Diurnal Behaviour

Three experiments were conducted with the objective of evaluating the effects of supplementation (concentrate or mineral supplementation), supplementation strategy (continuous or strategic supplementation) and gender class on the ingestive and diurnal behaviour of grazing beef cattle. To evaluate the effect of the supplementation (Experiment 1) and the gender class (Experiment 3) on their diurnal behaviour, behaviour visualisations were performed by two people at observation stations outside the picket area with the aid of binoculars. The animal behaviour was classified as: supplement intake, grazing, water intake, standing ruminating, standing idle, lying ruminating, lying idle and walking. To evaluate the effect of the supplementation strategy on the ingestive behaviour of the supplement (Experiment 2), refusals of the supplement were weighed for six consecutive days at different times (20, 40, 60, 90, 120, 180, 240, 480 and 1,440 minutes) after the concentrate was supplied. The intake of concentrate per animal, at each observation time, was calculated by subtracting the weight of the scraps at that time from the total weight of the batch of supplement provided on the day, and dividing the result by the number of animals in each batch. Finally, a logistic model was adjusted for each treatment. A 10% significance level was adopted for all statistical procedures. Concentrate supplementation reduced the time that the animals spent grazing. The continuous supplementation strategy affected the uniformity of the supplement intake speed, without affecting the average speed or the total supplement intake. The gender class of the animals also influenced their diurnal behaviour, castrated males spent more time lying, compared to females. The specificities of cattle behaviour should be considered when delineating the supplementation of grazing cattle, since the type of supplement, previous supplementation and gender class interfere with their behaviour.

Post Mid Term Review of the Common Agricultural Policy, beef production must survive in a subsidy-free, market led environment. It is essential that producers increase final carcass value by achieving cost effective performance from birth to slaughter. The aim of the present study was to evaluate the effects of plane of nutrition during the growing and finishing indoor feeding periods, and stocking rate and concentrate supplementation at pasture on the performance of steers and heifers from weaning to finishing.

Abstract Our objective was to evaluate the effects of mineral supplementation using the association of carboaminophosphochelates as mineral source plus Salinomycin on grazing beef cattle performance during growing phase. A total of 80 Nellore bulls (IBW = 292.72 ± 13.55 kg; Age, ~13 mo) were distributed in 8 paddocks (~2.7 hectares each) planted with Palisade Grass cv. Xaraés during the rainy to rainy-to-dry transition seasons (February to May). The experiment was a randomized complete block design (10 animals/paddock, 4 paddocks per treatment). The mineral supplementation was provided ad libitum and treatments were: Control; Mineral supplementation containing inorganic minerals, and TM+Salinomycin = Mineral supplementation containing carboaminophosphochelates (TM, Tortuga® Minerals) as minerals source (Cr, Se, Zn, Mn, S, Cu e Co) plus Salinomycin (~108 mg per animal/day). The supplement orts were removed and weighted daily to calculate supplement intake. The animals were weighed after a 14 h-fasting at the beginnig and end of the trial (84 days) to calculate weight gain. The paddock was considered the experimental unit and data were analyzed using PROC MIXED of SAS, whereby means were separated using the PDIFF statement (P < 0.05). Supplement intake was similar between treatments (P = 0.13). Animals supplemented with TM+Salinomycin tended to have greater final BW (358 vs. 347, P = 0.07) and increased ADG in 22,3% (0.730 vs. 0.597 kg/d, P = 0.03) compared with animals fed Control. In conclusion, the combination of carboaminophosphochelates minerals plus salynomicin improves grazing beef cattle weight gain, with no deleterious effect on mineral supplement intake.

Context Cupuassu is frequently cultivated in Brazil as well as in the warm lowlands of other tropical American countries. Cupuassu nut contains high levels of theobromine and ether extra ct, which could negatively affect the intake and digestibility of nutrients, when included in livestock diets. Aims The present study was undertaken to evaluate how replacing maize with cupuassu nut affects feed intake, efficiency of microbial synthesis and nitrogen (N) balance in Nellore bulls at pasture. Methods Five Nellore bulls with an initial bodyweight of 336.7 ± 12.8 kg (mean ± s.d.) were kept in individual paddocks of Urochloa brizantha cv. Marandu. Concentrate supplements containing equal amounts of N and different concentrations of dried whole cupuassu nut (0%, 25%, 50%, 75% or 100% replacement of maize) were fed to bulls in a 5 × 5 latin square design, with each animal allocated to each diet for a period of 20 days, including a 14-day period of adaptation. Key results Intake of all dietary components and total digestible nutrients, except ether extract, theobromine and neutral detergent fibre corrected for ash and protein, decreased linearly with the addition of cupuassu. Theobromine intake varied from 13.86 (25% cupuassu nut) to 36.67 (100% cupuassu nut) mg/kg bodyweight. The inclusion of cupuassu in the supplement led to a linear decrease in ruminal ammonia-N concentration, N balance, and efficiency of microbial synthesis. Conclusion Replacing maize with dried whole cupuassu nut in concentrate supplements reduces the intake of DM from both supplement and pasture, the efficiency of microbial synthesis, and the N balance in grazing beef cattle. Implications The replacement of maize by dried whole nut of cupuassu in concentrate supplements for grazing cattle is not recommended because it reduces supplement intake and nitrogen retention, and it is likely to decrease liveweight gain.

