This study was conducted at the poultry farm of Animal production Department at College of Agriculture University of Qadisiyah during the period from 9/4/2015 to 20/5/20015 and in a Laboratory dealing with the analysis of molecular genetic in College of Agriculture University of Baghdad. The objective of this study was to identify the genotypes for Myostatin gene (GDF-8) of Ross broiler, using three type of Restriction enzymes (Aci I, Bbv I ,Bbs I), by technique the Restriction fragment length polymorphisms (RFLPs).
The results of this study can summarized as follows.
The percentage of genotype distribution for the Myostatin gene by Restriction enzyme Aci I in sample of studied was 32, 54 and 14 % for the genotypes. GG, GA and AA respectively and the differences between these percentages was highly significant. The alleles frequencies for alleles (G) was 0.59 while the alleles frequencies for alleles (A) was 0.41 according to the analysis of Myostatin gene (GDF-8) in this study.
The percentage of genotype distribution for the Myostatin gene by Restriction enzyme Bbs I in sample was 6.78, 86 and 31.36 % for the genotypes. CC, CT and TT respectively and the differences between these percentages was highly significant. The alleles frequencies for alleles (C) was 0.38 and (T) was 0.62 respectively according to the analysis of Myostatin gene (GDF- 8) in this study.
The percentage of genotype distribution for the Myostatin gene by Restriction enzyme Bbv I in sample of studied was 98 and 2 % for the genotypes. AA and GA respectively. The allele’s frequencies for alleles (A) was 0.98 and (G) was 0.02 respectively according to the analysis of Myostatin gene (GDF-8) in this study.

Effect of dietary HMB-Ca on some morphological and chemical parameters of broiler chicken blood

iraqi poultry sciences journal, Volume 10, Issue 2, Pages 44-52

The experiment was conducted to investigate the effect of adding three levels of Beta-hydroxy-Beta-methylbutyrate Calcium (HMB-Ca) to broiler diet on blood cellular and biochemical parameters. A total of 216, day old Ross-308, unsexed broiler chicks were randomly distributed into 4 treatments with 3 replicates for each (18 chick/replicate). Birds were dietary treated with HMB-Ca from day old until the end of experiment (35 day) as follows: T1control group without any addition, T2: basal diet with 0.1% HMB-Ca, T3: basal diet with 0.15% HMB-Ca and T4: basal diet with 0.2% HMB-Ca. Results showed that adding 0.2%% HMB-Ca to broiler diet resulted in significant (P<0.05) increasing in: MCHC,PCV,Hb and blood sugar whereas total count of red blood cells and its volume and the level of serum total protein didn’t affected significantly.

Effect of Adding Different Levels of Lycopene to the Diet In physiologic Performance of Female Quail

This study was conducted in the Poultry Research Station – department of Animal Resources Research – office of Agricultural Research – Ministry of Agricultural Abu Ghraib, during the period from 9/8/2015 to 10/10/2015. The aim of this study was investigate the effect of adding different level of lycopene to the diet on physiologic performance of female quail. Four hundred eighty quail birds were used in this study at age 12 week, Quail birds distributed randomly to 4 treatments with 3 replicates (40 quail birds per replicate). Quail birds were fed one diet during the experiment. The diet contains 20 % crude protein and 2903 Kcal metabolic energy / kg. Lycopene was added to the birds diet from the beginning untill the end of Experimental treatments were as follow T1 (Control diet) without supplement T2, T3 and T4 Supplementing 100, 200, 300 (mg lycopene /kg diet) respectively. Results revealed that dietary supplementation with different levels of lycopene resulted in .Adding different levels of lycopene to the diet recorded significant enhancement (P≤0.05) in the biochemical traits of female quail serum, especially for T4 which recorded an increasing in protein level and high density lipoprotein (HDL), while the glucose levels still within normal range. The results also recorded significant reduction (P≤0.05) for cholesterol, triglycerides (TG), low-density lipoprotein (LDL), very low-density lipoprotein (VLDL) and malondialdehyde (MDA) for lycopene treatments. We conclude from this study the possibility of adding lycopene to feed level of 200 mg/ kg feed to get a positive improvement in the biochemical characteristics of serum.

This study was conducted at the Poultry Farm, Department of Animal Resource, College of Agriculture, University of Baghdad during the period from September 19th, 2014 to October 31st, 2014 to investigate the effect of different levels of dietary Marjoram (Origanum majorana) powder supplementation on productive and immunological performance, carcass qualitative properties, oxidation markers as well as the microbial contents of the digestive system. Four hundred and fifty- one old day chicks of Ros 308 were randomely divided into five treatments (90 chicks per treatment) with three replicates (30 chicks per replicate). Chics were fed on starter and final rations with 23 and 20 % crude protein and 3027 and 3195.3 Kcal / kg diet respectively, in addition to the five levels of Marjoram powder (0, 0.5, 1, 1.5 and 2 kg per ton diet) as T1, T2, T3, T4 and T5 respectively. The supplementation groups (T2, T3, T4 and T5) exhibited higher (P≤ 0.05)body weight, weight gain, productive index and economic marker, whereas, lower (P≤ 0.05) feed intake were noticed for them as compared with T1 group.
Conclude from this study that the addition of marjoram powder to diet chicken meat led to an improvement in the qualities of live body weight and increase the weight weekly and total and the rate of feed conversion with a decrease in the amount of feed intake and high the values of all of the productive index and economic marker broiler chickens jam 42 days.
