Evaluation of well-being, productivity, and longevity of pregnant sows housed in groups in pens with an electronic sow feeder or separately in gestation stalls     

Anil L  Anil SS  Deen J  Baidoo SK  Wheaton JE 《American journal of veterinary research》2005,66(9):1630-1638

OBJECTIVE: To compare well-being, performance, and longevity of gestating sows housed in stalls or in pens with an electronic sow feeder (ESF). ANIMALS: 382 pregnant sows of parities 1 through 6. PROCEDURE: Sows were housed in separate stalls (n = 176) or group pens (206) with an ESF. Well-being of sows was assessed at various time points in terms of injuries, salivary cortisol concentration, and behavior in a novel arena or to a novel object. Farrowing performance and longevity of sows were also assessed. RESULTS: Total injury scores (TIS) of sows in pens were significantly higher at initial introduction and mixing. In stall-housed sows, TIS was significantly higher during late gestation. The TIS and cortisol concentration were significantly lower in stall-housed sows, compared with values for sows in pens. As parity increased, the likelihood of higher median TIS decreased significantly in pen-housed sows and increased significantly in stall-housed sows. The TIS of sows in pens was negatively correlated with body weight and backfat thickness, whereas these correlations were positive in stall-housed sows. Farrowing performance and results for novel arena or objects did not differ. Proportion of sows removed was significantly higher for pens than for stalls; lameness was the major reason for removal for both systems. CONCLUSIONS AND CLINICAL RELEVANCE: Stalls impose space restrictions for larger sows, resulting in injuries during late gestation. Interventions are needed to minimize aggression during initial introduction and mixing and at the ESF in pens to reduce severe injuries or lameness of gestating sows.  相似文献   

Comparison of injuries in sows housed in gestation stalls versus group pens with electronic sow feeders     

Anil L  Bhend KM  Baidoo SK  Morrison R  Deen J 《Journal of the American Veterinary Medical Association》2003,223(9):1334-1338

OBJECTIVE: To compare the location and severity of injuries in pregnant sows housed in individual gestation stalls with that in pregnant sows housed in dynamic groups in pens with electronic sow feeders. DESIGN: Prospective study. ANIMALS: 100 pregnant sows of parity 1 to 3 and various body weights. PROCEDURE: Fifty sows each were randomly allotted to gestation stalls or group pens with electronic sow feeders. Injuries were scored on the basis of location, number, and depth of wounds. Injury scores for sows in both housing systems were compared during a period of 90 days. The influence of factors such as duration of stay in the housing system, parity, and body weight on sow injuries was also examined. RESULTS: Injury scores were higher in group pens with electronic sow feeders. As body weight increased, injury scores decreased for sows housed in group pens with electronic sow feeders and increased for sows housed in gestation stalls. There was a significant negative association between second parity and total injury scores. CONCLUSIONS AND CLINICAL RELEVANCE: Modifications in housing system design and management procedures are needed to reduce injuries in pregnant sows.  相似文献

Attenuated cytokine responses in porcine lymph node cells stimulated with CpG DNA are associated with low frequency of IFNalpha-producing cells and TLR9 mRNA expression   总被引：1，自引：0，他引：1  

Dar A  Nichani AK  Benjamin P  Lai K  Soita H  Krieg AM  Potter A  Babiuk LA  Mutwiri GK 《Veterinary immunology and immunopathology》2008,123(3-4):324-336

The immune stimulatory effects of synthetic CpG DNA, on porcine peripheral blood mononuclear cells (PBMC) have been reported, but little is known about CpG-induced responses in other lymphoid tissues of pigs. We investigated innate immune responses induced by CpG DNA in cells from blood, lymph nodes (LN) and spleens of pigs. Porcine PBMC and lymph node cells (LNC) were stimulated in vitro with three classes (A-, B- and C-class) of CpG oligodeoxynucleotides (ODNs), and a non-CpG control ODN. All three classes of CpG ODNs induced significant production of IFNalpha, TNFalpha, IL-1, IL-6 and IL-12 in PBMC. In contrast, in LNC, only IL-12 was stimulated by all three classes of CpG ODNs, while IFNalpha, and IL-6 were induced by A- and C-class ODNs. No TNFalpha was induced in LNC by any of the ODNs. Significant lymphocyte proliferation was induced in PBMC by all three classes of CpG ODNs and non-CpG control. However, in LNC, B- and C-class ODNs induced significant proliferation, while no proliferation was seen with A-class and non-CpG control ODN. All three classes of ODNs induced NK-like cytotoxicity in PBMC and spleen cells, but were less effective in inducing NK cytotoxicity in LNC. We then investigated the reasons for the relatively poor CpG-induced responses in LNC. Our investigations revealed that LNC had a lower frequency of IFNalpha-secreting cells and expressed low levels of TLR9 mRNA compared to PBMC. We conclude that the lower number of IFNalpha-secreting cells and receptor expression may contribute to the attenuated responses in LNC following stimulation with CpG ODN.  相似文献   

