The substantial genetic enhancement of broiler chickens, coupled with the use of growth-promoting additives in feed, has led to accelerated growth rates, and elevated fat deposition in broiler. Clove and tulsi, well-known medicinal plants, have been shown to improve both the growth performance and intestinal health of broilers. This study aimed to investigate the impact of clove and tulsi supplementation on the composition and cellular makeup in visceral and subcutaneous fat depots of broiler chickens. Sixty Cobb-500 broiler chicks were randomly divided into four groups to receive different supplemental treatments via drinking water. The groups included: S0 (control), receiving no additional supplements; S1, receiving 0.5% clove and 2% tulsi; S2, receiving 1% clove and 3% tulsi; and S3, receiving 1.5% clove and 4% tulsi from day 8 to 28. On days 14 and 28, five broilers from each group were euthanized, and their visceral and subcutaneous fat depots were collected, weighed, and subjected to histological analysis to assess adipocyte histomorphology and histomorphometry. The S1 and S2 groups exhibited higher relative percentages of visceral fat depot, larger adipocyte size, and a greater percentage of larger adipocytes compared to the control, while adipocyte density was lower. Conversely, the S3 group showed minimal deviation from the control. Notably, no significant histomorphological differences were observed among the experimental groups. These findings suggest that clove and tulsi supplementation may modulate adipose tissue dynamics and cellularity depending on the concentration of supplementation.

ABSTRACT Supplementation of Cv (clove) and Ts (tulsi) augments the growth rate and gut health of broilers. However, studies on their impact on the vital organs and male reproductive system remain scarce. Therefore, the current study aimed to investigate the impact of Cv and Ts supplementation on hematological profiles, as well as the heart, lungs, liver, kidney, and testes of broilers, both morphologically and biometrically. Sixty one-day-old broiler chicks, divided into four homogenous groups (control-T0 and three supplement groups-T1, T2, and T3), were fed 0.5% Cv and 2% Ts (T1), 1% Cv and 3% Ts (T2), and 1.5% Cv and 4% Ts (T3) with drinking water for 21 d. Organ samples were collected on d 14 and d 28 for macroscopic and microscopic (hematoxylin and eosin stain) investigation. Cv and Ts didn’t affect the hematological profile, organ weight gain, and their general histoarchitectures. However, the histomorphometric investigation showed an increased (p

ABSTRACT: In an epoch of the growing risk of antibiotic resistance, there is a dire need to establish an effective novel feeding practice for broiler nutrition as an alternative to antibiotics. Hence, the aim of the current study was to evaluate the impact of clove powder and tulsi extract on the growth performance, gut morphologic and morphometric indices, and cecal microbial status of broiler, as an alternative to antibiotic growth promoters (AGPs). Sixty day-old chicks of Cobb-500 strain were randomly divided into 4 groups, each having 15 birds. Chicks of the control group (T0) were fed commercial broiler feed with no additional supplementation. The treatment groups were offered commercial broiler feed and received clove powder and tulsi extract with drinking water at the rate of 0.5% + 2% (T1), 1% + 3% (T2), and 1.5% + 4% (T3), respectively. Results showed a nonlinear relationship with the dosage of clove and tulsi. All the growth parameters substantially (P < 0.05) improved in T2 while T1 and T3 showed no significant improvement compared to T0. The final body weight was significantly (P < 0.05) higher in T2. Giblet and offal weights showed no noticeable differences except in the intestine and heart where intestine weight markedly (P < 0.05) decreased in T3 and heart weight significantly (P < 0.05) increased in T1 and T2. Clove and tulsi supplementation substantially improved the villus height and villus surface area of the small intestine in T2 while the large intestine remained mostly unaffected by the treatment. Cecal microbial status significantly improved in all the treatment groups having increased (P < 0.05) Lactobacillus spp. count and decreased (P < 0.05) E. coli count compared to T0. Based on the aforementioned findings, it can be concluded that the combination of clove and tulsi can improve the growth performance and gut health of broilers which is largely dose-dependent and might be supplied as a potential alternative to AGPs.

