At the Central Duck Breeding Farm Hajiganj in Narayanganj, Bangladesh, morphometrics, productive, and reproductive performances of Deshi black and Deshi white ducks were measured under intensive conditions. Body length, head length, bill length, neck length, feather length, and shank length of mature male and female Deshi black and Deshi white ducks measured 59.56 ± 0.87 cm and 61.87 ± 0.48 cm, 2.25 ± 0.12 cm, and 3.4 ± 0.06 cm, 5.86 ± 0.12 cm, and 6.23 ± 0.06 cm, 19.21 ± 0.47 cm and 21.08 ± 0.26 cm, 21.85 ± 0.53 cm and 26.71 ± 0.29 cm, 9.93 ± 0.29 cm and 10.81 ± 0.16 cm, respectively. Morphometric features were significantly (p < 0.01, p < 0.05) higher in females than males. But no significant differences (p > 0.05) were detected between the two types of ducks except for the body, head, and feather length (p < 0.01, p < 0.05). At a day old, 4th week, 8th week, and 12th week of age, the body weights (LSMean ± SE) of male and female Deshi black and Deshi white ducks were 42.65 ± 0.35 gm and 43.40 ± 0.35 gm, 318.00 ± 9.13 gm and 319.04 ± 9.13 gm, 835.85 ± 8.94 gm and 794.20 ± 8.94 gm, 1345.80 ± 2.67 gm and 1347.90 ± 2.67 gm, respectively (gm = gram). Females were substantially heavier than males at 8 weeks of age (p < 0.01), but there was no significant difference in body weights between the two types of ducks (p > 0.05) until the 12th week of age (p < 0.01). Deshi black and Deshi white ducks reached sexual maturity at 136.0 ± 0.52 and 139.0 ± 0.52 days, respectively, and had 67.62 ± 0.83% and 63.18 ± 0.83%, 63.63 ± 0.56%, and 59.42 ± 0.56% fertility. Deshi black ducks had a substantially higher age at sexual maturity, fertility, and hatchability percentage (%) than Deshi white ducks (p < 0.01). For Deshi black and Deshi white, the egg weight, female weight at 1st lay, and egg weight at 1st lay were 66.69 ± 0.49 gm and 66.78 ± 0.49 gm, 1439.55 ± 6.98 gm and 1422.0 ± 6.98 gm, 48.90 ± 0.18 gm and 47.12 ± 0.18 gm, respectively. Deshi black duck egg weight was considerably (p < 0.01) higher than Deshi white duck egg weight at first lay. Deshi black and Deshi white ducks produced 214.65 and 211.402.65 eggs per year, respectively (p > 0.05). The study's findings gave some baseline information on Bangladesh's Deshi black and Deshi white ducks, which could benefit conservation and future enhancement efforts.

The aim of this study was to determine if multiple captures, general anesthesia and electroejaculation (EE) modify the heart rate (HR), pulse rate (PR), respiratory rate (RR), rectal temperature (RT), oxygen saturation, and the cortisol, alkaline phosphatase (AP) and creatine kinase (CK) responses to EE in adult and yearling pampas deer (Ozotoceros bezoarticus) males. Individuals were captured, anesthetized and electroejaculated on four occasions, once per season, from June to the following March (first to fourth collection respectively). Rectal temperature, as well as cortisol, AP and CK serum concentrations were determined before and after electroejaculation (BEE and AEE). The HR (P < 0 0.0001), PR (P < 0.0001), RR (P < 0.001), CK (P < 0.001) and cortisol concentration (P = 0.003) increased AEE, while RT (P = 0.004) decreased AEE. Heart rate increased in the first and third collections (P < 0.01), RR increased in the fourth collection (P < 0.001), and the highest values of RT were observed in the third and fourth collections (P < 0.0001). We concluded that repeated handling to collect semen did not have a sustained negative effect on the response to EE, which supports repeated semen collection from the same individuals.