The objective of this study was to evaluate the effects of frequency of concentrate supplementation on the daytime feeding behavior (grazing, rumination, drinking, and idle times), production performance, and economic viability of grazing cattle in the rainy season. A total of 120 uncastrated Nellore animals with an average body weight (BW) of 382.5 ± 32.2 kg were allocated to palisadegrass (Brachiaria brizantha) paddocks for the experiment. We evaluated supplements provided in the amount of 2.0 kg/animal, supplied three times weekly (3tw) or daily (7X). Animals supplemented 3X (5.46%) spent more time (%) drinking water than those supplemented 7X (3.72%). Grazing time and animal performance were not influenced by the frequency of supplementation. Average daily gain was 1.00 and 1.02 kg/animal for the groups under 3X and 7X, respectively. Expenditures on transportation and labor are lower (43%) when animals are supplemented 3X. Supplementation provided three times per week does not affect the grazing time or the performance of beef cattle in the rainy season, but rather implies an expressive reduction of expenditures on labor and distribution of supplements.

AbstractCleft births surveillance is essential in healthcare and prevention planning. Data are needed in precision medicine to target upstream management for at-risk individuals. This study characterizes Singapore’s population-based orofacial cleft topography by ethnicity and gender, and establishes the cleft cohort’s infant mortality rate. Data, in the decade 2003 to 2012, were extracted by the National Birth Defects Registry. Trend testing by linear regression was at p < 0.05 significance level. Prevalence per 10,000 for population-based cleft live births was 16.72 with no significant upward trend (p = 0.317). Prevalence rates were 8.77 in the isolated cleft group, 7.04 in the non-isolated cleft group, and 0.91 in the syndromic cleft group. There was significant upward trend in infants with non-isolated clefts (p = 0.0287). There were no significant upward trends in infants with isolated clefts and syndromic clefts. Prevalence rates were sexually dimorphic and ethnic-specific: male 17.72; female 15.78; Chinese group 17.17; Malay group 16.92; Indian group 10.74; and mixed ethnic origins group 21.73. The overall infant mortality rate (IMR) was 4.8% in the cohort of 608 cleft births, which was more than double the population-based IMR of 2.1% in the same period. Infants with non-isolated and syndromic clefts accounted for 96.6% of the deaths.

AbstractThis paper examines the relationship between employee engagement and job satisfaction. People spend most of their time at work, and their motivation is considered to be an important factor for job performance. Enthusiastic employees, who focus their efforts on achieving their companies′ goals are a key competitive advantage in the modern world. The effect of employee engagement on business performance has been studied by various experts. They found out the similar conclusion: “the more enthusiastic the workers are, the better operating results they achieve for the company”. An occasional sample of 594 respondents who are employed in the public and non-public sector in Slovenia was used for the purpose of this study. The main goal of the research is to determine whether (and how) the employee engagement influences job satisfaction. A written survey was conducted from 4 January 2016 to 14 March 2016. IBM SPSS 20 was used for the statistical analysis. The results confirm that the relationship between employee engagement and job satisfaction is positive and statistically significant (5 % significance level), based on the linear regression F (1, 583) =296.14, p-value = 0.000, R-square = 0.337. The results also show that there is no statistically significant difference between employee engagement and gender and there is no statistically significant difference between job satisfaction and gender.

