Heat stress negatively impacts dairy cows in several ways: it causes their body temperature to rise, reducing their feed intake and milk production. Studies show that heat stress can decrease milk yield by around 45%, with reduced feed intake only accounting for about half of the lost production. Pair-feeding trials indicate there are also direct metabolic effects of heat stress beyond just lower nutrient intake. Reducing heat stress can help minimize its economic impacts on dairy farms and the dairy industry.

Cooling Strategies During Heat Stress- HansenDAIReXNET
1) Cooling cows effectively during heat stress involves reducing solar radiation exposure, increasing evaporative heat loss through the use of sprinklers and fans.
2) Evaporative cooling through sprinklers is most effective at lowering body temperature when humidity is high, though tunnel ventilation may not work better than freestall barns.
3) It is important to cool not just lactating cows but also dry cows, calves, and growing heifers to prevent rises in body temperature that can impact fertility, growth rates, and milk production. Body temperature measurements should be used to assess heat stress levels.

1. The study tested whether maternal stress affects offspring recombination rates and the relationship between fitness and recombination in a host-pathogen system.
2. The results showed that maternal exposure to live or heat-killed pathogens did not affect offspring reproductive output but did influence offspring recombination rates in some treatment groups.
3. No correlation was found between recombination rates and reproductive output, suggesting fitness-associated recombination may be rare in this system. Maternal stress effects can have complex consequences on offspring stress response and genetic variation between generations.
The study assessed the effects of multiple stresses (thermal, nutritional, and walking stress) on reproductive performance in Malpura ewes. Ewes were divided into two groups - a control group (GI) sheltered in a shed and a stressed group (GII) exposed to average temperatures of 42°C and made to walk 14km daily. GII ewes had lower estrus rates, shorter estrus duration, lower conception and lambing rates compared to GI ewes. Hormone levels also differed between the groups. The study demonstrated the detrimental impacts of multiple concurrent stresses on reproductive parameters in Malpura ewes.

Dr. Jeff Vallet - The Importance Of Nutrition During Gilt DevelopmentJohn Blue
This document summarizes research on developing diets to slow growth and alter body composition in gilts. It found that:
1) Lowering dietary lysine levels can reduce gilt growth rates while keeping energy levels constant, without affecting fat-to-lean ratios.
2) Lower lysine diets increased age at puberty but did not affect the percentage of gilts pubertal by 220 days.
3) While diets can manipulate backfat levels, it is difficult to substantially alter fat composition through ad libitum feeding alone.
4) The research developed suitable diets for a larger upcoming trial examining the effects of slower gilt growth on subsequent sow performance and mammary gland function.

Effects of restricted feeding, low energy diet, and implantationNia Nia
This document describes a study that examined the effects of restricted feeding, a low-energy diet, and implantation of trenbolone acetate plus estradiol on growth, carcass traits, and circulating concentrations of insulin-like growth factor (IGF)-I and IGF-binding protein-3 in finishing barrows. Sixty-four barrows were divided into groups subjected to different feeding regimens, diets, and implantation. Blood samples were taken every 3 weeks and animals were slaughtered at approximately 105 kg. Restricted feeding decreased average daily gain, the low-energy diet reduced backfat thickness but decreased feed efficiency, and implantation decreased average daily gain, feed intake and backfat thickness while increasing feed efficiency.

This study examined the effects of doubling the egg turning rate during incubation on gut development in chick embryos. Eggs were incubated under normal conditions, with one group turned at the standard rate and another turned twice as often. At 18 days, embryo and gut tissue samples were collected and analyzed. The doubled turning rate did not significantly impact embryo weight, small intestine weight or length, villus number or length. While some measures tended to differ between groups, none reached statistical significance. It was concluded that doubling the egg turning rate during incubation did not significantly alter gut development in chick embryos by day 18.

Area Regional Control (ARC) began as a coordinated effort between producers and veterinarians to eliminate PRRS virus in discrete regions. While objectives have evolved to disease control rather than elimination, the ARC framework has proven successful by establishing communication, collaboration, and coordination among producers. This is evidenced by the expansion of ARC projects, inclusion of allied industry partners, application to other diseases like PEDv, and growth of informal producer information networks seeking to share updates on disease statuses and potential routes of spread.

The study analyzed records of 17,787 Holstein cows from 1999 to 2004 to investigate the effects of environmental factors on abortion rates and offspring sex ratios. The overall abortion mean was 5.80% and was significantly affected by season and year of calving, with higher rates in spring and summer. The overall offspring sex ratio mean was 51.05% male. Year of conception and calving interval significantly affected sex ratio, with ratios skewed in some years and intervals. The document provides background on abortion and sex ratio in cattle before presenting results of the statistical analysis of the data, which found some environmental factors had significant impacts on the two traits studied.

