Importance: Sheep and goat pox (SGP) virus infection is a highly fatal viral infection of small ruminants that causes major production losses in sheep and goats in Ethiopia while also limiting international trade. Objective: This study aimed to estimate the seroprevalence of SGP infection and assess related risk variables. Methods: A cross-sectional study was conducted from February to August 2023 on 384 serum samples taken from sheep and goats. A serum neutralization test was conducted to detect the presence of antibodies against the SGP virus in Wolaita Sodo Regional Laboratory. Results: The overall seroprevalence rate of SGP was 4.95%. Factors such as sheep (8.26%), female sheep and goats (7.45%), older sheep and goats (8.33%), larger flock size of sheep and goats (10.47%), poorly conditioned sheep and goats (31.58%), sheep and goats with a tick on their skin (10.38%), and animals that had not been vaccinated (5.17%) were found to have higher seroprevalence. Furthermore, the seropositivity in sheep was five times greater than in goats (adjusted odds ratio [AOR], 4.73; 95% confidence interval [CI], 1.39-15.99). Additionally, large-sized flocks of sheep and goats were more likely to be seropositive to pox disease than small-sized flocks (AOR, 6.73; 95% CI, 1.58-28.67). Conclusions and Relevance: Thus, the study revealed the prevalence of SGP in the Wolaita zone. Additional research should be conducted to estimate the extent of the disease at the regional level, and management measures should be implemented to reduce the economic losses associated with this condition.
An in vitro study was carried out to investigate the differences in rumen microbes and fiber degradation capacity between sheep and goats. Three local male sheep and three Inner Mongolia male cashmere goats (aged 1.5 to 2 years; weight 25.0 to 32.0 kg) were each fitted with a permanent rumen cannula used to provide rumen fluid. Cycloheximide was used to eliminate rumen anaerobic fungi. The results showed that the quantities of fungal zoospores in the culture fluid of the control group were significantly greater in the sheep than in the goats; however, bacteria and protozoa counts were significantly higher in goats than in sheep. The digestibility of straw dry matter did not differ significantly between the two species before elimination of fungi, but tended to be higher for sheep (55.4%) than for goats (53.3%). The results also indicated that bacteria counts increased significantly after elimination of anaerobic fungi; however, the digestibility of straw dry matter significantly decreased by 12.1% and 8.6% for sheep and goats respectively. This indicated that the anaerobic fungi of the rumen played an important role in degradation of fiber.
This study investigated the use of multinutrient blocks (MNB) composed of 35% date syrup, 35% date syrup byproducts, 10% date fronds, 7% urea, 7% cement and 6% common salt for growing small ruminants, as partial substitute for the roughage component of the diet (Rhodes grass hay) and its effect on feedlot performance and economics of feeding. Eight growing local Omani goats and 8 sheep (each about one year old) were used in this study. Mean body weights for goats and sheep (kg), respectively were $21.1{\pm}4.5$ and $25.5{\pm}4.1$. The goats and sheep were subdivided into two sub-groups of more or less equal body weights for each species. Each sub-group in both species was either fed on 0.5 kg concentrate+ad libitum Rhodes grass hay or the same diet+restricted hay (about 0.2 kg/head/day) and ad libitum amount of MNB. Sheep significantly (p<0.05) consumed greater amounts of MNB ($36{\pm}17$g/head/day) than goats ($6{\pm}2.5$ g/head/day). Feeding of the MNB was effective in sparing about 40% of the roughage Rhodes grass hay for goats (from 240 to 140 g) and about 42% for sheep (from 252 to 146 g) or approximately 100 g/head/day for both goats and sheep. This reduction (or sparing) in the consumption of Rhodes grass hay was coupled by an improvement in daily liveweight gain (g/head/day) in both goats (from 29 to 46 by 58.6%) and sheep (from 26 to 39 by 50%) and also by an improvement in the feed conversion efficiency (g feed/g gain) of both goats (from 25 to 13.8 by 45%) and sheep (from 28.7 to 17.2 by 40%). Cost of daily consumed feeds as well as cost/kg gain (or cost of meat) were both reduced due to feeding of MNB. They were both respectively reduced by 7.5% (from 53 Baisa/day to 49) and 38% (from 1,828 Baisa/kg to 1,140). It was economically viable to feed MNBs containing date by-products and urea to small ruminants in the Sultanate of Oman.

