25 Background: In order to accurately determine the performance of cows in terms of milk yield 26 and milk components, it is necessary to determine the extent and direction of environmental 27 factors. Although many studies have explored environmental factors affecting milk yield, there 28 is not enough information about the effects and direction of environmental factors on the 29 composition of milk. Objective: To determine the effects of non-genetic factors, such as 30 calving season, lactation number, lactation stage, animal age, and herd size on milk yield, the 31 chemical composition of raw milk, and Somatic Cell Count (SCC) in Holstein-Friesian cows. 32 Methods: Data were obtained from 15,354 raw milk samples of 5,118 Holstein-Friesian cows 33 at 276 dairy farms in Türkiye. The data analysis was performed using the General Linear Model 34 (GLM) feature of the SPSS statistics program. Results: Mean fat (F), protein (P), dry matter 35 (DM), lactose (L), urea (U), and Log 10 SCC values of cow milk were 3.74 ± 0.01, 3.19 ± 0.01, 36 11.36 ± 0.03, 4.32 ± 0.01%, 21.57 ± 0.28 mg/dL, and 5.244 ± 0.01 cells/mL, respectively. Peak 37 milk yield (PMY), lactation milk yield (LMY), 305-day milk yield (305-d MY), and SCC 38 values were found to be 33.7 ± 0.13, 8,538.33 ± 89.64 kg, 6,479.42 ± 168.96 kg, and 224,164.34 39 ± 4,402.79 cells/mL, respectively. Conclusion: It is recommended to take measures to improve 40 the protein, dry matter, and urea component of milk in dairy farms in Türkiye and investigate 41 in detail the relationship between raw milk urea component, subclinical mastitis, and 42 reproductive features.

26 Background: Generally, forages used in cow-calf and backgrounding operations have low 27 crude protein and high fiber concentration, limiting animal performance and increasing 28 greenhouse gas emissions. Chlorella spp., a green micro-algae, shows promising attributes 29 to provide nutrients, especially nitrogen, in low-protein diets. However, information is 30 limited regarding the effects of Chlorella spp. on in vitro fermentation and methane (CH 4 ) 31 production. Objective: To evaluate the effects of increasing inclusion levels of algae 32 ( Chlorella spp.) on ruminal in vitro fermentation profile and CH 4 production in a corn silage-33 based diet. Methods: Incubations were conducted on three separate days using corn silage 34 and gin trash as substrate (70:30 ratio, respectively). Treatments were control (without algae), 35 and 1, 5, and 10% of algae inclusion in the substrate replacing basal diet. Ruminal fluid was 36 collected from two ruminally cannulated Angus crossbred steers fed ad libitum a corn silage 37 and gin trash diet. The final pH, the concentration of volatile fatty acids (VFA) and ammonia 38 nitrogen (NH 3 -N), in vitro organic matter digestibility (IVOMD), total gas, and CH 4 39 production were determined after 24 h of incubation. Variables were evaluated using the 40 MIXED procedure of software SAS, and means were compared using orthogonal polynomial 41 contrast. Results: Algae inclusion linearly increased (p<0.01) the IVOMD. However, the 42 final pH and concentration of VFA and NH 3 -N were not different (p>0.05) among the algae 43 levels. The molar proportion of VFA and the acetate:propionate ratio were not affected 44 (p>0.05) by increasing algae inclusion. Finally, total gas and CH 4 production were not 45 different (p>0.05) among treatments. Conclusions: The inclusion of Chlorella spp. did not

32 Backgroud: Ivermectin may changes the levels of cytokines and immunoglobulins in sheep, 33 considering that avermectins affect the immune system. Objective: To determine the effect of 34 ivermectin on the cytokines and immunoglobulins in sheep. Methods: After administration of 35 ivermectin to 10 healthy sheep, sheep-specific interferon-α, tumor necrosis factor-α, interleukin-36 2, interleukin-6, and interleukin-10, immunoglobulin G, immunoglobulin M, and immunoglobulin 37 E levels were measured with ELISA reader. Results: Statistically significant (p<0.05) fluctuations 38 were detected in interkeukin-2 and interkeukin-10 levels. Transient increases (p<0.05) were 39 measured in tumor necrosis factor-α and immunoglobulin E levels (p<0.05). Conclusion: 40 Ivermectin may affect immune system parameters in healthy sheep, however, the effects of 41 ivermectin administration on infected sheep should be investigated.
