    在资源受限的设置中,孕妇和哺乳期妇女和女孩(PBW/G)特别容易营养不良。可提供微量营养素强化的平衡能量蛋白(BEP)补充剂以提高母体营养状况并改善出生和婴儿结局。我们对已发表的文献进行了范围审查,以确定提供强化食品或现金以及至少3种微量营养素的BEP和其他相关营养干预措施对产妇的影响。出生,低收入和中等收入国家的婴儿/儿童结局。我们使用预定义的关键字和受控的词汇搜索词进行了PubMed搜索。所有标题和摘要均由两名独立审稿人审查是否符合资格,并根据结局类型提取数据。我们确定了149篇合格的研究文章,报告了总共21项试验和/或计划评估,这些试验和/或计划评估了一种或多种产品(强化的基于脂质的营养补充剂[LNS,n=12],强化混合粉[n=5],乳饮料[n=2],和当地食品/零食[n=3])提供118-750千卡/天和不同水平的蛋白质和微量营养素。这些方案评估中只有一项评估了提供现金和强化食品的影响。对产妇结局的影响,如妊娠体重增加和妊娠持续时间是有希望的,但不一致。15项研究报告了出生结果,对出生体重和出生身长的影响总体上是积极的。在15项研究中,有7项研究显示了对婴儿和儿童生长的持续益处,这些研究报告了这些结果中的至少一项。尽管数据稀疏。需要额外的研究来调查剂量问题,成本效益,并纳入多组分干预措施。
    In resource-constrained settings, pregnant and breastfeeding women and girls (PBW/G) are particularly vulnerable to undernutrition. Micronutrient-fortified balanced energy protein (BEP) supplementation may be provided to boost maternal nutritional status and improve birth and infant outcomes. We conducted a scoping review of the published literature to determine the impact of BEP and other related nutrition interventions that provided fortified food or cash along with a minimum of 3 micronutrients on maternal, birth, and infant/child outcomes in low- and middle-income countries. We conducted a PubMed search using pre-defined keywords and controlled vocabulary search terms. All titles and abstracts were reviewed for eligibility by two independent reviewers, and data were extracted according to outcome type. We identified 149 eligible research articles that reported on a total of 21 trials and/or programme evaluations which assessed the health impact of one or more products (fortified lipid-based nutrient supplement [LNS, n = 12], fortified blended flours [n = 5], milk-based beverages [n = 2], and local food/snacks [n = 3]) that provided 118-750 kcal/day and varying levels of protein and micronutrients. Only one of these programme evaluations assessed the impact of the provision of cash and fortified food. Effects on maternal outcomes such as gestational weight gain and duration of gestation were promising but inconsistent. Birth outcomes were reported in 15 studies, and the effects on birthweight and birth length were generally positive. Seven studies demonstrated sustained benefits on infant and child growth out of the 15 studies that reported at least one of these outcomes, although data were sparse. Additional research is needed to investigate issues of dose, cost-effectiveness, and incorporation into multi-component interventions.

