Several strategies are being developed to minimize nitrogen (N) pollution from poultry waste in areas with high concentrations of commercial poultry operations. This study focus on the effect of feeding reduced protein (CP) diets on laying hens housed under commercial conditions. The experiment was carried out using 144 Hy-Line W-36 hens which were randomly assigned to one of four dietary treat...

Processing green biomass into novel products provides opportunities to improve the sustainability of bioeconomy. The objective this study was evaluate effects types (fresh, frozen-and-thawed, dried-and-rehydrated and ensiled grass) as well formic propionic acid-based additive on efficiency liquid-solid separation crude protein (CP) yield. Three different pressing methods for were used. All pres...

This study evaluates low protein diets with amino acid supplement on growth, biochemical markers and muscle acids profile in broilers under high ambient temperature. A total of 480 one-day-old chicks were allocated into three treatments four replicates (n = 40). Control fed optimal which contains 23% 21% crude (CP) 65% methionine + cysteine/ lysine (Met Cys/Lys) 55% threonine/lysine (Thr/Lys), ...

Current ruminant feeding systems depend on knowledge of the composition of feeds and the rate and extent of degradation of feed organic matter (OM) and crude protein (CP) in the rumen. The effect of storage and preparation of samples on in vitro gas production and fermentation characteristics of two common forage species, namely alfalfa and ryegrass werestudied. Samples were prepared as fresh (...

Maize silage (MS) has become one of the major energy components in ruminant nutrition. The maize crop is suitable for ensiling and high dry matter (DM) yield nutritive value. aim this review to provide a comprehensive overview effect cutting height maturity at harvest on chemical composition MS fermentation quality silo. With an increase maturity, content increases about 400 g DM/kg fresh crop,...

Racing pigeons are exposed to and act as carriers of diseases. Dietary protein requirement for their maintenance has not been determined experimentally despite their being domesticated for over 7000 years. A maintenance nitrogen (protein) requirement (MNR) for pigeons was determined in a balance study using diets containing 6, 10 and 14% crude protein (CP). Then, the effects of feeding the diet...

In the present study, a linear regression analysis between lysine intake and lysine retention was conducted to investigate the efficiency of lysine utilisation (k(Lys)) at marginal lysine intake of either protein-bound or free lysine sources in juvenile turbot (Psetta maxima). For this purpose, nine isonitrogenous and isoenergetic diets were formulated to contain 2·25-4·12 g lysine/100 g crude ...

Two experiments were conducted to determine U.S. soybean meal (SBM) variation. In experiment 1, SBM from 55 U.S. processors was evaluated. Significant (P < 0.05) but numerically small differences were detected in dry matter (DM) and organic matter (OM) concentrations. Crude protein (CP) concentrations (51.6-54.6%) were higher (P < 0.05) in SBM produced in the southern U.S. Lipid and total dieta...

The objective of this study was to evaluate the intake and digestibility nutrients, emission enteric CH4, productive performance Nellore bulls grazing Urochloa brizantha cv. Marandu palisade grass pastures during rainy season, receiving an energy supplement or mineral supplement, with without inclusion phytogenic additives. Forty-eight were treated with: (1) additives; (2) (3) (4) Consumption t...