Thermoregulation responses of broiler chickens to humiditybabuvet
This document summarizes two experiments that investigated the effect of relative humidity (RH) at 35%, 60%, and 85% on thermoregulation responses in 4-week old broiler chickens exposed to high (35°C) and mild (30°C) ambient temperatures. The experiments measured rectal temperature (RT), plumage temperature at back (PBAT), and skin temperature at breast (SBRT) at various time points over 24 hours of exposure. The results showed that RH had a significant effect on RT at 35°C but not 30°C, and peripheral temperatures were significantly affected by RH but responded differently depending on ambient temperature. High RH above 60% impaired heat transmission from core to periphery at 35°
In the tropical climate like India, the high ambient temperature along with high humidity is the major stressor (abiotic), thus resulting in the HEAT STRESS a major concern of poultry production.

65°F – 75°F Ideal temperature zone
75°F – 85°F A slight reduction in feed consumption
85°F – 90°F Feed consumption falls further, cooling should be started before this temp is reached.
90°F - 95°F Feed consumption continues to drop, danger of heat prostration among layers, cooling .
95°F-100°F Heat prostration, water consumption is high.
>100°F Emergency measures must be taken, survival is concern at these temperatures.
CONCEPTS AND STRATEGIES TO AMELIORATE THE HEAT STRESS
1. Environmental strategies
Intermittent Photoschedule(light).
2. Housing management
Sites election, design and construction, ventilation, internal and roof cooling, Density of birds.
3. Nutritional strategies
Increasing energy density
Dietary Protein level and Amino acid composition
Vitamins – A,C,E.
Minerals.
Non nutrient feed additives.
Water and electrolyte balance.
4. Feeding strategies
Early feeding
Intermittent feeding
Sex separate feeding
Fasting or feed with drawl.
5. Genetic strategies
Selection for heat tolerance.
Selection for disease resistance.
Use of major genes – Naked neck(Na), Frizzle(F), Dwarf(dw), Silky (h), Slow feathering (K).
ENVIRONMENT STRATEGIES:
A). Intermittent Photo schedule
An intermittent light regime can improve the feed efficiency and thus the broiler production efficiency, by decreasing the fat deposition associated with increased incidence of leg abnormalities, metabolic and cardiovascular diseases, ascites.
The favourable effect is related to the lower heat production during both light and dark period, although fluctuations in heat production are following closely the light-dark alternation.
This photo schedule contains more than one scotophase and one darkphase which recur at 24 hr intervals.
This regime increases the feed consumption during cooler part of the day.
Symmetric - when scotophase and dark phase are of equal length.
Asymmetric - when they are not in equal length.
3weeks age of broiler raised under 2L:4D intermittent light regime were significantly lighter than broilers raised in continuous light schedule but at 7 weeks it is reverse.(Proudfoot, 1975).
The initial reduction in body weight gain of birds under intermittent schedule is followed by compensatory growth, but the compensatory growth depends on genotype and sex.
Boschouwers and Nicaise (1992) observed that physical activity in broilers were lowest under 100Hz fluoroscent light and highest under incandescent.
HOUSING MANAGEMENT
Orientation : east west to reduce direct solar radiation
Shade of trees and green crops around the houses will prevent direct heating, .vegetation should be mowed frequently so that it doesnot obstruct air flow
Houses should be oriented perpendicular to wind direction for max
This study evaluated the effects of early heat acclimation (EHA), and different periods of feed restriction (FR) on broiler performance under chronic heat stress. 480 broiler chicks were subjected to control, EHA, or FR for 4 or 6 hours daily from days 8-14, 8-21, or 8-28. Results showed that EHA and longer FR periods improved body weight, weight gain, and feed conversion compared to control, with FR from 8-28 days performing best. Mortality rate was lowest in birds subjected to EHA and longer FR. In conclusion, EHA and feed restriction can help mitigate the negative impacts of heat stress on broiler growth and welfare.
The impact of heat stress on fertility and milk productionbuzzcp
This document summarizes the impact of heat stress on dairy cow fertility and milk production based on research conducted in Israel. Some key points:
- Heat stress reduces dairy cow fertility by decreasing estrus intensity and disrupting follicle development, oocyte competence, embryo development, and progesterone secretion.
- Cooling cows using shade, fans, sprinklers and frequent misting can help prevent declines in milk production during heat stress, but does not eliminate reductions in reproduction.
- Additional strategies like follicle aspiration to induce follicular turnover and progesterone supplementation may help improve summer fertility. A large-scale Israeli study found intensive cooling (10 periods per day) significantly improved conception rates compared to minimal or moderate cooling.
This document discusses diagnosis and treatment of metritis in dairy cows. It provides details on several studies that examined the impacts of metritis including lower dry matter intake before and after calving, associations with specific bacteria and virulence factors, and negative effects on milk production and reproduction. The document also summarizes research on treatments for metritis, finding that systemic antibiotics like ceftiofur and ampicillin effectively resolve clinical signs in the majority of cases but do not consistently improve pregnancy rates. Non-antibiotic intrauterine treatments with povidone-iodine or a uterotonic fluid showed promise based on one recent study.
This document discusses ways to improve the definition of productive life (PL) by considering longer lactations and calf value. It analyzes data from over 1 million Holsteins to estimate heritabilities and correlations for different PL definitions. Key results include:
- PL heritability was highest at 0.073 when considering unlimited lactation length or adding calf value credits
- Genetic correlations between early measures of PL and first-parity protein yield have declined rapidly over time
- The proposed method credits longer lactations and gives higher weights to later parities to better capture an animal's total productive lifetime.

