Mycotoxins often contaminate cattle food, which can cause liver damage, immunosuppression, and reduced milk production. Although previous studies have shown the benefits of adsorbents in farm animals, knowledge regarding their mechanism of action is limited, especially when intoxication occurs due to naturally contaminated diets. The present study aimed to assess whether the daily oral administration of mycotoxin adsorbent bentonite clay based on aluminosilicate for 56 days, would attenuate these changes in 18 dairy cows, which were multiparous in the middle of the lactation stage, and were consuming a diet containing fumonisin B1 and B2, zearalenone, and desoxynivalenol. The animals were divided into treatment (TG, n = 9) and control (CG, n = 9) groups, and subjected to assessment of liver functions, hematological assessments, assessment of oxidative leucocyte metabolism by the tetrazolium nitroazul (NBT) technique, and physical chemical analysis of milk, every week for two months, totaling eight analyses. It was observed that the use of the adsorbent caused a reduction in the milk excretion of aflatoxin M1 (AFM1), an increase in levels of serum protein (p = 0.03) and albumin (p = 0.0001), an increase in leukocyte oxidative metabolism from day 24 of treatment(p = 0.05), and increased milk production from the day 16 of treatment (p = 0.08). There was no improvement in the physicochemical indices of the milk. It was concluded that the use of an aluminosilicate-based adsorbent was able to attenuate the effects of mycotoxins on the function of leukocytes and increase milk production.

Introduction: Breastfeeding is the adaptation process experienced by postpartum mothers. If she has assisted carlier in breastfeeding, the mothers will succeed to continue breastfeeding. In reality milk ejection very little on the fi rst daysafter birth is a constraint in early breastfeeding. Acupressure points for lactation can increase milk production, help maximize prolactin and oxytocin receptors and minimize the side effects of delaying in the breastfeeding process. The objective of this study was to prove the difference effect of Acupressure Points for lactation and oxytocin massage to increase milk production and comfort on postpartum mothers. Method: This study used a quasy-experiment design with pre-post test design with control group. The sample of this study was recruited using consecutive sampling, consist of 27 mother postpartum primiparous, divided into 3 groups. Comfort was measured with GCQ, and milk production measured with Weighing Test. Data measured before and after the intervention, and analyzed by ANOVA with α = 0.05.Results: The results showed there was a signifi cant difference in comfort between the Acupressure Points for Lactation, oxytocin massage and control group (p = 0.035). and there was a a signifi cant difference in milk production between the Acupressure Points for Lactation, oxytocin massage and Control group (p = 0013). Analysis and Discussion: Conclusion, Acupressure Points for Lactation effective to increase comfort and milk production in postpartum mothers in Kediri District Hospital. This technique should be used as an alternative intervention in treatment of postpartum mothers. Nurses need to teach these techniques to postpartum mothers to be more independent in reduxing the problem of lactation.Keywords: acupressure points for lactation, comfort, Milk Production

Hypophysectomy of the rat renders this animal deficient in the hormones of the anterior pituitary gland, thus causing many primary and secondary hormonal effects on basic liver functions. Biochemical studies of these alterations in the rat liver cell are quite extensive; however, relatively few morphological observations on such cells have been recorded. Because the available biochemical information was derived mostly from disrupted and fractionated liver cells, it seemed desirable to examine the problem with the techniques of electron microscopy in order to see what changes are apparent in the intact liver cell after hypophysectomy. Accordingly, liver cells from rats which had been hypophysectomized 5-120 days before sacrifice were studied. Sham-operated rats served as controls and both hypophysectomized and control rats were fasted 15 hours before sacrifice.

Moisture desorption observations from two bentonite clay mats subjected to ten environmental zones with individually different combinations of laboratory-controlled constant temperatures (between 20 °C and 40 °C) and relative humidity (between 15% and 70%) are presented. These laboratory observations are compared with predictions from mathematical models, such as thin-layer drying equations and kinetic drying models proposed by Page, Wang and Singh, and Henderson and Pabis. The quality of fit of these models is assessed using standard error (SE) of estimate, relative percent of error, and coefficient of correlation. The Page model was found to better predict the drying kinetics of the bentonite clay mats for the simulated tropical climates. Critical study on the drying constant and moisture diffusion coefficient helps to assess the efficacy of a polymer to retain moisture and control desorption through water molecule bonding. This is further substantiated with the Guggenheim–Anderson–De Boer (GAB) desorption isotherm model which is presented.

AbstractAs future climate challenges become increasingly evident, enhancing performance resilience of farm animals may contribute to mitigation against adverse weather and seasonal variation, and underpin livestock farming sustainability. In the present study, we develop novel seasonal resilience phenotypes reflecting milk production changes to fluctuating weather. We evaluate the impact of calendar season (autumn, winter and spring) on animal performance resilience by analysing 420,534 milk records of 36,908 milking ewes of the Chios breed together with relevant meteorological data from eastern Mediterranean. We reveal substantial seasonal effects on resilience and significant heritable trait variation (h2 = 0.03–0.17). Resilience to cold weather (10 °C) of animals that start producing milk in spring was under different genetic control compared to autumn and winter as exemplified by negative genetic correlations (− 0.09 to − 0.27). Animal resilience to hot weather (25 °C) was partially under the same genetic control with genetic correlations between seasons ranging from 0.43 to 0.86. We report both favourable and antagonistic associations between animal resilience and lifetime milk production, depending on calendar season and the desirable direction of genetic selection. Concluding, we emphasise on seasonal adaptation of animals to climate and the need to incorporate the novel seasonal traits in future selective breeding programmes.