Rice Bran Oil: Emerging Trends in Extraction,Health Benefit,and Its Industrial Application     

Sneh Punia  Manoj Kumar  Anil Kumar Siroha  Sukhvinder Singh Purewal 《水稻科学》2021,28(3):217-232

Rice bran oil(RBO) is unique among edible vegetable oils because of its unique fatty acid composition, phenolic compound(γ-oryzanol, ferulic acid) and vitamin E(tocopherol and tocotrienol). It has become a great choice of cooking oil because of its very high burning point, neutral taste and delicate flavour. Non-conventional methods of RBO extraction are more efficient and environmentally friendly than conventional extraction methods. Advances in RBO extraction using innovative extraction strategies like super/sub-critical CO_2, microwave-assisted, subcritical H_2 O, enzyme-assisted aqueous and ultrasoundassisted aqueous extraction methods have proven to significantly improve the yields along with improved nutritional profile of RBO. The compositions and strategies for stabilization of RBO are well discussed. The constituents are present in the RBO contribute to antioxidative, anti-inflammatory, antimicrobial, antidiabetic and anti-cancerous properties to RBO. This has helped RBO to become an important substrate for the application in food(cooking oil, milk product and meat product) and non-food industries(polymer, lubricant, biofuel, structural lipid and cosmetic). This review provided comprehensive information on RBO extraction methods, oil stabilization, existing applications and health benefits.  相似文献   

Organic-acid-producing,phytate-mineralizing rhizobacteria and their effect on growth of pigeon pea (Cajanus cajan)     

Kuldeep J. Patel  Anil K. Singh  G. Nareshkumar  G. Archana 《Applied soil ecology》2010,44(3):252-261

Phytates represent a significant pool of organic phosphorus (Po) that is largely unavailable to plants. This study deals with phytate-mineralizing (PM), organic-acid-producing (OAP) rhizobacterial isolates, their characterization and their effect on plant growth. Their genetic diversity was assessed by 16S rRNA amplified ribosomal DNA restriction analysis (ARDRA) and selected isolates were identified by partial sequencing of 16S rRNA gene. Na-phytate and Po rich poultry farm manure (PFM) used as sources of phosphorus in semi-solid-agar (SSA) medium and soil respectively, for plant inoculation studies, where Cajanus cajan (pigeon pea) used as plant. Of thirty-nine rhizobacterial isolates, nineteen were proficient at releasing phosphate (Pi) (up to 85 μg/ml) from sparingly soluble calcium (Ca)-phytate and concomitantly decreasing the pH of minimal medium with 100 mM glucose from 8.0 to below 5. When the medium contained glycerol in place of glucose, Ca-phytate remained undissolved with no significant Pi released and no decline in pH. Genetic diversity of phytate-mineralizing (PM) rhizobacterial isolates suggests that the isolates mainly fall in two populations: acid-producing (AP) population (mainly represented by members of Enterobacteriaceae) and non-AP population. OAP-PM rhizobacterial isolates were identified as Citrobacter, Pantoea, Klebsiella and Enterobacter species. Organic acids (OAs) secreted by PM isolates were detected by HPLC, showed secretion of gluconic and acetic acids. Importance of OAs in Ca-phytate dephosphorylation was demonstrated in vitro using A. ficuum phytase. Gluconate and acetate additions enhanced phytase catalyzed dephosphorylation of Ca-phytate in vitro. Sonicated cell lysates of isolates showed significant Pi release from Ca-phytate compared to whole cells, indicating inaccessibility of Ca-phytate due to poor solubility. Selected isolates showed that they possess cell-associated acid phytase and modulators of phytase activity suggested that the enzymes are histidine acid phosphatase (HAP) type of phytase. OAP-PM isolates PP1 and DHRSS showed significant increase in dry shoot/root ratio and P content of shoot in Na-phytate containing semi-solid agar (SSA) medium, but isolate DHRSS did not increase dry shoot/root ratio in soil experiments containing poultry farm manure as source of P, although it significantly increased shoot P content of plants. The inoculation of isolates enhanced the shoot P content and dry shoot/root ratio, but did not increase the dry weight in SSA medium. It may be concluded that some OAP-PM rhizobacterial isolates that release P from Ca-phytate show increase in shoot P content in phytate containing SSA medium and in soils.  相似文献   

