Effects of synchronizing the availability of amino acids and glucose within a day on protein and energy metabolism were studied in heavy preruminant calves. Thirty-six preruminant calves (148 +/- 1.6 kg body weight) were assigned to 1 of 6 degrees of nutrient synchrony (SYN, 1-6) and to 1 of 2 meal sequences (i.e., the high-protein meal in the morning or in the evening). Calves at SYN 1 receive...

First-year alligators (Alligator mississippiensis) averaging 377-857 g body weight were fed diets containing various levels of protein, fat and carbohydrate. In experiment 1, nine diets arranged in a centrally rotatable composite design contained 0-36% extruded corn and 4-20% total fat. Response surface analysis predicted maximum responses in performance criteria at 6.3-18.8% corn and 15.8-27.4...

In in vitro true dry matter degradability (IVTDMD), in situ dry matter degradability, and neutral detergent fiber degradability, both in vitro (IVNDFD) and in situ (ISNDFD) techniques were used with crossbred goats to determine dry matter and neutral detergent fiber (NDF) ruminal degradability in eight forages and four industrial byproducts. Total digestible nutrients (TDN) content obtained wit...

A 60-days feeding trail was conducted to evaluate the effects of dietary digestible energy levels (DE) on kutum, Rutilus frisii kutum. Four is nitrogenous (35% protein) diets with digestible energy levels of 2500, 2600, 2700 and 2800kcal kg-1 was tested. Two hundred and forty advanced fry (2±0.4g) were randomly distributed in 12 fiberglass tanks of 400L capacity. Nutritional responses in...

The scientific literature is exploding in quantity even as it stands still in literary quality. In this brief guide, I suggest a few small steps that the individual can take to make his or her writing clear, straightforward, and digestible.

The traps of Byblis gigantea are active, because after capturing a digestible particle (prey) it changes its position so that rests on the surface with digestive glands.

an in vitro experiment was conducted to determine the effect of supplemental non-fiber carbohydrate(nfc) on the disappearance kinetics of cellulose (ce) by mixed ruminal microorganisms. non-supplementedor nfc supplemented cellulose (467 mg nfc/g cellulose as sucrose (cesu) or starch (cest) or a 1:1 mixtureof sucrose + starch (cesust)) were incubated for 24, 48, and 96 h at 39°c. after each incu...

introduction: nutrition and health during the first days of life has critical effect on broiler chickens performance. it is well known that diet formulation based on digestible nutrients is superior to formulation based on total nutrients. the suitable supply of essential amino acids in broilers’ diets requires proper knowledge on their metabolic effects in the body. the excessive or unbalanced...

Six experiments were conducted to validate the hypothesis that Lys and SAA requirements decrease within starter phase using 3-day periods from 2 11 d of age. In first 3 experiments, 7 diets generated by adding L-Lys a lysine deficient basal diet in 0.10% increments, ranging 0.85 1.45% Digestible Lys. Experiments 4 6, 0.07% increments DL-methionine produce 0.63 1.04% DSAA. The linear broken line...