    该研究旨在通过分析来自59个父亲和227个水坝的445只动物的数据来评估Hardhenu牛的表现特征。研究的重点是估算奶牛繁殖和生产性状的(协)方差成分和遗传参数。最小二乘法分析的结果表明产仔期(POC)对关键生产性状有显著影响(p<.01),包括第一次泌乳产奶量(FLMY),300天牛奶产量(FLMY300),研究人群的第一峰产奶量(FPY)和总泌乳产奶量(TLMY)。这些性状的最小二乘平均值报告如下:FLMY(2665.68±45.66kg),FLMY300(2425.52±34.41kg),FLL(312.95±3.83天),Hardhenu牛的FPY(11.52±0.15kg)和TLMY(9282.44±167.03kg)。在被研究的人群中,发现仅存在加性遗传变异性,并且对资源种群中的目标性状没有任何显着的母体效应。FLMY的直接遗传力估计(h2),FLMY300,FLL,FPY,Hardhenu牛的TLMY和其他性状范围为0.03至0.41。这些发现为影响性能特征的遗传因素提供了有价值的见解,有助于加强Hardhenu牛的育种和管理实践。
    The study aimed to assess performance traits in Hardhenu cattle by analysing data from 445 animals born to 59 sires and 227 dams. The investigation focused on estimating (co)variance components and genetic parameters for reproduction and production traits in dairy cattle. Results from least-squares analysis indicated a significant effect (p < .01) of the period of calving (POC) on key production traits, including first lactation milk yield (FLMY), 300-day milk yield (FLMY300), first peak yield (FPY) and total lactation milk yield (TLMY) in studied population. The least squares means for these traits were reported as follows: FLMY (2665.68 ± 45.66 kg), FLMY300 (2425.52 ± 34.41 kg), FLL (312.95 ± 3.83 days), FPY (11.52 ± 0.15 kg) and TLMY (9282.44 ± 167.03 kg) in Hardhenu cattle. In the studied population, only additive genetic variability was found to be present and there was absence of any significant maternal effect with respect to targeted traits in the resource population. Direct heritability estimates (h2) for FLMY, FLMY300, FLL, FPY, TLMY and other traits ranged from 0.03 to 0.41 in Hardhenu cattle. These findings offer valuable insights into the genetic factors influencing performance traits, contributing to the enhancement of breeding and management practices in Hardhenu cattle.

    目的是评估单独提供饲料原料(SF)和浓缩物喂养频率与提供TMR的影响,关于泌乳性能,瘤胃发酵,肠道CH4排放,营养素消化率,N使用效率,牛奶脂肪酸简介,和泌乳中期奶牛的血液变量。在研究开始时,将24头荷斯坦奶牛(12头初生和12个多胎)平均(±SD)141±35DIM和43±6kg/d的产奶量(MY)用于重复的3×3拉丁方设计实验,每个实验3个周期28d,由7天组成,用于适应饮食,11d用于估计净能量和可代谢蛋白质需求,10d用于数据和样本收集。奶牛根据奇偶校验进行分组,DIM,和我成4个拉丁方块。治疗分配平衡了遗留效应,将正方形内的奶牛分配到(1)随意饲喂TMR的基础日粮;(2)以SF饲喂随意饲喂的牧草和以3×/d(SF×3)喂养的浓缩物;(3)以SF饲喂的基础日粮,以随意饲喂的牧草和以6×/d(SF×6)饲喂的浓缩物。与TMR相比,SF使总QI降低1.2kg/d。治疗没有影响我的,牛奶成分,或ECM产量,与TMR相比,除了牛奶脂肪浓度降低和牛奶尿素N增加SF×3外。在SF中,饲料效率(MY/DMIkg)提高了7%,与TMR相比。乙酸盐的瘤胃摩尔比例和乙酸盐与丙酸盐的比例降低,与TMR和SF×6相比,SF×3增加了丙酸的摩尔比例。SF的每日CH4产量下降了9%,与TMR相比。在本研究中,肠溶CH4产量(每千克的DMI)不受处理的影响。在SF中,每公斤MY的甲烷强度倾向于降低10%,与TMR相比。奇数和支链的总和,奇数链,和安替苏牛奶脂肪酸倾向于或被SF增加,与TMR相比。营养素的摄入量倾向于或被SF减少,与TMR相比。在SF中,淀粉酶处理的NDF的消化率趋于降低,ADF的消化率降低了3%,与TMR相比。尿液和粪便N排泄物不受治疗影响。占总氮摄入量的百分比,单独提供饲料原料增加了牛奶N的分泌,表明SF提高了N的使用效率,与TMR相比。相对于TMR,SF降低了血液总脂肪酸浓度。与TMR和SF×6相比,SF×3增加了血尿素氮浓度。总的来说,通过单独提供饲料原料,提高了饲料和氮素的利用效率,并且增加浓缩物饲喂的频率可促进与通过饲喂TMR获得的效果相似的瘤胃发酵效果。
    