A breeding program to improve income from Raeini cashmere herds run by nomads in Southern Iran was implemented. Eight nomads agreed on improving fleece weight, body weight and down yield while reducing cashmere fibre diameter of white coated goats. Economic weights were calculated to define a breeding objective. Each nomad established a breeding nucleus selecting visually his best 40 does and two bucks from about 250 goats. Nomads used different systems to ensure separate mating of nucleus and general herd animals. Nomads were also able to identify the progeny of each buck. Nucleus progenies were recorded for weaning weight and fleece weight. Fleece samples were collected for analyses of down yield and down fibre diameter. General herd male progeny was castrated. Formal selection indices were used to select nucleus male replacements. To construct the indices phenotypic and genetic parameters were taken from project data and published figures. Accuracy of indices ranged 0.47 to 0.66 depending on the traits included. The inferior buck based on progeny index average was replaced by the best young buck available. Other high ranked young bucks were used in the general herd. The breeding program is in its fourth cycle and favourable selection differentials were confirmed for selected bucks in all traits of interests, in particular for down weight and down diameter, 62. g and -0.5. μm, respectively. The expected benefit of the program is about 4.0 USD accumulating per goat and per year. Fleece testing is an issue since the region lacks a fleece testing service. If fleece sampling is discontinued the expected benefit reduces to about 2.8 USD per goat and per year. Circular use of bucks to control inbreeding and participation of additional nomad families are planned for the future. This experience shows that a participatory breeding program can be successfully implemented under nomadic conditions through intensive collaboration of nomad herders, regional extension officers and scientists. © 2015 Elsevier B.V.

Shrimp farming is an important industry but several infectious diseases have caused high economic losses all over the world. Until now, many pathogens that include viral, bacterial and fungal species have been identified which are affecting sustainable development of this industry. Therefore, research in terms of immunity is of primary concern to control disease and to ensure long-term survival of the shrimp culture industry. There is increasing evidence indicating that nutritional genomics represents a promise to improve marine health. This goal will be reached by highlighting the mechanisms through which diet can reduce the risk of monogenic and common polygenic diseases. Indeed, nutrition is a very relevant environmental factor involved in the development and progression of metabolic disorders as well as other kind of diseases. To date, it is widely accepted that most of the effects of the nutrition on shrimp diseases and in turn, on marine health cannot be easily explained without a complete knowledge of the molecular mechanism underlying the nutrients action. In particular, the evidence shows that understanding how nutrition affects the metabolic homeostasis, influencing different cellular metabolic pathways is a crucial event. The aim of this mini review is describe of pervious nutritional genomes researches of shrimp health and improvement of immune system response. © Medwell Journals, 2010.

Variations at DNA level contribute to the genetic characterization of livestock populations and this may help to identify possible hybridization events as well as past evolutionary trends. The leptin and Pit-1 are attractive candidate genes for production and reproduction traits in cattle. A total of 247 animals from four breeds from two species of Iranian cattle populations in include Bos taurus (Sarabi, Golpayegani) and Bos indicus (Sistani, Taleshi) were genotyped for the Pit-1 Hinfl and leptin Sau3AI polymorphisms by the Polymerase Chain Reaction and Restriction Fragment Length Polymorphism (PCR-RFLP). The genotype and gene frequencies for each group were determined and shown to be quite variable among the breeds. The allele B for the leptin gene and allele A for the Pit-1 gene were investigated high frequency in Bos indicus. Candidate gene approach may be a useful method to measure of genetic distance for cross breeding program between taurin and indicine cattle. © Medwell Journals, 2010.

