Fermentation Pattern

A study was planned to ascertain effect of 50 (T1), 60 (T2) and 70 (T3) % lucerne straw in total mixed ration (TMR) on rumen fermentation and blood metabolites in Kankrej crossbred bullocks. Two bullocks were assigned in each treatment using 3 x 3 Latin Square design. The rumen and blood metabolites were evaluated on last day of each period. The pH of strained rumen liquor (SRL) was slightly alkaline (7.09-7.16) on account of green forage feeding in morning before TMR. The pH was lowest at 4 hr post-feeding. The total volatile fatty acids (TVFAs) were 75.79-77.67 mEq/ litre and a reverse trend was observed for TVFAs as compared to pH. The values for ammonia, total, soluble, non-protein and protein nitrogen in SRL were 15.07-17.52, 86.92-90.07, 39.90-46.55, 35.88-40.69 and 46.23-53.50 mg/100 ml, respectively. All nitrogen fractions peaked at 2 hr postfeeding, except protein nitrogen which peaked at 6 hr, showing maximum activity up to 6 hr postfeeding. The values for serum protein, phosphorus and calcium as well as blood haemoglobin were within physiological range. The differences amongst treatments for rumen and blood metabolites were non-significant. The results suggest that lucerne straw can be incorporated up to 70% in TMR of bovines for maintenance without adverse effect on rumen fermentation and blood constituents

AbstractThis study investigated the effects of the percentage of Texel or Rouge de l’Ouest (Rouge) genes in lambs (0, 50, 75 or 100%; the remainder being Greyface (Border Leicester × Scottish Blackface)) on lamb carcass characteristics and meat quality. Ewe lambs were slaughtered at 34, 40, 46 and 52 kg and ram lambs were slaughtered at 40, 46, 52 and 58 kg live weight. Dressing proportion increased (P < 0·001) by 0·53 and 0·27 g carcass weight per kg live weight for each 1% increase in Texel or Rouge genes respectively. Carcass conformation classification increased (P < 0·001) by 0·016 and 0·007 units (on a five-point scale) for each 1% increase in Texel or Rouge genes respectively. Carcass fat depth measures were reduced by Texel and Rouge genes such that at a constant fat depth end point, carcass weight could be increased by 0·029 and 0·023 kg for each 1% increase in Texel or Rouge genes. Carcass lean content increased (P < 0·001) by 0·99 and 0·27 g/kg for each 1% increase in Texel or Rouge genes. Subcutaneous fat content was reduced (P < 0·001) by 0·36 and 0·29 g/kg for each 1% increase in Texel or Rouge genes. Intermuscular fat content was reduced (P < 0·01) by 0·38 g/kg per 1% increase in Texel genes, whereas Rouge genes had no effect. Similarly, bone content was reduced (P < 0·01) by Texel genes only (0·31 g/kg per 1% increase in Texel genes). Warner-Bratzler shear force values showed a quadratic effect with increasing Texel and Rouge genes, with an initial decrease from 0 to 50% followed by an increase to 100%. Cooking loss increased (P = 0·05) as the percentage of Rouge genes in lambs increased. Increasing the percentage of Texel or Rouge genes significantly increased L* values (P < 0·01 and P < 0·05 respectively), b* values (P = 0·05 and P< 0·05 respectively) and H° values (P < 0·001).

Degradable Protein

In a crossover trial, 4 cows were given concentrates containing rapidly and slowly degradable protein in combination with prewilted grass silage. Diets were given in 2 equal daily portions according to DCP and net energy requirements. The trial consisted of 3 main periods of 3 weeks each, with faeces, urine and milk collected and measured during the final week. On 1 day during this week samples of rumen fluid were taken and on 2 days blood samples were taken, directly before the morning feed and 1, 2, 3, 4 and 8 h later. N digestibity and N retention were the same on both rations. A concentrate with slowly-degradable protein resulted in a significantly higher rumen pH and acetate:propionate ratio. Ammonia concn. tended to be lower. Slowly-degradable concentrate protein led to a significantly higher concn. of urea and a lower concn. of insulin in blood. The concn. of several of the essential amino acids, and of the glucogenic amino acids and glycine was significantly lower. There were no significant effects of type of protein on milk yield or milk composition, but there was a tendency for these parameters to increase with ration containing slowly-degradable protein. Results suggest the ration containing slowly-degradable concentrate protein produced a more even rumen fermentation, which promoted a higher acetate:propionate ration in the rumen. On this ration there was a tendency for more gluconeogenesis from amino acids to occur. (Abstract retrieved from CAB Abstracts by CABI’s permission)
