The Impact

The aim of this study was to determine the impact of the length of calf sucking milk from its own mother on calf growth at the age of 3 months and milk yield of mothers. We tested a hypothesis that the nursing of calves by their own mothers increases the body weight of calves and decreases the milk production. 50 Holstein primiparous cows and their calves were divided into three groups according to the sucking length of calves: 7 days (A), 14 days (B) and 21 days (C). All calves suckled mother's colostrum and milk while mothers were milked twice per day. After weaning from mother calves were kept in individual hutches until 56 days of life, and then in group housing pens. In the period from birth to weaning the calves of group A reached the lowest and the calves of group C the highest daily gains (0.35 kg, 0.46 kg, 0.54 kg; P < 0.01). The lowest gain was recorded in animals of group A (0.55 kg) and the highest gain was reached by calves of group C (0.74 kg) for the period from birth to three months of age. For the first 305 days of lactation cows of group A produced insignificantly more milk than group C (7356.5 kg, 6779.2 kg, 6663.9 kg). A significant difference in milk production was recorded only during the first seven months of lactation (5494.5 kg, 5041.9 kg, and 4872.3 kg; P < 0.05). The long stay of calves with their mothers influences the growth of calves positively, but the milk production of mothers may decrease. Therefore, the stay of calves with the dam within 21 days after birth is not recommended for high-yielding dairy cows.

Abstract Background Intermittent calorie restriction (ICR) is a novel method of dietary restriction for body weight control with the potential to improve obesity-related cardiometabolic markers, but the impact of this diet on subjects with hypertriglyceridemia (HTG) remains unknown. Methods Eighty-eight subjects with overweight or obesity and mild-to-moderate HTG were randomized to the continuous calorie restriction (CCR) group, or ICR group (a very low-calorie diet during 3 days of the week) for 8 weeks (44 patients in each group). Body composition, plasma lipids, glucose, insulin, adiponectin, and liver enzymes were measured at baseline and after 8 weeks. An intention-to-treat analysis was performed. Results The body weight decreased in both groups (4.07 ± 1.83 kg in the CCR group and 4.57 ± 2.21 kg in the ICR group) with no significant difference between the groups. There was no significant difference between the two groups in the reduced amount of fat mass, fat-free mass, and waist circumference. Both groups achieved a significant reduction in plasma triglycerides after 8 weeks (by 15.6 and 6.3% in ICR and CCR groups, respectively) with no difference between treatment groups. HOMA-IR improved significantly in ICR compared to the CCR group (P = 0.03). Plasma glucose, insulin, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, liver enzyme, and adiponectin were not different between the two groups. Conclusions The results of this short-term study suggest that three-days a week of the ICR is comparable to a CCR diet for the reduction of triglycerides level in patients with HTG and in the short-term it appears to be more effective than continuous dieting in improving insulin resistance. However, longer-term studies are needed to confirm these findings. Trial registration Trial registration number:NCT04143971.

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.

The aim of this study was to assess the impact of the leptin concentration and body weight of mink females on the birth parameters of their kits. Blood samples were collected 3 times during preparation for reproduction, 7±2 days before mating. Total leptin concentration in serum was measured using commercial RIA kits (Millipore, St. Charles, Missouri USA). Research was conducted on 20 clinically healthy scanbrown female minks (Neovison Vison) aged 2-3 years. To evaluate their body condition, the females were divided into two groups based on the BCS scoring system. In the first group, referred to as BCS 2, lean females were included, and the second group (BCS 4) consisted of obese females. In mink dams belonging to BCS 2, the average leptin values were one-fourth of those in the BCS 4 group. The results obtained indicate the influence of the body mass of minks during preparation for reproduction on serum leptin concentration. The results of the Mann-Whitney U test showed a statistically significant difference between weights and leptin concentrations in groups BCS 2 and BCS 4. Among the other traits, such differences were not found. The analysis of results obtained in the two mink groups did not reveal a clear relationship between leptin in the serum of mothers before mating and the birth parameters of their kits.

