    Study on Productive, Reproductive Performance and Milk Composition of Gir Cows under Semi-Arid Conditions
    (2022) Mahur,Giriraj; Datt, Mahesh
    The present study was conducted at Dairy Farm of S.K.N. College of Agriculture, Jobner to assess the productive, reproductive performance and milk composition of Gir cows under semi-arid conditions. The data of 33 Gir cows those had completed three consecutive lactations was collected from the records maintained at college Dairy Farm over a period of Five years (2017 to 2022) for studying productive and reproductive performance. A total of 12 Gir cows which were in early lactation were selected for studying milk composition. This study was conducted from March 2022 to April 2022 with 216 milk samples from Gir cows. This herd is being maintained at S.K.N. College of Agriculture, Jobner Dairy Farm under semi-arid condition. Productive and reproductive performances were analyzed to determine, total lactation milk yield, standard milk yield, lactation length, dry period, service period, gestation period and calving interval during second, third and fourth lactation. The overall means obtained for total lactation milk yield, standard milk yield (305-DMY), lactation length, dry period, service period, gestation period and calving interval in Gir cows were 1833.45±84.91 litres, 2095.81±75.58 litres, 266.04±6.69 days, 128.94±7.16 days, 113.36±7.72 days and 281.53±0.35 days 394.98±7.78 days, respectively

    Impact of Creep Feed and Green fodder on Growth Performance in Pre-weaned Suckling Sirohi Goat Kids
    (2022) Yadav, Gajanand; Juned Akhter
    The present research work entitled “Impact of Creep Feed and Green fodder on Growth Performance in Pre-weaned Suckling Sirohi Goat Kids” was carried out to study the impact of creep feed and moringa green fodder (MGF) on growth performance of kids in terms of body weight gain and morphometric measurements. Twenty four Sirohi goat kids of one month of age were randomly selected and divided into four treatment groups of each having six kids at the Goat Unit of S.K.N. College of Agriculture, Jobner. Treatment T1 served as control), treatment T2 supplemented with 1.0 per cent of body weight of creep feed, Treatment T3 supplemented with 1.0 per cent of body weight of creep feed with MGF ad-lib and treatment T4 supplemented with 1.5 per cent of body weight of creep feed with MGF ad-lib feed for one month to four months of age and Groundnut straw fed ad-lib to all kids during whole experimental period. All kids were allowed to suckle their mother milk during morning and evening. Other management practices were similar for each treatment. Body weight of kids and other morphometric parameters viz., body length, wither height, paunch girth, heart girth and loin width of kids was observed fortnightly. Treatment T4 fed higher level of creepfeed with MGF achieved the highest (111.48 g/day) average daily weight gain followed by T3 (104.63 g/day), T2 (92.41 g/day) and control treatment T1 (53.70 g/ day). Highest average total weight gain per kid was recorded in treatment T4 (10.03 kg) followed by T3 (9.42 kg), T2 (8.31kg) and least found in control treatment T1 (4.83 kg). The overall increase in body length, wither height, paunch girth, heart girth and loin width was highest in T4, followed by T3, T2 and control treatment T1. The difference between treatments for average body weight gain, daily weight gain, body length, wither height, paunch girth, heart girth and loin width was significant. The correlation coefficient of body weight with morphometric measurements was highly positive. It is concluded from the results that there was significant increase in fortnightly weight gain and other morphometric measurements of kids supplemented with higher level of creep feed with MGF in diet.

    Effect of Different Levels of Ashwagandha (Withania somnifera) Root Powder on Performance of Kuroiler Chicks
    (2022) JOGI, JAGPAL; Mahesh Datt
    The present study was conducted to observe the effect of different levels of Ashwagandha (Withania somnifera) root powder on the performance of Kuroiler chicks. One hundred twenty unsexed Kuroiler chicks (day old) were used on a completely randomized design in 4 treatments with 3 replicates, each consisting of 10 chicks. The treatments included the control group (T1) fed with chick starter feed and other groups were kept on basal diet mixed with Ashwagandha root powder @ 0.5%, 1.0% and 1.5% in T2, T3 and T4, respectively. All other management practices were followed as per recommendation during the experimental period of 56 days. The feed intake and body weight of chicks was recorded at weekly intervals for further analysis. The average body weight, body weight gain, feed intake, feed conversion ratio, performance index, protein efficiency and energy efficiency ratio were significantly higher in T3 group (ARP @ 1.0%) than all other treatments. The feeding of Ashwagandha as a feed additive has not shown any significant effect on mortality rate of Kuroiler chicks. The mortality during the experimental period of 56 days was 5.83%. The highest Benefit cost ratio (1.81) was observed in T3 group followed by T2 (1.78), T1 (1.71) and T4 (1.58). Thus, it can be concluded that, the supplementation of Ashwagandha at 1.0% level was found beneficial in improving body weight, weight gain, feed conversion, protein efficiency and energy efficiency ratio. It can also be concluded that Ashwagandha can be used as efficient, effective and economical alternative to chemical growth promoters in poultry industry. * A post graduate agriculture student, Department of Livestock Producti
