Along the increasing number of live born piglets in a litter, which reduce the newborn live weight, plays the colostrum nutritional quality an essential role to the survival of newborn piglets. Concentration of colostrum nutrients is affected with several factors from which the time from the start of parturition has the greatest impact. On the second place is nutrition of pregnant sows. A lot of scientific articles were published with the goal to describe sow's colostrum nutrients. In this review we would bring closer look on the sow's colostrum, where the concentration of energy, immunoglobulins and amino acids are the main determinants for successful survive of piglets first days of life.

Proteins in the urine of healthy individuals of various species are present in trace, practically immeasurable amounts. Under physiological conditions, the renal glomeruli filter out proteins with a molecular weight below 69 kDa, which are then almost completely reabsorbed in the proximal tubules. Occasionally, as an effect of low temperature, physical exercise, rapid change of body position, high-protein diet, medications, or at the end of pregnancy and in the postnatal period etc., proteins may be present in the urine of healthy individuals in higher amounts. This condition is referred to as physiological proteinuria. Most often, however, proteinuria is a symptom of a kidney disorder and may lead to further damage, eventually to renal failure. Proteinuria may be a result of: (a) increased penetration of proteins, mainly of low molecular weight, through the normal filtration membrane and the inability to absorb the increased amount of proteins in the proximal tubules – overflow proteinuria, (b) increased permeability of the glomerular filtration barrier, most often as a result of its damage – glomerular proteinuria, (c) damage to the renal tubules due to failure of reabsorption mechanisms – tubular proteinuria. Excretion of larger amounts of protein in the urine is always indicative of dysfunction of the kidneys and/or of the urinary tract. Having knowledge on the kind of excreted proteins (in terms of weight/size of the molecules) is very useful in medical and veterinary practice, as it enables early identification of the causes of proteinuria and distinguishing its etiology. In recent years, much attention has been paid to the role of uromodulin as a diagnostic marker of an early phase of renal dysfunction, especially of the tubules. The observations on the interaction of the digestive and excretory systems in the regulation of proteonemia in the postnatal period also seem to be important.

The agricultural employed population of the year 2020 in Taiwan were 548,000 persons with 74.1% male and 24.9% female. Only 10.9% of those were young farmers with age of 15 to 34 years old. According to the survey of animal industry in 2020, there were about 10,300 livestock farms and 9,900 poultry farms in Taiwan. For those of producing milk, meat and egg in different sectors, the average annual incomes per farm is more than 20 million Taiwan dollar in dairy cattle farms and broiler chicken farms with number of rearing animals per farm were 210 cows and 27,618 birds, respectively. Farm animal genetic resources of 117 breeds in Taiwan updated to 2021, including 20 native breeds, 43 imported breeds, 39 registered new breeds, and 15 ongoing selection breeds, serve as a gene bank for the study of genetic diversity. In Taiwan experience, mule duck production with two species crossbreeding via artificial insemination of laying duck sired with mixed semen from Muscovy duck, it is an essential application of multiple-sires instrumental breeding. In free range production, females of native chicken and laying duck can be multiple-sire natural mating to ensure a higher fertility rate of ovulated eggs. Application of frozen semen and embryo may perform sire-daughter mating, brother-sister mating, or son-dam mating for increasing genetic homogeneity without inbreeding depression of reproduction performance. Inbreeding quickly brings to the surface any detrimental genes that are in a population. With the facility of paternal DNA test, single-sire breeding can be used with extended semen and intra-uterine insemination to test the allele effect of sire genome on their economic traits of pig, cattle, goat, and poultry breeds in a small-scale farming system. Advanced breeding efforts are undertaken to broaden the genetic base of conserved animals and create new breeds that meet the manifold demands in relation to quality, resilience, and sustainability in small-scale farms.

Hemp (Cannabis sativa L. subsp. sativa) is a rich source of cannabidiol (CBD) and tetrahydrocannabinol (THC). In this plant predominant is CBD, which is devoid of psychogenic properties. Hemp has quite a wide range of uses, ranging from cosmetology to the food and pet-food industries. CBD has many pharmacological effects, including antipsychotic, anxiolytic, sedative, antiepileptic, anti-inflammatory, analgesic, antiemetic, antidiabetic and anti-ischemic effects. All these effects can be convincingly explained by the observations regarding the mechanism of action of CBD. However, it is not known in what dose hemp would cause the above-mentioned effects. Although CBD oil may have therapeutic potential, the scientific evidence supporting its use in animals is currently limited, and there are few well-controlled studies, most of which focus on companion animals.