A study was carried out to assess the effect of dietary supplementation of Tulsi (Ocimum sanctum) leaf powder and Fenugreek (Trigonella foenum-graecum L.) seed powder as herbal feed additives on liveability and economics of heat stressed broilers in arid region of Rajasthan. In the study total of 210- day old broiler chicks of Cobb-400 strain were divided into seven treatment groups with three replicates of 10 chicks in each replicate using completely randomized design. The control group (C) was fed on basal diet without any supplementation and other six treatment groups were supplemented with 0.5% Tulsi leaf powder, 1% Tulsi leaf powder, 0.5% Fenugreek seed powder, 1% Fenugreek seed powder, 0.25% Tulsi leaf powder + 0.25% Fenugreek seed powder and 0.5% Tulsi leaf powder + 0.5% Fenugreek seed powder in T1, T2, F1, F2, T1F1 and T2F2 groups, respectively. The findings of basic meteorological parameters revealed that the broiler birds in this experiment were exposed to extreme heat stress. The findings revealed that the supplementation of Tulsi (Ocimum sanctum) leaf powder and Fenugreek (Trigonella foenum-graecum L.) seed powder did not bring any significant reduction in feed cost and total cost for production of 1 kg live weight but numerically it was better in Tulsi and Fenugreek fed birds.

The objective of the study was to evaluate the effect of Occimum sanctum (Tulsi) and Zinziber officinale (Ginger) as feed additives on growth performance of broiler chicks. Two hundred and ten- day-old chicks were purchased from local market and divided into seven treatment groups, with three replicates having 10 chicks each in a completely randomized design for 42 days. Control group was fed on basal diet and T1 & T2 treatment group were supplemented with 0.5 % and 1 % of tulsi leaf powder in the experimental broiler starter and finisher ration, respectively. Likewise, G1 & G2 treatment group were supplemented with 0.5% & 1% of ginger powder in the experimental broiler starter and finisher ration, respectively. T1G1 and T2G2 treatment groups were supplemented with 0.5 % and 1 % of both herbs i.e. tulsi plus ginger powder in combination, respectively. The statistical analysis of data revealed significant (P<0.01) effect of tulsi and ginger supplementation alone and in combination on feed intake and feed conversion ratio. Feed intake, feed conversion ratio was significantly (P<0.01) lower in G1, T2G2 group, respectively and higher for control group. Body weight, body weight gain, daily body weight gain, performance index, protein efficiency ratio was significantly (P<0.01) higher in tulsi and ginger supplemented alone or in combination group as compare to control group and highest for T2G2 group. It could be concluded that supplementation of Occimum sanctum (Tulsi) leaf and Zinziber officinale (Ginger) powder as feed additives alone or in combination at 0.5 % & 1 % of both herbs improved growth performance of broiler chicks.

An experimental trial was conducted to assess the effect of dietary supplementation of Tulsi (Ocimum sanctum) leaf powder and Fenugreek (Trigonella foenum-graecum L.) seed powder as herbal feed additives on performance index, dry matter digestibility and N-balance of heat stressed broilers in arid zone of Rajasthan. A total of 210 one day old broiler chicks of Cobb-400 strain were divided into seven treatment groups with three replicates of 10 chicks in each replicate using completely randomized design. The control group (C) was fed on basal diet without any supplementation and other six treatment groups were supplemented with 0.5% Tulsi leaf powder, 1 % Tulsi leaf powder, 0.5% Fenugreek seed powder, 1 % Fenugreek seed powder, 0.25% Tulsi leaf powder + 0.25% Fenugreek seed powder and 0.5% Tulsi leaf powder + 0.5% Fenugreek seed powder in T1 T2 F1 F2 T1F1 and T2F2 groups, respectively. Statistical analysis of data revealed highly significant (P<0.01 ) effect of Tulsi and Fenugreek' supplementation alone or in combination on overall performance index, dry matter digestibility, nitrogen intake and nitrogen voided. Overall nitrogen balance was significantly (P<0.05) higher in the Tulsi and Fenugreek supplemented groups compared to control group. On the basis of results obtained in the study, it could be concluded that in high ambient temperature in heat stressed broilers, inclusion of Tulsi leaf powder alone at 0.5% level, Fenugreek seed powder alone at 0.5% level and combination of both i.e. Tulsi leaf powder and Fenugreek seed powder at 0.5% level is quite effective for overall well being of the birds.