The objective was to evaluate the effects of separate offering of feed ingredients (SF) and frequency of concentrate feeding versus offering a TMR, on lactational performance, ruminal fermentation, enteric CH4 emissions, nutrient digestibility, N use efficiency, milk fatty acid profile, and blood variables in mid-lactation dairy cows. Twenty-four Holstein cows (12 primi- and 12 multiparous) averaging (±SD) 141 ± 35 DIM and 43 ± 6 kg/d of milk yield (MY) at the beginning of the study were used in a replicated 3 × 3 Latin square design experiment with 3 periods of 28 d each, composed of 7 d for adaptation to the diets, 11 d for estimation of net energy and metabolizable protein requirements, and 10 d for data and samples collection. Cows were grouped based on parity, DIM, and MY into 4 Latin squares. Treatment allocation was balanced for carryover effects, and cows within square were assigned to (1) basal diet fed ad libitum as TMR; (2) basal diet fed as SF with forages fed ad libitum and concentrates fed 3×/d (SF×3); or (3) basal diet fed as SF with forages fed ad libitum and concentrates fed 6×/d (SF×6). Compared with TMR, SF decreased total DMI by 1.2 kg/d. Treatments did not affect MY, milk components, or ECM yield, except for a decrease in milk fat concentration and an increase in milk urea N by SF×3, compared with TMR. Feed efficiency (kg of MY/kg of DMI) was increased by 7% in SF, compared with TMR. Ruminal molar proportion of acetate and acetate-to-propionate ratio were decreased, whereas molar proportion of propionate was increased by SF×3, compared with TMR and SF×6. There was a 9% decrease in daily CH4 production by SF, compared with TMR. Enteric CH4 yield (per kg of DMI) was not affected by treatments in the current study. Methane intensity per kilogram of MY tended to be decreased by 10% in SF, compared with TMR. The sums of odd- and branched-chain, odd-chain, and anteiso milk fatty acids tended to be or were increased by SF, compared with TMR. Intake of nutrients tended to be or were decreased by SF, compared with TMR. The digestibility of amylase-treated NDF tended to be decreased and ADF digestibility was decreased by 3% in SF, compared with TMR. Urinary and fecal N excretions were not affected by treatments. As a percentage of total N intake, separate offering of feed ingredients increased milk N secretion, indicating an increased N use efficiency by SF, compared with TMR. Blood total fatty acid concentration was decreased by SF relative to TMR. Compared with both TMR and SF×6, SF×3 increased blood urea N concentration. Overall, feed and N use efficiencies were increased by separate offering of feed ingredients, and increasing the frequency of concentrate feeding promoted ruminal fermentation effects similar to those obtained by feeding a TMR.

    这项研究调查了饲喂淀粉酶启用的玉米青贮(ACS)对泌乳奶牛的性能和肠道气体排放的影响。在2周的协变量周期之后,在10周的随机完整区组设计实验中,将48只哺乳期中期的荷斯坦奶牛分配到3种处理中的1种。处理是含有相同比例的玉米青贮饲料(饮食DM的40%)的饮食如下:(1)常规杂交玉米青贮饲料对照(CON),(2)ACS取代控制青贮饲料(ADR),和(3)ADR日粮用磨碎的玉米粒代替大豆壳,以达到与CON(ASR)相同的日粮淀粉浓度。对照玉米青贮饲料和ACS在同一天收获,并含有40.3%和37.1%DM和(DM的%):37.2%和41.0%NDF以及37.1%和30.0%淀粉,分别。使用GreenFeed系统测量肠内气体排放。在协变量期间,由于与健康相关的问题,两头母牛被淘汰。使用口胃瘤胃取样技术从24头母牛(每个处理8头)收集瘤胃液。与CON相比,饲喂ADR的奶牛在第3、4和9周的实验期间增加了DMI,但处理不影响牛奶或ECM牛奶产量(平均39.0kg/d;SEM=0.89).与CON相比,饲料效率(每单位牛奶,但不是ECM)的ADR倾向于较低,而ASR的牛奶真蛋白浓度(趋势)和产量较低。相对于CON,ADR和ASR饮食均降低了牛奶尿素N。与CON相比,ADR增加了每日CH4排放量和排放强度,而ASR不增加。与对照玉米青贮相比,用ACS配制的两种饮食都倾向于增加原生动物总数。ASR的饮食NDF的总道消化率更高,ADR和ASR的ADF比CON更大。ADR增加了乙酸盐的摩尔比例(趋势)和乙酸盐与丙酸盐的比例,但不是ASR,与CON相比。在实验的最初几周,用ACS(具有较低的淀粉浓度)在奶牛的日粮中替换CON会增加STI。维护的ECM,倾向于降低饲料效率,增加了肠道CH4的排放,可能是由于易消化纤维的摄入量增加,与CON相比。
