this research project was conducted to evaluate bioavailability and chemical properties of different zinc sources in broiler chickens when fed by practical diets. for that, 312 day-old male ross 308 broiler chicks were fed from 8-28 day to estimate the biological availability of four zinc sources. chicks were allocated randomly to 13 experimental diets in a 3 × 4 factorial design. diets include...

this experiment carried out to evaluate replacing effects of oyster shell (os) with filter cake (fc) of sugar beet industry on performance and quantity and quality of egg in  laying hens .in this trial the filter cake in two physical forms of powder and pellet in  five levels of 0, 25, 50, 75, and 100% replaced for oyster shell. each treatment had 3 replications. the experiment lasted 3 periods...

four west african dwarf (wad) grower bucks averaging 6 kg in weight and aged between 5-6 months of age were used in a digestive trial to determine the intake and digestibility of raw or processed pigeon pea seed meal based diets. the diets designated rpbd, spbd, tpbd and bpbd were formulated from cassava peel, palm kernel cake, brewers dry grain, bone meal and common salt to contain 15% of raw,...

four hundred fifty day old unsexed broiler chicks were used in a 35-day trial at chittagong veterinary and animal sciences university farm to find out the effect of using crude soybean oil sediment (csos) as a substitute for refined soybean oil (rso) in broiler diet. the experiment was carried out following completely randomized design. the chicks were randomly distributed in three treatment gr...

Heat stress and reduced feed intake negatively affect intestinal integrity and barrier function. Our objective was to compare ileum protein profiles of pigs subjected to 12 hours of HS, thermal neutral ad libitum feed intake, or pair-fed to heat stress feed intake under thermal neutral conditions (pair-fed thermal neutral). 2D-Differential In Gel Electrophoresis and gene expression were perform...

Experiment 1 consisted in the genetic selection of two divergent lines D+ and Don the basis of AMEn value measured at 3 weeks of age with birds being fed a wheat diet, using the wheat Rialto cultivar characterised by a high in-vitro viscosity value. Significant difference (3413 J/g DM; P< 0.0001) in AMEn between lines reached 29 % on 4 generation. From the experiment 2 consisting in the test of...

Results: Higher average daily lactation feed intake, greater litter weight, and greater backfat thickness at weaning were associated with less likelihood of removal of sows from the herd before the subsequent parity. Sows consuming ≤ 3.5 kg of feed per day during the fi rst 2 weeks of lactation were more likely to be removed from the herd before the next parity. Implications: Measures to ensure...

Four diets with different crude protein levels 17.75%, 19.95%, 21.85%, 24.08% were used to feed 192 seven-week-old yellow quails in this experiment. During 50-day-old to 95-day-old, laying rate, feed intake and egg weight were recorded to analysis the effect of different levels of dietary protein on the performance of yellow quails. All fences were collected and analysis the effect of different...

An experiment was conducted that examined the effect of day-to-day variability of dietary energy on feed intake behavior. Three levels of average daily dietary ME composition (2,580, 2,814, and 3,009 kcal/kg) and three levels of day-to-day variability of ME (low, medium, and high) were assigned to nine groups of DeKalb-XL laying hens in a 3x3 factorial design. Each of the nine treatments contai...
