The study was conducted to investigate the effect of α-tocopherol acetate and zinc on body condition, energy metabolites and milk production in Karan Fries cows. Sixteen pregnant Karan Fries cows were selected two months before expected date of calving. The experimental animals were randomly divided in to two groups namely control group (eight cows) and treatment group (eight cows). Treatment group cows were supplemented with α-tocopherol acetate @ 1000 IU/day/cow and zinc @ 60 ppm/day/cow. Blood samples were collected on the days -60, -45, -30, -15, -7, 0, +7, +15, +30, +45 and +60 with respect to expected date of calving. The body weight and body condition score of all the experimental animals was recorded on the day of blood collection. After calving milk yield of the experimental animals was recorded till 60 days in milk. At parturition, body weight and body condition score differ significantly (P<0.001) in treatment group than control group (448.00 vs. 416.33 Kg and 4.42 vs. 4.17, respectively). The overall mean (±SEM) of plasma glucose was found to be significantly (P<0.001) higher in treatment group as compared to control group (62.39±1.23 vs. 57.44±1.59 mg/dl). The overall mean of non-esterified fatty acids was found to be significantly (P<0.001) lower in treatment group as compared to control group (197.10±3.38 vs. 239.21±3.48 μM/L). The overall mean of milk yield was found significantly (P<0.001) higher in treatment group as compared to control group (20.48±1.16 vs. 16.94±1.38 Kg/day i.e. 20.90%). The results of this study indicated that supplementation of antioxidants like α-tocopherol acetate and zinc have beneficial effects on milk production along with improved body condition and metabolic status of the animals.

The use of shearing during pregnancy has been described as a tool for improving productivity in sheep and for minimizing perinatal mortality in lambs through the increase of fetal development. This study assessed the effect of shearing around 74 days of gestation on the productive performance of ewes and lambs during the first month of life. Forty Corriedale ewes were inseminated in autumn in Southern Brazil. All ewes were kept together at the same pasture under extensive husbandry conditions. The ewes were randomly separated into two treatment groups: twenty animals were completely sheared at 74 ± 6 days of pregnancy, and twenty were kept without sheared during pregnancy, composing the control group. Ewes and their lambs were evaluated at three different times during the experiment: at birth, between 15 and 21 days post-partum and between 22 and 45 days post-partum. Ewes had their body condition score, body weight, placental weight, milk production and serum concentrations of beta-hydroxybutyrate measured, while lambs had hematocrit, hemoglobin, and plasma lactate and glucose, as well as body weight at birth and until wean determined. Values of hematocrit and hemoglobin were lower and body weight at birth and at wean was higher in the group of lambs born from sheared ewes. Placenta weight was higher in sheared ewes. Body condition score and beta-hydroxybutyrate showed no differences between groups. Milk production of sheared ewes (1.26 L/day) was higher than in control group (0.93 L/day). Shearing ewes at 74 days of pregnancy was efficient for the better development of lambs at post-birth, reducing perinatal mortality rates.

Abstract The objective of this study was to evaluate the milk production, body weight, and body condition score (BCS) of ewes fed with different energy levels. Seventy-one ewes were used and distributed in three treatments according to the metabolizable energy (ME, Mcal/kg) levels in the diet: CTL = according to the NRC (2007) recommendation for each stage (gestation and lactation); PLUS = CTL plus 10% of ME per kilogram of dry matter; LESS = CTL less 10% ME per kilogram of dry matter. Body weight and body condition score were evaluated a week before the expected date of parturition, a week after giving birth, and at weaning (60 days). Dairy production was evaluated at 20, 30, 40, 50 and 60 days after giving birth by the indirect method of the two weighing. The experimental design was analyzed as randomized complete blocks. There were no differences on milk production during almost all the lactation curve. Only on day 50 (P = 0.051), CTL was still at peak, while LESS and PLUS had already decreased their production. However, at 60 days, all treatments were already with low production, justifying weaning in this period. Results of weight and BCS showed a significant difference in all periods evaluates. Ewes in the PLUS diet had greater BW and BCS. The BCS before giving birth is expected to be over 3.5 and treatment LESS was the only one that did not achieve this score (2.66, 3.37, 3.83 for LESS, CTL, and PLUS, respectively). At weaning, ewes fed PLUS and CTL had BCS of 3.51 and 2.92, respectively, but treatment LESS had only 1.82. That is prejudicial for the next mating seasonal and this animal. We concluded that LESS diet interfered with the body reserves of sheep.

