The effects of dietary sodium butyrate (SB) and Saccharomyces cerevisiae (SC) on some bodily parameters of chickens were evaluated. One hundred and twentyday-old broilers (CHI, Ajanla Farms,Ibadan, Nigeria) were randomly divided into four treatments A, B, C and D, consisting three replicate pens of 10 chickens. They were fed as follows: A-diet withoutsupplement (control); B-(200mg/kg SB); C-(200mg/kg SB+1.0g/kg SC), and D-(1.0g/kg SC). Growth performance, organ weights, carcass quality, and lipid profile were determined. Intestinal villus height(VH), villus width (VW), villus surface area (VSA), crypt depth (CD), villus height to crypts depth ratio (VH: CD) were assessed. Some selected bacteria population, haematology, serum biochemistry and humoral immune responses against NDV and SRBCs antigens were evaluated. Supplementation increased growth performance, bursa and thymus weights. There was significantly (p<0.05) higher dressing percentage and lower cholesterol in groups B and C. High density lipoprotein and triglyceride were reduced significantly in B. Triglyceride and abdominal fat were significantly higher inD. The CD was higher (p<0.05) in duodenum of the control. In supplemented groups, VSA and VH: CD in the threeintestinal segments, VH in duodenum and jejunum were enhanced. Supplementation lowered gut microflora, increased WBC, lymphocyte counts and immune performance. DietC stimulated more positive influence on productive parameters and could be an alternative growth promoter in broilers.
评估了日粮丁酸钠（SB）和酿酒酵母（SC）对鸡的一些身体指标的影响。将 120 日龄肉鸡（CHI，Ajanla Farms，Ibadan，Nigeria）随机分为 A、B、C 和 D 四种处理，每栏 10 只鸡，三组重复。饲喂方法如下A-日粮无添加剂（对照组）；B-（200 毫克/千克 SB）；C-（200 毫克/千克 SB+1.0 克/千克 SC）；D-（1.0 克/千克 SC）。测定了生长性能、器官重量、胴体质量和脂质概况。评估了肠绒毛高度（VH）、绒毛宽度（VW）、绒毛表面积（VSA）、隐窝深度（CD）、绒毛高度与隐窝深度比（VH：CD）。还评估了一些特定细菌的数量、血液学、血清生化学以及对 NDV 和 SRBC 抗原的体液免疫反应。补充营养提高了生长性能、法氏囊和胸腺重量。B 组的高密度脂蛋白和甘油三酯明显降低，D 组的甘油三酯和腹脂明显升高。对照组十二指肠中的 CD 更高（p<0.05）。补充营养组的 VSA 和 VH：三个肠段的 CD、十二指肠和空肠的 VH 均有所提高。补充剂降低了肠道微生物菌群，增加了白细胞、淋巴细胞计数和免疫表现。日粮 C 对生产性能参数有更积极的影响，可作为肉鸡的替代生长促进剂。

There are a large number of previous researches on the effects of listening to music for different species, including humans, dairy cows, wild animals in captivity and even dogs.1 Dogs can be kept in kennels for a variety of reasons, such as laboratory purposes, housing work-dogs or in shelters. The life in a shelter means physical and social restraint, therefore dogs generally show the signs of stress after having arrived in it.2 The supply with toys improved only the state of experimental dogs, but not for kennel ones.3 The influence of displaying human voice is not clear:4 while Wells et al.,5 found the radio ineffective, on the other hand, the listening of audio books proved to be beneficial.6 The general mood of dog is influenced by the type of the music, too. In a study with 117 dogs the heavy metal music caused nervousness and trembling.7 On the other hand, a series of different genre of music (motown, soft rock, pop, reggae and classical) was able to decrease the stress level of dogs. The most powerful were the soft rock and the reggae, but the no musical treatment mitigated the barking. Owing to the individual differences in the taste of the animals, the deviation of data was big.4 This phenomenon is known in human, too.8 The shelters are noisy premises, therefore the use of a well-chosen background music may do a lot of good. The purpose of this research was to reduce general stress level of dogs.

