: Dairy products are an essential source of animal protein, particularly for nutritional vulnerable groups and vegetarians in Asian countries. Therefore, the approach towards increasing the domestic supply of milk is to raise the buffalo milk yield via genetic improvement from the semen of the selected buffalo sire that possesses a high predicted milk difference. Data were collected from Artificial Insemination Centers in Egypt, as a case study, to apply a dynamic mathematical investment model for estimating the rate of return (IRR) to genetic investment. The effective variables in IRR, besides the economic variables, are the reproductive traits and feed efficiency. The estimated most probable level of IRR was feasible, i.e., 19.71%. A worse change in the reproductive efficiency variables, i.e., the aggregate of 10% increase in the number of conception services, age at the First Calving, and the service period, would decrease the IRR by 7.51%. A decrease in feed efficiency by 10% would decrease the IRR by 9%. A worse change by 10% in the feed costs, price of semen, and milk price would decrease IRR by 7%. To import buffalo sires' semen of high predicted milk difference at moderate prices till establishment, domestic genetic merit is required.

This article aims to review both the economic impact of reproductive failures on the profitability of water buffalo systems and the effect of different factors on the reproductive performance of water buffaloes. Besides, an overview of various non-hormonal alternatives to improve reproductive performance is made. The optimal reproductive efficiency in water buffaloes implies calving to conception interval around 90 days to reach a calving interval of 400 days, with longer calving intervals having a negative impact on profitability. Reproductive efficiency is the consequence of the interaction of genetic and non-genetic factors, and the recognition of these factors by analyzing the reproductive information must be a priority. Although each factor's impact can be of greater or lesser magnitude depending on the conditions of each herd, some factors like nutrition, milk yield, body condition score, negative energy balance, parity, bull presence, low estrus intensity, and season can be considered high-impact factors. Not all factors are common among farms; therefore each farm must implement a program for the identification, control, and prevention of reproductive problems, especially during early lactation, to prevent a long anestrus; and when artificial insemination is used, so that it is done at the correct time with respect to the beginning of estrus to enhance fertility.

This review's objective is to provide information on the mechanisms that buffaloes express during the thermoregulation process. Generally, the water buffalo is associated with warm and tropical climates. In these systems, the combination of high temperature, relative humidity, and radiation cause different physiological and behavioral changes, particularly during the summer months. Wallowing behavior in water or mud promotes heat dissipation through physical mechanisms, such as conduction, convection, and radiation. Furthermore, the provision of natural or artificial shades contributes to thermoregulation and maintains homeostasis. In production systems in cold climates, the wallowing behavior is inhibited by the water temperature, so it is important to keep the animals protected in stables to avoid the cold winds and rapid drops in temperature, causing increased illness pneumonia and sometimes death. Finally, in cold conditions, the animals require an appropriate diet since the use of energy is distributed mainly for the production of heat. Thus, heat stress and cold stress generates relevant problems in health, welfare, and productivity in water buffaloes. A comprehensive assessment of the severity of the resulting problems associated with thermal stress and specialty in cold stress in water buffaloes is necessary so far, and there's very little information about it in this species.

The river buffalo is an emerging production species worldwide; indeed, it is overtaking other cattle as a producer of meat and milk in some countries. Though both species belong to the Bovidae family, they show significant anatomical, physiological, and behavioral differences due to their different phylogenetic positions. The river buffalo is a rustic animal that can benefit from low-quality, fibrous forages due to its digestive system, in contrast to beef cattle or dairy cows. Besides, the buffalo cow’s reproductive apparatus has fewer cervical muscle rings and a shorter vagina and cervix. This species has maintained its seasonal breeding pattern, also in contrast to Bos indicus and Bos taurus. Even though buffaloes have an inefficient thermoregulating system, scarce hair, and a thicker epidermis, they are more resistant to tropical weather conditions if water for wallowing is available than dairy cows, which in turn adapt better to temperate zones. Due to the morphology of the river buffalo’s mammary glands, they produce less milk, while their conical teats with narrower sphincters decrease predisposition to mastitis compared to dairy cows. Thus, the study of the anatomical and physiological differences among river buffalo, Bos Taurus, and Bos Indicus will allow the implementation of strategies to improve the former’s productivity while also increasing welfare levels according to the production system in which they are raised.

