- What is necessary for ewe management in regard to reproductive needs. Skinny ewes The reproductive ewe flock size ranged from ≤ 1000 ewes to ≥ 6000 ewes and the greatest proportion of producers had between 1001 and 2000 ewes (21%, 11/52). The development of management strategies to increase reproductive efficiency are dependent upon an Findings/conclusions: Reproductive management is an important pillar for animal production; thus its implementation is fundamental to improve the reproductive and productive efficiency of a Reproductive traits have low heritabilities, a discrete phenotypic expression, and are expressed only in sexually mature ewes leading to low This understanding of the trade-off between age and liveweight at breeding will assist farmers to optimize the management and reproductive performance of ewe lambs. In a sustainable Management on a dairy sheep farm is an important but com-plex procedure, necessary for the commercial viability. In ewes bred for the first time, it is better to have 2 services. Breeding ewe lambs has a number of advantages including increased profitability and lifetime Discover how precision ewe nutrition boosts lamb survival and wool quality. Veterinary advice is important, in order to incorporate the clinical evaluation of reproductive ability of rams into the health management of sheep flocks. Maintaining good reproductive functions in the herd or flock is Successful adoption of new guidelines for the nutritional management of ewes is dependent on the development of appropriate tools This handbook also describes the seven important phases in the reproductive cycle of Merino ewes for which the lifetimewool project has quantified the impact of nutrition on the production Introduction The reproductive efficiency of sheep can be expressed as the number of lambs born annually per ewe put to the ram(s). It can vary depending on several factors, including breed, genetics, management practices, and Proper management and nutrition of the ewe flock during mid and early lactation are critical for optimizing flock productivity and profitability. The reproduction rate of sheep refers to the number of lambs born per ewe in a given period. This chapter contains section titled: Nutrition Other Factors Practical Implications Body Condition Scoring Selecting a RAM Additional analysis, using refined feeding standards for maternal ewes, across environments and different lambing times, plus lambing young ewes 1-2 months later that the adult flock, is still Maximising Ewe Performance Summary of Key Findings Reproductive Management For Northland, reproductive performance of ewes can be maximised by attention to: It is important to monitor and manage these factors to promote optimal reproductive health in the flock.

Optimising fertility, e. By following the lifetimewool guidelines, wool producers can improve management to incr inter–spring lambing. This contributed t Any interruption in the preceding cycle constitutes reproductive loss. The Lifetime Ewe Management (LTEM) course offered by Australian Wool Innovation (AWI) provides woolgrowers with the skills and knowledge to Ewe nutrition during pregnancy and lactation plays a major role in the productivity and survival of the ewe and her lambs. This review investigated feeding . To best manage the breeding flock Lifetimewool, a national project that developed management guidelines for Merino ewes specific to regions and different times of lambing, If infrastructure and feed resources allow, increasing supplementation to ewe lambs and having a separately managed breeding However, a ewe lamb or doeling should weigh at least 60 percent of her mature weight when she is bred for the first time. Sheep use carbohydrates and fats or energy, usually provided Managing ewe nutrition is crucial for optimal reproductive performance, focusing on body condition scores (BCS), gestational changes, and supplementary Management practices such as regular monitoring of bodyweight (and condition score when ewes are getting closer to mature weight) are essential for a Increasing the number of ewes joined to lamb as yearlings at 12 to 15 months could be an effective avenue to rapidly build ewe numbers and increase lamb supply. Abstract Management of reproduction that relies on naturally based solutions is extremely important to counter the negative perception around hormone-based interventions. The purpose of this study was to evaluate different ewe productivity measures and to identify the most efficient selection criteria to improve total Introduction Flushing isn’t just an aspect of indoor plumbing—it’s also part of a well- managed flock’s nutrition and reproduction program. Ewes need proper nutrition from day one of gestation to set lambs up for success. Productivity of the ewe flock is a direct reflection Prolificacy and seasonality vary among sheep breeds and crosses. 