ABSTRACT: This research is an attempt to explore a step ahead with the previous research. It will also redefine the definition of sustainability which is based on the viability of a unit over the time horizon. The objective of this paper is to determine the economic viability associated issues and impact of marketing strategy namely one (Complete control over the chain of production to marketing), two (Joint arrangement in marketing) and three (Wholesaler and retailer system of marketing) on economic viability of dairy farming. The data has been raised on the basis of a schedule prepared for the purpose from a cross section of the region using snow- ball technique. Analysis of data is based on an Econometric model. The finding of this research paper is that milk producing units in the region are economically viable. But this economic viability is influenced by marketing strategy Therefore, it concluded that the milk producing units opting marketing type one ((Complete control over the chain of production to marketing),) & the milk producing units opting marketing type two ((Joint arrangement in marketing)) in the region are Economically unviable but if the milk producing units opting marketing type three ((Wholesaler and retailer system of marketing),) in the region are Economically viable.

Key words: Dairy farming Economic Viability, Marketing strategy, Sustainability.

ABSTRACT: Evaluation of semen quality is very important before selection of breeding cocks used for artificial insemination. The aim of this study was to characterize the semen parameters of 4 lines of cocks followed by comparison of such parameters among lines. A total of 60 semen samples were collected from 3 Sasso, 3 Synthetic and 3 White Rock and 3 Assel RIR cock at 3 days interval. Semen was collected by abdominal massage method. Semen parameters with respect to ejaculate volume, mass activity, sperm motility, sperm concentration, proportion of live spermatozoa and proportion of spermatozoa with normal morphology were examined. The semen parameters did not differ significantly among individual cocks of Sasso line. However, sperm concentration varied significantly among individual cocks of Synthetic, White Rock and Assel RIR lines. The ejaculate volume, mass activity, sperm motility, sperm concentration, proportion of live spermatozoa and proportion of spermatozoa with normal morphology varied from 410.0 ± 0.0 to 810.0 ± 0.0 μl, 3.8 ± 0.1 to 4.0 ± 0.0 +, 71.1 ± 1.1 to 83.3 ± 1.2%, 7.5 ± 0.1 to 9.6 ± 0.2 x 109/ml, 82.2 ± 1.3 to 87.3 ± 1.1% and 87.2 ± 0.8 to 90.1 ± 0.7%, respectively. However, only the variations in ejaculate volume, sperm motility, sperm concentration and proportion of live spermatozoa were significant among lines of cocks (P<0.05). It is concluded that semen quality of different lines of cocks were within normal range although variations in some parameters of semen may exist among lines.

ABSTRACT: The study was conducted to evaluate the efficiency of platelet rich plasma (PRP) gel in the healing of skin wound.This experiment was carried out to exploit the therapeutic effects of PRP gel on healing process. A total of 72 surgical wounds were madein 12 goatsbearing weight 15-20 kg with the age 1-3 years. Goats were divided into four groups with three animals in each group. Wounds of four groups were treated with homogenous PRP gel, heterogenousPRP gel, sulphonilamide powder and tincture benzoinCo. or benzoin seal (control). The wounds were 3 cm length and 0.5 cm depth sutured with cross mattress using nylon. Follow-up observation was recorded from day 1 to day 30 postoperatively. Some morphological characters such as swelling area of wound, elevation of sutured line from the skin surface, width of sutured area and contraction length between 7 to 15 days were recorded to determine the healing process of the wounds. Besides morphological study, histopathological studies were also performed on day 1, day 2, day 3, day 5 and day 15 to evaluate the healing process.HomogenousPRP gel showed admirable results in the healing of the wounds produced in goat. All wounds treated with homogenous PRP gel showed no inflammation with dry sutured area and complete healing with massive hair follicular growth within 15-21 days. On histopathological study, demonstrated epithelial tissues with a normal morphology. The dermis showed flabby connective tissue with organized interconnecting collagen fibers running parallel to each other and new hair follicular growth inhealed area within 15 days, when wounds were treated with homogenousPRPgel.This study could help to consider natural biomaterial product specially PRP gel homogenous for a good healing of skin wounds with minimum complications. Further studies are necessary for the molecular investigation of healing process and proper establishment of commercially available of PRP gel and easiest finding theway of it'sapplication.
