Eight lactating cows were fed 4 diets in which dietary crude protein (CP) was increased steps of approximately 2 percentage units from 11 to 17% DM by replacing high-moisture corn with soybean meal supplemented rumen-protected Met maintain a Lys:Met ratio 3:1 metabolizable protein. Trial design replicated × Latin square; experimental periods lasted 28 d, data and sample collection being perform...

Objective: The objective of this study was to determine the effects sour yogurt addition on fermentation, aerobic stability, and in vitro digestibility corn silages.
 Materials Methods: research material consisted harvested October yogurt. experimental groups included control without added, 10 g (Y10), 20 (Y20), 30 (Y30), 40 (Y40), 50 added 1 kg fresh corn.
 Results: It found that amo...

Low-crude protein, amino acid-supplemented diets containing ractopamine balanced to contain 4.57 to 5.2 g of 1ysinelMcal of net energy can adequately supply amino acids for growth in late finishing pigs. Summary An experiment was conducted to determine the optimum lysine (lys):Net energy (NE) ratio of low-crude protein (CP) amino acid (AA)-supplemented diets needed in cor~jt~nction with racto-p...

The study aimed to evaluate the potential use of dried or ensiled paulownia (Paulownia spp.) leaves as roughage source for ruminants. Paulownia tree were collected from one-year-old hybrid (C-125, CAR, and TF-33 clones) trees. Dried clones different in dry matter (DM), crude ash (CA), protein (CP), ether extract (EE), fiber (CF), nitrogen-free (NfE) similar neutral detergent (NDF), acid (ADF), ...

A study was conducted to determine the influence of dietary energy and protein concentrations on growth performance and carcass traits of Pekin ducks from 15 to 35 d of age. In experiment 1, 14-d-old ducks were randomly assigned to 3 dietary metabolizable energy (11.8, 12.8, and 13.8 MJ/kg) and 3 crude protein concentrations (15, 17, and 19%) in a 3×3 factorial arrangement (6 replicate pens; 66...

The aim of the experiment was to assess an effect rainfall, temperature and fertilization on grassland dry matter (DM) production quality. Five treatments control (C0N), PK, N50PK, N100PK N150PK were established in western part “Zvolenská kotlina” basin (Slovakia) alluvial meadow. paper consists experimental data collected during 11 years (2008 – 2018). highest DM found treatment with rate 150 ...

Two experiments were conducted to evaluate the effect of stocking density on growing-meat quail performance (experiment I) and the effect of dietary crude protein (CP) levels and stocking density on growth performance, nutrient retention, blood metabolites, and carcass weight of growing-meat quails under high ambient temperature (experiment II). Three hundred and eighty male growing-meat quails...

The effect of inclusion level on nutrient intake, digestibility, nitrogen metabolism and haematological parameters of West African Dwarf (WAD) goat fed Cajanus cajan as supplement to cassava peels was investigated in a completely randomized design experiment using twenty-four WAD goats with average initial weight of 10.75±0.85kg (March-September, 2016). There were four treatments as: A...

The aim of this study was to determine the chemical composition and in vitro digestibility, and to estimate the in vitro fermentation parameters of palm leaves and pedicels from Ghars palm variety. A rumen in situ technique was also used to examine In vitro Digestible Dry Matter (IDDM), In vitro Digestible Crude Protein (IDCP), and In vitro Digestible Neutral Fiber (IDNF), and rate and extent o...

Dueto theactionofo-quinones formedviapolyphenoloxidase, conserved red clover (Trifolium pratense L.) contains abundant rumen undegradable protein (RUP), but inadequate rumen degradable protein (RDP) fordairy cattle. This studyexaminedhowforagemanagement influences RDP, RUP, crude protein (CP) and fiber fractions in red clover silage and dry matter (DM) yields during the first full production ye...
