The current study aimed to evaluate the effects of betaine on the growth performance, blood parameters, and histopathology of growing lambs offered fresh or saline water. A total of 20 healthy Ossimi male lambs, aged 9 months, were randomly assigned to four treatments (n=5). Lambs received NaCI (0% or 1.5%) with drinking water and betaine (0 or 2500 mg/kg diet) with ration. The experiment lasted 135 days. Saline water significantly decreased (p<0.01) lamb body weight, blood urea, sodium and alanine amino transferase. Betaine significantly increased (p<0.05) lamb body weight, Hb concentration, RBCs count and hematocrit value. However, betaine decreased (p<0.05) blood neutrophils, band cells and eosinophils, urea, and both alanine and aspartate amino transferases. Saline water induced swelling and disarrangement of hepatocytes, focal medullary tubular necrosis and calcium calculi in renal tissue, and fasciculation and focal lysis of cardiac muscle fibers. In contrast, betaine ameliorated these harmful effects of saline water. In conclusion, dietary betaine could enhance the growth performance and ameliorate the harmful effects of drinking saline water for sheep.
本研究旨在评价甜菜碱对生长羔羊的生长性能、血液参数和组织病理学的影响。选取20只9月龄健康的奥西米公羔羊,随机分为4组(n=5)。羔羊按日粮添加nacl(0%或1.5%)和甜菜碱(0或2500 mg/kg日粮)。试验期135 d。盐水显著降低了羔羊体重和血尿素、钠和丙氨酸氨基转移酶(p<0.01)。甜菜碱显著提高了羔羊体重、血红蛋白浓度、红细胞计数和红细胞压积值(p<0.05)。然而,甜菜碱降低了血液中性粒细胞、带状细胞和嗜酸性粒细胞、尿素以及丙氨酸和天冬氨酸氨基转移酶(p<0.05)。盐水引起肝细胞肿胀和紊乱,肾组织局灶性髓小管坏死和钙质结石,心肌纤维束状和局灶性溶解。相比之下,甜菜碱改善了盐水的这些有害影响。综上所述,饲粮中添加甜菜碱可以提高绵羊的生长性能,改善饮用盐水的有害影响。

This investigation is an endeavor to prevent or limit the negative effects resulted of ingesting diets contaminated with a combination of aflatoxin B1 (AFB1) and ochratoxin A (OTA). This experiment aimed to evaluate the efficacy of supplementing diets with organic, inorganic and/or mixed toxin binders, throughout a feeding and digestibility trials, to relieve mycotoxins' negative effect towards maintaining the productive and reproductive performance of Ossimi ewes and their offspring. One hundred Ossimi ewes averaged 38.97 ± 0.55 kg body weight and aged 3 to 4 years were chosen, 30 days before the expected lambing date and divided randomly into five equal groups (20 each). The first group received an uncontaminated diet and served as a negative control (NC). The second group fed a diet contaminated with AFB1 mixed with OTA and served as a positive control (PC), while the third group fed contaminated diets and supplemented with organic toxin binder (OB). The fourth group fed contaminated diet supplemented with inorganic toxin binder (IOB) and the fifth group fed contaminated diet and supplemented with a mixture of OB and IOB (OB+IOB).The results showed that PC group had decrease in levels of digestibility coefficients, feeding values, milk production, feed intake, serum total protein, albumin, glucose and cholesterol while had increase of ALT, AST and urea concentrations. The decrease of ewes’ body weight was associated with increased age at 1st estrous post-lambing versus decreasing the fertility parameters of the PC group. Besides, there was a decrease in thyroid hormones and antioxidant activities versus the increase in malondialdehyde concentrations. In the same group, changes in ewes’ body weight decreased, while the feed conversion ratio increased with the PC group compared to the NC control group. Whereas, all treatments tested in the current study could reverse the mycotoxin-induced effects significantly and restore the normal levels of animals. In conclusion, IOB alone, or the mixture of OB+IOB, can be added to ewes’ diets for the relief of symptoms induced by mycotoxin.
