two trials were carried out to compare the effect of different levels of vitamin premix, in two raising systems of floor and cage, on performance and meat quality of broiler chicks. the chicks were fed with adjusted diets as based on wheat and barley for duration of 29 to 42 days. trial 1 was carried out through an employment of 288 male broiler chicks (ross 308) in 4 treatments and 4 replicate...

Between October 15, 2021, and November 26, this study was carried out in the broiler field at College of Agricultural Engineering Sciences, University Baghdad Abu Ghraib to examine effects adding various dosages onion powder, "Allium cepa linn", chicks' diets on physiological characteristics. The experiment employed 225 unsexed (Ross 308) one-day-old chicks with an average weight 40g. A total w...

Two experiments were conducted to determine: first, the best time of excreta collection after force feeding of broilers to yield the maximal amount of excreta, and second, nitrogen-corrected true metabolizable energy contents of some poultry feedstuffs including yellow corn, soybean meal, corn gluten meal, canola meal and poultry by-product meal by a new precision-fed chick assay using 3-week-o...

effect of natural zeolites and nano-zeolite on gut flora, tibia bone characteristics, blood parameters and performance of broilers investigated with 336 male ross 308 broilers chicks allocated to   seven treatments with four replicates and 12 chicks per each. experimental treatments were control (no zeolite supplemented), natural zeolite (0.5, 1 and 1.5 percent) and nano-zeolite (0.5, 1 and 1.5...

the aim of this study was to evaluate the effects of three lighting programs on immune system and performance of broiler chickens. a total of 288 seven day-old male broiler chicks (ross-308) were randomly distributed between three treatments. each group was housed in the separated room with eight pen and 12-birds per pen. the management conditions were similar for all treatments throughout the ...

The purpose of this research to study histological and histochemical characteristics the jejunum in broiler Ross – 308 chicks. A total 120 commercial eggs (Ross-308) were used conduct research, with embryos chicks ranging age from (11,15,21) pre hatch (7,14,21) post ,The samples stained using Hematoxylin-Eosin, Periodic Acids Schiff (PAS), Alcian Blue (AB pH-2.5), Masson’s Trichrom , measure le...

This study was conducted to determine the effects of three different fat sources and their combination on growth performance, carcass traits and intestinal measurements of broiler chickens reared to 42 d of age. Two hundred day-old male broiler chicks (Ross 308) were randomly assigned to one of five treatments with four replicates of 10 chicks based on a completely randomized design. The dietar...

This research was conducted to find out the effect of peppermint and basil as natural feed additives on broiler performance. The objective of the present study was to investigate the impact of the peppermint (Mentha pipreitae) and basil (Ocimum basilicum) as a feed additive on live body weight (LBW), body weight gain (BWG), feed intake (FI), feed conversion ratio (FCR), carcass weight, abdomina...

Securigera securidaca (Fabaceae) or goat pea is growing wild in West Asia, Europe and Africa as an annual herb. In Persian, it is called “Gandeh Talkheh”. The seeds of goat pea are applied in the traditional medicine to treat different dysfunctions e.g., hyperlipidemia and hypertension. This study was done at altitude of 2100 m above sea level. The effects of dietary Securigera securidaca seed ...

An experiment was conducted to determine the digestible amino acids requirements of broilers based on different ideal amino acid ratios for male and female broiler chicks during finisher period. Experimental period began at day 29 and lasted in 42 d of age. A total of 720 male and female broiler chicks were equally distributed to 12 dietary treatments with 15 birds per pen and 4 pens per treatm...
