中国饲料行业信息网
进入2023年，各大养猪上市企业陆续公布2022年12月份生猪出栏数据，随着年底收官，年度出栏数据也随之出炉，猪场动力网通过总结16家上市猪企数据简报，分别从出栏量、出栏增速、目标完成率、销售价格、养殖成本等5个维度对其进行总结及盘点。生猪出栏量排名，牧原遥遥领先。先看出栏量排名情况，2022年，16家企业合计出栏量为12920万头，其中有3家企业出栏量过千万，牧原6120.1万头遥遥领先，其出栏量接近另外15家企业总和，若按照2021年全国生猪出栏量67128万头计算，牧原占比也达到的9.1%。温氏股份以1790.86万头排名第二，新希望以1461.39万头排名第三，出栏量超百万的企业达到12家。由于本文只统计上市猪场，双胞胎、正大、德康三大集团虽非上市公司，但根据其2021年出栏量以及2022年底能繁母猪数和PSY水平，其年度出栏量都将位列全国前列。

Background：Dietary supplementation of full-fat black soldier fly larvae (BSFL full-fat meal; alone or in combination with multi-probiotics) was tested as an alternative to dietary antibiotics in weaning piglets. We also tested the effects of these diets on growth performance, nutrient digestibility coefficients, immune status, oxidative stress, intestinal histomorphology, and rectal microbial modulations in weaned pigs. A total of 80 piglets [(Landrace × Large White) × Duroc] of both sexes (a ratio of gilts and barrows; 1:1), were randomly allotted to four diet groups: positive control (PC) diet supplemented with 0.02% amoxicillin; negative control (NC) diet without supplement addition; BSFL12 diet (NC + 12% BSFL full-fat meal); and BSFL + Pro diet (BSFL full-fat meal + 0.1% multi-probiotics, including Bacillus subtilis, B. licheniformis, and Saccharomyces cerevisiae). All groups had five replicates, with four piglets per replicate. Results：Dietary BSFL + Pro improved the overall average daily gain (P = 0.013), and gain-to-feed ratio (P = 0.032). The BSFL12 and BSFL + Pro diets improved nutrient digestibility and increased the serum levels of immunoglobulin A and glutathione peroxidase, while reducing the levels of pro-inflammatory cytokines. The spleen weight was higher and caecal pH was lower in pigs fed the BSFL + Pro diet than in those fed the NC diet (P = 0.011 and P = 0.021, respectively). Pigs fed the BSFL diets had longer duodenal villi, a higher villus height-to-crypt depth ratio (P = 0.004), and shorter crypt depth (P = 0.017) than those fed NC. The BSFL + Pro diet also increased faecal Lactobacillus spp. count (P = 0.008) and reduced Escherichia coli (P = 0.021) counts compared with that seen with PC and NC diets, respectively. Conclusions：Dietary supplementation with BSFL or BSFL + multi-probiotics can improve the growth performance and intestinal health of pigs and may be an effective strategy to replace antibiotics for weaned pigs.

The cost of feed is the most important cost in pig production (60-70%) and the energy component represents the greatest proportion (more than 80%) of that cost. Protein and minerals supply in feed are less expensive but crucial for performance of animals and levels of wastes and potential pollutions in the environment. Therefore, it is important to precisely estimate the nutritional value of feeds, either for least-cost formulation purposes (ingredients) or for adapting feed supply to requirements of animals (complete feeds). In addition, new and alternative feed ingredients, and new technologies (enzymes, for instance) are used and their impacts must be evaluated. Not all gross energy (GE) of a feed is available for meeting the requirements of animals since variable proportions of GE are lost in excreta (feces and urine), as fermentation gases (methane, hydrogen) and as heat (or heat increment; HI). The digestible energy (DE) content of a feed is equal to its GE content minus fecal energy losses, the latter ones being related to the levels of dietary fiber in the feed. The metabolizable (ME) content of a feed corresponds to the difference between the DE content and energy losses in urine and gases. Urinary energy is directly dependent on dietary nitrogen content. Methane production is very small and negligible in growing pigs, but it should be considered in adult pigs. Energy digestibility (DE/GE) increases with body weight (BW) increases in pigs, with the highest difference between adult pigs (reproductive sows) and young growing pigs. The change is more accentuated for high dietary fiber feeds. The practical consequence of these variations is that DE or ME values should vary with BW or the physiological stage in pigs. Technologies such as pelleting or extrusion or the supplementation with enzymes are used routinely in the preparation of feeds. They have usually a positive effect on nutrients and energy digestibility. Unfortunately, these effects are documented for only a few ingredients and insufficiently considered in feeding tables and in least-cost formulation.

2022年猪肉产量预计增幅较明显，市场情绪影响出栏节奏。从国内生产来看，预计全年猪肉产量较上年增5.9%，供给量预计较上年增1.9%。总体来看，市场情绪对三季度和四季度出栏节奏影响显着，导致供给出现明显后置的特征。从不同季度来看，一季度同比增幅较大。从不同月份屠宰量来看，3-4月份同比激增超过50%，5月份开始环比下降，7月份同比下降，11月份环比明显增长，同比降幅明显收窄，预计12月份或同比略高于上年同期。从供给来看，2023年总体预计与2022年基本持平略增。2022年4月能繁母猪存栏是低点，之后持续增长，四季度能繁母猪高于4300万头的合理产能的上限约90万头左右。从平均值来看，2022年能繁母猪存栏低于2021年但psy提高1头左右因此总体来看，2023年生猪出栏量预计因效率提高高于2022年，但从出栏量重来看，预计2023年猪肉产量持稳略增。从进口方面，2023年进口形势会有增加，进口猪肉200万吨左右。综合来看，供给量持平略增
[前沿资讯 ] USDA-ERS：预计中国仍将是美国农产品出口的最大市场 进入全文
国际畜牧网
根据美国农业部经济研究局（USDA-ERS）的数据，美国2023财年的农产品出口值预计为1900亿美元，比8月份的预测减少了35亿美元。ERS说，这种下降主要是由于大豆、棉花和玉米出口的减少，部分被牛肉、家禽和小麦的增长所抵消。报告说，由于产量减少和来自南美的竞争加剧，大豆出口预计减少24亿美元，至328亿美元。棉花出口预计将下降10亿美元，至60亿美元，原因是单位价值下降和需求疲软。谷物和饲料出口预计将减少3亿美元，至462亿美元，其中玉米、高粱和大米出口的下降部分被小麦、饲料和饲料出口的增加所抵消。由于产量下降，玉米的预期出口值下降了6亿美元，至185亿美元。牲畜、家禽和乳制品出口预计将增加3亿美元，达到414亿美元，因为牛肉、家禽和各种肉类出口的增长抵消了猪肉和乳制品出口价值的下降。在价格上涨的推动下，牛肉出口增长了5亿美元，达到103亿美元。乙醇出口与8月份预测的42亿美元持平，如果这一预测实现，仍将是创纪录的。ERS指出，由于大豆、棉花、高粱和猪肉的出口前景较低，对中国的农产品出口预计为340亿美元，比8月份的预测减少了20亿美元。预计中国仍将是美国农产品出口的最大市场。预计2023年美国农产品进口为1990亿美元，比8月的预测增加20亿美元，主要是由于园艺产品、糖和热带产品以及谷物和饲料产品进口增加。ERS表示，强势美元虽然不利于出口预测，但也是进口需求上升的部分原因。