: Considering breeding livestock programs to milk production and type traits based on existence two different ecotypes of Iranian’s buffalo, a study carried out to investigate the population structure of Iranian buffalo and validate its classification accuracy according to different ecotypes from Iran (Azerbaijan and North) using data SNP chip 90K by means Support vector Machine (SVM), Random Forest (RF) and Discriminant Analysis Principal Component (DAPC) methods. A total of 258 buffalo were sampled and genotyped. The results of admixture, multidimensional scaling (MDS), and DAPC showed a close relationship between the animals of different provinces. Two ecotypes indicated higher accuracy of 96% that the Area Under Curve (AUC) confirmed the obtained result of the SVM approach while the DAPC and RF approach demonstrated lower accuracy of 88% and 80 %, respectively. SVM method proved high accuracy compared with DAPC and RF methods and assigned animals to their herds with more accuracy. According to these results, buffaloes distributed in two different ecotypes are one breed, and therefore the same breeding program should be used in the future. The water buffalo ecotype of the northern provinces of Iran and Azerbaijan seem to belong to the same population.

Meat and meat products share an important status among the various food products because of their high biological value with the goodness of nutritional compounds. Meat is a perfect source of protein along with minerals, vitamins, amino acids, essential fatty acids and many other specific nutrients. Socio-economic factors have to lead to a change in lifestyle, which in turn has increased the demand for ready to eat products, among which meat products are also rapidly gaining attraction of consumers. Although these meat products have good nutritional value, they generally contain a large amount of fat and added salts but are lack of dietary fibre which leads to various health problems in human consuming meat and meat products. Lack of dietary fibre in meat products gives birth to coronary heart diseases, diabetes, high blood pressure and intestinal cancer etc. Consumers are growing their consciousness towards the health aspect without compromising on nutritional benefits. Therefore, meat products fortified with significant levels of dietary fibre has been suggested. 28-36 g/day dietary fibre is recommended and which can be met by their incorporation in the diet of people consuming meat and meat products. The insoluble part of dietary fibre helps in regulation of intestinal function whereas soluble dietary fibre regarded as helpful in lowering cholesterol level by absorbing glucose in the intestine. Another critical problem concerning meat and meat products is the lipid oxidation which reduces the shelf life of product during storage. Natural antioxidants are suggested for retarding lipid oxidation and ultimately enhancing the shelf life of the product under storage. Synthetic antioxidants are losing publicity because they have revealed several toxicological effects during various studies. Thus there is a growing trend of use of natural antioxidants along with the dietary fibre obtained from plant sources in meat and meat products. Various food wastes such as fruit and vegetable byproducts from food processing industries can serve the purpose of dietary fibre as well as natural antioxidants because of the polyphenolic compounds present in them. Generally, these by-products from fruit and vegetable processing industries are cheap, and their utilisation develops indirect income generation. The utilisation of vegetable and fruit wastes as a source of dietary fibre and natural antioxidants also reduces pollution to some extent which might be caused by their disposal. Thus along with waste reduction, cost reduction in economic terms, it also helps the environment by decreasing the load of their disposal. The incorporation of these by-products from various plant sources attracts consumers as they improve quality attributes viz. physicochemical, microbiological and organoleptic properties in meat and its products with health benefits and hence gives satisfaction to the consumers regarding their health consciousness.

