In addition to genetics, health status and housing management, the milk yield of the dairy cow is also significantly determined by the feeding regime. In addition to the energy and nutrient supply, the dry matter (DM) intake plays a decisive role. This is influenced by many factors, such as the palatability of the feed, the energy density, the quality of the roughage (silage quality, microbiological status, contamination with mycotoxins) or the ration design in total. Water supply of cows is often forgotten, although it has a significant influence on the feed intake and thus the performance of the cows. This article deals with those factors, gives the latest recommendations and points out possible sources of error against the background of feeding not only according to the species-specific requirements but also according to their energy and nutrient needs, as required by the Animal Welfare Act.

Silage Quality

First- and second-cut alfalfa/grass forage crops were wilted to approximately 40% dry matter (DM) and ensiled untreated (control) or treated with either of two enzyme additives to determine the effects on silage quality and animal performance of crops that contain different ratios of legume to grass. An alfalfa enzyme mix (Alfa) contained cellulase, amylase and glucose oxidase; a grass enzyme mix (Grass) was similar but contained no amylase. Both additives contained identical inoculants of lactobacillus. Silage was fed to mid-lactation Holstein cows at 60 d (second cut) and 120 d (first cut) postensiling using repeated Latin square designs. Silage samples and animal performance data were collected during the last 7 d of each of three 28-d feeding periods that comprised each Latin square. Colony-forming units of lactic acid bacteria, concentrations of water-soluble carbohydrate (WSC), ammonia N, acid-detergent fiber N and organic acids, pH, DM disappearance, and temperature changes during ensiling were measured to assess silage quality. Six sheep were also used in a repeated Latin square design to determine digestibility of the second-cut silages. First-cut silage, which contained about 50% timothy, and 50% alfalfa was qualitatively similar across treatments except for a lower (P < 0.05) concentration of hemicellulose in Grass-treated silage. The only effect (P < 0.05) on quality of second-cut silage, which contained about 80% alfalfa and 20% timothy, was an increase in estimated DM loss in Grass-treated silage compared with Alfa and the control. Despite the negligible effects on silage quality parameters, Grass slightly depressed (P < 0.10) the yield of fat-corrected milk in cows fed first-cut silage, and DM intake of cows fed second-cut forage was elevated slightly (P < 0.05) and fat percent was depressed (P < 0.05) by Alfa relative to the control. Consequently, although the change was small, enzyme treatment of forages may represent a means of reducing the fat percent of milk. Sheep consumed more (P < 0.05) second-cut silage treated with Alfa, and DM digestibility was higher (P = 0.09) when compared with the control. An enzyme mixture containing amylase may be marginally more effective when forage mixtures contain more alfalfa than timothy. Key words: Silage, enzymes, dairy, cow, digestibility, milk fat

Silage Inoculants

Timothy (trial 1) and alfalfa (trial 2) were inoculated at ensiling (33–37% dry matter (DM)) in concrete-stave, vertical silos with a culture of lactic acid bacteria (Lab; Lactobacillus plantarum and Pediococcus acidilactici) alone, or with additional nutrients and enzymes (Supersile®, Biotal Canada, Calgary, AB), and compared with an untreated (control) silage. Colony forming units of Lab, ammonia nitrogen (NH3-N), lactic acid and volatile fatty acid concentrations, pH, DM disappearance and temperature changes during ensiling were measured to assess silage quality. Nine dairy cows in mid-lactation (alfalfa) and nine cows in late lactation (timothy) were used to evaluate inoculants in repeated Latin square designs. Timothy silage that had been inoculated with Supersile or Lab had lower concentrations of acetic and butyric acid (P < 0.05) compared with the control. No other effects on silage quality were observed, and cow performance was not affected by using inoculants on either timothy or alfalfa in this study. Enzymes added in this experiment were not beneficial. Key words: Silage, inoculants, alfalfa, timothy, dairy, cow

