Purpose: This study was carried out for detection of possible polymorphisms in Booroola gene (FecB) and growth differentiation factor 9 [GDF9] in Lori sheep breed. Methods: Blood samples were taken from the jugular vein of the sheep and their DNA content extracted using modified salting-out method. The quantity and quality of extracted DNA was exam...

This experiment was designed to study the effects of feeding different levels of Peganum harmala seeds (PHS) and antibiotic on the performance, immune responses and liver function of Ross broiler chickens. A total of 240 one-d-old unsexed broiler chickens were randomly allocated to each of the 4 treatment groups, each with 4 replicate pens of 15 ch...

The aim of this study was to verify polymorphism of the BMP-15 and GDF9 genes in Lori sheep breed. These loci are located in the region of ovine chromosome X and 5, respectively. In this study, blood samples were randomly collected from 123 ewe Lori sheep breed in Lorestan province and subsequently their DNA content were extracted using modified sa...

Calpastatin and callipyge have been known as two of the candidate genes in meat quality and quantity. Calpastatin gene and callipyge gene has been located to chromosome 5 and 18 of sheep. The objective of present study was to identification of calpastatin and callipyge genes polymorphism and survey of genotype structure in population of Lori sheep...

This experiment was conducted to evaluate the effect of onion extract and antibiotic on growth yeild, and carcass characteristics, in broiler chicks. A total of one hundred and ninety two1-day old mixed sex broiler chicks (Ross 308) were randomly assigned to four experimental groups. Each treatment was included of 4 replicate. Experimental groups i...

Objective: To examine the effect of onion (Allium cepa L.) as an antibiotic growth promoter substitute on growth performance, carcass traits, and microflora composition in broiler chickens. Methods: A total of 192 one-day old mixed sex broiler chicks (Ross 308) were weighed and randomly allocated to four treatment groups, each with 4 replicate pens...

The callipyge locus has been localized in the telomeric region on ovine chromosome 18, within a cluster of imprinted genes. In this study were collected blood samples from 124 Lori sheep. Genomic DNA was extracted from blood sample. Gel monitoring and spectrophotometer methods were used to determination quality and quantity of DNA. FaqI enzyme was...

This experiment was conducted to evaluate the effects of different levels of powdered Mentha pulegiumL. (pennyroyal; medicinal plant) obtained from its dried aerial part on performance and carcass traits, of broilers. 200 broiler chicks (Ross 308) were used in a completely randomized design in five treatments and four replicates (10 birds per repli...

Objective This trial was conducted to examine the effect of usage different levels of ethanolic extract of peppermint (Mentha piperita) in drinking water in comparison with an antibiotic growth promoter (Virginiamycin) on the growth performance, and carcass traits of broiler chicks.Methods Birds were assigned to 5 treatments: control feed, antibiot...

The study was conducted to evaluate the effects of Mentha spicata extract and an antibiotic -virginiamycin- on immune system, blood factors in broiler chickens. A total of four hundred 1-day old chicks (Ross 308) were allocated to five treatments with four replicates based on a completely randomized design. The dietary treatments consisted of the b...

In order to study the effects of two kinds of clinoptilolites (Calcic and Potassic) on ruminal parameters, four fistulated mature male sheep were used in a change over design as balanced latin square. The formulated diets(contain 60% concentrate and 40% forage) include: 1) control, 2)4% Calcic clinoptilolite, 3) control + 4% Potassic clinoptilolite...
