“…However, published results indicated that FR increased survival rate due to less sudden death, ascites and skeletal disorders (24,25) . Lymphoid organs, antioxidant status and im mune markers FR regimen did not have significant influence on lymphoid organs (Table 2), total antioxidant capacity (TAC), malondialdehyde (MDA), Immunoglobulin M (IgM), Immunoglobulin G (IgG), HIIBD, HIAI, Lysosome activity (LyzA), BacA, PA and PI, but immunoglobulin A (IgA) significantly increased by 3.9 % compared to the control (Table 3).…”

An experiment was conducted to study the response of a slow growing chickens breed "Sinai" to feed restriction (FR) and the effects on growth performance, blood constituents and immune markers using a total number of 60 unsexed 7-d-old chicks. Chickens were housed in battery brooders during d 1 to 35 of age and randomly distributed keeping similar initial body weight, in two FR treatment groups. During 0-6 d of age, chickens were fed ad libitum , a mash commercial diet. During d 7-14 of age, chickens were fed either 100 or 80 % of the daily amount of feed consumed by the control group during the previous day. From d 15 to d 35, chickens were fed ad libitum diets a mash commercial diet. At the end of the experiment, body weight gain on the FR regimen was significantly lower than that of the control group, but feed intake and feed conversion ratio (FCR) were not affected. In addition, red blood cells parameters and white blood cells traits were not negatively affected. However, hemagglutination inhibition titter for New castle disease virus, monocyte and total cholesterol were significantly decreased by FR regimen, but blood plasma albumin and immunoglobulin A significantly increased. In conclusion, slow growing chickens could tolerate 27.2 % FR during the 2 nd week of age without significant differences in feed intake and FCR for the whole period, and general health status and metabolic profiles indicating a compensatory growth during 15-35 d of age although growth was in favour to the unrestricted group.

RESUMENEl comportamiento productivo, constituyentes sanguíneos y marcadores inmunológicos se estudiaron en pollos de la raza SINAI de lento crecimiento bajo un régimen de restricción de alimento (RA). Se utilizaron 60 pollitos de peso similar desde la edad de 1 día hasta los 35 días. Se distribuyeron al azar en dos tratamientos de RA. De 0-6 días de edad, los animales se alimentaron con una mezcla comercial ad libitum . De 7 a 14 días de edad, se alimentaron con la misma dieta ya fuera al 100 o al 80 % de consumo de alimento diario. De 15 a 35 días de edad, todas las réplicas se alimentaron con la misma dieta ad libitum . Después de los 35 días, la ganancia de peso en el régimen RA fue significativamente más baja, a pesar de que la ingesta de alimento y la tasa de conversión alimenticia (TCA) no se vieron afectados. El título de inhibición de la hemaglutinación por el virus de la enfermedad de Newcastle, los monocitos y el colesterol total fueron significativamente más bajos en el tratamiento RA. Los valores de albúmina del plasma sanguíneo y de la inmunoglobulina A fueron más altos en el tratamiento RA. Los pollos de crecimiento lento toleraron una reducción del alimento del 27.2% durante la segunda semana de edad sin exhibir diferencia significativa en la ingesta del alimento y la TCA durante el tiempo de experimentación. A pesar de que el comportamiento productivo fue óptimo para el grupo control, e...

“…Various quantitative and qualitative methods of feed restriction are used in broilers to improve their efficiency of feed utilization and weight gain (Mahmood et al, 2007). Such methods result in temporary reduction of growth rate, while the normal weight of broilers can be attained on removal of feed restriction, thus improving the feed efficiency and decreasing the feeding cost (Mahmood et al, 2007;Sahraei, 2012). The objective of the present study was to evaluate the effect of limiting feeding time by three and six hours during the starter period on broiler chicks` performance.…”

In a completely randomized design, one hundred and twenty one-day old (Arbor acres) broiler chicks were randomly distributed in three treatments, five replicates with eight chicks per a replicate. The treatments were: 24 h ad libitum feeding (A), B feed removal from 9:00 to 12:00 noon (3 fasting hours) and C feed removal from 9:00 to 3:00 pm (6 fasting hours). Feed restriction was applied from 8 to 28 days of age. The experiment lasted from 8 to 37 days of age. The results showed that fasting birds for three and six hours had significantly (p<0.05) no effect on body weight, weight gain, feed intake and feed conversion ratio at 37 days of age.

“…The use of GPA for obtaining the fast growth usually increased the body fats of chicken that lead to high incidence of metabolic disorders, skeletal diseases and mortality [9]. Besides, the feed restriction is one of the main technique to decrease the incidence of metabolic diseases, carcass fat deposition, reduce maintenance requirement and improvement of feed efficiency in broiler chickens production, which enhance the growth and production efficiency [10].…”

The current study was attempted to investigate the effect of Mr. Trivedi's biofield energy treated energized water on chicken. The total 4200 chicks were equally divided into two groups i.e. control and treated. The biofield treated energized water was provided to the treated chicks, while the control chicks were drunk with standard drinking water. During the experiment the parameters such as mortality, body weight, food intake etc. were assessed in both control and energized water treated birds. The mortality rate was reduced in the energized water treated chicks as 54.55% in week 1, 42.11% in week 6, and 39.13% in week 4, as compared to the control chicks. Moreover, the average body weight was increased by 12.50% in week 1 as compared to the control chicks. The feed conversion ratio was gradually decreased which indicated that the energized water treated chicks took less feeds while the body weight was increased in comparison to the control chicks. Besides, the energized water treated birds showed statistically significant (p<0.007) with 15.47% increase in the edible meat weight as compared to the control chicks. Moreover, the feather, skin and internal organ weight were significantly reduced by 21.22% (p<0.001) of energized water treated chicks as compared to the untreated chicks. The protein content was increased by 10.11% and cholesterol was decreased by 4.64% in birds of the treated group as compared to the control. The European efficiency factor was also increased by 10.67% in the energized water treated birds as compared to the control chicks.. The European efficiency factor was also increased by 10.67% in the energized water treated birds as compared to the control chicks. Altogether, the results suggest that Mr. Trivedi's biofield treated energized water could be a cost effective feeding approach in chicken production.
