    Study of nettle grass (Urtica diocia) powder supplementation on growth performance, carcass traits and haemato-biochemical parametes in broiler chicken
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-08) Pandey, Rajesh; Anil Kumar
    This study was conducted to evaluate the effects of dietary nettle (Urtica dioica) plant supplementation on growth performance, carcass characteristics and haematobiochemical parameters in male broiler chicken. A total of 96 broilers (Cobb strain) were randomly allocated in different dietary treatments viz. 1. Control with basal diet (T1), 2. Basal diet with 0.5 percent nettle (T2), 3. Basal diet with 1 percent nettle (T3) and 4. Basal diet with 1.5 percent nettle (T4). There were 3 replications per treatment with 8 chicks in each. The dietary supplementation of the nettle did not influence (P>0.05) any of the growth performance parameter i.e. body weight gain, feed intake and FCR of the broilers during whole experimental period. On day 42, two birds per replicate were slaughtered for determination of carcass and organ weights. In carcass characteristics, percentage breast weight, liver weight and gizzard weight were significantly increased in broilers fed 1 percent, 0.5 percent and 1 percent nettle diet, respectively. Although, feeding diets containing 1 percent nettle significantly affected breast crude protein (P<0.05), nettle at 0.5 percent had no significant influence when compared to control. None of the processing loss related parameters were statistically different among all the treatments. In haematological parameters TEC, PCV, Hb, MCH and MCHC were significantly increased at 1.5 percent nettle and MCV at 0.5 percent nettle supplementation (p<0.05). PCV values had no significant difference among nettle treated groups. Cholesterol and triglyceride of nettle incorporated diet were significantly different (p<0.05) when compared to control. Furthermore, glucose, total protein, albumin, globulin, SGOT and SGPT were numerically improved when compared to control. Results showed that nettle supplementation at 1 percent may be advised to improve the carcass traits and growth performance in broiler chickens and further research to elucidate the mechanism for potentially enhanced growth through nettle supplementation in basal diet of broilers is required.

    Studies on early reproduction traits of female Frieswal progeny under field conditions
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-05) Sunitibala Devi, Laishram; Singh, D.V.
    Present study was carried out from August 7, 2012 to March 31, 2013 in U. S. Nagar district of Uttarakhand on 131 Frieswal heifers reared by 127 farmers under 5 AI centres, and aimed to study farmers’ profile, management practices, morphometric traits, early reproduction traits and performance traits. Maximum of the respondents were educated (73.23 %), owned small herd size of 3AUE (44.09 %), possessed up to 5 acres land (44.09 %) and very few (23.62 %) were landless. Majority of farmers followed good animal husbandry practices for pregnant heifers. Suckling was allowed for milk let down. Male and female calf born ratio was 46.7:53.3 (av. birth weight 26.67±0.74 kg), who received colostrum ad lib, and calf starter and green fodder from 3rd week and dewormers at 4th week of age. Least-squares means (cm) of 47 pubertal and 62 pregnant heifers were 118.7±1.7 and 134.1±1.9 for BL, 114.5±1.3 and 121.3±1.2 for HAW, 143.1±2.3 and 162.7±2.4 for CG, 150.9±3.0 and 173.5±3.0 for PG, 41.0±0.9 and 43.8±0.9 for FL, 29.7±0.9 and 31.7±0.9 for FW, 17.4±0.3 and 19.1±0.4 for EPL, 67.3±1.2 and 70.3±1.1 for HE, 33.6±0.8 and 37.3±1.2 for HK, 109.1±1.2 and 115.0±1.2 for HPB, 112.6±1.4 and 119.6±1.1 for HHB, 3.08±0.07 and 3.83±0.07 m2 for BSA, 5.15±0.23 and 5.62±0.24 mm for SFT and 227.0±9.3 and 331.7±10.9 kg for EBW, respectively. Land holding had significant effect on HAW, HE and HK in pubertal heifers. Whereas, stage of gestation had significant effect on BSA, SFT and EBW in pregnant heifers. Least-squares means for AP, AFAI, ACON, IPC, NAI and LLOC were 485.2±21.8 (n=131), 608.3±27.1 (n=81), 610.2±25.2 (n=77), 36.18±15.62 (n=77), 2.23±0.13 (n=77) and 30.17±3.74 (n=63) days. Significant effects of AIC, YOB, education level, herd size and SOB on AP; of AIC on AFAI; of YOB on AFAI; of AIC on ACON, IPC and LLOC were observed. Discharge and bellowing were the most frequently observed signs of estrus during puberty and conception. AI were mostly performed between 06:00 to 10:00 am. Mean duration of estrus and time of AI after onset of estrus were 21.8±1.4 and 14.69±0.27 hr, respectively. Average GL, AFC, TTC and TEP were 282.1±1.4, 807.0±28.1 days, 3.91±0.76 and 3.23±0.58 hr. Most of the calving occurred between 00:00 to 06:00 am. Average values for WP, WFAI, WS1P, WS2P, WS3P and WFC were 227.0±9.3, 270.64±8.75, 366.6±89.4, 331.1±11.8, 333.7±31.0 and 398.5±3.79 kg, respectively. Most of heifers were born during winter season. In most of the cases puberty, conception and calving occurred during spring season. A few calving were recorded for dystokia (6.76%) who delivered male calf. Milk samples collected from 14 cows on 10th day of fat and SNF percent as 4.1±0.11 and 8.67 ±0.06, respectively.