The purpose of this study is to compare clinical results in horses with a reinjury of the superficial digital flexor tendon (SDF) treated with desmotomy of the accessory ligament of SDF or with “counterirritation” through a blister ointment. Horses have been divided into two groups: Group 1-horses treated with surgery; Group 2 horses treated with the application of a blister ointment. The results have shown in Group 1 one horses had a recurrent injury to the SDF after the second competition, instead in Group 2 one horse had a recurrent injury to the SDF after the third competition, one after the first and one after the second. In the present study no statistically significant differences (P=0,058) were detected between the two groups in terms of performance and reinjury incidence for about five competitions.

The objective of this research was to determine future directions the Southwest Regional Dairy Center (SWRDC) should take and improvements the SWRDC could make. In October 2019, a Qualtrics survey (Qualtrics LLC., Provo, Utah) was distributed to the Texas Association of Dairymen to further distribute to dairy producers and industry representatives. The survey asked respondents to rank satisfaction with tours of the SWRDC from 1 to 7 (1=extremely satisfied, 7=extremely dissatisfied) and to rank community outreach events, research activities, extension events, and types of research from least important to most important. Twenty-eight producers and dairy industry representatives responded. Of the respondents, nine ranked the SWRDC tours as extremely satisfied, two ranked as moderately satisfied, two ranked as neutral and the remaining respondents did not answer the question. The respondents’ highest ranked community outreach events, research activities and extension events were breakfast on the farm, research showcase, and demonstration days with continuing education credits offered, respectively. The respondents’ highest ranked type of research was precision dairy monitoring technology. Survey results better inform the SWRDC administration of future directions the center should take in research, education, and service activities.

A feeding trial was conducted for 84 days followed by 7 days of fecal collection to determine performance and also digestibility of nutrients at Maichew ATVET College in Tigray, North Ethiopia using 24 yearling intact male local sheep grouped into six blocks of four sheep based on their initial body weight and each block assigned to each of the four treatments diets. The basal diet was composed of natural pasture hay (ad libitum), wheat bran (309 g/sheep/d) and salt (3 g/head/d) and test diet (graded levels of wet brewery grain by-product=WBGB). Treatment diets were: T1 (basal diet+0g WBGB/head/day), T2 (basal diet + 210g WBGB/head/day), T3 (basal diet + 280g WBGB/head/day) and T4 (basal diet + 350g WBGB/head/day). ANOVA of data was conducted using General Linear Model (GLM) procedures of SAS; and means compared using Tukey’s HSD test (p<0.05). Dry matter, organic matter and crude protein intake and digestibility significantly increased (p<0.05) with increasing levels of supplementation. Higher average daily body weight and feed conversion efficiency (p≤ 0.05) were recorded in T4 followed by T3, T2, and T1. Hot carcass weight (9-11 kg), rib eye muscle area as a sign of degree of muscling (7.20 -10.70cm2 ), net return and marginal rate of return (MRR) were higher (p<0.05) in supplemented than in T1 fed sheep, with best results in T4. It can be recommended that sheep can be supplemented up to 124 g dried BGB or 350 g WBGB because it gave better body weight and carcass performances and MRR.