本研究旨在预防或限制摄入黄曲霉毒素B1 (AFB1)和赭曲霉毒素a (OTA)联合污染的饮食所产生的负面影响。本试验旨在通过饲喂和消化率试验,评估在饲粮中添加有机、无机和/或混合毒素粘合剂,以减轻真菌毒素对维持奥西米母羊及其后代生产和繁殖性能的负面影响。选取3 ~ 4岁、平均体重38.97±0.55 kg的奥西米母羊100只,在预产日前30 d随机分为5组,每组20只。第一组给予不受污染的饮食,作为阴性对照(NC)。第二组饲喂AFB1污染饲粮并添加OTA作为阳性对照(PC),第三组饲喂AFB1污染饲粮并添加有机毒素结合剂(OB)。第4组饲喂在污染饲粮中添加无机毒素黏合剂(IOB)的试验饲粮,第5组饲喂在污染饲粮中添加无机毒素黏合剂(OB+IOB)的试验饲粮。结果表明:PC组消化率系数、饲用值、产奶量、采食量、血清总蛋白、白蛋白、葡萄糖和胆固醇水平均降低,ALT、AST和尿素浓度升高。母羊体重的下降与产羔后第一次发情年龄的增加有关,与PC组生育参数的降低有关。此外,甲状腺激素和抗氧化活性随丙二醛浓度的增加而降低。在同一组中,与NC对照组相比,PC组母羊体重变化幅度减小,饲料系数升高。然而,在本研究中测试的所有治疗方法都可以显著逆转真菌毒素诱导的效应,并恢复动物的正常水平。综上所述,在母羊日粮中单独添加或添加OB+IOB均可缓解霉菌毒素引起的症状。

The purpose of this study was to evaluate the effect of dietary betaine supplementation on growth characteristics and some blood constituents of Ossimi rams. A total of 18 Ossimi rams were randomly divided into three equal groups, considering their body weight. Animals of the first group (Co) served as control, while animals of the second (BET1) and third (BET2) groups offered 2 and 4 g of betaine/head/day, respectively. At the last day of the experiment, blood samples were taken to estimate some blood metabolites. Three digestibility experiments were carried out to determine nutrients digestibility and nutritive values of the rations. Body weight was recorded while average daily gain, feed conversion and feed economic efficiency were calculated. The results show that betaine supplementation to rams either with 2 or 4 g/head/day increased (P≤0.05) plasma total protein, plasma globulin, plasma glucose and triiodothyronine hormone (T3), while it significantly (P≤0.05) decreased A/G ratio and plasma total cholesterol. Concentrations of plasma albumin and plasma urea N did not differ significantly due to betaine supplementation. Digestibility coefficients of DM, OM, CP, EE and CF were significantly (P≤0.05) increased for BET2 group than for BET1 and Co groups. However, NFE digestibility was not influenced by betaine. The TDN value was increased (P≤0.05) for BET2 diet compared with other treated diets. While, the nutritive values as DCP did not significantly differ among treatments. Animals in BET1 and BET2 consumed more (P≤0.05) metabolizable energy (ME, Mcal/kg) compared with the control group. Live body weight did not differ (P>0.05) among groups while average daily gain and total weight gain were improved (P≤0.05) in treated groups. Feeding Ossimi rams on BET1 increased significantly (P≤0.05) daily dry mater intake (DMI), and total digestible nutrient intake (TDNI) when compared with BET2 and Co groups, while treated groups consumed (P≤0.05) metabolizable energy (ME) more than the control group. Daily digestible crude protein intake (DCPI) did not significantly differ among treatments. In conclusion, dietary betaine supplementation to Ossimi rams could modify some metabolic processes, and enhance feed consumption and energy mobilization which could be reflected on improving the productive performance.
