本试验旨在探讨葡萄糖氧化酶(GOD)对大河乌猪妊娠母猪繁殖性能、血清抗氧化指标和饲粮养分消化率的影响。选择健康经产(3~5胎)大河乌猪妊娠母猪60头,随机分为4个组,每组15个重复,每个重复1头猪。对照组饲喂基础饲粮,GOD1、GOD2和GOD3组饲喂在基础饲粮中分别添加200、400和600 mg/kg GOD的试验饲粮。母猪产前30 d开始试验,直到仔猪断奶时结束。结果表明:1)与对照组相比,饲粮中添加400和600 mg/kg GOD可增加大河乌猪妊娠母猪的产仔数和产活仔数(P0.05);饲粮中添加600 mg/kg GOD可显著增加仔猪初生重和20日龄重(P0.05)。2)与对照组相比,饲粮中添加600 mg/kg GOD可显著增加大河乌猪妊娠母猪和仔猪血清谷胱甘肽过氧化物酶(GSH-Px)活性和总抗氧化能力(T-AOC)(P0.05),显著降低血清丙二醛(MDA)含量(P0.05)。3)与对照组相比,饲粮中添加600 mg/kg GOD可显著增加大河乌猪妊娠母猪饲粮粗脂肪(EE)和磷(P)的消化率(P0.05)。本试验条件下,大河乌猪母猪妊娠后期(产前30 d)饲粮中添加600 mg/kg GOD可提高母猪的繁殖性能,增强母猪和仔猪抗氧化能力,提高母猪对饲粮EE和P的消化能力,提高饲粮利用率。 相似文献

复合益生菌制剂对繁殖母猪生产性能的影响 总被引：1，自引：0，他引：1
为了研究不同添加水平的复合益生菌制剂对繁殖母猪生产性能的影响。试验选用胎次(6-9)、体况、背膘等差异不显著的二元杂母猪24头(P0.05),随机分成1个对照组和3个试验组,共4组,每组3个重复,每个重复2头母猪。对照组饲喂基础日粮,试验组第1、2、3组分别在基础日粮基础上添加0.05、0.10和0.15 mg/kg的复合益生菌制剂。第1阶段饲粮是从妊娠75 d喂至妊娠90 d,第2阶段饲粮是从妊娠91 d喂至妊娠114 d再到哺乳21 d断奶,测定母猪繁殖性能、仔猪生长性能以及仔猪免疫球蛋白指标。结果表明母猪繁殖性能以添加0.15 mg/kg复合益生菌组的初生质量最高但与对照组差异不显著(P0.05),显著高于0.05 mg/kg组(P0.05);初生窝质量同上。健仔率0.10 mg/kg、0.15 mg/kg组显著高于对照组和0.05 mg/kg组(P0.05),较对照组分别高出8%、7%。仔猪断奶成活率差异不显著(P0.05);平均断奶窝质量:0.10 mg/kg、0.15 mg/kg分别显著高于0.05 mg/kg组(P0.05),相比对照组分别提高了4.98%和5.45%,但差异不显著(P0.05)。免疫球蛋白各试验组指标均高于对照组,其中IgG、IgA显著高于对照组(P0.05),以添加0.15 mg/kg复合益生菌组最高。所以添加0.15%的复合益生菌制剂对提高繁殖母猪的生产性能的效果最佳。建议繁殖母猪基础日粮中以添加0.15 mg/kg的复合益生菌制剂为宜。 相似文献

