4.1. Animal Husbandry
Meat from domestic animals seems to have been one of the main sources of proteins for the discussed communities. Both assemblages are dominated by the remains of small ungulates, i.e., pigs and sheep/goats, while large ungulates such as cattle and horses made up a small percentage of the identified species.
The amount of pig bone fragments was the highest in both settlements; therefore, it can be inferred that pork might be the main source of meat for the discussed communities. However, this proportion may change when considering how much meat could have been produced by slaughtering larger and smaller ungulates. For example, Lyman’s [
41] calculation of the meat from slaughtered pigs (MNI 21) would yield about 580–620 kg, while the meat from cattle alone could have yielded 1400–2000 kg. However, it is likely that Lyman’s weight for Lithuania animals is too high. Using other estimates [
42,
43,
44], pigs could be expected to yield as little as 1400 kg and cattle about 1050 kg. However, further consideration of this issue requires more detailed osteometric and taphonomic studies. In Garniai 1 and Mineikiškės, two same-pig-age groups appeared; animals aged from 6 to 12 months and 1.5 to 2 year old animals. These appear to be spring-born individuals that were slaughtered before the first and second winters. As pigs were mainly kept for the meat, the majority of them were slaughtered as soon as they reached their maximum body weight. If these animals were kept over the winter, the lack of food would cause them to lose all the weight they had obtained [
45].
Pigs are dominant not only in Garniai 1 and Mineikiškės but also in multi-period sites in Eastern Lithuania. Most of the investigated material from Antilgė, Narkūnai, Nevieriškė, and Sokiškės fortified settlements was dated from LBA toRoman Iron Age; thus, it seems that pigs were important in the economy of communities living in this area over a long time. Looking at the higher frequencies of pig bones, Eastern Lithuania is distinctive from the rest of the areas in the Eastern Baltic region (
Table 11). In all investigated cases, the bones of these animals were not found in higher amounts than 25% of all identified species [

50,
51].
Sheep/goats were the second most abundant group of domestic animals in the Garniai 1 and Mineikiškės fortified settlements. As the communities in these sites obtained most of their meat from pigs, it is possible that the role of sheep/goats in the household was more diverse. Secondary products in the community may have been used, but it is not possible to determine for what specific purpose, milk or wool, the sheep/goats were kept. Only four animals were identified at the Garniai 1 site, with an age ranging from 10–12 months to more than four years, so it is impossible to say whether sheep/goats were bred in this site for particular specific activities. In Mineikiškės, two general age groups were distinguished (1.5–2 yrs and 2–4 yrs). It is likely that individuals aged 1.5–2 years may have been reared for meat production. Some researchers suggest that this is the most optimal time to slaughter sheep/goats because, at this age, individuals, especially males, reach their weight gain peak; therefore, if no other functions in the household were required, there was no need to keep them for a longer time [
52,
53,
54]. Older animals, such as those of 2–4 years and over four years of age, may have been kept for breeding and for secondary products.
In Estonia, Saaremaa Island, the pig and sheep/goat abundance is ca. vice versa that of the assemblages from Eastern Lithuania. In the Asva and Ridala fortified settlements, sheep/goats were the most frequently (25.6–37.1%) reared animal, while the second most abundant group was pigs [
50]. Meanwhile, in other LBA settlements in the eastern Baltic, sheep/goat numbers were distributed differently (
Table 11). In several sites, they accounted for only 6.7–7.6% of all identified specimens, in others 17.1–19.1% [
46,
47,
48,
49,
51].
The number of cattle bone fragments found in the analysed sites was significantly lower; it is possible that cattle were very important, just not kept in large numbers, as they were so expensive to keep. Some researchers point out that cattle may have been an important exchange commodity between nearby or distant communities. Rare cattle may have been valued for their large quantities of meat production and functionality, as they had several uses in the household, including ploughing, and the production of dairy products [
54,
55,
56].
The age of cattle found in the settlements varies, and they appear to have been reared and kept both for meat production, secondary products, manure, and as draught power. Three individuals aged 2–3 years were found in both sites; it is likely that they were traditionally slaughtered at this age for meat. This practice is also prevalent in medieval societies when young cattle of 8–18 and 18–30 months of age were slaughtered [
57,
58,
59]. A few skeletal remains of older adult individuals of 5–6 and 8–9 years old were also found in Garniai 1 and Mineikiškės. It is more likely that older animals were used for dairy products and work. The indication that cattle from Mineikiškės could be used as draught animals is the metacarpal bone with exostoses on the distal part (
Figure 3). This type of pathology often occurs when the animal is exposed to heavy loads [
60,
61]. However, exostoses on the lower limb of cattle can occur not only as a result of high stress during work but also due to the age of the animal, soil characteristics, genetics, and other reasons [
60]. The demand for dairy products in the community would be indicated by the increased number of bones of older females [
62]; however, due to the fragmented zooarchaeological material in these settlements, it is hardly possible to observe such trends at present.
In the neighbouring countries of the Eastern Baltic region, the number of cattle is considerably higher than in northeastern Lithuanian sites (
Table 11). For example, the ratio of cattle is below 20% of all identifiable species in Ridala, Asva, and Krievu kalns, while in other fortified settlements it ranges from 29.4–35.8% [
46,
47,
48,
49,
50,
51]. Moreover, cattle were the most prevalent domestic animal in the western Lithuanian sites, which probably indicates that cattle breeding played a significant role in local agricultural communities, possibly due to their role as draught power and a source of manure. This could also suggest the relatively increased importance of agriculture in western than in eastern Lithuania [
7].