  Children under five are a group that is prone to malnutrition because they are still experiencing a growth cycle, a development that requires more nutrients than other age groups. The impact of nutritional deficiencies; low body resistance, the body is susceptible to infectious diseases. The purpose of this study was to analyze the effectiveness of giving modified dietetic skim and cotton sheet oil (MODISCO) and Formula-75 milk to increase body weight of malnourished children in Puskesmas Waigete, Sikka Regency. The type of research used is Quasy experimental pretest and posttest design. The population of this research was 181 underweight children with malnutrition. The sampling technique used purposive sampling. The sample of this study was 24 underweight children with malnutrition, divided into 2 (two), namely group A was given MODISCO intervention and group B was given Formula-75 milk. The intervention was given once a day for 1 month at a dose of 150 kcal / kgbb / day for MODISCO and 1000 ml per day for 75 formula milk. Data analysis used Paired t-Test and Independent Samples Test. Paired T-Test analysis, groups A and B obtained P-value (0.000) <0.05, it was concluded that there was an increase in body weight after being given MODISCO and Formula-75 milk. Based on the analysis of the Independent Samples Test, groups A and B obtained a P-value (0.876)> 0.05, it was concluded that there was no difference in body weight for under-nourished toddlers who were given MODISCO and Formula-75 milk. There is no difference in body weight of malnourished underweight children in group A and group B, so it is concluded that MODISCO and Formula-75 milk can increase the weight of malnourished children underweight. The results of this study are an additional intervention to increase the weight of children under malnutrition.

Twenty cows previously shown to be susceptible to bloat were selected to study the effects of bloat on milk production and grazing time in mid-lactation. The cows were either treated with a bloat prophylactic so that no bloat occurred, or were left untreated. They grazed irrigated red clover (Trifolium pratense) pasture, receiving a fresh strip of pasture each morning. Over a period of 184 cow days, there were 116 observed cases of bloat; 16 of these were classified as severe. Milk yield was reduced by 0.14 kg for each hour of bloat (P< 0.01), but there was no significant difference in yield between those cows that suffered mild bloat, and those that suffered severe bloat, despite the obvious acute stress in the latter cases. There was also a loss of 20 minutes of total daily grazing time for each hour of bloat, whether mild or severe. A major part of this loss occurred whilst the cows were bloated. Under the system of management used, it is unlikely that bloat prevention could be justified by the increase in milk production. The only criterion for bloat prevention in these circumstances should be to prevent deaths.

AbstractHippocampal changes in epilepsy may manifest as hippocampal atrophy/sclerosis. A recent human study suggests that the demonstration of hippocampal volume loss is more reliable using quantitative evaluation methods. The aim of the present study was to obtain volumetric data in both epileptic and healthy dogs, to compare hippocampal volumes in both groups, and to compare subjective and volumetric assessment. Volumetric measurements of the hippocampi, lateral ventricles and hemispheria were performed in 31 epileptic and 15 control dogs. There was a positive association between the body weight and the hemispheric volume, as well as between the hemispheric volume and the ipsilateral hippocampal volume. There was no significant correlation between age and the volume of any measured brain structures. There was no statistically significant difference between the hippocampal volumes of the control group and the epileptic group. A statistically significant difference between the two groups for hippocampus/hemispherium ratio or hippocampal asymmetric ratio was not identified. An extrapolated hippocampal volume based on body weight was not possible in this study population.

An experiment was conducted at the Khanpura Poultry Farm, near to the Babugonj campus of Patuakhali Science and Technology University, Patuakhali during the period from August to September, 2011 to evaluate the effect of growth promoter and multivitamin-mineral premix on the body weight gain in broiler chickens. A total of 90 ‘Cobb 500’ day-old broiler chickens were randomly divided into three equal groups (n = 30), namely Groups A, B and C. Broiler birds in groups A and B were supplemented with growth promoter and multivitamin-mineral premix, respectively in addition to commercial feed from day 4 till day 25. The dose of both the growth promoter and multivitamin-mineral premix was 2.5 g/kg of feed. Chickens of group C served as control and supplemented with commercial feed only. Body weight was recorded at three times as on day 11, 18 and 25, respectively. The mean body weight was insignificantly (p > 0.05) higher in birds of groups A (992.5±139.6g) and B (978.3±147.0g) than those of group C (926.7±133.2g). The percent increase in body weight gain compare to control was increased in both the supplemented groups (5.8% in group A and 8.8% in group B) though there was no significant difference. Based on the results, it is suggested that supplementation of growth promoter and multivitamin-mineral premix in broilers even after feeding of commercial feed has positive effect on the growth of broilers.DOI: http://dx.doi.org/10.3329/jbau.v10i2.14914 J.