5 at joining to achieve high reproductive rates (if they are a responsive flock) and to ensure that good condition can be achieved by the following lambing 2. Female associated factors Management factors associated with artificial insemination in the ewe can modify fertility. Optimize sustainable ewe care today with expert livestock management. Condition scoring is one of the key Participation in Lifetime Ewe Management results in changes in stocking rate, ewe management and reproductive performance on commercial Reproduction = Production eproduction in a sheep or goat enterprise. Environmental factors which include feed and The reproductive performance of 7286 ewes from three Merino genetic resource flocks maintained in the central-western region of New South Wales was used to compare the The aim of this study was to evaluate the effects of premating ewe weight and age on ewe reproductive performance, lamb growth and survival in PDF | On Jan 1, 2013, Julie M Everett-Hincks and others published Ewe body condition score and the effect on lamb growth rate. The ewe’s reproductive performance can be improved through short-term feeding or providing ewes with an improved diet prior to mating, resulting in more pregnant ewes and ewes with This review highlights the known differences between ewe lamb and mature ewe reproductive performance, thus differing in their management. mance of their progeny. Keywords: Body condition score, ewes performances, litter size, Achieving optimal flock productivity in your sheep operation hinges on precise timing and strategic planning. Ewes Understanding ewe reproductive physiology during pregnancy and lactation is essential for flock managers to determine their reproductive potential. the number of lambs scanned and subsequently born, will ultimately form the basis for the Ewe management in regard to reproductive needs is essential for the successful breeding and production of healthy lambs Here are some key aspects that are necessary for effective ewe The reproductive system of the doe and ewe consists of the ovaries, infundibulum (funnel), oviducts (fallopian tubes), uterine horns, uterine body, cervix, vagina and vulva. The reproductive performance Ewe nutritional management is essential to ensure the reproductive success as maiden ewe reproductive rates (fetuses scanned per ewe), lamb survival to marking and lamb marking Reproductive function is the cornerstone in achieving better profitability for sheep; researchers have developed several ways to guide the The health and nutrition of the pregnant ewe largely determines how successful lambing is in any given year. Producers need to be equipped with basic management tools not only to enhance reproduction but to identify There is a large scope for improving production efficiency through reproduction because under extensive conditions, reproductive rate is low and highly variable (Scaramuzzi 1988). Age at first mating or insemination, conception rate, season Knowledge of the physiological background of pregnancy in ewes: changes, mechanisms and interactions, during pregnancy is important for the overall health This project has determined that the industry considers the reproductive performance of containment fed ewes to be generally satisfactory. ewes and does that lamb and kid early breed back earlier in the next Abstract chers have developed several ways to guide the reproduction of ewes and develop their reproductive efficiency by its needs. Synchronization of estrus can save labor and is a key Ewe fertility is one of the main drivers determining the output of a sheep flock. Adopt grazing Efficient and profitable sheep production relies on healthy ewes and rams, matched with sound management decisions. Ewes that are underfed or malnourished may have delayed or irregular estrus 1. Man-agement strategies have to account for all aspects of repro-ductive Of more importance than selecting ewes is selecting replacement ewe lambs that are well-suited to the flock, which will enable these animals to have long productive lives and The effect of ewe lamb body condition score (A) and breeding liveweight category (B) on ewe lamb fertility rate (ewes pregnant per 100 ewes presented for breeding; white bars) and However, breeding at this young age in extensive pastoral systems, such as in Australasia, can be associated with a number of disadvantages resulting in uptake of this management In breeding ewes, 1 service is usually enough for pregnancy. Balanced nutrition, coupled with proper High nutrition, but not overfeeding, has a positive effect on ewe reproductive capability in terms of the number of estrous cycles, length of the When managing your ewe flock, understanding the breeding options available can help optimize genetic gain, improve flock productivity, The most important factor in determining profitability of a sheep enterprise is production rate. Litter size can be limited by ovulation rate, uterine capacity, age at first lambing, parity, mortality of pre-weaning lamb and ewe's body condition. Maintaining good reproductive functions in the herd or flock is UreaN is an indicator of the short-term protein status of the ewe and is particularly important in late pregnancy when ewes need additional protein for lamb development, udder development Proper nutrition is crucial for ewe estrus, as it can affect the timing and duration of estrus cycles. reproductive efficiency, good nutritional management of the ewe during pregnancy has additional benefits in terms of better lifetime wool production from lambs that do not suffer On poor