This study was conducted to evaluate the effect of dietary supplementation of acetic acid at different levels on milk yield and composition. A total of eighteen Awassi ewes in the early stage of lactation were used in this study, with average body weight (37.631.84) and ages (3–4 years). Animals were allocated to three treatments; the first treatment was control fed with a basal diet without additives (T1). Acetic acid (98%) was added to the concentrate feed daily before feeding by 5 mL/ewe daily in T2 and 10 mL/ewe in T3 after dilution 1:10 with tab water. Results indicate an insignificant increase in ewes' body weight in T2 and T3, which were 40.41 and 41.11 kg compared to T1 at 37.93 kg. Actual milk yield was not affected while fat corrected milk Increased in T3 was 390 g/day compared to T2 with 323 g/day. Milk fat percentage increased (p ≤ 0.05) in T3 at 6.26% as compared to T1 and T2 at 5.65% and 5.43%, respectively, while fat yield was higher (p ≤ 0.05) in T3 at 23.85 g/day than in T2 17.58 g/day. This was reflected in increased milk energy (p ≤ 0.05) in the T3 at 953 kcal/kg compared to T2 at 858 kcal/kg. From the results, it can be concluded that acetic acid can be used as an additive to the ewes diet, and effect positively in ewes’ weight and milk fat.

IMPACT OF ACETIC ACID ON MILK YIELD, COMPOSITION, AND SOME BLOOD PARAMETERS IN AWASSI EWES AT DIFFERENT STAGES OF LACTATION

Journal Journal of Hygienic Engineering and Design

The important thing of the study lies in the inclusion of acetic acid in the diet of the Awassi ewes, which helps increase the fermentation in the rumen, therefore to increase the percentage of fat. Therefore, this study aimed to add different proportions of acetic acid to the diet of ewes and study its effect on milk yield, composition, and some blood parameters. This experiment was conducted between JanuaryMay/2022 at animal field of Technical Agricultural College/ Northern Technical University/ Iraq by using 18 Awassi ewes aged 3 - 4 weeks after birth, with an average body weight of 37.63 ± 1.85 kg. Ewes were distributed into three treatments: first treatment was control fed with experimental diet without additive (T1), ewes in the second (T2) and third (T3) treatment were fed with addition 5 and 10 mL respectively of glacial concentrated acetic acid. The acid was diluted (1 : 10) with tap water, and then mixed with concentrate feed and introduced directly to the ewes. Concentrate diet was consisted from barley grain, wheat bran and soybean meal. Wheat straw was offered by 0.5 kg per ewe daily and in addition to grazed with artificial alfalfa pasture for 2 hr three times a week. Also fresh alfalfa was provided ad libitum. Ewes were weighed biweekly to estimate body weight change during the stages of lactation, and milk fat, protein, solid nonfat, and lactose were measured immediately by using the Lactoscan system. Also, 10 mL of blood samples were collected from jugular vein through each stage of lactation using a plastic syringe, blood samples were centrifuged and glucose, urea, total protein, cholesterol, and triglycerides using (Biolab analysis kit, France) by UV-spectrophotometers were measured. Statistical analysis of the data was performed using SAS software, the general linear model technique is used to do statistical analysis of the data for a complete random design (CRD), and the significant differences between the mean were determined using Duncan’s multiple range tests. In general, results indicated that acetic acid had no effect on milk yield and composition except for fat that increased as acetic acid increased significantly (p ≤ 0.05) in T3 as compared to T1 (5.53, 6.01 and 6.2%), respectively. Although the differences were insignificant, ewes’ weight was higher in the treatments that fed with acetic acid than in control during all stages of lactation. There is trend toward increasing (p ≤ 0.01) blood glucose, while blood cholesterol and triglyceride decreased as acetic acid increased in the feed. The administration of acetic acid at different levels in the concentrate feed of Awassi ewes, affects milk fat which increased with the increase of acetic acid level. This was accompanied by changes in some blood measurements when the glucose concentration increased, while cholesterol and triglycerides decreased with the increase in acetic acid intake. The main effect of acetic acid was noted in the increase of ewes’ weight as compared control.
