Bypass Fat

The present study was planned to cope with feed scarcity issue using bypass fat as a non-conventional feed resource. Twentyfour early lactating indigenous dairy animals comprising of twelve Nili-Ravi buffaloes and twelve Sahiwal cows were selected to determine the effect of bypass fat supplementation on daily milk yield, milk composition and change in body weight. These animals were randomly distributed in to four groups (G0, G1, G2 andG3) having similar parity and milk yield. All the experimental animals were fed with basal ration (Trifolium alexendrinum + wheat straw) and concentrate in equal proportion (3kg day-1 animal-1 ) in addition to 0, 250, 350 and 450g bypass fat animal-1day-1 , respectively. Data collected for each treatment was analyzed under completely randomized design using MINITAB (2000) and the mean was compared using the Tukey’s test (P<0.05). The data revealed a significant effect (P<0.05) on milk production and 3.14 kg day-1 more milk was produced in group G2 compared to control group. Fat corrected milk yield was also enhanced (P<0.05) from 8.25 (G0) to 12.36 kg day-1 (G2). Milk composition in the sense of fat percentage was also improved [5.25 (G0) to 5.78 (G2)] significantly. While average protein content, SNF% and total solids% remained unaffected. Similarly, change in body weight was non-significant. Milk value (Rs./day) was significantly (P<0.05) increased from 512.25 to 747.75 in the group G0 to G2. Form present finding it could be concluded that dietary supplementation of bypass fat in indigenous dairy animals is a better option to increase the milk yield without compromising milk quality and animal health

Functional additives, such as autolyzed yeasts, have been used to achieve greater production efficiency and animal health. These compounds are also alternatives to the use of performance-enhancing antimicrobials. The objective was to evaluate the productive performance, ingestive behavior, apparent digestibility of feed DM and the carcass characteristics of beef steers finished in feedlot receiving autolyzed yeasts in the diet. The experimental design was randomized blocks, consisting of three treatments and six repetitions, where each repetition was represented by a stall with two animals. 36 bulls, ½ Angus × ½ Nelore blood, from the same herd, with an average age of 11 months and an average body weight of ± 330 kg were used.The treatments were as follows: CON - yeast-free diet; Y4 - yeast diet (4 g animal day-1) and Y7 - yeast diet (7 g animal day-1). The product used is a functional ingredient containing the yeast Saccharomyces cerevisiae. The inclusion of autolyzed yeasts resulted in greater daily body weight gain and better feed conversion in the initial feedlot phase. The apparent digestibility of DM of diets containing autolyzed yeast was superior to the control diet, and its use did not interfere with the animal ingestive behavior. Supplementation with autolyzed yeasts at the inclusion level of 4 g day-1 promoted better results in the finishing of feedlot steers, and that the supplemented groups (4 g animal day-1 and 7 g animal day-1) achieved the same degree of carcass finishing, higher than the control group.

The aim of this study was to evaluate the influence of the biopreparation Deodoric® on ammonia (NH3) concentration, performance, and hygiene standards in laying hen (ROSS-308) production. Statistically significant differences in NH3 concentration and the body weight of laying hens were observed between the control group (C) and the experimental group (E) where Deodoric® was applied at the set dose. In the control group, an increase in NH3 concentration could have contributed to the decrease in the body weight of laying hens, egg production, and % hen day egg production, whereas no such correlations were observed in the experimental group. A moderate linear correlation between NH3 concentration vs. humidity (r = 0.68), air flow (r = 0.48) and weakly linear correlation between NH3 concentration and age of birds (r = 0.27) was noted in group C. In group E, NH3 concentration vs. temperature (r = 0.27) and humidity (r = 0.14) were weakly correlated. Statistical analysis of changes in the microbial counts isolated from manure revealed a significant decrease of mesophilic microorganisms on day 28 decrease of Campylobacter spp. days 14 and 84 in group E. However, for the entire experimental model no statistically significant changes in the number of Campylobacter spp. and mesophilic bacteria were found. The tested preparation did not cause changes in the microbial composition of tissue swabs. Deodoric® contributes to animal welfare by reducing the ammonia concentrations in poultry houses. It is also recommended for use in poultry farms to improve animal health and performance and to generate benefits for producers.

