egg ω-3 content for the fl axseed diet (from 546 to 578 mg/60g egg; P=0.02) and for the Linpro diet (from 415 to 438 mg/60g egg; P=0.07). As well, an overall decrease (P=0.01) in ω-6 to ω-3 ratio (from 1.53 to 1.47) was noted. Enzyme addition increased (P=0.02) the NSP digestibility from 17.2 to 24.6%. There was no signifi cant effect of enzyme addition on total tract fat digestibility. Overall...

Two experiments were conducted to determine the effects of rancidity and FFA in choice white grease (CWG) on growth performance and nutrient digestibility in nursery pigs. In Exp. 1,150 crossbred pigs (average initial BW of 6.8 kg and average initial age of 21 d) were used. Treatments (as-fed basis) were a corn-soybean meal-based control with no added fat, 6% CWG, and 6% CWG heated at 80 degree...

The purpose of this study was to determine the effect fermented straw supplementation with green concentrate on nutrient content and digestibility. Green used as treatment white lead tree leaf flour ( Leucaena leucocephala ), Gamal meal Gliricidia sepium Indigofera meal. Proximate analysis carried out rice straw, 70% + 30% lamtoro (FRS tree), ) ). livestock for digestibility test 12 Friesian Ho...

The effects of dietary calcium (Ca) concentration on the digestion of Ca, phosphorus (P), nitrogen (N), fat and starch along the intestinal tract of broilers were assessed. Three-week old broilers were fed maize-soy diets containing 6, 9 or 12 g/kg of Ca (Ca: total P ratios of 1:1, 1.4:1 and 2:1, respectively) for six days and digesta were collected from the duodenum, jejunum, upper ileum and l...

A feeding trial was carried out to investigate the effects of lecithin on growth performance, nutrient digestibility, lipid profile, carcass characteristics and meat quality of broiler chickens. A total of 240 oneday- old male broiler chicks (Cobb 500) were obtained from a local hatchery and raised for 42 days. The chicks were divided into 5 dietary treatments. The diets supplemented with prill...

This experiment aims to study the effects of dietary fat level during suckling period on growth performance and meat characteristics in twin lambs. Thirty pairs male Hu lambs were divided into two groups, namely high (HF) normal (NF). Lambs HF group fed milk replacer starter containing 26.89% 5.07% fat, whereas those NF 15.15% 2.80% respectively, from eight 60 days age. From 120 age, all a feed...

the purpose of this study was to determine the effect of two levels of four commercial multi-enzymes on the apparent metabolizable energy corrected for nitrogen (amen) and digestibility of crude fat, crude protein, dry matter, and organic matter in broiler chickens through total excreta collection method. one hundred thirty male broiler chicks were assigned to 45 metabolic cages involving 9 tre...

A model system was established to evaluate the ability of a pancreatic lipase enzyme to hydrolyse fats and oils, simulating lipid digestion in vitro. Lipid hydrolysis was monitored by quantification of the level of free fatty acids, mono-, diand triglycerides. In the model system the pancreatic lipase was able to hydrolyse a non-oxidized fat quite rapidly. The activity of the lipase enzyme was ...

Four Holstein steers (261 +/- 2 kg) with cannulas in the rumen and proximal duodenum were used in a 4 x 4 Latin square experiment to evaluate the interaction of dietary Ca (.45 vs. 90%) and supplemental fat (0 vs 5% yellow grease) on characteristics of digestion. There were no treatment interactions (P > .10). Supplemental Ca did not influence (P > .10) digestibility of OM, NDF, starch, N, and ...

Fibre can interfere with digestibility of fat by accelerating intestinal passage or increasing chyme viscosity. Lecithin is an important emulsifier which improve digestion. The study aims to determine if fibre solubility may apparent true total tract (ATTD; TTTD) macronutrients and energy adding lecithin could digestibility. Stool quality was evaluated regarding inclusion. Eighteen adult dogs f...
