Piglet health at weaning is compromised due to several stress factors. Following the ban of antibiotic growth promoters new alternatives are required to control these problems. This paper reviews the evidence available for the use of spray dried animal plasma (SDAP) as an alternative to antibiotics in weaning pigs. Data from 75 trials in 43 publications involving over 12,000 piglets (mean values) have been used to calculate the performance responses of piglets according to several factors including SDAP origin, protein source from the control diet being replaced, dose of inclusion, age and weight of the piglets at weaning, sanitary conditions and simultaneous use or not of medication. Although the use of SDAP of all origins results in positive responses, it appears that plasma from porcine origin has the highest efficacy. This could be explained by the specificity of its IgG against porcine pathogens. During the first week post-weaning the response to plasma appears to increase with the inclusion dose, although over the two-week pre-starter period an optimal inclusion level of 4-8% is suggested. SDAP improves feed efficiency more markedly when the piglets are challenged with an experimental infection or when feed does not contain medication, which could be indicative of a lower expenditure of energy and nutrients to build an immune response against the challenge. There is evidence supporting that SDAP IgG and other bioactive substances therein prevent the binding of pathogens to the gut wall and reduce the incidence of diarrhoea in the post-weaning phase. Overall, plasma can be postulated as an excellent alternative to in-feed antimicrobials for piglets in the post-weaning phase.

Animal in dustry in Korea urgently needs the domestic introduction and the industrial a, pp.ication of embryo transfer technique. Namely, this technique can be utilized effectively, as means of the improvement of livestocks, as means of the increase of meat production, as means of substitute for the livestock import, and dissemination of new breed. However, as this technique avaliable in our country is remaining initial stage, we can not make use of the technique industrially unless we make much improvement as follows; induction of superovulation, non-surgical recovery of embryos, synchronization between the estrus such cycles of donor and recipient, non-surgical transfer of embryos, etc. Simultaneously, the basic studies such as harvesting oocytes from ovary, in vitro culture of oocytes, in vitro capacitation of spermatozoa, cloning by culture of blastomeres and transfer of nuclei, sexing embryo, etc. should not be neglected in order to make the technique of embryo transfer more simple and convenient. For the success of these studies, universities, national and public institutes, large scale cattle farms, and small scale cattle farms should cooperate each other. For instance, universities undertake basic researches, and the national and public institutes a, pp.y the results of the researches to animal industry along with cooperation by large scale cattle farms. By the help of the cooperative organizations, the technique relevant to our environment and farm condition may be able to be finalized, and to be a, pp.ied to samll scale cattle farm. Consequently, being served to stimulate animal productivity, this technique can be contributed to the development of livestock industry in Korea.

Indian subcontinent is a rich source of diverse ovine germplasm, and only very few countries have such a large number of breeds with wide genetic diversity. This vast ovine biodiversity in India is being eroded rapidly and more than 50% of sheep breeds are currently under threat. It is noteworthy that the characterization of Indian sheep breeds was last done in the first half of the century since then no recent estimates are available and surveys in majority of the regions/breeds are far from complete. Starting in 1985 National Bureau of Animal Genetic Resources (NBAGR), Karnal, India, therefore, initiated activities aimed at determining the status and compiling information on indigenous farm animals including sheep. This report represents attempts made to date on the basis of field/literature surveys and additional activities on molecular characterization to ascertain their status including distribution, population changes, breed diversities and risk status. The need, mode and mechanisms of conservation are also described. Involvement of several agencies for evaluation, improvement, conservation programmes and recommendations made for effective characterization and conservation of sheep biodiversity are highlighted. This publication would promote action particularly at national level to improve the information base on domestic Indian breeds of sheep and provide input into national domestic sheep diversity conservation policy decisions.

The study was designed to evaluate the seasonal influences on cross-bred cow milk composition and paneer yield in Dhauladhar mountain range of sub-himalayan region. Fifty samples from each season were collected from a herd of $Jersey{\times}Red\;Sindhi{\times}Local$ cross-bred cows during summer (April-June), rainy (July-September) and winter (November-February) and analyzed for fat, total solids (TS) and solids not fat (SNF). Paneer was prepared by curdling milk at $85{\pm}2^{\circ}C$ with 2.5 per cent citric acid solution. Overall mean for fat, TS and SNF content of milk and paneer yield were 4.528, 13.310, 8.754 and 15.218 per cent respectively. SNF and TS content varied among seasons being highest in winter (8.983% and 13.639%) followed by summer (8.835% and 13.403%) and lowest in rainy season (8.444% and 12.888%). Paneer yield was lowest (14.792%) in rainy season and highest (15.501%) in winter season.

First lactation records of 683 Murrah buffaloes maintained at NDRI, Karnal which were progeny of 84 sires used for comparing the heritability estimates of age at first calving, first lactation milk yield and first service period under single and multiple trait models using restricted maximum likelihood (REML) method of estimation under an individual animal model. The results indicated that the heritability estimates may vary under single and multiple trait models depending upon the magnitude of genetic and environmental correlation among the traits being considered. Therefore, a single or multiple trait model is recommended for estimation of variance components depending upon the goal of breeding programme. However, there may not be any advantage of considering a trait with zero or near zero heritability and having no or very low genetic correlation with other traits in the model. Lower heritability estimates of part lactation yield (120-day milk yield) implied that there may not be any advantage of considering this trait in place of actual 305-day milk yield, whereas, comparable heritability estimates of predicted 305-day milk yield suggested that it could be used for sire evaluation to reduce the cost of milk recording under field conditions.