本研究旨在评价饲粮中添加甜菜碱对羊生长特性及部分血液成分的影响。18只奥西米公羊根据体重随机分为3组。第一组(Co)作为对照,第二组(BET1)和第三组(BET2)分别给予甜菜碱2和4 g /头/天。在实验的最后一天,采集血液样本来估计一些血液代谢物。通过3个消化率试验,测定饲粮的营养物质消化率和营养价值。记录体重,计算平均日增重、饲料系数和饲料经济效益。结果表明,饲粮中添加2或4 g/头/d甜菜碱可显著(P≤0.05)降低A/ g比和血浆总胆固醇,提高血浆总蛋白、血浆球蛋白、血浆葡萄糖和三碘甲状腺原氨酸激素(T3)水平(P≤0.05)。补充甜菜碱对血浆白蛋白和尿素N浓度无显著影响。BET2组DM、OM、CP、EE和CF的消化系数显著(P≤0.05)高于BET1和Co组。甜菜碱对NFE消化率无明显影响。与其他饲粮相比,BET2饲粮的TDN值显著升高(P≤0.05)。而各处理间作为DCP的营养价值无显著差异。与对照组相比,BET1和BET2组动物消耗的代谢能(ME, Mcal/kg)增加(P≤0.05)。各组间活重差异不显著(P>0.05),平均日增重和总增重显著提高(P≤0.05)。饲喂BET1组的奥西米公羊日干物质采食量(DMI)和总可消化营养物质采食量(TDNI)显著高于BET2和Co组(P≤0.05),代谢能(ME)消耗显著高于对照组(P≤0.05)。日可消化粗蛋白质摄入量(DCPI)各组间差异不显著。综上所述,饲粮中添加甜菜碱可以改变黑羊的某些代谢过程,提高饲料消耗和能量动员,从而提高生产性能。

To determine effect of the administration of exogenous melatonin and photoperiod on initiating the lambing season and improving reproductive efficiency of sheep, a total of thirty-four multiparous, non-pregnant Ossimi ewes aged 3-5 years with average body weight 55.94±1.80 kg were used. After weaning and the starting of the breeding season, the ewes were divided into four groups; the 1st group (7 ewes) was exposed to natural daylight (NL) and severed as a control group, the 2nd group (9 ewes) was exposed to 16-hour artificial lighting (AL), the 3rd group (10 ewes) was exposed to natural daylight+18-mg/h melatonin (NL+MEL), while the 4th group (8 ewes) was exposed to 16-hour artificial lighting+18-mg/h melatonin (AL+MEL). The treatment of the ewes continued throughout the mating season and for three consecutive estrus cycles (60 days). Ewes were weighed before mating and after parturition. Reproductive traits were recorded after parturition. Results revealed that exogenous melatonin (induced by either natural daylight or artificial photoperiod) exhibited significantly (P≤0.05) higher body weights (6.20±1.711 and 4.14±1.91kg for NL+MAL and AL+MEL groups more than the control group). Both of the melatonin treatment and the use of artificial light for 16 h insignificantly influenced reproductive parameters (percentages of fertility, conception rate, scanning, lambing rate, and fecundity rate of Ossimi ewes. Fertility and conception rates tended to be higher in (NL+MEL) and (AL+MEL) groups, while SP percentage, lambing and fecundity rates were higher in treated groups than control. The percentage of the number of services per conception (NSC) and abortion rate were insignificantly reduced in treated ewes as compared with the control. Both weaning rate and the survival rate was elevated (P≥0.05) in treated ewes than untreated ones. Lambing interval and days open were significantly lower (P≤0.05) in AL+MEL group than AL and NL+MEL groups. The lambs’ weight at birth, weaning, net gain, and average daily gain tended to be higher in (NL+MET) and (AL+MEL) groups than other groups with insignificant differences. It can be concluded that, stimulation of melatonin (induced by natural daylight and artificial photoperiod manipulation) might be a useful tool in improving reproductive performance and lamb production in Ossimi sheep.