Influence of different phosphorus levels and phytase supplementation in gestation diets on sow performance 总被引：1，自引：0，他引：1
Lyberg K Andersson HK Simonsson A Lindberg JE 《Journal of animal physiology and animal nutrition》2007,91(7-8):304-311
A total of 104 sows of different parities were studied. They were fed four diets with different phosphorus (P) levels during gestation for two reproductive cycles, while the same diet was fed during lactation. The aim was to decrease the total P level in the diet during gestation and to evaluate the effect on sow performance. The gestation treatments were low P (LP-; 3.7 g P/kg feed), low P with phytase (LP+, Ronozyme P; 765 FTU/kg feed), medium P (MP; 4.5 g P/kg feed) and high P (HP; 6.0 g P/kg feed). Daily feed allowances were 2.6 kg during gestation and 9.2 kg during lactation. Number of born piglets and piglet mortality were higher (p < 0.05) in the LP treatments than in the MP and HP treatments. No difference (p > 0.05) in the numbers of live-born piglets, piglet birthweights, sow weights or piglet weight gains was found between the treatments. Phosphorus level in sow milk was the highest (p < 0.05) in the MP treatment, while no effects (p > 0.05) of treatment were found on milk Ca levels, P and Ca levels in serum of sows and piglets, nor on the analysed mineral, fat and protein contents of piglets. The estimated average requirement of P for the entire gestation period was 4.4-4.5 g/day. In conclusion, a reduction of dietary total P content during gestation did not result in negative effects on sow or piglet performance. This suggests that it should be possible to lower the dietary P content for gestating sows, compared with earlier recommendations, and thereby reduce the environmental P pollution. 相似文献

试验旨在研究妊娠后期和哺乳期母猪饲粮中添加植物小肽对1~2胎二元杂种母猪繁殖性能以及初生仔猪活力的影响。采用单因素试验设计,选取40头妊娠90 d的二元杂种母猪(杜洛克伊大白,1~2胎),按随机区组法分为2个处理,每个处理20个重复,每个重复1头母猪。对照组饲喂商品哺乳母猪饲粮(含2%鱼粉),植物小肽组饲喂2%植物小肽(替代1%豆粕和1%鱼粉)。试验期共45 d(从妊娠90 d至21 d断奶)。试验结果表明,两个处理组母猪繁殖性能差异不显著(P>0.05),但与对照组相比,植物小肽组弱仔减少了0.55头(P>0.05),木乃伊胎提高了0.20头(P=0.080)。植物小肽组仔猪初生窝重增加了1.26 kg(P>0.05),初生个体重增加了0.13 kg(P=0.077)。植物小肽组哺乳仔猪死淘率和腹泻率分别比对照组低31.01%和64.14%。两个处理组初生仔猪活力无显著差异(P>0.05)。综上所述,在本试验条件下,1~2胎母猪妊娠后期和哺乳期饲粮中添加2%植物小肽替代部分鱼粉和豆粕不影响母猪繁殖性能,还能一定程度增加仔猪初生重,对仔猪活力无影响。 相似文献

This study evaluated the effects of different gestation housing types on reproductive performance of sows. A total of 60 sows (218 ± 24 kg body weight) with mixed parity were used. During gestation, 28 sows were housed in groups with electronic sow feeders (space allowance = 1.26 m2/sow) and 32 sows were housed in individual stalls (space allowance = 1.20 m2/sow). Sows from both housing types were moved to farrowing crates on day 109 of gestation and stayed until weaning (18 days post‐farrowing). Typical corn‐soybean meal diets were provided to sows during gestation and lactation. Measurements were reproductive performance of sows at farrowing as well as performance of sows and their litter during lactation. Similar total numbers of piglets born at farrowing were observed for sows gestated in both housing types. However, group‐housed gestation sows had more mummies (0.321 vs. 0.064; P < 0.05) and stillbirths (0.893 vs. 0.469; P = 0.073) at farrowing than individual‐housed gestation sows. Consequently, individual‐housing type had higher percentage of piglets born alive (95.5 vs. 90.4%; P < 0.05) than the group‐housing type. Therefore, improved reproductive performance of sows from individual gestating housing was confirmed in this study. 相似文献