The income of the nomads in Kerman Province depends mainly on Raeini goats that produce meat, milk and cashmere. This paper assesses the cashmere quality and its variation in Raeini herds to determine the scope for improvement. In April 2010 fleece weights (FW) and midside fleece samples were taken from a total of 686 male and female cashmere goats of 1, 2 and 3 years of age belonging to 29 herds. The herds were randomly chosen in the summer grazing area of nomads within 20. km of the city of Baft, province of Kerman, South of Iran, the main cashmere producing area in Iran. Cashmere yield (CY) was determined from the weight of dehaired cashmere to weight of shorn fiber. Cashmere fibers were analyzed using an OFDA instrument. A general mixed linear model including sex, age and sex by age interaction as fixed effects and herd as random effect was used to analyze the data and measure the relationships between different cashmere characteristics and fleece attributes. The overall means. ±. standard deviations were for fleece weights (FW) 507. ±. 183. g, cashmere yield (CY) 56.5. ±. 12.2%, mean fiber diameter (MFD) 19.7. ±. 1.5. μm, fiber diameter standard deviation (FDSD) 4.5. ±. 0.6. μm, fiber curvature (FC) 62.9. ±. 8.5°/mm and staple length (SL) 54.2. ±. 7.0. mm, respectively. Herd effect was significant for all traits except for SL and sex by age effect was only significant for MFD. One year old males and females had finer cashmere than older goats. FW and FDSD were higher in males and CY and FC was higher in young animals. Pearson correlation between MFD and FC, FDSD and MFD, MFD and FW was -0.647, 0.399 and 0.211 respectively. Raeini cashmere is white, has an excellent SL and FC but is relatively coarse. Given the differences between and within herds there seems to be substantial scope to improve the commercial value of Raeini cashmere. © 2011 Elsevier B.V.

This study was conducted to evaluate the effect of a dietary mixed medicinal herbs powders (MHPs) (Thymus vulgaris, Pennyroyal, Cumin, Alhagi, Garlic and Eucalyptus globules) on performance, egg quality and immunity response of laying hens. The experiment was carried out under completely randomized design, including five treatments (Treatment 1= basal diet without additive (control group), Treatment 2= basal diet + probiotics at 0.1%, T3, T4 and T5=basal diet +1, 2 and 3% MHPs respectively) with five replicates (12 birds each replicate). 300 Bovans laying birds (49 wks old) were distributed randomly in cages and allotted into one of experimental diets for 84 days. The performance was recorded every week. In order to examine the antibody against the sheep red blood cell (SRBC), 2 piece of hen from each replicate was randomly chosen (1cc) SRBC (%0.5) was injected and ten days later blood samples were collected. To examine the blood parameters (Serum Cholesterol, Red blood cells, White blood cells, Lymphocyte, Packed cell volume), In the day 70th, from each replicate 2 piece of hen blood samples was taken. Egg quality parameters (High unit, specific gravity, shell weight and thickness and yolk cholesterol) at the end of the experiment were evaluated. Diets supplemented with 1, 2, or 3% MHPs had no significant effects on percentage of egg production, egg weight mass, and feed conversion ratio (FCR). However, at the level of 2 and 3%, daily feed intake decrease significantly (P< 0.05) compared to the control, probiotic and 1% MHPs. Probiotic and different levels of MHPs had no significant effect on SRBC. Probiotic and 1 and 2% MHPs significantly (P < 0.05) decrease IgG in compare to control and 3% MHPs. Using probiotic in the diet significantly increase IgM in laying hens in compare to control and different levels of MHPs. Probiotic and levels of MHPs had no significant effect on egg weight, shell weight, shell thickness, specific gravity and haugh unit and serum cholesterol. However, MHPs at the level of 1% increase yolk cholesterol in compare to probitic, control, 2 and 3% MHPs significantly. In conclusion, using medical herbs in mixed form may suppress positive effect of medical herbs in compare to using individually. © 2013 AENSI Publisher All rights reserved.

Pastoralism | Year: 2016

The nomadic pastoralist system in Baft district in Kerman province is well known in Iran for producing cashmere from Raeini goats. However, there is little information regarding the organic sheep and goat production systems. Interviews and field observations were carried out with 30 Siahjel nomad families of Raen origin in proximity of Baft city to characterize the organic production system in terms of feeding, animal health and veterinary treatments, husbandry management practices, transport, slaughtering and housing. Unimproved rangeland was found to be the main source of sheep and goat nutrition belonging to nomads in southern Iran. Nomad livestock were not fed in stables or in restricted areas but moved and grazed freely in extensive open grazing areas. As a nomadic traditional feeding management practice, there were no minerals, vitamins, pro-vitamins or GMOs for animal feed. Nomad sheep and goat breeds were considered to be robust, adapted to the environment and disease-tolerant livestock. In the nomadic system, no animal cruelty practices such as tail ducking, dehorning and tethering were allowed. To keep ruminants in groups to meet their social needs, nomad families stayed and kept animals together to support each other in different livestock activities, including shepherding, feeding, milking and health care. Due to natural breeding in nomadic herds, the male breeding stock was kept and grazed separately from does during the breeding season. Nomadic livestock products, i.e. meat, milk, wool, could be labelled organic after making local studies, surveillance, regulation and certification. © 2016, Ansari-Renani.