为了研究外源褪黑素和光周期对绵羊产羔季启动和繁殖效率的影响,本试验选用34只3 ~ 5岁、平均体重55.94±1.80 kg的多胎、未妊娠的奥西米母羊。在断奶和繁殖季节开始后,将母羊分为四组;第一组(7只母羊)暴露于自然光(NL)下作为对照组,第二组(9只母羊)暴露于16小时人工照明(AL)下,第三组(10只母羊)暴露于自然光+ 18mg /h褪黑激素(NL+MEL)下,第四组(8只母羊)暴露于16小时人工照明+ 18mg /h褪黑激素(AL+MEL)下。母羊的治疗在整个交配季节和连续三个发情周期(60天)持续进行。母羊在交配前和分娩后称重。分娩后记录生殖性状。结果表明,外源性褪黑素(自然光和人工光周期诱导)显著(P≤0.05)提高了NL+MAL组和AL+MEL组的体质量(分别为6.20±1.711和4.14±1.91kg)。褪黑素处理和人工光照16小时对奥西米母羊的生殖参数(受孕率、受孕率、扫描率、产羔率和繁殖率)均无显著影响。(NL+MEL)和(AL+MEL)处理组的受胎率和受胎率均高于对照组,SP率、产羔率和受胎率均高于对照组。与对照组相比,实验组母羊的每胎服务次数百分比(NSC)和流产率均无显著降低。处理后的母羊断奶率和成活率均高于未处理母羊(P≥0.05)。AL+MEL组产羔间隔和开胎天数显著低于AL和NL+MEL组(P≤0.05)。(NL+MET)和(AL+MEL)组羔羊的出生重、断奶重、净增重和平均日增重有高于其他组的趋势,但差异不显著。由此可见,刺激褪黑素(由自然光和人工光周期操纵诱导)可能是提高奥西米羊繁殖性能和产羔的有效工具。

Semen storage changes sperm synthesis and biochemical characteristics and hence hinders ferti-lizing ability. Mixture of two various sugar molecules appeared an improved positive impact on stored spermatozoa of different species. The current study aimed to investigate the effect of fructose, sucrose and raffinose supplementation to Tris-glucose-egg yolk extender (TGY) beside comparing their effect with the effect of commercial Triladyl® extender on bull’ and ram’ semen stored at 5 °C for 96 hours. The semen samples were pooled, extended and divided into five portions. TGY or Triladyl® extenders were diluted at rate 1 part of raw semen: 5 parts of the extender. The TGY diluent was split into four diluent parts in sterilized test tubes. TGY and Triladyl® extenders contained one type of sugar, while the other three extended semen samples contained two types of sugar including TGY plus 0.990 g fructose (TGYF), 0.700 g sucrose (TGYS) and 0.700 g raffinose (TGYR) /100ml extender. The ex-tended semen was stored at 5°C for 0, 24, 48, 72 and 96 hours. The obtained data show that spermato-zoa parameters significantly (P < 0.01) decreased with increasing preservation period of all diluent samples. Meantime, supplementation with fructose, sucrose or raffinose with TGY extended samples improved significantly (P < 0.01) sperm properties (motility, livability with acrosomal status and normality, enzymatic actions of AST, ALT, LDH, and ALP, and sperm penetration ability for both bull and ram diluted semen.

However, as these results depend on in vitro assessments, there is a need for further fertil-ity trials to confirm it.