The role of Clove (Cv) and Tulsi (Ts) supplementation on broiler growth performance and gut health as an alternative to antibiotic growth promoters has already been established. Therefore, the objectives of this study were to investigate the role of Cv and Ts on the serum biochemical profile and meat quality traits in broilers. A total of sixty (60) one-day-old commercial broiler chicks were randomly allotted into four homogenous groups (15 birds per group). They were then fed Cv powder and Ts extract from day (d) 8 to d 28 with drinking water i.e. zero level of Cv or Ts (T0), 0.5% Cv + 2% Ts (T1), 1.0% Cv + 3% Ts (T2), 1.5% Cv + 4% Ts (T3). Blood and meat samples were collected on d 14, 21, and 28 to analyze the serum-biochemical profile and meat quality. Supplementation of Cv and Ts improved serum-biochemical profile by reducing total cholesterol and low-density lipoprotein levels in broilers. However, they did not affect the serum protein levels while the 0.5–1% Cv and 2–3% Ts supplemented groups had higher glucose levels on d 21. Production of breast and thigh meat increased with increased size, and density of myofibers while fed 0.5–1% Cv and 2–3% Ts. On the contrary, 1.5% Cv powder and 4% Ts extract supplementation improved thigh meat color, breast and thigh meat pH as well as the water-holding capacity. The current study findings suggest that Cv and Ts can be used in combination to improve broiler health, production, and meat quality. [ABSTRACT FROM AUTHOR]

The efficacy of tulsi (Ocimum sactum) and neem (Azadirachta indica) leaves extract as a growth promoter were studied in broiler. A total of 40 day-old broiler chicks were purchased from Kazi hatchery and after three days of acclimatization the chicks were randomly divided into four groups (n=10). No vaccination schedule was practiced and no antibiotic was added in ration of group A, B, C, and D respectively. Group A served control without any supplements while group B, C and D were supplemented with combination of tulsi and neem extract @ 1 ml, 2ml and 3 ml/liter of drinking water. Live body weight gain was recorded weekly up to 6th weeks and hematological studies were performed at 21st and 42nd day of experiments. At the end of 42nd day of experiment final body weight of group A, B, C and D were 1561± 12.10 g, 1698± 12.87 g, 1608± 12.04 g and 1763± 13.28 g, respectively. The birds of group D utilized their feed more efficiently among the treatment groups (p<0.05). The net body weight gain were, 1533± 11.98 g, 1443± 11.32 g and 1588± 12.10 g in treated groups compared to control group (1393± 11.07 g ) and total net profit per broiler was 19.08, 40.10, 20.68 and 45.07 Taka , respectively. Hematological parameterss (TEC, PCV, Hb and ESR) were not significantly changed among the treated and control group suggesting no side effects of herbal extracts in broiler. It can be concluded that tulsi and neem extract is economic and safe in broiler production. [ABSTRACT FROM AUTHOR]

An experiment was conducted to study the effect of dietary supplementation of tulsi (Ocimum sanctum) leaf powder on meat cholesterol and serum lipid profile of broiler from day old to 42nd day of age. One hundred fifty day old chicks were distributed into three experimental groups of 50 birds which were further divided into five replicates of 10 birds each. The control (T1 ) group was fed with standard broiler diet and T2 and T3 were fed standard broiler diet plus tulsi leaf powder at the rate of 0.5% and 1% respectively. All the birds were reared under standard managemental conditions. The observations were recorded for cholesterol content of meat and serum lipid profile of broilers. Supplementation of tulsi leaf powder at the rate of 1% for 42 days showed the significant decrease (P<0.01) in breast muscle and thigh muscle cholesterol. Group T2 showed the significant reduction in thigh muscle cholesterol but not in breast muscle cholesterol. The average serum total cholesterol was reduced significantly (P<0.01) in T3 group but not in T2. The average serum HDL cholesterol was increased significantly (P<0.01) in T2 and T3. The average serum triglycerides were significantly reduced in T2 and T3. But higher reduction obtained in birds fed with 1% tulsi leaf powder in diet. The average serum LDL cholesterol was significantly reduced (P<0.01) in T3 followed by T2 group. The study concluded that supplementation of tulsi leaf powder at the rate of 1% in broiler diet for 42 days reduced meat and blood cholesterol levels of broiler. [ABSTRACT FROM AUTHOR]
