Studies of the macroscopic and microscopic morphology (hippocampus) of brain in Vencobb broiler

Aim: The aim of this study was to study the anatomy of different parts of brain and histology of hippocampus of Vencobb broiler chicken. Materials and Methods: A 12 adult experimental birds were sacrificed by cervical dislocation. After separation of the brain, gross anatomy features were studied. Brain tissue was fixed in 10% buffered neutral formalin for 2-3 days, and then routine dehydration process in ascending grades of ethyl alcohol was done. After xylene cleaning, paraffin impregnation was prepared. Paraffin blocks were cut, and slides were stained by Harris hematoxylin and eosin. Photography was carried out both under lower (×10) and higher (×40) magnifications. Results: The brain structure (dorsal view) of Vencobb bird resembled the outline of a playing card symbol of a “spade.” The brain subdivisions are cerebrum, cerebellum, and medulla oblongata. Cerebrum was devoid of usual convolutions (elevations), gyri, depressions (grooves), and sulci. The cerebral hemispheres were tightly apposed along a median sulcus called interhemispheric fissure and cerebrum and cerebellum were separated by a small transverse fissure. The olfactory bulb was small structures, and the pineal body was clearly visible. The optic lobes were partially hidden under cerebral hemispheres, but laterally, it was large, prominent rounded or spherical bodies of the midbrain. The hippocampal area appeared as dorso-medial protrusion. Different types of neurons were distinguished in the hippocampus were pyramidal neurons, pyramidal-like neurons, and multipolar neurons, etc. There was rich vascularization in the form of blood capillaries throughout the hippocampus. Conclusion: Cerebrum was pear shaped and largest part of the brain. Cerebrum hemisphere was smooth devoid of convolutions, gyri, and depressions, but in the surface of cerebellum, there was the presence of a number of transverse depression (grooves) and sulci subdividing into many folds. Olfactory bulb was poorly developed, whereas optic lobes were rounded and large. The exact boundary line of the hippocampus was not discernable. In hippocampus histology, two categories of neuron local circuit neurons and projection neurons, high vascularization and epididymal lining of lateral ventricle were observed. Hippocampal neurons were comparatively larger without any distinct layers. The afferent neurons projected to the medium septum.

Animal husbandry: Livelihood security of small and marginal farmers in India

poverty alleviation in rural area. It also important for rural economy as supplementing family incomes and generating gainful employment particularly among the landless, labourers, small and marginal farmers and women’s. India supports approximately 18 per cent of the livestock population on 2.5 per cent of its geographical area (Forest survey of India, 2000). The livestock sector contribute national economy in terms of gross domestic product is 4.1 per cent (BAHS, 2014). As many as 75 million women are engaged in the livestock sector as against 15 million men. In India about 72 per cent of the rural population, 57 per cent of the householders keep livestock as important source of income. In rural area of country 73 per cent peoples have their own livestock (Chawla et al., 2002). Indian people get about 20 per cent of their total income from livestock (Vandana, 1996). Over the last two decades, livestock sector has grown at an annual rate of 5.6 per cent, which is higher than the growth of agricultural sector (3.3%). Delgado et al. (1999) reported

Effect of different levels ofAmla powder (Emblica officinalis) on the performance of broilers

Amla powder ( Emblica officinalis ) is an important source of vitamin C. This research was done at Sundaresen School of Animal Husbandry and Dairying, Sam Higginbottom Institute of Agriculture, Technology and Sciences, Allahabad, Uttar Pradesh. The aim of this study was to determine weekly body weight and weekly feed intake supplemented with vitamin C powder in following different levels. A total of 45 day old chicks (DOC) of same hatch were distributed into five groups i.e. T 0 (Control), treatments T 1 , T 2 , T 3 and T 4 with three sub groups comprising of three birds. T 0 (control) were fed with standard ration recommended by NRC. The birds of T 1 , T 2 , T 3 and T 4 were supplemented ration with supplemented with 25g, 50g, 75g and 100g Amla powder/kg feed. In conclusion concluded that there was a beneficial effect of Amla powder supplementation in the diet of broilers on body weight and feed intake of broilers. From economic point of view ration supplemented with vit c @ 100g/kg feed was found the best compared to all the treatments.

Role and Importance of Light in Farm Animals and Birds

Photoperiod is the most common environmental factor monitored by animals to alter long-term physiological processes, particularly reproduction and production through its effect on physical activity, hormonal regulation, behaviour etc. Lighting of animal premises is essential elements of animal (Mitev, 2012). Solar radiation directly or indirectly exerts a profound effect on the behavior of animals. In the form of visible radiation (light), the photoperiod governs diurnal and seasonal activity patterns of the animal. Photoperiod is important for the improvement of production efficiency and profitability (Dahl, 2005).