Effects of dextrose plus lactose in sow’s feed were tested on subsequent reproductive performance and within litter birth weight variation. During the last week of gestation and lactation, sows were either fed a commercial lactation diet (Control: C), or an isocaloric diet containing 25 g/kg dextrose plus 25 g/kg lactose (Treatment: T). In the subsequent weaning‐to‐oestrus interval (WEI), all sows received the same amount of a commercial feed, but T sows were supplemented with 150 g dextrose plus 150 g lactose per day. Weight and backfat changes were recorded as well as litter characteristics during the treatment period and the subsequent parity. No significant effect of treatment was found on the subsequent reproductive performance, including the number of piglets born, although the number of live born piglets was 0.51 larger (p = 0.31) and weight of the live born piglets was 84 g higher in the T sows (p = 0.07) than in the C sows. When sows were categorized in sows with 12 or less and more than 12 total born piglets in the previous litter, treatment of sows with dextrose plus lactose resulted for the group with 12 or less piglets in a strong increase in subsequent total born piglets (13.97), whereas in the untreated sows the subsequent litter size was 11.89. In the group with more than 12 total born piglets, no effect of treatment was found (interaction between previous litter size and treatment p = 0.03). The within litter variation in birth weight in the subsequent litter was numerically lower in the T sows. We concluded that the use of dextrose and lactose during lactation and WEI seems to enhance litter size in sows with low previous litter size and seems to have the potential to reduce the within litter variation in birth weight. 相似文献

A regional experiment was conducted at 8 experiment stations, with a total of 320 sows initially, to evaluate the efficacy of adding 13.35% ground wheat straw to a corn-soybean meal gestation diet for 3 successive gestation-lactation (reproductive) cycles compared with sows fed a control diet without straw. A total of 708 litters were farrowed over 3 reproductive cycles. The basal gestation diet intake averaged 1.95 kg daily for both treatments, plus 0.30 kg of straw daily for sows fed the diet containing ground wheat straw (total intake of 2.25 kg/d). During lactation, all sows on both gestation treatments were fed ad libitum the standard lactation diet used at each station. Response criteria were sow farrowing and rebreeding percentages, culling factors and culling rate, weaning-to-estrus interval, sow BW and backfat measurements at several time points, and litter size and total litter weight at birth and weaning. Averaged over 3 reproductive cycles, sows fed the diet containing wheat straw farrowed and weaned 0.51 more pigs per litter (P 相似文献

This experiment was conducted to investigate the effects of inulin supplementation in low‐ or high‐fat diets on both the reproductive performance of sow and the antioxidant defence capacity in sows and offspring. Sixty Landrace × Yorkshire sows were randomly allocated to four treatments with low‐fat diet (L), low‐fat diet containing 1.5% inulin (LI), high‐fat diet (H) and high‐fat diet containing 1.5% inulin (HI). Inulin‐rich diets lowered the within‐litter birth weight coefficient of variation (CV, p = 0.05) of piglets, increased the proportion of piglets weighing 1.0–1.5 kg at farrowing (p < 0.01), reduced the loss of body weight (BW) and backfat thickness (BF) during lactation (p < 0.05) and decreased the duration of farrowing as well as improved sow constipation (p < 0.05). Sows fed fat‐rich diets gained more BW during gestation (p < 0.01), farrowed a greater number of total (+1.65 pigs, p < 0.05) and alive (+1.52 pigs p < 0.05) piglets and had a heavier (+2.06 kg, p < 0.05) litter weight at birth as well as a decreased weaning‐to‐oestrous interval (WEI, p < 0.01) compared with sows fed low‐fat diets. However, it is worth noting that the H diet significantly decreased the serum activities of superoxide dismutase (T‐SOD) and glutathione peroxidase (GSH‐Px) and increased the serum malondialdehyde (MDA) levels in sows and piglets (p < 0.05). In contrast, HI diet enhanced the activities of T‐SOD and GSH‐Px and decreased the serum MDA concentrations (p < 0.05) in sows and piglets. In summary, the fat‐rich diets fed to sows during gestation had beneficial effects on reproductive performance, but aggravated the oxidative stress in sow and piglets. Inulin‐rich diets fed to sow during gestation had beneficial effects on within‐litter uniformity of piglet birthweight and enhanced the antioxidant defence capacity of sows and piglets. 相似文献
