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. Source

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.

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. Source

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. Source
