- We examined differences in slaughter performance and meat quality of Honghe yellow cattle of different ages. We randomly selected nine Honghe bulls for slaughter at 12 (12M), 36 (36M), and 60 (60M) months of age. There were significant differences in antemortem live weight, carcass weight, and net weight among the three groups, all of which increased with age. Backfat thickness in 36M (4.77±0.25 mm) and 60M (5.50±0.50 mm) was significantly higher than in 12M (3.00±0.00 mm), and the loin-eye area in 60M (68.02±16.02) was higher than in 12M (27.01±1.89). There was no significant difference in the pH value of the month-old group. Compared with 12M (29.33±4.93%) and 60M (23.87±5.08%), the cooking loss of meat in 36M (36.50±5.07%) was significantly higher; meanwhile, a* value was also the highest in 36M (22.39±1.34), the protein and fat content of muscle in 12M was lower, while the content of meat in 60M was lower. There was no significant difference in muscle ash, Ca, and P contents; the total amino acid and essential amino acid contents of 36M were higher than those of 12M and 60M, and the unsaturated fatty acids of meat in 12M were higher than those in 36M and 60M. The change of age has a certain influence on the slaughter performance and meat quality of Honghe yellow cattle.
——考察不同年龄红河黄牛屠宰性能和肉质的差异。随机选取12月龄、36月龄和60月龄的9头红河公牛进行屠宰。三组间的活重、胴体重和净重差异显著,均随年龄增长而增加。背膘厚度36M(4.77±0.25 mm)和60M(5.50±0.50 mm)显著高于12M(3.00±0.00 mm),腰眼面积60M(68.02±16.02)显著高于12M(27.01±1.89)。月龄组pH值差异无统计学意义。与12M(29.33±4.93%)和60M(23.87±5.08%)相比,36M的蒸煮损失(36.50±5.07%)显著高于12M(29.33±4.93%)和60M(23.87±5.08%);同时,a*值在36M也最高(22.39±1.34),12M肌肉蛋白质和脂肪含量较低,60M肉质含量较低。肌灰分、钙、磷含量差异不显著;36M的总氨基酸和必需氨基酸含量高于12M和60M, 12M的不饱和脂肪酸含量高于36M和60M。年龄的变化对红河黄牛的屠宰性能和肉质有一定的影响。

- The potential of royal jelly production in Africanized honeybee colonies was evaluated using techniques involving two queens per colony in horizontal and vertical systems during the spring of 2019. The techniques were tested for their effect on cell acceptance (%); royal jelly production per colony (g), per harvest (g), and per position of cell bar (g) and compared with standard techniques (five and ten-frame hives) in southern Brazil. Results showed statistical significance in royal jelly production between methods. Vertical colonies produced a significantly greater amount of royal jelly per colony and per harvest (8.26 and 53.28±4.98 g) compared with single-queen colonies in ten-frame hives (4.30 and 32.76±3.57 g) and five-frame hives overlapping (2.03 and 14.45±2.48 g), but did not differ from two-queen horizontal colonies (8.09 and 46.81±4.90 g). In contrast, there was no significant difference in queen cell acceptance rate within vertical, horizontal, and ten-frame colonies. Royal jelly yield of two-queen vertical colonies increase as compared with standard colonies.
- 2019年春季,利用水平和垂直系统中每个蜂群两个蜂王的技术,评估了非洲化蜂群中蜂王浆生产的潜力。测试了这些技术对细胞接受度的影响(%);在巴西南部,蜂王浆的每菌落产量(g)、每次收获量(g)和每个细胞条位置(g),并与标准技术(五帧和十帧蜂箱)进行比较。结果表明,两种方法的蜂王浆产量具有统计学意义。垂直蜂群的蜂王浆产生量(8.26和53.28±4.98 g)显著高于单蜂群在十框蜂箱中的产生量(4.30和32.76±3.57 g)和五框蜂箱重叠的产生量(2.03和14.45±2.48 g),但与双蜂王水平蜂群的产生量(8.09和46.81±4.90 g)差异不显著,而在垂直、水平和十框蜂群中,蜂王细胞接受率无显著差异。与标准蜂群相比,双蜂王垂直蜂群蜂王浆产量增加。

- This study aimed to evaluate the effects of ground or steam-flaked corn and zinc-enriched yeast addition to grower pellet feed on fattening performance, rumen papillae development, and some blood parameters in lambs. For this purpose, thirty-six Kivircik male lambs were selected and divided equally into six groups: basal diet containing pellet feed without different corn form and yeast (control), basal diet 80% + ground corn 20% (PGC), basal diet 80% + steam-flaked corn 20% (PFC), PGC + Zn-enriched yeast (PGCZnY), PFC + Zn-enriched yeast (PFCZnY), and control + Zn-enriched yeast (PZnY). They were fed for 56 days according to the diets mentioned above. At the conclusion of the evaluations in fattening performance, rumen papillae development, and some blood parameters, there were no significant differences in body weight gain, average daily gain, average daily feed intake, and feed efficiency among the experimental groups. In the PGCZnY group, rumen papillae length was found to be higher than the other experimental groups. At the end of the trial (day 0), leukocyte and lymphocyte counts decreased significantly only in the control group compared with the other groups in the present study. Serum blood urea nitrogen (BUN) values, analyzed at the beginning and at the end of the trial, increased significantly in all groups except in the PGCZnY group. Supplementation of Zinc-enriched yeast to ground corn can be used for increasing ruminal papilla length, however decreasing the serum BUN levels in lambs during the fattening
本研究旨在评价在生长颗粒饲料中添加磨碎或蒸汽片玉米和富锌酵母对羔羊增肥性能、瘤胃乳头发育和某些血液参数的影响。选取36只基维西克公羔羊,随机分为6组:基础饲粮中不含不同玉米形态和酵母的颗粒饲料(对照)、基础饲粮80% +磨碎玉米20% (PGC)、基础饲粮80% +蒸片玉米20% (PFC)、PGC +富锌酵母(PGCZnY)、PFC +富锌酵母(PFCZnY)和对照+富锌酵母(PZnY)。按上述日粮饲喂56 d。通过对育肥性能、瘤胃乳头发育及部分血液参数的评价,各试验组的增重、平均日增重、平均日采食量和饲料效率均无显著差异。PGCZnY组瘤胃乳头长度明显高于其他试验组。在试验结束时(第0天),与本研究的其他组相比,只有对照组的白细胞和淋巴细胞计数明显下降。试验开始和结束时,除PGCZnY组外,其余各组血清尿素氮(BUN)值均显著升高。在玉米粉中添加富锌酵母可增加瘤胃乳头长度,但会降低育肥羔羊血清BUN水平