Media components for the production of lignolytic enzyme MnP in the submerged fermentation from Clitopilus scyphoides were screened by PB design of experiments using main effects of different components and their percent contribution towards the MnP production. Total 31 components were considered in this study at temperature 30°C and incubation period of 5 days, in which Galactose, Malt extract, KH2 PO4 , NH4 H2 PO4 , CaCO3 , Tween80, Tartaric acid and sodium acetate were found to be significant components for MnP production. Further, response surface methodology was employed to optimize the media containing screened components along with temperature, pH and incubation days. The optimized medium contained 1.5% Galactose, 0.06%Malt extract, 0.02%KH2 PO4, 0.15%NH4 H2 PO4 , 0.003%CaCO3, 0.8%Tween80,0.005% MnSO4,0.88%Tartaric acid and 3% sodium acetate at temperature 31°C and pH 5.2 incubated for 5 days increased MnP productivity by 43 folds (43.2±1.29 U mL-1)when compared to un-optimized media (1.1±0.087 U mL-1). MnP produced was tested for lignolytic effects on different crop residues. Digestibility studies of different crop residues treated with crude MnP rich extracts indicated that a significant decrease in the percentage value of lignin and increase in in-vitro digestibility matter (at confidence interval 95%) when compared with untreated straws.
通过PB试验设计，筛选了阴蒂霉(Clitopilus scyphoides)深层发酵产木质素降解酶MnP的培养基组分，考察了各组分的主要作用及其对MnP产量的贡献率。本研究在温度30℃，孵育5天的条件下，共考虑了31种成分，其中半乳糖、麦芽提取物、KH2 PO4、NH4 H2 PO4、CaCO3、Tween80、酒石酸和乙酸钠是MnP生产的重要成分。进一步，利用响应面法对所筛选组分的培养基、温度、pH和孵育天数进行优化。优化后的培养基含1.5%半乳糖、0.06%麦芽提取物、0.02%KH2 PO4、0.15%NH4 H2 PO4、0.003%CaCO3、0.8%Tween80、0.005% MnSO4、0.88%酒石酸和3%醋酸钠，在温度31℃、pH 5.2条件下培养5 d, MnP产率(43.2±1.29 U mL-1)是未优化培养基(1.1±0.087 U mL-1)的43倍。试验了所生产的MnP对不同作物残茬的木质素分解作用。对不同作物秸秆进行的消化率研究表明，与未处理秸秆相比，木质素百分比值显著降低，体外消化率显著提高(置信区间为95%)。

This paper deals with a clinical case in a HF cow with signs of ketosis, along with owner history, clinical symptoms and laboratory findings. Milk, urine and blood sample were collected for proper diagnosis of disease. Detection of ketone bodies in urine with Rothera’s test was carried out. Therapeutic regimen was administered as per varied physiological conditions. Such medications as dextrose, steroids, vitamin B complex parenterally (all injected), along with oral gluconeogenic precursors and jaggery were administered. The case was treated successfully, with an excellent recovery.

Effect of partial replacement of maize with dried cereal origin solid food wastes (DCOSFWs) on feed intake, growth and carcass traits of Cobb500 broilers was determined in Hawassa, southern nation nationality and people regional state (SNNPRS), Ethiopia. From 3 sample kebeles, 376 households (Philadelphia=126, Gudumalle=115 and Hetteta=135) were selected through multistage random sampling technique to collect DCOSFW. One hundred sixty five Cobb500 broilers were randomly assigned to five treatment diets with three replications in a completely randomized design. Experimental diets: Grower diets: [T0=0% DCOSFWs (control diet), T1=11.43% DCOSFWs, T2=22.86% DCOSFWs, T3=34.29% DCOSFWs and T4=45.71% DCOSFWs]; Finisher diets: [T0=0% DCOSFWs (control diet), T1=10% DCOSFWs, T2=20% DCOSFWs, T3=30% DCOSFWs and T4=40% DCOSFWs]. Data collection of the feeding trial started after an adaptation period of the chicks to the experimental pens and diets for two weeks. The DM, CP, CF, EE and ME intakes of broilers were similar (p<0.05) across treatment diets. However, CP, CF, EE and ME intake of finisher broilers fed on T4 were higher (p<0.05) than those fed on T0 (control). Body weight gain, average daily gain, slaughter weight, carcass weight, thigh, drumstick, back, thorax and total edible weights of broilers fed on T4 were higher (p<0.05) compared to chicks on T0. Cost of feed per kg body weight gain declined but body weight and net profit increased with increasing level of DCOSFWs. Thus, it is concluded that incorporating DCOSFWs in grower and finisher broilers diet up to 46% is economically feasible and more profitable and nutritionally adequate without adverse effect on the performance of broilers.
