Dairy cattle brucellosis is a chronic bacterial disease, which is caused by Brucella abortus and mainly characterized by abortion in dairy cattle. With the rapid development of breeding industry of milk cows in China, the infectious cases of dairy cattle brucellosis show an increasing trend. Particularly in Jilin province, the annual number of the positive cases of dairy cattle was only 3 cows in 1987, and went up to 168 cows in 2005. Based on the situation of the brucellosis infection in Jilin province, we propose an Susceptible-Exposed-Infected-Virus (SEIV) dynamical model with outside transferred amount to describe the transmission of brucellosis amongst dairy cattle in this paper. We calculate the basic reproduction number R0 and prove that the equilibria are globally stable. Moreover, using the real data of nearly 20 years in Jilin province, we estimate the parameter values in the system. As a result, we can predict the number of infections as time increases. According to the prediction for the next 30 years, we can conclude that the disease will persist if we just take existing measures. If culling, sterilizing and decreasing the number of outer importing are used together, dairy cattle brucellosis will be well controlled.

ABSTRACT Although vulture feeding stations are a widely used tool for vulture conservation in many regions worldwide, there has been some confusion about their functions and this is reflected in the range of terminology used. The origin of food supply at provisioning sites (both for in situ and ex situ situations) and the goals of feeding station managers (ranging from purely conservation of vultures to the necessity for carcass disposal) are two key aspects that are often neglected. We review the definitions and nomenclature for the provision of predictable anthropogenic food for vultures and vultures' role in sanitation in the landscape. We propose that “supplementary feeding stations for vultures” (SFSV) defines a particular case and this term should only be applied when a station has vulture conservation goals and a food supply coming from outside of the landscape (ex situ). We introduce the term “recycling station with vultures” (RSV) for cases when the goal is the elimination of carcasses and the food is sourced in situ (natural, NRSV) or ex situ (supplementary food, SRSV). This clarification of goals and terminology for feeding stations worldwide could have important consequences for the understanding and assessment of vulture conservation and management actions, among researchers and conservationists and also importantly among stakeholders and wider society.

Obesity is a common problem in cats. In the experimental cat family of the institute of animal nutrition besides a “normal” lean phenotype, cats with predisposition to an overweight phenotype are present. To investigate energy requirements and food intake behaviour of intact male cats of different phenotypes, six “normal” lean cats (GL) and six cats disposed to overweight (GO) were used. At the beginning of the experiment, all cats had an ideal body condition score of 5. To reach this the GO cats had to pass a weight-loss program. Energy requirements of the cats were determined using respiration chambers, whereas the amount and frequency of food intake was measured with a feeding station recording the data automatically. Energy requirement at weight constancy of the GO cats was even on fat-free mass (FFM) significantly (P=0.02) lower (162.6 kJ/kg FFM/d) than that of the “normal” lean cats (246 kJ/kg FFM/d). The GO cats also showed a higher food intake34.5±1.5 g dry matter/kg body weight0.67compared to the GL cats (24.0±2.1 g dry matter/kg body weight0.67)(P=0.001). In conclusion quantifiable differences in food intake and behaviour in cats predisposed to overweight compared to “normal” lean cats were found.

Investigations were carried out on milk cows of Black -and- White breed being in 2-nd lactation 30-120 day after parturition. Experiment was performed during winter feeding season (corn silage, fodder beet silage, super beet pulp, concentrate, meadow hay). Cows of the experimental group received supplement (5% of concentrate) of the herb mixture in feeding ratio. The composition of this mixture was as follows: Urtica dioica, Fructus carvi, Pradix teraxaci, Agrimonio eupatoria, Matrica chamomilla. The obtained results show that supplementation of the diet by herb mixture induced increase of the following parameters: milk yield (+2 kg), fat content (+0,04%), protein content (+0,06%), citric acid (+0,10%), whey proteins (+0,02%), casein (+0,04%), dry matter (+0,12%), non fat dry matter (+0,07%). It was stated that in the experimental milk non-saturated fatty acid level was higher (+20%), in opposite to lower level of saturated fatty acids (-15%) and total cholesterol (-25%). The beneficial effect of herb mixture supplementation on the results of rennet-fermentation test, fermentation test, Sehern' s test and heat stability was stated in the experimental group milk.

The aim of this paper is to demonstrate the archaic status of the Polish folk beliefs about certain amphibians (frogs, toads) and reptiles (snakes, lizards, salamanders) believed to have sucked milk from cows. Some Polish peasants were even convinced that milk cows loved suckers (esp. snakes, frogs) more than their calves. There are many folk tales where a witch or a mythical creature assumes the form of a armful animal to suck cow’s milk. The author demonstrates that the oldest part of these beliefs can be traced to the Proto-Indo-European cultural heritage. In fact, some Indo-European languages have preserved a clear indication of animal cow-suckers in their vocabulary, e.g. Ukr. молокосúс m. ‘lizard, salamander’ (literally ‘milk-sucker’); Lith. žaltỹs, žalktỹs m. ‘a not-venomous snake, esp. the grass snake, the slow worm’, Latv. zalktis, zaltis m. ‘snake’, Latg. zalkts m. ‘the grass snake’ (< PIE. *ĝolh2ktii̯os adj. ‘delighting in milk’ < PIE. *ĝl̥h2kt- n. ‘milk’); OInd. gōdhā́- f. ‘a big lizard’ (< PIE. *gu̯h3eu̯-dheh1- f. ‘a cow-sucker’, cf. PIE. *gu̯h3eu̯s f. ‘cow’ and *dheh1- ‘to suck’); Lat. būfō m. ‘a toad’ (< PIE. *gu̯h3eu̯-dhh1-ōn- m. ‘a cowsucker’); Alb. thithëlopë, also blloçkëlopë f. ‘common toad’ (literally ‘sucking/ chewing cows’); Hitt. akuu̯akuu̯aš c. ‘a toad’ (literally ‘sucking cows’, cf. Hitt. aku- ‘to drink’). It is assumed that the Indo-European beliefs were associated with breeding of cattle and were an attempt at a rational (or not) explanation of the alleged cause of poor lactation or cows’ milk loss. It is likely that the ailing animal was perceived as possessed by a demonic character, although the association of an animal with a witch or a devil was made relatively late and probably under the influence of beliefs from Western Europe.

