The replacement value of undecorticated sunflower meal (SFM) in the diets of dairy animals was assessed on-station and on-farm. Eighteen primiparous crossbred (Bos taurus×Bos indicus) cows (350.4±8.84 kg), randomly allocated to three groups, were used in the on-station study. The animals were fed on either a conventional concentrate supplement (control) or on an experimental concentrate, in which SFM replaced 25% (SFM-25) or 50% (SFM-50) of the CP in the control supplement. Green oats (Avena sativa) were supplied ad libitum. A metabolism trial conducted following 60 days of experimental feeding revealed that the intakes of DM, DCP and TDN were similar among the groups. The digestibilities of OM, CP, EE, NDF and ADF were also without significant differences. All the groups were in positive nitrogen balance. Inclusion of SFM at either level had no effect on the intake, excretion or retention of nitrogen. The daily milk yield and its composition did not differ among the dietary treatments. Moreover, the efficiency of utilization of DOM and TDN for FCM production tended to reflect, although non-significantly, increasing levels of SFM inclusion. In the on-farm study, seven multiparous milking buffaloes belonging to six farmers were used to assess the effect of replacing 20% of the CP of the conventional supplement with SFM, in a predominantly crop residue-based diet. The study continued for 4 months and revealed that the average daily feed intake and milk production was similar in the control and SFM-fed groups. It was concluded that SFM can be effectively utilized as a cheaper replacement for costly oil cakes and wheat bran for economic milk production by smallholder farmers. 相似文献

Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae) is an important pest in cucumber greenhouses in Çamönü (Menderes, Izmir), Turkey. In a study carried out in cucumber greenhouses during the spring and autumn seasons of 1999 and 2000, leaves were sampled weekly and kept in the laboratory to observe and count emerging leafminers and parasitoid adults. Five parasitoid species were collected: the braconidsBracon intercessor Nees von Esenbeck andOpius meracus Fischer, which occurred only in the spring; and the eulophidsDiglyphus crassinervis Erdös,Diglyphus isaea (Walker) andNeochrysocharis formosa (Westwood), which occurred in both the spring and autumn seasons.D. isaea andN. formosa were the predominant parasitoid species found.O. meracus was recorded for the first time as a Turkish species andB. intercessor was recorded for the first time inL. huidobrensis. 相似文献

Liriomyza cicerina (Rondani, 1875) (Diptera: Agromyzidae) is an important pest on chickpea (Cicer arietinum L.) in some regions of Turkey. The objective of this study was to determine whether the populations ofL. cicerina on different varieties of chickpea plants during the 2004 and 2005 production seasons affected yield in Sanliurfa province.
The trials were carried out using eight different varieties of chickpea with three replicates. During each season, larval
densities on leaves were assessed weekly. TheL. cicerina larval population was lowest on four varieties for both seasons. There were very minor differences in yield among the eight
varieties in the production seasons. There was no correlation found between larval density and yield loss.

Analysis of environmental samples obtained from the Live Poultry Markets (LPMs) of Dhaka City, Bangladesh, has revealed that the highest degree of prevalence of highly pathogenic avian influenza A (HPAI, H5N1), besides other subtypes of the LPAI virus, poses the plausible risk of transmission of these viruses between human and poultry species. The present study was conducted using the OIE risk analysis framework to assess the risk level of each pathway successively. The estimated risk parameters were integrated towards to obtain the overall risk level for each specific HPAI transmission pathway using the matrix adapted by Cristobel Zepeda accompanying other expert consultations. The relevant data obtained from published and unpublished sources, together with survey data of field observations, were used to formulate and confirm the risk pathways and their associated risks. The results revealed that the risk of the release of the HPAI virus was medium when exposure was high. Additionally, the consequence would be considered very high with a medium degree of uncertainty for all parameters. Ultimately, the overall risk for transmission was estimated as medium with a medium degree of uncertainty. The findings of this study reveal that there is a significant threat that HPAI virus transmission could occur among poultry and humans and effectively sustain within the environment of the LPMs. Our findings are primarily focused on public health considerations, the hygienic slaughter of poultry and the relevant cleaning and sanitation practices conducted in the LPMs to support evidence‐based decision‐making processes. The findings of the study have the potential to be used to formulate effective risk reduction measures and can be further adapted in low‐resource settings without major infrastructural changes required of the LPMs. All of which would reduce the risk of HPAI virus release and further lessen the degree of exposure and transmission in established LPMs. 相似文献

