Livestock plays a significant role in food production, income generation, soil quality, transportation and the overall welfare of communities, especially in developing nations. Sheep and goats are vital sources of food, livelihood and urgent financial needs. Researching livestock practices can help optimize production, enhance productivity, and improve market access, ultimately boosting the economic well-being of developing communities. Research is needed to identify climate-resilient livestock practices, develop drought-resistant breeds, and optimize feed management strategies. By enhancing the resilience of livestock systems, research can help safeguard food security and livelihoods in the face of climate change. Climate change, evidenced by temperature changes and increased extreme weather events, negatively impacts traditional farming systems and livestock production by affecting pastures, feeds, water quality and livestock diseases. Breeds of the Coastal Zone of Western Desert (CZWD)  such as the Barki sheep and goat as well as the Saidi breed in Upper Egypt (UE), have adapted to these harsh conditions and are crucial for smallholders. However, there's an information gap regarding these breeds' productivity in smallholder systems. This study utilizes the Twelve Month Monitoring (12MO) survey to estimate the productivity and demographic parameters of these breeds from 2018 to 2020.

The current study aimed to investigate the effect of microbiological treatment on improving the nutritive value of corn silage as animal feed. Dried whole corn plants were prepared and two ground silos (0.5 ton each) wereused for ensiling whole corn silage and inoculated by bacterial inoculant (containing Lactobacillus plantarum and Entrococcus faecium) at the recommended rate of 1/2g bacterial inoculants/liter of water/ton of fresh whole corn silage. The ensiling period lasted for 50 days. The criteria of response were determined by: the quality of treated corn silage, chemical characteristics and performance of rams, nutrients digestibility and nitrogen balance. Results for treated and untreated silage, respectively, showed that the silage had pH 3.71 and 3.69, Total Volatile Fatty Acids (TVFA) were 2.48 and 1.98 mmol/100ml, and NH3-N values were 6.1% and 6.41% (on dry matter basis). The values of organic matter (OM), crude protein (CP), crude fiber (CF), ether extract (EE), nitrogen free extract (NFE) and ash content on dry matter basis, however, were very close in the two rations. There were no significant differences between the two rations for the dry matter (DM). The value of CF digestibility was not significantly different from that in treated corn silage, while ration contents of treated corn silage were significantly higher in OM, CP, NFE and EE digestibility than the untreated corn silage. Recorded values for total digestible nutrients (TDN) and starch value (SV) of rations of treated corn silage were significantly higher than those of untreated corn silage being 52.64 and 63.37 vs. 43.53 and 56.09%, respectively. The digestible crude protein (DCP) values were (7.43%) for ration of treated corn silage by 5.96% for the ration of untreated corn silage.

This paper focuses on treated date seed with two cellulolytic bacteria (Acetobacter xylinum and Thermonospora fusca) isolated from sheep and evaluated these species by Invitro gas production and metabolism trail.  We evaluated the influence of many rations contain several percentage from date seed untreated and treated on In vitro traild for DM,OM, NDF, ADF, cellulose and hemicellulose disappeara (samples incubated for 24 hrs). the best ration used in metabolism trail . The experimental work was conducted in 2017, at the Department of Animal Production, faculty of agriculture, Ain Shams University, Cairo, Egypt and the experiment of the farm animals occurred in the Animal Production research institute.  Our results in this revealed that the ration content 25% untreated and treated with bacteria  had significant values on NDF, ADF and hemicellulose degradability after 24 hours, especially treatment 2 (Thermonospora fusca) of date seed. In  the experimental ration with ascending level of untreated and treated date seed  had not significant effect on pH value while more effect on total gas production (GP),ammonia, TVFA’s, MP, EMP and  metabolizable energy ME (Mcal/ g). The differences were significant (P<0.05) between control ration and other experimental  rations. Furthermore, ration content date seed treated (R3) had the highest values of DM, OM, CF and EE digestibility. It could be noticed that improving CP, CF and cell wall constituents (NDF, ADF, hemicellulose and cellulose) digestibility may be due to the increasing number of rumen cellulolytic bacteria. In conclusion, the bacterial treatment (Acetobacter xylinum and Thermonospora fusca) with date seed successfully to improve chemical compostion of date seed and Invitro digestiability specially ration contain 25% from total dry matter.  It showed that the strain (Thermonospora fusca) was  the best in In vitro fermentation . Digestibility indicated that ration contain treated date seed (R3) was high DM, OM, ADF and nitrogen than other rations.  It was concluded that treated date seed can replace concentrate in rations and improve In vitro degradability, digestibility trail and no effect on rumen and blood parameters without adversely affecting on helthy animals.

Farm animals have a high economic importance because of their important products such as meat, milk, hair as well as skin, not only in our country but also all over the world. These animals can be infected by serious pathogens, external and internal parasites causing severe damage, which result in losses of animal production. Accordingly, the study of external parasites with light microscope and scanning electron microscope were recorded, to clarify the exact composition of species. Also, differences in the morphological characteristics between the two Myiasis species: Oestrus ovis (Linnaeus, 1758) and Cephalopina titillator (Clark 1797), were investigated.
