Changes in adipose cells of Longissimus dorsi muscle in Iberian pigs raised under extensive conditions Anais da ABC (AABC)
AYUSO,DOLORES; GONZÁLEZ,ANA; PEÑA,FRANCISCO; IZQUIERDO,MERCEDES.
ABSTRACT Twenty-four Iberian castrated male pigs were used to characterize and evaluate the effect of the duration of “Montanera” in the adipocytes size and its relation with the backfat thickness and intramuscular fat. The animals were fed under extensive conditions during 30, 60 and 90 days in the “Dehesa” before slaughtered. Carcass weight, percentage of intramuscular fat, thickness of backfat and its three layers and adipocytes size of the intramuscular fat were obtained. The group which expended 90 days on fattening obtained the highest adipocytes, with an area higher by a 50% than those that only expended 30 days. The differences in diameter and perimeter adipocyte were not as marked as area. A significant positive correlation between the diameter,...

Relationship among body condition at parturition, decrease of backfat thickness and weight during the lactation and the interval from weaning to oestrus of sows Braz. J. Vet. Res. Anim. Sci.
GUEDES,Roberto Maurício Carvalho; NOGUEIRA,Raimundo Hilton Girão.
The main objectives of this study were to verify the relationship among body condition at parturition, decrease of backfat thickness and weight during the lactation and the interval from weaning to oestrus of sows. It was performed with 10 gilts and 10 fifth, sixth and seventh parity Camborough sows. The average breeding age and weight of the gilts were respectively 231 days and 149.5 kg. During lactation all females were fed a wet diet (3.34 Mcal/kg, 17% CP), ad libitum. The average daily food consumption was 5.233 for gilts and 5.721 kg for multiparous sows. Ultrasonic measurements of backfat at the P2 site were recorded on day 6 before and days 2, 7, 14, 21 and 25 after parturition. Body weight was recorded on the same dates, except the day before...

Genetic trends in the performance and reproductive traits of pigs Genet. Mol. Biol.
Torres Filho,Rodolpho de Almeida; Torres,Robledo de Almeida; Lopes,Paulo Sávio; Pereira,Carmen Silva; Euclydes,Ricardo Frederico; Araújo,Cláudio Vieira de; Silva,Martinho de Almeida e.
The selection and evaluation of breeds and purebred lines to be used as the parental stock is an important step for the success of any animal breeding program. In this study, the feed:gain ratio, backfat thickness corrected for 100 kg, age to 100 kg, average daily gain, and age of sow at first farrowing were used to evaluate the genetic trends for direct and maternal additive genetic values in Large White pigs. The total number of piglets born or born alive and the litter weight at birth were used as indicators of the genetic trends for the direct additive values. The genetic trends were calculated by regression of the average predicted genetic values per year for each trait versus the offspring's year of birth (for performance traits) or versus the dam...

Growth and reproductive performance of 14- to 15-month-old Hereford heifers R. Bras. Zootec.
Landarin,Carolini Machado; Lobato,José Fernando Piva; Tarouco,Adriana Kroef; Tarouco,Jaime Urdapilleta; Eloy,Lidiane Raquel; Pötter,Luciana; Rosa,Antônio Augusto Galarza.
ABSTRACT Aiming at breeding heifers with 14-15 months of age, 100 Hereford calves were subjected to different feeding systems. Heifers grazed on a natural pasture in early winter, fed or not a supplement (14% crude protein; 72% total digestible nutrients), were transferred to a ryegrass pasture for 73 days, and then returned to a natural pasture for 15 days until the beginning of the breeding season. During the last 15 days on ryegrass pasture and the 15 days of the return to the natural pasture, half of the heifers of the two previous systems were offered the supplement, thereby establishing four feeding treatments. Heifers supplemented during the second period, independently of supplementation during the first grazing period, presented higher average...

Additional feeding during late gestation improves initial litter weight of lactating sows exposed to high ambient temperature R. Bras. Zootec.
Choi,Yo Han; Hosseindoust,Abdolreza; Kim,Min Ju; Kim,Kwang Yeol; Lee,Jun Hyung; Kim,Young Hwa; Kim,Jin Soo; Chae,Byung Jo.
ABSTRACT The present study investigated the impacts of additional feeding (AF; containing 16% excess feed than control diet in the last two weeks of gestation) during late gestation period and different backfat thickness (BFT) including low (<20 mm) and high (≥20 mm) backfat on reproductive performance, litter size, blood metabolites, hormonal profiles, colostrum, and milk composition of sows from day 90 of gestation to farrowing, and from farrowing to weaning during summer (average 28.3 °C). Fifty-four crossbred sows (Yorkshire × Landrace) were allotted to one of four treatments according to a 2×2 factorial arrangement. There was no AF×BFT interaction for any of the measured variables. The body weight change of sows was decreased for <20 mm in BFT...

Carcass traits and short-chain fatty acid profile in cecal digesta of piglets fed alfalfa hay and fructooligosaccharides R. Bras. Zootec.
Rodrigues,Daniela Junqueira; Budiño,Fábio Enrique Lemos; Prezzi,Joel Alberto; Monferdini,Renato Pacheco; Otsuk,Ivani Pozar; Moraes,José Evandro de.
ABSTRACT The objective of this study was to evaluate the effects of the addition of the prebiotic fructooligosaccharide and/or alfalfa hay to piglet diets on carcass traits and short-chain fatty acid profiles in the cecal digesta. Seventy-two commercial crossbred piglets of both sexes, with an average initial weight about 6 kg and age of approximately 21 days, were distributed in a randomized block design, using a factorial scheme, which consisted of three alfalfa hay levels (0, 5, and 10%) and two fructooligosaccharide levels (0 and 0.3%). Fiber addition in the presence of the prebiotic exerted an effect on cecal digesta short-chain fatty acid, increasing the acetic and reducing the butyric acid concentrations. The meat quality was also affected by the...

Silva,Saulo da Luz e; Titto,Evaldo Antonio Lencioni; Leme,Paulo Roberto; Martello,Luciane Silva; Pereira,Angélica Simone Cravo; Titto,Rafael Martins; Nogueira Filho,José Carlos Machado; Luchiari Filho,Albino.
There is a paucity of information in the literature on body composition changes in Nellore cattle and its crosses, mainly on heifers and intact males. Ultrasound is a useful, low cost tool to easily obtain this information, with minimal animal stress. Effects of sex and days on feed on live weight (LW) and ultrasound Longissimus muscle area (ULMA) and subcutaneous fat thickness (UFAT) measurements were evaluated in F1 Piedmont <FONT FACE=Symbol>´</FONT> Nelore, 27 heifers (HF) and 27 intact males (IM). HF and IM had an initial LW of 256 ± 5.6 and 265 ± 5.6 kg, respectively, and were fed a diet containing 77% TDN for 131 days. LW, ULMA, and UFAT were evaluated at 28-d intervals. Interactions between sex and days on feed were found for all traits...
