“…Entretanto, outros autores afirmaram haver efeito da raça da matriz no peso dos leitões e da leitegada ao nascer (NOCERA & FEDALTO, 2002;FRAGA et al, 2007). E, efeito da ordem de parto da fêmea no peso da leitegada ao nascimento (NOCERA & FEDALTO, 2002;LIMA et al, 2006) PINHEIRO et al, 2000;NOCERA & FEDALTO, 2002;LIMA et al, 2006;GIACOMELI et al, 2010;RAZMAITE et al, 2012). Contudo, essa resposta não foi observada no presente trabalho.…”

<p>O objetivo com este trabalho foi avaliar o efeito de grupo genético (GGen) e de ordem de parto (OrdP) de 400 matrizes suínas sobre características produtivas e reprodutivas. Utilizou-se três GGen (GGen1, GGen2 e GGen3) e duas OrdP (OrdP1 e OrdP2). As variáveis dependentes avaliadas foram peso médio da leitegada ao nascimento (PMNasc), peso médio da leitegada ao desmame (PMDesm), tamanho da leitegada ao nascimento (TNasc), tamanho da leitegada ao desmame (TDesm), duração da lactação (DL), número de partos/fêmea/ano (P/F/A), número de leitões desmamados/fêmea/ano (D/F/A), ganho de peso diário do leitão (GPD), ganho de peso diário da leitegada (GPDLeit), intervalo desmame-cio (IDC), média de dias não produtivos (MDNP) e número de serviços por concepção (NSPC). A interação entre GGene OrdPfoi significativa para PMDesm, DL, P/F/A, GPD, IDC e MDNP. Para as demais variáveis (PMNasc, TNasc, TDesm e D/F/A) não ocorreu interação nem efeito de GGen e OrdP. Houve efeito do GGen independente da OrdP nas variáveis GPDLeit e do NSPC. O GGen 3 foi considerado superior, uma vez que este apresentou melhor desempenho em relação aos demais na maioria das características avaliadas. Não foi possível determinar a melhor OrdP, pois esta variou em função dos GGen e das variáveis dependentes.</p>

“…The basic data obtained on reproductive traits in this review are presented in Table 3. Sows of Lietuvos vietinė pig breed have 7.2-9.7 piglets [1-3] of approximately 1.3 kg live body weight [1][2][3][4]. Stillborn percentage of piglets is in between 7.4 and 16.1% [1,3], whereas piglet mortality rate until weaning in the considered studies varied between 14.6 and 31.1% [2,3].…”

Duration of lactation is prolonged in comparison to modern intensive systems (to approximately 59 days [1,3,4]), which leads to a higher piglet weaning weight (around 14 kg [1,3,4]).…”

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 agrobiodiversity, 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. Meat quality traits of the longissimus muscle were evaluated by means of pH at 45 min and 24 hours after slaughter.

“…The age of sows of Lietuvos Baltosios senojo tipo pig breed at the first parturition is 14 [3]. They have 9.6-10.4 piglets per litter [1,3,4] of approximately 1.3 kg live body weight [2,3,5]. Stillborn percentage of piglets is in between 7 and 8% [1,4], whereas piglet mortality rate until weaning in the considered studies was 10.8 and 19.7% [3,4].…”

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.
