“…Additionally, the current research found that the feed cost per gain for the pTMR treatment was the lowest because pineapple stem by-product was cheaper than Napier grass and whole corn. Similarly, Maneerat et al (2015) and Boonsaen et al (2017) used pineapple peel silage and cassava chips as an energy source in TMR for feedlot cattle because of its cheaper price. Therefore, by-products form pineapple stems have a high potential to serve as low cost feed for cattle raised in feedlots.…”

“…The frozen sample was weighed before the meat was freeze-dried. The freeze-dried sample was weighed, ground, and the fat content quantified by solvent extraction (petroleum ether, BP 40 -60 °C) using a Soxhlet apparatus (AOAC International, 2005) The production cost was determined using the cattle cost, feed cost and total cost for each beast, which was calculated using equations (1) − (3), according to Boonsaen et al (2017):…”

This experiment was conducted to determine the effects of pineapple stem by-product silage as a feed source in total replacement of Napier or corn silages on growth performance, feed intake and feed efficiency, ruminal fermentation, carcass characteristics and meat quality of Holstein crossbred steers. Forty-eight steers with an average age of 18 months (448.6 ± 51.5 kg) were randomly allocated to three groups (one diet per group) in a completely randomized design. Steers were fed total mixed ration (TMR) containing a roughage-to-concentrate ratio of 20 : 80. The TMR diets contained Napier grass silage (nTMR), whole corn silage (cTMR) or pineapple stem silage (pTMR) and were offered ad libitum for six months. The results revealed that pTMR and cTMR diets resulted in a significantly higher weight gain than nTMR. These results were observed because pTMR and cTMR diets provided more N-free extract (NFE) total digestible nutrients (TDN) than nTMR diet, and the feed conversion efficiencies for pTMR and cTMR diets were higher than those of nTMR. Ruminal pH, ammonia-nitrogen and volatile fatty acid concentrations were not significantly different among dietary treatments. The carcass characteristics of steers fed cTMR and pTMR diets included significantly larger rib eye areas than steers fed nTMR, whereas meat quality was not affected by treatment. Additionally, the current research showed that pTMR diet provided the lowest feed cost per gain. The results suggest that pineapple stem by-product could be regarded as a potential feed source for reducing costs in cattle feedlots.

“…The fatty acid composition of carcass affects not only the economic value of the carcass but also directly affects the health of consumers (15). Increasing awareness of the nutritional functions of PUFA has enhanced the studies on PUFA products, with a focus on eating meat with a high PUFA content and low content of UFA through modern healthy eating habits.…”

The objective of this study was to investigate the effects of intensive fattening with total mixed rations (TMR) on carcass characteristics, meat quality, and chemical composition of the yak meat. Theoretical data has been provided for evaluating the quality of yak meat during natural grazing and short-term fattening. Based on the analysis, we found that in fattening yak, the carcass weight (CWT) was increased by 106.43%, whereas the cooking loss, tenderness, and drop loss were significantly improved due to higher intramuscular fat content and lower moisture (P < 0.05). Protein, fat, calcium, and amino acids were also much higher (P < 0.01) in fattening yak compared with the grazing yak. The levels of albumin (ALB), lactate dehydrogenase (LDH), triglyceride (TRIG), and amylase (AMYL) in serum indicated better nutritional status for fattening yaks. The transcriptomics analysis showed that the high expression of ACSL1 and ACACB genes improved the synthesis and deposition of fat in fattening yak, whereas the regulation of SLC7A8, ATP1A4, ATP1A1, SLC3A2, and CPA3 gene expression weakened the proteolysis. These results indicated that fattening with TMR improves the yield and quality of the yak meat.
