Effective Vaccinations
Posted in: Welfare by admin on January 1, 2006 | No Comments
Vaccinations are used to give the body an idea of what a disease looks like. From there, the body will be able to recognize when the infectious agent enters the body and the immune system will be faster to respond. Specific vaccinations can be required for different operations. Killing the infectious agent or making it unable to cause disease makes vaccinations. From here administration amounts and methods are tested and designated, and should be followed strictly. Vaccinations are important for gestating sows in that they equip them with antibodies that can be passed on to their offspring via colostrum. Note that vaccinations should be given at least 3 to 4 weeks prior to exposure, and some require booster shots later on.
Quantitative trait loci mapping for fatty acid composition traits in perirenal and back fat using a Japanese wild boar · Large White intercross
Posted in: Welfare by admin on | No Comments
Here, we analysed quantitative trait loci (QTL) for fatty acid composition, one of the factors
affecting fat quality, in a Japanese wild boar · Large White cross. We found 25 significant
effects for 17 traits at 13 positions at the 5% genome-wise level, of which 16 effects for 12
traits at 10 positions were significant at the 1% level. QTL for saturated fatty acids (SFA) in
back fat were mapped to swine (Sus scrofa) chromosomes (SSC) 1p, 9 and 15. QTL for
unsaturated fatty acids in back fat were mapped to SSC1p, 1q, 4, 5, 9, 15 and 17. Using a
regression model that fits back fat thickness as a covariate, two of the QTL for linoleic acid
content on SSC4 and SSC17 were not significant, but one QTL for total SFA composition
was detected on SSC5 with correction for back fat thickness. Wild boar alleles at six of seven
QTL tended to increase SFAs and to decrease unsaturated fatty acids. QTL for fatty acid
composition in perirenal fat were mapped on SSC2, 3, 4, 5, 6, 14, 16 and X. QTL for melting
point (in back fat samples) were mapped on SSC1, 2 and 15. Wild boar alleles in QTL on
SSC1 and SSC15 were associated with elevated melting points whereas those on SSC2 were
associated with lower melting point measurements.
Does floor heating around parturition affect the vitality of piglets born to loose housed sows?
Posted in: Welfare by admin on | No Comments
The most critical period for the survival of piglets is during the first 2 days of life. Causes of early piglet mortality include reduced vitality due to hypoxia during parturition, hypothermia and lack of adequate colostrum intake. Besides, low vitality piglets may run a larger risk of being crushed by the sow. However, these causes of death often seem to be triggered by an inadequate thermal environment postnatally leaving the piglets at risk of hypothermia. Hypothermic piglets are less vital and their chances of getting access to the udder and avoiding the movement of the sows are thus reduced (Herpin et al., 2002). This may be even more difficult for piglets in loose housing systems due to the possibility of the sow moving around in the pen. In the light of the thermoregulatory challenges facing newborn piglets and the possible sow-piglet interactions under loose housing, we investigated whether floor heating around parturition affected early piglet vitality and behaviour related to survival. Twenty-three Landrace x Yorkshire sows of 2nd parity were housed individually in 7.5 m² pens in a climate controlled facility. HEAT sows (n = 12) were exposed to pen floor heating (33.5 8C) from 12 h after onset of nest building and until 48 h after birth of 1st piglet, whereas CONT sows (n = 11) received no floor heating (21.2 8C). The concentration of lactate in umbilical cord blood at birth—an indicator of hypoxia—increased with the birth duration (P < 0.001) and with declining piglet weight (P < 0.001), with no significant effect of floor heating. After the initial drop in body temperature at birth, floor heating resulted in an earlier recovery of piglet temperatures (P < 0.001), i.e. the piglet’s period for experiencing hypothermia after birth was reduced. HEAT piglets also suckled sooner than CONT piglets after the 1st hour post partum (with ratios between HEAT/CONT hazard functions being 2.9–6.4 for latency to suckle in the period 1–3 h after birth). Moreover, fewer live-born piglets died during the first 3 days (P = 0.047), as well as during the first week in the floor heated litters (mean (S.E.) HEAT 8.7 (2.8)% versus CONT 15.5 (5.2)%, P = 0.014). We did not find any effect of floor heating on duration of parturition, inter-birth intervals, litter size, early piglet weight gains, blood glucose and lactate concentrations at birth, heart rate at birth, piglet activity from birth to first suckling or amount of parvovirus antibodies transferred from sow to piglets. In conclusion, floor heating around parturition had no evident effect on the innate piglet vitality, but it had favourable effects on the early recovery of piglet body temperature, latency to first suckle and survival of piglets in the loose house system.

Measuring Performance and Maximizing Throughput In the Finish Phase
Posted in: Production by admin on | No Comments
Techniques of the Hanor Company are discussed in regard to monitoring key production indicators of the finisher barn. Information keeping is important in 6 key areas: 1) Daily/Weekly Reporting (death loss, inventory, etc.); 2) Close-out reporting (growth, death loss, feed conversion, etc.); 3) Top Hog Marketed Index; 4) Market Result Report; 5) Feed; 6) Finances.
China – Pork Powerhouse of the World
Posted in: Production by admin on | No Comments
In recent years, live pig and pork production and pork consumption have been undergoing dramatic changes in China. As the biggest pig and pork producing country in the world, all these changes will not only influence the pig and pork industry in China, but will also affect international feed and pork trading countries. An overview of the current status and challenges faced by China will help the world understand the past, present and future trends in the Chinese pig industry. This information may also enable countries and companies to adjust pork production policies to suit the future international market economy in pork. China has an abundance of labour but is running out of land and resources. There is a lower pork price but high cost for major agriculture products. As a pork powerhouse, China will influence all aspects of the world pig industry such as labour, feed ingredient trading, food processing, pork trading, live pig trading, equipment and technology transfer. More strict measures are required to limit small-scale operations to improve meat safety and international competition. China can be expected to continue its role as a pork powerhouse of the world. The present pattern of increases in productivity, lean yield and carcass weight will continue. Rather than becoming a new export market for existing pork producing countries, China will probably become a major international competitor in the pork export market.
GO TO THE MASTERS WITH GROW-FINISH F:G AND ADG
Posted in: Production by admin on | No Comments
Factors that Affect GF Performance are health, genetics, nutrition (energy, dietary lysine level), feeder pig weight, barn design and gender. Economic summary assumes the following: total grow-finish cost = $55 / pig; facility cost = $0.10 / pig / day; feed cost = $120 / ton (unless given); deathloss cost = $75 / pig; and additional live weight = $45 / cwt.