Reproductive data, such as numbers of days to the first estrus and A.I. service postpartum, number of days to conception, number of A.I. services required for conception, interval between the first estrus and first A.I. service and the average interval of A.I. service in Thai native-Friesian crossbred and pure Friesian dairy cows, were compiled in the National Dairy Training and Applied Research Institute in Chiang Mai, Thailand. The data were analyzed statistically and the effect of milk production on these reproductive traits was investigated. The reproductive efficiency of purebred cows was obviously inferior when compared with crossbred animals, in spite of special care being given to the purebred only in order to alleviate the effect of a tropical climate and provide better feeding. However, the regression analysis between reproductive and lactational parameters revealed a definite antagonistic effect of lactation on reproduction, especially in the purebred cows, which had a larger amount of milk production and longer lactation period. If these effects of lactation were eliminated, there would be no evident difference in reproductive efficiency between purebred and crossbred cows in the conditions of this study. Among the reproductive parameters examined, the number of days to the first estrus and interval between the first estrus and first A.I. service were less affected by breed difference and the magnitude of lactation than other reasons.

Twelve docked and 12 intact Najdi lambs of equal numbers of males and females were slaughtered at 40 kg shorn shrunk body weight, Lipid in all empty body fat components; namely, subcutaneous, intermuscular, intramuscular, omental, mesenteric, channel, perirenal, pericardial, tail, viscera, bone and hide, were determined. Except for ram lambs, which had a lower percentage of lipid in intermuscular partition in loin cut, sex did not influence the relative proportion of subcutaneous or intermuscular fat in each wholesale cut. The data also showed that docking did not change the distribution of lipid in intermuscular and intramuscular fat partitions in each wholesale cut. Docked lambs tended to accumulate lower proportions of the lipid in subcutaneous fat component in the cuts located along the dorsal line than intact lambs. The total amount of lipid deposited in the empty body of ewe lamb was heavier in weight than that of ram lamb. Docking had no effect on the distribution of total lipid in the empty body, except for subcutaneous fat component, being greater in docked lambs than did intact ones. Generally, the highest proportion of fat was associated with subcutaneous depot followed, in order, by intermuscular, mesenteric, tail, intramuscular and omental fat partitions.

The purpose of this study were to analyze the consumption patterns of animal foods during the sixteenth century through Shamirok. There were eleven animal foods : beef, pork, chicken, pheasant, deer, roe, lamb, bear, fox, sparrow, and horse. The most frequently consumed were in the order of pheasant, doe, and chicken. There were 44 fish consumed, including flatfish, hairtail, mackerel, flounder, kumlin fish, bass, null fish, codfish, and red snapper, as well as four mollusks and six shellfish. Eggs and fish egg were also consumed. These foods were cooked as Tang(湯), Gui(灸), Po(脯), Hoe(膾), and Sookyook(熟肉), or processed after being dried or salted. The animal foods were mostly consumed as Po and Tang in daily eating and for formal dishes. Fish were mostly consumed as Jockgal or Shikhae. The foods were primarily acquired by donation from local officials or relatives ; secondly by independent poultry farming, fishing, or hunting, along with the production of grain and thirdly through barter with rice and textiles. Food were sometimes traded for profit, but such acts of trading while living ; as wartime refugees was a meager means for living.

The composition of turmeric powder (TP) can affect the quality properties and storage characteristics of pyeonyuk; however, the appropriate addition level of TP in pyeonyuk has not been established. To address this, an experiment was designed with one control and three TP treatments: control (TP 0%), T1: (TP 0.1%), T2: (TP 0.3%), and T3: (TP 0.5%). All the TP treatments markedly increased protein and ash contents compared to the control. The water holding capacity was equally retained with the control and T3 treatments, but was significantly lower with the T1 and T2 treatments in pyeonyuk (p<0.05). Lightness and redness values were both reduced with the addition of TP, whereas the yellowness value increased. Values for 2-thiobarbituric acid reactive substances and the total microbial count for pyeonyuk with added TP showed an improvement over time. As a result, the addition of TP did not have a significant negative influence on the quality characteristics of the pyeonyuk with addition of 0.5% TP being particularly effective for water retention capacity and inhibition of lipid oxidation.

Probiotic products have long been recognized for their health benefits. Additionally, milk has held a longstanding reputation as a dairy product that offers high-quality proteins and essential micronutrients. As awareness of the impact of food on health grows, interest in functional products such as probiotic dairy products is on the rise. Fermentation, a time-honored technique used to enhance nutritional value and food preservation, has been used for centuries to increase nutritional value and is one of the oldest food processing methods. Historically, fermented dairy products have been used as convenient vehicle for the consumption of probiotics. However, addressing the potential drawbacks of fermentation has recently led to increase in research on probiotic dairy drinks prepared without fermentation. These non-fermented dairy drinks have the advantage of maintaining the original flavors of milk drinks, containing potential health functional probiotics, and being an alternative dairy product that is helpful for probiotics intake. Currently, research on plant-based dairy products is rapidly increasing in the market. These developments might suggest the potential for novel forms of non-fermented dairy beverages with substantial prospects in the food market. This review aims to provide an overview of milk-based dairy beverages, both fermented and non-fermented, and discuss the potential of non-fermented dairy products. This exploration paves the way for innovative approaches to deliver probiotics and nutrition to consumers.