ObjectivesResearch conducted at the University of Puerto Rico noted that beef with elevated pH values (> 5.86) resulted in more tender meat (P ≤ 0.05). It has been established that proteolytic degradation mechanisms can be influenced by pH and calcium concentration in muscle. Beef with pH values ≥ 5.86 is classified as Dark Firm and Dry (DFD) but there are negative implications associated with greater pH values. However, observations indicating increased tenderness with increased pH raise the question: can variations in pH be associated with differences in sarcomere length (SL) and free calcium concentration (FCC)? Therefore, the objectives of this project were to: (1) document pH distribution; (2) determine the incidence of DFD; and (3) evaluate the relationship between pH, SL, and FCC in commercial cattle harvested in Puerto Rico.Materials and MethodsLongissimus lumborum samples (n = 51) were obtained and background information was noted including number of permanent incisors (PI), type (Dairy or Beef), and gender. The pH values were used to categorize beef into the following groups: Low (≤ 5.40), Normal (5.41 to 5.59), High (5.60 to 5.85) and DFD (≥ 5.86). Meat was flash frozen, powdered, and placed on a microscope slide and a Helium-Neon laser was used to determine SL. A subset of samples was sent off and prepared at the University of Nebraska-Lincoln for FCC quantification (Ward Laboratories; Kearney, NE) with an inductively coupled plasma emission spectrometer (iCAP 6500 Radial; Thermo Electron, Cambridge, UK). All statistical analyses were conducted in SAS (9.4). The Proc FREQ was used to determine pH category distributions and incidence of DFD. The Proc GLIMMIX and Tukey adjustment (α = 0.05) were used to determine the effects of number of PI, type, and gender on pH category, SL and FCC. The Proc CORR was used to evaluate the relationship between pH category, SL and FCC.ResultsThe pH category distribution for the current samples was as follows: 3.92% Low, 41.18% Normal, 35.29% High and 19.61% DFD. The SL ranged from 1.69 to 1.46 mm with an average of 1.53 mm. The FCC ranged from 132.19 to 31.39 mM with an average of 64.23 mM. Longer sarcomeres were detected in cattle with eight and zero PI (1.57 and 1.56 mm, respectively); cattle with two and four PI had intermediate SL (1.53 and 1.52 mm, respectively), and cattle with six PI had the shortest sarcomeres (1.51 mm; P = 0.03). Dairy cattle had longer sarcomeres relative to beef cattle (1.56 vs. 1.52 mm; P = 0.02). Dairy cattle tended to have increased FCC relative to beef cattle (70.72 vs. 58.38 mM; P = 0.08). Also, FCC tended to be greater within the Normal and Low pH categories relative to the High and DFD categories (72.36 vs. 57.31 mM; P = 0.06). The SL and FCC had no relationship (P > 0.05) within the Low, Normal and High pH categories. However, DFD beef had longer SL (0.78; P = 0.01), while having decreased FCC (–0.66; P = 0.04).ConclusionOver half (54.90%) of the beef samples analyzed fell into the High and DFD pH categories, with nearly 20% being classified as DFD. Although, a clear relationship was not established between SL and FCC within the Low, Normal or High pH categories, the results indicate that the increased pH in samples surpassing the DFD threshold correspond to longer sarcomeres and decreased free calcium.

Supplement intake and liveweight (LW) data were collected daily and remotely by digital in-paddock technologies (electronic feeder (EF) and walk-over-weighing scale (WOW)) to study the effect of forage quantity and quality on the intake of a self-fed supplement (molasses-lick blocks (MLB)), LW, liveweight change (LWC), and feeding behaviour of grazing beef cattle. Fifty-two crossbred weaners were rotationally grazed or fed for 254 days on different forages: sudangrass (SG), autumn pastures (P), winter pastures with concentrate (P+C), oat crops (OC), lucerne hay (LH), and oaten hay (OH). Forage quantity and quality were measured on the day of entry (high feed availability) and exit (low feed availability) stages of grazing or hay delivery. The intake of MLB was 111% higher (p < 0.05) at low compared to high feed availability, and this was also reflected in the feeding behaviour of animals (e.g., greater feeding frequency and rate). Moreover, there was a large temporal variability of daily MLB intake (Coefficient of variation (CV) = 146.41%). Supplementing MLB improved LWC only with SG, P, or OH (p < 0.05). The behaviour of animals around MLB reflects changes in feed quantity and quality and could be used to enhance cattle grazing and nutritional management in real time.

The objective of this study was to determine the effect of mineral supplementation on the serum concentration of calcium, phosphorus, and magnesium in pre- and postpartum Blackbelly sheep throughout three successive lambing periods under free grazing conditions in the Ecuadorian Amazon Region. The field work was carried out between January 2015 and February 2018 using 20 Blackbelly sheep belonging to the Centre for Research, Postgraduate Studies and Conservation of Amazon Biodiversity, Ecuador. The flock was randomly divided into two groups: Group 1 (G1) was fed with forage plus a supplementation (Pecutrin® Mineral supplement plus vitamins A, D3, and E. Bayer HealthCare) and Group 2 (G2) was fed only with forage without mineral supplementation. Three blood samples from the coccygeal vein were taken from each sheep 30 days before lambing, 30 days after, and 60 days after lambing. Concerning the average of calcium, significant differences were found at different times inside each group and also between them (p < 0.0001 in both cases). As for the phosphorus, significant differences were found between the means of the groups for all times from 30 days after the second lambing season (p < 0.05). It was observed that the groups differed significantly in terms on the average of magnesium (considering a significance level of 0.05) 30 days before the first lambing and at all times measured from the 30 days after the second lambing (p < 0.005). In this study, we showed that Blackbelly sheep raised under free grazing conditions in the Ecuadorian Amazon Region had very low serum calcium values, and supplementation was unable to improve them. Meanwhile, phosphorus and magnesium levels were below the required values, but after supplementation, they exceeded the minimum threshold. Mineral supplementation in the rearing of sheep in grazing systems is necessary during the entire production cycle, but it must be done taking into account the soil–plant–animal relationship specifically for the Amazonian Region systems.
