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...
This study determined the apparent and standardized ileal amino acids digestibility (AID or SID) for growing pigs fed three protein feedstuffs with different fiber types at two dietary crude protein (CP) levels. Twenty boars (Yorkshire × Landrace) with 35 kg body weight and fitted with a simple T-cannula at the distal ileum were used. The treatments were three protein feedstuffs [soybean meal (...
An experiment involving 25 experiment stations in the North Central and Southern regions (NCR-42 and S-288, respectively) was conducted to assess the degree of uniformity of diet mixing among stations and to assess the variability among station laboratories in chemical analysis of mixed diets. A fortified corn-soybean meal diet was mixed at each station using a common diet formula (except for v...
This study was conducted to determine the effect of daily recombinant porcine somatotropin (rpST) injection (0 or 120 pg/kg BW) and dietary CP level of the feed (14 or 26% CP) on pancreatic characteristics of growing pigs. Daily injection of rpST did not affect pancreatic weight ( P = .885) but did decrease pancreatic amylase content ( P = .005). The ratios of amy1ase:protein and amy1ase:trypsi...
Barley (Hordeum vulgare) and wheat (Triticum aestivum) are often stored dry with 14% or less moisture, which during rainy periods may require that grains are dried after harvest. The hypothesis is that air-tight storage of high-moisture barley and wheat will increase nutrient digestibility due to chemical conversions prior to feeding. The objective was to evaluate the effect of high moisture co...
A study was conducted to evaluate the effects of adding all essential amino acids (EAA) equal to that of higher CP diets or a mixture of nonessential amino acids (NEAA) to low CP diets on the live performance of broilers during the period of 0 to 21 d. A series of experimental diets comprised primarily of corn and soybean meal were formulated to contain 3,200 ME kcal/kg. Five primary diets were...
Pigs fed protein-bound AA appear to have a higher abundance of AA transporters for their absorption in the jejunum compared with the duodenum. However, there is limited data about the effect of dietary free AA, readily available in the duodenum, on the duodenal abundance of AA transporters and its impact on pig performance. Forty-eight pigs (24.3 kg initial BW) distributed in 4 treatments were ...
Background: Nutrient restriction is a common strategy to prevent metabolic disorders in fast growing broiler chickens, but limited information available regarding the impact of diets with low protein and energy on leg abnormalities. Objective: Two experiments were conducted evaluate effect varying crude (CP) metabolizable (ME) levels gastrocnemius tendon (GTeBS) tibia breaking strength (TiBS), ...
The present study aimed to investigate the nutritional aspects of the bear diet quantitatively, in order to understand plant food selection in spring. Bears were observed directly from April to July in 2013 and 2014, to visually recognize plant species consumed by bears, and to describe the foraging period in the Ashio-Nikko Mountains, central Japan. Leaves were collected from eight dominant tr...
An experiment was conducted to evaluate the effect lysine and methionine supplementation low protein diet on production performance serum biochemical parameters in Vanaraja laying hens. One hundred twenty (n=120), 30-weeks old hens were randomly distributed into four dietary treatments with three replicates each group having 10 birds replicate. Four diets formulated 2600 kcal/kg of metabolizabl...