The article is about the role of the family in the education and formation of children and, especially, in the life and development of autistic children. It describes the problems their family is facing and the need for counseling to parents with autistic children. The reaction to finding the diagnosis of autism varies from one family to another and may encounter a large variety: from disbelief, anger, guilt, helplessness, devastation, surprise, or even rejection of the child, to understanding and relief when finally the parents have an explanation for their child behaviors. Early intervention is important in psychological sustaining of the parent, as parent involvement in the recovery of the child with autism has a determinant role in his development and in ensuring a high quality of life of the child and the life of the hole family. The response to a child's autism diagnosis varies from one family to another. The family goes through a variety of disbelief, anger, guilt, helplessness, devastation, surprise, or even rejection of the child, to understanding and relief. Early intervention is very important in the psychological support of the parent. Because any change disturbs the family equilibrium. A diagnosis of autism changes not only the life of the diagnosed child, but also the life of family members. All the resources are focused on the need of the child. Although each parent is different, after diagnosing the child with autism, all parents are overwhelmed by confusion, shock and denial. Parents' feelings can be influenced by how their children's situation affects different aspects of life - it has an impact on service, on social life and all their personal life. If we look at the family as a system and when a disturbing factor appears, all parts of the system are affected. The involvement of parents in the recovery of the child with autism has a decisive role in its development and in ensuring a high quality of child's life and family life.

The main focus of this research is on the self-concept and pedagogical competence of the teacher and its influence on the quality of the learning process both partially and double. The research method used is a survey method in which the authors go directly to the empirical level by distributing questionnaires to 47 teachers. The processing and analysis techniques used are linear and multiple regression. The results of the study show that: (1) There is a positive and significant influence of the teacher's self-concept on the quality of the learning process (2) There is a positive and significant influence on the teacher's pedagogical competence on the quality of the learning process. (3) There is a positive and significant effect of self-concept and pedagogical competence of teachers together on the quality of the learning process. Therefore, the authors suggest: (1) So that the teacher improves health and appearance because the results of the study show that the weakness of the teacher's self-concept is in the appearance and significance of the body. So that the teacher needs to be given enlightenment related to how to maintain health and fitness through the implementation of joint gymnastics or conducting group discussions related to the dirt to maintain a prime body. (2) To face future competition and improve the quality of education it is deemed necessary to further increase the pedagogical competence of teachers, especially those related to planning and evaluation of learning.

Background: The systemic lupus erythematosus (SLE) patients oftentimes suffer from both physical and psychosocial challenges that may lead to low health-related quality of life (HRQoL). However, limited research has been done in this area. Objective: To examined mental health status and HRQoL among SLE patients in Thailand. Materials and Methods: The present study was a cross-sectional study conducted at the rheumatology clinic of four major hospitals in Thailand. The paper-based questionnaire consisted of demographic, health history such as depression, anxiety, stress Scale (DASS-21), and the Rosenberg self-esteem scale (RSE), and the disease-specific Lupus Quality of Life scale (LupusQoL). Depending on the variable’s level of measurement such as categorical or continuous, Spearman’s Rho or Pearson’s product moment correlation coefficients were used to explore the relationships among the variables. Hierarchical multiple regression was used to identify the predictors of LupusQoL. Results: Among the 387 participants, many might have experienced depression, anxiety, and stress (30%, 51%, and 29%, respectively). Self-esteem among the participants was good (31.8 out of 40). All eight domains of LupusQoL were affected with intimate relationship domain being impacted the most. The overall LupusQoL was significantly associated with the number of prescribed medications (r=–0.23), depression (r=–0.70), anxiety (r=–0.58), stress (r=–0.67), and self-esteem (r=0.59), p<0.001. Significant predictors of the overall LupusQoL were mental health status (depression, anxiety, and stress) and self-esteem, F (3, 81)=43.10, p<0.001, adjusted R²=0.60. Conclusion: SLE patients should be holistically assessed in both physical and psychological aspects. In addition to proper medical treatments, healthcare providers should use a multidisciplinary team approach to resolve the patients’ psychosocial issues, which in turn, may increase the patients’ quality of life. Self-care education may be necessary to help the patients manage the condition and decrease the number of medications. Keywords: Mental health, Quality of life, SLE, Thailand
