The present work aimed at studying growth pattern and carcass traits in pearl grey guinea fowl fed on dietary Neem (Azadirachta indica) leaf powder (NLP) over a period of 12 weeks. Day old guinea fowl keets (n=120) were randomly assigned to four treatment groups, each with 3 replicates. The first treatment was designated as control (T0) in which no supplement was added to the feed, while in tre...

One of the central tenets of ecological stoichiometry is that consumer growth rate is strongly determined by food phosphorus (P) content. In planktonic organisms population growth rates of zooplankton have repeatedly been shown to be reduced when fed with P-limited algal food sources. However, P-limitation may also affect other quality-related aspects of algae, such as biochemical composition o...

The present investigation aimed to conduct a genetic study of dairy cattle and buffalo bulls based on economic traits and their phenotypic correlation. The means of various economic traits in both the species are presented. Cattle bulls reported a better libido score, Flehmen response, requirement of mounting stimulus and semen volume, conception rate and expected predicted difference for milk ...

the genetic polymorphism of insulin-like growth factor binding protein ( igfbp-3 ) and its association with the growth traits namely condition factor, body weight, and total length were investigated in common carp cyprinus carpio using pcr- single strand conformation polymorphism (sscp) technique. caudal fin clips from 120 c. carpio , aging 5 months, were used in this study and a 330 bp dna fra...

the data were collected from 1992 to 2009 in burri, white boni and black boni sheep maintained at the regional research station in the central highlands of yemen. data were analyzed to study the effects of environmental and genetic factors on body weight and growth rate from birth to weaning. the least square means for body weights (bw) were 2.54, 2.18 and 2.26 kg for birth; 12.49, 10.58 and 11...

The National Longitudinal Study of Adolescent Health data were used to test predictions from life history theory. We hypothesized that (1) in young adulthood an emerging life history strategy would exist as a common factor underlying many life history traits (e.g., health, relationship stability, economic success), (2) both environmental harshness and unpredictability would account for unique v...

The data on 6772 growth records of Sirohi goats maintained at All India Coordinated Research Projecton Sirohi goat at Livestock Research Station, Vallabhnagar, Udaipur, India, and recorded between 2004 and 2016, were analysed to study the growth related traits and their genetic control. The overall least squares means of body weight at birth, W3M, W6M, W9M, W12M, were 2.34 ± 0.03, 12.44 ± 0.19,...

Rhacophoridae, a family of morphologically cryptic frogs, with many genetically distinct evolutionary lineages, is understudied with respect to skeletal morphology, life history traits and skeletal ontogeny. Here we analyze two species each from two sister lineages, Taruga and Polypedates, and compare their postembryonic skeletal ontogeny, larval chondrocrania and adult osteology in the context...

Empirical studies have shown that belowground feeding herbivores can affect the performance of aboveground herbivores in different ways. Often the critical life-history parameters underlying the observed performance effects remain unexplored. In order to better understand the cause for the observed effects on aboveground herbivores, these ecological mechanisms must be better understood. In this...
