Comparison carcass traits of Azeri buffalo, native and crossbred (native * Holstein) male calves in west Azerbaijan-Iran

Abstract

Iran has 500thousand heads buffalo that 80percent of them distributed in North and North West of Iran and they reared as multi purpose animals providing milk and meat. Farmer believe that buffalo milk had the best quality but because of huge and large head and skin buffaloes carcass isn&rsquo;t suitable that governmental programmer pay a low facilities to buffalo fattener in comparison the cattle fattener thus the objective of this investigation was to the Comparison carcass traits of buffalo, native and Native cows* Holstein (NH) male calves that mostly fattened in this region. Eighty head claves (six heads of each treat) with average 160 kg body weight (BW) were fattened till the 300 kg. Ration and other environmental factors were the same. Three heads of each group&rsquo;s according Iranian Standards slaughtered at abattoir. The slaughter weight, hot carcass weight, and the individual weights of the different slaughter by-products and organs were measured. The carcasses were chilled at 5o C for 24 h. One side of each carcass was cutting into wholesales cuts. Traits included Hot and cold carcass weight, bone, internal fat, meat, cut ability fat, dressing percent, wholesales cuts weight and percent. Wholesales cuts include neck, shoulder, loin, rib and flank and leg weight and percent. The results showed that there were not significant differences between hot and cold carcass weigh, meat, bone and cut ability fat percent. There were significant differences on internal fat, dressing percent and leg (P<0.05). The lowest and highest values for internal fat were observed buffalo and native carcass, respectively. In conclusion because of low internal fat deposition and high valuable wholesales cuts percent may buffalo carcass composition had a better quality in comparison cattle and fattening of buffalo is economically

Effects of age on slaughter performance and meat quality of Binlangjang male buffalo

“…Dressing percentage, meat percentage and carcass meat yield are important indicators for judging the slaughter performance. Dressing percentage decreases with age, ranging from 48.73% to 54.93%, with that of adult bulls six percentage points lower than that of suckling calves, which is consistent with reports by Manafiazar et al, 2007, Rosalina et al, 2007, Rosalina et al, 2008 and Kandeepan et al (2009). Dressing percentage is closely related to variety, age, feeding levels and feeding management.…”

“…In the pH values between biceps femoris and longissimus dorsi (P > 0.05), with pH value in the range of 6.31–6.44, which is in the range in studies by Manafiazar et al, 2007, Rosalina et al, 2007, Rosalina et al, 2008), Kumagai et al (2012), and Awan et al (2014). This may be due to a similar metabolic rate after slaughter between animal breeds.…”

“…At the same age, dressing percentage of Binlangjang buffalo is 3.77% lower than that of buffalo, which is like that of gayals (Qiu et al, 1995, Fan, 2005). The low dressing percentage of buffalo is closely related to its big proportion of non-edible parts (Manafiazar et al, 2007, Rosalina et al, 2007, Rosalina et al, 2008).…”

“…The slaughtered buffalos are basically obsolete cows or 10-year-old bulls without fattening, leading to consumers’ cognitive error in buffalo meat quality and slaughter performance. Studies found that buffalo meat at the appropriate age of slaughter is more tender and fresh than beef, rich in high protein, high essential amino acids, with low intramuscular fat, low saturated fatty acids, low cholesterol and triglycerides, plus ω-6 and ω-3 closely related to human health (Neath et al, 2007, Iqbal et al, 2007, Uriyapongson, 2013, Arganosa, 1973, Ross, 1975, Joksimovic and Oqnjanovic, 1977, Baruah et al, 1990, Anjaneyulu et al, 1990, Anjaneyulu et al, 1994, Bhat and Lakshmanan, 1998, Sharma, 1999, Kondaiah, 2002, Di et al, 2003, Manafiazar et al, 2007, Rosalina et al, 2007, Rosalina et al, 2008, Rao et al, 2009, Choi and Kim, 2009, Kandeepan et al, 2009, Nurainia et al, 2013, Qiu, 1985, Wu et al, 2010, Yang, 2011, Yin et al, 2013, Tao et al, 2014). Kandeepan et al reported that average dressing percentage of buffalo was 55.40–59.00% (Kandeepan et al, 2009) in modern farming mode, with breeding cost lower than that of other buffalo.…”

Effects of Bypass Fat on Buffalo Carcass Characteristics, Meat Nutrient Contents and Profitability

“…Earlier, Lambertz et al [ 10 ] reported a higher carcass fat percentage in buffaloes following supplementation with a 2.0% body weight of concentrate, while Pimpa et al [ 37 ] failed to improve the warm and cold carcass yield of the cattle when fed with 5% fat. Nevertheless, the average carcass yield of the Murrah cross and the swamp buffaloes in this study was markedly lower than the pure-breed Murrah buffaloes, as reported by Biswas and Rajkumar [ 3 ] and Arshadullah et al [ 46 ], likely due to breed differences and the higher proportion of non-edible parts [ 16 , 47 ]. In fact, the Murrah cross in this study recorded a high carcass bone percentage ( p < 0.05).…”
