Metabolizable protein (MP) supply and amino acid balance in the intestine were manipulated through selection of highly digestible rumen-undegradable protein (RUP) sources and protected methionine (Met) supplementation. Four ruminallycannulated, multiparous Holstein cows averaging 193±13 days in milk were used in a 4×4 Latin square design to assess N utilization and milk production responses to ...

This experiment was carried out to investigate the effects of different level of dicalcium phosphate on growth, digestibility, rumen fermentation and some blood parameters. Eighteen growing local breed male lambs (about 3 months old) with an average weight of 23.61 ±0.58 Kg were divided randomly into three feeding groups for 150 days, fed on: Ration one ( R1) : CFM contained1% dicalcium phospha...

Diploid and triploid Atlantic salmon, Salmo salar were fed high-protein, phosphorus-rich diets (56-60% protein; ca 18g phosphorus kg-1 diet) whilst being reared at low temperature from start-feeding until parr-smolt transformation. Performances of salmon fed diets based on fish meal (STD) or a mix of fishmeal and hydrolysed fish proteins (HFM) as the major protein sources were compared in terms...

An experiment was conducted to evaluate the influence of different Ca sources (limestone, Ca chloride, and Lipocal, a fat-encapsulated tricalcium phosphate, TCP) in conjunction with 4 dietary levels of non-phytate P (NPP) on performance, ileal digestibility of Ca and P, and bone mineralization in broiler chickens. Calcium sources were also evaluated in vitro to measure acid-binding capacity (AB...

Twelve Nili-Ravi buffalo calves of age between 8-10 month and average body weight 112 ± 3.30 kg were randomly divided into three treatments (4 calves per treatment). Three isonitrogenous (16.14% CP) and isocaloric (66% TDN) dietary treatments: A) Calcium (Ca) 0.46% + Phosphorus (P) 0.31%; B) Ca 0.59% + P 0.31% and C) Ca 0.75% + P 0.31% on dry matter basis with Ca : P ratios of 1.5:1, 2:1 and 2....

Problem statement: There is evidence that the addition of 3% STA-LITE polydextrose to a dry food reduces clinical signs of osteoarthritis in dogs. For the application of polydextrose as functional ingredient of dog foods, information as to its impact on the acceptance of food, feces consistency, fecal odor and digestibility of macronutrients and minerals is required. Approach: A feeding experim...

OBJECTIVE This study investigated the effect of microbial phytase supplementation on growth performance, tibia ash, plasma parameters, apparent ileal digestibility (AID) of amino acid (AA) and apparent digestibility of nutrients in Youxian Sheldrakes fed with low-phosphorus (P) corn-soybean diets. METHODS A total of 350 Youxian Sheldrakes (7d old) were randomly divided into 5 treatment groups...

Phosphorus (P) is a macro mineral in broiler nutrition. In growing broilers, besides its requirement for proper bone development, it is also involved in almost all metabolic processes. Poor P availability results in decreased productivity and poor health status.Phosphorus availability from plant derived feeds is affected by an anti-nutritional factor “phytate”, which forms a variety of insolubl...
