Effect of Dietary Niacin and/or Thiamin Supplementations on Growth and Fattening Performance of Buffalo Calves.

Abstract

his study was conducted to evaluate the effect of feeding supplemented diets by ether niacin, thiamin or its mixture on the growth and fattening performance of buffalo calves. A feeding trial was carried out using twenty growing buffalo calves with average initial weight 275±2.6 Kg and aged 14 months. They were divided into four similar groups (5 calves each) in 120-day feeding trial periods using the randomized complete block design. All animals' groups were fed individually along the experimental period on a basal ration (BR) that consisted of 69.5% concentrate feed mixture (CFM), 17.4% rice straw (RS) and 13.1% corn silage (CS) on DM basis. A certain amounts of dietary niacin and/or thiamin were mixed thoroughly with CFM as in the following treatments. Animals were given BR without supplements (T 1 ) as control, BR supplemented with 0.5 g niacin/head/day (T 2 ), BR plus 0.5 g thiamin/h/d (T 3 ) and BR supplemented with 0.25 g niacin and 0.25 g thiamin/h/d (T 4 ). Animals were fed according to allowances of kearl (1982) for buffalo calves. Four digestibility trials were conducted to determine the digestibility and feeding values of the experimental rations. Results indicated that digestibility of DM and OM were insignificantly increased with T 2 and T 3 rations, but significantly (p<0.05) increased with T 4 one, compared with control (T 1 ). Digestibility of CF, EE and NFE followed the same trend of DM among treatments. Otherwise, CP digestibility was slightly improved with all tested rations. The values of TDN, DCP and DE were followed similar trends to that of nutrients digestibility among treatments. Daily feed intake wasn't affected significantly by the two supplements. Total weight gain and daily gain were significantly (p<0.05) higher in all tested rations in comparison of control one, while the highest value had occurred with T 4 . Regarding feed conversion measurement, significant improvement due to both supplements and its mixture were found respecting DM,TDN or DCP: gain, compared with unsupplemented diet (control). Concerning economic evaluation, net revenue and economical efficiency were markedly increased with supplemented rations compared with control one. No significant differences were found among treatments in blood total protein and creatinine. It could be concluded that either niacin or thiamin and its mixture had an effectiveness role for improving the performance of fattening buffalo calves when the concentrate feed mixture was high percentage in their rations.

Performance of Lactating Cows Fed Rations Supplemented with Chromium Methionine, Non-protected Niacin and Yeast

“…The current findings are in line with previous studies on the influence of Cr-Met, niacin, and added to the ruminant rations on the serum TP and their fractions [50,39,54]. Moreover, the niacin and Cr-Met groups had significantly lower serum urea and creatinine levels than the other groups, but there was a significant difference between the niacin and Cr-Met groups.…”

“…Our findings are similar to those by Deka et al [36], who reported that chromium adding to lactating buffaloe rations improved nutrient digestibility, but didn't affected on it with growing cattle [37]. The findings of nutritive values are similar to those obtained by Kraidees et al [38], Abou-Elenin et al [39] and Ghoniem et al [40], when Cr-yeast, niacin, or yeast were added to the ruminant ration.…”

“…In term of economic efficiency, the findings are consistent with those obtained by [7] who added lactating buffalo rations with a blend of Cr-Met, niacin and yeast. Also, Abou-Elenin et al [39], Ghoniem et al [40], and El-Tahan et al [64] observed a similar effect when adding niacin, yeast and organic chromium to the diets of fattening calves, and lactating buffalo, and cows.…”

Nutritional Studies on Compensatory Growth Phenomenon in Fattening Buffalo Calves

“…Chemical composition of ingredients and calculated experimental rations fed to calves during the restricted and re-alimentation periods are presented in Table ( 1). These data revealed that the chemical composition of concentrate feed mixture (CFM), corn silage (CS), berseem hay (BH), ammoniated rice straw (TRS) and calculated composition of experimental rations are within the normal ranges published by Mostafa et al (2015), Abou Elenin et al (2016), Ghoniem, et al (2017) and Abdou (2018). Also, data in Table 1 showed that DM, OM, CP, EE and NFE contents decreased and CF and ash contents increased with decreasing the levels of concentrate mixture in all restricted rations (T2, T3 and T4) than that of control ration (T1, unrestricted ration).…”

Does vitamin blends supplementation affect the animal performance, carcass traits, and nutrient digestibility of young Nellore finishing bulls?

“…For example, according to Bryant et al [ 9 ] and Baldin et al [ 10 ], the supplementation of fat-soluble vitamins alone (A) or associated (D and E) did not influence animal performance and carcass traits of finishing bulls. On the other hand, some studies have demonstrated better productive performance of bulls [ 11 ] and buffaloes [ 12 ] in response to water-soluble vitamin supplementation (vitamins B1 and B3).…”
