Gaining a detailed knowledge on the impact of a feedstuff on pig growth and physiological responses is critical for its effective utilization. Thus, the purpose of this study was to investigate the effect of distillers dried grains with solubles derived from co‐fermentation of wheat and corn (wcDDGS) on performance, carcass and visceral organ weights, whole‐body O2 consumption and heat production (HP) in growing barrows. The experimental diets were as follows: corn–soybean meal diet (Control), Control + 15% wcDDGS and Control + 30% wcDDGS. In Exp. 1, 48 pair‐housed pigs of average BW 18.6 ± 1.5 kg (mean ± SD) were allotted to the 3 diets (n = 8). Pigs had free access to water and feed for a 28‐day period during which ADG and ADFI were calculated weekly. Thereafter, 1 pig/pen was killed to measure carcass and visceral organ weights. Overall, wcDDGS linearly decreased (p < 0.05) ADFI and ADG but had no effect on G:F (p > 0.10). The ADFI was 1.55, 1.45 and 1.36 kg/day for diets containing 0, 15 and 30% wcDDGS respectively; corresponding values for ADG were 0.79, 0.75 and 0.67 kg/day respectively. A linear decline (p = 0.01) in eviscerated hot carcass weight was observed as dietary wcDDGS increased. In Exp. 2, 18 pigs of average BW 20.4 ± 2.4 kg (mean ± SD) were individually housed in metabolism crates and fed the 3 diets (n = 6) at 550 kcal ME kg BW?0.60day for a 16‐day period followed by measurement of O2 consumption using an indirect calorimeter. Diet had no effect (p > 0.10) on whole‐body O2 consumption and HP. In conclusion, increasing wcDDGS content in growing pig diets linearly reduced ADFI, ADG and eviscerated hot carcass weight but had no effect on G:F, visceral organ weights or HP. 相似文献

Diarrhoeic faecal samples from 210 humans and 192 swine were screened for Yersinia enterocolitica in 1990. Ten and 8 Y. enterocolitica strains were isolated from pig and man, respectively. The isolates were found to belong to Wauter's biotypes 1, 2, 3 and 4. Biotype 2 was isolated mainly from human stool samples. Biotype 3 was found only in swine while biotypes 1 and 4 were isolated from both man and swine. All the 18 strains showed varying degrees of sensitivity to antibiotics used in this investigation. The organisms were consistent in their resistance to ampicillin and penicillin. 相似文献

The mortality losses of pigs of various age groups affected by the 2001 African swine fever outbreak in Ibadan Nigeria were
analyzed and evaluated. Thirty one thousand nine hundred and sixteen (31,916) pigs on three hundred and six (306) farms reported
by the Pig Farmers Association of Nigeria and the State Ministry of Agriculture and Natural Resources were involved. Gross
mortality was ninety one percent (91%), while age group mortality ranged from 75.9% (growers), 83.1% (weaners), 91.2% (finishers)
and 99.8% (piglets); to 100.0% in gilts, sow and boars. Losses were estimated to worth nine hundred and forty one thousand,
four hundred and ninety one dollars, sixty seven cents (US $941,491.67). Highest financial loss was from sows (29.5% of total
loss), followed by gilts (16.6%), finishers (15.2%), weaners (10.7%), boars (10.6%), growers (10.6%) and piglets (8.2%). Average
mortality loss per farm of $3076.77 was of great financial and socioeconomic consequences for a developing country like Nigeria
with a low Gross Domestic Product figures. In conclusion, the need to immediately revisit and take recommended actions on
the 1998 Report of the FAO Consultancy Mission to Nigeria on Control and Eradication of an Outbreak of African swine fever
in Western Nigeria is stressed. 相似文献

An outbreak of swine pox on a pig farm in Ibadan, Nigeria is reported. Diagnosis was based on clinical and pathological signs and the observation of poxvirus particles in a serum sample. Neonatal deaths were common in the outbreak. Indigenous pigs did not show any sign of the disease even though mixed breeds were kept in the same pens. It is suggested that indigenous pigs were probably carriers of the swine pox virus. 相似文献

The influence of genotype and stocking densities on growth performance, carcass qualities, and cost-benefits of broilers were
examined in a 28-day trial. Two hundred and seven 4-week-old birds each of Anak Titan and Arbor Acre hybrid broiler types
were randomly assigned to three stocking density treatments of 8.3, 11.1, and 14.3 birds/m2 in a 2 × 3 factorial arrangement. Final body weight, average weekly body weight and average weekly feed intake were affected
(P < 0.05) by strain, with higher means recorded for Arbor Acres. However, average weekly body weight gain and feed conversion
ratio were similar (P > 0.05) in both genetic groups. The effect of placement density on some growth parameters did not follow a linear trend.
Arbor Acres had significantly (P < 0.05) higher relative (%) fasted body, carcass, back, neck, and wing weights compared to Anak Titans. Housing density effect
(P < 0.05) was observed for relative (%) fasted body, shank, and wing weights of birds. However, the relative weights of visceral
organs of birds were not significantly (P > 0.05) influenced by genotype and housing density. The economic analysis revealed that higher gross margin was recorded
for Arbor Acres compared to Anak Titans (€2.76 versus €2.19; P < 0.05, respectively). Conversely, stocking rate did not exert any influence (P > 0.05) on profit margin. Genotype × stocking density interaction effect was significant for some of the carcass indices
investigated. It is concluded that under sub-humid conditions of a tropical environment, the use of Arbor Acre genetic type
as well as a placement density of 14.3 birds/m2 appeared to be more profitable. 相似文献
