There are several methods of feed restriction but some of them are inconsistent with broilers welfare terms, and some other methods are inapplicable in the production field. Also, duration of feed restriction is one of several factors which affected on the response of broilers. This study aimed to evaluate different feed restriction methods(low protein diet, maintenance diet or low sodium diet). Duration of feed restriction (3, 6 or 9 d.) and sex of birds were also studied. The results showed that applying feed restriction using LPD for 3 days improved the overall performance of males. While using MD or applying feed restriction for 6 days was more severe. Using low sodium diet for 3 days improved performance of males while increasing the period of restriction to 6 or 9 days reduced the final body weight. The females fed low sodium diet did not compensate their body weight as the control. Applying feed restriction for 6 or 9 days improved the overall feed conversion ratio of female chicks. ····· 10361739

In Nigeria however, the estimate is that women produce about 80% of food production. There has been an increase in female-headed households along with female-headed farms due to a variety of factors. Wives are left with the responsibility of farm management, family care and household maintenance. Women`s performance in agriculture is however poor as a result of unequal privileges and opportunities availed them in contrast to their male counterparts. Theses privileges and opportunities are in the areas of credit facilities, access to land, access to education, labour saving technology and extension services. Others are neglect and absence of support from their spouses and families. Data generated from questionnaires were analyzed using frequency, percentage and regression analysis. It was discovered that age of respondents, farming experience, costs of fertilizer and herbicide were statistically significant at 1% level with respect to the farmers` output values. Access to credit and labour were major problems limiting the agricultural productivity of 77.5% and 70% of the farmers respectively. ····· 10361717

The involvement of body fat or plasma leptin in long-term feed intake regulation has become clearer, showing 25% reduction from 16 23 months (fattening period) of adlibitum feeding in fattening steers. Likewise, the insulin induced short term reduction in feed intake (24%) suggests the involvement of plasma leptin. The association of breed (Purebred Hereford vs Backcrossed Hereford) and feeding system shows significant elevation of plasma leptin of breed with higher growth potential coupled with the sensitivity of plasma leptin to low and high energy level of feeding. At an early period of compensatory growth, plasma IGF-1 shows downregulation of IGF-1 receptors as manifested by lower plasma BUN, indicative of lean deposition. While at latter period of compensatory growth, plasma leptin seems elevated, indicative of increase in body fat deposition. However varying individual responses exists, leading us to investigate the leptin resistance or leptin gene polymorphism in domestic animals. ····· 10361563

The fruit is a good source of digestible sugar (12 to 18%) and appreciable source of protein, fat, fibre and minerals like calcium, phosphorous and iron (Chadha, 2001). Kalipatti is an outstanding variety of sapota cultivated in Gujarat due to its excellent taste and aroma, soft and mellow flesh with less number of seeds, high productivity with little incidence of insect-pest and diseases. Being climacteric in nature, the fruit is highly perishable with limited shelf-life. Due to cold sensitive nature of the fruit, bulk of the produce needs immediate disposal for table purpose and is handled at ambient conditions causing considerable post harvest losses. Hence, value addition through processing is imperative not only for economic utilization of increased production of sapota, but also for checking the commodity losses. This book deals with the research work conducted on standardization of recipe, storage and quality analysis of different innovative value added products of sapota. The book will be of immense value to post graduate students and researchers. ····· 10361546

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Three features of biopesticides that differentiate them from synthetic pesticides and make them attractive to producers are the following:- (i) biopesticides can be used for resistance management, especially since many have multiple modes of action which would reduce the chance of resistance occurring in a particular crop pest (ii) many biopesticides have no or low restricted entry intervals, meaning that post-application, restricted entry into fields is very low (0 4 h) and there are often no limitations prior to harvest and (iii) there are generally exemptions for biopesticides from maximum residue limits because they are considered acceptable and relatively safe. Even though insecticidal formulations based on Bt toxins have been used for many years, it was the development and commercialization of insect-resistant transgenic Bt crops expressing Cry toxins that revolutionized the history of agriculture. Benefits of this technology include high specificity and potency, reduction in chemical pesticide applications, increased crop yield and has the potential to be recommended for pest management in organic farming. ····· 10361495