    This study investigated the effects of feeding an amylase-enabled corn silage (ACS) on the performance and enteric gas emissions in lactating dairy cows. Following a 2-wk covariate period, 48 mid-lactation Holstein cows were assigned to 1 of 3 treatments in a 10-wk randomized complete block design experiment. Treatments were diets containing the same proportion of corn silage (40% of dietary DM) as follows: (1) a conventional hybrid corn silage control (CON), (2) ACS replacing the control silage (ADR), and (3) the ADR diet replacing soybean hulls with ground corn grain to achieve the same dietary starch concentration as CON (ASR). Control corn silage and ACS were harvested on the same day and contained 40.3% and 37.1% DM and (% of DM): 37.2% and 41.0% NDF and 37.1% and 30.0% starch, respectively. Enteric gas emissions were measured using the GreenFeed system. Two cows were culled due to health-related issues during the covariate period. Ruminal fluid was collected from 24 cows (8 per treatment) using the orogastric ruminal sampling technique. When compared with CON, cows fed ADR had increased DMI during experimental wk 3, 4, and 9, but treatment did not affect milk or ECM milk yields (39.0 kg/d on average; SEM = 0.89). Compared with CON, feed efficiency (per unit of milk, but not ECM) tended to be lower for ADR, whereas milk true protein concentration (a tendency) and yield were lower for ASR. Milk urea N was decreased by both ADR and ASR diets relative to CON. Compared with CON, daily CH4 emission and emission intensity were increased by ADR but not ASR. Total protozoal count tended to be increased by both diets formulated with ACS when compared with control corn silage. Total-tract digestibility of dietary NDF was greater for ASR, and that of ADF was greater for both ADR and ASR versus CON. The molar proportion of acetate (a tendency) and acetate-to-propionate ratio were increased by ADR, but not ASR, when compared with CON. Replacement of CON with ACS (having lower starch concentration) in the diet of dairy cows increased DMI during the initial weeks of the experiment, maintained ECM, tended to decrease feed efficiency, and increased enteric CH4 emissions, likely due to increased intake of digestible fiber, compared with CON.

    目的:牛奶体细胞(SCC)数量之间的相关性,微生物的数量,并在五个具有相同品种奶牛的农场(F1-F5)上研究了牛奶的基本成分含量,但是有不同的挤奶系统。
    方法:从每个农场,在2022年3月至2023年2月期间,每月收集50份荷斯坦Friesien牛奶样品(250份样品/月;n=3,000)。来自农场F1和F5的样品进行了脂肪测试,蛋白质,乳糖,无脂肪干物质含量(FTIR光谱),对于SCC(Fossartical7),和差分电池(VetscanDC-Q)。
    结果:在使用自动挤奶系统(AMS)的农场F5(3.85±1.70%)和F4(3.82±0.21%)上确认了最高的脂肪含量。然而,从蛋白质含量的角度来看,这些农场的数值略低(<0.05)。F1未达到斯洛伐克立法规定的最低脂肪含量(2.84±0.81%)。比较表明,健康细胞和乳腺炎细胞之间的细胞大小没有太大差异。健康细胞的平均大小为约8.77±0.49μm。在监测期间,在牛奶样品中测定的平均值为292,000/mL(5.46±0.72log10SCC),而在今年剩下的时间里,数值保持在256,000/mL(5.40±0.80log10SCC).F1被归类为具有高TLC(总乳白细胞计数)浓度(5.58log10细胞/mL,406.65±53.80×103个细胞/mL)和主要的NEU分数(61%)。农场F2、F4和F5被分类为阴性农场(TLC为4.70±0.26log10细胞/ml)。
    结论:根据结果,健康牛奶中SCC的大小与乳腺炎牛奶中的SCC没有差异.从结果来看,可以得出结论,向最新一代机器人挤奶方法的过渡可以积极影响牛奶的产量和质量。
    OBJECTIVE: Correlations between the number of milk somatic cells (SCC), the number of microorganisms, and the content of basic components of milk were studied on five farms (F1-F5) with cows of the same breed, but with different milking systems.
