Aim: The aims of this study were to develop and standardize the sausages prepared from meat of spent broiler breeder hens and also to improve the functionality by using ground peanut seed as partial animal fat substitute basing on physico-chemical, proximate and sensory properties of the product. Design of the Study: Conducted six numbers of trails to develop and standardize the functional chicken sausages fortified with ground peanut seed by utilizing cheaply available meat from spent broiler breeder hens. Place and Duration of Study: Work done at Department of Livestock Products Technology, College of Veterinary Science, Tirupati, Chittoor District, Andhra Pradesh India. The duration of study was 2 years (From 2018 to 2019). Methodology: Ground peanut seed used at three different levels as fat replacer in order to study the influence of its addition on physico chemical, proximate, fatty acid composition and sensory evaluation of functional chicken sausages. Results: Results showed that functional chicken sausages fortified with ground peanut seed at 10% level were found to have significantly (P<0.05) higher pH, cooking yield, emulsion stability, hardness, crude protein, crude fiber, total ash, PUFA/SFA ratio, mono and poly unsaturated fatty acids and significantly lower moisture, crude fat, cholesterol and saturated fatty acids when compared to the control and rest of the peanut seed fortified sausages with no significant difference was observed in sensory scores. Conclusion: Replacing chicken fat with ground peanut seeds is possible to develop a healthy fatty acid profile and fiber-enriched chicken sausages.

There is scant information about the reproductive process in broiler breeders, with which to develop a feeding strategy that will be economically optimal for these birds. This study aimed to model the egg production of a flock of broiler breeder hens, using non-isometric equations. The number of eggs produced by 60 broiler breeder hens aged 24–60 weeks was monitored, as was the weight of these eggs and the weights of the components, yolk, albumen and shell. Oviposition sequences and the number and length of pauses between sequences were analysed. Non-isometric functions were applied to predict the weight of the egg; yolk weight was predicted from the age of the hen, while albumen and shell weights were predicted from yolk weight; and egg weight was obtained by summing the component weights. The incidence of soft-shelled and double-yolk eggs was also determined. Yolk weight (YW, g) can be described as YW = 18.03 × (1 – e–0.015 × (t – 103.4)) × e(0.001 × t), where t is the age of the bird (days). The weights of albumen (AW) and shell (SW) were based on YW predictions as follows: AW = 14.38 × YW0.375 and SW = 0.358 × (YW + AW)0.687. The rate of double-yolk egg (DY) production is described by DY = 2.28 × e(0.209 × TFE), and the rate of soft-shelled egg (SS) production by SS = 1.126 + 0.148/(1 – 0.024 × TFE) – 0.056 × TFE, as a function of time from first egg (TFE). On the basis of the results obtained, the model developed here is an accurate reflection of the changes that occur in the number of eggs produced by broiler breeders, as well as in the egg itself and in its components over the entire laying period. This model can thus be used in predicting the nutrient requirements of individual broiler breeder hens, which, when combined with simulated data from a large number of individuals, will accurately describe the laying performance of a flock of broiler breeders.

The immediate effects of a sudden increase in feed allowance on selected morphological and reproductive traits were investigated in broiler breeder hens at 44 wk of age. Fifty Indian River hens were individually caged at 40 wk of age. Prior to 40 wk of age the birds had been feed restricted in accordance with the breeder's recommended feeding program. Five treatment groups (T1, T2, T3, T4 and T5) of 10 birds each were formed based on level of feeding and duration of exposure to such feeding. T1, T2 and T3 birds were feed restricted (128 g of daily feed bird−1) from 40 to 44, 40 to 45 and 40 to 46 wk of age, respectively. T4 and T5 birds were also feed restricted at the same level as the other groups to 44 wk of age and then were full fed from 44 to 45 and 44 to 46 wk of age, respectively. To facilitate study of follicular recruitment and yolk deposition, hens were fed 10 g of oil-soluble red and black dyes, daily, on alternate days, beginning at 42 wk of age. Birds were killed on day 0 (44 wk; T1), day 7 (45 wk; T2, T4), or day 14 (46 wk; T3, T5). Full-fed hens consumed approximately 100 g more feed per day than did feed-restricted hens, with marked increases in feed intake on the first day of full feeding. After 7 d of ad libitum feeding, significant increases were seen in body weight, liver weight, percent liver fat, plasma lipid concentration, ovary weight, and the incidence of a double hierarchy (simultaneous development) of large follicles. After 14 d of ad libitum feeding, significant increases were also observed in absolute fat-pad weight, individual weights of the four largest preovulatory follicles and number of large preovulatory follicles. The increased number of large follicles in the ovary was not associated with any change in egg production. It is apparent that the morphological disruptions associated with overfeeding broiler breeder hens can be identified within 7 d of full feeding, while any effects on egg production are not seen within the first 14 d of ad libitum feeding. Key words: Broiler breeder, feed intake, yolk deposition, ovarian morphology, egg production

An experiment was carried out with the objective of evaluating the addition of 25-hydroxycholecalciferol (25(OH) D3) in diets of broiler breeder hens. The experiment used Cobb 500 broiler breeder hens and was allotted to a complete randomized design with four treatments and eight replications of twenty females and two males each. The treatments consisted of vitamin premixes with 2,000 and 3,400 IU/kg diet vitamin D3 as the only source of vitamin or 2,000 IU D3 plus 35 or 69 mg/t of 25(OH) D3. Results of this experiment indicated that 25(OH) D3 had no significant effect on egg production parameters from 32 to 67 weeks. The supplementation of 25(OH) D3 resulted in better quality egg shells evaluated by the specific gravity at 60 weeks of age, regardless of the dosage. No significant differences were observed for hatchability of broiler breeder fertile eggs at 54 and 64 weeks. At 64 weeks, the hatch residue breakout showed less embryo mortality at the third week for treatments receiving 2,000 UI D3 in the diet and less embryo mortality at the second week of development from hens aged 67 weeks and supplemented with 2,000IU D3 and 2,000IU D3+ 69 mg 25(OH)D3. It was concluded that the supplementation with 25-hydroxycholecalciferol with cholecalciferol had similar effects as the diets with vitamin D3 as the only source on the productive performance of broiler breeder hens.
