The objective of this study was to identify genomic regions and metabolic pathways associated with dry matter intake, average daily gain, feed efficiency and residual feed intake in an experimental Nellore cattle population. The high-density SNP chip (Illumina High-Density Bovine BeadChip, 777k) was used to genotype the animals. The SNP markers effects and their variances were estimated using t...

This experiment was conducted to assess the effect of chicken genotype on the growth performance, feed intake and feed conversion efficiency of the progenies resulting from purebred (Giriraja (Gr) X Giriraja (Gr)), straight (Gr male X Alpha female), reciprocal (Alpha male X Gr female) and Alpha male X White Leghorn (WL) female crosses. Data obtained on body weight, body length, breast girth, ke...

This research aimed to determine the effect of dietary treatments and age on fattening process in cattle. Thirty-six Ongole crossbred cattles were allotted into two different three groups, with six replications for 24 weeks period, 4 preliminary followed by 20 data collection at Beef Cattle Research Station (BCRS). The experimental design was completely randomized a 2 x 3 factorial. cattle plac...

Feed costs account for a large proportion of the costs of pig production representing usually around 50% of the total costs (Aranda and Cleary, 2001). in the Australian pig industry this proportion has been much higher recently due to the shortage of feed resulting from the extensive drought. Selection for feed efficiency is always an important topic, independent of the current drought situatio...

the technical efficiency involved in cocoa production in cross river state was estimated using the stochastic frontier production function analysis. the effects of some selected socio- economic characteristics of the farmers on the efficiency indices were also estimated. the study relied upon primary data generated from interviewing cocoa farmers using a set of structured questionnaire. a multi...

Feed efficiency (FE) is a concept that has gained popularity in recent years in the dairy industry. Monitoring FE is becoming a more common benchmark for monitoring the profitability of milk production relative to dry matter (DM) intake. In today’s markets, feeds and commodities are becoming more costly, which is driving the requirement for more efficient utilization to maintain profitability. ...

Impact of feed efficiency and diet on adaptive variations in the bacterial community in the rumen fluid of cattle Assessment of the microbial ecology of luminal methanogens in cattle with different feed efficiencies Characterization of variation in rumen methanogenic communities under different dietary and host feed efficiency conditions, as determined by PCR-Denaturing Gradient Gel Electrophor...
