Adult mallard ducks and northern bobwhite quail were exposed to 0, 10, 50, or 150mg perfluorooctane sulfonate (PFOS)/kg in the diet for up to 21 weeks. Adult health, body and liver weight, feed consumption, gross morphology and histology of body organs, and reproduction were examined. Due to mortality, birds exposed to 50 or 150mg PFOS/kg feed were terminated by Week 7. In quail, the lowest obs...

Aim: To evaluate the effect of different levels of High Bentonite on growth performance, organ weight and serum biochemistry in broiler fed on diets containing aflatoxin. Materials and Methods: A total of 360 day-old commercial broiler chicks were divided at random into 8 dietary treatment groups of 42 chicks each having 3 replicates. Dietary levels of aflatoxin (0.5 ppm) and High-grade bentoni...

Environmental stress boosts the levels of stress hormones and accelerates energy expenditure which subsequently imbalance the body's homeostasis. L-ascorbic acid (L-AA) has been recognized to mitigate the negative impact of environmental stress on production performances in birds. The present investigation was carried out to elucidate the effect of different dietary levels of L-AA on production...

AIM The objective of this study was to evaluate the effect of feeding fermented fish silage (FFS) on serum biochemical parameters of Japanese quails (Coturnix coturnix japonica). MATERIALS AND METHODS A total of 192, 7-day-old broiler Japanese quail chicks of either sex, were randomly distributed into four dietary treatments with four replicates in each group having 12 chicks in each replicat...

Paralytic shellfish poisoning (PSP) is a public health risk worldwide, resulting from the consumption of seafood that has bioaccumulated toxins produced by microalgae.1 Bivalve shellfish (such as mussels, clams, oysters and scallops) pose a particularly high risk as they feed by filtration, providing a method of toxin accumulation. Algae responsible for causing PSP include several species of th...

An experiment was carried out to determine the effect of dietary protein level on the specific activity of hepatic L-threonine dehydrogenase in young growing chicks. Six replicate pens of seven Leghorn chicks were fed semipurified diets containing 23, 27, or 32% CP with identical relative proportions of amino acids in each protein group. Body weights and feed consumption were measured for 3 d, ...

an in vivo experiment was conducted to determine the effect of dietary betaine supplementation (betafin®) as a replacement for methionine on broiler performance and carcass characteristics. in a completely randomized design (crd) with five treatments of betaine levels (at 0, 25, 50, 75, and 100% in replacement for methionine) and five replicates of 10 birds/replicate, two hundred fifty-day-...

Dried sphagnum moss was ground using a pin mill and hammer under various operating conditions, i.e., changes in the rotor frequency feed rate. The specific energy consumption of size reduction recorded. powder characterized by median particle size, width distribution (span), loose tapped bulk densities, Hausner ratio. Pin milling used less for than milling, especially when target below 100 μm. ...

Thirty-six lactating Alpine does were used to determine effects of stage of lactation and level of feed intake on energy utilization. Twelve does were assigned to measurement periods in early, mid, and late lactation (wk 5, 13, and 27, respectively). For 6 does of each group, after ad libitum consumption of a 60% concentrate diet, feed intake was restricted to near the metabolizable energy (ME)...
