    A method of making leather from mithun hides comprising: soaking the mithun hides in µ Pre Tan dispersing agent, treating the soaked hides with µ Tan 1, µ Tan II and µ Tan III pastes respectively, subjecting the leathers to the step of drying and brushing, and analysing the amount of moisture and chrome in the leather.

  8. A method of processing rabbit fur on leather

  9. Feed blocks: preparation of low-cost nutritious feed blocks for mithun

    Complete feed block developed for better growth and production reduced dustiness, improved palatability as well as digestibility of nutrients, thereby increased the productivity in mithun for higher income. The feed blocks were made from locally available feed ingredients. Three leaves, straw and concentrate feed were mixed together and pressed by using feed block making machine. Similarly, feed blocks were also made from paddy straw and spent gains (a breweries industry by-product) with high moisture content (75-80%). Simultaneously, methods have also been developed for drying high moisture content by products (spent grain/fodders more efficiently during rainy season). Performance of mithun was found to be good with average daily growth (ADG) of 500 g in tree leaves based feed blocks and 553.6 g from spent grain based feed blocks as against ADG of 396.2 g in control feeding.

  10. Mineral Mixture: Feeding of Area specific mineral mixture

    The content of minerals varies from region to region due to several reasons. In mithun inhabited areas, mineral content of many tree leaves are in higher side, which used to cause an improper proportions of minerals in their diet. Further, the minerals are liable to form bonds and interact more than one nutrient. This reduces their bioavailability. Therefore, there is substantial micronutrient deficiency in mithuns as evidenced from analysis of blood plasma mithun.

  11. Standardization of semen preservation and artificial insemination in mithun

    Improvement of the production performance of mithun, it is required to breed females with the semen of the bulls of superior genetic merits. This can be achieved easily through the artificial insemination (AI) with preserved semen. Considering the importance of it, different methods have been standardized for semen preservation and AI in mithun. Mithun semen could be preserved successfully at 4°C (liquid semen) and keeping quality of the preserved semen was found to be good for approximately 2 days. Mithun semen could be successfully cryopreserved in liquid nitrogen (-196°C) using tris-egg yolk-glycerol or citrate–egg yolk–glycerol diluent. It was observed that 5% glycerol concentration in the diluent was suitable for preserving semen in liquid semen. Moreover, the sperm quality was found much better (approximately 23-25% increase in progressive motility and count of live sperm with intact acrosome) when 5% glycerol was added in split doses compared to single dose. It was also observed that for cryopreserving mithun semen, tris-egg yolk-glycerol diluent is better than citrate-egg yolk- glycerol diluent. The scientist could successfully produced mithun calves through AI using liquid and cryopreserved mithun semen both at farm and field levels.

  12. Estrus synchronization

    Estrus synchronization is the manipulation of reproductive process so that female can be bred with normal fertility during a short and predefined interval. It facilitates breeding in two important ways: it reduces and in some cases eliminates labour of detecting estrus and it allows the producers to schedule the breeding. Considering the importance of synchronization of estrus in mithun, estrus synchronization protocols for timed AI in mithun has been developed using PGF2α, GnRH-PGF2α-GnRH (Ovsynch) and controlled intravaginal drug (progesterone) releasing device (CIDR).
    After developing these protocols in mithun, in the next step we went for fixed time artificial insemination following synchronization. Initially, a total of 16 animals were inseminated artificially (AI) with the cryopreserved mithun semen, 12 cows were conceived. These protocols are routinely practised in the institute farm. 

  13. Standardization of embryo transfer protocol in mithun

    Donor and recipient mithun cows were synchronised into estrus by using CIDR. Donor’s cows superovulated at day 10-13 post estrus by using FSH (Folltropin-V-Bovine- 400 mg for 4 consecutive days at two divided doses daily). PGF2α (5 ml) was administered on day 3 of FSH treatment. Flushing was carried out on day 6 of the estrus cycle (considering day 0 = day of estrus) by non-surgical method using 2-way Folly’s catheter followed by searching and evaluation of embryo under stereo zoom microscope. Embryos have been recovered from the donor’s animals and were transferred into three recipient animals. Pregnancy was monitored through ultrasonagraphy. The first calf named as BHARAT was born in March 27, 2012 and the second calf (PRITHVI), which was born on May 11, 2012. The standardisation of embryo transfer protocol in mithun would definitely help in conservation and propagation of quality germplasm in all the mithun inhabited areas of NEH region.

  14. Standardization of cryopreservation protocol for mithun embryos

    After recovery from the donors animal, the embryo was evaluated and washed in DPBS medium followed by embryo equilibration in solution -1 for 5 min (10% glycerol + 0.125M sucrose + 0.125M Dextrose +10%FCS in PBS) and in solution -2 for  5 min (10% glycerol +10% ethylene glycol + 0.25M sucrose +0.25M Dextrose + 10% FCS in PBS). After that embryo was placed in pre-cooled (4°C) virtification solution (20% glycerol + 20% EG + 0.375M sucrose +0.375M dextrose +10% FCS in PBS). Immediately aspiration of embryos (within 60 sec) in a 0.5 ml French straw loaded with 0.5M sucrose and sealed with PVA powder. The straw was kept on liquid nitrogen vapour for 1 min then plunged into LN2 (-196°C). On the 100th day, the embryo was transferred into a recipient animal and MOHAN, the first mithun calf was born on May, 12, 2012 through embryo transfer technology (ETT) from a cryopreserved embryos.

  15. Aging of mithun by dentition

    A dentition pattern of mithun for determination of age under field condition have been established and was found to be different than cattle where the temporary incisors appeared within birth to 3 months of age in mithun compared to within two weeks of age in cattle. Similarly, the eruption of permanent incisors in mithun differed than that of cattle as given in the table.

  16. Creating of awareness among the mithun rearers/owners through Extension/TSP programmes

    Awareness was created among the mithun farmers/ rearers/owners about the different aspect of mithun management. In health aspect, creation of awareness about the various diseases that affect the mithun, various zoonotic diseases, inter and intra spread of infections, awareness about the importance of vaccination, deworming  and its schedule, handling of infected and dead animals, first aid treatment for animals infected at the time of outbreak, regular lectures or training on health management of mithun. In animal reproduction and physiology, awareness about the importance of heat detection, semen collection, preservation, artificial insemination, various reproductive health problems & diseases, multiple ovulation embryo transfer technology and estrus synchronization. Moreover, regularly conduction of lecture cum practical training, mass reproductive health check-up. The information related to the nutrition related like preparation of low-cost nutritious feed blocks and feeding of area specific mineral mixture for mithun and other related livestock species in the NEH region. In animal genetics and breeding aspect, various types of breeding programme, ways in which to prevent the inbreeding depression, selection of male and female for breeding programme, etc. Preparation of various leather, meat and milk products from mithun was explained and demonstrated.

  17. Semi-intensive mithun farming

    It is traditionally believed that mithun, a unique domesticated animal of the North-Eastern hilly region, can be reared only under free-range forest rearing system. But with the decreasing forest coverage in the region, it is imperative to find an alternative rearing system. The package of practices for alternative semi-intensive mithun rearing system, developed by the Institute, has already been practiced successfully in the Institute’s Mithun Farm. On 30th April 2016, the alternative semi-intensive system of mithun rearing under farmers’ fields at Molvom village of Medziphema block, Dimapur, Nagaland was launched. On this occasion, under Tribal Sub-Plan (TSP), nine mithun cows and one mithun calf were distributed among three farmers of Molvom village.