    METHODS: From each farm, 50 Holstein Friesien milk samples were collected once a month (250 samples/month; n=3,000) during March 2022 - February 2023. Samples from farms F1 and F5 were tested for fat, protein, lactose, no fat dry matter content (FTIR spectroscopy), for the SCC (Fossomatic 7), and for the differential cells (Vetscan DC-Q).
    RESULTS: The highest fat content was confirmed on farm F5 (3.85 ± 1.70%) and F4 (3.82 ± 0.21%) with automatic milking system (AMS). However, from the point of view of protein content, these farms showed slightly lower values (<0.05). F1 did not meet the minimum required amount for fat content (2.84 ± 0.81%) set by the legislation of the Slovakia. The comparison shows that there is not much difference in cell size between healthy cells and mastitis cells. The average size of healthy cells was approximately 8.77 ± 0.49 μm. In the monitored period, the average values determined were at the level of 292,000/mL (5.46 ± 0.72 log10 SCC) in cow milk samples, while for the rest of the year, the values remained at 256,000/mL (5.40 ± 0.80 log10 SCC). F1 was categorized as a positive farm with a high TLC (total milk leucocyte count) concentration (5.58 log10 cells/mL, 406.65 ± 53.80 × 103 cells/mL) and a predominant NEU fraction (61%). Farms F2, F4, and F5 were classified as negative farms (TLC was 4.70 ± 0.26 log10 cells/ml).
    CONCLUSIONS: According to the results, the size of SCCs in healthy milk does not differ from SCCs found in mastitis milk. From the results, it can be concluded that the transition to the latest generation of robotic milking method can positively affect milk production and its quality.

    全球三分之一的人口是贫血的受害者,显着影响母婴健康,并与认知不良有关,生产力,和死亡风险。我们使用了从全国代表性调查中随机选择的4040名哺乳期母亲的记录。描述性统计数据进行了加权,并且使用标准血红蛋白截止点(低于12g/dl)。采用考虑与贫血相关的个体和社区水平因素的双变量和多变量多水平二元逻辑回归模型。报告了95%置信区间的粗比值比和调整后比值比。在埃塞俄比亚,32.3%(95%CI30.9-33.7%)的哺乳期妇女贫血,23.4%的人患有轻度疾病,7.3%适度,和1.2%的严重贫血。牧区(远方,索马里,和奥罗米亚地区)的贫血负担高于其他地区。母亲年龄在45岁以上(AOR=1.43(1.11-1.82),失业率(AOR=1.19;95%CI1.08-1.32),家庭财富指数(AOR=0.56;95%CI0.50-0.63),大家庭规模(AOR=1.20;95%CI1.04-1.46),和不使用计划生育(AOR=1.70;95%CI1.49-1.93)是与贫血相关的重要因素。贫血是一种中度的公共卫生问题,与位置和其他因素有关,需要通过有效的干预措施来解决。
    Globally one-third of global population are victims of anemia, significantly impacting maternal and infant health and linked to poor cognition, productivity, and mortality risks. We used randomly selected 4040 lactating mothers\' record from nationally representative survey. Descriptive statistics were weighted, and the standard hemoglobin cutoff point (below 12 g/dl) was used. Bivariable and multivariable multilevel binary logistic regression model considering the individual and community-level factors associated with anemia was employed. Crude and adjusted odds ratios with a 95% confidence interval were reported. In Ethiopia, 32.3% (95% CI 30.9-33.7%) of lactating women were anemic, with 23.4% having mild, 7.3% moderate, and 1.2% severe anemia. Pastoral regions (Afar, Somalia, and Oromia region) had higher burden of anemia than the others. The advanced age of the mother above 45 years (AOR = 1.43 (1.11-1.82), unemployment (AOR = 1.19; 95% CI 1.08-1.32), household wealth index (AOR = 0.56; 95% CI 0.50-0.63), extended family size (AOR = 1.20; 95% CI 1.04-1.46), and not using family planning (AOR = 1.70; 95% CI 1.49-1.93) were significant factors associated with anemia. Anemia is a moderate public health problem and associated with location and other factors to be addressed via effective interventions.

