Pre-weaning piglet mortality represents significant economic losses, and approximately half of this occurs within the first 3 days after birth. Factors involved in postnatal can also be associated with a poor growth performance until weaning. The aim study was to evaluate effect some variables measured right birth on survival during week life Piglets included analysis (n=612) were born from 5 parity sows. monitored for blood oxygen saturation (SatO2), heart rate (HR), glucose concentration,...
The aim of this study was to evaluate the influence sow body reserves at weaning and reserve losses during first lactation on second litter size (SLS). A number 1222 females which reached parity without failures such as return estrus after insemination, abortion or failure farrow, were analyzed. Measurements weight (BW), backfat thickness (BT) condition score (BCS) taken within 24 h farrowing day. Body fat protein mass their estimated based BW BT. length, weaning-to-estrus interval (WEI)...
Contents This study was carried out to evaluate the effects of sperm cell dose and semen backflow on pregnancy rate number embryos sows inseminated once at 0–24 h before ovulation, using an intrauterine technique. The results were analysed from a total 211 assigned three groups with doses 0.25 × 10 9 (T1), 0.5 (T2) 1.0 (T3) spermatozoa. Semen observed in 95% females (143/151) evaluated for this purpose. percentage is close two‐third volume around 15% infused dose. Intrauterine insemination...
Cross-fostering is the transference of piglets to equalise litter size according birth weight. In many commercial farms are usually grouped in litters with 100% adopted piglets. The aim experiment was assess behaviour during suckling period as well their performance and mortality rate up weaning different composition terms biological Three treatments were studied: 100B (100% piglets, n=13), 50B50A (50% 50% n=13) 100A n=13). All standardised eleven on average within 20.1±0.4 h (14.3–24.7 h)...
It is commonly known that large litter size leads to lower average birth weights, with more piglets born weighing <1 kg, resulting in a negative impact on piglet growth performance. Conversely, there are few studies showing the long-term of low weight productive performance female selected for breeding herd. The aim this study was evaluate effects reproductive and longevity up third farrowing Landrace x Large White crossbred gilts. For most variables, 835 gilts were included analyses. When...
The present study assessed the association of tail-biting lesions in finishing pigs with weight gain, occurrence locomotion or respiratory disorders and abscesses during period, carcass condemnation at slaughter. was carried out on 4 different farms. For each animal a tail biting lesion, two control were selected. total number animals 312, 104 them being tail-bitten. Tail classified according to degree severity into four scores: score 0 -normal withou lesion; 1-3 - increasing lesion...
Journal Article Impact of feed intake during late gestation on piglet birth weight and reproductive performance: a dose-response study performed in gilts Get access André L Mallmann, Mallmann Departamento de Medicina Animal/Faculdade Veterinária, Universidade Federal do Rio Grande Sul, Porto Alegre, Brazil Search for other works by this author on: Oxford Academic PubMed Google Scholar Elisar Camilotti, Camilotti Deivison P Fagundes, Fagundes Carlos E Vier, Vier Ana Paula G Mellagi, Mellagi...
Sex determination of in-vitro matured/in-vitro fertilized ovine embryos cultured in synthetic oviduct fluid (SOF) medium was performed by the polymerase chain reaction amplification specific Y DNA sequences so as to test influence sex on developmental growth during preimplantation period. At 144 h post-insemination, with a blastocoel were classified fast-developing group, whereas those showing only after this length time slow-developing group. separately and some according size their...
Contents The study evaluated the reproductive performance of primiparous sows submitted to post‐cervical insemination ( PCAI ) compared with cervical artificial CAI ). Difficulty catheter introduction, occurrence bleeding or semen backflow during insemination, and volume sperm cell up 60 min after were also evaluated. Sows homogenously distributed, according body weight loss in lactation, lactation length, weaned piglets, weaning‐to‐oestrus interval total born previous farrowing, two...
The aim of the study was to evaluate influence different temperature control systems on voluntary feed intake (VFI), percentage weight loss (PWL) and performance lactating sows as well their piglets. Two were used: traditional system (TTCS) with curtain management an evaporative snout cooling (ESCS). performed during summer 2011. After farrowing at weaning, 241 weighed PWL lactation. TTCS lost more (5.3±0.9%; P<0.05) than ESCS (2.2±0.9%). VFI measured intervals four days in 32 primiparous...
The increase in the litter size past decades has caused reduction individual piglet birth weight. Therefore, nutritional strategies employed last third of gestation order to improve weight have been studied. This study aimed evaluate effects 2 different feeding levels (1.8 and 2.2 kg/d) on female reproductive performance. A total 407 females were fed a diet based corn-soybean meal (3.25 Mcal ME per kg 0.65% standardized ileal digestible lysine) from day 90 until farrowing. weighed 112...
The development and quality of ovine zygotes matured fertilized in vitro were compared after coculture with oviductal cells (CZB–199 system) culture synthetic oviduct fluid medium without (SOF system). effect two oxygen concentrations (5% 20%) on the SOF was also studied. More reached blastocyst stage when performed 5% O2 rather than 20% O2. A greater number blastocysts obtained system CZB–199 system. Proportions grade I (excellent), II (good), III (fair) IV (poor) did not differ...
The aim of this study was to evaluate the reproductive performance gilts that had a similar age but different weights at onset puberty stimulation by boar exposure 144 days. Gilts were divided into two groups according their lifetime growth rate from birth approximately days age. Mean rates moment 577 and 724 g/day for group 1 (G1; n = 58) 2 (G2; 58), respectively. After selection, weighed 155, 165 175 age, on insemination day slaughter. inseminated, average, 193 slaughtered 32 after...