精液的储存改变了精子的合成和生化特性,从而阻碍了受精能力。两种不同糖分子的混合物对不同物种的精子有更好的积极影响。本研究旨在探讨添加果糖、蔗糖和棉子糖对Tris-glucose-egg -蛋黄膨化剂(TGY)的影响,并将其与市售Triladyl®膨化剂对5°C保存96小时的公牛和公羊精液的影响进行比较。精液样本被收集、扩展并分成五部分。TGY或Triladyl®填充剂按1份生精液:5份填充剂的比例稀释。TGY稀释剂在无菌试管中被分成四个稀释剂部分。TGY和Triladyl®扩展剂含有一种糖,而其他三个扩展精液样品含有两种糖,包括TGY加0.990 g果糖(TGYF), 0.700 g蔗糖(TGYS)和0.700 g棉子糖(TGYR) /100ml扩展剂。延长后的精液在5℃下分别保存0、24、48、72和96小时。结果表明,各稀释液样品的精子参数随保存时间的延长而显著降低(P < 0.01)。同时,在TGY扩展样品中添加果糖、蔗糖或棉子糖显著提高了公牛和公羊稀释后精液的精子性能(活动力、顶体状态和正常状态下的存活率、AST、ALT、LDH和ALP的酶活性以及精子穿透能力)(P < 0.01)。对于公牛和公羊的稀释精液,商用Triladyl®exten- er的精子特性均优于未添加任何添加剂的TGY。综上所述,本研究结果表明,使用含糖混合物的稀释剂可以获得合理且有利的公牛和公羊精子保存效果。然而,由于这些结果依赖于体外评估,因此需要进一步的生育试验来证实它。

SummaryA five-months experiment was carried out to investigate the effect of partial replacement of rice straw in the ration of goat kids by Moringa oleifera (MO) forage on feed intake, digestibility, rumen fermentation, some blood parameters and productive performance of growing goat kids. Twenty-one growing Baladi goat kids averaged six months age and 11.20 kg live body weight (LBW) were divided into three similar groups and randomly assigned to the following dietary treatments; control group (R1) which fed 60% CFM + 40% RS, while group (R2) fed 60% CFM + 20% RS + 20% MO and R3 fed 50% CFM + 25% RS + 25% MO. The daily feed allowance of goat kids was calculated according to NRC (2007) and adjusted biweekly. The experimental rations offered twice a day at 8 am and 2 pm in equal portions up to the end of the experimental period. Body weight, feed intake and feed conversion were determined over the whole trial. At the end of the feeding trial, three digestibility trials were conducted on twelve goat kids. Results indicated that the digestibility of most nutrients of the two tested rations were significantly higher than those of control one. The highest values were recorded with 20% MO-ration (R2). The feeding values as TDN and DCP followed a similar trend to those of nutrients digestibility among dietary treatments. Growth performance in respect of final weight, total weight gain, daily gain and feed conversion efficiency were significantly superior with kids fed R2 and R3 rations compared with control ration (R1). The best values occurred with R2. Also, kids fed 20 or 25% MO-rations had significantly higher return and economic efficiency than those fed control ration (R1). Rumen function parameters and blood metabolites profile have been also investigated throughout this study.Accordingly, we could recommend for feeding the growing goat kids, supplementing ration with Moringa oleifera forage especially those containing poor quality roughage like rice straw, since it improve daily gain, digestibility. feed efficiency, and economic efficiency. The recommended replacement rate with Moringa is for 20 or 25% of rice straw.