    哺乳动物的肠道微生物群携带复杂的微生物共生组合。从乳腺喂养新生婴儿的牛奶可以将亲代牛奶微生物组垂直传播到后代的肠道微生物组。这有好处,但对宿主人口也有危害。使用数学模型,我们证明,双亲垂直传播使有害的微生物元素入侵宿主种群。相比之下,单亲垂直传播充当筛子,阻止这些入侵。此外,我们表明,有害的共生体会对宿主修饰基因产生选择,从而使单亲传播保持不变。由于胎盘哺乳动物在出生时发生微生物传播,牛奶微生物组的后续传播需要是母体的,以避免有害元素的传播。因此,本文认为,胎生性和牛奶微生物组的双亲传播的危害,在胎盘哺乳动物中共同产生针对雄性泌乳的选择。
    Gut microbiomes of mammals carry a complex symbiotic assemblage of microorganisms. Feeding newborn infants milk from the mammary gland allows vertical transmission of the parental milk microbiome to the offspring\'s gut microbiome. This has benefits, but also has hazards for the host population. Using mathematical models, we demonstrate that biparental vertical transmission enables deleterious microbial elements to invade host populations. In contrast, uniparental vertical transmission acts as a sieve, preventing these invasions. Moreover, we show that deleterious symbionts generate selection on host modifier genes that keep uniparental transmission in place. Since microbial transmission occurs during birth in placental mammals, subsequent transmission of the milk microbiome needs to be maternal to avoid the spread of deleterious elements. This paper therefore argues that viviparity and the hazards from biparental transmission of the milk microbiome, together generate selection against male lactation in placental mammals.

    在过去的几十年中,英国的乳制品生产经历了重大的重组。农业集约化导致农场和牲畜总数减少,而每个持股的平均牛群规模有所增加。这些千变万化的环境对奶牛的健康和福利有着重要的影响,以及农场的整体经营业绩。对于奶牛养殖的决策,了解低效率的根本原因及其相对影响至关重要。对奶牛产量差距的调查一直集中在具体原因上。然而,除了高估特定疾病影响的风险,这种方法不允许理解对总体的相对贡献,它也不允许理解这种差距在根本原因方面有多好的描述。以英国和威尔士的乳制品行业为例,这项工作使用基准方法和情景分析来估计由产量损失和卫生支出组成的损失差距。损失差距是通过将奶牛群的当前表现作为基线与假设奶牛产奶量的情景进行比较来估计的。生产成本,市场价格,死亡率,以及与卫生事件有关的支出。建立了确定性模型,由企业预算组成,奶牛是其中的单位,挤奶牛群和年轻的股票分开处理。当限制牛奶生产时,该模型估计,整个行业的年度亏损缺口为148英镑至2.27亿英镑。兽医服务和药品费用的降低,除了羊群更换费用之外,是估计的重要贡献者,两种方案之间存在一些差异。牛奶价格对估计产生了重大影响,牛奶产量的收入占亏损缺口的30%以上,当牛奶价格以表现最好的农场为基准时。这个框架为理解英国和威尔士奶牛的特定原因造成的相对负担提供了界限,确保因特定问题造成的估计损失的总和不超过所有原因造成的损失,健康或非健康相关。
    Dairy production in the UK has undergone substantial restructuring over the last few decades. Farming intensification has led to a reduction in the total numbers of farms and animals, while the average herd size per holding has increased. These ever-changing circumstances have important implications for the health and welfare of dairy cows, as well as the overall business performance of farms. For decision-making in dairy farming, it is essential to understand the underlying causes of the inefficiencies and their relative impact. The investigation of yield gaps regarding dairy cattle has been focused on specific causes. However, in addition to the risk of overestimating the impact of a specific ailment, this approach does not allow understanding of the relative contribution to the total, nor does it allow understanding of how well-described that gap is in terms of underlying causes. Using the English and Welsh dairy sectors as an example, this work estimates the Loss Gap-composed of yield losses and health expenditure - using a benchmarking approach and scenario analysis. The Loss Gap was estimated by comparing the current performance of dairy herds as a baseline with that of scenarios where assumptions were made about the milk production of cows, production costs, market prices, mortality, and expenditure related to health events. A deterministic model was developed, consisting of an enterprise budget, in which