The objective of this present study was to investigate relationships between the growth hormone gene restriction fragment length polymorphism (RFLP) and bull sperm characteristics. A total of 89 bulls from two semen evaluation stations were genotyped for the bovine growth hormone (bGH)-AluI polymorphism by polymerase chain reaction and followed by 4% metaphor agaros gel electrophoresis. The overall allele frequencies for two L and V alleles were 0.50, respectively. The relationship between the bGH-AluI polymorphism and semen characteristics was evaluated according 1500 ejaculated records. Five sperm characteristics were analyzed. Sperm characteristics showed significant variability in relation to bGH genotypes. LL bulls had a lower ejaculated volume and higher percentage of live sperm, and VV bulls had higher fresh sperm concentration and minimum effect after cryopreservation. This polymorphism could be further used for semen evaluation process in artificial insemination program in Iranian Holstein bulls. © 2011 Academic Journals.

Pastoralism | Year: 2013

The nomadic pastoralist system in Baft district in Kerman province is well known in Iran for producing cashmere from Raeini goats. However, there is little information on the production system. Interviews were carried out with 30 Siahjel nomad families of Raen origin in proximity of about 20 km to Baft city in 2010 to characterise the production system in terms of family labour force, work sharing, livestock numbers, management and marketing practices, and diseases. The nomads move their livestock over large distances within the rangelands of the region from May to November, and the majority migrate south during autumn and winter. Of the nomad families, 87% live with and manage their animals together with one or more other related families. All household heads are males. All family members are involved in raising livestock; males and hired labourers dominate the physically harder jobs like shepherding and breeding, while women are involved in milking and caring. Of the animals, 80% are owned by adult or young unmarried males, none by daughters. Average proportion of goats and sheep per family flock are 89% and 8%, respectively, which indicates that Siahjel nomads mainly rely on goats. Adult breeding females constituted the largest group within the goat herds. The rationale for keeping a high number of male goats may be related to their greater production of cashmere. Diseases accounted for 57% of adult and 88% of young animal deaths. The most prevalent diseases were enterotoxaemia, foot-and-mouth disease, pneumonia, agalactia and diarrhoea. Animal sales, meat, cashmere and milk production are the major reasons for keeping goats. Rangeland is considered as the main source of feeding (85% of total annual feed intake); the remaining 15% is provided by stubble grazing. However, the herds do not produce enough meat, milk and cashmere to sustain the life of the nomad families, and thus, they often have to sell part of their stock which will further decrease their income. © 2013, Ansari-Renani et al.; licensee Springer.

The effect of using small or large cashmere combs on cashmere harvest, cashmere quality and combing time was studied on Raeini cashmere goats in nomadic goat breeding systems of the Iranian province of Kerman. Two groups of 20 goats of different ages were combed with either a large or a small comb, three times with intervals of 2 weeks in early spring when natural fiber shedding has started. Combed cashmere weight, duration of combing, fiber diameter, and down yield were measured. A sample of combed cashmere was analyzed using a Laserscan instrument. A general linear model including type of comb, stage of combing and age of goat was fitted to analyze the data. Small combs collect more cashmere (31.0 vs. 21.7. g, P< 0.01) than large combs without affecting down yield or down fiber diameter (P> 0.05) but combing time is higher (3.75 vs. 2.79 min, P< 0.01). In the first two combing sessions much more cashmere was obtained than in the last (28.1, 32.0 and 19.0. g, respectively, P< 0.01), but the weight of total combed cashmere was much less than typical shorn fleece weights. Combing can be justified only if a considerable price premium can be obtained from selling combed cashmere instead of selling shorn cashmere, or if the combed cashmere is used to add value on-farm. If this is the case, small combs with short rods are preferable since more cashmere can be collected without affecting its quality. © 2013 Elsevier B.V.
