A factorial experiment was conducted to assess nutrient utilization by growing lambs maintained on three levels each of digestible energy (high: HE, medium: ME, low: LE) and protein (high: HP, medium: MP, low: LP) in nine combinations (HEHP, HEMP, HELP, MEHP, MEMP, MELP, LEHP, LEMP, LELP). The experiment was conducted during the hot season in a semiarid location. Daily dry matter intake (DMI) w...

The aim of the study was to evaluate the supplementation of active yeast (Saccharomyces cerevisiae) on diets of lambs fed with two different concentrate proportion on DM intake, apparent digestibility of nutrients, in vitro digestibility of dry matter and rumen fermentation parameters. Twenty non-castrated male lambs, averaging 120 days-old, housed in metabolism cages, with collector and separa...

This study aimed to assess the growth performance and nutritional status of sheep under intermittent water supply by means performance, intake, apparent digestibility nutrients, balance nitrogen. Thirty-two intact male (20.7 ± 2.63 kg, 8 months age) were distributed in a completely randomized design with 4 intervals via drinking trough (0h00, 24h00, 48h00, 72h00), replicates. The extension rest...

The objective was to determine the values of apparent metabolizable energy (AME) and corrected for nitrogen balance (AMEn) roasted in natura amaranth grains. A breeding stock 108 female Japanese quails (Coturnix coturnix japonica) with an initial age 29 days used. birds were distributed a completely randomized design three treatments six replications, per experimental unit. used reference diet,...

This study was designed to determine the effect of physical form and urea treatment of rice straw on rumen fermentation, microbial protein synthesis and nutrient digestibility. Four rumen-fistulated dairy steers were randomly assigned according to a 2 (2 factorial arrangement in a 4 (4 Latin square design to receive four dietary treatments. Factor A was roughage source: untreated rice straw (RS...

Twelve ileal cannulated pigs (30.9 ± 2.7 kg) were used to determine the apparent (AID) and standardized (SID) ileal digestibility of amino acids in canola meals derived from black(BNB) and yellow-seeded (BNY) Brassica napus canola and yellow-seeded Brassica juncea (BJY). The meals were produced using the conventional prepress solvent extraction process (regular meals) or a vacuum-assisted cold ...

Four ruminally cannulated wethers (31+/-1.3kg) were used in an experiment with a 4x4 Latin square design to estimate the DM intake, apparent digestibility, nitrogen balance, rumen ammonia and microbial protein production. The sheep had ad libitum access to either Cassia rotundifolia (Cassia), Lablab purpureus (Lablab), Macroptilium atropurpureum (Siratro) or Stylosanthes guianensis (Stylo). Dry...

Utilization and requirement of egg protein in Japanese women with two levels of energy intake were estimated. In experiment 1, fifteen female students were given semi-purified diet containing whole egg as the sole nitrogen source for 12 days. Nitrogen intakes were 50 for five, 75 for two and 100 mg N/kg for eight subjects. Habitual energy intake was determined individually by detailed inquiry a...

the study was conducted to compare the effects of feeding acacia auriculata (aa), gmelina arborea (ga), albizia lebbeck (al) and butryospermum parkii (bp) tree forages as a sole feed for nigerian goats. four goats (yankasa) averaging one year and weighing 11.7±1.8 kg were used to measure the feed intake, digestibility and nitrogen balance. the leaves were offered ad libitum. dry matter (dm) int...

in the first experiment, the nitrogen corrected apparent metabolizable energy (amen) and nutrients apparent digestibility of full fat soybean (ffsb) extruded at 145, 155 (common temperature) and 165 o c were evaluated. the corn-soy based diets were replaced with zero, 7.5, 15 and 22.5 % of each ffsb extruded at three temperatures during 15-21 d of age and amen and nutrients digestibility of eff...