Factorial Method

The aim of the study is to justify the improvement of dairy cows feeding standards with productivity 8000 kg of milk per year and live weight of 600 kg for the periods of lactation. In developing the standards it was used a new approach to determine the need for energy and nutrients through a combination of scientific and economic experiments with factorial method, which takes into account the physiological needs of the animals, to identify the relationship of the standards feeding with productivity. The scheme of the energy balance in the body of cows that when calculating the standards requirements of the metabolic energy can further take into account the factors of changes in body weight and activity. Developed regression equations and model calculation needs highly productive cows in the exchange of energy and essential nutrients using factorial method, which includes factors need to maintain life, milk production, pregnancy, gain (loss) in body weight and activity of the animals. The effect of feeding for improved standards on nutrient digestibility and utilization of nitrogen, calcium and phosphorus, as well as indicators of rumen metabolism and biochemical status of cows blood with a yield of 8,000 kg of milk per year in the period calved. As a result, feeding cows for improved rate of growth in milk production for 305 days of lactation was 6.0%, with a significant increase in yield of milk fat and protein, and the cost of feed per 1 kg of milk fat standard expressed in the exchange energy were lower than controls at 3.6% in obtaining additional revenue from the sale of dairy products.

SummaryAn Aloe vera and manuka honey commercial supplement (Cow and Calf Formula, DairyCare Ltd, NZ) was fed to approximately 40% of a commercial New Zealand herd with over 1000 cows in lactation following spring calving (August) until the end of lactation (April the following year). The 5 ml of supplement was added automatically to the feed for the treatment group via transponder identification units during at milking. At peak lactation (until October) there was a 5.5% increase (11.76 versus 12.41 litres per milking for control and treated cows respectively; P < 0.001) in yield for the supplemented cows, and over the whole season there was a 4.7% milk yield increase (8.12 versus 8.50 litres per milking for control and treated cows respectively). Data from December and January (high summer) showed no significant increase in milk yield, which was due to a major drought in the area and loss of grazed forage intakes. From these results, it was considered that that the Aloe vera and manuka honey, acting either separately or in synergy, resulted in more nutrients being available for milk production.

The Impact

Slow-release urea (SRU) is a coated non-protein nitrogen (NPN) source for providing rumen degradable protein in ruminant nutrition. A meta-analysis was conducted to evaluate the effects of replacing vegetable protein sources with SRU (Optigen®, Alltech Inc., USA) on the production performance of dairy cows. Additionally, the impact of SRU supplementation on dairy sustainability was examined by quantifying the carbon footprint (CFP) of feed use for milk production and manure nitrogen (N) excretion of dairy cows. Data on diet composition and performance variables were extracted from 17 experiments with 44 dietary comparisons (control vs. SRU). A linear mixed model and linear regression were applied to statistically analyse the effect of SRU on feed intake and production performance. Feeding SRU decreased (P < 0.05) dry matter intake (DMI, -500 g/d) and N intake (NI, -20 g/d). There was no significant effect (P > 0.05) on milk yield, fat-corrected milk, energy-corrected milk, and milk fat and protein composition. However, SRU supplementation improved (P < 0.05) feed efficiency (+3%) and N use efficiency (NUE, +4%). Regression analyses revealed that increasing SRU inclusion level decreased DMI and NI whereas increasing dietary crude protein (CP) increased both parameters. However, milk yield and feed efficiency increased in response to increasing levels of SRU inclusion and dietary CP. The NUE had a positive relationship with SRU level whereas NUE decreased with increasing dietary CP. The inclusion of SRU in dairy diets reduced the CFP of feed use for milk production (-14.5%; 373.13 vs. 319.15 g CO2 equivalent/kg milk). Moreover, feeding SRU decreased manure N excretion by 2.7% to 3.1% (-12 to -13 g/cow/d) and N excretion intensity by 3.6% to 4.0% (-0.50 to -0.53 g N/kg milk). In conclusion, feeding SRU can contribute to sustainable dairy production through improvement in production efficiency and reduction in environmental impacts.
