ROWTH rate and efficiency of feed utilization are two of the most economically important characters in the production of meat animals. In these days of world shortage of both plant and animal protein, and with an energy crisis looming on the horizon, the necessity both to reduce maintenance costs by speeding up growth rate and to improve the efficiency of growth by improving the efficiency of c...

A sheep digestion trial and two feedlot trials with cattle were conducted to study effects of an ionophore, salinomycin, on nutrient digestibility, ruminal metabolism and cattle performance. In trial 1, addition of salinomycin at 5.5, 11 or 22 ppm to 60% concentrate diets fed to ruminal-cannulated rams had no effect (P greater than .05) on apparent digestibility of dry matter (DM), organic matt...

one experiment was conducted in order to evaluate four levels of macaroni waste including: 0, 10, 20 and 30 percentage in growing turkey feed in a completely randomized design (crd) with 120 local turkey including 3 replicates in 12 pens. during the experiment (3-8 weeks), turkeys received feed and water of free access. weight gain, feed consumption and feed efficiency were measured weekly. dif...

This research project was conducted to evaluate bioavailability and chemical properties of different zinc sources in broiler chickens when fed by practical diets. For that, 312 day-old male Ross 308 broiler chicks were fed from 8-28 day to estimate the biological availability of four zinc sources. Chicks were allocated randomly to 13 experimental diets in a 3 × 4 factorial design. Diets include...

Received April 5, 2016 Revised May 20, 2016 Approved May 27, 2016 Bali Pig is one of germplasm whose existence is very limited until now. This is due to the very low growth and breeding compared to other types such as Landrace pigs, Duroc, and Laghwhite. However, Bali pig has an advantage among others such as able to utilize lack quality feed so it is suitable to maintain in a rural areas. To k...

this investigation aimed to assess genetics of body conformation and feed efficiency traits in a control line of rhode island red (rir) chicken taking single hatched out pedigreed 100 chicks at central avian research institute, izatnagar, india. data was analyzed by least squares analysis of variance. least squares means of chick weight (cw), body weight (bw), shank length (sl), keel length (kl...

Thirty five growing male goats (6.98±0.86 kg BW) were divided into five equal groups with seven animals in each group. The five dietary treatments were consisted of varying proportions of Moringa foliage (Moringa oleifera) and napier grass (Pennisetum purpurium); T1 (100% Moringa foliage); T2 (75% Moringa foliage+25% napier grass); T3 (50% Moringa foliage+50% napier grass); T4 (25% Moringa foli...

ABSTRACT This study aimed to evaluate sweet potato feed as an alternative energy supplement for ovine. A latin-square design was used assess the effects of feeding animals 0, 0.5, 1 and 1.5% their body weight in well ryegrass hay (Lolium multiflorum) twice daily, mineral salt water ad libitum. During this 8 males were housed metabolic cages with urine feces collectors. Each round experimentatio...

ISSN 1652-6880, ISBN 91-576-7081-1 The overall objective of this thesis was to assess the effect of some animal and feed factors on feed intake, behaviour and performance of small ruminants. The experiments were carried out at the Goat and Rabbit Resea...

One hundred eighty 3-wk-old pigs (initial weight 4.8 kg) were utilized in a 35-d growth trial to determine the effects of the carbohydrate and(or) protein fraction of dried whey on pig performance. In addition, 30, 3-wk-old pigs (initial weight 4.9 kg) were used in two digestion trials to study the effects of the whey fraction on nutrient digestibility. Dietary treatments included a corn-soybea...