This study was aimed to determinate the best model to predict milk dry matter in high milk yielding dairy cattle. Level of milk dry matter (MDM) (%) is of great importance. The material of this study consisted of 2208 milking records of dairy cattle yielding more than 40 l per day from Polish Holstein Friesian population. In this study to estimate the milk dry matter, regression of daily milk yield (MY) (l), milk urea (MU), milk protein (MP) (%) and milk fat (MF) (%) as explanatory variables were used. To estimate the best fitting, curve estimation was used. Estimation of the curves showed that milk urea was cubic, milk yield, milk protein and milk fat were quadratic. To avoid multicollinearity where VIF value greater than 10, stepwise variable selection procedure was used. After variable selection the regression equation was obtained as MDM=2.879+1.290*MF+2.395*MP-0.039*MF^2–0.225*MP^2 with 0.946 coefficient of determination. Our results showed that milk fat (%) and milk protein (%) can be used to estimate the milk dry matter (%) with a great achievement in high milk yielding dairy cattle.

West Pomerania is one of the richest regions in Poland when it comes to big game. The review is a comparison of the weights of carcasses and antlers of red-deer stags and roe-deer bucks harvested in the West Pomeranian Voivodeship with data from other regions of Poland. It was found that the weight of the carcasses and antlers was average compared to those assessed in other regions of the country. High and significant correlations were also found between carcass weight and antlers weight in both stags of red deer and bucks of roe deer.

Morphological changes of the vertebrae, whether congenital or acquired, are more and more frequent causes of movement difficulties of both humans and other species of mammals. The most frequently diagnosed pathologies of the spine include: degenerative changes, congenital defects, inflammatory diseases, and proliferative changes. This article presents the characteristics of selected morphological changes in the spine, the reasons for their occurrence, and the diagnosis. Some of abnormalities have a genetic basis, sometimes already known, such as in the case of vertebral deformity syndrome in domestic cattle, which is caused by a mutation in the SLC35A3 gene. At other times, the genetic factor is only speculated as in the case of human scoliosis - some studies indicate its autosomal dominant nature of inheritance.

Locomotor diseases in cattle can have various causes, both infectious and non-infectious. Infectious agents, such as bacteria, mainly cause finger dermatitis and interdigital dermatitis. In turn, the non-infectious factors include deformation of the claws and the animal housing system, including the bedding material in the barn. Orthopedic disorders and diseases generate financial losses due to lower milk yield, extension of the calving period, or the need to implement treatment. Moreover, animals suffering from any hoof dysfunction suffer from reduced welfare, which results from the sensation of pain, discomfort, and stress associated with a hoof injury or deformation of the claw, or an infection developing on the bovine hoof. It is necessary to take measures to prevent the appearance of diseases and dysfunctions within the cow’s hooves, and early detection of disorders is associated with faster implementation of treatment.

he aim of this study, conducted under identical environmental conditions and the stanchion barn housing system, was to compare milking performance traits and somatic cell count in milk of daughters sired by Holstein-Friesian Black-and-White bulls from various origin groups. Cows were divided into three groups depending on the region of sire's origin, i.e. Polish bulls, bulls from other European countries (the Czech Republic, France and Germany) and bulls from the USA. Analyses were conducted applying the following experimental conditions: the age group of cows (primiparous vs. multiparous), stage of lactation (≤ 40 days, from 41 to 100 days, from 101 to 200 days and > 200 days) and season of the year (spring, summer, autumn and winter). Results of this study indicate that at the stanchion barn housing system of dairy cows in order to increase milk yields the use of semen from bulls of imported Holstein-Friesian Black-and-White bulls seems to be beneficial. However, daughters of US bulls may be prone to elevated somatic cell counts in milk. In turn, cows sired by Polish bulls can be characterised by favourable milk solids contents.

The aim of this study was to analyse the effect of pepper (Capsicum annuum L.) oleoresin (PO) and rosemary (Rosmarinus officinalis L.) extract (RE) on the quality of ground pork (m. longissimus dorsi). Vacuum-packaged pork samples were cold-stored for 4 weeks. The quality of meat without additives and with the addition of PO (0.4 and 0.2 g · kg–1 meat) and 4% RE (0.6 and 0.3 g · kg–1 meat) was evaluated. The pH of vacuum-packaged ground pork decreased during 4 weeks of storage in all experimental groups. The rate of lipid oxidation and changes in the colour and sensory properties of stored meat were determined by the type and quantity of natural antioxidants. Rosemary extract added at 0.6 g · kg–1 meat was the most potent inhibitor of lipid oxidation. Pepper oleoresin added at 0.4 g · kg–1 meat had the most beneficial influence on colour intensity evaluated instrumentally and colour desirability evaluated visually. Pork containing RE added at 0.3 g · kg–1 meat was characterised by the most desirable aroma and taste after storage.
