A study was conducted to evaluate the blood serum, liver, kidney and meat tissues Zn, Cu, Mn and Mg concentrations by collecting samples from two dominant camel (Camels dromedaries) breeds, Majaheem (n = 15 males) and Maghateer (n = 15 males); 1.5±0.5 years old raised under traditional semi intensive system in Saudi Arabia. Blood and tissues samples were prepared and analyzed for the Zn, Cu, Mn and Mg concentrations by Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). Results showed that a significantly (p<0.05) higher Cu and Zn and lower Mn and Mg concentrations in blood serum of the Majaheem compared with the Maghateer breed. Copper and Mg concentration in Majaheem liver were significantly (p<0.01) higher, but lower Zn when compared with the Maghateer breed. For kidney samples, a significantly higher concentrations of Cu (p<0.0001) and lower Mn (p<0.05) and Zn (p<0.05) were found for Majaheem than for Maghateer. Furthermore, a significantly (p<0.05) higher Mg concentration and lower Cu (p<0.05) in meat samples from Majaheem breed when compared with the Maghateer. The inorganic matter percentages of liver, meat and kidney were significantly higher (p<0.05) for the Majaheem breed than for Maghateer (1.91, 1.2 and 1.371 vs. 1.46, 0.76 and 1.07%, respectively). Furthermore, Zn concentration in serum of Majaheem and Maghateer were positively correlated to Zn concentration in meat (R2 = 0.552 and 0.603, respectively; p<0.05). In conclusion, results indicate a breed differences may exist in Cu, Zn, Mn and Mg metabolism as a heritable characteristic. So, further studies are recommended. |

This study was executed to assess the effect of stocking density on carcass processing yield, small intestine morphometric measurements and ileal bacterial count in female Ross 308 from 0-30 day of age. A total of 96 female Ross chicks were randomly distributed in a randomized complete block design among 12 cages with three dietary stocking densities based on final body weight: low (28.0 kg m-2), medium (37.0 kg m-2) and high (40.0 kg m-2) which was equivalent to 0.050, 0.037 and 0.030 m2/bird, respectively. Results revealed that heavier breasts were obtained from birds which had subjected to the low stocking density (p<0.001). Total small intestine lengths and weights from birds which were subjected to the low density were the longest and the heaviest as compared to the other two groups. Birds in the low and high densities had longer villi in the duodenum and jejunum than did the group in the medium density. Ileal Clostridium perfringens (C. perfringens) and gram negative Bacilli counts in the low density birds tended to be the lowest among all groups (p<0.05). Based on presented evidences it can be concluded that increasing the stocking density of chicks from 28 to 40 kg of BW m-2 resulted in poor performance and could jeopardize their welfare. |

Recently, animal food industry has shown an increasing interest in Direct-Fed Microbials (DFM) to keep the concept of safe food supply
at the consumer level. In the absence of suitable growth stimulant after banning the use of antibiotics in animal feed, a positive
manipulation of rumen microbes has become the field research for entrepreneurs and research scientists. Direct-fed microbials is a term
reserved for naturally occurring live microbes that can be supplemented orally to produce a beneficial health response in the host animal.
A number of genera of live microorganisms including; bacteria, yeast and fungi are frequently used in different combination feed as DFM
for domestic ruminants. It has been documented that these live culture of microbes improve ruminant productivity, milk production,
immunity, digestibility of feed, counter infectious pathogens and protect health. Possible attempts have also been undertaken to justify
the mechanism of these microbes. This review tries to summarize the effect of supplementation of DFM on the production, immune
response, fermentation pattern and safeguarding health. The discussed concepts and advances concerning to DFM implementation will
be useful not only for the researchers, animal owners, feed manufacturers, pharmacists, pharmaceutical companies, stake holders but
will also boost the economic gains and profits by promoting the ruminant health and production through feed modification. |

Eighteen Awassi lambs (4 month old; mean BW 23.8±1.3 kg) were used in a 60 days trial to investigate the effects of naringin supplementation on performance and physiological responses of heat stressed lambs. The experiment was undertaken during the period of summer months of Saudi Arabia. The lambs were individually housed in a shaded pen and randomly assigned to 1 of 3 treatments: 0 (control), 1 and 2 g of naringin which was weekly administered as an oral dose of naringin (Naringin 98%; Blackburn Distribution, UK). Feed intake was measured weekly and lambs were weighed on days 1, 15, 30, 45 and 60. Blood were collected on days 1, 30 and 60 for measurement of concentrations of metabolic profile. Oral administration with 1 g naringin resulted an increase in ADG (5.2%; p<0.02), a greater gain to feed ratio (17.1%; p<0.05) compared with those in other groups. Lambs receiving orally administered 1 g naringin had a greater (p<0.03) serum concentration of albumin and less (p<0.01) creatinine concentration than non-treated lambs. These results indicate that naringin supplementation has reduces the adverse effects of heat stress and important implications for the sheep industry. |

Twenty lambs were used in this experiment to determine the effect of zinc methionine on productive
performance of growing Awassi lambs. The lambs were divided to five groups, the dietary treatments were
the control diet (C), the control diet plus zinc oxide (ZnO), the control diet plus (0.1 g h-1 d-1 (Z1)), (0.2
g h-1 d-1 (Z2)), (0.3 g h-1 d-1 (Z3)) zinc methionine. Although there is no significant differences between
the groups in the daily gain and feed conversion but the growth rate of Z1 and Z3 were higher than C and
values of feed conversion of ZnO, Z2 and Z3 were higher than C. The growth rate in the last three weeks
for the lambs of Z3 group is higher than the other groups but the differences were not significant. There
are no significant differences (P< 0.05) between C, ZnO and Z3 groups in dressing percentage and carcass
measurements; but the back weight in ZnO group was higher (P< 0.05) than it in the C group. The
concentration of Zn in (spleen, liver, heart, lung and kidney) in the groups of C, ZnO, Z3 was not affected
by treatment but its concentration in meat was significantly (P< 0.05) lower in ZnO group than C group.
The differences between ZnO, Z3 and C groups in the concentration of Cu in (meat, spleen, heart, lung,
kidney) were not significant but the concentration of Cu in the liver of Z3 group lambs was significantly
lower (P< 0.05) than C and ZnO groups. The concentration of Zn and Cu in the blood of all group lambs
did not significantly differ. The results suggest that the dietary Zinc methionine supplementation may
enhance the growth rate of growing Awassi lambs especially in the last period of finishing. Moreover it
appears that Zn from ZnO or Zinc methionine is absorbed to a similar extent, but may be metabolized
differently after absorption. |
