RÉSUMÉ
Aim: The purpose of the present study was to evaluate the impact of Ajwain supplementation on the serum biochemical parameters of Pratapdhan chicken breed. Study Design: Descriptive Study. Place and Duration of Study: Department of Livestock Production and Management, Sri Karan Narendra Agriculture University, Jobner, between 12 December 2016 to 5 February 2017. Methodology: A totally randomized strategy was used to disperse 120 Pratapdhan chicks. The chicks were distributed into four treatment groups, each one contained 30 chicks. The treatment groups included the control (basal diet), T1 (basal diet + 0.1% Ajwain seed powder), T2 (basal diet + 0.2% Ajwain seed powder), and T3 (basal diet + 0.3% Ajwain seed powder). Daily records of the shed's temperature and humidity were used to calculate the Temperature Humidity Index (THI). During the experimental period, standard feeding practices and all other management techniques were used. One bird from each replicate was slaughtered on end day of the experiment period (2, 4, 6, and 8 week) to estimate serum biochemical parameters. The experiment lasted 8 weeks. Results: A significant difference (P<0.05) was observed in calcium, phosphorus, and magnesium values, among the biochemical indicators that varied between the treatment groups and the control group at whole tested period except the calcium concentration at 8 weeks of periods was not significantly (P>0.05) difference. Cholesterol value was observed (P<0.05) significantly decreasing with Ajwain supplementation groups when compared to control group. Conclusion: Dietary inclusion of Ajwain seed powder had not negative effect on the serum bio-chemical parameters of Pratapdhan broiler breed and lowering cholesterol concentration, which directly affects humans who consume poultry meat.
RÉSUMÉ
The present investigation was conducted a study on growth performance of weaned kids of Sirohi goat fed with different levels of concentrates for the effect of concentrate feeding on body weight gain. Twenty four kids of Sirohi breed between 3-4 months age were randomly selected on the basis of uniform body weight, age and divided into 3 groups of 8 kids each at the goat farm of S.K.N. College of Agriculture, Jobner. Group T1 served as control supplemented with 50 g concentrate per kid per day for 3 months. Group T2 (treatment) supplemented with 50, 100 and 150 g concentrate and T3 (treatment) with 100, 150 and 200 g concentrate per head per day for 1st, 2nd and 3rd month, respectively. Other management practices were similar for each group. Fodder of khejri loom was offered ad-libitum to all groups. Body weight of kids was recorded weekly. Group T3 fed with more quantity of concentrate achieved the highest (85.77 g/day) average weekly weight gain followed by T2 (69.22 g/day) and control group T1 (61.33 g/day). Maximum average total weight gain per kid was observed in group T3 (7.72 kg) followed by T2 (6.23 kg) and least was found in T1 (5.52 kg). Thus, from above findings it can be concluded that T2 and T3 treatments showed significantly improved growth performance in Sirohi kids and higher level (T3) was relatively the best level in terms of both biological and economical returns