This document summarizes the results of a clinical audit comparing outcomes of 706 embryos that were either vitrified or slow-frozen for fertility treatment. The audit found statistically significant improvements in survival rate, pregnancy rate per embryo thawed, clinical pregnancy rate per embryo thawed, and implantation rate per embryo thawed for embryos that were vitrified compared to those that were slow-frozen after adjusting for patient age differences between the groups. The conclusion is that vitrification led to highly significant improvements in all outcome measures compared to slow-freezing based on this retrospective analysis of data.
This document discusses several topics related to estimating heritability and genetic parameters in livestock populations, including:
1) Factors that can affect heritability estimates such as population, location, method of estimation, and data set size.
2) Methods for estimating heritability including paternal half-sib analysis, repeatability, and genetic and phenotypic correlations.
3) The relationship between heritability, repeatability, and variance components.
4) Software tools that are commonly used for genetic data handling and analysis, including LSMLMW and DFREML.
Incubation Latest Findings And Ideas 2008guest319df2
The document discusses factors that affect embryo temperature during incubation. It finds that machine temperature does not equal embryo temperature, as embryo temperature depends on a balance between heat production and heat loss. Heat production is influenced by developmental stage, physical traits, biological traits like breed and egg size, and environmental factors like oxygen levels. Heat loss depends on evaporation, which is affected by humidity and air temperature, and heat transfer, which depends on temperature differences, air properties, and velocity. Maintaining a constant eggshell temperature close to 37.8°C is important for optimal embryo development.
Effect of early age thermal challenge on growth performance, haematological p...Innspub Net
This study aimed to evaluate the effect of thermal stress on haematological profile and carcass yield of guinea fowl (GF). A total of 180 one-day old GF keets were assigned to 3 treatments, having 4 replicates of 15 birds each. The treatments were: control (T1); mild heat stress for 6h/day (T2), and high heat stress for 8h/day (T3). Data were collected on weekly body weights, feed intake and feed conversion ratio of the birds. At 6-weeks old, blood samples were collected from 8 GF for determination of haematological profile. At 14-weeks old, 8 birds were also slaughtered per treatment to evaluate relative organ weights, carcass characteristics and immune response. Results showed that the body weight gain and feed intake of the birds of T1 and T2 were similar and significantly higher than that of T3 at week 1 of age. The FCR of the birds in T1 and T2 were also better at this stage. Lymphocyte counts were higher (p<0.01) in the birds of T2 (95 103/mL) than those of the control (93.33 103/mL) and T3 (93.33 103/mL). The weights of lymphoid organs of T2 and T3 birds were higher (p<0.05) than those of the control group. It was concluded that exposure of keets to heat stress for 8h/day had adverse effects on growth performance at the early age but this effect faded with age. The thermal manipulation in this study didn’t influence the carcass yield but improved the weights of lymphoid organs of indigenous GF, indicating a better thermo-tolerance.

Breast cancer: Post menopausal endocrine therapyDr. Sumit KUMAR
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.

PGx Analysis in VarSeq: A User’s PerspectiveGolden Helix
Since our release of the PGx capabilities in VarSeq, we’ve had a few months to gather some insights from various use cases. Some users approach PGx workflows by means of array genotyping or what seems to be a growing trend of adding the star allele calling to the existing NGS pipeline for whole genome data. Luckily, both approaches are supported with the VarSeq software platform. The genotyping method being used will also dictate what the scope of the tertiary analysis will be. For example, are your PGx reports a standalone pipeline or would your lab’s goal be to handle a dual-purpose workflow and report on PGx + Diagnostic findings.
The purpose of this webcast is to:
Discuss and demonstrate the approaches with array and NGS genotyping methods for star allele calling to prep for downstream analysis.
Following genotyping, explore alternative tertiary workflow concepts in VarSeq to handle PGx reporting.
Moreover, we will include insights users will need to consider when validating their PGx workflow for all possible star alleles and options you have for automating your PGx analysis for large number of samples. Please join us for a session dedicated to the application of star allele genotyping and subsequent PGx workflows in our VarSeq software.

Editor's Notes
The GDU is to prepare the gilt to be a sow. As such they must set and meet targets for proportion in heat or mated each week, pregnancy rates, maximum age prior to culling (personal preference is 30d after trying to initiate the HNS), culling percentage which will vary considerably etc. Ability of GDU to prepare gilts physiologically was well established long before they became popular, and the increased need for immunological preparation drove the industry to give GDU serious consideration.