AbstractIn this research communication I show the effect of various cow–calf contact systems on milk yield and milk composition during the periods when calves where allowed to suckle their dams and after the calves were separated in comparison to cows that were only machine milked throughout their lactation. Analyses were based on four different experiments, but conducted at the same research station and under comparable housing and feeding conditions. Nursing dams had contact to their calves during the whole day, during night-time or only twice per day shortly before milking. A control group of cows that had no contact to their offspring was part of every experiment. Data of the regular monthly milk recordings were analysed with linear mixed models. Results showed a significant effect of the suckling system on the machine milk yield over the whole lactation. While cows with night-time contact reached the milk production level of the control cows, cows with whole day or short-time contact still produced less milk after the calves were separated. Fat content was always lower during the suckling period but not afterwards. The significantly higher milk protein content in dams with calf contact requires further investigation. Somatic cell count in milk of nursing dams was slightly increased, probably due to the exposure of the teats to frequent suckling in addition to machine milkings. In conclusion, cow–calf contact systems influence the performance of cows during and after the suckling period but to varying degrees depending on the system adopted.

Beneficial Effects

In dairy cows, immunosuppression occurs frequently during the periparturient period and is characterised by transient neutropenia and impaired polymorphonuclear neutrophil function. As a consequence, postpartum cows are more susceptible to production-related diseases such as mastitis, retained foetal membranes and metritis. Recently, it has been shown that a double injection with recombinant bovine granulocyte colony-stimulating factor covalently bound to polyethylene glycol (PEG rbG-CSF) increased polymorphonuclear neutrophil number and the exocytosis of myeloperoxidase by stimulating polymorphonuclear neutrophil, which also played a role in innate uterine immune defence. The aim of this randomised clinical study was to investigate the effects of two periparturient PEG rbG-CSF injections (IMR; Imrestor<sup>TM</sup>, Elanco Animal Health, Bad Homburg/Germany) on the incidence of acute puerperal metritis, number of antibiotic doses required for treatment of acute puerperal metritis as well as parameters of milking performance (i.e., milk yield, milk fat, milk protein, and somatic cell count on the first dairy herd improvement test day) in primiparous cows within a dairy herd with an elevated incidence of acute puerperal metritis. In total, 169 heavily pregnant heifers were randomly assigned to the treatment group (IMR: n = 82) who received 15 mg PEG rbG-CSF subcutaneously 10 ± 3 days before the anticipated calving date and within 24 hours after calving, or to the untreated control group (Co: n = 87). In total, data from 157 animals (IMR: n = 75, Co: n = 82) were analysed. Administration of PEG rbG-CSF reduced the incidence of acute puerperal metritis in primiparous cows significantly (IMR: 22.7%, Co: 43.9%, P = 0.003; relative reduction: 48.3%). Moreover, the number of antibiotic doses per calving required for treatment of acute puerperal metritis was significantly lower in the pegbovigastrim group (IMR: 0.32 ± 0.66, Co: 0.59 ± 0.75, P = 0.005). No significant differences regarding incidence of clinical mastitis, milk production or milk composition were observed. These results suggest that further research should be performed to identify herd- and animal-specific factors that can be predictors of the beneficial effects of pegbovigrastim in preventing uterine diseases.

Aim. The objective of this study is to investigate the effectiveness of Crossfit training in order to minimize performance loss of elite wrestlers during 30-day rest period. Materials and Methods. Total 23 elite male wrestlers who competed at the last national championship participated in this study. The participants were divided into two groups as Crossfit and control group. The Crossfit group performed 5 pull-ups, 10 push-ups and 15 squat exercises consecutively (Crossfit-Cindy) for total 20-min, during the 30-day period, 6 days per week. The Control group did not perform any exercise programs during this period. Before and after the 30-day period, athletes were applied anthropometric measurements as well as VO2max (aerobic capacity), bench press and squat (maximal dynamic strength), leg and handgrip strength (isometric strength), pull-up and push-up (strength endurance) tests. Results. After the 30-day period in the control group, body weight and body fat percentage (BF %) increased significantly, whereas all performance variables decreased significantly. Maximal dynamic strength and aerobic capacity values decreased significantly in the Crossfit group, while body weight, body fat percentage, isometric strength and strength endurance values were maintained. Moreover, the decrease in VO2max and bench press tests was higher in the control group than in the Crossfit group. Conclusion: Consequently, the present study showed that 20-min Crossfit training was highly effective in maintaining the form of elite wrestlers during a 30-day rest period