The objective was to evaluate the effect of different irrigation systems and harvest frequencies on the cultivation of cactus pear. The study was conducted in the semi-arid region, in the municipality of Russas, CE, Brazil. The experiment was a split plot randomized block design, with four replications. Plots were represented by irrigation systems (surface drip, microsprinkler, Micro Spray Jet, and conventional sprinkler) and subplots by harvest frequencies (6, 9, 12, and 18 months). Cactus pear biomass production characteristics were evaluated. Most of the productive characteristics evaluated were influenced by harvest frequency and irrigation system. The harvest frequency of 12 months combined with conventional sprinkler system resulted in a total dry biomass production of 16,400 kg ha−1. The conventional sprinkler system showed the highest number of second-order cladodes (4.9 cladodes plant−1). The conventional sprinkler and Micro Spray Jet systems showed the highest values for various structural characteristics. For water use efficiency (WUE), the highest value was found at the frequency of six months (8.46 kg ha−1 mm−1). Regarding the effects of irrigation system on WUE, the highest values were observed with the conventional sprinkler system (8.20 kg ha−1 mm−1). The harvest frequency of 12 months combined with the conventional sprinkler system presents better results in the evaluated productive characteristics, mainly the cactus pear production by area.
目的是评价不同灌溉制度和收获频率对仙人掌梨栽培的影响。这项研究是在半干旱地区进行的,在巴西东部的俄罗斯市。试验采用分图随机区组设计,共4个重复。小区采用灌溉系统(地表滴灌、微喷灌、微喷喷和常规喷灌),小区按收获频率划分(6、9、12和18个月)。对仙人掌、梨的生物量生产特性进行了评价。所评价的大部分生产特性受收获频率和灌溉制度的影响。12个月的收获频率与传统的洒水系统相结合,导致总干生物质产量为16,400 kg ha - 1。传统喷淋系统的二级枝枝数量最多(4.9枝枝plant−1)。传统喷淋系统和微喷淋系统在各结构特性上均表现出最高的值。在水分利用效率(WUE)方面,6个月的频率最高(8.46 kg ha−1 mm−1)。关于灌溉系统对水分利用效率的影响,传统喷水系统的水分利用效率最高(8.20 kg ha - 1 mm - 1)。12个月采收频率与常规洒水系统相结合,在评价生产特征上效果较好,以仙人掌梨的面积产量为主。

- The objective of this study was to characterize and understand the investment profile towards technologies for control and automation of climate control on swine farms, focused on integrated producers on the same integration system. A structured questionnaire including open, dichotomic, or multiple-choice questions was responded by 190 integrated producers classified as nursery (28,300 swines), wean-to-finish (WTF; 144,388 swines), or finishing unit (FU; 164,185 swines) farms. Data were described and categorized according to the type of integrated producer (nursery, WTF, and FU) and income history during a 24-month interval. The most predominant farmer profile was of a 44.5-year-old man, with incomplete secondary education. Furthermore, the majority of the farms had family-based labor with an average area of 43.6±65.5 ha and ~2.4 economic activities developed. Overall, a reduced labor availability was observed, although the integrated producers declared to be satisfied with the activities. Interestingly, integrated producers with a better income history declared a longer working (high = 37; average = 31; regular = 31; low = 28 min). The investment profile in automation technologies is conservative; however, potential improvements in pig performance were the most popular justification for potential investments. Furthermore, high costs, knowledge in technologies, interest rates, and quality of the available material are the limiting factors for investing in environment control. A total of 74% of the integrated producers considered the activity as economically profitable. Lastly, the uptake of environmental control technologies is strongly associated with the average income received by farmers.
-本研究的目的是描述和了解猪场气候控制和自动化技术的投资概况,重点关注同一集成系统的综合生产者。190个综合生产商回答了一份结构化问卷,包括开放式、二选法或多项选择题,这些生产商被划分为苗圃(28,300头猪)、断奶至育肥猪(WTF);144,388头猪),或精加工单位(FU;164,185头猪)农场。根据综合生产者的类型(苗圃、WTF和FU)和24个月的收入历史对数据进行描述和分类。最主要的农民特征是44.5岁的男性,中等教育程度不高。以家庭劳动力为主的农场居多,平均面积为43.6±65.5 ha,有经济活动约2.4个。总的来说,观察到劳动力可用性减少,尽管综合生产者宣布对这些活动感到满意。有趣的是,拥有较好收入历史的整合生产商的工作时间更长(高= 37;平均= 31;Regular = 31;低= 28分钟)。自动化技术的投资概况是保守的;然而,猪生产性能的潜在改善是潜在投资最普遍的理由。此外,高成本、技术知识、利率和可用材料的质量是投资于环境控制的限制因素。74%的综合生产商认为该活动具有经济效益。最后,采用环境控制技术与农民的平均收入密切相关。