本研究的目的是确定多次捕捉、全身麻醉和电射精（EE）是否会改变成年和一岁的潘帕斯鹿（Ozotoceros bezoarticus）雄性的心率（HR）、脉搏率（PR）、呼吸频率（RR）、直肠温度（RT）、氧饱和度以及皮质醇、碱性磷酸酶（AP）和肌酸激酶（CK）对EE的反应。从6月到次年3月，对个体进行四次捕获、麻醉和电射精，每个季节一次（分别为第一次至第四次采集）。在电射精（BEE和AEE）前后测定直肠温度以及皮质醇、AP和CK的血清浓度。HR（P＜0.0001）、PR（P＜0.001）、RR（P＜0.01）、CK（P＜0.005）和皮质醇浓度（P＝0.003）增加了AEE，而RT（P＝0.002）降低了AEE。第一次和第三次采集时心率增加（P<；0.01），第四次采集时RR增加（P>；0.001），第三次和第四次收集时RT值最高（P<！0.0001）。我们得出结论，重复处理精液采集对EE的反应没有持续的负面影响，其支持从相同个体重复采集精液。

Vitamin A is one of the fat-soluble vitamins that participates in metabolic processes of great importance and, as it is not enough produced by the body, it is essential to compose a diet. An experiment was carried the to determine the levels of vitamin A (Retinol) for meat quails (Coturnix coturnix sp), from 1 to 35 days of age, divided in two production periods, from 1 to 14 days and 15 to 35 days using seven different levels of vitamin A inclusion on the diets. Feed intake (FI) and accumulated body biomass (ABB) had linear effect while the body weight (BW), weight gain (WG), feed conversion (FC) showed a quadratic effect (P < 0.05) during the first period. The weight gain (WG) and accumulated body biomass (ABB) showed a quadratic effect (P < 0.05) for the second period, while the body weight (BW) increased linearly on the same phase. No significant differences were observed (P > 0.05) for hematocrit (HEM), the relative values of heterophils (H), lymphocytes (L), heterophil/lymphocyte ratio (H:L), serum enzymes aspartate aminotransferase (AST), alanine aminotransferase (ALT) and absolute liver weight (W liver). The absolute weight of Fabricius bursa (W bursa) showed a quadratic effect (P < 0.05), and absolute weight spleen (W spleen) was linearly influenced. In relation to the relative weight, only the spleen (Rw spleen) was influenced by the supplementation level of supplementation, it was observed that this supplementation has little effect on immunity of meat quails of 1–14 days old. The estimating levels of vitamin A were 3.35; 3.38 and 2.11 mg/kg to the period of 1 to 14 days and 2.82 and 2.67 mg/kg to the period of 15 to 35 days, respectively.

维生素A是一种脂溶性维生素，参与重要的代谢过程，由于身体产生的维生素A不足，因此必须制定饮食。进行了一项实验，以测定肉鹌鹑（Coturnix Coturnix sp）的维生素A（视黄醇）水平，从1到35 年龄天数，分为两个生产期，从1到14 15至35天 在饮食中使用七种不同水平的维生素A。采食量（FI）和累积体生物量（ABB）呈线性效应，而体重（BW）、增重（WG）、饲料转化率（FC）呈二次效应（P <； 0.05）。增重（WG）和累积体生物量（ABB）呈二次效应（P <； 0.05），而体重（BW）在同一阶段线性增加。差异无统计学意义（P >； 0.05）血细胞比容（HEM）、嗜异细胞（H）、淋巴细胞（L）、嗜异性/淋巴细胞比率（H:L）、血清酶天冬氨酸转氨酶（AST）、丙氨酸转氨酶（ALT）和绝对肝重（W肝）的相对值。法氏囊绝对重量呈二次效应（P <； 0.05）和绝对重量脾脏（W脾脏）受到线性影响。就相对重量而言，只有脾脏（Rw脾脏）受到补充水平的影响，观察到这种补充对1-14岁肉鹌鹑的免疫力几乎没有影响 天以前。维生素A的估计水平为3.35；3.38和2.11 mg/kg至1至14 天和2.82和2.67 mg/kg至15-35 天。

The study aimed to evaluate the effects of the kids’ number and sex on the thyroid and lipidic patterns of 30 dairy goats in the advanced mid-gestation and from 30 to 105 days of lactation.

Blood samples were monthly collected to measure circulating thyroid stimulating hormone (TSH), total and free triiodothyronines (T₃, fT₃) and thyroxines (T₄, fT₄); triglyceride (TG), total cholesterol (tCho), and very-low-density lipoprotein cholesterol (VLDL Cho).

Dams carrying a single foetus showed higher T₄ concentrations (P < 0.04) at >130–150 days than those carrying twins. Dams carrying one/two males had the highest fT₃ (P < 0.001) and fT₄ (P < 0.03) concentrations at 95–115 days and the highest fT₃ (P < 0.0001) and TSH (P < 0.002) at >115–130 days. Dams kidding male and female twins showed the highest TG and VLDL Cho concentrations (P < 0.04) at >70–105 days of lactation.