The effects of animal species and supplements on rumen fluid characteristics, plasma urea-N (PUN) concentration, plasma urea-N pool size, urea-N degradation in the gut and urea-N net flux (urea-N synthesis rate) were studied in goats and sheep, with some minor differences detected. The animals were fed either chopped rice straw ad libitum+200 g soybean meal (SBM), or chopped rice straw ad libitum+190 g soybean meal+300 g sago meal (SBM+SM) for 14 days. The supplements were isonitrogenous (80 g crude protein/animal/d). [$^{14}C$]-urea was used as the marker for urea metabolism studies. Two animals from each species were fed either supplement in a cross-over design in two periods. The results showed that rumen pH was significantly (p<0.001) lower in animals fed SBM+SM than those fed SBM supplement. The ammonia concentrations of rumen fluid were significantly (p<0.01) higher in sheep (382.9 mg N/L) than goats (363.1 mg N/L) when fed SBM supplement but lower (282.5 mg N/L) than that of goats (311.0 mg N/L) when fed SBM+SM supplement. Total VFA concentrations were significantly (p<0.05) higher in animals fed SBM+SM supplement than those fed SBM supplement. Goats had significantly (p<0.01) higher molar proportions of acetate (79.1, 77.7%, respectively) than sheep (75.8, 74.0%, respectively) in both supplements. The molar proportion of acetate was significantly (p<0.05) higher, while that of butyrate lower in animals fed SBM supplement than those fed SBM+SM supplement. In animals fed SBM supplement, the molar proportion of propionate was significantly (p<0.01) higher in sheep (18.0%) than in goats (15.6%), but in animals fed SBM+SM, the molar proportion of butyrate was significantly (p<0.01) higher (9.6%) in sheep than in goats (7.2%). Plasma urea-N concentration, plasma urea-N pool size, urea-N degradation in the gut, urea-N net flux and the fraction of urea-C from the blood entering the rumen were not significantly different between goats and sheep fed either supplement. However, PUN concentration was significantly (p<0.05) lower in animals fed SBM+SM supplement (average of 13.8 mg N/100 ml) than in those fed SBM supplement (average of 16.5 mg N/100 ml). The urea net flux was significantly (p<0.05) higher in goats (average of 14.5 g N/d) than sheep (average of 12.9 g N/d), and animals fed SBM supplement showed higher (average of 14.9 g N/d) urea net flux than animals fed SBM+SM supplement (average of 12.9 g N/d). A significant (p<0.05) positive correlation was observed between urea-N net flux and urea-N degradation; urea-N net flux and pool size; urea-N net flux and urea excretion in the urine; and PUN and rumen ammonia in goats. While in sheep, significant (p<0.05) positive correlation was observed between urea-N net flux and urea excretion in the urine; and PUN and rumen ammonia.
The effect of undecorticated sunflower cake (USFC) as critical protein supplement was assessed and compared with deoiled groundnut cake (DGNC) in adult goats and sheep. The animals were fed a basal diet of wheat straw ad libitum and supplemented with either USFC or DGNC to meet their protein requirement for maintenance. Total dry-matter intake by sheep and goats (g/kg $BW^{0.75}$) on USFC was similar to their counterparts on DGNC supplemented group. However, while intake of cake moiety was significantly (p<0.05) higher in USFC, the intake of wheat straw was significantly (p<0.05) higher by animals on DGNC. Digestibility of various nutrients, except lower crude protein digestibility by goats in USFC group, did not differ significantly between animals given DGNC or USFC. DCP and TDN concentration (% DM) was comparable in sheep and goats irrespective of dietary supplement. Similarly, the intake (g/kg $W^{0.75}$) of DCP, DDM, DOM, and TDN was similar between DGNC and USFC in both sheep and goats. It may be concluded that undecorticated sunflower cake is comparable to deoiled groundnut cake as a critical protein supplement to the roughage based diet of small ruminants.

Objective: This study evaluated the growth, digestibility and rumen fermentation between goats and sheep fed a fattening diet fortified with linseed oil. Methods: Twelve 3 to 4 months old male goats and sheep were randomly allocated into two dietary treatment groups in a $2(species){\times}2$ (oil levels) factorial experiment. The treatments were: i) goats fed basal diet, ii) goats fed oil-supplemented diet, iii) sheep fed basal diet, and iv) sheep fed oil-supplemented diet. Each treatment group consisted of six animals. Animals in the basal diet group were fed with 30% alfalfa hay and 70% concentrates at a rate equivalent to 4% of their body weight. For the oil treatment group, linseed oil was added at 4% level (w:w) to the concentrate portion of the basal diet. Growth performance of the animals was determined fortnightly. Digestibility study was conducted during the final week of the feeding trial before the animals were slaughtered to obtain rumen fluid for rumen fermentation characteristics study. Results: Sheep had higher (p<0.01) average daily weight gain (ADG) and better feed conversion ratio (FCR) than goats. Oil supplementation did not affect rumen fermentation in both species and improved ADG by about 29% and FCR by about 18% in both goats and sheep. The above enhancement is consistent with the higher dry matter and energy digestibility (p<0.05), as well as organic matter and neutral detergent fiber digestibility (p<0.01) in animals fed oil- supplemented diet. Sheep had higher total volatile fatty acid production and acetic acid proportion compared to goat. Conclusion: The findings of this study suggested that sheep performed better than goats when fed a fattening diet and oil supplementation at the inclusion rate of 4% provides a viable option to significantly enhance growth performance and FCR in fattening sheep and goats.
