Abstract

Microalgae Spirulina platensis accumulates many chemical components which are suitable for all higher organisms as food and forage raw material. There are a lot of vitally important for the organisms minerals and macroelements such as iron, calcium, sodium, potassium, copper, magnesium, phosphorus, selenium, vitamins, carotin, nucleic acids, enzymes and other active substances. That should explain the value of Spirulina as a feed additive for the agricultural animals. In the present work the influence of the microalgae Spirulina platensis on the quantitative and qualitative characteristics of boars' sperm was studied. The experiment was carried out with 6 boars from Danube white breed in the experimental animal base of the Agricultural Institute - Shumen. The time of the experiment was divided in the control and experimental periods. During the control period the animals received the main diet in accordance with Bulgarian state standard BDS- 1642-96. In the experimental period to the main diet was added 7 ml/ per head the fresh biomass of microalgae preserved by melasa (final quantity - 1,4 mg Spirulina platensis). The obtained results shown that the addition of Spirulina improves the sperm parameters in boars: the volume of the ejaculates increased with 30 ml in experimental period (306 ml against 276 in control, P<0,05) as well as the spermatozoa concentration enhanced with 27 mln/ml. The total dehydrogenases activities estimated by reaction with methylene blue as well as LDH activity were higher in the experimental period. Also the survivability of the spermatozoids at 24, 48 and 72 hour in the experimental period was more than in control.

Highlights

The use of AI in swine breeding will continue to increase and in the future, most swine producers will employ this technology

Summary

Introduction

The use of AI in swine breeding will continue to increase and in the future, most swine producers will employ this technology. The most part of semen utilized in AI programs is in a liquid (fresh) form and is utilized within several days after collection It has been well-demonstrated that farrowing rates and litter sizes achieved using liquid semen can be equal or better than those resulting from natural mating systems (Flowers and Alhusen, 1992). The insemination with frozen semen generally results in low fertility and fecundity (Szczęśniak-Fabiańczyk et al, 2003). In this case is very to obtain the boars semen with high quality parameters and good fertilizing capacity. During the last years in accordance with the development of biological farm system the producers have been looked for the natural active compound for the improvement of the reproductive performances of live stock animals. According to the Rudic et al (2008), the administration of the BioR injectable solution induces the increasing of the ejaculate volume (up to 25%), provides an increasing of the concentration and spermatic cell density (up to 20%) and intensifies the sperm mobility (up to 30%) in the sire bulls and boars