Single or twin births influenced the thyroid activity of pregnant goats, with a specific effect of foetal number on T₄ and of foetal sex on fT₃ and fT₄ concentrations. Kids’ number and sex affected TG and VLDL Cho in lactating dams. This suggests that foetal number and sex are not a random chance event but an interactive process between maternal and foetal endocrine and metabolic processes.

本研究旨在评估30只妊娠中期和哺乳期30-105天的奶山羊的数量和性别对甲状腺和血脂模式的影响。每月采集血样以测量循环促甲状腺激素（TSH）、总的和游离的三碘甲状腺原氨酸（T3，fT3）和甲状腺素（T4，fT4）；甘油三酯（TG）、总胆固醇（tCho）和极低密度脂蛋白胆固醇（VLDL-Cho）；130–150天。携带1/2只雄性的水坝在95–115天时具有最高的fT3（P＜0.001）和fT4（P＜0.03）浓度，在>；115–130天。开玩笑的雄性和雌性双胞胎在>；哺乳期70–105天。单胎或双胎出生会影响怀孕山羊的甲状腺活性，胎儿数量对T4有特定影响，胎儿性别对fT3和fT4浓度有特定影响。哺乳期母鼠的儿童数量和性别影响TG和VLDL Cho。这表明，胎儿数量和性别不是一个随机的偶然事件，而是母体和胎儿内分泌和代谢过程之间的互动过程。

To the best of our knowledge, there are no previous studies on a surgical approach for lesions in the pterygoid sinus of dolphins as it lies deep in the oropharyngeal area and there is risk of bleeding. For such lesions, we undertook a surgical approach for dolphins under general anesthesia. The line of incision was located on the oral mucosa anterior to the palatine bone. A surgical approach with needle biopsy was used to reach the lesion in the pterygoid sinus from within the crest of the pterygoid. Subsequently, this approach was confirmed to be minimally invasive, simple, and safe for dolphins with lesions in the pterygoid sinus.

据我们所知，以前没有关于海豚翼窦病变的手术方法的研究，因为翼窦位于口咽深处，有出血的风险。对于这种病变，我们在全身麻醉下对海豚进行了手术治疗。切口位于腭骨前方的口腔粘膜上。采用针活检的手术方法从翼嵴内到达翼窦的病变。随后，这种方法被证实对翼窦病变的海豚来说是微创、简单和安全的。

Objectives

This study was performed to evaluate the effectiveness of ultrasound-guided injections in lesions of suspensory ligament branches of an autologous standardized leukocyte poor platelet-rich plasma.

Methods

Nine sport horses with front legs suspensory ligament branch desmopathies (SLBD) were included in the study. A clinical examination and ultrasound evaluation of the affected suspensory ligament branches were carried out at the time of inclusion and on a monthly basis for 6 months after the first platelet-rich plasma (PRP) injection. Twelve branches were treated with 2–3 injections spaced by 2 weeks. Long-term follow-up at 12 months and up to 24 months for 6 horses were carried out by means of telephonic interviews with the owner.

Results

Ten out of 12 branches presented resolution of the hypoechoic lesions within three months and the treatment was associated with rapid resolution of lameness. Six of the 9 horses returned to their previous workload, 2 were in a lower level and 1 was retired.

Conclusions

Two to three intralesional injections with RegenPRP in SLBD contributes to a rapid resolution of lameness and ultrasonographic lesions without complications. This treatment should be considered to increase the number of horses reaching their previous level of performance. Clinical results confirm that the use of a standardized autologous leukocyte poor PRP represents a convenient alternative treatment for SLB lesions.

目的本研究旨在评价超声引导下注射治疗自体标准化贫白细胞富血小板血浆悬韧带分支病变的有效性。方法对9匹患有前腿悬吊韧带分支桥连病（SLBD）的运动马进行研究。在纳入时每月对受影响的悬吊韧带分支进行6次临床检查和超声评估 在第一次富血小板血浆（PRP）注射后数月。12个分支接受2-3次注射，间隔2次 周。12岁时的长期随访 月至24 对6匹马进行了为期数月的电话采访。结果12个分支中有10个分支在3个月内表现出低回声病变的消退，治疗与跛行的快速消退有关。9匹马中有6匹马恢复了以前的工作量，2匹马处于较低级别，1匹马退役。结论在SLBD中，两到三次病灶内注射RegenPRP有助于快速解决跛行和超声病变，而不会出现并发症。这种治疗应该考虑增加达到先前水平的马匹数量。临床结果证实，使用标准化的自体低白细胞PRP是SLB病变的一种方便的替代治疗方法。