摘要本试验旨在研究辣木(MO)饲料部分替代山羊日粮中稻草对生长山羊采食量、消化率、瘤胃发酵、部分血液指标及生产性能的影响。选取21只平均6月龄、11.20 kg活体重的生长中的巴拉迪山羊,随机分为3组,分别采用以下饲粮处理:对照组(R1)饲喂60% CFM + 40% RS, R2组(R2)饲喂60% CFM + 20% RS + 20% MO, R3组(R2)饲喂50% CFM + 25% RS + 25% MO。山羊日采食量按NRC(2007)计算,每两周调整一次。试验口粮每天2次,分别于上午8点和下午2点等量提供,直至试验结束。在整个试验期间测定体重、采食量和饲料系数。饲喂试验结束时,对12只山羊进行3项消化率试验。结果表明,两种试验饲料的大部分营养物质消化率均显著高于对照饲料。当mo含量为20%时(R2)最高。各饲粮处理的TDN和DCP摄食值与营养物质消化率的变化趋势相似。R2和R3日粮在末重、总增重、日增重和饲料转化效率方面的生长性能均显著优于对照日粮(R1)。R2的值最好。饲粮中添加20%或25% mo的儿童的收益和经济效益显著高于对照日粮(R1)。本研究还对瘤胃功能参数和血液代谢物谱进行了研究。因此,在生长山羊的饲粮中,建议在饲粮中添加辣木饲料,特别是含有劣质粗饲料如稻草的辣木饲料,可提高日增重和消化率。饲料效率,经济效益。建议用辣木代替20%或25%的稻草。

ABSTRACTGoat production is an integral part of farming systems in Indonesia and can play an important role in improving livelihood and food security in rural households. This study aimed to assess the economic performance of goat production in Malang regency, East Java Province of Indonesia. Data were collected from a total of 42 farmers using a survey based on structured questionnaire. Indicators for the economic performance of goat production were profit (P), breakeven point (BEP), margin of safety (MOS) and revenue -cost ratio ((R/C ratio). Farmers were classified into three strata, stratum-1 (0.6-1.0 AU, n=15), stratum-2 (1.1-1.5 AU, n=14), and stratum-3 (1.6 -2.1 AU, n=13). Data included primary information (i.e. production cost, revenue) that obtained by survey method using structured questionnaire, whereas the related institution has supplied secondary data. Descriptive technique with applying economic formulation namely, profit, BEP, MOS and R/C ratio were employed to analyze the data. Results show that feed (concentrate and forage) cost shared the highest costs (expenses ranged from 59.36% to 71.15 %.) of the total production costs. Total variable costs per animal unit were lowest (69.57%) in stratum-1 than those in stratum-3 (80.51%) and stratum-2 (80.79%). Stratum-1 therefore, consider as the best BEP of IDR 346, 694/AU during one month period. The monthly revenue per Animal Unit of stratum-2 (IDR 1,038,945) was slightly different compared to sratum-3 (IDR 978,884), with the lowest one (IDR 824,765) come from stratum-1. Hence, stratum-3 ECB for goat enterprise represented as the best feasible farming with monthly profit of IDR 613,768/AU. Likewise, this farming also executed an efficient enterprise on the basis of 62.64% of MOS and 2.68 of R/C ratio. Overall, high feed cost was the major problem that affected goat economic production. Therefore, improvement of feed use efficiency is recommended.
山羊生产是印度尼西亚农业系统的重要组成部分,可以在改善农村家庭的生计和粮食安全方面发挥重要作用。本研究旨在评估印度尼西亚东爪哇省玛琅县山羊生产的经济效益。采用基于结构化问卷的调查方式,对42名农户进行数据收集。山羊生产经济效益的指标为利润(P)、盈亏平衡点(BEP)、安全边际(MOS)和收益成本比(R/C)。将农民分为3层:1层(0.6 ~ 1.0 AU, n=15)、2层(1.1 ~ 1.5 AU, n=14)、3层(1.6 ~ 2.1 AU, n=13)。数据包括主要信息(即生产成本,收入),通过结构化问卷调查法获得,而相关机构提供了次要数据。采用经济公式的描述技术,即利润、BEP、MOS和R/C比率对数据进行分析。结果表明,饲料(精料和草料)成本占总生产成本的比例最高,为59.36% ~ 71.15%。每头动物单位总可变成本1层(69.57%)最低,3层(80.51%)和2层(80.79%)最低。因此,考虑层1在一个月期间的最佳BEP为346,694 IDR /AU。层2的每动物单位月收入(1,038,945印尼盾)与层3(978,884印尼盾)略有不同,最低的是层1(824,765印尼盾)。因此,对于山羊企业来说,层3 ECB是最可行的养殖方式,月利润为613,768印尼盾/AU。同样,该养殖场在MOS为62.64%、R/C为2.68的基础上,也是一个高效的企业。总体而言,饲料成本高是影响山羊经济生产的主要问题。因此,建议提高饲料利用效率。

SUMMARYSheep are a valuable livestock species because of their ability to convert forages, as well as feedstuffs not suitable for human consumption, into meat and milk that are important sources of human dietary protein. Sheep are the most abundant ruminant livestock species in Egypt, and great opportunity exists to enhance their productivity though implementation of a genetic improvement program utilizing the advanced reproductive technologies of artificial insemination and embryo transfer. These two reproductive technologies permit the production of more offspring from genetically superior animals in a shorter amount of time than would be possible through conventional breeding. It will be important to match the appropriate breeds of sheep with the proper nutritional and production environments that will enable animals to express their full genetic potential for enhanced production of meat, milk and fiber.