Background: Obesity is known as one of the most important cardiovascular risk factors. Objectives: This quasi-experimental study was conducted to investigate the effect of an eight-week aerobic exercise and garlic extract use on the blood pressure, fat percentage, and lipid profile of patients with hypertension. Methods: A total of 50 men with a mean age of 53 ± 7.6 years were recruited from among obese patients with blood pressure. They were randomly divided into five groups of aerobic exercise, garlic extract, aerobic exercise plus garlic extract, placebo, and control. The experimental groups underwent aerobic exercise (3 sessions per week, each session for 35 - 60 min with a maximum heart rate of 50 - 75) or garlic extract supplementation (daily use of 6 g) for eight weeks. Blood samples were collected before interventions and 48 h after the last exercise session. Statistical analysis was done by the dependent t-test and ANCOVA. Results: Body weight, body fat percentage, systolic and diastolic blood pressures, and serum LDL significantly reduced in the aerobic exercise, garlic extract, and aerobic exercise plus garlic extract groups compared to the control group (P ≤ 0.05). Aerobic exercise and aerobic exercise plus garlic extract groups showed a significant decrease in total cholesterol level and serum triglyceride and an increase in serum HDL compared to the control group (P ≤ 0.05). Aerobic exercise plus garlic extract group indicated a higher increase in serum HDL and a higher decrease in the body weight, body fat percentage, and serum LDL compared with the control group (P ≤ 0.05). Aerobic exercise plus garlic extract group indicated a higher serum LDL decrease compared to the aerobic exercise group (P ≤ 0.01). Conclusions: Both aerobic exercise and garlic extract seem to be able to improve obesity, lipid profile, and hypertension. However, their concurrent use has no additional effects on the blood pressure control although it mostly influences lipid profile and body composition.

An experiment was conducted to study the effect of micronutrients supplementation on body weight of cows, birth weight of calf, colostrums composition, milk yield and milk composition. Six animals were divided in to two groups viz. control and supplemented group. Control group was provided conventional diet and supplemented group was supplied conventional diet plus vitamin-mineral mixture (1g vitamix powder/1kg concentrate feed) respectively for two months before calving. In supplemented group the average daily gain of the cows was (49.17 g/d) higher (P<0.01) and the calves were 2 kg heavier in supplemented group compared to control group. Fat content and protein content of colostrum in supplemented group were also significantly higher (P<0.01 and 0.05). The milk yield, fat and protein values of milk were increased non-significantly by 1.03 kg/d/h, 2.8 g/kg and 0.3 g/kg respectively. Ca content of milk was more or less similar in both cases.

Abstract Several factors influence the overall maintenance requirements of a mature beef cow including age, gain, lactation, pregnancy, and fleshing ability. However, limited research is available to distinguish what sets a hard-fleshing cow apart from an easy-fleshing cow. Cows that are hard-fleshing maintain a lower body condition score (BCS) throughout the year compared to easy-fleshing counterparts. The objectives of this experiment are to determine the differences in characteristics and production between cows classified as easy- vs. hard- fleshing. Characteristics of interest include feed intake, milk yield, milk composition, body weight changes, BCS changes, and other body composition measurements, as well as calf weaning weight. In this study, 24 spring-calving, mature Angus beef cows were classified as either hard-fleshing or easy-fleshing based on BCS and ultrasound measurements for back fat and rump fat. The intake study took place during the second trimester, cows were assigned to an easy- or hard-fleshing pen based on treatment where they remained for the entirety of the 45-day intake study. Each treatment was replicated three times in a completely randomized design. Milk data collection began one month after calving with monthly milkings from May-August. There were no differences (P = 0.9) in DMI, although hard-fleshing cows had greater DMI calculated on a metabolic body weight basis (P = 0.05). There was a trend (P = 0.12) for hard-fleshing cows to wean heavier calves, although there was no difference in mean milk yield (P = 0.44). Body condition score was positively correlated with protein and carbohydrate content of milk with easy-fleshing cows having greater contents of both (P = 0.02 and P < 0.01, respectively). Overall, an increase in BCS without an increase in DMI may be beneficial from a reproductive standpoint, though more research in this area is needed.