the cow was the unit, with milking herd and young stock treated separately. When constraining milk production, the model estimated an annual Loss Gap of £148 to £227 million for the whole sector. The reduction in costs of veterinary services and medicines, alongside herd replacement costs, were important contributors to the estimate with some variation between the scenarios. Milk price had a substantial impact in the estimate, with revenue from milk yield representing more than 30% of the Loss Gap, when milk price was benchmarked against that of the top performing farms. This framework provides the boundaries for understanding the relative burden from specific causes in English and Welsh dairy cattle, ensuring that the sum of the estimated losses due to particular problem does not exceed the losses from all-causes, health or non-health related.

    BACKGROUND: Effective breastfeeding is crucial for maternal and child health, particularly in low-resource settings like Ethiopia. It encompasses a range of skills and strategies, including proper latch, positioning, and frequency of feeding. These techniques not only ensure sufficient milk transfer but also foster bonding between mother and child, enhancing the breastfeeding experience. To effectively prioritize maternal and child health, it is crucial to comprehensively understand the prevalence and factors influencing effective breastfeeding nationwide. Therefore, this study aimed to provide a pooled prevalence of effective breastfeeding techniques and associated factors among lactating mothers in Ethiopia.
    METHODS: The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist, focusing on studies conducted in Ethiopia. We identified eight relevant studies through Google Scholar, Medline, PubMed, Scopus, and the Cochrane Library. Analysis was conducted using STATA version 11, and systematic data extraction employed a checklist to extract relevant data. I2 tests and the Cochrane Q test statistic were used to evaluate heterogeneity. To explore potential publication bias, Egger\'s weighted regression, Begg\'s test, and a funnel plot were utilized.
    RESULTS: We identified a total of 955 research articles. Eight studies meeting the eligibility criteria were incorporated into this meta-analysis and systematic review. The pooled prevalence of effective breastfeeding techniques was 41.99% [95% CI 32.16-51.81]. According to the results of the current meta-analysis, effective breastfeeding techniques were significantly associated with antenatal care follow-up [OR = 1.75, 95% CI 1.10-2.78], maternal educational status [OR = 2.70, 95% CI 1.55-4.71], breastfeeding technique counseling [OR = 2.02, 95% CI 1.41-2.90], the absence of breast problems [OR = 2.26, 95% CI 1.49-3.43], breastfeeding experience [OR = 1.98, 95% CI 1.14-3.46], and immediate skin-to-skin contact [OR = 2.32, 95% CI 1.56-3.44].
    CONCLUSIONS: Our findings highlight the vital role of various factors in shaping effective breastfeeding.
    CONCLUSIONS: To improve practices and health outcomes, we recommend targeted interventions, such as strengthening antenatal care, implementing maternal education, and providing comprehensive breastfeeding counseling. Proactively addressing breast problems and prioritizing immediate skin-to-skin contact is crucial for successful breastfeeding.
