A study was conducted to compare the growth performance as well as blood and carcass variables of two broiler strains reared in a conventional broiler house and a modified greenhouse equipped with cooling pads and tunnel ventilation system. Eight hundred day-old chickens of two commercial strains (Ross 308 and Lohmann) were selected and placed in 8 floor pens (4 pens of 50 broilers for each strain in each housing system). The pens were located randomly throughout the modified greenhouse or the conventional broiler house (two-way ANOVA design). The broilers were provided a standard starter and grower diets ad libitum. The environmental conditions (i.e. temperature, relative humidity, lighting program and ventilation rate) were kept similar between the two houses. The results showed that the birds in the greenhouse consumed significantly (p <0.05) more feed during the starter period (1-21d) and throughout the trial (1-42d) in comparison with those reared in the conventional house. Strain difference and strain × house interaction had no significant effect on the measured parameters i.e. body weight gain, feed conversion ratio, hematocrit, heterophil:lymphocyte ratio, serum nitric oxide concentration, carcass and breast yields. However, birds reared in the green house deposited more fat in their abdominal cavity compared to their counterparts in the conventional house (p <0.05). Interestingly, from the economic point of view, the construction cost of a greenhouse was estimated approximately one-third of a conventional house (≈40.00 vs 120.00 US$ per square meter). In conclusion, modified greenhouses equipped with cooling pads and tunnel ventilation system are recommended for low-cost rearing of broiler chickens.

The aim of this study was to examine whether the secreted fluid from the uterus influences the survival and fertilization capacity of fowl sperm in the hen oviduct. Hens with either regular uterine fluid secretion or irregular uterine fluid secretion were artificially inseminated through the transfer of sperm into the uterus. Twenty-four hours after artificial insemination, 3 hens with regular uterine fluid secretion and 3 hens with irregular uterine fluid secretion were killed and the utero-vaginal junction and infundibular sperm storage tubules were observed for the presence of sperm. There was no difference (P>0.05) in the fill rate of either the utero-vaginal junction sperm storage tubules or the infundibular sperm storage tubules between hens with regular or irregular uterine fluid secretion. However, the sperm transferred into hens with regular uterine fluid secretion had a longer lifespan and fertilization ability than the counterpart group (Psecretion from the hen uterus may sustain the longevity and fertilization ability of fowl sperm in the oviduct.

This research was carried out to investigate the effects of various levels of dietary organic selenium supplementation (0, 0.1, 0.2 and 0.3 mg/Kg) on reproductive traits of rooster. Semen was collected using abdominal massage and samples were mixed together. Sperm characteristics including percentage of motile, viable and abnormal sperms were assessed. This experiment was carried out based on a completely randomized design. Results showed that the organic selenium supplementation had significant effects on perm motility and viability in liquid condition (P0.05). In conclusion, the use of organic selenium supplementation (0.3 mg/Kg) in diet of rooster could be recommended to improve semen quality.

The presence of microbial load and high fiber content in various non conventional feedstuffs limit their utilization in poultry feed. In the present study, the feedstuffs were treated with acidified sodium chlorite (ASC) and its impact on the microbial load and metabolizable energy availability was assessed in the chickens. The effect of supplementation of feed grade enzyme was also evaluated either alone or in combination with ASC treatment. ASC was prepared by adding citric acid to an aqueous solution of sodium chlorite (625 g/liter). The sanitizing effect of ASC was assessed at 0, 100, 250 and 500 ppm levels in the meat cum bone meal (MBM) and sunflower meal (SFM), while its impact on the energy bioavailability from SFM and de-oiled rice bran (DORB) was assessed at 0, 100 and 250 ppm levels with (0.3 g/kg) and without exogenous enzyme supplementation. The results revealed that ASC treatment was effective in reducing the microbial load in MBM and SFM. Regarding the metabolizable energy availability, ASC treatment produced appreciable improvement both in SFM and DORB, while enzyme supplementation was effective only with SFM. It may be concluded that ASC treatment has a sanitizing effect and improves the energy bioavailability from feed ingredients like SFM and DORB in the chicken.

A total number of 5520 female and 480 male breeders (Arbor Acres plus) at 42wks of age were used in a 10-week-trial to investigate the effect of an enzyme complex on the quality and quantity of egg production as well as hatchability of broiler breeders fed a corn-soybean meal diet. There were two dietary treatment groups: a control group fed on a corn-soybean based diet, and the multi-enzyme group that received the same diet plus an enzyme complex including xylanase, amylase, protease, phytase, ß-glucanase, hemicellulase, and pectinase. Results showed that egg production rate and egg mass were numerically increased as a result of enzyme supplementation and differences between the treatment groups were significant at week 46 (P<0.05). Hatchability was not influenced by supplementing multi-enzyme mixture in the diet. The proportion of cracked and broken eggs was signed (P<0.05) improved after using multi-enzyme supplementation in the diet of breeders. In conclusion, egg production and egg mass were increased as a result of multi-enzyme preparation. Significant improvements achieved in egg shell quality led to a greater number of eggs for hatching, though hatchability itself, was not improved by multi-enzyme supplementation.

The Japanese and English White quails are widespread strains and belongs to the Galliformes order, Phasianidae family, Coturnix genus and Japonica species. These birds are likely to be well-adapted to the hard conditions and resistance to diseases as it has attained economic importance as an agricultural species. In the current study, the genetic variation of Japanese and English White quail populations were studied. Frequency of polymorphic loci, polymorphic information content, heterozygosity, Shannon's information index, number of observed and effective alleles were assessed using 4 microsatellite markers with high polymorphic information content value (GUJ0034, GUJ0049, GUJ0080 and GUJ0097). The Blood samples were collected randomly from 50 Japanese quails and 50 English White quails rearing in the research center of Gorgan University of Agricultural Sciences and Natural Resources. The genomic DNA was extracted using DIAtom DNA Prep 100 kit, and its quality and quantity were determined using electrophoresis gel and spectrophotometery methods. The PCR reactions were successfully performed with four microsatellite markers. The results based on the chi-square and likelihood ratio tests showed a significant deviation from Hardy-Weinberg equilibrium. The means of genetic diversity parameters such as number of effective alleles, the number of observed alleles, the expected and observed heterozygosity, Shannon's information index and PIC in quail populations were 4.78±0.37, 7.50±0.57, 0.79±0.02, 0.60±0.16, 1.73±0.05 and 0.76±0.02 respectively. The results of the current study showed that the investigated quail populations have a relatively high genetic diversity with respect to the applied microsatellite markers and confirmed prior study’s findings on the ability of microsatellite markers in investigating genetic diversity.
