Andrological examination of Hungarian Large White and Landrace boars
Published December 28, 2018
5-10

The Hungarian Large White and Hungarian Landrace pig breeds have outstanding lifetime performance, production parameters and crossbreeding ability. Nevertheless, during the recent decades, these breeds could not compete with the West European hybrid pigs concerning on production results. In this study, we made a complex andrological evaluation ...of boars in different Hungarian nucleus breeding stocks. After taking blood and semen samples, performing gonadotropin-releasing hormone (GnRH) challenge, ultrasonic and thermographic examinations were done. Laboratory tests were accomplished in reproduction labs of NARIC ABNMS. Our goal was to determine the reproductive performances of boars and collect samples for future genetic examinations, respectively.

The role of animal breeding with special regard to native pigs of food supply and rural development in Laos
Published May 20, 2020
149-154

The present paper explored the influence of breeding native pigs on livelihood conditions and the contribution of native pigs to the rural development and rural poverty reduction in the rural areas of Lao PDR. Pig production plays an important role in meat supply for both urban and rural areas of Laos. It is clear that most of the pig produ...cts in the country come from smallholder pig farms, and more than 90 percent of those products are the native pigs mostly raised by farmers in remote areas. In general, livestock production distributed between 15–18 percent to GDP, while most of animal production still remains as the traditional methods. Rural development is always the first priority of the Laos government since its independence in 1975, however, the poverty rate in rural areas remained high at 23% in 2018. It might block the development goal of the government which will lead the country out of the least development status by 2020. The food security and malnutrition in the rural or mountainous areas are considered as the majority issue that both government and several international organizations have been thriving hard to overcome, which researchers showed that more than 45% of children under 5 years of age were stunted, and 28% of them were underweight. Inspired of more than 50 % of the households in the rural areas of Laos reported they consumed chicken and pork at least one day a week. While native pigs play an important role on meat supply, it also constituted around 9–14 % of annual income of the households in rural areas. Therefore, the increase the production of pigs and poultry is one option to promote the meat supply to households in the rural areas of Laos. This paper will be a pathway to guide and identify for the final decision to what experiment will be implemented on Lao native pig in Laos (2021–2023) to complete the comparative study on reproductive physiology and reproductive management methods of Hungarian and Lao Indigenous pig breed. Which found it still needs further afford to research and improve more about native pig performance for all areas of productive and quality management.

Storage of ram semen in gelatin supplemented extender
Published July 31, 2012
7-10

The aim of our study was to examine how different gelatin concentrations affect ram semens viability in liquid storage at 5 oC for five days. Our hypothesis was if we add gelatin to the semen extender, than the viability of ram semen will be better in the extenders containing gelatin, than the control. We used two different semen ext...enders:1.5% UHT milk and 1.5% UHT milk + 5% egg yolk. We added 0; 0.5; 1.0; 1.5; 2.0% Dr. Oetker gelatin to the semen extenders. We stored the semen for five days at 5 oC and in every 24 hour we made sampling.
We stained the smears with Kovács-Foote staining and evaluated them with light-microscope. We categorized the cells in five groups like: live and intact cells, live cells with injured acrosome, dead cells, live head with dead tail and live tail with dead head. We used one-way analysis of variance (ANOVA) to assign how gelatin concentration affects the number of the categorized cells. On the fifth day, the viability was the best in the following semen extenders: 1.5% fat UHT milk + 1.0% gelatin and 1.5% fat UHT milk + 1.5% gelatin, but it was not significant (p>0.05).