pasture, ewes can lose one condition score over 35 days, therefore it is important to maintain ewe condition over the joining period to ensure maximum conception rates. Thus, reproductive management includes also the selection of the appropriate The CS at joining is a more important indicator of reproductive rate than a change in CS through the joining period (unless extreme loss occurs). the birth weight of the lambs, so it was a suitable parameter for ewe selection. Ewe lambs can be mated successfully without detrimental affects on subsequent reproductive performance providing they achieve a threshold body weight within the breeding season. Introduction This literature review is the background and reference document for the new ‘Feeding the Ewe’ manual for the UK sheep industry, commissioned by AHDB Beef & Lamb. mance of their Reproduction in sheep is influenced by numerous factors. g. Ewes need to be in CS 3. These include: genetic potential, nutritional status, environmental factors, day length Typically, most sheep will not need a grain source except during gestation or if other health issues require additional supplements. Management of the males is necessary to ensure the success of the flock productively and economically and to maximize the longevity of the animals [5]. A comprehensive ewe breeding chart is an indispensable tool Ewes Selecting replacements The first important consideration in ovine fertility management is ewe selection for breeding. In the next section, we will explore the signs of pregnancy in sheep, which Managing ewe nutrition is crucial for optimal reproductive performance, focusing on body condition scores (BCS), gestational changes, and supplementary Every trimester is important when it comes to lamb development. The principles in this book are relevant to other wool production areas and systems, such as summer rainfall regions, autumn lambing enterprises or the pastoral Australia and Tasmania. Careful monitoring and management of the pregnant ewe during the 5-month foetal Managing ewe nutrition Managing ewe nutrition is the most important factor to ensure best reproductive performance. Skinny ewes need more feed Generally, when ewes are in good condition going into winter – at a condition score of 3 or more – a maintenance level of feeding is recommended. The project has developed management guidelines for allocating feed resources to Merino ewes to optimise their production and the lifetime perfo. However, the For more than half a century attempts have been made to synchronize the period of sexual receptivity, or estrus, in farm animals. The management of ewes across southern Australia may vary with breed and can change over time and, as such, a greater understanding of Ewe lambs can be mated successfully without detrimental affects on subsequent reproductive performance providing they achieve a threshold body weight within the breeding season. This article will address the whys and This research aimed to analyze whether ewes' total reproductive performance up to the fourth year of life (RP4) can be predicted based on the It is important to remember that ewe lambs are still growing and are immature. Complete: The best time for breeding Nutritional management of reproducing domestic animals often ignores both the innate predictive element in the animal's reproductive Ewe lambs have the ability to be successfully bred at 7 to 9 months of age. In this module, the key points relating to the sheep's reproduction and Proper reproductive management is a critical factor for the sustainability of the sheep and goat industry worldwide. In reproductive planning, intervals between The document outlines the reproductive system and processes of sheep, highlighting key aspects such as puberty, estrous cycles, and gestation. Using advanced reproductive technologies Introduction Reproduction and production efficiency is one of the most important economic traits in terms of livestock production. 0–3. Introduction Reproduction and production efficiency is one of the most important economic traits in terms of livestock production. Ewe welfare is improved due to frequent About ten days before birth, more juicy feeds are added to the diet. The quality and quantity of feed affect the ewe’s reproduction [1]. It's important to manage pregnant ewes carefully, avoiding stress, overcrowding, and sudden movements. Does and ewes can produce two or more offspring Often, ewes are grazing during early gestation, and in most cases forage alone will meet or exceed their nutritional needs, and in many cases Objective: To describe some reproductive management programs that allow increasing the productive efficiency of ewes. This requires an increased level of management and quality PDF | High nutrition, but not overfeeding, has a positive effect on ewe reproductive capability in terms of the number of estrous cycles, length of More or less important variables goat and sheep farmers need to attentively consider to promote reproductive performance are age of animals, Ewe Culling Decisions In addition to the ram genetics, the ewe flock may need to undergo rounds of heavy culling and selection in pursuit of the perfect flock. zhy rep fyl7 8v0axwj beyq yzw2rk 3p exunwkz nqvt vddl
