Guinea Fowl Case Study
This study was carried out to estimate and evaluate the growth performance and carcass yield of the black and pearl guinea fowl and their crosses. The following three mating groups were established: Pearl male X Pearl female (PXP), Black male X Black female (BXB) and Black male X Pearl female (BXP), from which a total of 317 guinea fowl keets were obtained in six hatches and used for the study. There were 100 PXP, 118 BXB and 99 BXP keets. Growth parameters estimated were body weight, body weight gain, feed intake and feed conversion ratio. Carcass traits studied include live weight at point of slaughter, slaughter weight, dressed weight and dressing percentage. Carcass traits were taken at 14 weeks of age. All the growth performance traits …show more content…
Means with significant difference were separated using Duncan’s Multiple Range Test (Duncan, 1955). RESULTS Growth performance of the three genotypes of guinea fowl: Results of the growth performance of the three genotypes of guinea fowl are presented in Table1. All the growth performance traits studied did not differ significantly (P > 0.05) across the genotype groups, except body weight at 10, 12 and 14 weeks of age. Birds of the PXP genotype exhibited the highest numerical body weight from 2- 14 weeks of age, though they had the least day old body weight (24.88g). They were however significantly different (P < 0.05) at 10-14 weeks old from the other two genotype groups. The PXP genotype similarly manifested a higher body weight gain from Table 1: Mean growth performance of three genotypes of guinea fowl Weeks Parameter Genotypes SEM P × P B × B B×P Wk2 Body weight (g) 100.79 97.62 99.91 2.40 Body weight gain (g/bird) 75.96 71.92 73.22 2.35 2-weekly feed intake (g/bird) 203.17 203.17 203.17 …show more content…
Saina (2005), on the other hand, reported average daily weight gain of 8g in guinea fowls kept under intensive system of management, which is similar to the results of the present study. The author however, obtained higher average daily weight gain of 12.3g for guinea fowls raised under the semi-extensive system of management. Nobo et al. (2012) reported average daily weight gain of 12.8-13.8g in guinea fowls raised under intensive system of

Caged Birds Chapter Summary
813 Words | 4 PagesOne of this week’s readings focused on Ch. 5, “Caged Birds,” in Professor Lytle Hernandez’s book City of Inmates: Conquest, Rebellion, and the Rise of Human Caging in Los Angeles, 1771-1965, and this chapter was particularly interesting because it further explained the development of immigration control in the United States. As a continuation from the last chapter, there was a huge emphasis in the Chinese Exclusion Act of 1882 and the Geary Act of 1892. This essentially prohibited Chinese laborers from immigrating to the United States, as well as eventually requiring these people to comply with regulations. “Caged Birds” encapsulates the events afterwards, as the book heads well into the early-1900’s. The disenfranchisement of immigrants develops towards further exclusivity because “[by] 1917, Congress had banned all Asian immigration to the Unites States and also categorically prohibited all prostitutes, convicts, anarchists, epileptics, ‘lunatics,’ ‘

Spring Predator Case Study
547 Words | 3 PagesBy the end of the millennial the population had doubled in size. Conservation groups such as Delta Waterfowl and the 1985 Conservation Reserve Program have made efforts in predatory control and by introducing more wetlands within a given area. In some cases waterfowl nest success was as low as 11%, far below the minimum number to maintain the current population. Conservation efforts have seen triumphal outcomes nearly doubling nest success seeing numbers as high as 22.9%. With constant implications of spring predator management and with new habitat being established, waterfowl numbers can continue to see an increase.
Chickadee Foraging Habits Lab Report
1068 Words | 5 PagesJoshua Rabideau 11/10/2016 BIOL 380 – Lab: Monday Black-Capped Chickadee Foraging Habits There are numerous organisms and interactions occurring within any ecosystem. Many times, the interactions between organisms and habitats are based on the energy needs of the organisms. In this experiment, a null hypothesis that the Black-capped Chickadee forages on various trees at random. Upon data analysis of the gathered information, it can be determined that the Black-capped chickadee were not choosing foraging sites at random. The results of a chi square test gave a value of 19,890 which is significantly larger than the 16.812 value needed to void the null hypothesis with six degrees of freedom; the probability that this variation was due to chance is less than .01.
Tweezer Beaked Bird
680 Words | 3 PagesWhen looking at results from the mountain area it is clearly evident that the spoon beaked bird was the most adapted to collecting the beans available in relation to the four bird species. The spoon beaked bird had a product difference of 58.75 between its closest competitors the fork billed bird with an average collection of 14.25 followed by the tweezer beaked bird with an average of 6.75 and finally the chopstick billed bird with a collection average of 1.25. Looking at these results it can be identified that smaller beaks with wider surface area prove more efficient in the process of collecting larger round objects such as the beans due to their ability to carry out scooping motions more efficiently. It can be assumed that within the next

Turkeys And Chicken Research Paper
240 Words | 1 PagesTurkeys and Chickens are the two most abused animals in the world. Birds who survive the horrific conditions of broiler sheds or battery cages are transported to the slaughterhouse. Workers rush around grabbing multiple birds by their legs, carelessly flung into cages, a process which breaks many bones and can even snap necks. The journey may be hundreds of miles, but they are given no food or water through any of the process, no matter the conditions. When the animals meet the destination they are poured from crates and grabbed from their legs, put in shackles hanging upside down, the workers break their legs in the process.
Comparing Two Captive Birds
1342 Words | 6 PagesBecause flamingos can use different feeding methods and can filter selectively, and because some food items (algae, slime) are processed faster than others (seeds, mollusks), in most cases, the relative proportions of items consumed are not known. Flamingos of the same species, in nearby bodies of water, can be consuming very different diets (Jenkin, 1957; Hurlbert, 1982; Hurlbert et al., 1986; Vareschi, 1978;Arengo and Baldessari, 1999; Baldassare and Arengo, 2000). Feeding by large flamingo flocks has significant impact on the relative abundance of available food items in a given body of water (Tuite, 2000; Hurlburt et al., 1986). However, because in some areas flamingos feed on ‘monocultures’, we know that diets for individuals of some species can vary from 100% herbivorous (Spirulina) to 100% carnivorous
