Two experiments with nine strains of Single Comb White Leghorn hens were conducted to compare laying house performance of hens given a diet of uniform protein content or a phase-feeding diet in which protein content was reduced from 156 to 148 and then to 140 g/kg at 273 and 414, or 273 and 384 days of age. Performance criteria were egg production, feed and protein intake, egg, quality, egg weight, mortality and body weight. Phase-feeding allowed reductions of 4.2 and 4.3% in protein consumption without reducing egg production, mortality or, except in one strain, body weight. There was an increase of 0.5% in feed consumption, but feed cost was reduced by 1.3%. Phase-feeding increased Haugh units by 0.3% and decreased specific gravity of eggs in one experiment, decreased percent visibly-cracked eggs in the other experiment and had no effect on percent blood spots. Depending on strain, phase-feeding had a variable effect on egg weight in exp. 1 but had no effect in the second experiment. Key words: Phase-feeding, protein utilization, egg production, hen

Quality Measurements

Uniformity in hen and egg traits is an important consideration in commercial layer flocks. There is little information on how individual hen feed consumption and body weight affect egg quality measurements. This study investigated the variation in performance traits of individual hens and associations with egg quality characteristics. Four hundred and fifty-five ISA Brown caged hens in early lay were monitored for 42 days (25 to 30 weeks of age) to collect hen feed consumption and egg production measurements. Forty-four hens from the flock were randomly selected and eggs were collected from the same hen once weekly for albumen, yolk, and shell assessment. The means ± standard deviation of average daily feed intake (ADFI), albumen height, initial body weight (IBW), and final body weight (FBW) were 124 g ± 15, 10.3 mm ± 1.5, 1802 g ± 129, and 2000 g ± 175, respectively. Albumen height was not associated with ADFI (r = 0.18, p = 0.21), IBW (r = −0.04, p = 0.79), or FBW (r = −0.06, p = 0.69). This study showed variation in feed intake, body weight, and albumen quality of individual early-lay hens. Feed intake and body weight did not influence albumen quality.

The objective of the research was to evaluate to effect of feeding mengkudu on performances of broilers. The research design used was completely randomized design. One hundred broilers were distributed into five treatments. The treatments were different levels of mengkudu meal (0, 0.75%, 1.5%, 2.25 % and 3%). The observed measured were feed consumption, average body weight (gain) and feed conversion. Results showed that feeding mengkudu (Morinda Citrifolia L.)  no effect significant (P>0.05) on feed consumption, average body weight and feed conversion.  In conclusion, feeding mengkudu meal up to 3% (in diet) does not negatively affect feed consumption, average body weight, and feed conversion.

Enzyme Supplementation

The present study was conducted to assess the effect of supplementation of Multi-enzymes with lysophospholipids on production performance of pure line White Leghorn layers. Body weights before and after the experiment did not differ significantly across the experimental diets. Irrespective of the dietary treatments, the birds gained 3.83 per cent of live weight relative to its initial body weight. Mean per cent Hen housed egg production was significantly (Pis less than 0.05) higher in diet supplemented with 0.10 MEC-L than other groups. Mean egg weight and average daily feed consumption during 25 to 35 weeks of age indicated no significant effect of enzyme supplementation. Average daily feed consumption per bird in control, 0.05 % and 0.1% multi-enzyme supplemented groups was 108.13, 105.66 and 107.67 g respectively and birds offered control diet recorded numerically more feed intake than enzyme supplemented groups. Comparatively low feed per egg was observed in 0.10 per cent group followed by 0.05 per cent group which offers economic benefits than control diets. However, the egg quality traits between different dietary enzyme supplementation groups showed no significant difference.

