The study set out to examine the effects of supplementing grass silage with various levels of protein concentration and degradability on dietary nitrogen (N) excretion in lactating dairy cows consuming at least 60% forage. Six Holstein/Friesian cows in early to midlactation were offered six diets comprising two levels of crude protein (210 and 290 g/kg DM) and three levels of protein degradabil...

The effects of inclusion of cellulose or inulin as a source of dietary fiber and CP content of the diet on hepatic fat deposition were investigated in hens fed restricted or close to ad libitum consumption. There were 12 dietary treatments forming a 2 × 3 × 2 factorial with 2 feeding regimens [restricted and liberal (close to ad libitum consumption; LIB)], 3 fiber sources (control, 3% inulin, a...

The objective of this experiment was to determine whether the digestibility of CP and AA in a mixed diet fed to growing pigs is better predicted when based on standardized ileal digestibility coefficients (SID) or apparent ileal digestibility coefficients (AID). Eight growing pigs (initial BW = 92.1 +/- 3.19 kg) were surgically equipped with a T-cannula in the distal ileum and arranged in an 8 ...

This study investigated the effects of replacing soybean meal (SM) with canola meal (CM) and decreasing crude protein (‎CP) levels in CM based diets on performance of dairy cows when different sources of processed grains and CM were used. Canola meal was untreated or roasted at 130°C for 30 minutes and grains sources (corn and barley) were either ground or steamed-flaked. Eight Holstein cows (‎...

Low protein diets are commonly used in the growing-finishing pig stage of swine production; however, effects low dietary on intestinal microbiota and their metabolites, association with sex, remain unclear. The present study aimed to assess impact a crude (CP) diet gut microbiome metabolome, reveal any relationship sex. Barrows gilts (both n = 24; initial body 68.33 ± 0.881 kg) were allocated i...

The purpose of this experiment was to evaluate the effects a low-protein diet on selected variables protein and energy metabolism in blood serum as well indicators fermentation faeces (fecal crude protein, ammonia, pH, volatile fatty acids, dry matter). Twelve finishing pigs (initial body weight: 64.6 ± 3.35 kg) were randomly divided into two groups fed basal diets with (CP) levels 13.6% 15.4%,...

The effects of dietary level of lysine and of level and source of CP on voluntary feed intake, growth performance, plasma free amino acids, and carcass characteristics were investigated in a study involving 60 female and 60 castrated male Large White finishing pigs (from 42 to 101 kg live weight) with ad libitum access to feed. Six treatments were compared according to a 2 x 3 factorial plan, w...

background: increase in aquatic production is dependent on raw materials, quality of diet, feed manufacture technology and optimum feed formulation. objectives: the aim of this study was investigation and quality control feed of fft, gft1 and gft2 of rainbow trout in farm and fish feed factory producers in chaharmahal and bakhtiari province. methods: in this study samples of fft, gft1 and gft2 ...

This study was carried out to investigate the effects of dietary putrescine (PUT) on broiler's response fed low crude protein (CP) diets. A total of 192 male day old chicks were fed with four dietary treatments including two levels of PUT (0 and 0.03%) and two levels of CP (normal and low) with factorial combinations. Weekly growth performance, nutrient digestibility and intestinal morphology (...

We evaluated the effect of cacao procyanidins (CP) on plasma lipid levels in high cholesterol-fed rats. Animals were divided into 4 groups, and each group was fed on either a normal diet, high cholesterol diet (HCD) containing 1% cholesterol (HCD without CP), HCD with 0.5% (HCD with 0.5% CP) or 1.0% CP (HCD with 1.0% CP) for 4 weeks. Plasma cholesterol level was significantly higher in the HCD ...