绵羊是一种有价值的家畜,因为它们有能力将不适合人类食用的牧草和饲料转化为肉和奶,而肉和奶是人类膳食蛋白质的重要来源。绵羊是埃及最丰富的反刍家畜物种,通过利用人工授精和胚胎移植等先进生殖技术实施遗传改良计划,存在着提高其生产力的巨大机会。这两种生殖技术使得基因优越的动物在较短的时间内比传统育种产生更多的后代成为可能。重要的是将适当的绵羊品种与适当的营养和生产环境相匹配,使动物能够充分发挥其遗传潜力,以提高肉、奶和纤维的产量。

SUMMARYThe current study was conducted to evaluate 383 Sohagi sheep in Sohag governorate, Egypt using a multivariate approach. Data were divided into two age groups of 294 young animals less than 10 months old (147 for each sex) and 89 adults animals from 10 months old and above (9 males and 80 females). Body weight (BW) and four body measurements (heart girth (HG), height at withers (HW), height at rump (HR) and body length (BL)) were measured through the period 2017 and 2018. In young and adult sheep, two factors (principal components) were extracted and accounted for 89.2% and 57.8% of the total variance, respectively. The first factor explained 46.4% and 30.6% of the total variance and the higher positive loading was observed for HW, RH and BL in young sheep whereas the higher positive loading was for HW and RH in adult sheep. The second factor accounted for 42.8% and 27.2% of the total variance and the higher positive loading was obtained for BW and HG in young sheep while was influenced by BW, HG and BL in adult sheep. The use of principal components was more proper than the use of original associated traits to explain body measurements in this study. Thus, extracted factors could be useful in breeding programs with enough decrease in the number of measurements traits to be registered to interpret the body conformation. Also, these principal components could be used as factor scores to predict body weight of Sohagi sheep.
本研究采用多变量方法对埃及Sohag省的383只Sohagi羊进行了评估。数据被分为两个年龄组,10月龄以下的幼畜294只(雌雄各147只),10月龄及以上的成年动物89只(雄性9只,雌性80只)。在2017年和2018年期间测量体重(BW)和四项身体测量(心围(HG)、马肩高(HW)、臀高(HR)和体长(BL))。在幼羊和成年羊中,提取了两个因子(主成分),分别占总方差的89.2%和57.8%。第一个因子解释了总变异的46.4%和30.6%,幼羊的HW、RH和BL阳性负荷较高,而成年羊的HW和RH阳性负荷较高。第二个因子分别占总方差的42.8%和27.2%,幼羊的体重和汞含量较高,而成年羊则受体重、汞含量和体重的影响。在本研究中,使用主成分比使用原始相关性状更适合解释身体测量。因此,提取的因子可以在育种计划中使用,以减少测量特征的数量,以记录来解释身体构象。这些主成分均可作为预测苏哈吉羊体重的因子得分。
