“…The initial pH value of beef and buffen (as fresh sample) was 5.82 and 5.56, respectively like as Hamid et al, 2008. The results showed that rapidly declines the pH value just after mixing the curing agents as 3.93 and 3.81 and showing a continuous increase in pH as 5.23 and 4.69 for beef and buffen, respectively which was similar to Xu et al, 2006.…”

The study was conducted to investigate the effect of curing on the quality of beef and buffen and also to find out the relationship between the quality of beef and buffen with their storage time. Six treatments of which three from beef were taken as dry salt cured beef (A 1 ), dry sugar cured beef (A 2 ), brine cured beef (A 3 ) and three from buffen as dry salt cured buffen (A 4 ), dry sugar cured buffen (A 5 ) and brine cured buffen (A 6 ). These samples were cured at room temperature for 10 days and then dried. The dried sample was stored for 120 days and analyzed on first day, 30 th day, 60 th day and 120 th day. The quality of cured meat samples were studied by chemical analysis. All the samples were acceptable up to the end of the storage time. Dry matter, ash, crude protein and ether extract of all the samples decreased gradually with elapse of storage time. The initial (0 day) dry matter, ash, crude protein and ether extract content of the samples were ranged from 98.00-99.10%, 13.07-15.33%, 75.01-81.07% and 3.70-5.50%, respectively and at the end of 120 days of storage the dry matter, ash, crude protein and ether extract content of the samples ranged from 89.50-90.50%, 12.80-14.802%, 73.68-74.97% and 3.35-4.25%, respectively. Statistical analysis indicated that with the elapse of storage time quality parameters of meat samples decreased significantly (P<0.01). Quality parameters also varied among the samples. A significant difference exists in species when considering the value of fat. The relationship between the quality of beef and buffen shows that dry matter and crude protein are highly significant (P<0.01), ether extract is significant (P<0.05) and ash was statistically not significant with their storage times. Although the values are non significant, the loss of protein was lower in brine cured meat than other sample. It may be concluded that, brine curing could be a useful technique for beef and buffen preservation.

“…B eef is widely available source of animal protein in Bangladesh. The annual meat production in Bangladesh is 3.60 million metric ton, where the beef contributes 60.6% of the value (DLS, 2013;Hamid et al, 2008). The feed consumed by cattle can change beef quality through its effect on the quantity of energy of feed available to the animal and through the nutrient composition of the feed (Fluharty et al, 2009).…”

| Twelve Brahman crossbred growing bulls, divided into three groups, were fed three diets; 100% concentrate diet (A), a 1:1 mixed diet on dry matter of Urea-Molasses-Straw (UMS) and concentrate diet (B) and sole UMS diet (C), respectively, to evaluate the effects of concentrate level on slaughterhouse by-products, carcass characteristics and meat traits. The animals were fed for a period of 90 days and three animals from each group were slaughtered at the end of the trial. The results indicated that yield of edible and inedible by-products had no significant difference among diet groups. When expressed in percentage of live weight, hides, shanks, liver and empty stomach were greater (P<0.05) in animals fed diet C compared to those in diet A and B, whereas no difference was found for those between the last two diets. There was no variation between diet A and B in carcass weight, while it was significantly (P<0.01) lower in diet C. Among carcass traits, hotdressing percentage, kidney-pelvic-heart fat, abdominal fat and back fat thickness increased linearly (P<0.01) with the increased level of concentrate in diets, while Longissimus muscle area did not vary among diet groups. Dietary treatments had no influence (P>0.05) on the content of moisture and protein in meat, but concentrate supplementation reduced ash content and increased the amount of fat (P<0.01) compared to UMS group. Therefore, considering carcass and meat traits, a mixed diet of concentrate and UMS may be fed to Brahman crossbred bulls for fattening.* The ME value of each ingredient was estimated using the equation; ME (MJ/kg DM) = 13.50 + 0.263 EE% -0.133 ash % -0.136 ADF% (MAFF, 1984); The ME value of concentrate mixture (100%) was calculated using the estimated ME value of all ingredients; ME value of UMS (100%) was calculated assuming 6.2 MJ ME /kg DM of straw (Khan, 2008) and 13.0 MJ ME /kg DM of molasses (Dugmore, 1995); ME for diet B= Average of diet A and C= 9.65 MJ ME /kg DM of diet