Alley coppice—a new system with ancient roots     

Christopher D. Morhart  Gerry C. Douglas  Christian Dupraz  Anil R. Graves  Michael Nahm  Pierluigi Paris  Udo H. Sauter  Jonathan Sheppard  Heinrich Spiecker 《Annals of Forest Science》2014,71(5):527-542

Context

Current production from natural forests will not satisfy future world demand for timber and fuel wood, and new land management options are required.

Aims

We explore an innovative production system that combines the production of short rotation coppice in wide alleys with the production of high-value trees on narrow strips of land; it is an alternative form of alley cropping which we propose to call ‘alley coppice’. The aim is to describe this alley coppice system and to illustrate its potential for producing two diverse products, namely high-value timber and energy wood on the same land unit.

Methods

Based on a comprehensive literature review, we compare the advantages and disadvantages of the alley coppice system and contrast the features with well-known existing or past systems of biomass and wood production.

Results

We describe and discuss the basic aspects of alley coppice, its design and dynamics, the processes of competition and facilitation, issues of ecology, and areas that are open for future research.

Conclusion

Based on existing knowledge, a solid foundation for the implementation of alley coppice on suitable land is presented, and the high potential of this system could be shown.  相似文献   

Expression of skin color genes in lymphocytes of Karan Fries cattle and seasonal relationship with tyrosinase and cortisol     

Uttarani Maibam  Sohan Vir Singh  Anil Kumar Singh  Suresh Kumar  Ramesh Chandra Upadhyay 《Tropical animal health and production》2014,46(7):1155-1160

To evaluate difference in the expression of skin color genes (melanocortin 1 receptor (MC1R) and premelanosome (PMEL)) in lymphocytes during winter and summer season and their correlation with tyrosinase enzyme and cortisol, ten Karan-Fries heifers were selected from National Dairy Research Institute (NDRI) cattle farm. Blood samples were collected from the animals during winter (THI?=?60) and summer (THI?=?83) season at weekly intervals. Relative MC1R and PMEL messenger RNA (mRNA) expression of Karan Fries cattle was found to be significantly (P?P?P?相似文献   

Indigenous sheep breeds of North Ethiopia: characterization of their phenotype and major production system     

Zelealem Tesfay Gebretsadik  Anil Kumar Anal 《Tropical animal health and production》2014,46(2):341-347

A study was conducted in Tigrai, Northern Ethiopia to describe the sheep breeds and their production system. The survey was done in selected districts known for their high sheep population density. The phenotype characterization identified distinct features for each breed. The breeds are Aberegelle, Ille, Begait, and the common Tigrai highland sheep. The strong discriminating phenotypes are face profile, tail type, and compactness; accounting for 83.48, 17.95, and 2.93 % respectively of the total variability among breeds. The flock structure are affected by the market demand; requirements of breeding females and feed availability. Farmers tend to keep more female sheep for longer (culling age of 5.9?±?0.4 and 1.9?±?0.5 for females and males, respectively) for the reasons of feed shortage and need to maximize number of breeding female. The ratio of male to overall female is large (1:6) and thus a single ram gets maximum contact time with ewes and ewe lambs. The overall average age at puberty for females is 9–14 months. However, the presence of very young lamb rams and uncontrolled mating system lead to early breeding of females which results in low conception rate, low birth weight, poor survival rates, and in extreme cases causing inbreeding. It was also possible to identify the critical control points such as breed, age of animals, nutrition, and feeding systems affecting the provision of live animals for good meat quality.  相似文献