Transarterial chemoembolization (TACE) is usually followed by hepatic dysfunction. We evaluated the effects of L-carnitine on post-TACE impaired liver functions.Methods. 53 cirrhotic hepatocellular carcinoma patients at Osaka Medical College were enrolled in this study and assigned into either L-carnitine group receiving 600 mg oral L-carnitine daily or control group. Liver functions were evaluated at pre-TACE and 1, 4, and 12 weeks after TACE.Results. The L-carnitine group maintained Child-Pugh (CP) score at 1 week after TACE and exhibited significant improvement at 4 weeks after TACE (P<0.01). Conversely, the control group reported a significant CP score deterioration at 1 week (P<0.05) and 12 weeks after TACE (P<0.05). L-carnitine suppressed serum albumin deterioration at 1 week after TACE. There were significant differences between L-carnitine and control groups regarding mean serum albumin changes from baseline to 1 week (P<0.05) and 4 weeks after TACE (P<0.05). L-carnitine caused prothrombin time improvement from baseline to 1, 4 (P<0.05), and 12 weeks after TACE. Total bilirubin mean changes from baseline to 1 week after TACE exhibited significant differences between L-carnitine and control groups (P<0.05). The hepatoprotective effects of L-carnitine were enhanced by branched chain amino acids combination.Conclusion. L-carnitine maintained and improved liver functions after TACE.

A desirable option for increasing milk yield per farm is to increase milk production in summer without compromising peak-season production or the duration of lactation. The dairy industry has a goal to achieve a 4% per month post-peak decline of milk production. The effect of five pasture types and two summer water regimes on predicted farm milk yield, in Northland, Waikato, Manawatu and Canterbury was measured over 1 year. Two pasture treatments, resident pasture and Grasslands Nui ryegrass, were common to all sites. A third pasture treatment varied between sites: triple mix (Grasslands Advance tall fescue, Grasslands Kara cocksfoot, and Grasslands Maru phalaris) at the Manawatu site; the same triple mix but with Grasslands Raki paspalum at the Northland site; and low-endophyte ryegrass and Grasslands Kahu timothy (LER) at the Canterbury site; all sown treatments included red and white clover. All five pasture types were included at the Waikato site. On average for all pasture types, water deficit reduced summer herbage accumulation (HA) to 79, 68, 43 and 18% of irrigated controls, and annual HA to 88, 80, 73 and 63% of irrigated controls in Northland, Waikato, Manawatu and Canterbury, respectively. Since farm milk yield predicted by UDDER was highly correlated with annual HA (R2 = 83%), the effects of pasture type and water deficit on milk yield were similar to effects on HA. Seasonal and annual HA differed among the five pasture types at each of the four sites. The most important factor affecting predicted farm milk yield was annual HA, with relatively little effect from the seasonal pattern of pasture growth. Differences in shapes of the predicted milk supply curves for various treatments occurred, particularly when drought forced early drying-off. The best predicted summer milk yield was for the Canterbury irrigated LER pasture treatment, a 6.8% per month postpeak decline of milk production.

Abstract Adequacy of milk production in the newborns will affect the success of exclusive breastfeeding. Not all postpartum mothers are able to increase milk production in the postpartum period. Acupressure at the meridian points is one way to increase milk production in postpartum mothers. This study aims to determine the effect of acupressure therapy on increasing breast milk production in postpartum mothers at PKU Muhamadiyah Bantul. This study was a quantitative study  a quasi-experimental research design with pre-test and post-test nonequivalent control group. The number of respondents in each group was 17 people. The treatment given was acupressure at the meridian points for 5 minutes on days 2 and 3of poatpartum. Breastfeeding adequacy was assessed before treatment and on day 4 postpartum. Data were analyzed by Mc Nemar analysis. The results showed that there was a significant difference in breast milk production before and after acupressure with p value of 0.000 (p value <0.05). There was a significant difference in breast milk production in the control group before and after being given the breastfeeding technique leaflet p value 0.001 (p value <0.05). Conclusion: There is no significant difference in breast milk production after being given acupressure and after being given leaflets about breastfeeding techniques at PKU Muhamadiyah Bantul p value 0.100 (p value> 0.05).  Keywords: acupressure, breast milk production, postpartum

Relevance. Dagestan Republic in terms of natural and climatic characteristics is the most favorable for the of ixodid ticks - carriers of pathogens of blood-parasitic diseases of farm animals. In this regard, further improvement of the set of scientifically grounded control measures and the search for new promising chemotherapeutic drugs of the prevention and treatment of pyroplasmidosis of cattle are major problem of great national economic importance.Materials and methods. The studies were carried out in farms, unfavorable on pyroplasmidosis, in the conditions of Dagestan Republic. The object of the study was cattle, spontaneously invaded by various types of blood parasites. Experеmental and control groups in production experiments were selected according to the principle of analogues. In the first control group (n = 10) the drug was not used. The second (n = 10) was injected with the drug DAC 5% at a dose of 1 ml/20 kg (DV 2.5 mg/kg), intramuscularly, at the rate 5 ml per 100 kg of live weight. The animals of the third (n = 10) were injected with the injectable preparation forticarb 10% at a dose of 4 ml/100 kg (DV 4 mg/kg) of live weight, intramuscularly, once.Results. It was found that with a single intramuscular injection of forticarb at the rate 2 ml/50 kg of live weight, the temperature and parasitic reaction in the body of sick animals decreased in a very short time. Therapeutic efficacy in pyroplasmidosis of cattle was 90%.
