    Pig production plays an essential role in the food supply for both Hungary and Laos. In 2021, Laos had a pig population of approximately 4.3 million, with more than 90% indigenous pigs; meanwhile, the Hungarian pig population was about 2.7 million. Hungarian Mangalica pigs are well-known in the European region because of their unique fat and lean meat quality, but Moo Lath pigs (ML) are well-known only in Laos as self-sufficient production for rural revitalization. However, more consumers in Laos currently prefer consuming pork produced by ML pigs as they believe in their healthy meat and fat. The lack of scientific research on improving the reproductive performance and quality of ML pigs is challenging for Lao researchers. This study aims to improve the reproductive performance of Lao indigenous pig breeds using the successful experience of Hungarian experts with Mangalica evolution. Estrous synchronization “ES” (Altrenogest Regumate®) and artificial insemination (AI) were used to improve ML gilts’ litter size and piglets’ quality. Feeding strategies and housing management were used to improve the farrowing and lactation management methods for ML sows as our core experiment in Laos. The gilts in the group of ES and AI using Duroc semen produced 3 more piglets than gilts in the control group and more than one piglet than the non-synchronizing but artificially inseminated group. In contrast, piglets mummification occurred only in gilts from synchronized and non-synchronized groups but did not occur in the control group. Our results revealed that ML gilt’s uterine capacity cannot accomodate more than 8 fetuses. Interestingly, the F1-crossbred piglets’ birth weight and growth performance on day 28 were not improved compared to those in the control group, which is noteworthy. The optimal age at the first service of ML gilts is between 210 and 240 days (d), with a body weight (BW) of nearly 45 kg. However, cross ML x Duroc gilts can attain puberty at about 137 d and approximately 193 d at first mating, with a BW of about 39.69 kg and 38.18 mm of a backfat thickness (BF). The lactation length had an adverse effect on the body conditions of the ML primiparous sows, which began in week 4 and worsened by week 7. There was no difference in the weaning weight between ML piglets weaned at 28 or 35 d of age. Likewise, the piglets weaned at 35 or 42 d showed no difference. Similarly, in this study, there was no difference in weaning weight within weaning age; 42, 49, and 56. However, the weaning age did not influence the weight gain of ML piglets in the 1st week after weaning. But, in the 2nd post-weaning week, piglets with longer suckling periods gained nearly 3 times the weight gain compared to those with shortened periods. In brief, Lao farmers should keep in mind that ML piglets should be weaned at about 5 to 6 weeks to achieve the best economic return. Similarly, the optimal age of ML gilts at first mating should not be less than 210 d. Meanwhile, the body weight should not be less than 40 kg at their 3rd or 4th oestrous cycling. Utilizing Altrenogest Regumate® in ES and AI can improve the litter size of ML gilts, but the birth weight and body weight at day 28 of crossbred ML x Duroc piglets were not affected. The capacity of gilts’ uterine horns, small body weight at first insemination, and ML sows’ milk production are to be considered when addressing these issues. The actual Mangalica reproductive management and housing methods provide an excellent example for Moo Lath farming development in Laos.

    Perspectives of the livestock sector in the Philippines: A review
    (2021-06-01) Ortega, Arth David Sol; Mujitaba, Malam Abulbashar; Xayalath, Somsy; Gutierrez, Winson; Soriano, Ana Celina; Szabó, Csaba
    The Philippine livestock industry is a vital component in the country's agricultural sector. It contributes around 18.23 percent of the gross output value in agriculture and provides livelihood to many people living in rural areas, signifying its importance with regard to the country’s economy. The constantly increasing demand for animal protein associated with the increase of the world’s population led to the intensification of livestock production, realized through the various initiatives implemented by the government, such as the import of high producing purebreds of various species. This strategy greatly influenced the country's animal genetic resource's diversity and increased food animals' population; however, it impacted the native breeds of food animals. Understanding the characteristics, performance and value of native and exotic breeds is essential to prioritize their livestock industry existence. Thus, this paper aims to characterize various native and exotic breeds of livestock in the Philippines and assess the current conservation of native animals.

    A review on the trend of livestock breeds in Laos
    (2021-06-01) Xayalath, Somsy; Mujitaba, Malam Abulbashar; Ortega, Art David Sol Valmoria; Rátky, József
    When the livestock sector is considered an essential role in farmers' livelihood, and local breeds are still the critical component of animal breeding in Laos. Thus, there is a need to review the previous, current situation and prospects for Laos' livestock production. It aimed to study the different traits among the existing dominant local and improved livestock breeds (cattle, pig, and goat) and a more in-depth study on the livestock sector's previous evolving and prospects. Our findings revealed that the general trend of livestock population in Laos increased year-by-year for over 45 years, except for 1995 to 2000. It was decreased by almost 22% due to the new national strategy on economic revolution.  The first foreign breeds were introduced into Laos, i.e., Large White, Landrace, and Duroc in 1980, Red Sindhi bulls in 1998, the frozen semen of Red Brahman 2003, and Bach Thao goats between 2001 to 2003. Unfortunately, many data are still not precise for introducing other foreign breeds like Boer goats, Thai Grey and Red Brahman. There were many missing data on the improvement of livestock breeds in Laos, including the local and improved breeds' reproductive and productive performance, which needs more study and research. We conclude that the semi-complex farm operation should be applied to improve livestock breeding and their productions in Laos.

    The role of animal breeding with special regard to native pigs of food supply and rural development in Laos
    (2020-05-20) Xayalath, Somsy; Balogh, Eszter; Rátky, József
    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 products 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.
