  The present investigation was carried out to examine the presence of Booroola FecB mutation gene in 124 selected prolific ewes from 6 flocks representing two Saudi Arabian local sheep breeds by forced PCR-RFLP method. Genomic DNA was extracted from the blood of 69 Najdi and 55 Naeimi matured ewes with litter size varied from 2.01-2.16 lambs per ewe lambing. Digestion of FecB gene 190 base pair with AvaII restriction enzyme resulted in non carrier 190 bp band wild type in all samples which revealed the absence of this mutation in the tested Najdi and Naeimi sheep breeds.

  An experiment was carried out to evaluate the effects of replacing corn with extruded Bakery Waste (BWP) in a corn-soybean basal diet during the starter and finisher periods (day to 21 and 22-35 days of age, respectively) on the performance (weight gain, feed intake and feed conversion ratio), nutrient utilization (apparent nitrogen retention and nitrogen corrected apparent Metabolizable Energy (MEn)), carcass characteristics and cost of feed of broiler chickens. Six isocaloric and isonitrogenous diets were formulated using 0, 20, 40, 60, 80 and 100% of BWP. The levels of corn in the basal (0% BWP) starter and finisher diets were 53.7 and 62.78%, respectively. The replacement of dietary corn for up to 100% with BWP reduced costs of total feed and feed for the production of a kg live weight with no impairment on performance, nutrient utilization and carcass characteristics of broiler chickens. It is concluded that BWP can completely replace corn in broiler diets from day to 35 days of age. The substitution of corn with BWP offers economic benefits for both bakery and poultry producers.

  The effects of Delaying access to Feed and water (DF) after hatch and glucose supplementation of drinking water on the performance of broiler chickens were investigated in 2 trials. DF for up to 48 h immediately after hatch depressed performance, weight of bursa of fabricius and heart and small intestine length and thickness. However, the DF period did not influence mortality percentage, feed efficiency, composition of eviscerated carcass and body weight percentage of small intestine, heart and lymphoid organs of chickens at 33 days of age when compared with birds fed immediately after hatch. Access to feed and water after hatch increased body weight gain, feed intake and eviscerated carcass weight over the 33 days experimental period. The addition of glucose for up to 10% to drinking water of DF birds in the 1st 72 h did not influence the performance and eviscerated carcass of DF birds.

  An experiment was carried out to evaluate the effects of replacing corn with extruded Bakery Waste (BWP) in the diet of laying hens on the performance (feed intake, egg production, egg weight, egg mass and feed efficiency) and egg components (albumen, yolk and eggshell) and characteristics of eggshell (thickness and strength) and albumen (height and Haugh unit) and yolk (height and color (YH and YC)) and feed costs of egg production. Six isocaloric and isonitrogenous diets were formulated using 0, 20, 40, 60, 80 and 100% of BWP. The level of corn in the basal diet (0% BWP) was 60.16%. The replacement of corn for up to 100% with BWP reduced feed costs with no impairment on the performance, egg components, characteristics of eggshell and albumen and YH. Replacing dietary ≥40% of corn with BWP reduced YC. It is concluded that BWP can completely replace corn in laying hen diets without affecting the performance, egg components, egg characteristics of albumen and eggshell and YH. Yolk pigment should be added to the diet to improve YC when ≥40% of corn replaced with BWP.

  The effects of high Calcium (Ca, 10 and 25 g kg-1) and Dietary Electrolyte Balance (DEB, 250 (basal diet), 200 and 300 mEq kg-1 (3 diets with high Na, K, Na plus K, respectively) on the performance (Weight Gain (WG), Feed Intake (FI) and Feed Conversion Ratio (FCR)) during the starter and finisher periods (1-20 and 21-33 days of age, respectively) and plasma total Ca and electrolytes and carcass characteristics at 33 days of age of broiler chickens were investigated. DEB treatments were prepared by the addition of NH4Cl, NaHCO3, KHCO3 and NaHCO3 plus KHCO3 to the basal diet, respectively. High Ca diet reduced WG, FI, plasma potassium, eviscerated carcass weight and increased FCR and plasma Ca. Altering DEB of 250 by ±50 mEq kg-1 influenced WG and FI of chickens without altering FCR, plasma total Ca and electrolytes and carcass composition. DEB 200 mEq kg-1 did not influence the performance of chickens. DEB 300 mEq kg-1 had a lower WG than DEB 200 or 250 mEq kg-1 during the starter period. DEB 300 mEq kg-1 with high Na had a higher WG than DEB 200 mEq kg-1 at the finisher period. DEB 300 mEq kg-1 with high K had lower WG and FI of chickens than other DEB treatments and eviscerated carcass weight than DEB 250 mEq kg-1 at 33 days of age. It was concluded that altering DEB within the range of 200-300 did not overcome the growth depression effect of high Ca. DEB manipulation influenced the performance of chickens.

  The effects of in ovo feeding of L-Glutamine (GLN) at 17th day of incubation on hatchability traits, hatching time and chick weight at hatch (CWT and CWT%, expressed as an absolute value and as a percentage of egg weight, respectively) of Ross meat-type breeder eggs were studied at 26 and 32 weeks of age in trials 1 and 2, respectively. The treatments were a non-injected control, a positive control where saline was injected or saline with GLN at 5, 7.5 and 10 mg/egg. In ovo feeding of GLN did not influence hatchability traits, CWT, CWT% and hatching time. In ovo feeding of 10 mg GLN/egg increased percentage of hatched chicks at 468 h of incubation and reduced percentage of hatched chicks at 492 h of incubation when compared with those of the control treatments. Age of birds did not influence hatchability traits and percentages of hatched chicks at 468 and 492 h of incubation and CWT%. Eggs produced at 26 weeks of age had lower weight, percentage of hatched chicks at 504 h of incubation, hatching time and CWT when compared with those produced at older age. It is concluded that in ovo of up to 10 mg GLN/egg at 17th day of incubation of layer-type breeder eggs did not influence hatchability traits, chick weight at hatch and hatching time and eggs produced at older age had higher egg weight, chick weight at hatch and hatched later than those produced at younger age.