The present investigation was undertaken on data of Murrah buffaloes from Buffalo Research Centre (BRC), Chaudhary Charan Singh Haryana Agricultural University, Hisar distributed over 20 years (1987 to 2006). The sire effects and ranks of 38 sires were estimated on the basis of their daughters’ performance. The progeny group size of the sires ranged from 3 to 17. The sires were evaluated for the different first lactation production efficiency traits, viz. first lactation milk yield (FLMY), first lactation peak yield (FPY), persistency of first lactation milk yield (P), average yield per day of lactation (MY/FLL), milk yield per day of first calving interval (MCI) and milk yield per day of age at second calving (MSC). Sire's breeding values were estimated by the best linear unbiased procedure (BLUP). The estimated breeding values (EBV) for FLMY, FPY, P, MY/FLL, MCI and MSC ranged from –288.42 to 362.20 kg; -1.44 to 4.36 kg; -14.72 to 21.09; –0.44 to 0.63 kg/day; -0.40 to 0.52 kg and -0.09 to 0.16 kg, respectively. FLMY had high and significant productmoment and rank correlations with all other traits. The highest product-moment and rank correlations were obtained between FLMY and MSC to the tune of 0.863±0.043 and 0.835±0.050, respectively. The results indicated that sire coding 33 was the best and can be used for future breeding purpose.

: The buffalo calf is more challenging to adapt to the transition from breast milk to other substitutes that favor weaning. Growth in the pre-weaning period is affected by the amount of reconstituted milk consumed. When the quantity of reconstituted milk consumed is low, the weaning weight is also low. The gap between the latter and the optimal weight will never be eliminated because the species cannot perform compensatory growth, such as cattle. There is a delay in reaching an optimal live weight to start puberty. The age at first birth is, in fact, lower in those countries that leave all the milk to the calf for meat production or as happens in Italy where there is a suitable milk substitute. In Italy, it has been verified that calves taking almost ad libitum quantities of cow's milk weigh more than 140 kg at 4 months and have their first birth at the age of 22-26 months. As adults, they have an almost zero percentage of vaginal or uterine prolapse. In further experiences on 3672 heifers, it was possible to verify "ex-post" that the calves that had taken a more significant quantity (150 kg vs. 105) of milk substitute had shown age at the first birth in advance of about 6 months (28, 5 versus 34). Future investigations should verify the effect of weaning birth and not just the cost of weaning. Age at first birth is not only an economic parameter, but it is useful for an early evaluation of bulls in progeny tests.

Age at first birth is not only an economic parameter, but it is useful for an early evaluation of bulls in progeny tests.","PeriodicalId":36721,"journal":{"name":"Journal of Buffalo Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45797810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tubal tonsils of 12 adult buffaloes of the local mixed breed were studied using light and electron microscopy. The tonsillar mucosa lined by pseudostratified columnar ciliated epithelium with goblet cells was modified into lymphoepithelial, due to its association with underlying lymphoid tissue. The lymphoepithelial further modified into follicle-associated epithelium (FAE) characterised by absence of the ciliated cells, goblet cells and the presence of more lymphocytes. The FAE exhibited varying modifications and presented M-cells intimately associated with lymphocytes. At places, the change of the epithelium also showed the presence of specialised M-cell like cells without any association with lymphoid tissue. The lymphoid tissue was in the form of isolated lymphocytes, diffuse aggregations and follicles. The goblet cells of the respiratory epithelium and the glandular acinar cells showed positive activity for the different carbohydrate moieties like acidic and neutral mucopolysaccharides, glycogen, mucins, weakly sulfated acidic mucosubstances, hyaluronic acid and sialomucins. Scanning electron microscopy of the mucosal surface presented a dense mat of cilia, and the FAE exhibited a heterogeneous population of microvillus and M-cells. Transmission electronmicroscopy demonstrated the different cell organelles of the various epithelia as well as the cellular profiles of the propria-submucosa, including the high endothelial venules where lymphocytes migration by both inter-endothelial and transvascular routes was also observed. The structural features of the tubal tonsil suggest that new strategies are required to explore this tonsil for targeted delivery of drugs and develop more effective vaccines by the intranasal route.