Based on the results of previous studies on pigs and poultry, in which encouraging results of a significant decrease in the concentration of heavy metals in the body were obtained, respectively, in pork, poultry and eggs, the study provided for the use of the bentonite clay of the Zamankul deposit (RNO-Alania) as an enterosorbent in relation to heavy metals and detoxification of the organism of dairy cows. In order to study the feasibility of using bentonite as an enterosorbent, studies were performed on dairy cows of the Simmental breed in the Kaloyev farm located in st. Zmeyskaya, Kirovsky district of North Ossetia-Alania. To conduct research on the principle of analog pairs, two experimental groups of cows (control and experimental, five cows in each group) of the 3rd and 4th lactation were formed. The experiment lasted for 305 days of lactation from March 2018 to January 2019. Herewith, the control group of cows was fed with a basic diet balanced in all nutritional elements, the experimental livestock, together with the main diet, daily in the composition of the concentrates was injected with crushed bentonite with a particle diameter of 4-6 mm based on the dry matter of the feed (137 g/animal). The study of the concentration of heavy metals (cadmium, lead and zinc) in soil, feed, blood and milk was performed in two periods of lactation (on the 250th and 300th days of lactation). Herewith, an increased content of heavy metals in the soil was established, relative to the MPL: cadmium - 10.1; lead - 7.4; zinc - 9.7 times more, in drinking water: cadmium - 2.5 times; lead - 9.0 times and zinc - 9.7 times more, in feed: cadmium - from 1.7 to 5.3 times; lead - from 1.1 to 1.7; zinc - from 1.0 to 2.5 times the MPL. The inclusion of bentonite to the ration of the animals of the experimental group, in comparison with the control group, in both study periods (250 and 300 days of lactation) contributed to a significant decrease in the concentration of the studied heavy metals in the blood from 17 to 20%, in milk - from 16 to 18 %. The transformation ration values of heavy metals from feed into the body, respectively, into milk, were also lower in the animals of the experimental group, relative to the control.

Primarily because of its half-life, the longest-lived radionuclide of copper, 67Cu (half-time 61.7 h), is often the isotope of choice for application in metabolic studies. However, large-scale production of 67Cu is cumbersome. The 67Cu used in this study was produced in a cyclotron by exposing a zinc target to a beam of accelerated protons. Radiochemical purification was achieved by solvent extraction, electroplating and ion-exchange, in that order. The resulting dilute acidic solution contained no measurable activity apart from 67Cu and 64Cu. After the injection in cows, the 64Cu component of the preparation of radiocopper could be used during the first days of the experiment for external radioassay of the liver. The 67Cu could be followed in metabolic products for over 3 weeks. It is concluded that the isotope 67Cu in batches of about 100 mu Ci can very well be used for metabolic excretion studies even on large animals.

Abstract The objective of this research was to determine the effect of competition for a feeding space at an automated supplement feeder on supplement intake behavior. A 2 yr study was conducted; each yr, 128 mixed-breed beef steers (n = 256, initial BW = 245 ± 27.5 kg) were randomly assigned to 8 paddocks. One paddock each yr (n = 16 steers) was selected to have continuous access to the feeder for the duration of the 16 wk trial; this paddock was designated the “tester” paddock. The automated feeder had 4 feeding stations that dispensed supplement after eligible animal’s RFID tags were read by the electronics of the feeder. Steers were limited to 0.50 kg supplement/d. Weekly, additional paddocks were commingled with the tester paddock to increase competition for the feeder. This resulted in a stocking density from 4 to 32 steers per feeding station. For yr 2, one feeding station was disabled, resulting in a stocking density of 5.3 to 42.7 steers per feeding station. Approximately 31% of the steers did not voluntarily use the feeder; therefore, effective competition was less than the study design. Mean weekly supplement intake and GPS location were recorded for steers in the tester paddock. Additionally, pedometer data were collected in yr 2. Weekly mean supplement intake and time spent near the feeder were regressed on actual feeder stocking density with yr as a random variable; wk was the experimental unit (n = 16 wk). Tester steers consumed an average of 0.27 kg supplement/d. Competition for a feeding station numerically reduced (P = 0.01) supplement intake by 5 g/d per steer of additional competition. Steers spent 4.4% of the time within 15 m of the feeder regardless of competition (P = 0.54). As competition increased, steers took more steps (P &lt; 0.01). These data illustrate that in environments similar to this experiment, the feeder can be stocked with at least 20 animals per feeding station with minimal effects on supplement intake.
