreta P digestibility and composition. The diets contained approximately 970.7 g grain kg−1 (maize, high fat–low lignin oat, normal barley or low-phytate barley) with the cereal supplying the sole source of...

Five sources of corn distillers dried grains with solubles (DDGS), which varied in darkness of color, were collected from several processing plants in the Midwestern United States. Sources of DDGS were analyzed for their amino acid and energy contents, measured for color score, and evaluated for TMEn, apparent amino acid digestibility, and true amino acid digestibility. A precision-fed rooster ...

A total of 50 weaning pigs (16 d of age; 4.72 +/- 0.23 kg of BW) were selected to investigate the effect of dietary chito-oligosaccharide (COS) supplementation on growth performance, fecal shedding of Escherichia coli and Lactobacillus, apparent digestibility, and small intestinal morphology. Pigs housed in individual metabolic cages were assigned randomly to 5 treatments (n = 10), including 1 ...

This study was designed to evaluate dry matter intake (DMI), ruminal fermentation, digesta outflow, omasal flow of N constituents, and total-tract digestibility in response increasing dietary lipid content derived from high-lipid by-product-based pellets for finishing beef cattle. Five ruminally cannulated heifers were used a 5 × Latin square design. Dietary treatments iso-nitrogenous with ethe...

Our objective was to evaluate raw meat diets for captive exotic and domestic carnivores containing traditional and alternative raw meat sources, specifically, beef trimmings, bison trimmings, elk muscle meat, and horse trimmings. We aimed to examine diet composition and protein quality; apparent total tract energy and macronutrient digestibility in domestic cats, African wildcats, jaguars, and ...

18 Producing organic fish diets requires that the use of both fish meal and fish oil is minimized 19 and replaced by sustainable, organic sources. The purpose of the present study was to 20 replace fish oil with organic oils and evaluate the effects on feed intake, feed conversion 21 ratio (FCR), daily specific growth rate (SGR) and nutrient digestibility in diets in which fish 22 meal protein ...

Thirty eight veal calves aged 7 weeks were fed milk replacers containing either coconut fat or tallow for a period of 15 weeks. Body weight gain was 114.2 10.3 and 115.7 22.5 kg (mean SD, n = 19, P > 0.05) for the calves fed the diets with either coconut fat or tallow, respectively. Faeces were collected during the last week of the trial. Apparent digestibility of crude fat was 93.3 4.9 and 91....
