Lietuvos Baltosios Senojo Tipo (Lithuanian White) Pig
Lietuvos Baltosios senojo tipo pigs are remaining purebred pigs of local Lithuanian pig breed (Lietuvos Baltosios) adapted to the specific local environment and locally available feedstuffs. Although previously Lietuvos Baltosios was the main dam pig breed in Lithuania, regarding scientific substantiation, their performances and products are, as in the case of Lietuvos Baltosios remains (senojo tipo-old type) pigs, practically untapped. Thus, the present chapter aims to present history and current status of Lietuvos Baltosios senojo tipo pig breed, its exterior phenotypic characteristics, geographical location, production system and main products from this Lithuanian breed of pigs, one of the local pig breeds investigated in the project TREASURE. Moreover, a collection and review of available literature data, available until August 2017, on reproductive and productive traits of Lietuvos Baltosios senojo tipo pig breed were carried out. Reproductive and growth performance, and feed intake in different stages was estimated. Lean meat content was measured by ultrasonic equipment Piglog on the side of live pigs at the position of 12 ribs. Measurements of backfat thickness were taken with a ruler on the left side of carcasses at dorsal line of the mid-back at the last rib and loin area at the 1/2 lumbar vertebra by digital camera EX-Z110 and, afterwards, were planimetrically measured by means of the “SCAN-STAR K” planimetrical system. Meat quality traits of the longissimus muscle were evaluated using pH at 45 min and 24 h after slaughter, objective colour (CIE L*, a*, b*) and intramuscular fat content.

Lietuvos Vietinė (Lithuanian Indigenous Wattle) Pig
Lietuvos vietinė pigs were developed in Lithuanian ethnic lands following natural selection and introduction of some imported pigs. Earlier, no purposeful selection was carried out for this old Lithuanian pig breed. Lietuvos vietinė pigs as other local pig breeds are adapted to the specific local environment and could be fed with various locally available feedstuffs. So besides their genetic merit for agro-biodiversity, they represent the basis for sustainable local pork chains. The present chapter aims to present history and current status of Lietuvos vietinė pig breed, its exterior phenotypic characteristics, geographical location, production system and main products from this Lithuanian autochthonous breed of pigs, one of the local pig breeds investigated in the project TREASURE. Moreover, a collection and review of available literature data, available until August 2017, on reproductive and productive traits of Lietuvos vietinė pig breed were carried out. Reproductive and growth performance was estimated in different stages. Lean meat content was measured by ultrasonic equipment Piglog on the side of live pigs at the position of 12 ribs. Measurements of backfat thickness were taken with a ruler on the left side of carcasses at the dorsal line of the mid-back at the last rib and loin area at the 1/2 lumbar vertebra by digital camera EX-Z110 and afterwards were planimetrically measured by means of the “SCAN-STAR K” planimetrical system.