Body Concentration

Body condition of lactating dairy cows varies at different stages of lactation. Cows usually mobilise their body reserves to provide energy and protein for milk production in early lactation, and gain weight to deposit energy and protein for pregnancy at a later stage. The objective of the present study was to examine relationships between body condition score (CS) and body concentration of lipid, CP and energy.

The Australian dairy sheep industry is small and mostly based on a natural grass grazing system which can limit productivity. The current study tested different plant oil-infused and rumen protected polyunsaturated fats and their interactions with sire breeds to improve lactation traits and body condition score (BCS) of ewes grazing low quality pastures. It was hypothesised that supplementing lactating ewe diets plant-derived polyunsaturated oils will improve milk production and composition without compromising BCS. Sixty ewes (n=10/treatment) in mid-lactation, balanced by sire breed, parity, milk yield, body condition score, and liveweight were supplemented with: 1) control: wheat-based pellets without oil inclusion; wheat-based pellets including 2) canola oil (CO); 3) rice bran oil (RBO); 4) flaxseed oil (FSO), 5); safflower oil (SFO) and 6) rumen protected fat containing eicosapentaenoic acid and docosahexaenoic acid (RPO).&nbsp; Except for the control group, all supplementary diets included the same level of 50 ml/kg DM of oil and all diets were isocaloric and isonitrogenous. Experimental animals were grazed in the same paddock with ad libitum access to pasture, hay and water during the 10-week study. RPO was the most effective diet that enhanced milk, fat and protein yields by approximately 30, 13, and 31% respectively (P&lt;0.0001). Significant increase in milk production was also observed in CO, RBO, and SFO (P&lt;0.0001). Breed significantly influenced animal performance with higher milk yield recorded for crossbred Awassi x East Friesian (AW x EF) (578 g/day) vs purebred Awassi (452 g/day) (P&lt;0.0001). This study provides empirical evidence for the use of rumen-protected and plant-derived oil-infused pellets as supplements under low quality pasture grazing conditions, to improve production performance of purebred Awassi and crossbred AW x EF ewes.

The objective of the investigations presented in this work was to establish the effects of a glycerol-based energy supplement in the diet of high-yield dairy cows on their body condition and production results during the early stage of lactation. Forty-seven cows were selected before calving, and they were divided into two groups: controls (n=26) and experimental (n=21). Cows of the experimental group were administered the preparation 'Energy Top' (Biochem GMBH, Germany), in a quantity of 250 ml daily during the final two weeks of the dry period and until the 60th day of lactation. The body condition score (BCS) of all cows was determined 10 days before calving, and on days 15 and 60 after calving. Blood samples were taken 10 days before and 15 days after calving, and concentrations of glucose and beta hydroxi-butyric acid (BHBA) were determined in all samples. Average daily milk production of all cows was measured on days 30 and 60 of lactation. The results showed that the differences in BCS between the dry period and puerperium, or the dry period and the 60th day of lactation, were within physiological values in the experimental group of cows, and higher than physiological values in the control group. Glucose concentration was statistically significantly higher in the experimental group than in the control group of cows 10 days before calving (p<0.05) and 15 days after calving (p<0.01). Fifteen days after calving, the BHBA concentration in the control group of cows was significantly higher (p<0.01) than in the experimental group. On days 30 and 60 of lactation, the milk yield of experimental cows was higher than of those in the control group, but the difference was not statistically significant. The obtained results indicate that energy supplements should be used as an integral part of the feed ration during the peripartal period in order to prevent changes in the body condition score of cows by more than 0.7 points, and also that, in cows with a daily milk production of up to 30 l, an energy supplement has a stimulatory effect on milk production until the establishing of an energy balance, in this case, until around the 30th day following calving. .