Effect of Level of Jersey Inheritance in Crossbred Cattle on Subsequent Milk Yield

This study was conducted to see the effect of level of Jersey inheritance in cross bred cattle on subsequent milk production. The data subsequent milk production of Jersey (J) and Red Sindhi (RS) cows maintained at dairy farm, Sundersan School of Animal Husbandry and Dairying, Sam Higginbottom Institute of Agriculture, Technology and Sciences Allahabad were recorded form the history sheets of the animals maintained during this period (1930-1962) for the basis of this study. Jersey Sindhi crosses were divided into 4 geneticgroups consisting of 17, 11, 51 and 24 animals in G 1 (1/2J × 1/2RS), G 2 (3/8 J X 5/8 RS), G 3 (1/4 J × 3/4RS), G 4 (1/8J × 7/8 RS). The effects of Jersey inheritance on subsequent milk production were recorded. Dry period has a non-significant effect on subsequent milk yield in all crosses except in 3/8J × 5/8 RS crosses a significant effect was observed on milk yield only. Therefore, due emphasis should be given to the crosses having exotic inheritance 62.5 per cent for selection and cross breeding.

The Effects of Different Treatments of Pre-Milking Manual Tactile Teat Stimulation on Day-to-Day Variation in Milk Yield, Milk Components, Main Milking Phase, Total Milking Time and Average Milk Flow Rate in Crossbred Cattle

The present study was carried out to investigate the effect of different treatments of udder stimulation on day to day variations in milk parameters in cross bred cows. In group T1, milk yield was positively (P<0.01) correlated with main milking phase, total milking time and average milk flow rate. Milking duration was significantly (P<0.01) correlated with total milking time and average milk flow rate. Total milking time was showed positive (P<0.01) correlation with average milk flow rate. Fat percentage had positive (P<0.05) correlation with SNF (r=0.46). Significantly (P<0.05) positive correlation was observed between total solids with lactose and ash content. SNF was significantly (P<0.05) correlated with acidity. Specific gravity was positively (r=0.59) correlated with total solids. In T2, milk yield was significantly (P<0.01) correlated with main milking phase, total milking time, average milk flow rate (r = 0.99) and negatively (P<0.05) correlated with fat percentage. Main milking phase had positive correlation with total milking time and average milk flow rate and negative correlation with fat percentage. Total milking time was significantly correlated with average milk flow rate. Average milk flow rate had negative correlation with fat percentage (r=-0.71). In T3, milk yield was significantly correlated with main milking phase, total milking time and average milk flow rate and negatively with fat percentage (r=-0.55). Total milking time and average milk flow rate were positively correlated with main milking phase and milking duration was negatively correlated with fat percentage (r=-0.54). Total milking time was positively correlated with average milk flow rate and negatively correlated with fat. Fat percentage was negatively correlated with average milk flow rate was with. Ash content and acidity were positively correlated with total solids.

Effect of different colours of light on performance of caged broilers

The objective of this study was to evaluate the performance of the broiler chicken (body weight, feed intake and feed conversion ratio) at the fifth week of age. The broiler chicks were weighed, leg banded and distributed randomly into four groups as treatments, battery type iron cages, feeders, waters and other equipments were thoroughly cleaned disinfected, dried, sterilized by blow torch and finally fumigated by use of mixture of KMnO 4 (potassium permanganates) and formaldehyde before use. The chicks were fed ad libitum with standard starter ration containing CP: 22 per cent and ME:2900 k.cal./kg feed upto 3 weeks age and then after broiler finisher ration with CP: 19 per cent and ME: 3000 k.cal./ kg feed upto 5 weeks age. The broiler chicks of all groups were kept under similar management practices except lighting regimes as per treatment upto five (5) weeks age in battery type iron cages in laboratory. It is concluded colours of light did not show any significant effect on feed intake and feed conversion ratio (FCR) in broilers. The colour of light has a significant effect on the weight gain at the fifth week of age. The milky white and yellow colours of light are effective to obtain higher weekly body weight at five weeks age of caged broilers.

Scientific artificial insemination in swine

Artificial insemination (A.I.) is the process by which semen is deposited in the female reproductive tract during fertile period by means of an instrument to obtain pregnancy. Artificial insemination was first done by Lazarro Spallanzani, physiologist, in the dog (Perry, 1948). The swine industry contributes about 8 per cent of the total meat in India and Uttar Pradesh is first in the swine meat production (BAHS, 2012). Artificial insemination in pigs has been used since the early 1930s but its true development and wide commercial application in the pig industry take place in 1980s. In some European countries, such as Belgium, Italy, Netherlands, Norway and Spain, more than 80 per cent of the females are bred by Artificial insemination and in North America (USA, Canada and Mexico) and Brazil the percentage has already reached 75 per cent in large farm units. In India swine production sector is in his growing stage. The swine industry is well established in the north east part of India. This sector may play an important role for the improving the economic status of the farmers. It requires less input and more benefit due to higher growth rate and high feed conversion efficiency. Scientific techniques of Artificial insemination are essential for economic benefits and sustainable growth for swine industry in the developing Indian condition.