ABSTRAK. Ayam Gaok merupakan salah satu rumpun ayam lokal yang memiliki potensi besar dikembangkan. Balai Penelitian Ternak (Balitnak) telah melakukan program seleksi pada ayam Gaok untuk menghasilkan bibit ayam lokal pedaging yang dipanen umur 10 minggu dan dapat dijadikan galur jantan (male line) yang akan disilangkan dengan ayam KUB yang merupakan galur betina (female line). Tujuan dari penelitian ini untuk mengetahui pertumbuhan bobot badan dan karakteristik semen ayam Gaok generasi ke-6 yang dipelihara di Balitnak. Sebanyak 211 ekor anak ayam Gaok umur satu hari dari generasi ke-6 dipelihara pada kandang koloni pada masa starter dan grower. Ayam dewasa dipelihara pada kandang individu. Pakan dan air minum diberikan ad libitum. Bobot badan ayam jantan dan betina pada umur 10 minggu masing-masing 1.075,26 ± 156,55 g (KK= 14,56 %) dan 868,25 ± 109,34 g (KK= 12,59 %). Rerata bobot badan jantan dan betina sudah mulai berbeda nyata (P0,05) pada saat ayam berumur lima minggu. Konsumsi dan konversi pakan sampai umur 10 minggu yakni masing-masing 2.801,61 g dan 2,99. Bobot badan ayam jantan dan betina pada umur 20 minggu masing-masing 2.354,01 ± 280,06 (KK= 11,90%) dan 1.646,5 ± 205,97 g (KK= 12,51%). Volume semen, konsentrasi, motilitas dan persentase sperma hidup ayam Gaok jantan pada umur delapan bulan masing-masing sebesar 0,4 ml, 3.927 × 106, 57,22 dan 62,5%. Bobot badan ayam Gaok umur 10 minggu menunjukkan hasil baik dengan variasi yang cukup seragam. Kuantitas dan kualitas semen ayam Gaok tergolong normal.  (Analysis of body weight and semen characteristic of 6th generation selected gaok chicken) ABSTRACT. Gaok chicken is one of local breed chicken which potentially to be developed. Indonesian Research Institute for Animal Production (IRIAP) have been executed selection program on Gaok chicken to obtain meat type local chicken which is harvested on 10 weeks old age and can be made as male line to be crossed with KUB chicken which is the female line. The objective of this study was to observe growth of body weight and characteristics of semen of Gaok chicken 6th generation which are raised in IRIAP. A number of 211 DOC Gaok chicken 6th generation were raised in colony cage in starter and grower periods. Mature chickens were kept in individual cages. Feed and water were given ad libitum. Body weight male and female at 10 weeks were 1,075.26 ±156.55 g (CV=14,56 %) and 868.25 ± 109.34 g (CV=12,59 %) respectively. Body weight on male and female were started significantly differ from five weeks (P0.05). Feed consumption and conversion for 10 weeks were 2,901.61 g and 2.99, respectively. Body weight male and female at 20 weeks were 2,354.01 ± 280.06 g (CV=11,90 %) and 1,646.5 ± 205.97 g (CV=12,51 %) respectively. Semen volume, concentration, motility and proportion of live sperm of male Gaok chicken were 0.4 ml, 3,927 × 106, 57,22 % and 62.5 %, respectively. 10th week body weight of Gaok chicken showed good results with uniform variation. Quantity and quality of Gaok chicken semen belonged to be normal.

Effect Of Feeding

The objective of the experiment was to evaluate the effect of the feeding of 80 g/kg (R8) and 100 g/kg (R10) of untreated rapeseed (RS) on egg quality including sensory quality in comparison with a control diet without rapeseed (R0). The addition of iodine (I) was also evaluated (1 mg/kg (R10) vs. 3 mg/kg (R10+I)). “Double zero” RS was used. The contents of energy and crude protein were almost the same in the diets. Laying hybrid ISABROWN was used in the experiment. The quality of eggs was analyzed 11 times every 28 days, from 19 to 64 weeks of age. 30 eggs per each group were always analyzed. Boiled eggs were assessed twice around the peak of egg production. Egg weight decreased (<I>P</I> < 0.001) with the increased level of RS (62.9 g, 61.8 g and 60.7 g, respectively). A reduction in egg weight in R8 and R10 diets resulted in the lower weight of albumen and eggshells. The addition of I to R10 diet increased (<I>P</I> < 0.001) egg weight (62.1 g vs. 60.7 g). The yolk proportion in egg weight was the highest (26.0%, <I>P</I> < 0.001) and the albumen weight ratio was the lowest (64.2%, <I>P</I> < 0.001) in group R8. Iodine supplementation improved (<I>P</I> < 0.001) yolk weight (15.7 g vs. 15.3 g). The proportion of RS in the diet did not affect the eggshell strength. An increase in the level of I improved (<I>P</I> < 0.001) eggshell quality (strength 36.1 N vs. 34.0 N and thickness 0.386 mm vs. 0.363 mm). Taste and overall acceptability were lower (<I>P</I> < 0.05) in eggs of hens fed RS. The addition of I did not affect flavour, odour, taste or overall acceptability.
