A total of 343 calves (males and females) were evaluated for preweaning average daily gain, weaning weight (WW), feedlot average daily gain to slaughter (ADGF), slaughter weight (SW), pelvic height (PH), pelvic width, pelvic area, weaning conformation score (WS) and ratio of weaning weight to the dam's weight at weaning (R). Mating types included straight-bred Angus (A) and Santa Gertrudis (S),...

this study highlights the costs and benefits of indigenous beef cattle fattening schemes in shinyanga urban and kishapu districts in tanzania. specifically, in this study the net profit (np) for fatteners between beef cattle fattening schemes has been determined. the schemes were divided into two main categories, scheme 1 in which the animals were fed on cottonseed hulls (cshl) based diets and ...

this experiment was conducted to determine the effect of feeding alfalfa hay and starter fiber level on feed intake and performance of holstein dairy calves, using thirty two male calves in a completely randomized design assigned to four diets in a 2×2 factorial arrangement. the experimental treatments were as follow: t1: starter with low fiber and without alfalfa hay, t2: starter with low fibe...

Pedigree records of 17250 Thalli sheep with 17030 lambings maintained at the Livestock Experiment Station, Rakh Ghulaman, Distt. Bhakkar, Pakistan during the period from 1975 to 2004 were utilized in the present study. Average values for birth weight, weights at 60 and 90 days of age, weaning weight and preweaning average daily gain were 4.11 ± 0.82, 11.58 ± 3.57, 14.92 ± 4.56, 18.95 ± 4.56 and...

OBJECTIVE Two experiments were conducted to evaluate the effects on growth performance, digestibility, and blood metabolites of lambs during pre- and post-weaning period of inclusion of a commercial probiotic (PRO) containing a mixture of two strains of Pediococcus, Pediococcus acidilactici (1×106 colony-forming unit [cfu]/g) and Pediococcus pentosaceus (1.3×106 cfu/g), with dextrose as the car...

Embryo cryopreservation is a valuable tool for maintaining genetic variability and preserving breeds lines, allowing to assess the response selection enabling diffusion. This study aimed evaluate impact of rederivation by embryo vitrification transfer procedures on growth reproductive traits in paternal rabbit line selected average daily gain from weaning (28 days old) fattening (63 old). The r...

The aim of this study was to evaluate the effect sex on fattening performance and carcass characteristics Kivircik lambs. Fifty head weaned lambs, half males females, were used in period. After weaning, growth feed consumption male female lambs fattened for 56 days recorded. Average daily weight gain differed significantly (P

The objective of the present study was to evaluate the effects of inbreeding on average daily gains and Kleiber ratios in Moghani sheep. Traits included average daily gain from birth to 3 months (ADG1), average daily gain from birth to 6 months (ADG2), average daily gain from 3 months to 6 months (ADG3), average daily gain from 3 months to 9 months (ADG4), average daily gain from 3 months to ye...

The importance of birth-to-weaning average daily gain as a determinant of weight at a final age and yield of marketable pork was investigated. Treatments were imposed to create variation in birthto-weaning ADG independent of birth weight. Newborn pigs were cross-fostered to create litters of four through 14 pigs/litter. Creep feed was offered to pigs from 5 d of age or during last 2 d before we...