Background: Small ruminant animals (SRA) have been associated with humans since their domestication are of world significance as socioeconomic animals providing products (meat, milk, wool, hair) that are in growing demand and sustainability of rural economics and many ecosystems with poverty elevation and food security in rural people in developing world including Bangladesh. People clearly want the benefit of SRA with the application of knowledge of science and technological research. Some research progress on production and management of SRA has been made during the past five decades in Bangladesh. However, such research information is often fragmented and not easily accessible, although these research findings are essential for further research and effective SRA development planning. Objective: This review aimed to improve the information based on various aspects of production and management of SRA by compiling and reviewing published research findings to identify constraints of their production for practical and sustainable solutions. Materials and Methods: A systematic literature of review of research articles on production and management of SRA published mainly in journals from 1968 to early 2021 of Bangladesh has been reviewed. A total of 332 inland research articles on these aspects supported with 19 foreign related articles have been reviewed and analyzed. Results: Bangladesh has approximately 26.435 million goats and 3.607 million sheep. Among goat population, 90% Black Bengal goat (BBG), 8.0% Jamunapari (JP) and 2.0% crossbred goats. Ten phenotypic coat color characteristics of BBG with high performance with solid black color goats documented. Sheep and goats are considered polyestrous species, and the average gestation length lasts for 150 days and give birth twice a year under good management and nutrition. Most of the smallholder farmers (80.5-95%) are raised their goats in semi-intensive system and 47% rural women are involved in goat rearing. Approximately 96% goat farmers and 60% sheep farmers used roadside grass and tree leaves and only 4.0% goat farmers used cultivated fodder whereas 40% sheep farmers used cultivated and road side grass to feed their sheep. Daily supplement of 100-300g concentrate to grazing SRA improved the growth and carcass gain, productive and reproductive performances. Castrated goats at eight weeks of age showed a much higher growth rate (76.33g/day) than un-castrated (62.72g/day) goats. The productive and reproductive performances of SRA have been reviewed and discussed. The BBG has excellent reproductive efficiency but its lower live weight and milk yield encouraged for crossbreeding with exotic bucks. The meat and milk yield traits of crossbred improved but reproductive efficiency decreased in comparison to BBG. Selection breeding of BBG not only increased live weight but also improved carcass value and preserves the indigenous genetic resources from extinction of unplanned breeding. Similarly, the crossbreds between native ewes  exotic rams resulted positive effect on wool quality and live weight but a negative effect on prolificacy and lambing interval. Almost all SRA farmers depended on natural breeding system with some research data on the uses of AI and more than 70% farmers are being faced breeding service shortages. Major advances in methods of semen collection and evaluation, evaluation of male fertility, cryopreservation of sperm and estrous cycle control have been reported in both the goat and sheep in Bangladesh. In addition, knowledge of ovulation control, timing of insemination, gamete biology has also been reported in inland literature. The average slaughtering age of BBG reported to be approximately 12 months whereas in native Bengal sheep has been suggested to be 6 to 9 with an average of 8 months to get maximum return. The major challenges for SRA production are breeds, poor management, inadequate feeds, breeding bucks and rams and high neonatal mortality (kids 25.2%) and lambs (12.4%) in Bangladesh. Conclusions: The SRA rearing as smallholder farmers managed mostly semi-intensive system and requires improved feeding, provision of veterinary medical services, financial assistance, improve natural breeding and/or AI services and extension services to encourage and enhance production of sheep and goat at rural levels in Bangladesh. An improvement in the performance of SRA would directly improve the diet and standard of living of rural smallholder farmers in Bangladesh.