Forty yearling Tswana sheep and goats (20 sheep and 20 goats) of both sexes were used in a feeding trial conducted in Botswana College of Agriculture (B.C.A) Content Farm in Gaborone for three months. The animals were randomized into four treatment groups of five animals per species balancing for weight and sex such that average initial weights were not statistically different. The sheep and goats were individually housed and fed under a common roof. All the animals were fed on Lablab purpureus L. as a protein supplement which was 40% of the ration. In addition to L.purpureus L. the control groups of both species were fed on 60% Cenchrus ciliaris L. as basal diet. The other three treatment groups were fed on different forages namely; sorghum forage (Sorghum sudanense (Piper) Stapf), millet forage (Pearl millet, Pennisetum typhoides (Burm.) Stapf and Hubb.) and veldt grass mainly Urochloa mosambicensis (Hack.) as basal diet (60%). Water was provided individually to all the animals on ad lib. basis. Daily intakes of feed and water were recorded and weighing of the animals was done every two weeks. The collected data were analysed statistically for differences. Average daily weight gain by Tswana sheep was significantly different (p<0.05), sheep fed on millet forage had a higher daily weight gain $(120.24{\pm}8.91g)$ compared with sheep fed on veldt grass $(92.86{\pm}6.94g)$. Treatment effects on daily total DM intake by sheep were significant, the control group (C. ciliaris L.) had higher intake $(705.77{\pm}10.22g)$ and those fed on sorghum forage had the least intake $(668.10{\pm}10.70g)$. There was no significant difference (p>0.05) in the average daily weight gain by Tswana goats and it was 84.52, 73.81, 83.33 and 78.57 g for goats fed on C. ciliaris L., sorghum forage, millet forage and veldt grass respectively. Average daily total DM intake by goats was 655.27, 652.64, 650.07 and 650.94 g for C. ciliaris L., sorghum forage, millet forage and veldt grass respectively. Feed conversion efficiency was 8.00, 8.98, 7.93 and 8.34 for goats fed on C. ciliaris L., sorghum forage, millet forage and veldt grass respectively and were not significantly different (p>0.05).

The 7 sheep microsatellite markersOarFCB48, OarAE101, MAF33, OarFCB11, MAF70, OarFCB304 and OarFCB128, which were located on chromosomes 2, 4, 6, 9, 17 and 19, were selected to PCR in Hu sheep, Tong sheep and their closely related species,the goat. They were studied with the amplifying result of 7 microsatellite sites of Hu Sheep, Tong Sheep and goats, the data of allele number and range of allele' size of amplifying were analyzed with ANOVA. The results showed that there were no significant differences (p<0.05) in microsatellite DNA sites among 3 populations. Concerning the conservation of microsatellites in closely related species, selecting microsatellite sites located on the chromosome where the Robertsonian fusion was caused between sheep and goat, may be used in research into genetic differentiation and evolutionary relationships between sheep and goats.
Twenty growing female Damascus (Shami) goats and twenty growing Chios ewes of two mating ages (10 and 12 months) were used to study the effect of mating age (MA) on reproductive performance (RP). In addition to (RP), The growth, milk production and nutrient requirements were also evaluated. A complete random design in a $2{\times}2$ factorial was used, with (MA) and species as the main factors. (MA) had no effects on (RP), milk production and mortality. No significant difference (p > 0.05) were observed between (MA) or between species, for age at kidding/lambing (K/L). Sheep reached puberty earlier than goats. Average age (months) at conception and at (K/L) was 15.8; 20.8 and l7.0; 22.0 for sheep and goats respectively. Body weight (BW), rather than age was the most important factor determining puberty. Both goats and ewes conceived when they reached about 67% of their mature (BW) for goats and 85% for ewes. Sheep grew faster than goats, but the latter had higher twinning (67.8% versus 25%). Chios sheep were suitable for meat and Shami goats for dairying or dual purpose systems. Nutrient requirements for growth of goats and ewes were similar with an average DM-intake of about 4% (BW); 12-13% CP and 65-69% TDN (DM-basis) of the total ration. It is recommended to breed Chios ewes at a (BW) of at least 50 kg and Shami does at 38 kg, irrespective of their age.
The study was attempted to scrutinize the normal osmotic fragility of erythrocyte in the domestic ruminants, making a comparison with that of human and canine. The animals used in the experiment were apparently healthy adult Holstein cattle, Korean native cattle, sheep (Corriedale) and Korean native goats. Osmotic fragility of erythrocytes was the highest in the Korean native goats, and the next were sheep and Korean native cattle, and Holstein cattle in order. In other words, erythrocytic resistance to osmotic lysis was the strongest in Holstein cattle and the most weak in Korean native goats among the domestic ruminants. In general, resistance of erythrocytes was stronger in human and canine than in the domestic ruminants.