Horse bone fragments are the least frequent domestic mammal in the analysed zooarchaeological material; therefore, it seems that the meat of these animals was not of high importance to human nutrition. However, in neighbouring regions, it seems likely that horse meat may have formed a larger part of the diet of these communities (
Table 11). In Asva and Ridala, the number of horses was very low, but in other settlements, it varied significantly at higher ratios, i.e., from 11.5 to 30.2% [
46,
47,
48,
49,
50,
51]. However, horse bones comprised the second largest or even the largest portion of the recovered zooarchaeological material in western Lithuania and Latvia during the LBA, Roman Iron Age, and Migration period [
7].
Unsurprisingly, horse remains contained butchering marks, suggesting their meat was used for food. Due to the limited and fragmentary nature of the Mineikiškės and Garniai 1 assemblages, it is difficult to assess whether the horse skeletal remains belonged to wild or domestic animals. Some researchers believe that domestic horses were present in Lithuanian territory from the Late Neolithic to the Early Bronze Age [
63]. However, it should be noted that wild horses were still hunted by the local population from as late as 16 to 17 C AD in the territory of Lithuania, Prussia, and possibly western Latvia [
64,
65]. The small number of bones and the age structure suggest that horses were not used as an important source of food for these communities. The skeletal remains of horses found in both fortified settlements belonged mainly to individuals ranging from young adults to the elderly. It is likely that they first functioned as a workhorse and were only slaughtered when they were no longer able to function in that way. A few exceptions are one yearling and one 2–3 year old horse, found in the Mineikiškės hillfort. The reason for slaughtering these animals might be due to illness or food shortages, or they might have been hunted wild animals.
4.2. Hunting, Fishing and Gathering
Bone fragments of small fur-bearing animals (e.g., hares, foxes) predominate among the wildlife remains, accounting for 87.0–96.1% of all identified game animals. Bones of large game were rare in both settlements. Foxes were mainly represented by the lower limb bones and mandibles, the latter usually bearing cutting marks. Meanwhile, among the bones of hares, the tibia, femur, humerus, and radius were the most common. Therefore, hares, as expected, were mainly hunted for meat, while foxes seem to have been hunted only for their fur. Very few bones from other furbearers (mustelids, otter, red squirrel) were used to draw more reliable conclusions about their use.
Large game accounted for only 3.9–13.0% of all the analysed wild animals. The diversity of species is slightly wider in Mineikiškės while, in Garniai 1, only two bones were found, belonging to a wild boar and bear. The lower number of large wild animals in Garniai 1 seems to be due to the size of the assemblage. The low quantity of large wild animal bones in both settlements and their anatomical distribution could be due to the fact that the large game was butchered in the kill sites instead of the habitation area, and the hide of the animal was used as a container to transport the meat back to the settlement. The meat appears to have been removed from the forequarters and hindquarters and the bones discarded, while feet were left attached to the hide and used as handles to drag the meat-filled skin [
66].
Hunting significantly declined in this area from Neolithic to LBA as the community became more involved in other sectors of the economy, such as animal husbandry and crop agriculture. Livestock became the main source of meat. The bones of domestic animals were one of the most available resources for the production of tools, weapons, and parts of garments. Wild animals were more likely to be hunted in case of food shortages and for secondary products such as fur. Although wild animal remains make up a very small proportion of the total number of bones identified in the Garniai 1 and Mineikiškės, the situation was different in some other areas of the Eastern Baltic region (
Table 11). While in Brikuļi and Ķivutkalnis (Latvia), wild animals made up a small percentage of the material identified [
46,
48], in other settlements such as Asva, Ridala (Estonia, Saaremaa Island), Krievu kalns and Vīnakalns (Latvia), the skeletal remains of game ranged between 21.2 and 41.9% of the total number of identifiable species [
46,
48,
49,
50,
51]. Thus, the subsistence strategies varied in the Eastern Baltic region, as some communities practiced more active hunting during the LBA.
Mollusc remains account for 6.2% of the total analysed material. Molluscs, like wild animals, could have provided an additional source of protein for the communities in times of food shortage [
67]. These are the first settlements in Lithuania where mollusc remains were found in such large quantities. A few mollusc shells were also found in the Narkūnai hillfort (identified recently in the National Museum of Lithuania), but due to the position of the finds from LBA–medieval periods in the same strata of this site, it is not possible to determine the specific time period of the mollusc remains. In addition, sieving was not used in Narkūnai, so in most cases, the fine shells may simply not have been collected. In fact, mollusc remains are very rare in zooarchaeological assemblages from all periods not only in the territory of Lithuania but also in the whole Eastern Baltic region. A large number of molluscs was found in northern Latvia, in the Subneolithic settlement of Riņņukalns [
68]. Large quantities of mollusc remains were also found in several Neolithic settlements in Estonia (Narva Riigiküla and several settlements along the Narva River) [
68].
All the fish species found in the settlement, except for the chub, like to live in lakes or slow-moving rivers. Only the chub prefers more flowing rivers. It can, therefore, be assumed that the local community mainly fished in the slow-moving river near the site or in nearby lakes. Among fish remains, 63.3% of the fish bones were cranial elements, with the remaining 16.0% of shoulder grids and 20.1% of vertebrae and, as mentioned above, a significant number of scales were found. This anatomical composition of the fish bones, with a particularly high proportion of cranial bones, suggests that both small and large fish were likely to have been filleted locally, and the bones that were found may be both fish processing and eating waste. The quite abundant fish remains also can be related to food shortage. However, this can be linked to the excavation technique or small excavated areas.
Only a few fragments of bird bones were found, all of which were not identified. However, the importance of wild poultry in the human diet was likely minimal.