Accurate diagnosis of foetal sex in pregnant mare is helpful for many breeders, both for private or commercial purposes. In this study, in order to pre-natal foetal sexing in equine, we used TaqMan duplex real-time PCR to detect the specific regions of SRY and TSPY genes on extracted cell-free foetal DNA from maternal blood. Peripheral blood samples from 50 pregnant Arabian mares with singleton foetuses were collected. Cell-free foetal DNA was extracted from maternal plasma, and duplex real-time PCR assays were performed with TaqMan probes and primers. Amplification of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene was used as control of DNA extraction procedure. From the 50 sampled mares, 28 cases had female and 22 mares had male foetuses. The final results for 46 samples were conclusive, and from them, 43 cases were predicted correctly. Sensitivity, specificity and accuracy of the test were 90.48%, 96% and 93.48%, respectively. In conclusion, a TaqMan duplex real-time PCR was set up to pre-natal detection of foetal sex in equine. The method was fast and decreased the false-positive and false-negative results. The technique can be used as a routine procedure in farms by collecting only a blood sample. 相似文献

This study examined how inclusion of dried distillers' grains with solubles (DDGS) in finishing lamb diets for different periods affects some physiological indicators and meat quality. A total of 40 male lambs were divided into four groups according to feeding regimen during the 120-day finishing period as follows: C120: no DDGS included in diet for 120 days; D120: DDGS included in diet for 120 days; D75: no DDGS included in diet for 45 days + DDGS included in diet for 75 days; D45: no DDGS included in diet for 75 days + DDGS included in diet for 45 days. Dietary inclusion rate of DDGS was 27.5%. Fattening performance and rumen parameters were not affected by treatment. Feeding regimens had no significant effect on meat quality except the instrumental tenderness and juiciness score. DDGS fed lambs had higher level of total trans fatty acids and n-6/n-3 ratio in meat. 10t-C18:1, 11t-C18:1 and 9c,11t conjugated linoleic acid contents of adipose tissue were higher in all the DDGS groups compared with C120 lambs (p < .001). These results suggest that soybean meal can be replaced with corn DDGS in lamb diets for up to 120 days during the finishing period with no adverse effects on some physiological response feedlot performance and meat quality. 相似文献

Genetic diversity throughout the rapeseed (Brassica napus ssp. napus) primary gene pool was examined by obtaining detailed molecular genetic information at simple sequence repeat (SSR) loci
for a broad range of winter and spring oilseed, fodder and leaf rape gene bank accessions. The plant material investigated
was selected from a preliminary B. napus core collection developed from European gene bank material, and was intended to cover as broadly as possible the diversity
present in the species, excluding swedes (B. napus ssp. napobrassica (L.) Hanelt). A set of 96 genotypes was characterised using publicly available mapped SSR markers spread over the B. napus genome. Allelic information from 30 SSR primer combinations amplifying 220 alleles at 51 polymorphic loci provided unique
genetic fingerprints for all genotypes. UPGMA clustering enabled identification of four general groups with increasing genetic
diversity as follows (1) spring oilseed and fodder; (2) winter oilseed; (3) winter fodder; (4) vegetable genotypes. The most
extreme allelic variation was observed in a spring kale from the United Kingdom and a Japanese spring vegetable genotype,
and two winter rape accessions from Korea and Japan, respectively. Unexpectedly the next most distinct genotypes were two
old winter oilseed varieties from Germany and Ukraine, respectively. A number of other accessions were also found to be genetically
distinct from the other material of the same type. The molecular genetic information gained enables the identification of
untapped genetic variability for rapeseed breeding and is potentially interesting with respect to increasing heterosis in
oilseed rape hybrids. 相似文献
